In most states and in all Canadianprovinces, the law requireswearing safety belts. Here is why:

You never know if you will bein a crash. If you do have a crash,you do not know if it will be aserious one.

A few crashes are mild, and somecrashes can be so serious that evenbuckled up, a person would notsurvive. But most crashes arein between. In many of them, peoplewho buckle up can survive andsometimes walk away. Withoutsafety belts they could have beenbadly hurt or killed.

After more than 40 years of safetybelts in vehicles, the facts are clear.In most crashes buckling up doesmatter... a lot!

Why Safety Belts WorkWhen you ride in or on anything,you go as fast as it goes.

Take the simplest vehicle. Supposeit is just a seat on wheels.

Put someone on it. Get it up to speed. Then stop thevehicle. The rider does not stop.

The person keeps going untilstopped by something. In a realvehicle, it could be the windshield...

or the instrument panel... or the safety belts!

With safety belts, you slow down asthe vehicle does. You get more timeto stop. You stop over more distance,and your strongest bones take theforces. That is why safety belts makesuch good sense.

Questions and Answers AboutSafety Belts

Q: Will I be trapped in the vehicleafter a crash if I am wearing asafety belt?

A: You could be — whether you arewearing a safety belt or not. Butyour chance of being consciousduring and after an accident, soyou can unbuckle and get out, ismuch greater if you are belted.And you can unbuckle a safetybelt, even if you are upside down.

Q: If my vehicle has airbags,why should I have to wearsafety belts?

A: Airbags are supplementalsystems only; so they work withsafety belts — not instead ofthem. Whether or not an airbagis provided, all occupantsstill have to buckle up to get themost protection. That is truenot only in frontal collisions, butespecially in side and othercollisions.

Q: If I am a good driver, and Inever drive far from home,why should I wear safetybelts?

A: You may be an excellent driver,but if you are in a crash — evenone that is not your fault — youand your passenger(s) can behurt. Being a good driver does notprotect you from things beyondyour control, such as bad drivers.

Most accidents occur within25 miles (40 km) of home. Andthe greatest number of seriousinjuries and deaths occur atspeeds of less than 40 mph(65 km/h).

Safety belts are for everyone.

How to Wear Safety BeltsProperlyThis section is only for people ofadult size.

Be aware that there are specialthings to know about safety belts andchildren. And there are different rulesfor smaller children and infants. If achild will be riding in the vehicle, seeOlder Children on page 1-30 orInfants and Young Children onpage 1-32. Follow those rules foreveryone’s protection.

It is very important for all occupantsto buckle up. Statistics show thatunbelted people are hurt more oftenin crashes than those who arewearing safety belts.Occupants who are not buckled upcan be thrown out of the vehiclein a crash. And they can strikeothers in the vehicle who arewearing safety belts.

First, before you or yourpassenger(s) wear a safety belt,there is important information youshould know.

Sit up straight and always keep yourfeet on the floor in front of you.The lap part of the belt should beworn low and snug on the hips, justtouching the thighs. In a crash,this applies force to the strong pelvicbones and you would be lesslikely to slide under the lap belt.

If you slid under it, the belt wouldapply force on your abdomen.This could cause serious or evenfatal injuries. The shoulder beltshould go over the shoulderand across the chest. These partsof the body are best able to take beltrestraining forces.

The shoulder belt locks if there is asudden stop or crash.

Q: What is wrong with this?

A: The belt is twisted acrossthe body.

{ CAUTION

You can be seriously injured by atwisted belt. In a crash, you wouldnot have the full width of the beltto spread impact forces. If a beltis twisted, make it straight so itcan work properly, or ask yourdealer/retailer to fix it.

Lap-Shoulder BeltAll seating positions in the vehiclehave a lap-shoulder belt.

If you are using a rear seatingposition with a detachable safetybelt and the safety belt is notattached, see Third Row Seats onpage 1-12 for instruction onreconnecting the safety belt to themini-buckle.

The following instructions explainhow to wear a lap-shoulder beltproperly.

1. Adjust the seat, if the seat isadjustable, so you can sit upstraight. To see how, see “Seats”in the Index.

2. Pick up the latch plate and pullthe belt across you. Do not letit get twisted.The lap-shoulder belt may lock ifyou pull the belt across youvery quickly. If this happens, letthe belt go back slightly tounlock it. Then pull the beltacross you more slowly.If the shoulder portion of apassenger belt is pulled out allthe way, the child restraintlocking feature may be engaged.If this happens, let the belt goback all the way and start again.

Shoulder Belt Height AdjusterThe vehicle has a shoulder beltheight adjuster for the driverand right front passenger seatingpositions.

Adjust the height so that theshoulder portion of the belt iscentered on the shoulder. The beltshould be away from the faceand neck, but not falling off of theshoulder. Improper shoulderbelt height adjustment could reducethe effectiveness of the safetybelt in a crash.

To move it down, push down onthe button (A) and move the heightadjuster to the desired position. Youcan move the height adjuster up bypushing up on the shoulder beltguide.

After the adjuster is set to the desiredposition, try to move it down withoutpushing the button to make sure ithas locked into position.

Safety Belt PretensionersThis vehicle has safety beltpretensioners for the front outboardoccupants. Although the safetybelt pretensioners cannot be seen,they are part of the safety beltassembly. They can help tightenthe safety belts during the earlystages of a moderate to severefrontal, near frontal, or rear crash ifthe threshold conditions forpretensioner activation are met.And, for vehicles with side impactairbags, safety belt pretensionerscan help tighten the safety belts in aside crash or a rollover event.

Pretensioners work only once. If thepretensioners activate in a crash,they will need to be replaced,and probably other new parts for thevehicle’s safety belt system. SeeReplacing Restraint SystemParts After a Crash on page 1-64.

Rear Safety Belt ComfortGuidesRear shoulder belt comfort guidesmay provide added safety beltcomfort for older children who haveoutgrown booster seats and forsome adults. When installed on ashoulder belt, the comfort guidepositions the shoulder belt awayfrom the neck and head.

There is a guide for each outboardpassenger position in the second rowseat and all passenger positions inthe third row. Here is how to install acomfort guide to the safety belt:

1. For the outboard positions,remove the guide from its storageclip on the interior body.For the third row center position,locate the comfort guide which islocated in a storage pocket, atthe top of the seat, under theheadrest on the driver’s side ofthe vehicle. To access the

comfort guide, you will first needto move the headrest forward bypulling on the handle behind theseatback. The comfort guide willnow be accessible.

Pull the comfort guide out of itsstorage location and thenreturn the headrest to its uprightposition.The elastic cord on the comfortguide is adjustable. You canmake it longer or shorterby squeezing both ends of theplastic adjuster.

To remove and store the comfortguide, squeeze the belt edgestogether so that the safety belt canbe removed from the guide.Slide the guide into its storagelocation or on its storage clip.

Safety Belt Use DuringPregnancySafety belts work for everyone,including pregnant women. Like alloccupants, they are more likelyto be seriously injured if they do notwear safety belts.

A pregnant woman should wear alap-shoulder belt, and the lap portionshould be worn as low as possible,below the rounding, throughoutthe pregnancy.

The best way to protect the fetus isto protect the mother. When asafety belt is worn properly,it is more likely that the fetus will notbe hurt in a crash. For pregnantwomen, as for anyone, the key tomaking safety belts effective iswearing them properly.

Safety Belt ExtenderIf the vehicle’s safety belt will fastenaround you, you should use it.

But if a safety belt is not longenough, your dealer/retailer willorder you an extender. When yougo in to order it, take the heaviestcoat you will wear, so the extenderwill be long enough for you.To help avoid personal injury, donot let someone else use it, and useit only for the seat it is made to fit.The extender has been designed foradults. Never use it for securingchild seats. To wear it, attach it tothe regular safety belt. For moreinformation, see the instructionsheet that comes with the extender.

Child Restraints

Older Children

Older children who have outgrownbooster seats should wear thevehicle’s safety belts.

The manufacturer’s instructions thatcome with the booster seat, statethe weight and height limitations for

that booster. Use a booster seatwith a lap-shoulder belt untilthe child passes the below fit test:

• Sit all the way back on theseat. Do the knees bend at theseat edge? If yes, continue.If no, return to the booster seat.

• Buckle the lap-shoulderbelt. Does the shoulder belt reston the shoulder? If yes,continue. If no, try using the rearsafety belt comfort guide. See“Rear Safety Belt ComfortGuides” under Lap-Shoulder Belton page 1-24 for moreinformation. If the shoulder beltstill does not rest on the shoulder,then return to the booster seat.

• Does the lap belt fit low and snugon the hips, touching the thighs?If yes, continue. If no, returnto the booster seat.

• Can proper safety belt fit bemaintained for the length ofthe trip? If yes, continue. If no,return to the booster seat.

Q: What is the proper way towear safety belts?

A: An older child should wear alap-shoulder belt and get theadditional restraint a shoulderbelt can provide. The shoulderbelt should not cross the face orneck. The lap belt should fitsnugly below the hips, justtouching the top of the thighs.This applies belt force tothe child’s pelvic bones in acrash. It should never be wornover the abdomen, whichcould cause severe or even fatalinternal injuries in a crash.

Also see “Rear Safety Belt ComfortGuides” under Lap-Shoulder Belton page 1-24.

According to accident statistics,children and infants are safer whenproperly restrained in a childrestraint system or infant restraintsystem secured in a rear seatingposition.

Infants and YoungChildrenEveryone in a vehicle needsprotection! This includes infants andall other children. Neither thedistance traveled nor the age andsize of the traveler changes theneed, for everyone, to use safetyrestraints. In fact, the law in everystate in the United States and inevery Canadian province sayschildren up to some age must berestrained while in a vehicle.

{ CAUTION

Children can be seriously injuredor strangled if a shoulder belt iswrapped around their neck and thesafety belt continues to tighten.Never leave children unattended ina vehicle and never allow childrento play with the safety belts.

Airbags plus lap-shoulder belts offerprotection for adults and olderchildren, but not for young childrenand infants. Neither the vehicle’ssafety belt system nor its airbagsystem is designed for them. Everytime infants and young childrenride in vehicles, they should havethe protection provided byappropriate child restraints.

Children who are not restrainedproperly can strike other people, orcan be thrown out of the vehicle.

{ CAUTION

Never do this.

Never hold an infant or a childwhile riding in a vehicle. Due tocrash forces, an infant or a childwill become so heavy it is notpossible to hold it during a crash.For example, in a crash at only25 mph (40 km/h), a 12 lb (5.5 kg)infant will suddenly become a240 lb (110 kg) force on aperson’s arms. An infant shouldbe secured in an appropriaterestraint.

Q: What are the different types ofadd-on child restraints?

A: Add-on child restraints, which arepurchased by the vehicle’sowner, are available in four basictypes. Selection of a particularrestraint should take intoconsideration not only the child’sweight, height, and age but alsowhether or not the restraint will becompatible with the motor vehiclein which it will be used.

For most basic types of childrestraints, there are manydifferent models available. Whenpurchasing a child restraint, besure it is designed to be used in amotor vehicle. If it is, the restraintwill have a label saying that itmeets federal motor vehiclesafety standards.

The restraint manufacturer’sinstructions that come with therestraint state the weightand height limitations for aparticular child restraint. Inaddition, there are many kinds ofrestraints available for childrenwith special needs.

{ CAUTION

To reduce the risk of neck andhead injury during a crash, infantsneed complete support. This isbecause an infant’s neck is notfully developed and its headweighs so much compared withthe rest of its body. In a crash, aninfant in a rear-facing childrestraint settles into the restraint,so the crash forces can bedistributed across the strongestpart of an infant’s body, the backand shoulders. Infants shouldalways be secured in rear-facingchild restraints.

{ CAUTION

A young child’s hip bones are stillso small that the vehicle’s regularsafety belt may not remain low onthe hip bones, as it should.Instead, it may settle up aroundthe child’s abdomen. In a crash,the belt would apply force on abody area that is unprotected byany bony structure. This alonecould cause serious or fatalinjuries. To reduce the risk ofserious or fatal injuries during acrash, young children shouldalways be secured in appropriatechild restraints.

{ CAUTION

A child can be seriously injured orkilled in a crash if the child restraintis not properly secured in thevehicle. Secure the child restraintproperly in the vehicle using thevehicle’s safety belt or LATCHsystem, following the instructionsthat came with that child restraintand the instructions in this manual.

To help reduce the chance of injury,the child restraint must be secured inthe vehicle. Child restraint systemsmust be secured in vehicle seats bylap belts or the lap belt portion of alap-shoulder belt, or by the LATCHsystem. See Lower Anchors andTethers for Children (LATCH) onpage 1-38 for more information.

A child can be endangered in a crashif the child restraint is not properlysecured in the vehicle.

When securing an add-on childrestraint, refer to the instructions thatcome with the restraint which maybe on the restraint itself or in abooklet, or both, and to this manual.The child restraint instructions areimportant, so if they are notavailable, obtain a replacementcopy from the manufacturer.

Keep in mind that an unsecuredchild restraint can move around in acollision or sudden stop and injurepeople in the vehicle. Be sure toproperly secure any child restraint inthe vehicle — even when no child isin it.

A label on the sun visor says, “Neverput a rear-facing child restraint in thefront.” This is because the risk to therear-facing child is so great, if theairbag deploys.

{ CAUTION

A child in a rear-facing childrestraint can be seriously injured orkilled if the right front passengerairbag inflates. This is because theback of the rear-facing childrestraint would be very close to theinflating airbag. A child in aforward-facing child restraint can

Lower Anchors andTethers for Children(LATCH)The LATCH system holds a childrestraint during driving or in a crash.This system is designed to makeinstallation of a child restraint easier.The LATCH system uses anchorsin the vehicle and attachmentson the child restraint that are madefor use with the LATCH system.

Make sure that a LATCH-compatiblechild restraint is properly installedusing the anchors, or use thevehicle’s safety belts to secure therestraint, following the instructionsthat came with that restraint, andalso the instructions in this manual.

When installing a child restraint witha top tether, you must also use eitherthe lower anchors or the safety beltsto properly secure the child restraint.A child restraint must never beattached using only the top tetherand anchor.

In order to use the LATCH system inyour vehicle, you need a childrestraint that has LATCHattachments. The child restraintmanufacturer will provide you withinstructions on how to use the childrestraint and its attachments. Thefollowing explains how to attach achild restraint with these attachmentsin your vehicle.

Not all vehicle seating positions orchild restraints have lower anchorsand attachments or top tetheranchors and attachments.

Top Tether Anchor

A top tether (A, C) anchors thetop of the child restraint to thevehicle. A top tether anchor is builtinto the vehicle. The top tetherattachment (B) on the child restraintconnects to the top tether anchorin the vehicle in order to reduce theforward movement and rotationof the child restraint during drivingor in a crash.

Your child restraint may havea single tether (A) or a dualtether (C). Either will have a singleattachment (B) to secure the toptether to the anchor.

Some child restraints with toptethers are designed for use with orwithout the top tether beingattached. Others require the toptether always to be attached.In Canada, the law requires thatforward-facing child restraints havea top tether, and that the tetherbe attached. Be sure to read andfollow the instructions for yourchild restraint.

If the child restraint does not have atop tether, one can be obtained,in kit form, for many child restraints.Ask the child restraint manufacturerwhether or not a kit is available.

CAUTION (Continued)

cause the anchor or attachment tocome loose or even break duringa crash. A child or others couldbe injured. To reduce the risk ofserious or fatal injuries during acrash, attach only one childrestraint per anchor.

{ CAUTION

Children can be seriously injuredor strangled if a shoulder belt iswrapped around their neck andthe safety belt continues totighten. Buckle any unused safetybelts behind the child restraint sochildren cannot reach them. Pullthe shoulder belt all the way outof the retractor to set the lock, ifyour vehicle has one, after thechild restraint has been installed.

Notice: Do not let the LATCHattachments rub against thevehicle’s safety belts. This maydamage these parts. If necessary,move buckled safety belts toavoid rubbing the LATCHattachments.

Do not fold the empty rear seatwith a safety belt buckled. Thiscould damage the safety belt orthe seat. Unbuckle and return thesafety belt to its stowed position,before folding the seat.

Securing a ChildRestraint in the RightFront Seat PositionThe vehicle has airbags. A rearseat is a safer place to secure aforward-facing child restraint. SeeWhere to Put the Restraint onpage 1-36.

In addition, the vehicle has apassenger sensing system which isdesigned to turn off the rightfront passenger frontal airbag andseat-mounted side impact airbagunder certain conditions. SeePassenger Sensing System onpage 1-57 and Passenger AirbagStatus Indicator on page 3-36for more information, includingimportant safety information.

A label on the sun visor says,“Never put a rear-facing child seatin the front.” This is because the riskto the rear-facing child is so great,if the airbag deploys.

{ CAUTION

A child in a rear-facing childrestraint can be seriously injured orkilled if the right front passengerairbag inflates. This is because theback of the rear-facing childrestraint would be very close to theinflating airbag. A child in aforward-facing child restraint canbe seriously injured or killed if theright front passenger airbaginflates and the passenger seat isin a forward position.

Airbag SystemThe vehicle has the followingairbags:

• A frontal airbag for the driver.

• A frontal airbag for the right frontpassenger.

• A seat-mounted side impactairbag for the driver.

• A seat-mounted side impactairbag for the right frontpassenger.

• A roof-rail airbag for the driver,passenger seated directlybehind the driver, and the thirdrow outboard passenger position.

• A roof-rail airbag for the rightfront passenger, passengerseated directly behind the rightfront passenger, and the third rowoutboard passenger position.

All of the airbags in the vehicle willhave the word AIRBAG embossedin the trim or on an attachedlabel near the deployment opening.

For frontal airbags, the wordAIRBAG will appear on the middlepart of the steering wheel forthe driver and on the instrumentpanel for the right front passenger.

With seat-mounted side impactairbags, the word AIRBAGwill appear on the side of theseatback closest to the door.

With roof-rail airbags, the wordAIRBAG will appear along theheadliner or trim.

Airbags are designed to supplementthe protection provided by safetybelts. Even though today’s airbagsare also designed to help reducethe risk of injury from the force of aninflating bag, all airbags mustinflate very quickly to do their job.

Here are the most important thingsto know about the airbag system:

{ CAUTION

You can be severely injured orkilled in a crash if you are notwearing your safety belt — even ifyou have airbags. Airbags aredesigned to work with safetybelts, but do not replace them.Also, airbags are not designed todeploy in every crash. In somecrashes safety belts are your onlyrestraint. See When Should anAirbag Inflate? on page 1-53.

Wearing your safety belt during acrash helps reduce your chanceof hitting things inside the vehicleor being ejected from it. Airbagsare “supplemental restraints” tothe safety belts. Everyone in yourvehicle should wear a safety beltproperly — whether or not there isan airbag for that person.

{ CAUTION

Airbags inflate with great force,faster than the blink of an eye.Anyone who is up against, or veryclose to, any airbag when itinflates can be seriously injured orkilled. Do not sit unnecessarilyclose to the airbag, as you wouldbe if you were sitting on the edgeof your seat or leaning forward.Safety belts help keep you inposition before and during acrash. Always wear your safetybelt, even with airbags. The drivershould sit as far back as possiblewhile still maintaining control ofthe vehicle.

Occupants should not lean on orsleep against the door or sidewindows in seating positions withseat-mounted side impact airbagsand/or roof-rail airbags.

{ CAUTION

Children who are up against, orvery close to, any airbag when itinflates can be seriously injured orkilled. Airbags plus lap-shoulderbelts offer protection for adults andolder children, but not for youngchildren and infants. Neitherthe vehicle’s safety belt systemnor its airbag system is designedfor them. Young children andinfants need the protection that achild restraint system can provide.Always secure children properly inyour vehicle. To read how, seeOlder Children on page 1-30 orInfants and Young Children onpage 1-32.

There is an airbag readiness lighton the instrument panel cluster,which shows the airbag symbol.

The system checks the airbagelectrical system for malfunctions.The light tells you if there is anelectrical problem. See AirbagReadiness Light on page 3-36 formore information.

{ CAUTION

If something is between anoccupant and an airbag, theairbag might not inflate properly orit might force the object into thatperson causing severe injury oreven death. The path of aninflating airbag must be keptclear. Do not put anythingbetween an occupant and anairbag, and do not attach or putanything on the steering wheelhub or on or near any otherairbag covering.

Do not use seat accessories thatblock the inflation path of aseat-mounted side impact airbag.

Never secure anything to the roofof a vehicle with roof-rail airbagsby routing a rope or tie downthrough any door or windowopening. If you do, the path of aninflating roof-rail airbag will beblocked.

When Should an AirbagInflate?Frontal airbags are designed toinflate in moderate to severe frontalor near-frontal crashes to helpreduce the potential for severeinjuries mainly to the driver’s or rightfront passenger’s head and chest.However, they are only designed toinflate if the impact exceeds apredetermined deploymentthreshold. Deployment thresholdsare used to predict how severea crash is likely to be in time for theairbags to inflate and help restrainthe occupants.

Whether the frontal airbags will orshould deploy is not based onhow fast your vehicle is traveling. Itdepends largely on what you hit,the direction of the impact, and howquickly your vehicle slows down.

Frontal airbags may inflate atdifferent crash speeds. For example:

• If the vehicle hits a stationaryobject, the airbags couldinflate at a different crash speedthan if the vehicle hits amoving object.

• If the vehicle hits an object thatdeforms, the airbags couldinflate at a different crash speedthan if the vehicle hits anobject that does not deform.

• If the vehicle hits a narrow object(like a pole), the airbags couldinflate at a different crash speedthan if the vehicle hits a wideobject (like a wall).

• If the vehicle goes into an objectat an angle, the airbags couldinflate at a different crash speedthan if the vehicle goes straightinto the object.

Thresholds can also vary withspecific vehicle design.

Frontal airbags are not intended toinflate during vehicle rollovers,rear impacts, or in many sideimpacts.

In addition, the vehicle hasdual-stage frontal airbags.Dual-stage airbags adjust therestraint according to crash severity.The vehicle has electronic frontalsensors, which help the sensingsystem distinguish between amoderate frontal impact and a moresevere frontal impact. For moderatefrontal impacts, dual-stage airbagsinflate at a level less than fulldeployment. For more severe frontalimpacts, full deployment occurs.

The vehicle has seat-mounted sideimpact and roof-rail airbags. SeeAirbag System on page 1-50.Seat-mounted side impact androof-rail airbags are intendedto inflate in moderate to severe sidecrashes. In addition, these roof-railairbags are intended to inflate duringa rollover or in a severe frontal

impact. Seat-mounted side impactand roof-rail airbags will inflate if thecrash severity is above thesystem’s designed threshold level.The threshold level can varywith specific vehicle design.

Seat-mounted side impact airbagsare not intended to inflate infrontal impacts, near-frontal impacts,rollovers, or rear impacts. Roof-railairbags are not intended to inflate inrear impacts. A seat-mountedside impact airbag is intended todeploy on the side of the vehicle thatis struck. Both roof-rail airbagswill deploy when either side of thevehicle is struck, or if the sensingsystem predicts that the vehicleis about to roll over, or in a severefrontal impact.

In any particular crash, no one cansay whether an airbag shouldhave inflated simply because of thedamage to a vehicle or becauseof what the repair costs were.For frontal airbags, inflation isdetermined by what the vehicle hits,the angle of the impact, and howquickly the vehicle slows down. Forseat-mounted side impact androof-rail airbags, deploymentis determined by the location andseverity of the side impact. Ina rollover event, roof-rail airbagdeployment is determined bythe direction of the roll.

What Makes an AirbagInflate?In a deployment event, the sensingsystem sends an electrical signaltriggering a release of gas from theinflator. Gas from the inflator fillsthe airbag causing the bag to breakout of the cover and deploy. Theinflator, the airbag, and relatedhardware are all part of the airbagmodule.

Frontal airbag modules are locatedinside the steering wheel andinstrument panel. For vehicles withseat-mounted side impact airbags,there are airbag modules in the sideof the front seatbacks closest tothe door. For vehicles with roof-railairbags, there are airbag modulesin the ceiling of the vehicle, near theside windows that have occupantseating positions.

How Does an AirbagRestrain?In moderate to severe frontal ornear frontal collisions, even beltedoccupants can contact the steeringwheel or the instrument panel.In moderate to severe sidecollisions, even belted occupantscan contact the inside of the vehicle.

Airbags supplement the protectionprovided by safety belts.

Frontal airbags distribute the forceof the impact more evenly overthe occupant’s upper body, stoppingthe occupant more gradually.Seat-mounted side impact androof-rail airbags distribute the forceof the impact more evenly overthe occupant’s upper body.

Rollover capable roof-rail airbagsare designed to help containthe head and chest of occupants inthe outboard seating positions inthe first, second, and third rows. Therollover capable roof-rail airbagsare designed to help reduce the riskof full or partial ejection in rolloverevents, although no system canprevent all such ejections.

But airbags would not help in manytypes of collisions, primarilybecause the occupant’s motion isnot toward those airbags. See WhenShould an Airbag Inflate? onpage 1-53 for more information.

Airbags should never be regardedas anything more than a supplementto safety belts.

What Will You See Afteran Airbag Inflates?After the frontal airbags andseat-mounted side impact airbagsinflate, they quickly deflate, soquickly that some people may noteven realize an airbag inflated.Roof-rail airbags may still be at leastpartially inflated for some timeafter they deploy. Some componentsof the airbag module may be hotfor several minutes. For location ofthe airbag modules, see WhatMakes an Airbag Inflate? onpage 1-55.

The parts of the airbag that comeinto contact with you may be warm,but not too hot to touch. There maybe some smoke and dust comingfrom the vents in the deflatedairbags. Airbag inflation does notprevent the driver from seeing out ofthe windshield or being able to steerthe vehicle, nor does it preventpeople from leaving the vehicle.

{ CAUTION

When an airbag inflates, there maybe dust in the air. This dust couldcause breathing problems forpeople with a history of asthma orother breathing trouble. To avoidthis, everyone in the vehicle shouldget out as soon as it is safe to doso. If you have breathing problemsbut cannot get out of the vehicleafter an airbag inflates, then getfresh air by opening a window or adoor. If you experience breathingproblems following an airbagdeployment, you should seekmedical attention.

The vehicle has a feature that mayautomatically unlock the doors,turn the interior lamps on, and turnthe hazard warning flashers onwhen the airbags inflate. You canlock the doors, turn the interiorlamps off, and turn the hazardwarning flashers off by using thecontrols for those features.

If a person of adult-size is sitting inthe right front passenger seat,but the off indicator is lit, it could bebecause that person is not sittingproperly in the seat.

If this happens, use the followingsteps to allow the system to detectthat person and enable the rightfront passenger frontal airbag:

1. Turn the vehicle off.

2. Remove any additional materialfrom the seat, such as blankets,cushions, seat covers, seatheaters, or seat massagers.

3. Place the seatback in the fullyupright position.

4. Have the person sit upright in theseat, centered on the seatcushion, with legs comfortablyextended.

5. Restart the vehicle and have theperson remain in this position fortwo to three minutes after theon indicator is lit.

Additional Factors AffectingSystem OperationSafety belts help keep the passengerin position on the seat during vehiclemaneuvers and braking, which helpsthe passenger sensing systemmaintain the passenger airbagstatus. See “Safety Belts” and “ChildRestraints” in the Index for additionalinformation about the importance ofproper restraint use.

A thick layer of additional material,such as a blanket or cushion, oraftermarket equipment such as seatcovers, seat heaters, and seatmassagers can affect how well thepassenger sensing systemoperates. We recommend that younot use seat covers or otheraftermarket equipment except whenapproved by GM for your specificvehicle. See Adding Equipmentto Your Airbag-Equipped Vehicle onpage 1-62 for more informationabout modifications that can affecthow the system operates.

A wet seat can affect theperformance of the passengersensing system. Here is how:

• The passenger sensing systemmay turn off the passenger airbagwhen liquid is soaked into theseat. If this happens, the offindicator will be lit, and the airbagreadiness light on the instrumentpanel will also be lit.

• Liquid pooled on the seat that hasnot soaked in may make it morelikely that the passenger sensingsystem will enable (turn on) thepassenger airbag while a childrestraint or child occupant is onthe seat. If the passenger airbagis turned on, the on indicator willbe lit.

If the passenger seat gets wet, drythe seat immediately. If theairbag readiness light is lit, do notinstall a child restraint or allowanyone to occupy the seat. SeeAirbag Readiness Light onpage 3-36 for important safetyinformation.

The on indicator may be lit if anobject, such as a briefcase,handbag, grocery bag, laptop orother electronic device, is put on anunoccupied seat. If this is not desiredremove the object from the seat.

{ CAUTION

Stowing of articles under thepassenger seat or between thepassenger seat cushion andseatback may interfere with theproper operation of the passengersensing system.

Servicing YourAirbag-Equipped VehicleAirbags affect how the vehicleshould be serviced. There are partsof the airbag system in severalplaces around the vehicle. Yourdealer/retailer and the servicemanual have information aboutservicing the vehicle and the airbagsystem.

To purchase a service manual, seeService Publications OrderingInformation on page 7-15.

{ CAUTION

For up to 10 seconds after theignition is turned off and thebattery is disconnected, an airbagcan still inflate during improperservice. You can be injured if youare close to an airbag when itinflates. Avoid yellow connectors.They are probably part of theairbag system. Be sure to followproper service procedures, andmake sure the person performingwork for you is qualified to do so.

Adding Equipment toYour Airbag-EquippedVehicleQ: Is there anything I might add to

or change about the vehiclethat could keep the airbagsfrom working properly?

A: Yes. If you add things thatchange the vehicle’s frame,bumper system, height, front endor side sheet metal, they maykeep the airbag system fromworking properly. Changing ormoving any parts of the frontseats, safety belts, the airbagsensing and diagnostic module,steering wheel, instrumentpanel, roof-rail airbag modules,ceiling headliner or pillargarnish trim, front sensors, sideimpact sensors, rolloversensor module, or airbag wiringcan affect the operation ofthe airbag system.

In addition, the vehicle has apassenger sensing system for theright front passenger position,which includes sensors that arepart of the passenger seat. Thepassenger sensing system maynot operate properly if the originalseat trim is replaced with non-GMcovers, upholstery or trim, or withGM covers, upholstery or trimdesigned for a different vehicle.Any object, such as anaftermarket seat heater or acomfort enhancing pad or device,installed under or on top of theseat fabric, could also interferewith the operation of thepassenger sensing system.This could either prevent properdeployment of the passengerairbag(s) or prevent thepassenger sensing system fromproperly turning off the passengerairbag(s). See PassengerSensing System on page 1-57.

Reading LampsThe vehicle has reading lamps thatalso act as the dome lamp. Pressthe button to turn them on and off.

Electric PowerManagementThe vehicle has Electric PowerManagement (EPM) that estimatesthe battery’s temperature and stateof charge. It then adjusts the voltagefor best performance and extendedlife of the battery.

When the battery’s state of chargeis low, the voltage is raised slightlyto quickly bring the charge back up.

When the state of charge is high, thevoltage is lowered slightly to preventovercharging. If the vehicle has avoltmeter gage or a voltage displayon the Driver Information Center(DIC), you may see the voltage moveup or down. This is normal. If there isa problem, an alert will be displayed.

The battery can be discharged atidle if the electrical loads are veryhigh. This is true for all vehicles. Thisis because the generator (alternator)may not be spinning fast enough atidle to produce all the power that isneeded for very high electrical loads.

A high electrical load occurs whenseveral of the following are on,such as: headlamps, high beams,fog lamps, rear window defogger,climate control fan at high speed,heated seats, engine cooling fans,trailer loads, and loads plugged intoaccessory power outlets.

EPM works to prevent excessivedischarge of the battery. It doesthis by balancing the generator’soutput and the vehicle’s electricalneeds. It can increase engineidle speed to generate more power,whenever needed. It can temporarilyreduce the power demands ofsome accessories.

Normally, these actions occurin steps or levels, without beingnoticeable. In rare cases at thehighest levels of corrective action,this action may be noticeable tothe driver. If so, a Driver InformationCenter (DIC) message might bedisplayed, such as BATTERYSAVER ACTIVE, BATTERYVOLTAGE LOW, or LOW BATTERY.If this message is displayed, it isrecommended that the driver reducethe electrical loads as much aspossible. See DIC Warnings andMessages on page 3-58.

Battery Run-DownProtectionThis feature helps preventthe battery from being drained,if the interior courtesy lamps,reading/map lamps, visor vanitylamps or trunk lamp are accidentallyleft on. If any of these lamps are lefton, they automatically turn off after10 minutes, if the ignition is off. Thelamps will not come back on againuntil one of the following occurs:

• The ignition is turned on.

• The exterior lamps control isturned off, then on again.

The headlamps will timeout after10 minutes, if they are manuallyturned on with the ignition on or off.

MalfunctionIndicator LampCheck Engine LightA computer system called OBD II(On-Board Diagnostics-SecondGeneration) monitors operationof the fuel, ignition, and emissioncontrol systems. It ensures thatemissions are at acceptable levelsfor the life of the vehicle, helping toproduce a cleaner environment.

This light comes on when theignition is on, but the engine is notrunning, as a check to show it isworking. If it does not, have thevehicle serviced by your dealer/retailer.

If the check engine light comeson and stays on, while the engineis running, this indicates that thereis an OBD II problem and serviceis required.

Malfunctions often are indicated bythe system before any problem isapparent. Being aware of the lightcan prevent more serious damageto the vehicle. This system assiststhe service technician in correctlydiagnosing any malfunction.

Notice: If the vehicle iscontinually driven with thislight on, after a while, theemission controls might notwork as well, the vehicle’s fueleconomy might not be as good,and the engine might not runas smoothly. This could lead tocostly repairs that might not becovered by the vehicle warranty.

This light comes on during amalfunction in one of two ways:

Light Flashing: A misfire conditionhas been detected. A misfireincreases vehicle emissions andcould damage the emission controlsystem on the vehicle. Diagnosisand service might be required.

The following can prevent moreserious damage to the vehicle:

• Reduce vehicle speed.

• Avoid hard accelerations.

• Avoid steep uphill grades.

• If towing a trailer, reduce theamount of cargo being hauledas soon as it is possible.

If the light continues to flash,when it is safe to do so, stop thevehicle. Find a safe place to park thevehicle. Turn the key off, wait at least10 seconds, and restart the engine.If the light is still flashing, follow theprevious steps and see your dealer/retailer for service as soon aspossible.

Light On Steady: An emissioncontrol system malfunction has beendetected on the vehicle. Diagnosisand service might be required.

An emission system malfunctionmight be corrected by checking thefollowing items:

• Make sure the fuel cap is fullyinstalled. See Filling the Tank onpage 5-8. The diagnostic systemcan determine if the fuel caphas been left off or improperlyinstalled. A loose or missingfuel cap allows fuel to evaporateinto the atmosphere. A fewdriving trips with the cap properlyinstalled should turn the light off.

• If the vehicle has been driventhrough a deep puddle of water,the vehicle’s electrical systemmight be wet. The condition isusually corrected when theelectrical system dries out.A few driving trips shouldturn the light off.

• Make sure to fuel the vehiclewith quality fuel. Poor fuel qualitycauses the engine not to run asefficiently as designed and maycause: stalling after start-up,stalling when the vehicle ischanged into gear, misfiring,hesitation on acceleration,or stumbling on acceleration.These conditions might go awayonce the engine is warmed up.If one or more of these conditionsoccurs, change the fuel brandused. It will require at least onefull tank of the proper fuel to turnthe light off.See Gasoline Octane onpage 5-5.

If none of the above have made thelight turn off, your dealer/retailer cancheck the vehicle. The dealer/retailerhas the proper test equipment anddiagnostic tools to fix any mechanicalor electrical problems that mighthave developed.

Emissions Inspection andMaintenance ProgramsSome state/provincial and localgovernments have or might beginprograms to inspect the emissioncontrol equipment on the vehicle.Failure to pass this inspectioncould prevent getting a vehicleregistration.

Here are some things to know tohelp the vehicle pass an inspection:

• The vehicle will not pass thisinspection if the check enginelight is on with the engine running,or if the key is in ON/RUN and thelight is not on.

• The vehicle will not pass thisinspection if the OBD II (on-boarddiagnostic) system determinesthat critical emission controlsystems have not beencompletely diagnosed by thesystem. The vehicle wouldbe considered not ready forinspection. This can happenif the battery has recently beenreplaced or if the battery has rundown. The diagnostic systemis designed to evaluate criticalemission control systems duringnormal driving. This can takeseveral days of routine driving.If this has been done and thevehicle still does not pass theinspection for lack of OBD IIsystem readiness, your dealer/retailer can prepare the vehiclefor inspection.

TRIP A and TRIP B

Press the trip/fuel button untilTRIP A or TRIP B displays.This display shows the currentdistance traveled in either miles (mi)or kilometers (km) since the lastreset for each trip odometer. Bothtrip odometers can be used atthe same time. Pressing the tripodometer reset stem will alsodisplay the trip odometers.

Each trip odometer can be resetto zero separately by pressing theset/reset button or the trip odometerreset stem while the desired tripodometer is displayed.

The trip odometer has a featurecalled the retro-active reset. This canbe used to set the trip odometer tothe number of miles (kilometers)driven since the ignition was lastturned on. This can be used ifthe trip odometer is not resetat the beginning of the trip.

To use the retro-active reset feature,press and hold the set/reset buttonfor at least four seconds. The tripodometer will display the numberof miles (mi) or kilometers (km)driven since the ignition was lastturned on and the vehicle wasmoving. Once the vehicle beginsmoving, the trip odometer willaccumulate mileage. For example, ifthe vehicle was driven 5 miles (8 km)before it is started again, and thenthe retro-active reset feature isactivated, the display will show5 miles (8 km). As the vehiclebegins moving, the display willthen increase to 5.1 miles (8.2 km),5.2 miles (8.4 km), etc.

If the retro-active reset feature isactivated after the vehicle is started,but before it begins moving, thedisplay will show the number ofmiles (mi) or kilometers (km) thatwere driven during the last ignitioncycle.

RANGE

Press the trip/fuel button untilRANGE displays. This displayshows the approximate numberof remaining miles (mi) orkilometers (km) the vehiclecan be driven without refueling.The display will show LOW if thefuel level is low.

The fuel range estimate is basedon an average of the vehicle’s fueleconomy over recent driving historyand the amount of fuel remaining inthe fuel tank. This estimate willchange if driving conditions change.For example, if driving in traffic andmaking frequent stops, this displaymay read one number, but if thevehicle is driven on a freeway, thenumber may change even thoughthe same amount of fuel is in thefuel tank. This is because differentdriving conditions produce differentfuel economies. Generally, freewaydriving produces better fuel economythan city driving. Fuel range cannotbe reset.

Compass Calibration

The compass can be manuallycalibrated. Only calibrate thecompass in a magnetically cleanand safe location, such as an openparking lot, where driving the vehiclein circles is not a danger. It issuggested to calibrate away fromtall buildings, utility wires, manholecovers, or other industrial structures,if possible.

If CAL should ever appear in theDIC display, the compass shouldbe calibrated.

If the DIC display does not show aheading, for example, N for North,or the heading does not change aftermaking turns, there may be a strongmagnetic field interfering with thecompass. Such interference maybe caused by a magnetic CB or cellphone antenna mount, a magneticemergency light, magnetic note padholder, or any other magnetic item.Turn off the vehicle, move themagnetic item, then turn on thevehicle and calibrate the compass.

To calibrate the compass, use thefollowing procedure:

Compass Calibration Procedure

1. Before calibrating the compass,make sure the compass zoneis set to the variance zone inwhich the vehicle is located.See “Compass Variance (Zone)Procedure” earlier in this section.

Do not operate any switchessuch as window, sunroof, climatecontrols, seats, etc. during thecalibration procedure.

Compressed Audio

The radio also plays discs thatcontain both uncompressed CDaudio (.CDA files) and MP3/WMAfiles. The radio plays both file formatsin the order in which they wererecorded to the disc.

MP3/WMA Format

Creating an MP3/WMA disc on apersonal computer:

• Make sure the MP3/WMA filesare recorded on a CD-R orCD-RW disc.

• Do not mix standard audio andMP3/WMA files on one disc.

• The CD player is able toread and play a maximum of50 folders, 15 playlists, and acombined total of 512 foldersand files.

• Create a folder structure thatmakes it easy to find songswhile driving. Organize songsby albums using one folder foreach album. Each folder or albumshould contain 18 songs or less.

• Avoid subfolders. The system cansupport up to eight subfoldersdeep, however, keep the totalnumber of folders to a minimumin order to reduce the complexityand confusion in trying to locate aparticular folder during playback.

• Make sure playlists have a .mp3or .wpl extension (other fileextensions might not work).

• Minimize the length of the file,folder, or playlist names. Long file,folder, or playlist names, or acombination of a large number offiles and folders, or playlists couldcause the player to be unable toplay up to the maximum numberof files, folders, playlists, or

sessions. To play a large numberof files, folders, playlists orsessions, minimize the length ofthe file, folder, or playlist name.Long names also take up morespace on the display, potentiallygetting cut off.

• Finalize the audio disc beforeburning it. Trying to add music toan existing disc could cause thedisc not to function in the player.

Change playlists by using Sc andcT folder buttons, the f knob, orthe SEEK arrows. An MP3/WMACD-R or CD-RW that was recordedusing no file folders can be played.If a CD-R or CD-RW contains morethan the maximum of 50 folders,15 playlists, and a combined totalof 512 folders and files, the playeraccesses and navigates up to themaximum, but all items over themaximum are not accessible.

• The CD player (lower slot) isable to read and play a maximumcombination of 512 files andfolders. The DVD player (upperslot) is able to read 255 folders,15 playlists and 40 sessions.

• Create a folder structure thatmakes it easy to find songswhile driving. Organize songsby albums using one folder foreach album. Each folder or albumshould contain 18 songs or less.

• Avoid subfolders. The system cansupport up to eight subfoldersdeep, however, keep the totalnumber of folders to a minimumin order to reduce the complexityand confusion in trying to locate aparticular folder during playback.

• Make sure playlists havea .m3u, .wpl or .pls extensionas other file extensions mightnot work.

• Minimize the length of the file,folder or playlist names. Long file,folder, or playlist names, or acombination of a large number offiles and folders, or playlists couldcause the player to be unable toplay up to the maximum numberof files, folders, playlists, orsessions. To play a large numberof files, folders, playlists, orsessions, minimize the length ofthe file, folder, or playlist name.Long names also take up morespace on the display, potentiallygetting cut off.

• Finalize the audio disc beforeburning it. Trying to add music toan existing disc could cause thedisc not to function in the player.

AMThe range for most AM stations isgreater than for FM, especially atnight. The longer range can causestation frequencies to interferewith each other. For better radioreception, most AM radio stationsboost the power levels during theday, and then reduce these levelsduring the night. Static can alsooccur when things like storms andpower lines interfere with radioreception. When this happens, tryreducing the treble on the radio.

FM StereoFM signals only reach about10 to 40 miles (16 to 65 km).Although the radio has a built-inelectronic circuit that automaticallyworks to reduce interference,some static can occur, especiallyaround tall buildings or hills, causingthe sound to fade in and out.

XM™ Satellite Radio ServiceXM Satellite Radio Servicegives digital radio reception fromcoast-to-coast in the 48 contiguousUnited States, and in Canada. Justas with FM, tall buildings or hills caninterfere with satellite radio signals,causing the sound to fade in and out.In addition, traveling or standingunder heavy foliage, bridges,garages, or tunnels may cause lossof the XM signal for a period of time.

Cellular Phone UsageCellular phone usage may causeinterference with the vehicle’s radio.This interference may occur whenmaking or receiving phone calls,charging the phone’s battery,or simply having the phone on.This interference causes anincreased level of static whilelistening to the radio. If static isreceived while listening to theradio, unplug the cellular phoneand turn it off.

Multi-Band AntennaThe multi-band antenna is locatedon the roof of the vehicle. This typeof antenna is used with the AM/FMradio, as well as OnStar® and theXM™ Satellite Radio ServiceSystem, if the vehicle has thesefeatures. Keep this antenna clearof snow and ice build up for clearradio reception. If the vehicle hasa sunroof, the performance of theradio system may be affected if thesunroof is open. Loading items ontothe roof of the vehicle can interferewith the performance of the radiosystem and, if the vehicle has thisfeature, OnStar®. Make sure themulti-band antenna is not obstructed.

Defensive DrivingDefensive driving means “alwaysexpect the unexpected.” The firststep in driving defensively is towear your safety belt — See SafetyBelts: They Are for Everyone onpage 1-15.

{ CAUTION

Assume that other road users(pedestrians, bicyclists, and otherdrivers) are going to be carelessand make mistakes. Anticipatewhat they might do and be ready.In addition:

• Allow enough followingdistance between you andthe driver in front of you.

• Focus on the task of driving.

Driver distraction can causecollisions resulting in injury orpossible death. These simpledefensive driving techniques couldsave your life.

Drunk Driving

{ CAUTION

Drinking and then driving isvery dangerous. Your reflexes,perceptions, attentiveness, andjudgment can be affected by evena small amount of alcohol. Youcan have a serious — or evenfatal — collision if you drive afterdrinking. Do not drink and drive orride with a driver who has beendrinking. Ride home in a cab; or ifyou are with a group, designate adriver who will not drink.

Death and injury associated withdrinking and driving is a globaltragedy.

Alcohol affects four things thatanyone needs to drive a vehicle:judgment, muscular coordination,vision, and attentiveness.

In recent years,more than 17,000 annual motorvehicle-related deaths have beenassociated with the use of alcohol,with about 250,000 people injured.

For persons under 21, it is againstthe law in every U.S. state to drinkalcohol. There are good medical,psychological, and developmentalreasons for these laws.

The obvious way to eliminate theleading highway safety problemis for people never to drink alcoholand then drive.

Medical research shows that alcoholin a person’s system can make crashinjuries worse, especially injuries tothe brain, spinal cord, or heart.

This means that when anyone whohas been drinking — driver orpassenger — is in a crash, thatperson’s chance of being killed orpermanently disabled is higher thanif the person had not been drinking.

Control of a VehicleThe following three systemshelp to control the vehicle whiledriving — brakes, steering,and accelerator. At times, as whendriving on snow or ice, it is easyto ask more of those controlsystems than the tires and roadcan provide. Meaning, you canlose control of the vehicle.See StabiliTrak® System onpage 4-5.

Adding non-dealer/non-retaileraccessories can affect vehicleperformance. See Accessoriesand Modifications on page 5-3.

BrakingSee Brake System Warning Light onpage 3-38.

Braking action involves perceptiontime and reaction time. Decidingto push the brake pedal isperception time. Actually doing it isreaction time.

Average reaction time is aboutthree-fourths of a second. But thatis only an average. It might beless with one driver and as long astwo or three seconds or morewith another. Age, physicalcondition, alertness, coordination,and eyesight all play a part. Sodo alcohol, drugs, and frustration.But even in three-fourths of asecond, a vehicle moving at 60 mph(100 km/h) travels 66 feet (20 m).That could be a lot of distance in anemergency, so keeping enoughspace between the vehicleand others is important.

And, of course, actual stoppingdistances vary greatly with thesurface of the road, whether it ispavement or gravel; the condition ofthe road, whether it is wet, dry, or icy;tire tread; the condition of the brakes;the weight of the vehicle; and theamount of brake force applied.

Avoid needless heavy braking. Somepeople drive in spurts — heavyacceleration followed by heavybraking — rather than keeping pacewith traffic. This is a mistake.The brakes might not have time tocool between hard stops. The brakeswill wear out much faster with a lot ofheavy braking. Keeping pace withthe traffic and allowing realisticfollowing distances eliminates a lot ofunnecessary braking. That meansbetter braking and longer brake life.

If the engine ever stops while thevehicle is being driven, brakenormally but do not pump the brakes.If the brakes are pumped, the pedalcould get harder to push down.

If the engine stops, there will still besome power brake assist but it will beused when the brake is applied.Once the power assist is used up, itcan take longer to stop and the brakepedal will be harder to push.

Adding non-dealer/non-retaileraccessories can affect vehicleperformance. See Accessoriesand Modifications on page 5-3.

Antilock BrakeSystem (ABS)This vehicle has the Antilock BrakeSystem (ABS), an advancedelectronic braking system that helpsprevent a braking skid.

When the engine is started and thevehicle begins to drive away,ABS checks itself. A momentarymotor or clicking noise might beheard while this test is going on,and it might even be noticed thatthe brake pedal moves a little.This is normal.

If there is a problem with ABS,this warning light stays on.See Antilock Brake System (ABS)Warning Light on page 3-39.

Let us say the road is wet and youare driving safely. Suddenly, ananimal jumps out in front of you.You slam on the brakes andcontinue braking. Here is whathappens with ABS:

A computer senses that the wheelsare slowing down. If one of thewheels is about to stop rolling,the computer will separately workthe brakes at each wheel.

ABS can change the brake pressureto each wheel, as required, fasterthan any driver could. This canhelp the driver steer aroundthe obstacle while braking hard.

As the brakes are applied, thecomputer keeps receiving updateson wheel speed and controls brakingpressure accordingly.

Remember: ABS does not changethe time needed to get a footup to the brake pedal or alwaysdecrease stopping distance.If you get too close to the vehiclein front of you, there will not beenough time to apply the brakes ifthat vehicle suddenly slows or stops.Always leave enough room upahead to stop, even with ABS.

Using ABSDo not pump the brakes. Just holdthe brake pedal down firmly andlet antilock work. The antilock pumpor motor operating might be heardand the brake pedal might be felt topulsate, but this is normal.

Braking in EmergenciesABS allows the driver to steer andbrake at the same time. In manyemergencies, steering can help morethan even the very best braking.

Brake Assist

This vehicle has a Brake Assistfeature designed to assist the driverin stopping or decreasing vehiclespeed in emergency drivingconditions. This feature uses thestability system hydraulic brakecontrol module to supplement thepower brake system underconditions where the driver hasquickly and forcefully appliedthe brake pedal in an attempt toquickly stop or slow down thevehicle. The stability systemhydraulic brake control moduleincreases brake pressure at eachcorner of the vehicle until theABS activates. Minor brake pedalpulsations or pedal movementduring this time is normal and thedriver should continue to applythe brake pedal as the driving

situation dictates The Brake Assistfeature will automatically disengagewhen the brake pedal is releasedor brake pedal pressure is quicklydecreased.

StabiliTrak® SystemThe vehicle has the StabiliTraksystem which combines antilockbrake, traction and stability controlsystems and helps the drivermaintain directional control of thevehicle in most driving conditions.

When you first start the vehicle andbegin to drive away, the systemperforms several diagnostic checksto ensure there are no problems.The system may be heard orfelt while it is working. This isnormal and does not mean thereis a problem with the vehicle.The system should initializebefore the vehicle reaches 20 mph(32 km/h). In some cases, it maytake approximately two miles(3.2 km) of driving before the systeminitializes.

If theseconditions are observed, turn thevehicle off, wait 15 seconds, andthen turn it back on again to resetthe system. If any of these messagesstill appear on the Driver InformationCenter (DIC), the vehicle should betaken in for service. For moreinformation on the DIC messages,see Driver Information Center (DIC)on page 3-47.

The StabiliTrak light will flash on theinstrument panel cluster when thesystem is both on and activated.

The system may be heard or feltwhile it is working; this is normal.

The traction control disable button islocated on the instrument panelbelow the climate controls.

The traction control part ofStabiliTrak can be turned off bypressing and releasing the tractioncontrol disable button.

Traction control can be turned onby pressing and releasing thetraction control disable buttonif not automatically shut off for anyother reason.

When the traction control systemis turned off, the StabiliTrak lightand the appropriate traction controloff message will be displayedon the DIC to warn the driver.

The vehicle will still havebrake-traction control whentraction control is off, but will notbe able to use the engine speedmanagement system. See “TractionControl Operation” next for moreinformation.

When the traction control systemhas been turned off, system noisesmay be heard and felt as a resultof the brake-traction control working.

It is recommended to leave thesystem on for normal drivingconditions, but it may be necessaryto turn the system off if the vehicleis stuck in sand, mud, ice orsnow, and you want to “rock”the vehicle to attempt to free it.It may also be necessary to turnoff the system when driving inextreme off-road conditions wherehigh wheel spin is required. SeeIf Your Vehicle is Stuck in Sand,Mud, Ice, or Snow on page 4-15.

Traction Control OperationThe traction control system ispart of the StabiliTrak system.Traction control limits wheel spinby reducing engine power to thewheels (engine speed management)and by applying brakes to eachindividual wheel (brake-tractioncontrol) as necessary.

The traction control system isenabled automatically when thevehicle is started. It will activate andthe StabiliTrak light will flash if itsenses that any of the wheels arespinning or beginning to lose tractionwhile driving. If traction control isturned off, only the brake-tractioncontrol portion of traction controlwill work. The engine speedmanagement will be disabled. In thismode, engine power is not reducedautomatically and the driven wheelscan spin more freely. This cancause the brake-traction control toactivate constantly.

Notice: If the wheel(s) ofone axle is allowed to spinexcessively while the StabiliTrak,ABS and brake warning lights andany relevant DIC messages aredisplayed, the transfer case couldbe damaged. The repairs wouldnot be covered by the vehiclewarranty. Reduce engine powerand do not spin the wheel(s)excessively while these lightsand messages are displayed.

The traction control system mayactivate on dry or rough roadsor under conditions such as heavyacceleration while turning orabrupt upshifts/downshifts of thetransmission. When this happens, areduction in acceleration may benoticed, or a noise or vibration maybe heard. This is normal.

If cruise control is being used whenthe system activates, the StabiliTraklight will flash and cruise controlwill automatically disengage.

Cruise control may be reengagedwhen road conditions allow.See Cruise Control on page 3-9.

StabiliTrak may also turn offautomatically if it determines that aproblem exists with the system.If the problem does not clear itselfafter restarting the vehicle, see yourdealer/retailer for service.

All-Wheel Drive (AWD)SystemIf the vehicle has this feature,engine power is sent to all fourwheels when extra traction isneeded. This is like four-wheel drive,but there is no separate lever orswitch to engage or disengage theaxle. It is fully automatic, andadjusts itself as needed for roadconditions.

When using a compact spare tire onthe AWD equipped vehicle, theAWD system automatically detectsthe presence of the compactspare and the AWD is disabled.

To restore the AWD operation andprevent excessive wear on theAWD system, replace the compactspare with a full-size tire assoon as possible. See CompactSpare Tire on page 5-79 for moreinformation.

SteeringPower SteeringIf power steering assist is lostbecause the engine stops or thesystem is not functioning, the vehiclecan be steered but it will takemore effort.

Variable Effort SteeringIf the vehicle has this steeringsystem, the system continuouslyadjusts the effort felt whensteering at all vehicle speeds.It provides ease when parking,yet a firm, solid feel at highwayspeeds.

Steering TipsIt is important to take curves at areasonable speed.

Traction in a curve depends on thecondition of the tires and theroad surface, the angle at whichthe curve is banked, and vehiclespeed. While in a curve, speedis the one factor that can becontrolled.

If there is a need to reduce speed,do it before entering the curve,while the front wheels are straight.

Try to adjust the speed so youcan drive through the curve.Maintain a reasonable, steadyspeed. Wait to accelerate until outof the curve, and then accelerategently into the straightaway.

Steering in EmergenciesThere are times when steering canbe more effective than braking.For example, you come over a hilland find a truck stopped in yourlane, or a car suddenly pullsout from nowhere, or a child dartsout from between parked carsand stops right in front of you.These problems can be avoidedby braking — if you can stop in time.But sometimes you cannot stop intime because there is no room.That is the time for evasiveaction — steering around theproblem.

The vehicle can perform very wellin emergencies like these.First, apply the brakes. See Brakingon page 4-3. It is better to removeas much speed as possible froma collision. Then steer aroundthe problem, to the left or rightdepending on the space available.

An emergency like this requiresclose attention and a quick decision.If holding the steering wheel at therecommended 9 and 3 o’clockpositions, it can be turned a full180 degrees very quickly withoutremoving either hand. But you haveto act fast, steer quickly, and just asquickly straighten the wheel onceyou have avoided the object.

The fact that such emergencysituations are always possible is agood reason to practice defensivedriving at all times and wearsafety belts properly.

Off-Road RecoveryThe vehicle’s right wheels can dropoff the edge of a road onto theshoulder while driving.

If the level of the shoulder is onlyslightly below the pavement,recovery should be fairly easy.Ease off the accelerator and then, ifthere is nothing in the way, steer sothat the vehicle straddles the edge ofthe pavement. Turn the steeringwheel 3 to 5 inches, 8 to 13 cm,(about one-eighth turn) until the rightfront tire contacts the pavementedge. Then turn the steering wheel togo straight down the roadway.

PassingPassing another vehicle on atwo-lane road can be dangerous.To reduce the risk of dangerwhile passing:

• Look down the road, to the sides,and to crossroads for situationsthat might affect a successfulpass. If in doubt, wait.

• Watch for traffic signs,pavement markings, and linesthat could indicate a turn oran intersection. Never cross asolid or double-solid line on yourside of the lane.

• Do not get too close to thevehicle you want to pass. Doingso can reduce your visibility.

• Wait your turn to pass a slowvehicle.

• When you are being passed,ease to the right.

Loss of ControlLet us review what driving expertssay about what happens whenthe three control systems — brakes,steering, and acceleration — donot have enough friction where thetires meet the road to do whatthe driver has asked.

In any emergency, do not give up.Keep trying to steer and constantlyseek an escape route or area ofless danger.

SkiddingIn a skid, a driver can lose controlof the vehicle. Defensive driversavoid most skids by takingreasonable care suited to existingconditions, and by not overdrivingthose conditions. But skids arealways possible.

The three types of skids correspondto the vehicle’s three controlsystems. In the braking skid,the wheels are not rolling.

In the steering or cornering skid,too much speed or steering in acurve causes tires to slip and losecornering force. And in theacceleration skid, too much throttlecauses the driving wheels to spin.

If the vehicle starts to slide, easeyour foot off the accelerator pedaland quickly steer the way youwant the vehicle to go. If you startsteering quickly enough, thevehicle may straighten out. Alwaysbe ready for a second skid if itoccurs.

Of course, traction is reduced whenwater, snow, ice, gravel, or othermaterial is on the road. For safety,slow down and adjust your drivingto these conditions. It is important toslow down on slippery surfacesbecause stopping distance is longerand vehicle control more limited.

While driving on a surface withreduced traction, try your best toavoid sudden steering, acceleration,or braking, including reducingvehicle speed by shifting to a lowergear. Any sudden changes couldcause the tires to slide. You mightnot realize the surface is slipperyuntil the vehicle is skidding. Learn torecognize warning clues — suchas enough water, ice, or packedsnow on the road to make amirrored surface — and slow downwhen you have any doubt.

Remember: Any Antilock BrakeSystem (ABS) helps avoid only thebraking skid.

Driving at NightNight driving is more dangerous thanday driving because some driversare likely to be impaired — by alcoholor drugs, with night vision problems,or by fatigue.

Night driving tips include:

• Drive defensively.

• Do not drink and drive.

• Reduce headlamp glare byadjusting the inside rearviewmirror.

• Slow down and keep more spacebetween you and other vehiclesbecause headlamps can onlylight up so much road ahead.

• Watch for animals.

• When tired, pull off the road.

• Do not wear sunglasses.

• Avoid staring directly intoapproaching headlamps.

• Keep the windshield and all glasson your vehicle clean — insideand out.

• Keep your eyes moving,especially during turns or curves.

No one can see as well at night asin the daytime. But, as we getolder, these differences increase.A 50-year-old driver might needat least twice as much light to seethe same thing at night as a20-year-old.

Driving in Rain and onWet RoadsRain and wet roads can reducevehicle traction and affect yourability to stop and accelerate.Always drive slower in these typesof driving conditions and avoiddriving through large puddles anddeep-standing or flowing water.

{ CAUTION

Wet brakes can cause crashes.They might not work as well in aquick stop and could causepulling to one side. You couldlose control of the vehicle.

After driving through a largepuddle of water or a car/vehiclewash, lightly apply the brakepedal until the brakes worknormally.

Flowing or rushing water createsstrong forces. Driving throughflowing water could cause yourvehicle to be carried away. If thishappens, you and other vehicleoccupants could drown. Do notignore police warnings and bevery cautious about trying to drivethrough flowing water.

HydroplaningHydroplaning is dangerous.Water can build up under yourvehicle’s tires so they actually rideon the water. This can happen if theroad is wet enough and you aregoing fast enough. When yourvehicle is hydroplaning, it has littleor no contact with the road.

There is no hard and fast rule abouthydroplaning. The best advice isto slow down when the road is wet.

Other Rainy Weather TipsBesides slowing down, other wetweather driving tips include:

• Allow extra following distance.

• Pass with caution.

• Keep windshield wipingequipment in good shape.

• Keep the windshield washer fluidreservoir filled.

• Have good tires with proper treaddepth. See Tires on page 5-37.

• Turn off cruise control.

Before Leaving on aLong TripTo prepare your vehicle for a longtrip, consider having it servicedby your dealer/retailer beforedeparting.

Things to check on your owninclude:

• Windshield Washer Fluid:Reservoir full? Windowsclean — inside and outside?

• Wiper Blades: In good shape?

• Fuel, Engine Oil, Other Fluids:All levels checked?

• Lamps: Do they all work andare lenses clean?

• Tires: Are treads good?Are tires inflated torecommended pressure?

• Weather and Maps: Safe totravel? Have up-to-date maps?

Highway HypnosisAlways be alert and pay attention toyour surroundings while driving.If you become tired or sleepy, find asafe place to park your vehicleand rest.

Other driving tips include:

• Keep the vehicle well ventilated.

• Keep interior temperature cool.

• Keep your eyes moving — scanthe road ahead and to the sides.

• Check the rearview mirror andvehicle instruments often.

Hill and Mountain RoadsDriving on steep hills or throughmountains is different than drivingon flat or rolling terrain. Tips fordriving in these conditions include:

• Keep the vehicle servicedand in good shape.

• Check all fluid levels and brakes,tires, cooling system, andtransmission.

• Going down steep or long hills,shift to a lower gear.

{ CAUTION

If you do not shift down, the brakescould get so hot that they wouldnot work well. You would thenhave poor braking or even nonegoing down a hill. You could crash.Shift down to let the engine assistthe brakes on a steep downhillslope.

{ CAUTION

Coasting downhill in N (Neutral) orwith the ignition off is dangerous.The brakes will have to do all thework of slowing down and theycould get so hot that they wouldnot work well. You would thenhave poor braking or even nonegoing down a hill. You could crash.Always have the engine runningand the vehicle in gear when goingdownhill.

• Stay in your own lane. Do notswing wide or cut across thecenter of the road. Drive atspeeds that let you stay in yourown lane.

• Top of hills: Be alert — somethingcould be in your lane (stalled car,accident).

• Pay attention to special roadsigns (falling rocks area, windingroads, long grades, passing orno-passing zones) and takeappropriate action.

Winter DrivingDriving on Snow or IceDrive carefully when there is snowor ice between the tires and theroad, creating less traction or grip.Wet ice can occur at about 32°F(0°C) when freezing rain begins tofall, resulting in even less traction.Avoid driving on wet ice or infreezing rain until roads can betreated with salt or sand.

Drive with caution, whatever thecondition. Accelerate gentlyso traction is not lost. Acceleratingtoo quickly causes the wheelsto spin and makes the surface underthe tires slick, so there is evenless traction.

Try not to break the fragile traction.If you accelerate too fast, thedrive wheels will spin and polish thesurface under the tires even more.

For more information aboutcarbon monoxide, see EngineExhaust on page 2-30.

Snow can trap exhaust gasesunder your vehicle. This cancause deadly CO (carbonmonoxide) gas to get inside.CO could overcome you and killyou. You cannot see it or smell it,so you might not know it is in yourvehicle. Clear away snow fromaround the base of your vehicle,especially any that is blocking theexhaust.

Run the engine for short periodsonly as needed to keep warm,but be careful.

To save fuel, run the engine for onlyshort periods as needed to warmthe vehicle and then shut the engineoff and close the window most ofthe way to save heat. Repeat this

until help arrives but only when youfeel really uncomfortable fromthe cold. Moving about to keepwarm also helps.

If it takes some time for help toarrive, now and then when you runthe engine, push the acceleratorpedal slightly so the engineruns faster than the idle speed.This keeps the battery charged torestart the vehicle and to signalfor help with the headlamps. Do thisas little as possible to save fuel.

If Your Vehicle is Stuck inSand, Mud, Ice, or SnowSlowly and cautiously spin thewheels to free the vehicle whenstuck in sand, mud, ice, or snow.See Rocking Your Vehicle to Get ItOut on page 4-16.

If the vehicle has a traction system,it can often help to free a stuckvehicle. Refer to the vehicle’straction system in the Index.

If stuck too severely for the tractionsystem to free the vehicle, turnthe traction system off and use therocking method.

{ CAUTION

If you let your vehicle’s tires spinat high speed, they can explode,and you or others could beinjured. The vehicle can overheat,causing an engine compartmentfire or other damage. Spin thewheels as little as possible andavoid going above 35 mph(55 km/h) as shown on thespeedometer.

Steps for Determining CorrectLoad Limit

1. Locate the statement“The combined weightof occupants and cargoshould never exceed XXX kgor XXX lbs” on your vehicle’splacard.

2. Determine the combinedweight of the driver andpassengers that will be ridingin your vehicle.

3. Subtract the combined weightof the driver and passengersfrom XXX kg or XXX lbs.

4. The resulting figure equalsthe available amount ofcargo and luggage loadcapacity. For example,if the “XXX” amount equals1400 lbs and there will befive 150 lb passengers inyour vehicle, the amount ofavailable cargo and luggageload capacity is 650 lbs(1400 − 750 (5 x 150) =650 lbs).

5. Determine the combinedweight of luggage andcargo being loaded on thevehicle. That weight may notsafely exceed the availablecargo and luggage loadcapacity calculated in Step 4.

6. If your vehicle will be towing atrailer, the load from yourtrailer will be transferred toyour vehicle. Consult thismanual to determine howthis reduces the availablecargo and luggage loadcapacity for your vehicle.

The Certification/Tire labelalso tells you the maximumweights for the front andrear axles, called the GrossAxle Weight Rating (GAWR).To find out the actual loads onyour front and rear axles,you need to go to a weighstation and weigh your vehicle.Your dealer/retailer can helpyou with this. Be sure to spreadout your load equally on bothsides of the centerline.

Never exceed the GVWR foryour vehicle or the GAWRfor either the front or rear axle.

{ CAUTION

Do not load the vehicle anyheavier than the Gross VehicleWeight Rating (GVWR), oreither the maximum front orrear Gross Axle Weight Rating(GAWR). If you do, parts onthe vehicle can break, and itcan change the way yourvehicle handles. These couldcause you to lose control andcrash. Also, overloading canshorten the life of the vehicle.

Notice: Overloading yourvehicle may cause damage.Repairs would not be coveredby your warranty. Do notoverload your vehicle.

Recreational VehicleTowingRecreational vehicle towingmeans towing the vehicle behindanother vehicle – such as behinda motorhome. The two mostcommon types of recreationalvehicle towing are known asdinghy towing and dolly towing.Dinghy towing is towing the vehiclewith all four wheels on the ground.Dolly towing is towing the vehiclewith two wheels on the ground andtwo wheels up on a device knownas a dolly.

Here are some important things toconsider before recreationalvehicle towing:

• What is the towing capacity of thetowing vehicle? Be sure to readthe tow vehicle manufacturer’srecommendations.

• What is the distance that will betravelled? Some vehicles haverestrictions on how far and howlong they can tow.

• Is the proper towing equipmentgoing to be used? See yourdealer/retailer or traileringprofessional for additional adviceand equipment recommendations.

• Is the vehicle ready to be towed?Just as preparing the vehiclefor a long trip, make sure thevehicle is prepared to be towed.See Before Leaving on a LongTrip on page 4-12.

Dinghy Towing

If the vehicle is front-wheel-drive,it can be dinghy towed from thefront. These vehicles may also betowed by putting the front wheels ona dolly. See “Dolly Towing” laterin this section.

If the vehicle is all-wheel-drive, itcan be dinghy towed from the front.These vehicles can also be towedby placing them on a platform trailerwith all four wheels off of theground. These vehicles cannot betowed using a dolly.

For vehicles being dinghy towed,the vehicle should be run atthe beginning of each day and ateach RV fuel stop for aboutfive minutes. This will ensureproper lubrication of transmissioncomponents. Re-install the fuseto start the vehicle.

To tow the vehicle from the frontwith all four wheels on the ground:

1. Position the vehicle to towand then secure it to thetowing vehicle.

2. Shift the transmission toP (Park) and turn the ignitionto LOCK/OFF.

3. Set the parking brake.

4. Turn the ignition toACC/ACCESSORY.

5. Shift the transmission toN (Neutral).

6. To prevent the battery fromdraining while the vehicle isbeing towed, remove the50 amp BATT1 fuse from theunderhood fuse block andstore in a safe location.See Underhood Fuse Blockon page 5-90.

7. Release the parking brake.

Notice: If the vehicle istowed without performingeach of the steps listed under“Dinghy Towing,” the automatictransmission could be damaged.Be sure to follow all steps ofthe dinghy towing procedure priorto and after towing the vehicle.

Notice: If 65 mph (105 km/h) isexceeded while towing thevehicle, it could be damaged.Never exceed 65 mph (105 km/h)while towing the vehicle.

Once the destination is reached:

1. Set the parking brake.

2. Reinstall the 50 amp BATT1 fuseto the underhood fuse block.

3. Shift the transmission to P (Park),turn the ignition to LOCK/OFFand remove the key fromthe ignition.

4. Disconnect the vehicle from thetowing vehicle.

Notice: Do not tow a vehicle withthe front drive wheels on theground if one of the front tires is acompact spare tire. Towing withtwo different tire sizes on the frontof the vehicle can cause severedamage to the transmission.

Trailering is different than just drivingthe vehicle by itself. Trailering meanschanges in handling, acceleration,braking, durability and fuel economy.Successful, safe trailering takescorrect equipment, and it has to beused properly.

The following information has manytime-tested, important trailering tipsand safety rules. Many of these areimportant for the safety of the driverand the passengers. So please readthis section carefully before pullinga trailer.

Load-pulling components such asthe engine, transmission, rear axle,wheel assemblies and tires areforced to work harder against thedrag of the added weight. The engineis required to operate at relativelyhigher speeds and under greaterloads, generating extra heat.What’s more, the trailer addsconsiderably to wind resistance,increasing the pulling requirements.

Pulling A TrailerHere are some important points:

• There are many differentlaws, including speed limitrestrictions, having to do withtrailering. Make sure the rig willbe legal, not only where youlive but also where you will bedriving. A good source for thisinformation can be state orprovincial police.

• Consider using a sway control.See “Hitches” later in thissection.

• Do not tow a trailer at all duringthe first 500 miles (800 km) thenew vehicle is driven. The engine,axle or other parts could bedamaged.

• Then, during the first 500 miles(800 km) that a trailer is towed, donot drive over 50 mph (80 km/h)and do not make starts at fullthrottle. This helps the engine andother parts of the vehicle wear inat the heavier loads.

• Obey speed limit restrictionswhen towing a trailer.

• The vehicles can tow in D (Drive).Shift the transmission to a lowergear if the transmission shifts toooften under heavy loads and/orhilly conditions. See “Tow/HaulMode” later in this section.

• The vehicle is designed primarilyas a passenger and load carryingvehicle. If a trailer is towed,the vehicle will require morefrequent maintenance due to theadditional load.

Three important considerations haveto do with weight:

• The weight of the trailer.

• The weight of the trailer tongue.

• And the weight on the vehicle’stires

Weight of the TrailerHow heavy can a trailer safely be?

It depends on how the rig isused. For example, speed, altitude,road grades, outside temperatureand how much the vehicle is usedto pull a trailer are all important.It can depend on any specialequipment on the vehicle, and the

amount of tongue weight the vehiclecan carry. See “Weight of theTrailer Tongue” later in this sectionfor more information.

Maximum trailer weight is calculatedassuming only the driver is in thetow vehicle and it has all therequired trailering equipment.

The weight of additional optionalequipment, passengers and cargo inthe tow vehicle must be subtractedfrom the maximum trailer weight.

Use the following chart to determinehow much the vehicle can weigh,based upon the vehicle modeland options.

Vehicle Maximum Trailer Weight *GCWRFront-Wheel Drive 2,000 lbs (907 kg) 7,500 lbs (3 402 kg)Front-Wheel Drive, V92 Trailer Towing Package 4,500 lbs (2 041 kg) 9,500 lbs (4 309 kg)All-Wheel Drive 2,000 lbs (907 kg) 7,700 lbs (3 493 kg)All-Wheel Drive, V92 Trailer Towing Package 4,500 lbs (2 041 kg) 9,700 lbs (4 400 kg)*The Gross Combination Weight Rating (GCWR) is the total allowable weight of the completely loaded vehicle andtrailer including any passengers, cargo, equipment and conversions. The GCWR for the vehicle should not beexceeded.

Ask your dealer/retailer for ourtrailering information or advice, orwrite us at our Customer AssistanceOffices. See Customer AssistanceOffices on page 7-5 for moreinformation.

Weight of the Trailer TongueThe tongue load (A) of any trailer isan important weight to measurebecause it affects the total grossweight of the vehicle. The GrossVehicle Weight (GVW) includes thecurb weight of the vehicle, any

cargo carried in it, and the peoplewho will be riding in the vehicle.If there are a lot of options,equipment, passengers or cargo inthe vehicle, it will reduce thetongue weight the vehicle can carry,which will also reduce the trailer

weight the vehicle can tow. If towinga trailer, the tongue load must beadded to the GVW because thevehicle will be carrying that weight,too. See Loading the Vehicle onpage 4-16 for more informationabout the vehicle’s maximum loadcapacity.

If a weight-carrying hitch or aweight-distributing hitch is beingused, the trailer tongue (A) shouldweigh 10-15 percent of the totalloaded trailer weight (B).

After loading the trailer, weigh thetrailer and then the tongue,separately, to see if the weights areproper. If they aren’t, adjustmentsmight be made by moving someitems around in the trailer.

Trailering may also be limited by thevehicle’s ability to carry tongueweight. Tongue weight cannot causethe vehicle to exceed the GVWR(Gross Vehicle Weight Rating) or theRGAWR (Rear Gross Axle WeightRating). The effect of additionalweight may reduce the traileringcapacity more than the total of theadditional weight.

Consider the following example:

A vehicle model base weightis 5,500 lbs (2 495 kg); 2,800 lbs(1 270 kg) at the front axle and2,700 lbs (1 225 kg) at the rear axle.It has a GVWR of 7,200 lbs(3 266 kg), a RGAWR of 4,000 lbs(1 814 kg) and a GCWR (GrossCombination Weight Rating)of 14,000 lbs (6 350 kg).

The trailer rating should be:

Expect tongue weight to be atleast 10 percent of trailer weight(850 lbs (386 kg)) and because theweight is applied well behind therear axle, the effect on the rear axleis greater than just the weight itself,as much as 1.5 times as much.The weight at the rear axle could be850 lbs (386 kg) X 1.5 = 1,275 lbs(578 kg). Since the rear axle alreadyweighs 2,700 lbs (1 225 kg), adding1,275 lbs (578 kg) brings the total to3,975 lbs (1 803 kg). This is veryclose to, but within the limit forRGAWR as well. The vehicle is setto trailer up to 8,500 lbs (3 856 kg).

If the vehicle has many options andthere is a front seat passenger andtwo rear seat passengers with someluggage and gear in the vehicle aswell. 300 lbs (136 kg) could beadded to the front axle weight and400 lbs (181 kg) to the rear axleweight. The vehicle now weighs:

Weight is still below 7,200 lbs(3 266 kg) and you might think700 additional pounds (318 kg)should be subtracted from thetrailering capacity to stay withinGCWR limits. The maximum trailerwould only be 7,800 lbs (3 538 kg).You may go further and think thetongue weight should be limited to

less than 1,000 lbs (454 kg) toavoid exceeding GVWR. But theeffect on the rear axle must stillbe considered. Because therear axle now weighs 3,100 lbs(1 406 kg), 900 lbs (408 kg) canbe put on the rear axle withoutexceeding RGAWR. The effect oftongue weight is about 1.5 timesthe actual weight. Dividing the900 lbs (408 kg) by 1.5 leaves only600 lbs (272 kg) of tongue weightthat can be handled. Since tongueweight is usually at least 10 percentof total loaded trailer weight, expectthat the largest trailer the vehiclecan properly handle is 6,000 lbs(2 721 kg).

It is important that the vehicledoes not exceed any of itsratings — GCWR, GVWR, RGAWR,Maximum Trailer Rating or TongueWeight. The only way to be sure it isnot exceeding any of these ratings isto weigh the vehicle and trailer.

Total Weight on theVehicle’s TiresBe sure the vehicle’s tires areinflated to the upper limit for coldtires. These numbers can be foundon the Certification/Tire label.See Loading the Vehicle onpage 4-16. Make sure not to goover the GVW limit for the vehicle,including the weight of the trailertongue.

HitchesIt is important to have the correcthitch equipment. Crosswinds,large trucks going by and roughroads are a few reasons whythe right hitch is needed. Here aresome rules to follow:

• The rear bumper on the vehicleis not intended for hitches.Do not attach rental hitches orother bumper-type hitchesto it. Use only a frame-mountedhitch that does not attach tothe bumper.

Page 281: 2009 GMC Acadia Owner Manual M · 2009 GMC Acadia Owner Manual M. GENERAL MOTORS, GM, the GM Emblem, GMC, the GMC Emblem, ... it appears in this manual. This manual describes features

• Will any holes be made in thebody of the vehicle when thetrailer hitch is installed? If thereare, then be sure to seal theholes later when the hitchis removed. If the holes are notsealed, dirt, water, and deadlycarbon monoxide (CO) fromthe exhaust can get into thevehicle. See Engine Exhauston page 2-30.

Safety ChainsAlways attach chains between thevehicle and the trailer. Cross thesafety chains under the tongue ofthe trailer to help prevent the tonguefrom contacting the road if itbecomes separated from the hitch.Instructions about safety chainsmay be provided by the hitchmanufacturer or by the trailermanufacturer. Follow themanufacturer’s recommendationfor attaching safety chains anddo not attach them to the bumper.

Always leave just enough slack sothe rig can turn. Never allow safetychains to drag on the ground.

Trailer BrakesA loaded trailer that weighs morethan 1,000 lbs (450 kg) needsto have its own brake system that isadequate for the weight of thetrailer. Be sure to read and followthe instructions for the trailer brakesso they are installed, adjustedand maintained properly.

Because the vehicle has antilockbrakes, do not try to tap into thevehicle’s hydraulic brake system.If you do, both brake systemswill not work well, or at all.

Driving with a TrailerTowing a trailer requires a certainamount of experience. Get toknow the rig before setting out forthe open road. Get acquaintedwith the feel of handling and brakingwith the added weight of the trailer.

And always keep in mind that thevehicle you are driving is now longerand not as responsive as thevehicle is by itself.

Before starting, check all trailer hitchparts and attachments, safetychains, electrical connectors, lamps,tires and mirror adjustments. If thetrailer has electric brakes, start thevehicle and trailer moving and thenapply the trailer brake controller byhand to be sure the brakes areworking. This checks the electricalconnection at the same time.

During the trip, check occasionallyto be sure that the load is secure,and that the lamps and anytrailer brakes are still working.

Following DistanceStay at least twice as far behindthe vehicle ahead as you wouldwhen driving the vehicle without atrailer. This can help to avoidsituations that require heavy brakingand sudden turns.

PassingMore passing distance is neededwhen towing a trailer. Becausethe rig is longer, it is necessary togo much farther beyond thepassed vehicle before returningto the lane.

Backing UpHold the bottom of the steeringwheel with one hand. Then, to movethe trailer to the left, move thathand to the left. To move the trailerto the right, move your hand tothe right. Always back up slowlyand, if possible, have someoneguide you.

Making TurnsNotice: Making very sharp turnswhile trailering could causethe trailer to come in contact withthe vehicle. The vehicle couldbe damaged. Avoid making verysharp turns while trailering.

When turning with a trailer, makewider turns than normal. Do thisso the trailer won’t strike softshoulders, curbs, road signs, treesor other objects. Avoid jerky orsudden maneuvers. Signal wellin advance.

Turn Signals When Towing aTrailerThe arrows on the instrument panelflash whenever signaling a turnor lane change. Properly hooked up,the trailer lamps also flash, tellingother drivers the vehicle is turning,changing lanes or stopping.

When towing a trailer, the arrowson the instrument panel flashfor turns even if the bulbs on thetrailer are burned out. For thisreason you may think other driversare seeing the signal when theyare not. It is important to checkoccasionally to be sure the trailerbulbs are still working.

Driving on GradesBecause of the added load of thetrailer, the vehicle’s engine mayoverheat on hot days, when goingup a long or steep grade with atrailer. If the engine coolanttemperature gage indicatesoverheating, turn off the airconditioning to reduce engine load,pull off the road and stop in asafe spot. Let the engine run whileparked, preferably on levelground, with the transmission inP (Park) for a few minutes beforeturning the engine off.

Reduce speed and shift to a lowergear before starting down a longor steep downgrade. If thetransmission is not shifted down, thebrakes might have to be used somuch that they would get hot and nolonger work well.

On a long uphill grade, shift downand reduce the vehicle speedto around 55 mph (88 km/h) toreduce the possibility of the engineand the transmission overheating.

Tow/Haul ModeTow/Haul is a feature that assistswhen pulling a heavy trailer ora large or heavy load. The purposeof the Tow/Haul mode is to:

• Reduce the frequency andimprove the predictability oftransmission shifts when pullinga heavy trailer or a large orheavy load.

• Provide the same solid shift feelwhen pulling a heavy trailer or alarge or heavy load as whenthe vehicle is unloaded.

• Improve control of vehicle speedwhile requiring less throttle pedalactivity when pulling a heavytrailer or a large or heavy load.

• Increase the charging systemvoltage to assist in recharginga battery installed in a trailer.

Press this button located on theconsole to turn on and turn off theTow/Haul mode.

The Tow/Haul light on theinstrument panel will come on toindicate that Tow/Haul modehas been selected.

Tow/Haul may be turned off bypressing the button again, at whichtime the indicator light on theinstrument panel will turn off.The vehicle will automatically turnoff Tow/Haul every time it is started.

Tow/Haul is designed to be mosteffective when the vehicle andtrailer combined weight is at least75 percent of the vehicle’s GrossCombined Weight Rating (GCWR).

See Weight of the Trailer earlier inthis section. Tow/Haul is mostuseful under the following drivingconditions:• When pulling a heavy trailer or a

large or heavy load throughrolling terrain.

• When pulling a heavy trailer or alarge or heavy load in stop andgo traffic.

• When pulling a heavy trailer or alarge or heavy load in busyparking lots where improved lowspeed control of the vehicle isdesired.

Operating the vehicle in Tow/Haulwhen lightly loaded or with notrailer at all will not cause damage.However, there is no benefit to theselection of Tow/Haul when thevehicle is unloaded. Such a selectionwhen unloaded may result inunpleasant engine and transmissiondriving characteristics and reducedfuel economy. Tow/Haul isrecommended only when pulling aheavy trailer or a large or heavy load.

Adding Equipment to theOutside of the VehicleThings added to the outside of thevehicle can affect the airflowaround it. This can cause windnoise and can affect fuel economyand windshield washer performance.Check with your dealer/retailerbefore adding equipment tothe outside of the vehicle.

FuelUse of the recommended fuelis an important part of the propermaintenance of this vehicle. To helpkeep the engine clean and maintainoptimum vehicle performance, werecommend the use of gasolineadvertised as TOP TIER DetergentGasoline.

Gasoline OctaneUse regular unleaded gasoline with aposted octane rating of 87 or higher.If the octane rating is less than 87,you might notice an audible knockingnoise when you drive, commonlyreferred to as spark knock. If thisoccurs, use a gasoline rated at

87 octane or higher as soon aspossible. If you are using gasolinerated at 87 octane or higher and youhear heavy knocking, the engineneeds service.

Gasoline SpecificationsAt a minimum, gasoline shouldmeet ASTM specification D 4814in the United States or CAN/CGSB-3.5 or 3.511 in Canada.Some gasolines contain anoctane-enhancing additive calledmethylcyclopentadienyl manganesetricarbonyl (MMT). We recommendagainst the use of gasolinescontaining MMT. See Additives onpage 5-6 for additional information.

California FuelIf the vehicle is certified to meetCalifornia Emissions Standards,it is designed to operate on fuelsthat meet California specifications.See the underhood emission controllabel. If this fuel is not available instates adopting California emissionsstandards, the vehicle will operatesatisfactorily on fuels meeting federalspecifications, but emission controlsystem performance might beaffected. The malfunction indicatorlamp could turn on and the vehiclemight fail a smog-check test.See Malfunction Indicator Lamp onpage 3-42. If this occurs, return toyour authorized dealer/retailer fordiagnosis. If it is determined that thecondition is caused by the type offuel used, repairs might not becovered by the vehicle warranty.

AdditivesTo provide cleaner air, all gasolinesin the United States are now requiredto contain additives that help preventengine and fuel system depositsfrom forming, allowing the emissioncontrol system to work properly.In most cases, you should not haveto add anything to the fuel. However,some gasolines contain only theminimum amount of additiverequired to meet U.S. EnvironmentalProtection Agency regulations.To help keep fuel injectors and intakevalves clean, or if the vehicleexperiences problems due to dirtyinjectors or valves, look for gasolinethat is advertised as TOP TIERDetergent Gasoline.

For customers who do not useTOP TIER Detergent Gasolineregularly, one bottle of GM FuelSystem Treatment PLUS, added tothe fuel tank at every engine oilchange, can help clean depositsfrom fuel injectors and intake valves.GM Fuel System Treatment PLUSis the only gasoline additiverecommended by General Motors.

Also, your dealer/retailer hasadditives that will help correct andprevent most deposit-relatedproblems.

Engine OverheatingThe vehicle has several indicatorsto warn of engine overheating.

There is an engine coolanttemperature gage on the instrumentpanel cluster. See Engine CoolantTemperature Gage on page 3-41.

The vehicle may also displayan ENGINE OVERHEATEDIDLE ENGINE and ENGINEOVERHEATED STOP ENGINEmessage in the Driver InformationCenter (DIC). See DIC Warningsand Messages on page 3-58.

You may decide not to lift the hoodwhen this warning appears, butinstead get service help right away.See Roadside Assistance Programon page 7-6.

If you do decide to lift the hood,make sure the vehicle is parked ona level surface.

Then check to see if the enginecooling fans are running. If theengine is overheating, both fansshould be running. If they arenot, do not continue to run theengine and have the vehicleserviced.

Notice: Engine damage fromrunning the engine withoutcoolant is not covered by thewarranty.

Notice: If the engine catches firewhile driving with no coolant, thevehicle can be badly damaged.The costly repairs would not becovered by the vehicle warranty.See Overheated Engine ProtectionOperating Mode on page 5-25 forinformation on driving to a safeplace in an emergency.

If Steam Is Coming From TheEngine Compartment

{ CAUTION

Steam from an overheated enginecan burn you badly, even if youjust open the hood. Stay awayfrom the engine if you see or hearsteam coming from it. Turn it offand get everyone away from thevehicle until it cools down. Waituntil there is no sign of steam orcoolant before you open the hood.

If you keep driving when thevehicles engine is overheated, theliquids in it can catch fire. You orothers could be badly burned.Stop the engine if it overheats,and get out of the vehicle until theengine is cool.

If No Steam Is Coming FromThe Engine CompartmentIf an engine overheat warning isdisplayed but no steam can be seenor heard, the problem may not be tooserious. Sometimes the engine canget a little too hot when the vehicle:

• Climbs a long hill on a hot day.

• Stops after high-speed driving.

• Idles for long periods in traffic.

• Tows a trailer.

If the overheat warning is displayedwith no sign of steam:

1. Turn the air conditioning off.

2. Turn the heater on to the highesttemperature and to the highestfan speed. Open the windows asnecessary.

3. If in a traffic jam, shift toN (Neutral), otherwise, shiftto the highest gear whiledriving — D (Drive) or L (Low).

If the temperature overheat gage isno longer in the overheat zone or anoverheat warning no longer displays,the vehicle can be driven. Continueto drive the vehicle slow for about10 minutes. Keep a safe vehicledistance from the car in front of you.If the warning does not come backon, continue to drive normally.

If the warning continues, pull over,stop, and park the vehicle right away.

If there is no sign of steam, idlethe engine for three minuteswhile parked. If the warning is stilldisplayed, turn off the engine until itcools down. Also, see “OverheatedEngine Protection Operating Mode”next in this section.

OverheatedEngine ProtectionOperating ModeThis emergency operating mode letsthe vehicle be driven to a safe placein an emergency situation. If anoverheated engine condition exists,an overheat protection mode whichalternates firing groups of cylindershelps prevent engine damage. In thismode, there is a significant loss inpower and engine performance.The temperature gage indicates anoverheat condition exists. Drivingextended distances and/or towing atrailer in the overheat protectionmode should be avoided.

Notice: After driving in theoverheated engine protectionoperating mode, to avoid enginedamage, allow the engine to coolbefore attempting any repair.The engine oil will be severelydegraded. Repair the cause ofcoolant loss, change the oil andreset the oil life system. SeeEngine Oil on page 5-13.

Power Steering Fluid

The power steering fluid reservoiris located toward the front of theengine compartment on thepassenger side of the vehicle. SeeEngine Compartment Overview onpage 5-12 for reservoir location.

When to Check PowerSteering FluidIt is not necessary to regularlycheck power steering fluid unlessyou suspect there is a leak in thesystem or you hear an unusualnoise. A fluid loss in this systemcould indicate a problem. Have thesystem inspected and repaired.

How to Check Power SteeringFluidTo check the power steering fluid:

1. Turn the key off and let theengine compartment cool down.

2. Remove engine oil fill cap.

3. Slide engine cover rearward andlift to remove.

4. Wipe the cap and the top of thereservoir clean.

5. Unscrew the cap and wipe thedipstick with a clean rag.

6. Replace the cap and completelytighten it.

7. Remove the cap again and lookat the fluid level on the dipstick.

The fluid level should be somewherebetween MAX and MIN line on thedipstick in room temperature. If thefluid is on or below MIN line, youshould add fluid close to MAX Line.

What to UseTo determine what kind of fluid touse, see Recommended Fluids andLubricants on page 6-12. Alwaysuse the proper fluid.

Notice: Use of the incorrect fluidmay damage the vehicle and thedamages may not be covered bythe vehicle’s warranty. Alwaysuse the correct fluid listed inRecommended Fluids andLubricants on page 6-12.

Windshield Washer FluidWhat to UseWhen adding windshieldwasher fluid, be sure to read themanufacturer’s instructions beforeuse. If the vehicle will be operating inan area where the temperature mayfall below freezing, use a fluid thathas sufficient protection againstfreezing.

Adding Washer FluidWhen the windshield washer fluidreservoir is low, a WASHER FLUIDLOW ADD FLUID message will bedisplayed on the Driver InformationCenter (DIC). See DIC Warnings andMessages on page 3-58 for moreinformation.

Open the cap with the washersymbol on it. Add washer fluiduntil the tank is full. See EngineCompartment Overview onpage 5-12 for reservoir location.

Notice:

• When using concentratedwasher fluid, follow themanufacturer’s instructionsfor adding water.

• Do not mix water withready-to-use washer fluid.Water can cause the solution tofreeze and damage your washerfluid tank and other parts of thewasher system. Also, waterdoes not clean as well aswasher fluid.

• Fill the washer fluid tank onlythree-quarters full when it isvery cold. This allows for fluidexpansion if freezing occurs,which could damage the tank ifit is completely full.

• Do not use engine coolant(antifreeze) in your windshieldwasher. It can damage thevehicle’s windshield washersystem and paint.

There are only two reasons why thebrake fluid level in the reservoirmight go down:

• The brake fluid level goes downbecause of normal brake liningwear. When new linings areinstalled, the fluid level goesback up.

• A fluid leak in the brake hydraulicsystem can also cause a low fluidlevel. Have the brake hydraulicsystem fixed, since a leak meansthat sooner or later the brakes willnot work well.

Do not top off the brake fluid. Addingfluid does not correct a leak. If fluidis added when the linings are worn,there will be too much fluid when newbrake linings are installed. Add orremove brake fluid, as necessary,only when work is done on the brakehydraulic system.

{ CAUTION

If too much brake fluid is added,it can spill on the engine and burn,if the engine is hot enough. You orothers could be burned, and thevehicle could be damaged. Addbrake fluid only when work is doneon the brake hydraulic system.

When the brake fluid falls to a lowlevel, the brake warning light comeson. See Brake System WarningLight on page 3-38.

What to Add

Use only new DOT 3 brake fluidfrom a sealed container. SeeRecommended Fluids andLubricants on page 6-12.

Always clean the brake fluidreservoir cap and the area aroundthe cap before removing it. Thishelps keep dirt from enteringthe reservoir.

{ CAUTION

With the wrong kind of fluid inthe brake hydraulic system, thebrakes might not work well. Thiscould cause a crash. Always usethe proper brake fluid.

Notice:

• Using the wrong fluid can badlydamage brake hydraulic systemparts. For example, just a fewdrops of mineral-based oil,such as engine oil, in the brakehydraulic system can damagebrake hydraulic system parts sobadly that they will have to bereplaced. Do not let someoneput in the wrong kind of fluid.

• If brake fluid is spilled on thevehicle’s painted surfaces, thepaint finish can be damaged. Becareful not to spill brake fluidon the vehicle. If you do, wash itoff immediately. See WashingYour Vehicle on page 5-83.

Brake WearThis vehicle has disc brakes.Disc brake pads have built-in wearindicators that make a high-pitchedwarning sound when the brake padsare worn and new pads are needed.The sound can come and go or beheard all the time the vehicle ismoving, except when applying thebrake pedal firmly.

{ CAUTION

The brake wear warning soundmeans that soon the brakes willnot work well. That could lead toan accident. When the brake wearwarning sound is heard, have thevehicle serviced.

Notice: Continuing to drive withworn-out brake pads couldresult in costly brake repair.

Some driving conditions or climatescan cause a brake squeal whenthe brakes are first applied or

lightly applied. This does notmean something is wrong withthe brakes.

Properly torqued wheel nuts arenecessary to help prevent brakepulsation. When tires are rotated,inspect brake pads for wear andevenly tighten wheel nuts in theproper sequence to torquespecifications in Capacities andSpecifications on page 5-94.

Brake linings should always bereplaced as complete axle sets.

Brake Pedal TravelSee your dealer/retailer if the brakepedal does not return to normalheight, or if there is a rapid increasein pedal travel. This could be a signthat brake service might be required.

Brake AdjustmentEvery time the brakes are applied,with or without the vehicle moving,the brakes adjust for wear.

Replacing Brake System PartsThe braking system on a vehicleis complex. Its many parts haveto be of top quality and work welltogether if the vehicle is to havereally good braking. The vehicle wasdesigned and tested with top-qualitybrake parts. When parts of thebraking system are replaced — forexample, when the brake liningswear down and new ones areinstalled — be sure to get newapproved replacement parts. If this isnot done, the brakes might not workproperly. For example, if someoneputs in brake linings that are wrongfor the vehicle, the balance betweenthe front and rear brakes canchange — for the worse. The brakingperformance expected can changein many other ways if the wrongreplacement brake parts areinstalled.

When to Check

Check your tires once a monthor more. Do not forget to checkthe compact spare tire, if thevehicle has one. It should be at60 psi (420 kPa). For additionalinformation regarding thecompact spare tire, see CompactSpare Tire on page 5-79.

How to Check

Use a good quality pocket-typegage to check tire pressure.You cannot tell if your tires areproperly inflated simply bylooking at them. Radial tires maylook properly inflated even whenthey are under-inflated. Checkthe tire’s inflation pressure whenthe tires are cold. Cold meansyour vehicle has been sitting forat least three hours or driven nomore than 1 mile (1.6 km).

Remove the valve cap fromthe tire valve stem. Press thetire gage firmly onto the valveto get a pressure measurement.If the cold tire inflation pressurematches the recommendedpressure on the Tire and LoadingInformation label, no furtheradjustment is necessary. If theinflation pressure is low, add airuntil you reach the recommendedamount.

If you overfill the tire, releaseair by pushing on the metal stemin the center of the tire valve.Re-check the tire pressure withthe tire gage.

Be sure to put the valve capsback on the valve stems. Theyhelp prevent leaks by keepingout dirt and moisture.

Tire Pressure MonitorSystemThe Tire Pressure Monitor System(TPMS) uses radio and sensortechnology to check tire pressurelevels. The TPMS sensors monitorthe air pressure in your vehicle’s tiresand transmit tire pressure readingsto a receiver located in the vehicle.

Each tire, including the spare(if provided), should be checkedmonthly when cold and inflated to theinflation pressure recommended bythe vehicle manufacturer on thevehicle placard or tire inflationpressure label. (If your vehicle hastires of a different size than the sizeindicated on the vehicle placard ortire inflation pressure label, youshould determine the proper tireinflation pressure for those tires.)

As an added safety feature, yourvehicle has been equipped with a tirepressure monitoring system (TPMS)that illuminates a low tire pressuretelltale when one or more of yourtires is significantly under-inflated.

Accordingly, when the low tirepressure telltale illuminates, youshould stop and check your tires assoon as possible, and inflate themto the proper pressure. Driving ona significantly under-inflated tirecauses the tire to overheat and canlead to tire failure. Under-inflationalso reduces fuel efficiency andtire tread life, and may affect thevehicle’s handling and stoppingability.

Please note that the TPMS isnot a substitute for proper tiremaintenance, and it is the driver’sresponsibility to maintain correct tirepressure, even if under-inflation hasnot reached the level to triggerillumination of the TPMS low tirepressure telltale.

Your vehicle has also been equippedwith a TPMS malfunction indicatorto indicate when the system is notoperating properly. The TPMSmalfunction indicator is combinedwith the low tire pressure telltale.When the system detects amalfunction, the telltale will flash forapproximately one minute and thenremain continuously illuminated.This sequence will continue uponsubsequent vehicle start-ups aslong as the malfunction exists.

When the malfunction indicator isilluminated, the system may not beable to detect or signal low tirepressure as intended. TPMSmalfunctions may occur for a varietyof reasons, including the installationof replacement or alternate tires orwheels on the vehicle that preventthe TPMS from functioning properly.Always check the TPMS malfunctiontelltale after replacing one or moretires or wheels on your vehicle toensure that the replacement oralternate tires and wheels allow theTPMS to continue to functionproperly.

Tire Inspection andRotationWe recommend that youregularly inspect the vehicle’stires, including the spare tire, ifthe vehicle has one, for signs ofwear or damage. See When It IsTime for New Tires on page 5-51for more information.

Tires should be rotated every5,000 to 8,000 miles (8 000 to13 000 km). See ScheduledMaintenance on page 6-3.

The purpose of a regular tirerotation is to achieve a uniformwear for all tires on the vehicle.This will ensure that the vehiclecontinues to perform most like itdid when the tires were new.

Any time you notice unusualwear, rotate the tires as soonas possible and check wheelalignment. Also check fordamaged tires or wheels.

See When It Is Time for NewTires on page 5-51 andWheel Replacement onpage 5-55.

When rotating the vehicle’s tires,always use the correct rotationpattern shown here.

Rust or dirt on a wheel, or onthe parts to which it isfastened, can make wheelnuts become loose after time.The wheel could come off andcause an accident. When youchange a wheel, remove anyrust or dirt from places wherethe wheel attaches to thevehicle. In an emergency, youcan use a cloth or a papertowel to do this; but be sure touse a scraper or wire brushlater, if needed, to get all therust or dirt off. See Changinga Flat Tire on page 5-66.

Make sure the spare tire, if thevehicle has one, is storedsecurely. Push, pull, and then tryto rotate or turn the tire. If itmoves, tighten the cable. SeeStoring a Flat or Spare Tire andTools on page 5-76.

When It Is Time forNew TiresVarious factors, such asmaintenance, temperatures,driving speeds, vehicle loading,and road conditions influence whenyou need new tires.

One way to tell when it is time fornew tires is to check the treadwearindicators, which will appearwhen the tires have only 1/16 inch(1.6 mm) or less of tread remaining.

You need new tires if any of thefollowing statements are true:

• You can see the indicators atthree or more places aroundthe tire.

• You can see cord or fabricshowing through the tire’s rubber.

• The tread or sidewall is cracked,cut, or snagged deep enough toshow cord or fabric.

• The tire has a bump, bulge,or split.

• The tire has a puncture, cut, orother damage that cannot berepaired well because of the sizeor location of the damage.

The rubber in tires degrades overtime, even if they are not beingused. This is also true for thespare tire, if the vehicle has one.Multiple conditions affect how fastthis aging takes place, includingtemperatures, loading conditions,and inflation pressure maintenance.

Buying New TiresGM has developed and matchedspecific tires for your vehicle. Theoriginal equipment tires installedon your vehicle, when it was new,were designed to meet GeneralMotors Tire Performance CriteriaSpecification (TPC Spec) systemrating. If you need replacementtires, GM strongly recommendsthat you get tires with the sameTPC Spec rating. This way, yourvehicle will continue to have tiresthat are designed to give thesame performance and vehiclesafety, during normal use, as theoriginal tires.

GM’s exclusive TPC Specsystem considers over a dozencritical specifications that impactthe overall performance of yourvehicle, including brake systemperformance, ride and handling,traction control, and tire pressuremonitoring performance. GM’sTPC Spec number is moldedonto the tire’s sidewall near thetire size. If the tires have anall-season tread design, the TPCSpec number will be followed byan MS for mud and snow. SeeTire Sidewall Labeling onpage 5-38 for additionalinformation.

GM recommends replacing tiresin sets of four. This is becauseuniform tread depth on all tireswill help keep your vehicleperforming most like it did whenthe tires were new. Replacingless than a full set of tires canaffect the braking and handlingperformance of your vehicle.

Uniform Tire QualityGradingQuality grades can be foundwhere applicable on the tiresidewall between tread shoulderand maximum section width.For example:

Treadwear 200 Traction AATemperature A

The following information relatesto the system developed by theUnited States National HighwayTraffic Safety Administration(NHTSA), which grades tires bytreadwear, traction, andtemperature performance. Thisapplies only to vehicles sold inthe United States. The gradesare molded on the sidewalls ofmost passenger car tires. TheUniform Tire Quality Grading(UTQG) system does not apply todeep tread, winter-type snowtires, space-saver, or temporaryuse spare tires, tires with nominal

rim diameters of 10 to 12 inches(25 to 30 cm), or to somelimited-production tires.

While the tires available onGeneral Motors passenger carsand light trucks may vary withrespect to these grades, theymust also conform to federalsafety requirements andadditional General Motors TirePerformance Criteria (TPC)standards.

Treadwear

The treadwear grade is acomparative rating based on thewear rate of the tire when testedunder controlled conditions ona specified government testcourse. For example, a tiregraded 150 would wear one anda half (1.5) times as well on thegovernment course as a tiregraded 100. The relativeperformance of tires depends

upon the actual conditions oftheir use, however, and maydepart significantly from the normdue to variations in driving habits,service practices, and differencesin road characteristics andclimate.

Traction – AA, A, B, C

The traction grades, from highestto lowest, are AA, A, B, and C.Those grades represent the tire’sability to stop on wet pavementas measured under controlledconditions on specifiedgovernment test surfaces ofasphalt and concrete. A tiremarked C may have poor tractionperformance.

Temperature – A, B, C

The temperature grades areA (the highest), B, and C,representing the tire’s resistanceto the generation of heat and itsability to dissipate heat whentested under controlledconditions on a specified indoorlaboratory test wheel. Sustainedhigh temperature can cause thematerial of the tire to degenerateand reduce tire life, andexcessive temperature canlead to sudden tire failure. Thegrade C corresponds to a level ofperformance which all passengercar tires must meet under theFederal Motor Vehicle SafetyStandard No. 109. Grades Band A represent higher levels ofperformance on the laboratorytest wheel than the minimumrequired by law. It should benoted that the temperature gradefor this tire is established for a tire

that is properly inflated and notoverloaded. Excessive speed,underinflation, or excessiveloading, either separately or incombination, can cause heatbuildup and possible tire failure.

Wheel Alignment andTire BalanceThe tires and wheels on your vehiclewere aligned and balanced carefullyat the factory to give you the longesttire life and best overall performance.Adjustments to wheel alignment andtire balancing will not be necessaryon a regular basis. However, if younotice unusual tire wear or yourvehicle pulling to one side or theother, the alignment might need to bechecked. If you notice your vehiclevibrating when driving on a smoothroad, the tires and wheels mightneed to be rebalanced. See yourdealer/retailer for proper diagnosis.

Wheel ReplacementReplace any wheel that is bent,cracked, or badly rusted or corroded.If wheel nuts keep coming loose, thewheel, wheel bolts, and wheel nutsshould be replaced.

If a Tire Goes FlatIt is unusual for a tire to blowoutwhile you are driving, especially ifyou maintain the tires properly. SeeTires on page 5-37. If air goes out ofa tire, It is much more likely to leakout slowly. But if you should everhave a blowout, here are a few tipsabout what to expect and what to do:

If a front tire fails, the flat tire willcreate a drag that pulls the vehicletoward that side. Take your footoff the accelerator pedal and gripthe steering wheel firmly. Steer to

maintain lane position, and thengently brake to a stop well out ofthe traffic lane.

A rear blowout, particularly on acurve, acts much like a skid and mayrequire the same correction youwould use in a skid. In any rearblowout, remove your foot from theaccelerator pedal. Get the vehicleunder control by steering the wayyou want the vehicle to go. It may bevery bumpy and noisy, but you canstill steer. Gently brake to a stop, welloff the road if possible.

If a tire goes flat, avoid further tireand wheel damage by driving slowlyto a level place and stopping.

Appearance Care

Interior CleaningThe vehicle’s interior will continueto look its best if it is cleaned often.Although not always visible, dustand dirt can accumulate on theupholstery. Dirt can damage carpet,fabric, leather, and plastic surfaces.Regular vacuuming is recommendedto remove particles from theupholstery. It is important to keepthe upholstery from becoming andremaining heavily soiled. Soilsshould be removed as quickly aspossible. The vehicle’s interior mayexperience extremes of heat thatcould cause stains to set rapidly.

Lighter colored interiors mayrequire more frequent cleaning.Use care because newspapers andgarments that transfer color to homefurnishings may also transfer color tothe vehicle’s interior.

When cleaning the vehicle’s interior,only use cleaners specificallydesigned for the surfaces beingcleaned. Permanent damage mayresult from using cleaners onsurfaces for which they were notintended. Use glass cleaner onlyon glass. Remove any accidentalover-spray from other surfacesimmediately. To prevent over-spray,apply cleaner directly to the cleaningcloth.

Notice: Using abrasive cleanerswhen cleaning glass surfaces onthe vehicle, could scratch theglass and/or cause damage tothe rear window defogger. Whencleaning the glass on the vehicle,use only a soft cloth and glasscleaner.

Many cleaners contain solventsthat may become concentratedin the vehicle’s breathing space.

Before using cleaners, read andadhere to all safety instructionson the label. While cleaning thevehicle’s interior, maintain adequateventilation by opening the vehicle’sdoors and windows.

Dust may be removed from smallbuttons and knobs using a smallbrush with soft bristles.

Products that remove odors fromthe vehicle’s upholstery andclean the vehicle’s glass can beobtained from your dealer/retailer.

Do not clean the vehicle using:

• A knife or any other sharp objectto remove a soil from any interiorsurface.

• A stiff brush. It can cause damageto the vehicle’s interior surfaces.

• Heavy pressure or aggressiverubbing with a cleaning cloth. Useof heavy pressure can damagethe interior and does not improvethe effectiveness of soil removal.

• Laundry detergents ordishwashing soaps withdegreasers can leave residuethat streaks and attracts dirt.For liquid cleaners, about20 drops per gallon (3.78 L) ofwater is a good guide. Use onlymild, neutral-pH soaps.

• Too much cleaner that saturatesthe upholstery.

• Organic solvents such as naptha,alcohol, etc. that can damage thevehicle’s interior.

Fabric/CarpetUse a vacuum cleaner with asoft brush attachment frequentlyto remove dust and loose dirt.A canister vacuum with a beater barin the nozzle may only be used onfloor carpet and carpeted floor mats.For any soil, always try to remove itfirst with plain water or club soda.

Before cleaning, gently remove asmuch of the soil as possible usingone of the following techniques:

• For liquids: gently blot theremaining soil with a paper towel.Allow the soil to absorb into thepaper towel until no more can beremoved.

• For solid dry soils: remove asmuch as possible and thenvacuum.

To clean:

1. Saturate a lint-free, clean whitecloth with water or club soda.

2. Wring the cloth to remove excessmoisture.

3. Start on the outside edge of thesoil and gently rub toward thecenter. Continue cleaning, usinga clean area of the cloth eachtime it becomes soiled.

4. Continue to gently rub the soiledarea until the cleaning clothremains clean.

5. If the soil is not completelyremoved, use a mild soapsolution and repeat the cleaningprocess that was used withplain water.

If any of the soil remains, acommercial fabric cleaner or spotlifter may be necessary. When acommercial upholstery cleaner orspot lifter is to be used, test a smallhidden area for colorfastness first.If the locally cleaned area gives anyimpression that a ring formation mayresult, clean the entire surface.

After the cleaning process has beencompleted, a paper towel can beused to blot excess moisturefrom the fabric or carpet.

Recycled original equipment partsmay also be used for repair. Theseparts are typically removed fromvehicles that were total losses inprior crashes. In most cases, theparts being recycled are fromundamaged sections of the vehicle.A recycled original equipment GMpart, may be an acceptable choice tomaintain your vehicle’s originallydesigned appearance and safetyperformance, however, the history ofthese parts is not known. Such partsare not covered by your GM NewVehicle Limited Warranty, and anyrelated failures are not covered bythat warranty.

Aftermarket collision parts arealso available. These are madeby companies other than GM andmay not have been tested for yourvehicle. As a result, these partsmay fit poorly, exhibit prematuredurability/corrosion problems,and may not perform properly in

subsequent collisions. Aftermarketparts are not covered by your GMNew Vehicle Limited Warranty, andany vehicle failure related to suchparts are not covered by thatwarranty.

Repair FacilityWe recommend that you choose acollision repair facility that meetsyour needs before you ever needcollision repairs. Your dealer/retailermay have a collision repair centerwith GM-trained technicians andstate of the art equipment, or be ableto recommend a collision repaircenter that has GM-trainedtechnicians and comparableequipment.

Insuring Your VehicleProtect your investment in your GMvehicle with comprehensive andcollision insurance coverage. Thereare significant differences in thequality of coverage afforded byvarious insurance policy terms.

Many insurance policies providereduced protection to your GMvehicle by limiting compensationfor damage repairs by usingaftermarket collision parts. Someinsurance companies will notspecify aftermarket collision parts.When purchasing insurance, werecommend that you assure yourvehicle will be repaired with GMoriginal equipment collision parts.If such insurance coverage is notavailable from your current insurancecarrier, consider switching to anotherinsurance carrier.

If your vehicle is leased, the leasingcompany may require you to haveinsurance that assures repairs withGenuine GM Original EquipmentManufacturer (OEM) parts orGenuine Manufacturer replacementparts. Read your lease carefully, asyou may be charged at the end ofyour lease for poor quality repairs.

If a Crash OccursHere is what to do if you areinvolved in a crash.

• Check to make sure that you areall right. If you are uninjured,make sure that no one else inyour vehicle, or the other vehicle,is injured.

• If there has been an injury, callemergency services for help.Do not leave the scene of a crashuntil all matters have been takencare of. Move your vehicle only ifits position puts you in danger oryou are instructed to move it by apolice officer.

• Give only the necessary andrequested information to policeand other parties involved in thecrash. Do not discuss yourpersonal condition, mental frameof mind, or anything unrelated tothe crash. This will help guardagainst post-crash legal action.

• If you need roadside assistance,call GM Roadside Assistance.See Roadside AssistanceProgram on page 7-6 for moreinformation.

• If your vehicle cannot be driven,know where the towing servicewill be taking it. Get a card fromthe tow truck operator or writedown the driver’s name, theservice’s name, and the phonenumber.

• Remove any valuables from yourvehicle before it is towed away.Make sure this includes yourinsurance information andregistration if you keep theseitems in your vehicle.

• Gather the important informationyou will need from the otherdriver. Things like name, address,phone number, driver’s licensenumber, vehicle license plate,vehicle make, model and modelyear, Vehicle IdentificationNumber (VIN), insurancecompany and policy number, anda general description of thedamage to the other vehicle.

• If possible, call your insurancecompany from the scene of thecrash. They will walk you throughthe information they will need.If they ask for a police report,phone or go to the policedepartment headquarters the nextday and you can get a copy of thereport for a nominal fee. In somestates/provinces with “no fault”insurance laws, a report may notbe necessary. This is especiallytrue if there are no injuries andboth vehicles are driveable.

• Choose a reputable collisionrepair facility for your vehicle.Whether you select a dealer/retailer or a private collision repairfacility to fix the damage, makesure you are comfortable withthem. Remember, you will have tofeel comfortable with their work fora long time.

• Once you have an estimate, readit carefully and make sure youunderstand what work will beperformed on your vehicle. If youhave a question, ask for anexplanation. Reputable shopswelcome this opportunity.

Managing the Vehicle DamageRepair ProcessIn the event that your vehiclerequires damage repairs, GMrecommends that you take anactive role in its repair. If you have apre-determined repair facility ofchoice, take your vehicle there, orhave it towed there. Specify to thefacility that any required replacementcollision parts be original equipmentparts, either new Genuine GM partsor recycled original GM parts.Remember, recycled parts will notbe covered by your GM vehiclewarranty.

Insurance pays the bill for therepair, but you must live with therepair. Depending on yourpolicy limits, your insurancecompany may initially value therepair using aftermarket parts.

Discuss this with your repairprofessional, and insist on GenuineGM parts. Remember if your vehicleis leased you may be obligated tohave the vehicle repaired withGenuine GM parts, even if yourinsurance coverage does not paythe full cost.

If another party’s insurancecompany is paying for the repairs,you are not obligated to accepta repair valuation based onthat insurance company’s collisionpolicy repair limits, as you haveno contractual limits with thatcompany. In such cases, you canhave control of the repair andparts choices as long as cost stayswithin reasonable limits.

Vehicle DataRecording andPrivacyYour GM vehicle has a number ofsophisticated computers that recordinformation about the vehicle’sperformance and how it is driven.For example, your vehicle usescomputer modules to monitor andcontrol engine and transmissionperformance, to monitor theconditions for airbag deployment anddeploy airbags in a crash and, if soequipped, to provide antilock brakingto help the driver control the vehicle.These modules may store data tohelp your dealer/retailer technicianservice your vehicle. Some modulesmay also store data about how youoperate the vehicle, such as rate offuel consumption or average speed.These modules may also retain theowner’s personal preferences, suchas radio pre-sets, seat positions, andtemperature settings.

Event Data RecordersThis vehicle has an Event DataRecorder (EDR). The main purposeof an EDR is to record, in certaincrash or near crash-like situations,such as an airbag deployment orhitting a road obstacle, data that willassist in understanding how avehicle’s systems performed. TheEDR is designed to record datarelated to vehicle dynamics andsafety systems for a short period oftime, typically 30 seconds or less.The EDR in this vehicle is designedto record such data as:

• How various systems in yourvehicle were operating

• Whether or not the driver andpassenger safety belts werebuckled/fastened

• How far, if at all, the driver waspressing the accelerator and/orbrake pedal

• How fast the vehicle was traveling

This data can help provide a betterunderstanding of the circumstancesin which crashes and injuries occur.

Important: EDR data is recordedby your vehicle only if a non-trivialcrash situation occurs; no data isrecorded by the EDR under normaldriving conditions and no personaldata (e.g., name, gender, age,and crash location) is recorded.However, other parties, such as lawenforcement, could combine theEDR data with the type of personallyidentifying data routinely acquiredduring a crash investigation.

To read data recorded by an EDR,special equipment is required,and access to the vehicle or theEDR is needed. In addition tothe vehicle manufacturer, otherparties, such as law enforcement,that have the special equipment, canread the information if they haveaccess to the vehicle or the EDR.

The navigation system includes navigation and audiofunctions.

While entering the vehicle or when turning the vehicleoff, some DVD Map Disc noise is normal.

Keeping your eyes on the road and your mind on thedrive is important for safe driving. The navigation systemhas built-in features intended to help keep your eyeson the road and mind on the drive. Some features maybe disabled while driving. Note that these functionswill be grayed-out. A grayed-out function indicates it isnot available when the vehicle is moving.

All functions are available when the vehicle is parked.Do the following before driving:

• Become familiar with the navigation systemoperation, hard keys on the faceplate, andtouch-sensitive screen buttons of the navigationsystem.

• Set up the audio by presetting favorite stations,setting the tone, and adjusting the speakers.

• Set up the navigation features before beginningdriving, such as entering an address or a presetdestination.

• Set up your phone numbers in advance so they canbe called easily with the press of a single button ora single voice command (for navigation systemsequipped with phone capability).

{CAUTION:

Taking your eyes off the road too long or too oftenwhile using the navigation system could cause acrash resulting in injury or death to you or others.Focus your attention on driving.

You should always be alert and obey traffic and roadwaylaws and instructions, regardless of the guidance from thenavigation system. Because the navigation system usesstreet map information that does not include all trafficrestrictions or the latest road changes, it may suggestusing a road that is now closed for construction or a turnthat is prohibited by signs at the intersection. Because the

system uses limited information, you must alwaysevaluate whether following the system’s directions is safeand legal for the current conditions.

When the navigation system is turned on, a screen mayappear with the information below, and you mustread and acknowledge the information it contains.

{CAUTION:

Taking your eyes off the road for extended periodscould cause a crash resulting in injury or death toyou or others.

Global Positioning System (GPS)The navigation system determines the position of thevehicle by using satellite signals, various vehicle signals,and map data.

At times, other interferences such as the satellitecondition, road configuration, the condition of thevehicle and/or other circumstances can interfere withthe navigation system’s ability to determine the accurateposition of the vehicle.

The GPS shows the current position of the vehicle usingsignals sent by the GPS Satellites of the United StatesDepartment of Defense. When the vehicle is notreceiving signals from the satellites, a symbol appearson the map screen. Refer to Symbols on page 2-7.

This system may not be available or interferences mayoccur if any of the following is true:

• Signals are obstructed by tall buildings, trees, largetrucks, or a tunnel.

• Objects are located on the rear shelf of the vehicle.

• Satellites are being repaired or improved.

• After-market glass tinting has been applied to thevehicle’s rear windshield.

Notice: Do not apply after-market glass tinting tothe vehicle’s windows. Glass tinting interfereswith the system’s ability to receive GPS signals andcauses the system to malfunction. The windowmight have to be replaced to correct the problem.This would not be covered by the warranty.

For more information if the GPS is not functioningproperly, see If the System Needs Service on page 2-40and Problems with Route Guidance on page 2-40.
