G WARNINGDue to the high center of gravity, the vehiclemay start to skid and roll over in the event ofan abrupt steering maneuver and/or whenthe vehicle's speed is not adapted to the roadconditions. There is a risk of an accident.Always adapt your speed and driving style tothe vehicle's driving characteristics and to theprevailing road and weather conditions.

Utility vehicles have a significantly higher roll-over rate than other types of vehicles.Failure to operate this vehicle safely may resultin an accident, rollover of the vehicle, and severeor fatal injury.In a rollover crash, an unbelted person is signif-icantly more likely to die than a person wearinga seat belt.You and all vehicle occupants should alwayswear your seat belts.

Event data recordersThis vehicle is equipped with an event datarecorder (EDR). This vehicle is equipped with anevent data recorder (EDR). The main purpose ofan EDR is to record, in certain crash or nearcrash-like situations, such as an air bag deploy-ment or hitting a road obstacle, data that willassist in understanding how a vehicle's systemsperformed. The EDR is designed to record datarelated to vehicle dynamics and safety systemsfor a short period of time, typically 30 secondsor less.The EDR in this vehicle is designed to recordsuch data as:RHow various systems in your vehicle wereoperatingRWhether or not the driver and passengersafety belts were buckled/fastenedRHow far (if at all) the driver was depressing theaccelerator and/or brake pedal andRHow fast the vehicle was traveling.These data can help provide a better under-standing of the circumstances in which crashesand injuries occur. NOTE: EDRdata are recordedby your vehicle only if a non-trivial crash situa-tion occurs; no data are recorded by the EDRunder normal driving conditions and no personaldata (e.g. name, gender, age and crash location)are recorded. However, other parties, such aslaw enforcement could combine the EDR datawith the type of personally identifying data rou-tinely acquired during a crash investigation.Access to the vehicle and/or the EDR is neededto read data that is recorded by an EDR, and

Occupant safety

Introduction to the restraint systemThe restraint system can reduce the risk of vehi-cle occupants coming into contact with parts ofthe vehicle's interior in the event of an accident.The restraint system can also reduce the forcestowhich vehicle occupants are subjected duringan accident.The restraint system comprises:Rseat belt systemRair bagsRchild restraint systemRchild seat securing systemsThe components of the restraint system work inconjunction with each other. They can onlydeploy their protective function if, at all times, allvehicle occupants:Rhave fastened their seat belts correctly(Y page 44)Rhave adjusted their seat and head restraintproperly (Y page 94).

As the driver, you also have to make sure thatthe steering wheel is adjusted correctly.Observe the information relating to the correctdriver's seat position (Y page 94).You also have to make sure that an air bag caninflate properly if deployed (Y page 46).An air bag supplements a correctly worn seatbelt. As an additional safety device, the air bagincreases the level of protection for vehicleoccupants in the event of an accident. For exam-ple, if, in the event of an accident, the protectionoffered by the seat belt is sufficient, the air bagsare not deployed.When an accident occurs, onlythe air bags that increase protection in that par-ticular accident situation are deployed. How-ever, seat belts and air bags generally do notprotect against objects penetrating the vehiclefrom the outside.Information on restraint system operation canbe found under "Triggering of the EmergencyTensioning Devices and air bags" (Y page 53).For information on children traveling with you inthe vehicle and on child restraint systems, see"Children in the vehicle" (Y page 57).

Important safety notes

G WARNINGModifications to the restraint system maycause it to no longer work as intended. Therestraint system may then not perform itsintended protective function andmay fail in anaccident or trigger unexpectedly, for example.This poses an increased risk of injury or evenfatal injury.Never modify parts of the restraint system.Never tamper with the wiring, the electroniccomponents or their software.If it is necessary to modify components of therestraint system to accommodate a personwith disabilities, contact an authorizedMercedes-Benz Center for details. USA only:for further information contact our CustomerAssistance Center at 1-800-FOR-MERCedes(1‑800‑367‑6372).

Mercedes-Benz recommends that you only usedriving aids which have been approved specifi-cally for your vehicle by Mercedes-Benz.

Restraint system warning lampThe functions of the restraint system arechecked after the ignition is switched on and atregular intervals while the engine is running.Therefore, malfunctions can be detected ingood time.The 6 restraint system warning lamp in theinstrument cluster lights up when the ignition isswitched on. It goes out no later than a few sec-onds after the vehicle is started. The compo-nents of the restraint system are in operationalreadiness.Amalfunction has occurred if the 6 restraintsystem warning lamp:Rdoes not light up after the ignition is switchedonRdoes not go out after a few seconds with theengine runningRlights up again while the engine is running

G WARNINGIf the restraint system is malfunctioning,restraint system components may be trig-gered unintentionally or may not deploy asintended during an accident. This can affectfor example the Emergency TensioningDevice or the air bag. This poses an increasedrisk of injury or even fatal injury.Have the restraint system checked andrepaired in a qualified specialist workshop assoon as possible.

PASSENGER AIR BAG indicator lamp

PASSENGER AIR BAG ON indicator lamp: andPASSENGER AIR BAGOFF indicator lamp; arepart of the Occupant Classification System(OCS).

The indicator lamps display the status of thefront-passenger front air bag.RPASSENGER AIR BAG ON lights up for 60 sec-onds, subsequently both indicator lamps areoff (PASSENGER AIR BAG ON and OFF): thefront-passenger front air bag is able to deployin the event of an accident.RPASSENGER AIR BAGOFF lights up: the front-passenger front air bag is deactivated. It willthen not be deployed in the event of an acci-dent.

If the PASSENGER AIR BAG ON indicator lamp isoff, only the PASSENGER AIR BAG OFF indicatorlamp shows the status of the front-passengerfront air bag. The PASSENGER AIR BAG OFFindicator lamp may be lit continuously or be off.Depending on the person in the front-passengerseat, the front-passenger front air bag musteither be deactivated or enabled; see the fol-lowing points. You must make sure of this bothbefore and during a journey.RChildren in a child restraint system:whether the front-passenger front air bag isenabled or deactivated depends on the instal-led child restraint system, and the age andsize of the child. Therefore, be sure to observethe notes on the "Occupant ClassificationSystem (OCS)" (Y page 48) and on "Chil-dren in the vehicle" (Y page 57). There youwill also find instructions on rearward andforward-facing child restraint systems on thefront-passenger seat.RAll other persons: depending on the classi-fication of the person in the front-passengerseat, the front-passenger front air bag is ena-bled or deactivated (Y page 48). Be sure toobserve the notes on "Seatbelts“ (Y page 42) and "Air bags"(Y page 46). There you can also find infor-mation on the correct seat position.

Seat belts

IntroductionSeat belts are the most effective means ofrestricting the movement of vehicle occupantsin the event of an accident or the vehicle rollingover. This reduces the risk of vehicle occupantscoming into contact with parts of the vehicleinterior or being ejected from the vehicle. Fur-thermore, the seat belt helps to keep the vehicle

occupant in the best position in relation to theair bag.The seat belt system comprises:RSeat beltsREmergency Tensioning Devices for the frontseat belts and the outer seat belts in the sec-ond row of seats as well as the seat belts inthe third rowRSeat belt force limiters for the front seat beltsand the outer seat belts in the second row ofseats as well as the seat belts in the third row

If the seat belt is pulled out of the belt outletquickly or with a jerky movement, the beltretractor locks. The belt strap cannot be extrac-ted any further.The Emergency Tensioning Device tightens theseat belt in an accident, pulling the belt closeagainst the body. However it does not pull thevehicle occupant back in the direction of thebackrest.The Emergency Tensioning Device does not cor-rect an incorrect seat position or the routing ofan incorrectly fastened seat belt.When triggered, a seat belt force limiter helps toreduce the force exerted by the seat belt on thevehicle occupant.The seat belt force limiters for the front seats aresynchronized with the front air bags, whichabsorb part of the deceleration force. This canreduce the force exerted on the vehicle occu-pants during an accident.

! If the front-passenger seat is unoccupied,do not insert the belt tongue into the buckle ofthe front-passenger seat. This may otherwiselead to the triggering of the Emergency Ten-sioning Device in the event of an accident,which will then need to be replaced.

Important safety notesThe use of seat belts and child restraint systemsis required by law in:Rall 50 statesRthe U.S. territoriesRthe District of ColumbiaRall Canadian provincesEvenwhere this is not required by law, all vehicleoccupants should correctly fasten their seatbelts before starting the journey.

G WARNINGIf the seat belt is not worn correctly, it cannotperform its intended protective function. Anincorrectly fastened seat belt can also causeinjuries, for example, in the event of an acci-dent or when braking or changing directionabruptly. This poses an increased risk of injuryor even fatal injury.Always ensure that all vehicle occupants havetheir seat belts fastened correctly and are sit-ting properly.

G WARNINGThe seat belt does not offer the intended levelof protection if you have not moved the back-rest to an almost vertical position.When brak-ing or in the event of an accident, you couldslide underneath the seat belt and sustainabdomen or neck injuries, for example. Thisposes an increased risk of injury or even fatalinjury.Adjust the seat properly before beginningyour journey. Always ensure that the backrestis in an almost vertical position and that theshoulder section of your seat belt is routedacross the center of your shoulder.

G WARNINGPersons less than 5 ft (1.50 m) tall cannotwear the seat belt correctly without an addi-tional and suitable restraint system. If theseat belt is not worn correctly, it cannot per-form its intended protective function. Anincorrectly fastened seat belt can also causeinjuries, for example, in the event of an acci-dent or when braking or changing directionabruptly. This poses an increased risk of injuryor even fatal injury.For this reason, always secure persons under5 ft (1.50m) tall in suitable additional restraintsystems.

If a child younger than twelve years old andunder 5 ft (1.50 m) in height is traveling in thevehicle:Ralways secure the child in a child restraintsystem suitable for this Mercedes-Benz vehi-

G WARNINGThe seat belts may not perform their intendedprotective function if:Rthey are damaged, modified, extremelydirty, bleached or dyedRthe seat belt buckle is damaged orextremely dirtyRthe Emergency Tensioning Devices, beltanchorages or inertia reels have beenmodi-fied.

Seat belts may be damaged in an accident,although the damage may not be visible, e.g.due to splinters of glass.Modified or damagedseat belts may tear or fail, e.g. in an accident.Modified Emergency Tensioning Devicescould accidentally trigger or fail to deploywhen necessary. This poses an increased riskof injury or even fatal injury.Never modify the seat belts, Emergency Ten-sioning Devices, belt anchorages and inertiareels. Make sure that the seat belts areundamaged, not worn out and clean. Follow-ing an accident, have the seat belts checkedimmediately at a qualified specialist work-shop.

Only use seat belts that have been approved foryour vehicle by Mercedes-Benz.

Proper use of the seat beltsObserve the safety notes on the seat belt(Y page 43).All vehicle occupants must be wearing the seatbelt correctly before beginning the journey. Alsomake sure that all vehicle occupants are alwayswearing the seat belt correctly while the vehicleis in motion.

When fastening the seat belt, always make surethat:Rthe seat belt tongue is only inserted to the beltbuckle belonging to that seat.Rthe seat belt is tight across your body.Avoid wearing bulky clothing, e.g. a wintercoat.Rthe seat belt is not twisted.Only then can the forces which occur be dis-tributed over the area of the belt.Rthe shoulder section of the belt is alwaysrouted across the center of your shoulder.The shoulder section of the belt must notcome into contact with your neck or be routedunder your arm. Where possible, adjust theseat belt to the appropriate height.Rthe lap belt passes tightly and as low down aspossible across your lap.The lap belt must always be routed acrossyour hip joints and not across your abdomen.This applies particularly to pregnant women.If necessary, push the lap belt down to yourhip joint and pull it tight using the shouldersection of the belt.Rthe seat belt is not routed across sharp, poin-ted or fragile objects.If you have such items located on or in yourclothing, e.g. pens, keys or eyeglasses, storethese in a suitable place.Ronly one person is using a seat belt at a time.Infants and children must never travel sittingon the lap of a vehicle occupant. In the eventof an accident, they could be crushedbetween the vehicle occupant and seat belt.Robjects are never secured with a seat belt ifthe seat belt is also being used by one of thevehicle's occupants.Also ensure that there are never objectsbetween a person and the seat, e.g. cushions.

Seat belts are only intended to secure andrestrain vehicle occupants. Always observe the"Loading guidelines" for securing objects, lug-gage or loads (Y page 294).

Air bags

IntroductionThe installation point of an air bag can be rec-ognized by the AIR BAG symbol.An air bag complements the correctly fastenedseat belt. It is no substitute for the seat belt. Theair bag provides additional protection in appli-cable accident situations.Not all air bags are deployed in an accident. Thedifferent air bag systems function independ-ently from one another (Y page 53).However, no system available today can com-pletely eliminate injuries and fatalities.It is also not possible to rule out a risk of injurycaused by an air bag due to the high speed atwhich the air bag must be deployed.

Important safety notes

G WARNINGIf you do not sit in the correct seat position,the air bag cannot protect as intended andcould even cause additional injury whendeployed. This poses an increased risk ofinjury or even fatal injury.To avoid hazardous situations, always makesure that all of the vehicle's occupants:Rhave fastened their seat belts correctly,including pregnant womenRare sitting correctly andmaintain the great-est possible distance to the air bagsRfollow the following instructionsAlways make sure that there are no objectsbetween the air bag and the vehicle's occu-pants.

RAdjust the seats properly before beginningyour journey. Always make sure that the seatis in an almost upright position. The center of

the head restraint must support the head atabout eye level.RMove the driver's and front-passenger seatsas far back as possible. The driver's seat posi-tionmust allow the vehicle to be driven safely.ROnly hold the steering wheel on the outside.This allows the air bag to be fully deployed.RAlways lean against the backrest while driv-ing. Do not lean forwards or lean against thedoor or side window. Youmay otherwise be inthe deployment area of the air bags.RAlways keep your feet in the footwell in frontof the seat. Do not put your feet on the dash-board, for example. Your feet may otherwisebe in the deployment area of the air bag.RFor this reason, always secure persons lessthan 5 ft (1.50 m) tall in suitable restraint sys-tems. Up to this height, the seat belt cannotbe worn correctly.

If a child is traveling in your vehicle, alsoobserve the following notes:RAlways secure children under twelve years ofage and less than 5 ft (1.50 m) tall in suitablechild restraint systems.RChild restraint systems should be installed onthe rear seats.ROnly secure a child in a rearward-facing childrestraint system on the front-passenger seatwhen the front-passenger front air bag isdeactivated. If the PASSENGER AIR BAG OFFindicator lamp is permanently lit, the front-passenger front air bag is deactivated(Y page 42).RAlways observe the instructions and safetynotes on the "Occupant Classification System(OCS)" (Y page 48) and on "Children in thevehicle" (Y page 57) in addition to the childrestraint system manufacturer's installationand operating instructions.

Objects in the vehicle interior may preventan air bag from functioning correctly. Beforestarting your journey and to avoid risks resultingfrom the speed of the air bag as it deploys, makesure that:Rthere are no people, animals or objectsbetween the vehicle occupants and an airbag.Rthere are no objects between the seat, doorand B-pillar.Rno hard objects, e.g. coat hangers, hang onthe grab handles or coat hooks.

Rno accessories, such as cup holders, areattached to the vehicle within the deploymentarea of an air bag, e.g. to doors, side windows,rear side trim or side walls.Rno heavy, sharp-edged or fragile objects are inthe pockets of your clothing. Store suchobjects in a suitable place.

G WARNINGIf you modify the air bag cover or affix objectssuch as stickers to it, the air bag can no longerfunction correctly. There is an increased riskof injury.Never modify an air bag cover or affix objectsto it.

G WARNINGSensors to control the air bags are located inthe doors. Modifications or work not per-formed correctly to the doors or door panel-ing, as well as damaged doors, can lead to thefunction of the sensors being impaired. The airbags might therefore not function properlyanymore. Consequently, the air bags cannotprotect vehicle occupants as they aredesigned to do. There is an increased risk ofinjury.Never modify the doors or parts of the doors.Always have work on the doors or door pan-eling carried out at a qualified specialist work-shop.

Front air bags! Do not place heavy objects on the front-passenger seat. This could cause the systemto identify the seat as being occupied. In theevent of an accident, the restraint systems onthe front-passenger side may be triggeredand have to be replaced.

Driver's air bag: deploys in front of the steer-ing wheel. Front-passenger front air bag;deploys in front of and above the glove box.When deployed, the front air bags offer addi-tional head and thorax protection for the occu-pants in the front seats.The PASSENGER AIR BAG OFF indicator lampinforms you about the status of the front-passenger front air bag (Y page 42).The front-passenger front air bag will onlydeploy if:Rthe system, based on the OCS weight sensorreadings, detects that the front-passengerseat is occupied (Y page 48).

Side impact air bags

G WARNINGUnsuitable seat covers can obstruct or pre-vent deployment of the air bags integratedinto the seats. Consequently, the air bagscannot protect vehicle occupants as they aredesigned to do. In addition, the operation ofthe occupant classification system (OCS)could be adversely affected. This poses anincreased risk of injury or even fatal injury.You should only use seat covers that havebeen approved for the respective seat byMercedes-Benz.

Front side impact air bags: and second rowrear side impact air bags; deploy next to theouter bolster of the seat backrest.When deployed, the side impact air bag offersadditional thorax protection. It also offers addi-tional pelvis protection for occupants in thefront seats. However, it does not protect the:RheadRneckRarmsIn the event of a side impact, the side impact airbag is deployed on the side on which the impactoccurs.The side impact air bag on the front-passengerside deploys under the following conditions:Rthe OCS system detects that the front-passenger seat is occupied orRthe belt tongue is engaged in the belt buckleof the front-passenger seat

If the belt tongue is engaged in the belt buckle,the side impact air bag on the front-passengerside deploys if an appropriate accident situationoccurs. In this case, deployment is independent

of whether the front-passenger seat is occupiedor not.

Window curtain air bags

Window curtain air bags: are integrated intothe side of the roof frame and deploy in the areaextending from the front door (A-pillar) to therear side window (D-pillar).When deployed, the window curtain air bagenhances the level of protection for the head.However, it does not protect the chest or arms.In the event of a side impact, the window curtainair bag is deployed on the side on which theimpact occurs.If the system determines that they can offeradditional protection to that provided by theseat belt, a window curtain air bag may bedeployed in other accident situations(Y page 53).

Occupant Classification System(OCS)

IntroductionThe Occupant Classification System (OCS) cat-egorizes the person in the front-passenger seat.Depending on that result, the front-passengerfront air bag is either enabled or deactivated.The system does not deactivate:Rthe side impact air bagRthe window curtain air bagRthe Emergency Tensioning Devices

In the following situation, the side impact air bagand the Emergency Tensioning Device are deac-tivated:ROCS has not categorized the person on thefront-passenger seat as an adult or a personof corresponding stature andRthe seat belt tongue of the seat belt is notinserted into the front-passenger seat beltbuckle

RequirementsTo be classified correctly, the front passengermust sit:Rwith the seat belt fastened correctlyRin an almost upright position with their backagainst the seat backrestRwith their feet resting on the floor, if possibleIf the front passenger does not observe theseconditions, OCS may produce a false classifica-tion, e.g. because the front passenger:Rtransfers their weight by supporting them-selves on a vehicle armrestRsits in such a way that their weight is raisedfrom the seat cushion

If it is absolutely necessary to install a childrestraint system on the front-passenger seat, besure to observe the correct positioning of thechild restraint system. Never place objectsunder or behind the child restraint system, e.g. acushion. The entire base of the child restraintsystem must always rest on the seat cushion ofthe front-passenger seat. The backrest of theforward-facing child restraint systemmust lie asflat as possible against the backrest of the front-passenger seat.The child restraint system must not touch theroof or be subjected to a load by the headrestraint. Adjust the angle of the seat backrestand the head restraint position accordingly.Only then can OCS be guaranteed to functioncorrectly. Always observe the child restraint sys-tem manufacturer's installation and operatinginstructions.

G WARNINGIf the PASSENGER AIR BAG OFF indicatorlamp is lit, the front-passenger front air bag isdisabled. It will not be deployed in the event ofan accident and cannot perform its intendedprotective function. A person in the front-passenger seat could then, for example, comeinto contact with the vehicle's interior, espe-cially if the person is sitting too close to thedashboard. This poses an increased risk ofinjury or even fatal injury.When the front-passenger seat is occupied,always ensure that:Rthe classification of the person in the front-passenger seat is correct and the front-passenger front air bag is enabled or disa-bled in accordance with the person in thefront-passenger seatRthe front-passenger seat has been movedback as far back as possible.Rthe person is seated correctly.Make sure, both before and during the jour-ney, that the status of the front-passengerfront air bag is correct.

G WARNINGIf you secure a child in a rearward-facing childrestraint system on the front-passenger seatand the PASSENGER AIR BAG OFF indicatorlamp is off, the front-passenger front air bagmay deploy in the event of an accident. Thechild could be struck by the air bag. This posesan increased risk of injury or even fatal injury.Make sure that the front-passenger front airbag has been disabled. The PASSENGER AIRBAG OFF indicator lamp must be lit.

If the PASSENGER AIR BAG OFF indicator lampstays off, do not install a rearward-facing childrestraint system on the front-passenger seat.You can find more information on OCS under"Problemswith theOccupant Classification Sys-tem" (Y page 52).

G WARNINGIf you secure a child in a forward-facing childrestraint system on the front-passenger seatand you position the front-passenger seat tooclose to the dashboard, the child could, in theevent of an accident:Rcome into contact with the vehicle's inte-rior if the PASSENGER AIR BAG OFF indi-cator lamp is lit, for exampleRbe struck by the air bag if the PASSENGERAIR BAG OFF indicator lamp is off

This poses an increased risk of injury or evenfatal injury.Move the front-passenger seat as far back aspossible. Always make sure that the shoulderbelt strap is correctly routed from the vehiclebelt sash guide to the shoulder belt guide onthe child restraint system. The shoulder beltstrap must be routed forwards and down-wards from the vehicle belt sash guide. If nec-essary, adjust the vehicle belt sash guide andthe front-passenger seat accordingly. Alwaysobserve the child restraint system manufac-turer's installation instructions.

If OCS determines that:Rthe front-passenger seat is unoccupied, thePASSENGER AIR BAG OFF indicator lamplights up after the system self-test andremains lit. This indicates that the front-passenger front air bag is deactivated.Rthe front-passenger seat is occupied by achild of up to twelvemonths old, in a standardchild restraint system, the PASSENGER AIRBAG OFF indicator lamp lights up after thesystem self-test and remains lit. This indi-cates that the front-passenger front air bag isdeactivated.But even in the case of a twelve-month-oldchild, in a standard child restraint system, thePASSENGER AIR BAG OFF indicator lamp cango out after the system self-test. This indi-cates that the front-passenger front air bag isactivated. The result of the classification isdependent on, among other factors, the childrestraint system and the child's stature. It isrecommended that you install the childrestraint system on a suitable rear seat.

repaired. This will help to make sure the air bagscontinue to perform their protective function forthe vehicle occupants in the event of a crash.

G WARNINGEmergency Tensioning Devices that havedeployed pyrotechnically are no longer opera-tional and are unable to perform their inten-ded protective function. This poses anincreased risk of injury or even fatal injury.Have pyrotechnically triggered EmergencyTensioning Devices replaced immediately at aqualified specialist workshop.

An electric motor is used by PRE-SAFE® to trig-ger the tightening of the seat belt in hazardoussituations. This procedure is reversible.If Emergency Tensioning Devices are triggeredor air bags are deployed, you will hear a bang,and a small amount of powder may also bereleased. The 6 restraint system warninglamp lights up.Only in rare cases will the bang affect your hear-ing. The powder that is released generally doesnot constitute a health hazard, but it may causeshort-term breathing difficulties in people withasthma or other respiratory problems. Providedit is safe to do so, you should leave the vehicleimmediately or open the window in order to pre-vent breathing difficulties.Air bags and pyrotechnic Emergency TensioningDevices (ETDs) contain perchlorate material,which may require special handling and regardfor the environment. National guidelines mustbe observed during disposal. In California, seewww.dtsc.ca.gov/HazardousWaste/Perchlorate/index.cfm.

Method of operationDuring the first stage of a collision, the restraintsystem control unit evaluates important physi-cal data relating to vehicle deceleration or accel-eration, such as:RdurationRdirectionRintensityBased on the evaluation of this data, therestraint system control unit triggers the Emer-gency Tensioning Devices during a frontal orrear collision.

An Emergency Tensioning Device can only betriggered, if:Rthe ignition is switched onRthe components of the restraint system areoperational. You can find further informationunder: "Restraint system warning lamp"(Y page 42)Rthe belt tongue is engaged in the buckle onthe respective front-passenger seat

The Emergency Tensioning Devices in the rearcompartment are triggered independently of thelock status of the seat belts.If the restraint system control unit detects amore severe accident, further components ofthe restraint system are activated independ-ently of each other in certain frontal collisionsituations:RFront air bags and driver's knee bagRWindow curtain air bag, if the system deter-mines that deployment can offer additionalprotection to that provided by the seat belt

The front-passenger front air bag is activated ordeactivated depending on the person on thefront-passenger seat. The front-passenger frontair bag can only deploy in an accident if thePASSENGER AIR BAG OFF indicator lamp is off.Observe the information on the PASSENGERAIRBAG indicator lamps (Y page 42).Your vehicle has two-stage front air bags. Duringthe first deployment stage, the front air bag isfilled with propellant gas to reduce the risk ofinjuries. The front air bag is fully deployed withthe maximum amount of propellant gas if a sec-ond deployment threshold is reached within afew milliseconds.The activation threshold of the Emergency Ten-sioning Devices and the air bag are determinedby evaluating the rate of vehicle deceleration oracceleration which occurs at various points inthe vehicle. This process is pre-emptive innature. Deployment should take place in goodtime at the start of the collision.The rate of vehicle deceleration or accelerationand the direction of the force are essentiallydetermined by:Rthe distribution of forces during the collisionRthe collision angleRthe deformation characteristics of the vehicleRthe characteristics of the object with whichthe vehicle has collided

Factors which can only be seen and measuredafter a collision has occurred do not play a deci-

PRE-SAFE® (anticipatory occupantprotection system)

IntroductionIn certain hazardous situations, PRE-SAFE®takes pre-emptivemeasures to protect the vehi-cle occupants.

Important safety notes! Make sure that there are no objects in thefootwell or behind the seats. There is a dangerthat the seats and/or objects could be dam-aged when PRE-SAFE® is activated.

Although your vehicle is equipped with PRE-SAFE®, the possibility of injury in the event of anaccident cannot be ruled out. Always adapt yourdriving style to suit the prevailing road andweather conditions andmaintain a safe distancefrom the vehicle in front. Drive carefully.

FunctionPRE-SAFE® intervenes:Rin emergency braking situations, e.g. whenBAS is activatedRin critical driving situations, e.g. when physi-cal limits are exceeded and the vehicle under-steers or oversteers severelyRon vehicles with the Driving Assistance pack-age: if BAS PLUS intervenes powerfully or theradar sensor system detects an imminentdanger of collision in certain situations

PRE-SAFE® takes the following measuresdepending on the hazardous situation detected:Rthe front seat belts are pre-tensioned.Rif the vehicle skids, the side windows and thesliding sunroof are closed.

Rvehicles with the memory function: the front-passenger seat is adjusted if it is in an unfav-orable position.Rvehicleswith amulticontour seat: the air pres-sure in the side bolsters of the seat backrestis increased.

If the hazardous situation passes without result-ing in an accident, PRE-SAFE® slackens the beltpre-tensioning. On vehicles with multicontourseats, the air pressure in the side bolsters isreduced again. All settings made by PRE-SAFE®can then be reversed.If the seat belt pre-tensioning is not reduced:X Move the seat backrest or seat back slightlywhen the vehicle is stationary.The seat belt pre-tensioning is reduced andthe locking mechanism is released.

The seat-belt adjustment is an integral part ofthe PRE-SAFE® convenience function. Informa-tion about the convenience function can befound under "Belt adjustment" (Y page 45).

PRE-SAFE® PLUS (anticipatory occu-pant protection system PLUS)

IntroductionPRE-SAFE® PLUS is only available in vehicleswith the Driving Assistance package.Using the radar sensor system, PRE-SAFE®PLUS is able to detect that a head-on or rear-endcollision is imminent. In certain hazardous sit-uations, PRE-SAFE® PLUS takes pre-emptivemeasures to protect the vehicle occupants.

Important safety notesThe intervention of PRE-SAFE® PLUS cannotprevent an imminent collision.The driver is not warned about the interventionof PRE-SAFE® PLUS.PRE-SAFE® PLUS does not intervene if the vehi-cle is backing up.When driving, or when parking or exiting a park-ing space with assistance from Parking Pilot,PRE-SAFE® PLUS will not apply the brakes.

FunctionPRE-SAFE® PLUS intervenes in certain situa-tions if the radar sensor system detects animminent head-on or rear-end collision.PRE-SAFE® PLUS takes the following measuresdepending on the hazardous situation detected:Rif the radar sensor system detects that ahead-on collision is imminent, the seat beltsare pre-tensioned.Rif the radar sensor system detects that a rear-end collision is imminent:- the brake pressure is increased if the driverapplies the brakes when the vehicle is sta-tionary.

Children in the vehicle

Important safety notesAccident statistics show that children securedin the rear seats are safer than children securedin the front-passenger seat. For this reason,Mercedes-Benz strongly advises that you installa child restraint system on a rear seat. Childrenare generally better protected there.If a child younger than twelve years old andunder 5 ft (1.50 m) in height is traveling in thevehicle:Ralways secure the child in a child restraintsystem suitable for Mercedes-Benz vehicles.The child restraint system must be appropri-ate to the age, weight and size of the childRbe sure to observe the instructions and safetynotes in this section in addition to the childrestraint system manufacturer's installationinstructionsRbe sure to observe the instructions and safetynotes on the "Occupant classification system(OCS)" (Y page 48)

G WARNINGIf you leave children unsupervised in the vehi-cle, they could set it inmotion by, for example:Rrelease the parking brake.Rshift the automatic transmission out of theparking position P.Rstart the engine.In addition, they may operate vehicle equip-ment and become trapped. There is a risk ofan accident and injury.When leaving the vehicle, always take theSmartKeywith you and lock the vehicle. Neverleave children unsupervised in the vehicle.

G WARNINGIf persons, particularly children are subjectedto prolonged exposure to extreme heat orcold, there is a risk of injury, possibly evenfatal. Never leave children unattended in thevehicle.

G WARNINGIf the child restraint system is subjected todirect sunlight, parts may get very hot. Chil-

dren may burn themselves on these parts,particularly on the metal parts of the childrestraint system. There is a risk of injury.If you leave the vehicle, taking the child withyou, always ensure that the child restraintsystem is not exposed to direct sunlight. Pro-tect it with a blanket, for example. If the childrestraint system has been exposed to directsunlight, let it cool down before securing thechild in it. Never leave children unattended inthe vehicle.

Always ensure that all vehicle occupants havetheir seat belts fastened correctly and are sittingproperly. Particular attention must be paid tochildren.Observe the safety notes on the seat belt(Y page 43) and the notes on correct use of seatbelts (Y page 44).A booster seat may be necessary to achieveproper seat belt positioning for children over41 lbs (18 kg) until they reach a height where athree-point seat belt can be properly fastenedwithout a booster seat.

Driving safety systems

Overview of driving safety systemsIn this section, you will find information aboutthe following driving safety systems:RABS (Anti-lock Braking System)(Y page 63)RBAS (Brake Assist System) (Y page 64)RActive Brake Assist (Y page 64)RESP® (Electronic Stability Program)(Y page 67)REBD (Electronic Brake force Distribution)(Y page 69)RADAPTIVE BRAKE (Y page 69)RActive Brake Assist with cross-traffic function(Y page 69)RSTEER CONTROL (Y page 72)

Important safety notesIf you fail to adapt your driving style or if you areinattentive, the driving safety systems can nei-ther reduce the risk of an accident nor overridethe laws of physics. Driving safety systems aremerely aids designed to assist driving. You areresponsible for maintaining the distance to thevehicle in front, for vehicle speed, for braking ingood time, and for staying in lane. Always adaptyour driving style to suit the prevailing road andweather conditions andmaintain a safe distancefrom the vehicle in front. Drive carefully.The driving safety systems described only workas effectively as possible when there is ade-quate contact between the tires and the roadsurface. Pay particular attention to the informa-tion regarding tires, recommended minimumtire tread depths etc. in the "Wheels and tires"section (Y page 346).In wintry driving conditions, always use wintertires (M+S tires) and if necessary, snow chains.Only in this way will the driving safety systemsdescribed in this section work as effectively aspossible.

ABS (Anti-lock Braking System)

General informationABS regulates brake pressure in such a way thatthe wheels do not lock when you brake. Thisallows you to continue steering the vehiclewhenbraking.The ! ABS warning lamp in the instrumentcluster lights up when the ignition is switchedon. It goes out when the engine is running.ABS works from a speed of about 5 mph(8 km/h), regardless of road-surface conditions.ABS works on slippery surfaces, even when youonly brake gently.

Important safety notesi Observe the "Important safety notes" sec-tion (Y page 63).

G WARNINGIf ABS is faulty, the wheels could lock whenbraking. The steerability and braking charac-teristics may be severely impaired. Addition-ally, further driving safety systems are deac-tivated. There is an increased danger of skid-ding and accidents.Drive on carefully. Have ABS checked imme-diately at a qualified specialist workshop.

When ABS is malfunctioning, other systems,including driving safety systems, will alsobecome inoperative. Observe the informationon the ABS warning lamp (Y page 277) and dis-play messages which may be shown in theinstrument cluster (Y page 245).

BrakingX If ABS intervenes: continue to depress thebrake pedal vigorously until the braking sit-uation is over.

X To make a full brake application: depressthe brake pedal with full force.

If ABS intervenes when braking, you will feel apulsing in the brake pedal.The pulsating brake pedal can be an indicationof hazardous road conditions, and functions as areminder to take extra care while driving.

Off-road ABSAn ABS system specifically suited to off-roadterrain is activated automatically once the off-road program is activated on:RVehicles without the Offroad Engineeringpackage (Y page 217)RVehicles with the Off-Road Engineering pack-age (Y page 218)

At speeds below 20 mph (30 km/h), the frontwheels lock cyclically during braking. The dig-ging-in effect achieved in the process reducesthe stopping distance on off-road terrain. Thislimits steering capability.

BAS (Brake Assist System)

General informationBAS operates in emergency braking situations.If you depress the brake pedal quickly, BASautomatically boosts the braking force, thusshortening the stopping distance.

Important safety notesi Observe the "Important safety notes" sec-tion (Y page 63).

G WARNINGIf BAS is malfunctioning, the braking distancein an emergency braking situation isincreased. There is a risk of an accident.In an emergency braking situation, depressthe brake pedal with full force. ABS preventsthe wheels from locking.

BrakingX Keep the brake pedal firmly depressed untilthe emergency braking situation is over.ABS prevents the wheels from locking.

The brakes will function as usual once yourelease the brake pedal. BAS is deactivated.

Active Brake Assist

General informationi Observe the "Important safety notes" sec-tion (Y page 63).

Active Brake Assist consists of a distance warn-ing function with an autonomous braking func-tion and Adaptive Brake Assist.Active Brake Assist can help you tominimize therisk of a collision with the vehicle traveling infront or reduce the effects of such a collision.If Active Brake Assist detects that there is a riskof collision, you will be warned visually andacoustically. If you do not react to the visual andaudible collision warning, autonomous brakingcan be initiated in critical situations. If you applythe brake yourself in a critical situation, Adap-tive Brake Assist of the Active Brake Assist sys-tem supports you.

Important safety notesIn particular, the detection of obstacles can beimpaired if:Rthere is dirt on the sensors or anything elsecovering the sensorsRthere is snow or heavy rainRthere is interference by other radar sourcesRthere are strong radar reflections, for exam-ple in parking garagesRa narrow vehicle is traveling in front, e.g. amotorbikeRa vehicle is traveling in front on a different lineRnew vehicles or after servicing is carried outon the Active Brake Assist systemObserve the notes in the section on breaking-in (Y page 137).

Following damage to the front end of the vehicle,have the configuration and operation of theradar sensor checked at a qualified specialistworkshop. This also applies to collisions at slowspeeds where there is no visible damage to thefront of the vehicle.

Activating/deactivatingActive Brake Assist is automatically active afterswitching on the ignition.You can activate or deactivate Active BrakeAssist (Y page 237) in the on-board computer.When deactivated, the distance warning func-

tion and the autonomous braking function arealso deactivated.If Active Brake Assist is deactivated, theæsymbol appears in the assistance graphic dis-play.If DSR (Y page 216) is activated, Active BrakeAssist is deactivated.

Distance warning function

General informationThe distance warning function can help you tominimize the risk of a front-end collision with avehicle ahead or reduce the effects of such acollision. If the distance warning functiondetects that there is a risk of a collision, you willbe warned visually and acoustically.

Important safety notesi Observe the "Important safety notes" sec-tion for driving safety systems (Y page 63).

G WARNINGThe distance warning function does not react:Rto people or animalsRto oncoming vehiclesRto crossing trafficRwhen corneringThus, the distance warning function cannotprovide a warning in all critical situations.There is a risk of an accident.Always pay careful attention to the traffic sit-uation and be ready to brake.

G WARNINGThe distance warning function cannot alwaysclearly identify objects and complex trafficsituations.In such cases, the distance warning functionmay:Rgive an unnecessary warningRnot give a warningThere is a risk of an accident.Always pay careful attention to the traffic sit-uation and do not rely solely on the distancewarning function.

FunctionStarting at a speed of around 4 mph (7 km/h),the distance warning function warns you if yourapidly approach a vehicle in front. An intermit-tent warning tone will then sound, and the·distance warning lamp will light up in the instru-ment cluster.X Brake immediately in order to increase thedistance from the vehicle in front.

orX Take evasive action, provided it is safe to doso.

Due to the nature of the system, particularlycomplicated but non-critical driving conditionsmay also cause the system to display a warning.With the help of the radar sensor system, thedistance warning function can detect obstaclesthat are in the path of your vehicle for an exten-ded period of time.Up to a speed of around 44 mph (70 km/h), thedistance warning function can also react to sta-tionary obstacles, such as stopped or parkedvehicles.

Autonomous braking functionIf the driver does not react to the distance warn-ing signal in a critical situation, Active BrakeAssist can assist the driver with the autonomousbraking function.The autonomous braking function is available inthe following speed ranges:R4 - 65 mph (7 - 105 km/h) for moving objectsR4 - 31 mph (7 - 50 km/h) for stationaryobjects

Due to the nature of the system, particularlycomplicated but non-critical driving conditionsmay also cause the Autonomous Braking Func-tion to intervene.If the autonomous braking function requires aparticularly high braking force, preventativepassenger protection measures (PRE-SAFE®)are activated simultaneously (Y page 55).

Adaptive Brake Assist

General informationi Observe the "Important safety notes" sec-tion (Y page 63).

With the help of adaptive Brake Assist, the dis-tance warning signal can detect obstacles that

are in the path of your vehicle for an extendedperiod of time.If adaptive Brake Assist detects a risk of colli-sion with the vehicle in front, it calculates thebraking force necessary to avoid a collision. Ifyou apply the brakes forcefully, adaptive BrakeAssist will automatically increase the brakingforce to a level suitable for the traffic conditions.Adaptive Brake Assist provides braking assis-tance in hazardous situations at speeds above4mph (7 km/h). It uses radar sensor technologyto assess the traffic situation.Up to a speed of approximately 155 mph(250 km/h), Adaptive Brake Assist is capable ofreacting to moving objects that have alreadybeen detected as such at least once over theperiod of observation.Up to a speed of approximately 44 mph(70 km/h), Adaptive Brake Assist reacts to sta-tionary obstacles.If adaptive Brake Assist demands particularlyhigh braking force, preventative passenger pro-tection measures (PRE-SAFE®) are activatedsimultaneously (Y page 55).X Keep the brake pedal depressed until theemergency braking situation is over.ABS prevents the wheels from locking.

The brakes will work normally again if:Ryou release the brake pedal.Rthere is no longer any danger of a collision.Rno obstacle is detected in front of your vehi-cle.

Adaptive Brake Assist is then deactivated.

Important safety notesi Observe the "Important safety notes" sec-tion for driving safety systems (Y page 63).

G WARNINGAdaptive Brake Assist cannot always clearlyidentify objects and complex traffic situa-tions.In such cases, Adaptive Brake Assist can:Rintervene unnecessarilyRnot interveneThere is a risk of an accident.Always pay careful attention to the traffic sit-uation and be ready to brake. Terminate theintervention in a non-critical driving situation.

G WARNINGAdaptive Brake Assist does not react:Rto people or animalsRto oncoming vehiclesRto crossing trafficRwhen corneringAs a result, the Adaptive Brake Assist may notintervene in all critical conditions. There is arisk of an accident.Always pay careful attention to the traffic sit-uation and be ready to brake.

Due to the nature of the system, particularlycomplicated but non-critical driving conditionsmay also cause Brake Assist to intervene.If adaptive Brake Assist is not available due to amalfunction in the radar sensor system, thebrake system remains available with full brakeboosting effect and BAS.

ESP® (Electronic Stability Program)

General notesi Observe the "Important safety notes" sec-tion (Y page 63).

ESP® monitors driving stability and traction, i.e.power transmission between the tires and theroad surface.If ESP® detects that the vehicle is deviating fromthe direction desired by the driver, one or morewheels are braked to stabilize the vehicle. Theengine output is also modified to keep the vehi-cle on the desired course within physical limits.ESP® assists the driver when pulling away onwet or slippery roads. ESP® can also stabilizethe vehicle during braking.

ETS/4ETS (Electronic Traction System)4ETS traction control is part of ESP®.Traction control brakes the drive wheels indi-vidually if they spin. This enables you to pullaway and accelerate on slippery surfaces, forexample if the road surface is slippery on oneside. In addition, more drive torque is transfer-red to the wheel or wheels with traction.Traction control remains active, even if youdeactivate ESP®.

Intelligent Light System

General notesThe Intelligent Light System is a system thatadjusts the headlamps automatically to suit theprevailing driving and weather conditions. Itoffers advanced functions for improved illumi-nation of the road surface, e.g. depending on thevehicle speed or weather conditions. The sys-tem includes the active light function, corneringlight function, highway mode and extendedrange fog lamps. The system is only active whenit is dark.You can activate or deactivate the "IntelligentLight System" using the on-board computer(Y page 239).

Active light functionThe active light function is a system that movesthe headlamps according to the steering move-ments of the front wheels. In this way, relevantareas remain illuminated while driving. Thisallows you to identify pedestrians, cyclists andanimals.Active: when the lights are switched on.

Cornering light functionThe cornering light function improves the illu-mination of the road over a wide angle in thedirection you are turning, enabling better visi-bility in tight bends, for example. It can only beactivated when the low-beam headlamps areswitched on.Active:Rif you are driving at speeds below 25 mph(40 km/h) and switch on the turn signal orturn the steering wheelRif you are driving at speeds between 25 mph(40 km/h) and 45 mph (70 km/h) and turnthe steering wheel

The cornering lamp may remain lit for a shorttime, but is automatically switched off after nomore than three minutes.

Highway modeHighwaymode increases the range of the beam.Active:if you are driving at a speed above110 km/h and do not make any large steeringmovements for at least 1,000 m or if you aredriving at a speed above 130 km/h.

Not active: if you are driving at speeds below80 km/h following activation.

Extended range fog lampsThe extended range fog lamps reduce the glareexperienced by the driver and improve the illu-mination of the edge of the road.Active: if you are driving at speeds below40 mph (70 km/h) and you switch on the rearfog lamp.Not active: if, following activation, you are driv-ing at speeds above 60mph (100 km/h) or if youswitch off the rear fog lamp

Off-road lightsThe off-road lights facilitate the early recogni-tion of objects/obstacles when driving off-roadthanks to a symmetrical, wider and brighter dis-tribution of light from the low-beam headlamps.Active: when driving at speeds no faster than30 mph (50 km/h) and the off-road programselector wheel is in position 1 or 2.Not active: when driving at speeds above30 mph (50 km/h).When the off-road lights are switched on, thecornering light function is permanently activa-ted, the active light function is deactivated andthe headlamp range control is set to staticmode.

Cornering light functionThe cornering light function improves the illu-mination of the road over a wide angle in thedirection you are turning, enabling better visi-bility in tight bends, for example. It can only beactivated when the low-beam headlamps areswitched on.Active:Rif you are driving at speeds below 25 mph(40 km/h) and switch on the turn signal orturn the steering wheelRif you are driving at speeds between 25 mph(40 km/h) and 45 mph (70 km/h) and turnthe steering wheel

The cornering lamp may remain lit for a shorttime, but is automatically switched off after nomore than three minutes.

Adaptive Highbeam Assist

General notesYou can use this function to set the headlampsto change between low beam and high beamautomatically. The system recognizes vehicleswith their lights on, either approaching from theopposite direction or traveling in front of yourvehicle, and consequently switches the head-lamps from high beam to low beam.The system automatically adapts the low-beamheadlamp range depending on the distance tothe other vehicle. Once the system no longerdetects any other vehicles, it reactivates thehigh-beam headlamps.The system's optical sensor is located behindthe windshield near the overhead control panel.

Important safety notes

G WARNINGAdaptive HighbeamAssist does not recognizeroad users:Rwho have no lights, e.g. pedestriansRwho have poor lighting, e.g. cyclistsRwhose lighting is blocked, e.g. by a barrierOn very rare occasions, Adaptive HighbeamAssist may fail to recognize other road usersthat have lights, or may recognize them toolate. In this, or in similar situations, the auto-matic high-beam headlamps will not be deac-tivated orwill be activated regardless. There isa risk of an accident.Always carefully observe the traffic conditionsand switch off the high-beam headlamps ingood time.

Adaptive Highbeam Assist cannot take intoaccount road, weather or traffic conditions.Adaptive HighbeamAssist is only an aid. You areresponsible for adjusting the vehicle's lightingto the prevailing light, visibility and traffic con-ditions.In particular, the detection of obstacles can beimpaired if:Rpoor visibility, e.g. due to fog, heavy rain orsnowRdirt on the sensors or the sensors areobscured

Overview of climate control systems

General notesObserve the settings recommended on the fol-lowing pages. The windows could otherwise fogup.To prevent the windows from fogging up:Rswitch off climate control only brieflyRswitch on air-recirculation mode only brieflyRswitch on the cooling with air dehumidifica-tion functionRswitch on the defrost windshield functionbriefly, if required

Climate control regulates the temperature andthe humidity in the vehicle interior and filtersundesirable substances out of the air.The residual heat function can only be activatedor deactivated with the ignition switched off(Y page 133).

i Ventilate the vehicle for a brief period duringwarm weather, e.g. using the convenienceopening feature (Y page 87).This will speed up the cooling process and thedesired interior temperature will be reachedmore quickly.

If you start the engine using your smartphone,the last selected climate control setting is reac-tivated (Y page 140).

i The integrated filter filters out most parti-cles of dust and soot and completely filtersout pollen. It also reduces gaseous pollutantsand odors. A clogged filter reduces theamount of air supplied to the vehicle interior.For this reason, you should always observethe interval for replacing the filter, which isspecified in the Maintenance Booklet. As itdepends on environmental conditions, e.g.heavy air pollution, the interval may beshorter than stated in the Maintenance Book-let.

i Vehicles with AIR-BALANCE package: inaddition to ionization, the vehicle has an airfilter with anti-allergenic properties that con-tribute to improved air filtration.

Thewindows could otherwise fog up,since no fresh air is drawn into the vehicle inair-recirculation mode.RVehicles with 3-zone climate control:usethe ZONE function to adopt the temperaturesettings on the driver's side for the front-passenger side and the rear compartment aswell. The indicator lamp above theá but-ton goes out.RVehicles with 3-zone climate control:usethe "residual heat" function if youwant to heator ventilate the vehicle interior when the igni-tion is switched off. The residual heat function

can only be activated or deactivated with theignition switched off.RIf you change the settings of the climate con-trol system, the climate status displayappears for approximately three seconds atthe bottom of the screen in the multimediasystem display. You will see the current set-tings of the various climate control functions.

During automatic engine switch-off, the climatecontrol system only operates at a reduced capa-city. If you require the full climate control output,you can switch off the ECO start/stop functionby pressing the ECO button (Y page 143).

Notes on breaking-in a new vehicle

Important safety notesThe sensor system of some driving and drivingsafety systems adjusts automatically while acertain distance is being driven after the vehiclehas been delivered or after repairs. Full systemeffectiveness is not reached until the end of thisteach-in procedure.New and replaced brake pads and discs onlyreach their optimum braking effect after severalhundred kilometers of driving. Compensate forthis by applying greater force to the brake pedal.

The first 1000 miles (1500 km)The more you look after the engine when it isnew, the more satisfied you will be with its per-formance in the future.RYou should therefore drive at varying vehicleand engine speeds for the first 1000 miles(1500 km).RAvoid heavy loads, e.g. driving at full throttle,during this period.RChange gear in good time, before the tach-ometer needle isÔ of the way to the red areaof the tachometer.RDo not manually shift to a lower gear to brakethe vehicle.RTry to avoid depressing the accelerator pedalbeyond the point of resistance (kickdown).

Additional breaking-in notes for Mercedes-AMGvehicles:RDo not drive faster than 85 mph (140 km/h)for the first 1,000 miles (1,500 km).ROnly allow the engine to reach a maximumengine speed of 4,500 rpm briefly.RChange gear in good time.RIdeally, for the first 1,000 miles (1,500 km),drive in the Comfort drive program.

After 1000 miles (1500 km), you can increasethe engine speed gradually and accelerate thevehicle to full speed.You should also observe these notes on break-ing in if the engine or parts of the drive train onyour vehicle have been replaced.Always observe the maximum permissiblespeed.

Important safety notes

G WARNINGObjects in the driver's footwell can restrict thepedal travel or obstruct a depressed pedal.The operating and road safety of the vehicle isjeopardized. There is a risk of an accident.Make sure that all objects in the vehicle arestowed correctly, and that they cannot enterthe driver's footwell. Install the floormatssecurely and as specified in order to ensuresufficient clearance for the pedals. Do not useloose floormats and do not place floormats ontop of one another.

G WARNINGUnsuitable footwear can hinder correct usageof the pedals, e.g.:Rshoes with thick solesRshoes with high heelsRslippersThere is a risk of an accident.Wear suitable footwear to ensure correctusage of the pedals.

G WARNINGIf you switch off the ignition while driving,safety-relevant functions are only availablewith limitations, or not at all. This could affect,for example, the power steering and the brakeboosting effect. You will require considerablymore effort to steer and brake. There is a riskof an accident.Do not switch off the ignition while driving.

Driving tips

Changing gearThe automatic transmission shifts to the indi-vidual gears automatically when it is in trans-mission position D. This automatic gear shiftingbehavior is determined by:Rthe selected drive programRthe position of the accelerator pedalRthe road speed

Accelerator pedal positionYour style of driving influences how the auto-matic transmission shifts gear:Rlittle throttle: early upshiftsRmore throttle: late upshifts

KickdownUse kickdown for maximum acceleration.X Depress the accelerator pedal beyond thepressure point.The automatic transmission shifts to a lowergear depending on the engine speed.

X Ease off the accelerator pedal once thedesired speed is reached.The automatic transmission shifts back up.

Rocking the vehicle freeShifting the transmission repeatedly betweengears D and R may help to free the vehicle if ithas become stuck in slush or snow. The vehi-cle's engine management system limits thespeed to a maximum of 5 mph (9 km/h) whenshifting back and forth. To shift back and forthbetween transmission positions D and R, movethe DIRECT SELECT lever up and down past thepoint of resistance.

Towing a trailerX Drive in the middle of the engine speed rangeon uphill gradients.

X Depending on the uphill or downhill gradient,use the left-hand steering wheel paddleshifter (Y page 150) to select a lower gear,even if cruise control or Distance PilotDISTRONIC are activated.

Transfer caseThis section is only valid for vehicles with 4-wheel drive (4MATIC). Power is always trans-mitted to both axles.

! Performance tests may only be carried outon a 2-axle dynamometer. The brake systemor transfer case could otherwise be damaged.Contact a qualified specialist workshop for aperformance test.

! Because ESP® is an automatic system, theengine and ignition must be switched off(SmartKey in position 0 or 1 or Start/Stopbutton in position 0 or 1) when the electricparking brake is being tested on a brake dyna-mometer (maximum 10 seconds).Braking triggered automatically by ESP® mayseriously damage the brake system.

! Vehicles with 4MATIC must not be towedwith either the front or the rear axle raised, asdoing so will damage the transmission.

If DEF is notrefilled, you will subsequently be unable tostart the engine.X Add at least 1 gal (3.8 l) of DEF.X Switch on the ignition for at least 60 seconds.X Start the engine.

i Have the DEF tank refilled at a qualified spe-cialist workshop.

Use the special DEF refill bottle when addingDEF between maintenance intervals. You canobtain further information from an authorizedMercedes-Benz Center or, if necessary, contactRoadside Assistance (Y page 27).If the outside temperature is below12‡ (Ò11†)it may be difficult to top up. If DEF is frozen andthere is an active warning indicator, it may notbe possible to add DEF. Park the vehicle in awarmer place, e.g. in a garage, until DEF hasbecome fluid again. It will then be possible toadd DEF again. Alternatively, have the DEF tankrefilled at a qualified specialist workshop.Further information about BlueTEC exhaust gasaftertreatment and DEF is available at anyauthorized Mercedes-Benz Center.

Important safety notesDEF is a water-soluble fluid for the exhaust gasaftertreatment of diesel engines. It is:Rnot poisonousRcolorless and odorlessRnot flammableWhen you open the DEF container, smallamounts of ammonia vapor may be released.Ammonia vapors have a pungent odor and areparticularly irritating to the skin, to mucousmembranes and to the eyes. You may experi-ence a burning sensation in your eyes, nose andthroat. Coughing and watering of the eyes arepossible.Do not inhale ammonia vapors. Fill the DEF tankonly in well-ventilated areas.

DEF must not come into contact with your skin,eyes or clothing and must not be swallowed.Keep DEF away from children.If you or other persons come into contact withDEF, observe the following:RRinse DEF from your skin immediately withsoap and water.RIf DEF comes into contact with your eyes,immediately rinse them thoroughly with cleanwater. Seek medical assistance withoutdelay.RIf DEF has been swallowed, rinse your mouthout immediately. Drink plenty of water. Seekmedical assistance without delay.RChange out of clothing contaminated withDEF immediately.

! Only use DEF in accordance withISO 22241. Do not mix any additives withDEF, and do not dilute DEF with water. Thismay destroy the BlueTEC exhaust gas after-treatment system.

! The vehicle must be parked on level groundto fill the DEF tank. The DEF tank can only befilled as intended with the vehicle parked on alevel surface. This avoids false level readings.Filling the tank is not permitted if the vehicleis not parked on a level surface. There is adanger of overfilling, which could result indamage to components of the BlueTECexhaust gas aftertreatment.

! Rinse surfaces that have come into contactwith DEF immediately with water or removeDEF using a damp cloth and cold water. If theDEF has already crystallized, use a spongeand cold water to clean it. DEF residues crys-tallize after time and contaminate the affec-ted surfaces.

! DEF is not a fuel additive and must not beadded to the fuel tank. If DEF is added to thefuel tank, this can lead to engine damage.

For further information on DEF, see(Y page 381).

The three inner areas display the current drivingstyle and light up green as a result of a particu-larly economical driving style. Depending on thedriving situation, up to two areas may light upsimultaneously.At the beginning of the journey, the three outerareas are empty and fill up as a result of eco-nomical driving. A higher level indicates a moreeconomical driving style. If the three outer areasare completely filled at the same time, the driverhas adopted the most economical driving stylefor the selected settings and prevailing condi-tions. The ECO display border lights up.The ECOdisplay does not indicate the actual fuelconsumption. The additionally achieved rangedisplayed under Bonus fr.

In addition to driving style, the actual consump-tion is affected by other factors, such as:RloadRtire pressureRcold startRchoice of routeRelectrical consumers switched onThese factors are not included in the ECO dis-play.An economical driving style specially requiresdriving at moderate engine speeds.Achieving a higher value in the categories"Acceleration" and "Constant":Robserve the gearshift recommendations.Rdrive the vehicle in the Comfort drive pro-gram.

On long journeys at a constant speed, e.g. on thehighway, only the outer area for "constant" willchange.The ECO display summarizes the driving stylefrom the start of the journey to its completion.Therefore, there are more marked changes inthe outer areas at the start of a journey. On lon-ger journeys, there are fewer changes. For moremarked changes, perform a manual rest(Y page 233).For further information on the ECO display, see(Y page 232).

Braking

Important safety notes

G WARNINGIf you shift down on a slippery road surface inan attempt to increase the engine's brakingeffect, the drive wheels could lose their grip.There is an increased danger of skidding andaccidents.Do not shift down for additional engine brak-ing on a slippery road surface.

Downhill gradients! On long and steep gradients, you mustreduce the load on the brakes by shifting to alower gear in good time. This allows you totake advantage of the engine's braking effect.

164 Driving tipsDrivingandparking

Page 167: GLS - Mercedes-Benz USA...WelcometotheworldofMercedes-Benz WeurgeyoutoreadthisOperator'sManual carefullyandfamiliarizeyourselfwiththevehi-clebeforedriving.Foryourownsafetyanda

This helps you to avoid overheating thebrakes and wearing them out excessively.When you take advantage of engine braking, adrive wheel may not turn for some time, e.g.on a slippery road surface. This could causedamage to the drive train. This type of damageis not covered by the Mercedes-Benz war-ranty.

Do not depress the brake pedal continuouslywhile the vehicle is in motion, e.g. causing thebrakes to rub by constantly applying light pres-sure to the pedal. This results in excessive andpremature wear to the brake pads.Use the left-hand steering wheel paddle shifterto shift into a lower gear in good time on longand steep downhill gradients. This is especiallyimportant if the vehicle is laden.This also applies if you have activated cruisecontrol, the speed limiter or Distance PilotDISTRONIC.This will use the braking effect of the engine, sothat less braking will be required tomaintain thespeed. This relieves the load on the brake sys-tem and prevents the brakes from overheatingand wearing too quickly.

Heavy and light loads

G WARNINGIf you rest your foot on the brake pedal whiledriving, the braking system can overheat. Thisincreases the stopping distance and can evencause the braking system to fail. There is arisk of an accident.Never use the brake pedal as a footrest. Neverdepress the brake pedal and the acceleratorpedal at the same time.

! Depressing the brake pedal constantlyresults in excessive and premature wear tothe brake pads.

If the brakes have been subjected to a heavyload, do not stop the vehicle immediately. Driveon for a short while. This allows the airflow tocool the brakes more quickly.

Wet roadsIf you have driven for a long time in heavy rainwithout braking, there may be a delayed reac-tion from the brakes when braking for the first

time. This may also occur after the vehicle hasbeen washed or driven through deep water.You then have to depress the brake pedal morefirmly. Maintain a greater distance from thevehicle in front.After driving on a wet road or having the vehiclewashed, brake firmly while paying attention tothe traffic conditions. This will warm up thebrake discs, thereby drying them more quicklyand protecting them against corrosion.

Limited braking performance on salt-treated roadsIf you drive on salted roads, a layer of salt resi-due may form on the brake discs and brakepads. This can result in a significantly longerbraking distance.RBrake occasionally to remove any possiblesalt residue. Make sure that you do notendanger other road users when doing so.RCarefully depress the brake pedal and thebeginning and end of a journey.RMaintain a greater distance to the vehicleahead.

Servicing the brakes! The brake fluid level may be too low, if:Rif the red brake warning lamp lights up inthe instrument cluster andRyou hear a warning tone while the engine isrunning

Observe additional warning messages in themultifunction display.The brake fluid level may be too low due tobrake pad wear or leaking brake lines.Have the brake system checked immediately.Consult a qualified specialist workshop toarrange this.

! A function or performance test should onlybe carried out on a 2-axle dynamometer. Ifyou wish to operate the vehicle on such adynamometer, please consult a qualified spe-cialist workshop in advance. You could oth-erwise damage the drive train or the brakesystem.

! Because ESP® is an automatic system, theengine and ignition must be switched off(SmartKey in position 0 or 1 or Start/Stopbutton in position 0 or 1) when the electric

parking brake is being tested on a brake dyna-mometer (maximum 10 seconds).Braking triggered automatically by ESP® mayseriously damage the brake system.

All checks and maintenance work on the brakesystem must be carried out at a qualified spe-cialist workshop.Have brake pads installed and brake fluidreplaced at a qualified specialist workshop.If the brake system has only been subject tomoderate loads, you should test the functional-ity of your brakes at regular intervals. To do so,depress the brake pedal firmly when driving at ahigh speed. This improves the grip of the brakepads.You can find a description of Brake Assist (BAS)on (Y page 64) or of BAS PLUS on (Y page 69).Mercedes-Benz recommends that you only havebrake pads/linings installed on your vehiclewhich have been approved for Mercedes-Benzvehicles or which correspond to an equivalentquality standard. Brake pads/liningswhich havenot been approved for Mercedes-Benz vehiclesor which are not of an equivalent quality couldaffect your vehicle's operating safety.Mercedes-Benz recommends that you only usebrake fluid that has been specially approved foryour vehicle by Mercedes-Benz, or which corre-sponds to an equivalent quality standard. Brakefluid which has not been approved forMercedes-Benz vehicles or which is not of anequivalent quality could affect your vehicle'soperating safety.

High-performance brake system(Mercedes-AMG vehicles)The high-performance brake system is designedfor heavy loads. This may lead to noise whenbraking. This will depend on:RSpeedRBraking forceREnvironmental conditions, such as tempera-ture and humidity

The wear of individual components of the brakesystem, such as the brake pads/linings or brakediscs, depends on the individual driving styleand operating conditions.For this reason, it is impossible to state a mile-age thatwill be valid under all circumstances. Anaggressive driving style will lead to high wear.

You can obtain further information about thisfrom your authorized Mercedes-Benz Center.New and replaced brake pads and discs onlyreach their optimum braking effect after severalhundred kilometers of driving. Compensate forthis by applying greater force to the brake pedal.Keep this in mind, and adapt your driving andbraking accordingly during this break-in period.Excessive heavy braking results in correspond-ingly high brake wear. Observe the# brakewear warning lamp in the instrument cluster andnote any brake status messages in the multi-function display. Especially for high perform-ance driving, it is important tomaintain and havethe brake system checked regularly.

Driving on wet roads

HydroplaningIf water has accumulated to a certain depth onthe road surface, there is a danger of hydro-planing occurring, even if:Ryou drive at low speeds.Rthe tires have adequate tread depth.For this reason, in the event of heavy rain or inconditions in which hydroplaning may occur,you must drive in the following manner:Rlower your speed.Ravoid ruts.Ravoid sudden steering movements.Rbrake carefully.

Driving on flooded roads! Do not drive through flooded areas. Checkthe depth of any water before driving throughit. Drive slowly through standing water. Oth-erwise, watermay enter the vehicle interior orthe engine compartment. This can damagethe electronic components in the engine orthe automatic transmission. Water can alsobe drawn in by the engine's air suction nozzlesand this can cause engine damage.

i Vehicles with the AIRMATIC package:select the raised vehicle level before drivingthrough a body of water.

Off-road fording! Under no circumstances should you accel-erate before entering the water. The bowwave could cause water to enter and damagethe engine and other assemblies.

! Do not open any of the vehicle's doors whilefording. Otherwise, water could get into thevehicle interior and damage the vehicle'selectronics and interior equipment.REstablish how deep the water is and the char-acteristics of the body of water before ford-ing.RSelect the highest possible vehicle level.RShift to a lower gear using the left-hand steer-ing wheel paddle shifter.RAvoid high engine speeds.REnter and exit the water at a flat place and ata steady walking pace.RDrive slowly and at an even speed through thewater.REnsure that a bow wave does not form as youdrive.RDo not stop and do not switch off the engine.Water offers a high degree of resistance, andthe ground is slippery and in some casesunstable. Therefore, it is difficult and danger-ous to pull away in the water.RClean any mud from the tire tread after ford-ing.RApply the brakes to dry them after fording.Always observe the fording depth values(Y page 385).

Winter driving

G WARNINGIf you shift down on a slippery road surface inan attempt to increase the engine's brakingeffect, the drive wheels could lose their grip.There is an increased danger of skidding andaccidents.Do not shift down for additional engine brak-ing on a slippery road surface.

G DANGERIf the exhaust pipe is blocked or adequateventilation is not possible, poisonous gases

such as carbon monoxide (CO) may enter thevehicle. This is the case, e.g. if the vehiclebecomes trapped in snow. There is a risk offatal injury.If you leave the engine or the auxiliary heatingrunning, make sure the exhaust pipe and areaaround the vehicle are clear of snow. Toensure an adequate supply of fresh air, open awindow on the side of the vehicle that is notfacing into the wind.

Have your vehicle winter-proofed at a qualifiedspecialist workshop at the onset of winter.Drive particularly carefully on slippery road sur-faces. Avoid sudden acceleration, steering andbrakingmaneuvers. Do not use cruise control orDistance Pilot DISTRONIC.If the vehicle threatens to skid or cannot bestopped when moving at low speed:X Shift the transmission to position N.When driving in snow with or without snowchains, select driving program Slippery(Y page 145).

i Vehicles with a diesel engine:do notcover the radiator, e.g. with a protectivecover. The measuring function of the on-board diagnosis system may otherwise pro-vide inaccurate values. Some of these valuesare required by law andmust therefore alwaysbe accurate.

The outside temperature indicator is notdesigned to serve as an ice-warning device andis therefore unsuitable for that purpose.Changes in the outside temperature are dis-played after a short delay.Indicated temperatures just above the freezingpoint do not guarantee that the road surface isfree of ice. The roadmay still be icy, especially inwooded areas or on bridges. You should payspecial attention to road conditions when tem-peratures are around the freezing point.For more information on driving with snowchains, see (Y page 348).For more information on driving with summertires, see (Y page 348).Observe the notes in the "Changing a wheel"section (Y page 366).

Off-road driving

Important safety notes

G WARNINGIf you drive on a steep incline at an angle orturn when driving on an incline, the vehiclecould slip sideways, tip and rollover. There is arisk of an accident.Always drive on a steep incline in the line offall (straight up or down) and do not turn thevehicle.

G WARNINGFlammable material such as leaves, grass ortwigsmay ignite if they come into contactwithhot parts of the exhaust system. There is a riskof fire.When driving off road or on unpaved roads,check the vehicle's underside regularly. Inparticular, remove parts of plants or otherflammable materials which have becometrapped. In the case of damage, contact aqualified specialist workshop.

G WARNINGIf the vehicle level is high, the vehicle center ofgravity is raised. This could cause the vehicleto tip over more easily on uphill or downhillgradients. There is a risk of an accident.Select the lowest possible vehicle level.

! There is a risk of damage to the vehicle if:Rthe vehicle becomes stuck, e.g. on a highcurb or an unpaved roadRyou drive too fast over an obstacle, e.g. acurb, speed bumps or a pothole in the roadRa heavy object strikes the underbody orparts of the chassis

In situations like this, the body, the under-body, chassis parts, wheels or tires could bedamaged without the damage being visible.Components damaged in this way can unex-pectedly fail or, in the case of an accident, nolonger withstand the strain they are designedto.If the underbody paneling is damaged, com-bustible materials such as leaves, grass or

twigs can gather between the underbody andthe underbody paneling. If these materialscome in contact with hot parts of the exhaustsystem, they can catch fire.In such situations, have the vehicle checkedand repaired immediately at a qualified spe-cialist workshop. If on continuing your jour-ney you notice that driving safety is impaired,pull over and stop the vehicle immediately,paying attention to road and traffic condi-tions. In such cases, consult a qualified spe-cialist workshop.

When driving off-road, substances such as sand,mud and water or water mixed with oil may getinto the brakes. This could result in a reducedbraking effect or in total brake failure and also inincreased wear and tear. The braking charac-teristics change depending on the materialingressing the brakes. Clean the brakes afterdriving off-road. If you detect a reduced brakingeffect or grinding noises, have the brake systemchecked in a qualified specialist workshop assoon as possible. Adapt your driving style to thedifferent braking characteristics.Driving off-road increases the likelihood of dam-age to the vehicle, which, in turn, can lead tofailure of the mechanical assembly or systems.Adapt your driving style to suit the terrain con-ditions. Drive carefully. Have damage to thevehicle rectified immediately at a qualified spe-cialist workshop.Do not switch to transmission position N whendriving off-road. If you try to brake the vehicleusing the service brake, you could lose controlof the vehicle. If the gradient is too steep for yourvehicle, drive back down in reverse gear.

Driving systems

Intelligent DriveMercedes-Benz Intelligent Drive stands for inno-vative driver assistance and safety systemswhich enhance comfort and support the driver incritical situations. With these intelligent co-ordi-nated systems Mercedes-Benz has set a mile-stone on the path towards autonomous driving.Mercedes-Benz Intelligent Drive embraces allelements of active and passive safety in onewellthought out system – for the safety of the vehi-cle occupants and that of other road users.Further information on driving safety systems(Y page 63).

Cruise control

General notesCruise control maintains a constant road speedfor you. It brakes automatically in order to avoidexceeding the set speed. You must select alower gear in good time on long and steep down-hill gradients, especially if the vehicle is laden ortowing a trailer. By doing so, youwill make use ofthe braking effect of the engine. This relieves the

load on the brake system and prevents thebrakes from overheating and wearing tooquickly.Use cruise control only if road and traffic con-ditions make it appropriate to maintain a steadyspeed for a prolonged period. You can store anyroad speed above 20 mph (30 km/h).

i Cruise control should not be activated whendriving off-road.

Important safety notesIf you fail to adapt your driving style, cruise con-trol can neither reduce the risk of an accidentnor override the laws of physics. Cruise controlcannot take into account the road, traffic andweather conditions. Cruise control is only anaid. You are responsible for the distance to thevehicle in front, for vehicle speed, for braking ingood time and for staying in your lane.Do not use cruise control:Rin road and traffic conditions which do notallow you tomaintain a constant speed, e.g. inheavy traffic or on winding roadsRon slippery road surfaces. Braking or accel-erating could cause the drive wheels to losetraction and the vehicle could then skidRwhen there is poor visibility, e.g. due to fog,heavy rain or snow

If there is a change of drivers, advise the newdriver of the speed stored.

Distance Pilot DISTRONIC

General notesDistance Pilot DISTRONIC regulates the speedand automatically helps you maintain the dis-tance to the vehicle detected in front. Vehiclesare detected with the aid of the radar sensorsystem. Distance Pilot DISTRONIC brakes auto-matically so that the set speed is not exceeded.You must select a lower gear in good time onlong and steep downhill gradients, especially ifthe vehicle is laden or towing a trailer. By doingso, you will make use of the braking effect of theengine. This relieves the load on the brake sys-tem and prevents the brakes from overheatingand wearing too quickly.If Distance Pilot DISTRONIC detects that there isa risk of a collision, you will be warned visuallyand acoustically. Without your intervention, Dis-tance Pilot DISTRONIC cannot prevent a colli-sion. An intermittent warning tone will thensound and the distance warning lamp will lightup in the instrument cluster. Brake immediatelyin order to increase the distance to the vehicle infront or take evasive action provided it is safe todo so.For Distance Pilot DISTRONIC to assist youwhen driving, the radar sensor system must beoperational.Distance Pilot DISTRONIC operates in the rangebetween 0 mph (0 km/h) and 120 mph(200 km/h).Do not use Distance Pilot DISTRONIC while driv-ing on roads with steep gradients.Since Distance Pilot DISTRONIC transmits radarwaves, it can resemble the radar detectors ofthe responsible authorities. You can refer to therelevant chapter in the Operator's Manual ifquestions are asked about this.

You areresponsible for the distance to the vehicle infront, for vehicle speed, for braking in good timeand for staying in your lane.Do not use Distance Pilot DISTRONIC:Rin road and traffic conditions which do notallow you tomaintain a constant speed, e.g. inheavy traffic or on winding roadsRon slippery road surfaces. Braking or accel-erating could cause the drive wheels to losetraction and the vehicle could then skidRwhen there is poor visibility, e.g. due to fog,heavy rain or snow

Distance Pilot DISTRONIC may not detect nar-row vehicles driving in front, e.g.motorcycles, orvehicles driving on a different line.In particular, the detection of obstacles can beimpaired if:Rthere is dirt on the sensors or anything elsecovering the sensorsRthere is snow or heavy rainRthere is interference by other radar sourcesRthere are strong radar reflections, for exam-ple, in parking garages

If Distance Pilot DISTRONIC no longer detects avehicle in front, it may unexpectedly accelerateto the speed stored.This speed may:Rbe too high if you are driving in a filter lane oran exit laneRbe so high when driving in the right-hand lanethat you overtake vehicles in the left-handlaneRbe so high when driving in the left-hand lanethat you overtake vehicles in the right-handlane

If there is a change of drivers, advise the newdriver of the speed stored.

Activating Distance Pilot DISTRONIC

Activation conditionsTo activate Distance Pilot DISTRONIC, the fol-lowing conditions must be fulfilled:Rthe engine must be started. It may take up totwo minutes of driving before Distance PilotDISTRONIC is ready for use.Rthe electric parking brake must be released.RESP® must be active, but not intervening.Rthe transmission must be in position D.Rthe driver's door must be closed when youshift from P to D or your seat belt must befastened.Rthe front-passenger door and rear doorsmustbe closed.Rthe Offroad Plus drive programmust be deac-tivated (vehicles with the Off-Road Engineer-ing package).RDSR must be deactivated.Rthe vehicle must not skid.

ActivatingX Briefly pull the cruise control lever towardsyou=, up: or down?.Distance Pilot DISTRONIC is activated.

X Remove your foot from the accelerator pedal.Your vehicle adapts its speed to that of thevehicle in front, but only up to the desiredstored speed.

i If you do not fully release the acceleratorpedal, the Distance Pilot Passive mes-sage appears in themultifunction display. Theset distance to a slower-moving vehicle infront will then not be maintained. You will bedriving at the speed you determine by theposition of the accelerator pedal.

You can also activate Distance Pilot DISTRONICwhen stationary. The lowest speed that can beset is 20 mph (30 km/h).X Briefly pull the cruise control lever towardsyou=, up: or down?.Distance Pilot DISTRONIC is activated.

Activates at the current speed/laststored speedG WARNINGIf you call up the stored speed and it differsfrom the current speed, the vehicle acceler-

ates or decelerates. If you do not know thestored speed, the vehicle could accelerate orbrake unexpectedly. There is a risk of an acci-dent.Pay attention to the road and traffic condi-tions before calling up the stored speed. If youdo not know the stored speed, store thedesired speed again.

X Briefly pull the cruise control lever towardsyou=.

X Remove your foot from the accelerator pedal.The first time Distance Pilot DISTRONIC isactivated, it stores the current speed or reg-ulates the speed of the vehicle to the storedspeed.

Driving with Distance Pilot DISTRONIC

Pulling away and drivingX If you want to pull away with DistancePilot DISTRONIC: remove your foot from thebrake pedal.

X Briefly pull the cruise control lever towardsyou?.

orX Accelerate briefly.Your vehicle pulls away and adapts its speedto that of the vehicle in front. If no vehicle isdetected in front, your vehicle accelerates tothe set speed.

The vehicle can also pull away when it is facingan unidentified obstacle or is driving on a differ-ent line from another vehicle. The vehicle thenbrakes automatically.If there is no vehicle in front, Distance PilotDISTRONIC operates in the same way as cruisecontrol.If Distance Pilot DISTRONIC detects a slower-moving vehicle in front, it brakes your vehicle. Inthis way, the distance you have selected ismain-tained.If Distance Pilot DISTRONIC detects a faster-moving vehicle in front, it increases the drivingspeed. However, the vehicle is only acceleratedup to the speed you have stored.

Selecting the drive programDistance Pilot DISTRONIC supports a sportydriving style if you have selected the Sport orSport Plus drive program (Y page 149). Accel-eration behind the vehicle in front or to the setspeed is then noticeably more dynamic. If youhave selected the Comfort drive program, thevehicle accelerates more gently. This setting isrecommended in stop-and-start traffic.

Changing lanesIf you change to the overtaking lane, DistancePilot DISTRONIC supports you if:Ryou are driving faster than 45 mph (70 km/h)Ryou switch on the appropriate turn signalRDistance Pilot DISTRONIC does not currentlydetect a danger of collision

If these conditions are fulfilled, your vehicle isaccelerated. Acceleration will be interrupted ifchanging lanes takes too long or if the distancebetween your vehicle and the vehicle in frontbecomes too small.

i When you change lanes, Distance PilotDISTRONIC monitors the right lane (in left-side traffic) or the left lane (in right-side traf-fic).

StoppingG WARNINGWhen leaving the vehicle, even if it is brakedonly by DISTRONIC PLUS, it could roll away if:Rthere is a malfunction in the system or inthe voltage supply.RDISTRONIC PLUS has been deactivatedwith the cruise control lever, e.g. by a vehi-cle occupant or from outside the vehicle.Rthe electrical system in the engine com-partment, the battery or the fuses havebeen tampered with.Rthe battery is disconnected.Rthe accelerator pedal has been depressed,e.g. by a vehicle occupant.

There is a risk of an accident.If you wish to exit the vehicle, always turn offDISTRONIC PLUS and secure the vehicleagainst rolling away.

If Distance Pilot DISTRONIC detects that thevehicle in front is stopping, it brakes your vehicleto a stop.Once your vehicle is stationary, it remains sta-tionary and you do not need to depress thebrake.After a time, the electric parking brake securesthe vehicle and relieves the service brake.Depending on the specified minimum distance,your vehicle will come to a standstill at a suffi-cient distance behind the vehicle in front. Thespecified minimum distance is set using thecontrol on the cruise control lever.The transmission is shifted automatically toposition P if, with Distance Pilot DISTRONICactivated and the vehicle stationary:Rthe driver's door is open and the driver's seatbelt is unfastened.Rthe engine is switched off, unless it is auto-matically switched off by the ECO start/stopfunction.

Tips for driving with Distance PilotDISTRONIC

General notesPay particular attention in the following trafficsituations:RCornering, entering and exiting a bend: theability of Distance Pilot DISTRONIC to detectvehicles during cornering is limited. Your vehi-cle may brake unexpectedly or late.RDriving on a different line: Distance PilotDISTRONICmay not detect vehicleswhich arenot driving in the middle of their lane. The dis-tance to the vehicle in front will be too short.ROther vehicles changing lanes: Distance PilotDISTRONIC has not detected the vehicle cut-ting in yet. The distance to this vehicle will betoo short.RNarrow vehicles: Distance Pilot DISTRONIChas not yet detected the vehicle in front onthe edge of the road because of its narrowwidth. The distance to the vehicle in front willbe too short.RObstacles and stationary vehicles: DistancePilot DISTRONIC does not brake for obstaclesor stationary vehicles. If, for example, thedetected vehicle turns a corner and an obsta-cle or stationary vehicle is then revealed, Dis-tance Pilot DISTRONIC will not brake forthem.RCrossing traffic: Distance Pilot DISTRONICmay mistakenly detect vehicles that arecrossing your lane. Activating Distance PilotDISTRONIC at, for example, a traffic light withcrossing traffic, could cause your vehicle topull away at the wrong time.

In such situations, brake if necessary. DistancePilot DISTRONIC will then be deactivated.

Distance Pilot DISTRONIC with SteeringPilot

General notes

Distance Pilot DISTRONIC with Steering Pilotaids you in keeping the vehicle in the center ofthe driving lane by means of moderate steeringinterventions in a speed range from 0 - 125mph(0 - 200 km/h).It monitors the area in front of your vehicle bymeans of camera system: at the top of thewindshield.In a speed range from 0 - 37 mph (0 - 60 km/h),the advanced automatic pulling away functionfocuses on the vehicle in front, taking intoaccount lanemarkings, e.g. when following vehi-cles in a traffic jam.At speeds of more than 37 mph (60 km/h),Steering Pilot focuses on clear lane markings(left and right), only focusing on the vehicle infront if clear lane markings are not present.If these conditions are not present, SteeringPilot cannot provide assistance.Distance Pilot DISTRONIC must be active inorder for the function to be available.

Important safety notesIf you fail to adapt your driving style, DistancePilot DISTRONIC and Steering Pilot can neitherreduce the risk of an accident nor override thelaws of physics. It cannot take into accountroad, weather or traffic conditions. DistancePilot DISTRONIC with Steering Pilot is only anaid. You are responsible for the distance to thevehicle in front, for vehicle speed, for braking ingood time and for staying in your lane.Distance Pilot DISTRONIC with Steering Pilotdoes not detect road and traffic conditions anddoes not detect all road users. If you are follow-ing a vehiclewhich is driving towards the edge ofthe road, your vehicle could come into contact

with the curb or other road boundaries. Be par-ticularly aware of other road users, e.g. cyclists,that are directly next to your vehicle.Obstacles such as traffic pylons on the lane orprojecting out into the lane are not detected.An inappropriate steering intervention, e.g. afterintentionally driving over a lane marking, can becorrected at any time if you steer slightly in theopposite direction.DISTRONIC PLUS with Steering Pilot cannotcontinuously keep your vehicle in lane. In somecases, the steering intervention is not sufficientto bring the vehicle back to the lane. In suchcases, you must steer the vehicle yourself toensure that it does not leave the lane.The support provided by the system can beimpaired if:Rthere is poor visibility, e.g. due to insufficientillumination of the road, or due to snow, rain,fog or sprayRthere is glare, e.g. from oncoming traffic, thesun or reflections (e.g. when the road surfaceis wet)Rthewindshield is dirty, fogged up, damaged orcovered, for instance by a sticker, in the vicin-ity of the cameraRthere are no, several or unclear lanemarkingsfor a lane, e.g. in areas with road constructionworkRthe lanemarkings are worn away, dark or cov-ered up, e.g. by dirt or snowRthe distance to the vehicle in front is too smalland the lane markings thus cannot be detec-tedRthe lane markings change quickly, e.g. lanesbranch off, cross one another or mergeRthe road is narrow and windingRthere are strong shadows cast on the roadThe system is switched to passive and no longerassists you by performing steering interventionsif:Ryou actively change laneRyou switch on the turn signalRtake your hands off the steering wheel or donot steer for a prolonged period of time

Level control (vehicles with the Off-road Engineering package)

Important safety notesLevel control adapts the vehicle level automati-cally to the current operating and driving situa-tion. This results in reduced fuel consumptionand improved handling.Make changes to the vehicle level while thevehicle is in motion. This enables the vehicle toadjust to the new level as quickly as possible.The vehicle level may change visibly if you parkthe vehicle and the outside temperaturechanges. If the temperature drops, the vehiclelevel is lower; with an increase in temperature,the vehicle level rises.If you unlock the vehicle or open a door, thevehicle begins to compensate for load discrep-ancies while still parked. However, for signifi-cant level changes, such as after the vehicle hasbeen stationary for a long period, the enginemust be on. For safety reasons, the vehicle isonly lowered when the doors are closed. Low-ering is interrupted if a door is opened, and itcontinues once the door has been closed.Further information about "Driving off-road"(Y page 168).

G WARNINGWhen the vehicle is being lowered, peoplecould become trapped if their limbs arebetween the vehicle body and the wheels orunderneath the vehicle. There is a risk ofinjury.Make sure no one is underneath the vehicle orin the immediate vicinity of the wheel archeswhen the vehicle is being lowered.

G WARNINGWhen you drive with the vehicle raised, thedriving characteristics could be impaired bythe vehicle's raised center of gravity. The vehi-cle could rollover more easily, for example ona bend. There is a risk of an accident.

Always select as low a vehicle level as possi-ble and adjust your driving style.

G WARNINGWhen you drive with the chassis lowered orraised, the vehicle's braking and driving char-acteristics can be significantly impaired. Youcould also exceed the permissible vehicleheight if the chassis is raised. There is a risk ofan accident.Adjust the vehicle level before pulling away.

G WARNINGDue to the high center of gravity, the vehiclemay start to skid and roll over in the event ofan abrupt steering maneuver and/or whenthe vehicle's speed is not adapted to the roadconditions. There is a risk of an accident.Always adapt your speed and driving style tothe vehicle's driving characteristics and to theprevailing road and weather conditions.

! When driving on extremely rough terrain,select a high vehicle level in good time. Makesure there is always sufficient ground clear-ance. You will otherwise damage the vehicle.RUtility vehicles have a significantly higher roll-over rate than other types of vehicles.Failure to operate this vehicle safely mayresult in an accident, rollover of the vehicle,and severe or fatal injury.RIn a rollover crash, an unbelted person is sig-nificantly more likely to die than a personwearing a seat belt.You and all vehicle occupants should alwayswear your seat belts.

Basic settingsThe extent to which the vehicle is raised or low-ered depends on the basic setting selected.Select:Rthe Comfort or Sport drive program for driv-ing on normal roadsRthe Offroad drive program for driving on eas-ily negotiable off-road terrainRthe Offroad Plus drive program for off-roaddriving

Vehicle level

Important safety notesG WARNINGWhen the vehicle is being lowered, peoplecould become trapped if their limbs arebetween the vehicle body and the wheels orunderneath the vehicle. There is a risk ofinjury.Make sure no one is underneath the vehicle orin the immediate vicinity of the wheel archeswhen the vehicle is being lowered.

G WARNINGWhen you drive with the vehicle raised, thedriving characteristics could be impaired bythe vehicle's raised center of gravity. The vehi-cle could rollover more easily, for example ona bend. There is a risk of an accident.Always select as low a vehicle level as possi-ble and adjust your driving style.

G WARNINGWhen you drive with the chassis lowered orraised, the vehicle's braking and driving char-acteristics can be significantly impaired. Youcould also exceed the permissible vehicleheight if the chassis is raised. There is a risk ofan accident.Adjust the vehicle level before pulling away.

G WARNINGDue to the high center of gravity, the vehiclemay start to skid and roll over in the event ofan abrupt steering maneuver and/or whenthe vehicle's speed is not adapted to the roadconditions. There is a risk of an accident.

Always adapt your speed and driving style tothe vehicle's driving characteristics and to theprevailing road and weather conditions.

! When driving on extremely rough terrain,select a high vehicle level in good time. Makesure there is always sufficient ground clear-ance. You will otherwise damage the vehicle.RUtility vehicles have a significantly higher roll-over rate than other types of vehicles.Failure to operate this vehicle safely mayresult in an accident, rollover of the vehicle,and severe or fatal injury.RIn a rollover crash, an unbelted person is sig-nificantly more likely to die than a personwearing a seat belt.You and all vehicle occupants should alwayswear your seat belts.

General notesOnly select raised level if this is appropriate forthe road conditions. Otherwise, fuel consump-tionmay increase and handlingmay be affected.Make changes to the vehicle level while thevehicle is in motion. This enables the vehicle toadjust to the new level as quickly as possible.The vehicle level may change visibly if you parkthe vehicle and the outside temperaturechanges. If the temperature drops, the vehiclelevel is lower; with an increase in temperature,the vehicle level rises.If you unlock the vehicle or open a door, thevehicle begins to compensate for load discrep-ancies while still parked. However, for signifi-cant level changes, such as after the vehicle hasbeen stationary for a long period, the enginemust be on. For safety reasons, the vehicle isonly lowered when the doors are closed. Low-ering is interrupted if a door is opened, and itcontinues once the door has been closed.Vehicles with no trailer coupled: below aspeed of 37 mph (60 km/h), you can choosebetween the normal and raised vehicle level.Select the normal vehicle level for normal roadsurfaces and the raised vehicle level for drivingwith snow chains or on particularly poor roadsurfaces.

Parking Assist PARKTRONIC

Important safety notesParking Assist PARKTRONIC is an electronicparking aid with ultrasound. It monitors the areaaround your vehicle using six sensors in thefront bumper and six sensors in the rearbumper. Parking Assist PARKTRONIC visuallyand audibly indicates the distance between yourvehicle and an object.Parking Assist PARKTRONIC is only an aid. It isnot a replacement for your attention to yourimmediate surroundings. You are alwaysresponsible for safe maneuvering, parking andexiting a parking space. When maneuvering,parking or pulling out of a parking space, makesure that there are no persons, animals orobjects in the area in which you are maneuver-ing.

! When parking, pay particular attention toobjects above or below the sensors, such asflower pots or trailer drawbars. PARKTRONICdoes not detect such objects when they are inthe immediate vicinity of the vehicle. Youcould damage the vehicle or the objects.The sensors may not detect snow and otherobjects that absorb ultrasonic waves.Ultrasonic sources such as an automatic carwash, the compressed-air brakes on a truckor a pneumatic drill could cause PARKTRONICto malfunction.PARKTRONIC may not function correctly onuneven terrain.

! Fold in the ball coupling if the trailer towhitch is not required. PARKTRONIC measuresthe minimum detection range to an obstaclefrom the bumper, not the ball coupling.

Parking Assist PARKTRONIC is deactivated forthe rear area when you establish an electricalconnection between your vehicle and a trailer.Parking Assist PARKTRONIC is activated auto-matically when you:Rswitch on the ignitionRshift the transmission to position D, R or NRrelease the electric parking brakeParking Assist PARKTRONIC is deactivated atspeeds above 11 mph (18 km/h).

Parking Pilot

General notesParking Pilot is an electronic parking aid withultrasound. It measures the road on both sidesof the vehicle. A parking symbol indicates a suit-able parking space. Active steering interventionand brake application can assist you duringparking. Parking Assist PARKTRONIC is alsoavailable (Y page 190).

Important safety notesParking Pilot is only an aid. It is not a replace-ment for your attention to your immediate sur-roundings. You are always responsible for safemaneuvering, parking and exiting a parkingspace. Make sure that no persons, animals orobjects are in the maneuvering range.When Parking Assist PARKTRONIC is deactiva-ted, Parking Pilot is also unavailable.

G WARNINGWhile parking or pulling out of a parkingspace, the vehicle swings out and can driveonto areas of the oncoming lane. This couldresult in a collision with another road user.There is a risk of an accident.Pay attention to other road users. Stop thevehicle if necessary or cancel the Active Park-ing Assist parking procedure.

! If unavoidable, you should drive over obsta-cles such as curbs slowly and not at a sharpangle. Otherwise, you may damage thewheels or tires.

Parking Pilot may show parking spaces whichare not suitable for parking, e.g.:Rwhere parking or stopping is prohibitedRin front of driveways or entrances and exitsRon unsuitable surfaces

Parking tips:ROn narrow roads, drive as close to the parkingspace as possible.RParking spaces that are littered or overgrownmight be identified or measured incorrectly.RParking spaces that are partially occupied bytrailer drawbars might not be identified assuch or be measured incorrectly.RSnowfall or heavy rain may lead to a parkingspace being measured inaccurately.RPay attention to the warning messages ofParking Pilot PARKTRONIC during the parkingprocedure (Y page 190)RYou can intervene in the steering procedureto correct it at any time. Parking Pilot will thenbe canceled.RWhen transporting a load that protrudes fromyour vehicle, you must not use Parking PilotRNever use Parking Pilot when snow chains areinstalled.RMake sure that the tire pressures are alwayscorrect. This has a direct influence on theparking characteristics of the vehicle.

Use Parking Pilot for parking spaces that are:Rparallel or at right angles to the direction oftravelRthat are on straight roads, not bendsRthat are on the same level as the road, e.g. noton the pavement

Detecting parking spacesObjects located above the detection range ofParking Pilot will not be detected when the park-ing space is measured. These are not taken intoaccount when the parking procedure is calcula-ted, e.g. overhanging loads, tail sections or load-ing ramps of trucks. Parking Pilot may thereforeguide you into the parking space too early.

G WARNINGIf there are objects above the detection range:RActive Park Assist may steer too earlyRthe vehicle may not stop in front of theseobjects

You may cause a collision as a result. There isa risk of an accident.

If objects are located above the detectionrange, stop and deactivate Active ParkingAssist.

ATTENTION ASSIST

General notesATTENTION ASSIST helps you during long,monotonous journeys, such as on highways. It isactive in the 37 mph (60 km/h) to 125 mph(200 km/h) range. If ATTENTION ASSISTdetects typical indicators of fatigue or increas-ing lapses in concentration on the part of thedriver, it suggests taking a break.

Important safety notesATTENTION ASSIST is only an aid to the driver. Itmight not always recognize fatigue or increasinginattentiveness in time or fail to recognize themat all. The system is not a substitute for a well-rested and attentive driver.The functionality of ATTENTION ASSIST isrestricted and warnings may be delayed or notoccur at all:Rif the length of the journey is less than approx-imately 30 minutesRif the road condition is poor, e.g. if the surfaceis uneven or if there are potholesRif there is a strong side windRif you have adopted a sporty driving style withhigh cornering speeds or high rates of accel-erationRif you are predominantly driving slower than37 mph (60 km/h) or faster than 125 mph(200 km/h)Rif you are driving with the Steering Pilot ofDistance Pilot DISTRONIC activatedRif the time has been set incorrectlyRin active driving situations, such as when youchange lanes or change your speed

The attention level evaluation is deleted andrestarts when the journey is continued, if:Ryou switch off the engineRyou take off your seat belt and open the driv-er's door, e.g. for a change of drivers or totake a break

Displaying the attention level

You can have current status information dis-played in the assistance menu (Y page 236) ofthe on-board computer.X Select the Assistance display for ATTENTIONASSIST using the on-board computer(Y page 237).

The following information is displayed:RLength of the journey since the last break.Rthe attention level determined by ATTENTIONASSIST, displayed in a bar display in five levelsfrom high to low.RIf ATTENTION ASSIST is unable to calculatethe attention level and cannot output a warn-ing, the System suspended messageappears. The bar display then changes thedisplay, e.g. if you are driving at a speed below37 mph (60 km/h) or above 125 mph(200 km/h).

Activating ATTENTION ASSISTX Activate ATTENTION ASSIST using the on-board computer (Y page 237).The system determines the attention level ofthe driver depending on the setting selected:

Standard selected: the sensitivity with whichthe system determines the attention level is setto normal.Sensitive selected: the sensitivity is set higher.The attention level detected by Attention Assist

is adapted accordingly and the driver is warnedearlier.When ATTENTION ASSIST is deactivated, theÀ symbol and OFF appear in the multifunc-tion display in the assistance display when theengine is running.WhenATTENTIONASSIST has been deactivated,it is automatically reactivated after the enginehas been stopped. The sensitivity selected cor-responds to the last selection activated (stand-ard/sensitive).

Warning in the multifunction displayIf fatigue or increasing lapses in concentrationare detected, a warning appears in the multi-function display: Attention Assist: Take aBreak!In addition to the message shown in the multi-function display, you will then hear a warningtone.X If necessary, take a break.X Confirm the message by pressing theabutton on the steering wheel.

On long journeys, take regular breaks in goodtime to allow yourself to rest. If you do not takea break, you will be warned again after15 minutes at the earliest. This will only happenif ATTENTION ASSIST still detects typical indi-cators of fatigue or increasing lapses in concen-tration.Vehicles with COMAND: if a warning is issuedin the multifunction display, a service stationsearch is performed in COMAND. You can selecta service station and navigation to this servicestation will then begin. This function can be acti-vated and deactivated in COMAND.

Traffic Sign Assist

General notesTraffic Sign Assist displays the maximum speedpermitted to the driver in the instrument cluster.The data stored in the navigation system andgeneral traffic regulations are used to determinethe current speed limit.As Traffic Sign Assist is a map-based system,traffic signs put up temporarily (e.g. near road-works) are not detected.

If a traffic sign that is relevant to your vehicle ispassed, the display of the speed limits is upda-ted.Traffic signs with a restriction indicated by anadditional sign (e.g. in wet conditions) are alsoshown.The traffic signs are only displayed with therestrictions if:Rthe regulation must be observed with therestriction, orRTraffic Sign Assist is unable to determinewhether the restriction applies

If Traffic Sign Assist is unable to determine amaximumpermitted speed fromany of the avail-able sources, no speed limit is displayed in theinstrument cluster either.

Traffic Sign Assist is not available in all coun-tries. In this case, symbol: is shown in theassistance graphic display (Y page 237).

Important safety notesTraffic SignAssist is only an aid and is not alwaysable to correctly display speed limits. Trafficsigns always have priority over the Traffic SignAssist display.The system may be either functionally impairedor temporarily unavailable if the information inthe digital streetmap of the navigation system isincorrect or out of date.

Lane Tracking package

General notesThe Lane Tracking package consists of BlindSpot Assist (Y page 207) and Lane KeepingAssist (Y page 209).

Blind Spot Assist

General notesBlind Spot Assist monitors the areas on eitherside of the vehicle that are not visible to thedriver with two lateral, rear-facing radar sen-sors. A warning display in the exterior mirrorsdraws your attention to vehicles detected in themonitored area. If you then switch on the cor-responding turn signal to change lane, you willalso receive an optical and audible warning.Blind Spot Assist supports you from a speed ofapproximately 20 mph (30 km/h).

Important safety notesG WARNINGBlind Spot Assist does not react to:Rvehicles overtaken too closely on the side,placing them in the blind spot areaRvehicles which approach with a large speeddifferential and overtake your vehicle

As a result, Blind Spot Assist may not givewarnings in such situations. There is a risk ofan accident.Always observe the traffic conditions care-fully, and maintain a safe lateral distance.

Blind Spot Assist is only an aid. It may fail todetect some vehicles and is no substitute forattentive driving. Always ensure that there issufficient distance to the side for other roadusers and obstacles.

Vehicles in the monitoring range are then notindicated.

Blind Spot Assist monitors the area up to 10 ft(3 m) behind your vehicle and directly next toyour vehicle, as shown in the diagram.If the lanes are narrow, vehicles driving in thelane beyond the lane next to your vehiclemay beindicated, especially if the vehicles are not driv-ing in the middle of their lane. This may be thecase if there are vehicles driving at the inneredge of their lanes.On very wide lanes, vehicles in the adjacent lanemay not be shown if they are too far away.Due to the nature of the system:Rwarnings may be issued in error when drivingclose to crash barriers or similar solid laneborders.Rthe warning is canceled when driving for anextended period next to long vehicles, such astrucks.

Warning displayBlind Spot Assist is not active at speeds belowapproximately 20 mph (30 km/h). Vehicles inthe monitoring range are then not indicated.

: Yellow indicator lamp/red warning lampWhen Blind Spot Assist is activated, indicatorlamp: in the exterior mirrors lights up yellowat speeds of up to 20mph (30 km/h). At speedsabove 20 mph (30 km/h), the indicator lampgoes out and Blind Spot Assist is operational.If a vehicle is detected within the blind spotmonitoring range at speeds above 20 mph(30 km/h), warning lamp: on the correspond-ing side lights up red. This warning is alwaysemitted when a vehicle enters the blind spotmonitoring range from behind or from the side.When you overtake a vehicle, the warning onlyoccurs if the difference in speed is less than7 mph (12 km/h).The yellow indicator lamp goes out if reversegear is engaged. In this event, Blind Spot Assistis no longer active.The brightness of the indicator/warning lampsis adjusted automatically according to the ambi-ent light.

Collision warningIf a vehicle is detected in themonitoring range ofBlind Spot Assist and you switch on the corre-sponding turn signal, a double warning tonesounds. Red warning lamp: flashes.

Lane Keeping Assist

General notes

: Lane Keeping Assist cameraLaneKeepingAssistmonitors the area in front ofyour vehicle with camera:, which is mountedat the top of thewindshield. Active LaneKeepingAssist detects lane markings on the road andcan warn you before you leave your lane unin-tentionally.This function is available in the range between40mph and 120mph (60 km/h and 200 km/h).A warning may be given if a front wheel passesover a lanemarking. It will warn you bymeans ofintermittent vibration in the steering wheel forup to 1.5 seconds.

Important safety notesG WARNINGLane Keeping Assist may not always clearlyrecognize lane markings.

In this case, Lane Keeping Assist may:Rgive an unnecessary warningRnot give a warningThere is a risk of an accident.Always pay particular attention to the trafficsituation and stay in lane, in particular ifwarned by Lane Keeping Assist.

G WARNINGThe Lane Keeping Assist warning does notreturn the vehicle to the original lane. There isa risk of an accident.You should always steer, brake or accelerateyourself, in particular if warned by Lane Keep-ing Assist.

If you fail to adapt your driving style, Lane Keep-ing Assist can neither reduce the risk of an acci-dent nor override the laws of physics. LaneKeeping Assist cannot take into account theroad, traffic and weather conditions. Lane Keep-ing Assist is merely an aid. You are responsiblefor the distance to the vehicle in front, for vehi-cle speed, for braking in good time and for stay-ing in your lane.The Lane Keeping Assist does not keep the vehi-cle in the lane.The systemmay be impaired ormay not functionif:Rthere is poor visibility, e.g. due to insufficientillumination of the road, or due to snow, rain,fog or sprayRthere is glare, e.g. from oncoming traffic, thesun or reflection from other vehicles (e.g. ifthe road surface is wet)Rthewindshield is dirty, fogged up, damaged orcovered, for instance by a sticker, in the vicin-ity of the cameraRthere are no, several or unclear lanemarkingsfor a lane, e.g. in areas with road constructionworkRthe lanemarkings are worn away, dark or cov-ered up, e.g. by dirt or snowRthe distance to the vehicle in front is too smalland the lane markings thus cannot be detec-tedRthe lane markings change quickly, e.g. lanesbranch off, cross one another or merge

Driving Assistance PLUS package

General notesThe Driving Assistance Plus package consists ofDistance Pilot DISTRONIC (Y page 174), ActiveBlind Spot Assist (Y page 210) and Active LaneKeeping Assist (Y page 213).

Active Blind Spot Assist

General notesActive Blind Spot Assist monitors the areas oneither side of the vehicle that are not directlyvisible to the driver with two lateral, rear-facingradar sensors. A warning lamp lights up in theexterior mirrors and draws your attention tovehicles detected in the monitored area. If youthen switch on the corresponding turn signal tochange lanes, you will also receive a visual andaudible collision warning. If a risk of lateral col-lision is detected, corrective braking may helpyou avoid a collision. Before a course-correctingbrake application, Active Blind Spot Assist eval-uates the space in the direction of travel and atthe sides of the vehicle. For this, Active BlindSpot Assist uses the forward-facing radar sen-sors.Active Blind Spot Assist supports you from aspeed of approximately 20 mph (30 km/h).

Important safety notesActive Blind Spot Assist is only an aid and is nota substitute for attentive driving.

G WARNINGActive Blind Spot Assist does not react to:Rvehicles overtaken too closely on the side,placing them in the blind spot areaRvehicles which approach with a large speeddifferential and overtake your vehicle

As a result, Active Blind Spot Assist may nei-ther give warnings nor intervene in such sit-uations. There is a risk of an accident.Always observe the traffic conditions care-fully, and maintain a safe lateral distance.

Active Lane Keeping Assist

General notes

Active Lane Keeping Assist monitors the area infront of your vehicle by means of multifunctioncamera: at the top of the windshield. Variousdifferent areas to the front, rear and side of yourvehicle are also monitored with the aid of theradar sensor system. Active Lane KeepingAssist detects lane markings on the road andcan warn you before you leave your lane unin-tentionally. If you do not react to the warning, a

lane-correcting application of the brakes canbring the vehicle back into the original lane.This function is available in a speed rangebetween 40 mph and 120 mph (60 km/h and200 km/h).For Active Lane Keeping Assist to assist youwhen driving, the radar sensor system must beoperational.

Important safety notesIf you fail to adapt your driving style, Active LaneKeeping Assist can neither reduce the risk ofaccident nor override the laws of physics. ActiveLane Keeping Assist cannot take into accountroad, weather or traffic conditions. Active LaneKeeping Assist is only an aid. You are responsi-ble for the distance to the vehicle in front, forvehicle speed, for braking in good time and forstaying in your lane.Active Lane Keeping Assist cannot continuouslykeep your vehicle in its lane.

G WARNINGActive Lane Keeping Assist cannot alwaysclearly detect lane markings.In such cases, Active Lane Keeping Assistcan:Rgive an unnecessary warning and thenmake a course-correcting brake applicationto the vehicleRnot give a warning or interveneThere is a risk of an accident.Always pay particular attention to the trafficsituation and keep within the lane, especiallyif Active Lane Keeping Assist alerts you. Ter-minate the intervention in a non-critical driv-ing situation.

The systemmay be impaired ormay not functionif:Rthere is poor visibility, e.g. due to insufficientillumination of the road, or due to snow, rain,fog or sprayRthere is glare, e.g. from oncoming traffic, thesun or reflection from other vehicles (e.g. ifthe road surface is wet)Rthewindshield is dirty, fogged up, damaged orcovered, for instance by a sticker, in the vicin-ity of the camera

G WARNINGActive Lane Keeping Assist does not detecttraffic conditions or road users. In very rarecases, the systemmaymake an inappropriate

brake application, e.g. after intentionally driv-ing over a solid lane marking. There is a risk ofan accident.An inappropriate brake application may beinterrupted at any time if you steer slightly inthe opposite direction. Alwaysmake sure thatthere is sufficient distance on the side forother traffic or obstacles.

If you leave your lane, under certain circumstan-ces the vehicle will brake briefly on one side.This ismeant to assist you in bringing the vehicleback to the original lane.If a lane-correcting brake application occurs,display: appears in the multifunction display.A lane-correcting brake application can bemadeafter driving over a lane marking recognized asbeing solid or broken. Before this, a warningmust be given bymeans of intermittent vibrationin the steering wheel. In addition, a lane withlane markings on both sides must be recog-nized.In the case of a broken lane marking beingdetected, a lane-correcting brake applicationcan only be made if a vehicle has been detectedin the adjacent lane. The following vehicles canhave an influence on brake application: oncom-ing traffic, vehicles that are overtaking and vehi-cles that are driving parallel to your vehicle.

i A further lane-correcting brake applicationcan only occur after your vehicle has returnedto the original lane.

No lane-correcting brake application occurs if:Ryou clearly and actively steer, brake or accel-erate.Ryou cut the corner on a sharp bend.Ryou have switched on the turn signal.

Off-road driving systems

4MATIC (permanent four-wheel drive)4MATIC ensures that all four wheels are perma-nently driven. Together with ESP® and 4ETS, itimproves the traction of your vehicle whenevera drive wheel spins due to insufficient grip.If you fail to adapt your driving style, 4MATIC canneither reduce the risk of accident nor overridethe laws of physics. 4MATIC cannot takeaccount of road, weather and traffic conditions.4MATIC is only an aid. You are responsible forthe distance to the vehicle in front, for vehiclespeed, for braking in good time and for staying inyour lane.

! Never tow the vehicle with one axle raised.This may damage the transfer case. Damageof this sort is not covered by the Mercedes-Benz Limited Warranty. All wheels mustremain either on the ground or be fully raised.Observe the instructions for towing the vehi-cle with all wheels in full contact with theground.

DSR (Downhill Speed Regulation)

General notesDSR is an aid to assist you when driving down-hill. It keeps the speed of travel at the speedselected on the on-board computer. The steeperthe downhill gradient, the greater the DSR brak-ing effect on the vehicle. When driving on flatstretches of road or on an uphill gradient, theDSR braking effect is minimal or nonexistent.DSR controls the vehicle’s speed when it is acti-vated and the transmission is in position D, R orN. You can drive at a higher or a lower speedthan that set on the on-board computer at anytime by accelerating or braking.

Important safety notesG WARNINGIf the speed driven and the set speed deviateand you activate DSR on a slippery road sur-face, the wheelsmay lose traction. There is anincreased danger of skidding and accidents.Before switching DSR on, please take intoconsideration the road surface and the differ-ence between driving speed and the setspeed.

If you fail to adapt your driving style, DSR canneither reduce the risk of accident nor overridethe laws of physics. DSR cannot take account ofroad, weather and traffic conditions. DSR is onlyan aid. You are responsible for the distance tothe vehicle in front, for vehicle speed, for brak-ing in good time and for staying in your lane.You are always responsible for keeping controlof the vehicle and for assessing whether thedownhill gradient can bemanaged. DSRmay notalways be able to keep to the set speed, depend-

ing on road surface and tire conditions. Select aset speed suitable for the prevailing conditionsandwhen necessary, apply the brakesmanually.

Activating DSR

RDo not install hired trailer couplings or otherdetachable trailer couplings on the bumpersof your vehicle.RIf you no longer need the ball coupling,remove it from the ball coupling recess. Thiswill reduce the risk of damage to the ball cou-pling.

When towing a trailer, set the tire pressure onthe rear axle of the towing vehicle for the max-imum load. You will find the values in the tirepressure table in the fuel filler flap of the vehicle(Y page 364).Please note that when towing a trailer, the fol-lowing driving systems have limited availabilityor are not available at all:RParking Assist PARKTRONIC (Y page 190)RBlind Spot Assist (Y page 207)RActive Lane Keeping Assist (Y page 213)On vehicles without level control, the height ofthe ball coupling will alter according to the loadplaced on the vehicle. If necessary, use a trailerwith a height-adjustable drawbar.You will find installing dimensions and loadsunder "Technical data" (Y page 387).

Driving tipsObserve the information on ESP® trailer stabili-zation (Y page 68) and on pulling away with atrailer (Y page 141).The maximum permissible speed for vehicle/trailer combinations depends on the type oftrailer. Before beginning the journey, check thetrailer's documents to see what the maximumpermissible speed is. Observe the legally pre-scribedmaximum speed in the relevant country.For certain Mercedes-Benz vehicles, the maxi-mum permissible rear axle load is increasedwhen towing a trailer. See "Technical data" tofind out whether this applies to your vehicle(Y page 387). If you utilize any of the addedmaximum rear axle load when towing a trailer,the vehicle/trailer combination may not exceeda maximum speed of 60 mph (100 km/h) forreasons concerning the operating permit. Thisalso applies in countries in which the permissi-ble maximum speed for vehicle/trailer combi-nations is above 60 mph (100 km/h).When towing a trailer, your vehicle's handlingcharacteristics will be different in comparisonwith when driving without a trailer.

Use the left-hand steering wheel paddle shifterto shift into a lower gear in good time on longand steep downhill gradients.This also applies if you have activated cruisecontrol or Distance Pilot DISTRONIC.This will use the braking effect of the engine, sothat less braking will be required tomaintain thespeed. This relieves the load on the brake sys-tem and prevents the brakes from overheatingand wearing too quickly. If you need additionalbraking, depress the brake pedal repeatedlyrather than continuously.

Driving tipsIf the trailer swings from side to side:X Do not accelerate.X Do not counter-steer.X Brake if necessary.RMaintain a greater distance from the vehiclein front than when driving without a trailer.RAvoid braking abruptly. If possible, brake gen-tly at first to allow the trailer to run on. Then,increase the braking force rapidly.RThe values given for gradient-climbing capa-bilities from a standstill refer to sea level.When driving in mountainous areas, note thatthe power output of the engine and, conse-quently, the vehicle's gradient-climbing capa-bility, decreases with increasing altitude.

Installing the ball coupling

X Secure the bolt using spring cotterB.

X Check the ball coupling, bolt and spring cotterfor correct installation.

If the ball coupling cannot be correctlymounted,remove the ball coupling. Under these circum-stances, the ball coupling must not be used fortrailer towing.Have the entire trailer tow hitch checked at aqualified specialist workshop.

Coupling up a trailer! Do not connect the trailer's brake system (iffeatured) to the hydraulic brake system of thetowing vehicle, as the latter is equipped withan anti-lock brake system. Doing so will resultin a loss of function of the brake systems ofboth the vehicle and the trailer.

X Shift the transmission to position P.X Apply the vehicle's electric parking brake.X Start the engine.X Vehicles with AIRMATIC package: selectnormal level and the Comfort drive program.

X Switch off the engine.X Close the doors and tailgate.X Couple up the trailer.

X Establish the electrical connection betweenthe vehicle and the trailer.

X Check that the trailer lighting system is work-ing.

X Push the combination switch upwards/down-wards and check whether the correspondingturn signal on the trailer flashes.

A trailer that is connected is recognized onlywhen the electrical connection is establishedcorrectly and when the lighting system is work-ing properly. The function of other systems alsodepends on this, for example:RESP®RParking Assist PARKTRONICRParking PilotRActive Blind Spot AssistRActive Lane Keeping Assist

i Vehicles with the AIRMATIC package: if youcouple up a trailer, the vehicle always remainsat normal level. When coupling up a trailer,please observe the following:RIf the normal level has not been set man-ually, the vehicle is automatically loweredto normal level. This is the case if a speed of5 mph (8 km/h) is reached.RThe Sport drive program is not available.These restrictions apply to all accessoriespowered through a connection to the trailerpower socket of your vehicle, e.g. a bicyclecarrier.

Observe the maximum permissible trailerdimensions (width and length).Most U.S. states and all Canadian provincesrequire by law:RSafety chains between the towing vehicle andthe trailer. The chains should be cross-woundunder the trailer drawbar. They must be fas-tened to the vehicle's trailer coupling, not tothe bumper or the axle.Leave enough play in the chains to make tightcornering possible.RA separate brake system for certain types oftrailer.RSafety switch for braked trailers. Check thespecific legal requirements applicable to yourstate.If the trailer becomes detached from the tow-ing vehicle, the safety switch applies thetrailer brakes.

Towing a trailerThere are numerous legal requirements con-cerning the towing of a trailer, e.g. speed restric-tions. Make sure that your car/trailer combina-tion complies with the local regulations:Rin your place of residenceRin the location to which you are drivingThe police and local authorities can provide reli-able information.Observe the following when towing a trailer:RTo gain driving experience and to becomeaccustomed to the new handling characteris-tics, you should practice the following in atraffic-free location:- cornering- stopping- backing upRBefore driving, check:

- trailer tow hitch- safety switch for braked trailers- safety chains- electrical connections- lights- wheelsRAdjust the exterior mirrors to provide anunobstructed view of the rear section of thetrailer.RIf the trailer has electronically controlledbrakes, pull away carefully. Brake manuallyusing the brake controller and check whetherthe brakes function correctly.RSecure any objects on the trailer to preventthe cargo from slipping when the vehicle is inmotion.RWhen you couple up a trailer, check at regularintervals that the load is firmly secured. If thetrailer is equipped with trailer lights andbrakes, check the trailer to ensure that theseare working.RBear in mind that the handling will be lessstable when towing a trailer than when drivingwithout one. Avoid sudden steering move-ments.RThe vehicle/trailer combination is heavier,accelerates more slowly, has a decreasedgradient climbing capability and a longerbraking distance.It is more susceptible to side winds andrequires more careful steering.

RIf possible, do not brake suddenly, but insteaddepress the brake pedalmoderately at first sothat the trailer can activate its brakes. Thenincrease the pressure on the brake pedal.RIf the automatic transmission repeatedlyshifts between gears on uphill or downhill gra-dients, shift to a lower gear using the left-handsteering wheel paddle shifter.A lower gear and lower speed reduce the riskof engine failure.RWhen driving downhill, shift to a lower gear toutilize the engine's braking effect.Avoid continuous brake application as thismay overheat the vehicle brakes and, if instal-led, the trailer brakes.RIf the coolant temperature increases dramat-ically while the air-conditioning system isswitched on, switch off the air-conditioningsystem.Coolant heat can also be dissipated by open-ing the windows and switching the ventilationblower and the interior temperature to thehighest level.RWhen overtaking, pay particular attention tothe extended length of your vehicle/trailercombination.Due to the length of the vehicle/trailer com-bination, you require additional road space inrelation to the vehicle you are overtakingbefore you can change back to the originallane.

Decoupling a trailer

G WARNINGIf you uncouple a trailer with the overrunbrake engaged, you could trap your handbetween the vehicle and the trailer drawbar.There is a risk of injury.Do not uncouple a trailer if the overrun brakeis engaged.

X Switch off the engine.

Permissible trailer loads and drawbarloads

Weight specifications

Maximum allowable gross massThe gross vehicle weight of the trailer is calcu-lated by adding the weight of the trailer to theweight of the load and equipment on the trailer.You will find installing dimensions and loadsunder "Technical data" (Y page 387).

Permissible noseweightYou will find installing dimensions and loadsunder "Technical data" (Y page 387).

Loading a trailerRWhen loading the trailer, make sure that nei-ther the permissible grossweight of the trailernor the gross vehicle weight are exceeded.The permissible gross vehicle weight is indi-cated on the identification plate located onthe B-pillar on the driver's side of the vehicle.You can find themaximum permissible valueson the type plates of your vehicle and thetrailer. When calculating how much weight

the vehicle and trailer may carry, pay atten-tion to the respective lowest values.RThe trailer drawbar load on the ball couplingmust be added to the rear axle load to avoidexceeding the permissible gross axle weight.The permissible gross vehicle weight is indi-cated on the identification plate located onthe B-pillar on the driver's side of the vehicle.

i Mercedes-Benz recommends a trailer loadwhere the trailer drawbar noseweightaccounts for 8 % to 15 % of the trailer's per-missible gross weight.

i The weight of additional accessories, pas-sengers, and cargo reduces the permissibletrailer load and drawbar load for your vehicle.

Checking the vehicle and trailer weightRTo check that the weights of the towing vehi-cle and the trailer comply with the maximumpermissible values, have the vehicle/trailercombination (including the driver, passen-gers, and cargo with a fully laden trailer)weighed on a calibrated weighbridge.RCheck the gross axle weight rating of the frontand rear axles, the gross weight of the trailerand the trailer drawbar noseweight.
