After a malfunction has been rectified, the infor-mation is deleted from the malfunction memoryor is continually overwritten.When operating the vehicle, situations are con-ceivable in which this technical data, in connec-tion with other information (if necessary, underconsultation with an authorized expert), couldbe traced to a person.Examples include:Raccident reportsRdamage to the vehicleRwitness statementsFurther additional functions that have been con-tractually agreed upon with the customer allowcertain vehicle data to be conveyed by the vehi-cle as well. The additional functions include, forexample, vehicle location in case of an emer-gency.

COMAND/mbraceIf the vehicle is equipped with COMAND ormbrace, additional data about the vehicle'soperation, the use of the vehicle in certain sit-uations, and the location of the vehicle may becompiled through COMAND or the mbrace sys-tem.For additional information please refer to theCOMAND User Manual or the Digital Operator'sManual and/or the mbrace Terms and Condi-tions.

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/fastened

RHow 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, andspecial equipment is required. In addition to thevehicle manufacturer, other parties that havethe special equipment, such as law enforce-ment, can read the information by accessing thevehicle or the EDR.EDR data may be used in civil and criminal mat-ters as a tool in accident reconstruction, acci-dent claims and vehicle safety. Since the CrashData Retrieval CDR tool that is used to extractdata from the EDR is commercially available,Mercedes-Benz USA, LLC ("MBUSA") expresslydisclaims any and all liability arising from theextraction of this information by unauthorizedMercedes-Benz personnel.MBUSA will not share EDR data with otherswithout the consent of the vehicle owners or, ifthe vehicle is leased, without the consent of thelessee. Exceptions to this representationinclude responses to subpoenas by law enforce-ment; by federal, state or local government; inconnectionwith or arising out of litigation involv-ing MBUSA or its subsidiaries and affiliates; or,as required by law.Warning: The EDR is a component of theRestraint SystemModule. Tamperingwith, alter-ing, modifying or removing the EDR componentmay result in a malfunction of the Restraint Sys-tem Module and other systems.State laws or regulations regarding EDRs thatconflict with federal regulation are pre-empted.Thismeans that in the event of such conflict, thefederal regulation governs. As of February 2013,13 states have enacted laws relating to EDRs.

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 42)Rhave adjusted their seat and head restraintproperly (Y page 89).

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 89).You also have to make sure that an air bag caninflate properly if deployed (Y page 44).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 51).For information on children traveling with you inthe vehicle and on child restraint systems, see"Children in the vehicle" (Y page 53).

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.

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 46) and on "Chil-dren in the vehicle" (Y page 53). 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 46). Be sure toobserve the notes on "Seatbelts“ (Y page 40) and "Air bags"(Y page 44). 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 rearRSeat belt force limiters for the front seat beltsand the outer seat belts in the rear

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 cause

injuries, 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-cle. The child restraint systemmust be appro-priate to the age, weight and size of the childRalways observe the instructions and safetynotes on "Children in the vehicle"(Y page 53) in addition to the child restraint

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.Sports seat or AMG Performance seat: thisseat is designed for the standard three-pointseat belt. If you install another multi-point seatbelt, e.g. sport or racing seat belts, the restraintsystem cannot provide the best level of protec-tion.

G WARNINGIf you feed seat belts through the opening inthe seat backrest, the seat backrest may bedamaged or may even break in the event of anaccident. This poses an increased risk ofinjury or even fatal injury.

Only use the standard three-point seat belt.Never modify the seat belt system.

Proper use of the seat beltsObserve the safety notes on the seat belt(Y page 41).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.

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 51).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 ofthe 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 the

door 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 40).RAlways observe the instructions and safetynotes on the "Occupant Classification System(OCS)" (Y page 46) and on "Children in thevehicle" (Y page 53) 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 40).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 46). ThePASSENGER AIR BAG OFF indicator lamp isnot lit (Y page 47)Rthe restraint system control unit predicts ahigh accident severity

Knee bags

Driver's knee bag: deploys under the steeringcolumn and front-passenger knee bag; underthe glove box. The driver's and front-passengerknee bags are triggered together with the frontair bags.The driver's and front-passenger knee bagsoffer additional thigh, knee and lower leg pro-tection for the occupants in the front seats.

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 rear sideimpact air bags; deploy next to the outer bol-ster 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 seat belt buckle tongue is engaged in thebelt buckle of 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 independentof 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 deployed in thearea from the A-pillar to the C-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 51).

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 and front-passenger knee bag areeither enabled or deactivated.The system does not deactivate:Rthe side impact air bagRthe window curtain air bagRthe Emergency Tensioning Devices

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 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, in the event of anaccident, the child could: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.Always move the front-passenger seat as farback as possible and fully retract the seatcushion length. Always make sure that theshoulder belt strap is correctly routed fromthe vehicle belt sash guide to the shoulder

belt guide on the child restraint system. Theshoulder belt strap must be routed forwardsand downwards from the vehicle belt sashguide. If necessary, adjust the vehicle beltsash guide and the front-passenger seataccordingly. Always observe the childrestraint system manufacturer's installationinstructions.

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.Rthe front-passenger seat is occupied by a per-son of smaller stature (e.g. a teenager orsmall adult), the PASSENGER AIR BAG OFFindicator lamp lights up and remains lit afterthe system self-test depending on the resultof the classification or, alternatively, goes out.- If the PASSENGER AIR BAG OFF indicatorlamp is off, move the front-passenger seatas far back as possible. Alternatively, a per-son of smaller stature can sit on a rear seat.

- If the PASSENGER AIR BAG OFF indicatorlamp is lit, a person of smaller statureshould not use the front-passenger seat.

Rthe front-passenger seat is occupied by anadult or a person of adult stature, thePASSENGER AIR BAG OFF indicator lampgoes out after the system self-test. This indi-cates that the front-passenger front air bag isactivated.

and to have any malfunctioning air bagsrepaired. 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.

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 40)Rthe seat belt buckle tongue has engaged inthe belt buckle of the respective front 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 as well as driver's and front-passenger knee bagsRWindow 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 40).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-sive role in the deployment of an air bag. Nor dothey provide an indication of air bag deploy-ment.The vehicle can be deformed considerably, with-out an air bag being deployed. This is the case ifonly parts which are relatively easily deformedare affected and the rate of deceleration is nothigh. Conversely, air bagsmay be deployed eventhough the vehicle suffers only minor deforma-tion. This is the case if, for example, very rigidvehicle parts such as longitudinal body mem-bers are hit, and sufficient deceleration occursas a result.If the restraint system control unit detects a sideimpact or if the vehicle rolls over, the applicablecomponents of the restraint system are activa-ted independently of each other depending onthe apparent type of accident.RSide impact air bags on the side where theimpact takes place, independently of theEmergency Tensioning Device and the use ofthe seat belt on the driver's seat and outerseats in the second rowThe side impact air bag on the front-passenger side deploys under the followingconditions:- the OCS system detects that the front-passenger seat is occupied or

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 60)RBAS (Brake Assist System) (Y page 60)RActive Brake Assist (Y page 61)RESP® (Electronic Stability Program)(Y page 63)REBD (Electronic Brake force Distribution)(Y page 66)RADAPTIVE BRAKE (Y page 66)RSTEER CONTROL (Y page 66)

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. Please pay special attention to thenotes on tires, recommended minimum tiretread depths, etc. (Y page 282).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 60).

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 218) and dis-play messages which may be shown in theinstrument cluster (Y page 189).

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.

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.

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 60).

Active Brake Assist consists of a distance warn-ing function with an autonomous braking func-tion and braking assistance appropriate to thesituation.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 supports you with brakingassistance appropriate to the situation.

Important safety notesDetection of hazardous situations can be par-ticularly impaired by:Rthere is dirt on the sensors or anything elsecovering the sensorsRthere is snow or heavy rainRthere is interference by other radar sources

Rthere 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 important safety notes in the"Breaking-in notes" section (Y page 120).

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 lowspeeds where no visible damage to the front ofthe vehicle is apparent.

Activating/deactivatingActive Brake Assist is active after every ignitioncycle.You can activate or deactivate Active BrakeAssist (Y page 182) 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.

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 60).

G WARNINGThe distance warning function does not react:Rto people or animalsRto oncoming vehiclesRto crossing trafficRwhen cornering

Thus, 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 approximately 4 mph(7 km/h), the distance warning function warnsyou if you rapidly approach a vehicle in front. Anintermittent warning tone will then sound, andthe· distance warning lamp will light up inthe instrument 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 approximately 44 mph(70 km/h), the distance warning function canalso react to stationary obstacles, such as stop-ped or parked vehicles.

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:Rgives the driver more time to react to criticaldriving situationsRcan help the driver to avoid an accident orRreduces the effects of an accidentVehicles without Distance Pilot DISTRONIC: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

Vehicles with Distance Pilot DISTRONIC: theautonomous braking function is available in thefollowing speed ranges:R4 - 124 mph (7 - 200 km/h) for movingobjectsR4 - 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.

Braking assistance appropriate to thesituation

General informationi Observe the "Important safety notes" sec-tion (Y page 60).

With the help of the radar sensor system, Adap-tive BrakeAssist can detect obstacles that are inthe path of your vehicle for an extended periodof time.If Adaptive Brake Assist detects a risk of colli-sion with the vehicle in front, it calculates thebrake pressure necessary to avoid a collision. Ifyou apply the brakes forcefully, the brakingassistance adapts to the situation and automat-ically increases the brake pressure to a degreeappropriate to the traffic situation.Braking assistance appropriate to the situationprovides braking assistance in hazardous situa-tions at speeds above 4 mph (7 km/h). It usesradar sensor technology to assess the trafficsituation.Situation-dependent braking assistance is capa-ble of reacting to moving objects that havealready been recognized as such at least onceover the period of observation, up to vehiclespeeds of around 155 mph (250 km/h).

Page 65: CLA - Mercedes-Benz USA · WelcometotheworldofMercedes-Benz WeurgeyoutoreadthisOperator'sManual carefullyandfamiliarizeyourselfwiththevehi-clebeforedriving.Foryourownsafetyanda

Braking assistance appropriate to the situationcan also detect stationary objects, up to vehiclespeeds of around 44 mph 70 km/h.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.

Braking assistance appropriate to the situationis then deactivated.

Important safety notesi Observe the "Important safety notes" sec-tion for driving safety systems (Y page 60).

G WARNINGAdaptive Brake Assist does not react:Rto people or animalsRto oncoming vehiclesRto crossing trafficRwhen corneringAs a result, 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.

G WARNINGAdaptive Brake Assist cannot always clearlyidentify objects and complex traffic situa-tions.In such cases, Adaptive Brake Assist might: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.

Due to the nature of the system, complex butnon-critical driving conditions may also causeActive Brake Assist to intervene.Even if Active Brake Assist is not available due toa malfunction in the radar sensor system, the

brake system is still available with full brakeboosting effect and BAS.

ESP® (Electronic Stability Program)

General notesi Observe the "Important safety notes" sec-tion (Y page 60).

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)i Observe the "Important safety notes" sec-tion (Y page 60).

ETS traction control is part of ESP®. On vehicleswith 4MATIC, 4ETS 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®.

Important safety notesi Observe the "Important safety notes" sec-tion (Y page 60).

G WARNINGIf ESP® is malfunctioning, ESP® is unable tostabilize the vehicle. Additionally, further driv-ing safety systems are deactivated. Thisincreases the risk of skidding and an accident.Drive on carefully. Have ESP® checked at aqualified specialist workshop.

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. Once thesystem no longer detects any other vehicles, itreactivates the high-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 berestricted if there is: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

The air-conditioning system or dual-zone auto-matic climate control regulates the temperatureand the humidity of the vehicle interior and fil-ters undesirable substances from the air.The air-conditioning system or dual-zone auto-matic climate control can only be operatedwhen the engine is running. Optimum operationis only achieved with the side windows and pan-orama roof with power tilt/sliding panel closed.If you start the engine using your smartphone,the last selected climate control setting is reac-tivated (Y page 122).The residual heat function can only be activatedor deactivated with the ignition switched off(Y page 118).

Always keep the ventilation flaps behind theside trim panel in the cargo compartment clear(Y page 105). Otherwise the vehicle will not beventilated correctly.

i Ventilate the vehicle for a brief period duringwarm weather, e.g. using the convenienceopening feature (Y page 82). This will speedup the cooling process and the desired inte-rior temperature will be reached morequickly.

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 It is possible that under certain circumstan-ces the residual heat function may be activa-ted automatically an hour after the SmartKeyhas been removed in order to dry the auto-matic climate control. The vehicle is then ven-tilated for 30 minutes.

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).RIdeally, for the first 1000 miles (1500 km),drive in program E.

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.After 1,000 miles (1,500 km), you can increasethe engine speed gradually and bring the vehicleto 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.

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.

G WARNINGIf you operate mobile communication equip-ment while driving, you will be distracted fromtraffic conditions. You could also lose controlof the vehicle. There is a risk of an accident.Only operate this equipment when the vehicleis stationary.

Observe the legal requirements for the countryin which you are driving. Some jurisdictions pro-hibit the driver from using a mobile phone whiledriving a vehicle.If you make a call while driving, always usehands-free mode. Only operate the telephonewhen the traffic situation permits. If you areunsure, pull over to a safe location and stopbefore operating the telephone.Bear in mind that at a speed of only 30 mph(approximately 50 km/h), the vehicle covers adistance of 44 ft (approximately 14 m) per sec-ond.

Drive sensibly – save fuelObserve the following tips to save fuel:RThe tires should always be inflated to the rec-ommended tire pressure.RRemove unnecessary loads.RRemove roof racks when they are not needed.RWarm up the engine at low engine speeds.RAvoid frequent acceleration or braking.RHave all maintenance work carried out asindicated by the service intervals in the Main-

tenance Booklet or by the service interval dis-play.

Fuel consumption also increaseswhen driving incold weather, in stop-start traffic and in hilly ter-rain.

Drinking and driving

G WARNINGDrinking and driving and/or taking drugs anddriving are very dangerous combinations.Even a small amount of alcohol or drugs canaffect your reflexes, perceptions and judg-ment.The possibility of a serious or even fatal acci-dent is greatly increased when you drink ortake drugs and drive.Do not drink or take drugs and drive or allowanyone to drive who has been drinking or tak-ing drugs.

Emission control

G WARNINGCombustion engines emit poisonous exhaustgases such as carbon monoxide. Inhalingthese exhaust gases leads to poisoning. Thereis a risk of fatal injury. Therefore never leavethe engine running in enclosed spaces with-out sufficient ventilation.

Certain engine systems are designed to keepthe level of poisonous components in exhaustfumes within legal limits.These systems only work at peak efficiency ifthey are serviced exactly in accordance with themanufacturer's specifications. Always havework on the engine carried out at a qualifiedspecialist workshop. Mercedes-Benz recom-mends that you use an authorized Mercedes-Benz Center for this purpose. In particular, workrelevant to safety or on safety-related systemsmust be carried out at a qualified specialistworkshop.The engine settings must not be changed underany circumstances. Furthermore, all specificservice work must be carried out at regularintervals and in accordance with the Mercedes-Benz service requirements. Details can be foundin the Maintenance Booklet.

ECO displayThe ECO display shows you how economicalyour driving style is. The ECO display assists youin achieving the most economical driving stylefor the selected settings and prevailing condi-tions. Your driving style can significantly influ-ence the vehicle's consumption.

: Acceleration; Coasting= Constant? Additional range achievedRange? is shownunder Bonus fr. Start andrepresents the additional range achieved sincethe beginning of the journey as a result of anadapted driving style.If the fuel level has dropped into the reserverange, the Fuel Low message is shown in themultifunction display instead of range?. The8 warning lamp in the instrument clusteralso lights up (Y page 222).

The ECO display consists of three sections, withan inner and outer area. The sections corre-spond to the following three categories:

: Acceleration (evaluation of theacceleration processes):Rthe outer area fills up and the innerarea lights up green: moderateacceleration, especially at higherspeedsRthe outer area empties and theinner area is gray: sporty acceler-ation

; Coasting (evaluation of all decelera-tion processes):Rthe outer area fills up and the innerarea lights up green: anticipatorydriving, keeping your distance andearly release of the accelerator.The vehicle can coast without useof the brakes.Rthe outer area empties and theinner area is gray: frequent heavybraking

= Constant(continuous evaluationover the entire journey):Rthe outer area fills up and the innerarea lights up green: constantspeed and avoidance of unneces-sary acceleration and decelerationRthe outer area empties and theinner area is gray: fluctuations inspeed

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. Start does notindicate a fixed consumption reduction.

In addition to driving style, the actual consump-tion is affected by other factors, such as:RLoadRTire pressureRCold startRChoice of routeRActive electrical consumersThese 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 drive program C or E(vehicles with a DYNAMIC SELECT button).

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 178).For more information on the ECO display, see(Y page 177).

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 engine braking. For this youmust first activate manual gearshifting. This

helps you to avoid overheating the brakes andwearing them out excessively.When you take advantage of engine braking, itis possible that a drivewheel will not rotate forsome time, e.g. on a slippery road surface.This could cause damage to the drive train.This type of damage is not covered by theMercedes-Benz warranty.

Briefly depressing the accelerator pedal ondownhill gradients while the manual drive pro-gram M is temporarily activated: the automatictransmission may switch to the last active auto-matic drive program E orS. The automatic trans-mission may shift to a higher gear. This canreduce the engine's braking effect.

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 firsttime. This may also occur after the vehicle hasbeen washed or driven through deep water.You 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.RIn order to prevent any salt build-up, apply thebrakes occasionally while paying attention tothe traffic conditions.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.

! As the ESP® system operates automatically,the engine and the ignition must be switchedoff (the SmartKeymust be in position 0 or 1 inthe ignition lock) if:Rthe electric parking brake is tested on abrake dynamometer (for a maximum often seconds)Rthe vehicle is towed with the front axleraised.

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.You can find a description of Brake Assist (BAS)on (Y page 60).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.

Checking brake lining thicknessYou can measure the break pad/lining thick-ness using a test gage. Color-coding (green orred) on the test gage allows you to determinewhether the brake pad/lining thickness is stillsufficient. The test gage is in the vehicle docu-ment wallet in the glove box.

To avoid an inaccurate measurement:Rmake sure you position the wheels suitablyRdo not put the measuring pin on a recess inthe brake disc

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 speedsRthe tires have adequate tread depthFor this reason, in the event of heavy rain or inconditions in which hydroplaning may occur,you must drive in the following manner:Rlower your speedRavoid rutsRavoid sudden steering movementsRbrake 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.

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 gasessuch 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.X Try to bring the vehicle under control usingcorrective steering.

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 pay special attention to road condi-tions when temperatures are around freezingpoint.For more information on driving with snowchains, see (Y page 285).For more information on driving with summertires, see (Y page 284).Observe the notes in the "Winter operation" sec-tion (Y page 284).

Driving systems

Cruise control

General notesCruise control maintains a constant road speedfor you. It brakes automatically in order to avoidexceeding the set speed. On long and steepdownhill gradients, especially if the vehicle isladen, you must select a low gear in good time.You need to have selected manual drive pro-gramM (Y page 135). By doing so, youwill makeuse of the braking effect of the engine. This

relieves the load on the brake system and pre-vents the brakes from overheating and wearingtoo quickly.When the engine is running, you can use thecruise control lever to limit the speed to anyspeed between 20mph (30 km/h) and the tech-nically permittedmaximumspeed of the vehicle.Use cruise control only if road and traffic con-ditions make it appropriate to maintain a steadyspeed for a prolonged period.The speed indicated in the speedometer maydiffer slightly from the speed stored.

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 to maintain 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 skidRin poor visibility, e.g. due to fog, heavy rain orsnow

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

Activation conditionsTo activate cruise control, all of the followingactivation conditions must be fulfilled:Rthe electric parking brake must be released.RESP® must be active, but not intervening.Rthe transmission must be in position D.

Storing, maintaining and calling up aspeed

Storing and maintaining the currentspeedYou can store the current speed if you are driv-ing faster than 20 mph (30 km/h).X Accelerate the vehicle to the desired speed.X Briefly press the cruise control lever up: ordown;.

X Remove your foot from the accelerator pedal.Cruise control is activated. The vehicle auto-matically maintains the stored speed.i Cruise control may be unable to maintainthe stored speed on uphill gradients. Thestored speed is resumed when the gradientevens out. Cruise control maintains thestored speed on downhill gradients by auto-matically applying the brakes.

Storing the current speed or calling up thelast stored 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 cruise control is activated, itstores the current speed or regulates thespeed of the vehicle to the previously storedspeed.

Setting a speedKeep in mind that it may take a brief momentuntil the vehicle has accelerated or braked tothe speed set.X To adjust the set speed in10 km/hincre-ments:briefly press cruise control lever: upbeyond the pressure point for a higher speed,or down; for a lower speed.

orX Keep the cruise control lever pressed beyondthe point of resistance until the desired speedis set. Press cruise control lever up: for ahigher speed or down; for a lower speed.

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 to avoid exceeding the set speed or tomaintain the designated distance from the vehi-cle in front.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.Distance Pilot DISTRONIC operates in the rangebetween 0 mph (0 km/h) and 120 mph(200 km/h).Change into a lower gear in good time on longand steep downhill gradients. This is especiallyimportant if the vehicle is laden. By doing so, youwill make use of the braking effect of the engine.This relieves the load on the brake system andprevents the brakes from overheating and wear-ing too quickly.Do not use Distance Pilot DISTRONIC on roadswith steep gradients.For Distance Pilot DISTRONIC to assist youwhen driving, the radar sensor system must beoperational.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.

Activating Distance Pilot DISTRONIC

Activation conditions! When Distance Pilot DISTRONIC or theHOLD function is activated, the vehiclebrakes automatically in certain situations.To avoid damage to the vehicle, deactivateDistance Pilot DISTRONIC and the HOLDfunction in the following or similar situations:Rwhen towing the vehicleRin the car wash

To 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.RParking Pilot must not be activated.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 must be closed.Rthe vehicle must not skid.

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

X Keep the cruise control lever pressed up: ordown; until the desired speed is set.

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).

Driving with Distance Pilot DISTRONIC

Activating 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 previ-ously stored speed.

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 If Distance Pilot DISTRONIC is activated: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. Be ready to brake at alltimes.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.

i Distance Pilot DISTRONIC is deactivatedwhen you depress the brake, except when thevehicle is stationary.

Selecting the drive programDistance Pilot DISTRONIC supports a sportydriving style when you select the S+ drive pro-gram (Mercedes-AMG vehicles only), S(Y page 133) or the manual drive program(Y page 135). Acceleration behind the vehicle infront or to the set speed is then noticeably moredynamic. If you have selected the E (Mercedes-AMG vehicles: C) drive program, the vehicleaccelerates more gently. This setting is recom-mended in stop-and-start traffic.

Changing lanesIf when driving on multilane roads you wish tochange to the overtaking lane, Distance PilotDISTRONIC supports you if:Ryou are driving faster than 45 mph (70 km/h)RDistance Pilot DISTRONIC is maintaining thedistance to a vehicle in frontRyou 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.

StoppingIf Distance Pilot DISTRONIC detects that thevehicle in front is stopping, it brakes your vehicleuntil it is stationary.Once your vehicle is stationary, it remains sta-tionary and you do not need to depress thebrake.

i After a time, the electric parking brakesecures the vehicle and relieves the servicebrake.

i Depending on the specified minimum dis-tance, your vehicle will come to a standstill ata sufficient distance behind the vehicle infront. The specified minimum distance is setusing the control on the cruise control lever.

When Distance Pilot DISTRONIC is activated,the transmission is shifted automatically toposition P if:Rthe driver's seat belt is not fastened and thedriver's door is open.Rthe engine is switched off, unless it is auto-matically switched off by the ECO start/stopfunction.

The electric parking brake secures the vehicleautomatically if Distance Pilot DISTRONIC isactivated when the vehicle is stationary and:Ra system malfunction occurs.Rthe power supply is insufficient.If a malfunction occurs, the transmission mayalso shift into position P automatically.

Setting a speedKeep in mind that it may take a brief momentuntil the vehicle has accelerated or braked tothe speed set.X Press the cruise control lever up: for ahigher speed or down; for a lower speed.

X To adjust the set speed in1 mphincre-ments (1 km/hincrements): briefly pressthe cruise control lever up: or down; tothe pressure point.The last stored speed increases or decreasesin 1 mph (1 km/h) increments.

X To adjust the set speed in5 mphincre-ments (10 km/hincrements): briefly pressthe cruise control lever up: or down; tothe pressure point.The last stored speed increases or decreasesin 5 mph (10 km/h) increments.

i Distance Pilot DISTRONIC is not deactivatedif you depress the accelerator pedal. If youaccelerate to overtake, Distance PilotDISTRONIC adjusts the vehicle's speed to thelast speed stored after you have finished over-taking.

Setting a specified minimum distanceYou can set the specified minimum distance forDistance Pilot DISTRONIC by varying the timespan between one and two seconds. With thisfunction you can set the minimum distance thatDistance Pilot DISTRONICmaintains to the vehi-cle in front, dependent on vehicle speed.

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.RDistance Pilot DISTRONIC may mistakenlydetect vehicles that are crossing your lane. Ifyou activate Distance Pilot DISTRONIC in thefollowing situations, the vehicle could pullaway unintentionally:- At traffic lights with crossing traffic, forexample.

- With a vehicle ahead on the other side of anintersection and the HOLD function active.

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

(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 the time has been set incorrectlyRin active driving situations, such as when youchange lanes or change your speed

ATTENTION ASSIST is reset when you continueyour journey and starts assessing your tirednessagain 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 182) ofthe on-board computer.X Select the Assistance display for AttentionAssist using the on-board computer(Y page 182).

The following information is displayed:RLength of the journey since the last break.RThe Attention Level determined by ATTEN-TION ASSIST, displayed in a bar display in fivelevels from high to lowRIf ATTENTION ASSIST is unable to calculatethe attention level and cannot output a warn-ing, the System Passive message appears.The bar display then changes the display,such aswhen you are driving at a speed below37 mph (60 km/h) or above 124 mph(200 km/h).

Activating ATTENTION ASSISTX Activate ATTENTION ASSIST using the on-board computer (Y page 183).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 sethigher. The attention level detected by AttentionAssist is adapted accordingly and the driver iswarned earlier.When ATTENTION ASSIST is deactivated, theé symbol appears in the multifunction dis-play in the assistance graphic display.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 properly. If you donot take a break and ATTENTION ASSIST stilldetects increasing lapses in concentration, youwill be warned again after 15 minutes at theearliest. This will only happen if ATTEN-TION ASSIST still detects typical indicators offatigue or increasing lapses in concentration.Vehicles with the COMAND multimedia sys-tem: if a warning is output in the multifunctiondisplay, a service station search is performed inthe multimedia system. You can select a servicestation and navigation to this service station willthen begin. This function can be activated ordeactivated in the multimedia system; see theDigital Operator's Manual.

Lane Tracking package

General notesThe Lane Tracking package consists of BlindSpot Assist (Y page 171) and Lane KeepingAssist (Y page 172).

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.

i USA only:This device has been approved by the FCC asa "Vehicular Radar System". The radar sensoris intended for use in an automotive radarsystem only. Removing, tampering with, oraltering the device will void any warranties,and is not permitted by the FCC. Do not tam-per with, alter, or use in any non-approvedway.Any unauthorized modification to this devicecould void the user’s authority to operate theequipment.

Radar sensorsThe radar sensors for Blind Spot Assist are inte-grated into the rear bumper. Make sure that thebumpers are free from dirt, ice or slush. Thesensors must not be covered, for example bycycle racks or overhanging loads. Following asevere impact or in the event of damage to thebumpers, have the function of the radar sensorschecked at a qualified specialist workshop.Blind Spot Assist may no longer work properly.

Monitoring range of the sensorsIn particular, the detection of obstacles can beimpaired if:Rthere is dirt on the sensors or anything elsecovering the sensorsRthere is poor visibility, e.g. due to fog, heavyrain or snowRa narrow vehicle traveling in front, e.g. amotorbike or bicycleRthe road has very wide lanesRthe road has narrow lanesRyou are not driving in the middle of the laneRthere are barriers or other road boundariesVehicles in the monitoring range are then notindicated.

Page 174: CLA - Mercedes-Benz USA · WelcometotheworldofMercedes-Benz WeurgeyoutoreadthisOperator'sManual carefullyandfamiliarizeyourselfwiththevehi-clebeforedriving.Foryourownsafetyanda

Blind Spot Assist monitors the area up to 10 ft(3 m) behind your vehicle and directly next to it.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 the vehicles are driving on the inner sideof their lane.Due to the nature of the system:Rwarnings may be issued in error when drivingclose to crash barriers or similar solid laneborders.Rwarnings may be interrupted when drivingalongside particularly long vehicles, e.g.trucks, for a prolonged time.

Warning display

: Warning displayBlind Spot Assist is not active at speeds belowapproximately 20 mph (30 km/h). Vehicles inthe monitoring range are then not indicated.When 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. If the turnsignal remains on, vehicles detected are indica-ted by the flashing of red warning lamp:.There are no further warning tones.

Switching on Blind Spot AssistX Make sure that Blind Spot Assist is activatedin the on-board computer (Y page 183).

X Turn the SmartKey to position2 in the ignitionlock.Warning lamps: in the exterior mirrors lightup red for approximately 1.5 seconds andthen turn yellow.

Lane Keeping Assist

General notes

LaneKeepingAssistmonitors the area in front ofyour vehicle by means of multifunction cam-era: which is attached behind the top of thewindshield. Active Lane Keeping Assist detectslane markings on the road and can warn youbefore you leave your lane unintentionally.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 snow

Rthe 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 highly variable shade conditions onthe roadway

Switching on Lane Keeping AssistX Switch on Active Lane Keeping Assist usingthe on-board computer; to do so, selectStandard or Adaptive (Y page 183).If you drive at speeds above 40 mph(60 km/h) and lane markings are detected,the lines in the assistance graphics display(Y page 182) are shown in green. Lane Keep-ing Assist is ready for use.

If Standard is selected, no warning vibrationoccurs if:Ryou have switched on the turn signal. In thisevent, the warnings are suppressed for a cer-tain period of time.Ra driving safety system intervenes, e.g. ABS,BAS or ESP®.

When Adaptive is selected, no warning vibra-tion occurs if:Ryou have switched on the turn signal.

General notes

The multimedia system section in this Opera-tor's Manual describes the basic principles foroperation. More information can be found in theDigital Operator's Manual.

Important safety notes

G WARNINGIf you operate information systems and com-munication equipment integrated in the vehi-cle while driving, you will be distracted fromtraffic conditions. You could also lose controlof the vehicle. There is a risk of an accident.Only operate the equipment when the trafficsituation permits. If you are not sure that thisis possible, park the vehicle paying attentionto traffic conditions and operate the equip-ment when the vehicle is stationary.

Youmust observe the legal requirements for thecountry in which you are currently driving whenoperating the multimedia system.The multimedia system calculates the route tothe destination without taking the following intoaccount, for example:Rtraffic lightsRstop and yield signsRparking or stopping restrictionsRroad narrowingRother road and traffic rules and regulationsThe multimedia system may give incorrect nav-igation recommendations if the actual street/traffic situation does not correspond with thedigital map's data.For example:Ra diverted routeRthe road layout or the direction of a one-waystreet has been changed

For this reason, you must always observe roadand traffic rules and regulations during yourjourney. Road and traffic rules and regulationsalways have priority over multimedia systemdriving recommendations.Navigation announcements are intended todirect you while driving without diverting yourattention from the road and driving.

Please always use this feature instead of con-sulting the map display for directions. Lookingat the icons ormap display can distract you fromtraffic conditions and driving, and increase therisk of an accident.This equipment complies with FCC radiationexposure limits set forth for uncontrolled equip-ment and meets the FCC radio frequency (RF)Exposure Guidelines in Supplement C to OET65.This equipment has very low levels of RF energythat is deemed to comply without maximumpermissive exposure evaluation (MPE). How-ever, it is recommended to install it at a distanceof at least 8 inches (approx. 20 cm) between theradiation source and a person's body (notincluding limbs such as hands, wrists, feet andlegs).

G WARNINGModifications to electronic components, theirsoftware as well as wiring can impair theirfunction and/or the function of other net-worked components. In particular, systemsrelevant to safety could also be affected. As aresult, these may no longer function as inten-ded and/or jeopardize the operating safety ofthe vehicle. There is an increased risk of anaccident and injury.Never tamper with the wiring as well as elec-tronic components or their software. Youshould have all work to electrical and elec-tronic equipment carried out at a qualifiedspecialist workshop.

If you make any changes to the vehicle elec-tronics, the general operating permit is ren-dered invalid.

Function restrictions

For safety reasons, some functions are restric-ted or unavailable while the vehicle is in motion.You will notice this, for example, because eitheryou will not be able to select certain menu itemsor a message will appear to this effect.

Make sure thatyou use the proper size and type (summer orwinter tire).Vehicles equipped with MOExtended tires arenot equipped with a TIREFIT kit at the factory. Itis therefore recommended that you additionallyequip your vehiclewith a TIREFIT kit if youmounttires that do not feature run-flat properties, e.g.winter tires. A TIREFIT kit may be obtained froma qualified specialist workshop.

Fuses

Important safety notes

G WARNINGIf you manipulate or bridge a faulty fuse or ifyou replace it with a fuse with a higher amper-age, the electric cables could be overloaded.This could result in a fire. There is a risk of anaccident and injury.Always replace faulty fuses with the specifiednew fuses having the correct amperage.

! Only use fuses that have been approved forMercedes-Benz vehicles and which have thecorrect fuse rating for the system concerned.Only use fuses marked with an "S". Other-

wise, components or systems could be dam-aged.

! Make sure that no moisture can enter thefuse box when the cover is open.

! When closing the cover, make sure that it islying correctly on the fuse box.Moisture seep-ing in or dirt could otherwise impair the oper-ation of the fuses.

The fuses in your vehicle serve to close downfaulty circuits. If a fuse blows, all the compo-nents on the circuit and their functions stopoperating.Blown fuses must be replaced with fuses of thesame rating, which you can recognize by thecolor and value. The fuse ratings are listed in thefuse allocation chart.The fuse allocation chart is in the fuse box in thefront-passenger footwell (Y page 280).If a newly inserted fuse also blows, have thecause traced and rectified at a qualified special-ist workshop, e.g. an authorizedMercedes-BenzCenter.

Before changing a fuseX Secure the vehicle against rolling away(Y page 140).

X Switch off all electrical consumers.X Vehicles without KEYLESS-GO: remove theSmartKey from the ignition lock.

Operation

Information on drivingCheck the tire pressure when the vehicle isheavily laden and adjust prior to a trip.While driving, pay attention to vibrations, noisesand unusual handling characteristics, e.g. pull-ing to one side. This may indicate that thewheels or tires are damaged. If you suspect thata tire is defective, reduce your speed immedi-ately. Stop the vehicle as soon as possible tocheck the wheels and tires for damage. Hiddentire damage could also be causing the unusualhandling characteristics. If you find no signs ofdamage, have the tires and wheels checked at aqualified specialist workshop.When parking your vehicle, make sure that thetires do not get deformed by the curb or otherobstacles. If they cannot be avoided, drive overobstacles such as curbs slowly and at an obtuseangle. Otherwise, you may damage the wheelsor tires.

Regular checking of wheels and tires

G WARNINGDamaged tires can cause tire inflation pres-sure loss. As a result, you could lose control ofyour vehicle. There is a risk of accident.Check the tires regularly for signs of damageand replace any damaged tires immediately.

Page 285: CLA - Mercedes-Benz USA · WelcometotheworldofMercedes-Benz WeurgeyoutoreadthisOperator'sManual carefullyandfamiliarizeyourselfwiththevehi-clebeforedriving.Foryourownsafetyanda

Checkwheels and tires for damage at least oncea month. Check wheels and tires after drivingoff-road or on rough roads. Damaged wheelscan cause a loss of tire pressure. Pay particularattention to damage such as:Rcuts in the tiresRpunctures in the tiresRtears in the tiresRbulges on tiresRdeformation or severe corrosion on wheelsRegularly check the tire tread depth and thecondition of the tread across the whole width ofthe tire (Y page 283). If necessary, turn thefront wheels to full lock in order to inspect theinner side of the tire surface.All wheels must have a valve cap to protect thevalve against dirt and moisture. Do not mountanything onto the valve other than the standardvalve cap or other valve caps approved byMercedes-Benz for your vehicle. Do not use anyother valve caps or systems, e.g. tire pressuremonitoring systems.Regularly check the pressure of all the tires par-ticularly prior to long trips. Adjust the tire pres-sure as necessary (Y page 285).The service life of tires depends, among otherthings, on the following factors:RDriving styleRTire pressureRDistance covered

Notes on tire tread

G WARNINGInsufficient tire tread will reduce tire traction.The tire is no longer able to dissipate water.This means that on wet road surfaces, the riskof hydroplaning increases, in particular wherespeed is not adapted to suit the driving con-ditions. There is a risk of accident.If the tire pressure is too high or too low, tiresmay exhibit different levels of wear at differ-ent locations on the tire tread. Thus, youshould regularly check the tread depth andthe condition of the tread across the entirewidth of all tires.

Minimum tire tread depth for:RSummer tires:â in (3 mm)RM+S tires:ã in (4 mm)For safety reasons, replace the tires beforethe legally prescribed limit for the minimumtire tread depth is reached.

Marking: shows where bar indicator; fortread wear is integrated into the tire tread.Treadwear indicators (TWI) are required by law.Six indicators are positioned on the tire tread.They are visible once a tread depth of approx-imatelyá in (1.6mm) has been reached. If thisis the case, the tire is so worn that it must bereplaced.

Selecting, mounting and replacingtires

G WARNINGExceeding the stated tire load-bearing capa-city and the approved maximum speed couldlead to tire damage or the tire bursting. Thereis a risk of accident.Therefore, only use tire types and sizesapproved for your vehicle model. Observe thetire load rating and speed rating required foryour vehicle.

ROnly mount tires and wheels of the same typeand make.Exception: it is permissible to install a differ-ent type or make in the event of a flat tire.Observe here the "MOExtended tires (tires

The new tires onlyreach their full performance after this dis-tance.RDo not drive with tires which have too littletread depth, as this significantly reduces thetraction on wet roads (hydroplaning).RReplace the tires after six years at the latest,regardless of wear.

MOExtended tires (tires with run-flatproperties)With MOExtended tires (tires with run flat char-acteristics), you can continue to drive your vehi-cle even if there is a total loss of pressure in oneor more tires.MOExtended tires may only be used in conjunc-tion with an activated tire pressure loss warningsystem (Canada only) or tire pressure monitor(USA only) and only on wheels specifically tes-ted by Mercedes-Benz.Notes on driving with MOExtended tires with aflat tire (Y page 267).Vehicles equipped with MOExtended tires arenot equipped with a TIREFIT kit at the factory. Itis therefore recommended that you additionallyequip your vehiclewith a TIREFIT kit if youmounttires that do not feature run-flat properties, e.g.winter tires. A TIREFIT kit may be obtained froma qualified specialist workshop.

Winter operation

General notesHave your vehicle winter-proofed at a qualifiedspecialist workshop at the onset of winter.Observe the notes in the "Changing a wheel"section (Y page 301).

Driving with summer tiresAt temperatures below 45 ‡ (+7 †), summertires lose elasticity and therefore traction andbraking power. Change the tires on your vehicleto M+S tires. Using summer tires at very cold

temperatures could cause cracks to form,thereby damaging the tires permanently.Mercedes-Benz cannot accept responsibility forthis type of damage.

G WARNINGDamaged tires can cause tire inflation pres-sure loss. As a result, you could lose control ofyour vehicle. There is a risk of accident.Check the tires regularly for signs of damageand replace any damaged tires immediately.

M+S tires

G WARNINGM+S tires with a tire tread depth of less thanã in (4 mm) are not suitable for use in winterand do not provide sufficient traction. There isa risk of an accident.M+S tires with a tread depth of less thanã in(4 mm) must be replaced immediately.

At temperatures below 45 ‡ (+7†), use wintertires or all-season tires. Both types of tire areidentified by the M+S marking.Only winter tires bearing thei snowflakesymbol in addition to the M+S marking providethe best possible grip in wintry road conditions.Only these tires will allow driving safety systemssuch as ABS and ESP® to function optimally inwinter. These tires have been developed specif-ically for driving in snow.UseM+S tires of the samemake and tread on allwheels to maintain safe handling characteris-tics.Always observe the maximum permissiblespeed specified for the M+S tires you havemounted.When you have mounted the M+S tires:X Check the tire pressures (Y page 285).X Restart the tire pressure monitor (USA only)(Y page 291).

Snow chains

G WARNINGIf snow chains are mounted on the rearwheels, the snow chains could cause abrasionto the vehicle body or to chassis components.This could cause damage to the vehicle or thetires. There is a risk of an accident.To avoid hazardous situations:Rnever mount snow chains on the rearwheelsRonly mount snow chains in pairs on thefront wheels.

! Onsome tire sizes there is not enough spacefor snow chains. To avoid damage to the vehi-cle or tires, observe the "Wheel and tire com-binations" section under "Tires and wheels".

For safety reasons, Mercedes-Benz recom-mends that you only use snow chains that havebeen specially approved for your vehicle byMercedes-Benz, or are of a correspondingstandard of quality. For more information,please contact a qualified specialist workshop.If you intend to mount snow chains, please bearthe following points in mind:RSnow chains may not be mounted on allwheel/tire combinations. Permissible wheel-tire combinations (Y page 306).ROnly use snow chains when driving on roadscompletely covered by snow. Remove thesnow chains as soon as possible when youcome to a road that is not snow-covered.RLocal regulationsmay restrict the use of snowchains. Observe the appropriate regulations ifyou wish to mount snow chains.RDo not exceed the maximum permissiblespeed of 30 mph (50 km/h).RDo not use Parking Pilot when snow chainsare installed (Y page 162).

You may wish to deactivate ESP® (Y page 63)when pulling away with snow chains installed .You can thereby allow the wheels to spin in acontrolled manner, achieving an increased driv-ing force (cutting action).

Tire and Loading Information placard

: Recommended tire pressuresThe Tire and Loading Information placard is onthe B-pillar on the driver's side (Y page 292).The Tire and Loading Information placard con-tains the recommended tire pressures for coldtires. The recommended tire pressures are validfor the maximum permissible load and up to themaximum permissible vehicle speed.

Tire pressure tableThe tire pressure table is on the inside of the fuelfiller flap. It shows the tire pressure for all tirespermitted at the factory for this vehicle; seeillustration (example).

The tire pressure table contains the recommen-ded pressures for cold tires for various operat-ing conditions, i.e. differing load and speed con-ditions.If a tire size precedes a tire pressure, the fol-lowing tire pressure information is only valid forthat tire size; see illustration (example).

The load conditions "partially laden" and "fullyladen" are defined in the table for different num-bers of occupants and amounts of luggage. Theactual number of seats may differ.

Some tire pressure tables show only the rimdiameters instead of the full tire size, e.g. R18.Rim diameter is part of the tire size and can befound on the tire sidewall (Y page 296).If the tire pressures have been set to the lowervalues for lighter loads and/or lower roadspeeds, the pressures should be reset to thehigher values:Rif you want to drive with an increased loadand/orRif you want to drive at higher speeds

i The tire pressures for increased loads and/or higher road speeds, shown in the tire pres-sure table, may have a negative effect on driv-ing comfort.

If the tire pressure is not set correctly, this canlead to an excessive build up of heat and a sud-den loss of pressure.For more information, contact a qualified spe-cialist workshop.

Important notes on tire pressure

G WARNINGIf the tire pressure drops repeatedly, thewheel, valve or tire may be damaged. Tirepressure that is too low may result in a tireblow-out. There is a risk of an accident.RCheck the tire for foreign objects.RCheck whether the wheel is losing air or thevalve is leaking.

If you are unable to rectify the damage, con-tact a qualified specialist workshop.

G WARNINGIf you fit unsuitable accessories onto tirevalves, the tire valves may be overloaded andmalfunction, which can cause tire pressureloss. Due to their design, retrofitted tire pres-sure monitors keep the tire valve open. Thiscan also result in tire pressure loss. There is arisk of an accident.Only screw the standard valve cap or othervalve caps approved by Mercedes-Benz foryour vehicle onto the tire valve.

Use a suitable pressure gauge to check the tirepressure. The outer appearance of a tire doesnot permit any reliable conclusion about the tirepressure. On vehicles equipped with the elec-tronic tire pressure monitor, the tire pressurecan be checked in the on-board computer.The tire temperature and pressure increasewhen the vehicle is in motion. This is dependenton the driving speed and the load.Therefore, you should only correct tire pres-sures when the tires are cold.The tires are cold:Rif the vehicle has been parked with the tiresout of direct sunlight for at least three hoursandRif the vehicle has been driven less than 1 mile(1.6 km)

The tire temperature changes depending on theoutside temperature, the vehicle speed and thetire load. If the tire temperature changes by18 ‡ (10 †), the tire pressure changes byapproximately 10 kPa (0.1 bar/1.5 psi). Takethis into account when checking the pressure ofwarm tires. Only correct the tire pressure if it is

too low for the current operating conditions. Ifyou check the tire pressure when the tires arewarm, the resulting value will be higher than ifthe tires were cold. This is normal. Do notreduce the tire pressure to the value specifiedfor cold tires. The tire pressure would otherwisebe too low.Observe the recommended tire pressures forcold tires:Ron the Tire and Loading Information placardon the B-pillar on the driver's sideRin the tire pressure table in the fuel filler flap(Y page 138)

Underinflated or overinflated tires

Underinflated tires

G WARNINGTires with pressure that is too low can over-heat and burst as a consequence. In addition,they also suffer from excessive and/or irreg-ular wear, which can severely impair the brak-ing properties and the driving characteristics.There is a risk of an accident.Avoid tire pressures that are too low in all thetires, including the spare wheel.

Underinflated tires may:Roverheat, leading to tire defectsRadversely affect handlingRwear excessively and/or unevenlyRhave an adverse effect on fuel consumption

Overinflated tires

G WARNINGTires with excessively high pressure can burstbecause they are damaged more easily byroad debris, potholes etc. In addition, theyalso suffer from irregular wear, which canseverely impair the braking properties and thedriving characteristics. There is a risk of anaccident.Avoid tire pressures that are too high in all thetires, including the spare wheel.

X Press the tire pressure gauge securely ontothe valve.

X Read the tire pressure and compare it to therecommended value on the Tire and LoadingInformation placard or the tire pressure table(Y page 285).

X If the tire pressure is too low, increase the tirepressure to the recommended value.

X If the tire pressure is too high, release air. Todo so, press down the metal pin in the valve,using the tip of a pen for example. Then checkthe tire pressure again using the tire pressurechecker.

X Screw the valve cap onto the valve.X Repeat these steps for the other tires.

Tire pressure loss warning system(Canada only)

General notesWhile the vehicle is in motion, the tire pressureloss warning system monitors the set tire pres-sure using the rotational speed of the wheels.This enables the system to detect significantpressure loss in a tire. If the speed of rotation ofa wheel changes as a result of a loss of pressure,a corresponding warningmessage will appear inthe multifunction display.You can recognize the tire pressure losswarningby the Run Flat Indicator Active Press'OK' to Restartmessage in themultifunctiondisplay in the Serv. menu.

Important safety notes

G WARNINGEach tire, including the spare (if provided),should be checked at least once every twoweeks when cold and inflated to the pressurerecommended by the vehicle manufactureron the Tire and Loading Information placardon the driver's door B-pillar or the tire pres-sure label on the inside of the fuel filler flap. Ifyour vehicle has tires of a different size thanthe size indicated on the Tire and LoadingInformation placard or, if available, the tirepressure label, you should determine theproper tire pressure for those tires.As an added safety feature, your vehicle hasbeen equippedwith a tire pressuremonitoringsystem (TPMS) that illuminates a low tire pres-sure telltale when one or more of your tiresare significantly underinflated. Accordingly,when the low tire pressure telltale lights up,you should stop and check your tires as soonas possible, and inflate them to the properpressure. Driving on a significantly underin-flated tire causes the tire to overheat and canlead to tire failure.Underinflation also reduces fuel efficiencyand tire tread life, andmay affect the vehicle'shandling and stopping ability. Please note thatthe TPMS is not a substitute for proper tiremaintenance, and it is the driver's responsi-bility to maintain correct tire pressure, even ifunderinflation has not reached the level totrigger illumination of the TPMS low tire pres-sure telltale.Your vehicle has also been equipped with aTPMS malfunction indicator to indicate whenthe system is not operating properly. TheTPMS malfunction indicator is combined withthe low tire pressure telltale. When the sys-tem detects a malfunction, the warning lampwill flash for approximately a minute and thenremain continuously illuminated. Thissequencewill be repeated every time the vehi-cle is started as long as the malfunctionexists. When the malfunction indicator is illu-

minated, the systemmay not be able to detector signal low tire pressure as intended.TPMS malfunctions may occur for a variety ofreasons, including the installation of incom-patible replacement or alternate tires orwheels on the vehicle that prevent the TPMSfrom functioning properly. Always check theTPMS malfunction telltale after replacing oneor more tires or wheels on your vehicle toensure that the replacement or alternate Tiresand wheels allow the TPMS to continue tofunction properly.

It is the driver's responsibility to set the tirepressure to that recommended for cold tireswhich is suitable for the operating situation(Y page 285). Note that the correct tire pressurefor the current operating situation must first betaught-in to the tire pressure monitor. If a sub-stantial loss of pressure occurs, the warningthreshold for the warning message is aligned tothe taught-in reference values. Restart the tirepressuremonitor after adjusting the pressure ofthe cold tires (Y page 291). The current pres-sures are saved as new reference values. As aresult, a warning message will appear if the tirepressure drops significantly.The tire pressure monitor does not warn you ofan incorrectly set tire pressure. Observe thenotes on the recommended tire pressure(Y page 285).The tire pressuremonitor is not able to warn youof a sudden loss of pressure, e.g. if the tire ispenetrated by a foreign object. In the event of asudden loss of pressure, bring the vehicle to ahalt by braking carefully. Avoid abrupt steeringmovements.The tire pressure monitor has a yellow warninglamp in the instrument cluster for indicatingpressure loss or a malfunction. Whether thewarning lamp flashes or lights up indicateswhether a tire pressure is too low or the tirepressure monitor is malfunctioning:Rif the warning lamp is lit continuously, the tirepressure on one or more tires is significantlytoo low. The tire pressure monitor is not mal-functioning.Rif the warning lamp flashes for around aminute and then remains lit constantly, thetire pressure monitor is malfunctioning.

In addition to the warning lamp, a messageappears in the multifunction display. Observe

Instruction labels for tires and loads

G WARNINGOverloaded tires can overheat, causing ablowout. Overloaded tires can also impair the

steering and driving characteristics and leadto brake failure. There is a risk of accident.Observe the load rating of the tires. The loadrating must be at least half of the GAWR ofyour vehicle. Never overload the tires byexceeding the maximum load.

Two instruction labels on your vehicle show themaximum possible load.(1) The Tire and Loading Information placard is

on the B-pillar on the driver's side. The Tireand Loading Information placard shows themaximum permissible number of occu-pants and themaximumpermissible vehicleload. It also contains details of the tire sizesand corresponding pressures for tiresmounted at the factory.

(2) The vehicle identification plate is on the B-pillar on the driver's side. The vehicle iden-tification plate informs you of the grossvehicle weight rating. It is made up of thevehicle weight, all vehicle occupants, thefuel and the cargo. You can also find infor-mation about the maximum gross axleweight rating on the front and rear axle.The maximum gross axle weight rating isthe maximum weight that can be carried byone axle (front or rear axle). Never exceedthe maximum load or the maximum grossaxle weight rating for the front or rear axle.

Determining the correct load limit

Step-by-step instructionsThe following steps have been developed asrequired of all manufacturers under Title 49,Code of U.S. Federal Regulations, Part 575 pur-suant to the "National Traffic and Motor VehicleSafety Act of 1966".X Step 1: Locate the statement "The combinedweight of occupants and cargo should neverexceed XXX kg or XXX lbs." on your vehicle’sTire and Loading Information placard.

X Step 2: Determine the combined weight ofthe driver and passengers that will be riding inyour vehicle.

X Step 3: Subtract the combined weight of thedriver and passengers from XXX kilograms orXXX lbs.

X Step 4: The resulting figure equals the avail-able amount of cargo and luggage load capa-city. For example, if the "XXX" amount equals1400 lbs and there will be five 150-lb pas-sengers in your vehicle, the amount of avail-able cargo and luggage load capacity is650 lbs (1400 - 750 (5 x 150) = 650 lbs).

X Step 5: Determine the combined weight ofluggage and cargo being loaded on the vehi-cle. That weight may not safely exceed theavailable cargo and luggage load capacity cal-culated in step 4.

Example: steps 1 to 3The following table shows examples on how to calculate total and cargo load capacities with varyingseating configurations and number and size of occupants. The following examples use a load limit of

Uniform Tire Quality Grading Stand-ards

Overview of Tire Quality Grading Stand-ards

Uniform Tire Quality Grading Standards are U.S.government specifications. Their purpose is toprovide drivers with uniform reliable informationon tire performance data. Tire manufacturershave to grade tires using three performance fac-tors:: tread wear grade,; traction grade and= temperature grade. These regulations do notapply to Canada. Nevertheless, all tires sold inNorth America are provided with the corre-sponding quality grading markings on the side-wall of the tire.Quality grades can be found, where applicable,on the tire sidewall between tread shoulder andmaximum section width.

Example:RTreadwear grade: 200RTraction grade: AARTemperature grade: AAll passenger car tiresmust conform to the stat-utory safety requirements in addition to thesegrades.

i The actual values for tires are vehicle-spe-cific and may deviate from the values in theillustration.

TreadwearThe treadwear grade is a comparative ratingbased on the wear rate of the tire when testedunder controlled conditions on a specified U.S.government course. For example, a tire graded150 would wear one and one-half times as wellon the government course as a tire graded 100.The relative performance of tires depends uponthe actual conditions of their use, however, andmay depart significantly from the norm due tovariations in driving habits, service practicesand differences in road characteristics and cli-mate.

Traction

G WARNINGThe traction grade assigned to this tire isbased on straight-ahead braking tractiontests, and does not include acceleration, cor-nering, hydroplaning, or peak traction char-acteristics.

! Avoid wheelspin. This can lead to damage tothe drive train.

The traction grades – from highest to lowest –are AA, A, B and C. Those grades represent thetire's ability to stop on wet pavement as meas-ured under controlled conditions on specifiedgovernment test surfaces of asphalt and con-crete. A tire marked C may have poor tractionperformance.The safe speed on a wet, snow covered or icyroad is always lower than on dry road surfaces.You should pay special attention to road condi-tions when temperatures are around freezingpoint.Mercedes-Benz recommends a minimum treaddepth ofã in (4 mm) on all four winter tires.

Observe the legally required minimum tire treaddepth (Y page 283). Winter tires can reduce thebraking distance on snow-covered surfaces incomparison with summer tires. The braking dis-tance is still much further than on surfaces thatare not icy or covered with snow. Take appro-priate care when driving.Further information on winter tires (M+S tires)(Y page 284).

Temperature

G WARNINGThe temperature grade for this tire is estab-lished for a tire that is properly inflated andnot overloaded. Excessive speed, underinfla-tion, or excessive loading, either separately orin combination, can cause excessive heatbuild-up and possible tire failure.

The temperature grades are A (the highest), B,and C, representing the tire's resistance to thegeneration of heat and its ability to dissipateheat when tested under controlled conditionson a specified indoor laboratory test wheel. Sus-tained high temperature can cause the materialof the tire to degenerate and reduce tire life, andexcessive temperature can lead to sudden tirefailure. The grade C corresponds to a level ofperformance which all passenger car tires mustmeet under the Federal Motor Vehicle SafetyStandard No. 109. Grades B and A representhigher levels of performance on the laboratorytest wheel than the minimum required by law.

Uniform Tire Quality Grading StandardsA uniform standard to grade the quality of tireswith regards to tread quality, tire traction andtemperature characteristics. The quality grad-ing assessment is made by the manufacturerfollowing specifications from the U.S. govern-ment. The ratings aremolded into the sidewall ofthe tire.

Recommended tire pressuresThe recommended tire pressure applies to thetires mounted at the factory.The Tire and Loading Information placard con-tains the recommended tire pressures for coldtires on a fully loaded vehicle and for the maxi-mum permissible vehicle speed.The tire pressure table contains the recommen-ded pressures for cold tires for various operat-ing conditions, i.e. differing load and speed con-ditions.

Increased vehicle weight due to optionalequipmentThe combined weight of all standard andoptional equipment available for the vehicle,regardless of whether it is actually installed onthe vehicle or not.

RimThis is the part of the wheel on which the tire ismounted.

GAWR (Gross Axle Weight Rating)The GAWR is the maximum gross axle weightrating. The actual load on an axle must neverexceed the gross axle weight rating. The grossaxle weight rating can be found on the vehicleidentification plate on the B-pillar on the driver'sside.

Speed ratingThe speed rating is part of the tire identification.It specifies the speed range for which the tire isapproved.

GVW (Gross Vehicle Weight)The gross vehicle weight includes the weight ofthe vehicle including fuel, tools, the sparewheel,accessories installed, occupants, luggage andthe drawbar noseweight, if applicable. The grossvehicle weight must not exceed the gross vehi-cle weight rating GVWR as specified on the vehi-cle identification plate on the B-pillar on thedriver's side.

GVWR (Gross Vehicle Weight Rating)The GVWR is the maximum permissible grossweight of a fully loaded vehicle (theweight of thevehicle including all accessories, occupants,fuel, luggage and the drawbar noseweight, ifapplicable). The gross vehicle weight rating isspecified on the vehicle identification plate onthe B-pillar on the driver's side.

Maximum loaded vehicle weightThe maximum weight is the sum of:Rthe curb weight of the vehicleRthe weight of the accessoriesRthe load limitRthe weight of the factory installed optionalequipment

Kilopascal (kPa)Metric unit for tire pressure. 6.9 kPa corre-sponds to 1 psi. Another unit for tire pressure isbar. 100 kilopascals (kPa) are the equivalent of1 bar.

Load indexIn addition to the load-bearing index, the loadindex may also be imprinted on the sidewall ofthe tire. This specifies the load-bearing capacitymore precisely.

Curb weightTheweight of a vehicle with standard equipmentincluding the maximum capacity of fuel, oil andcoolant. It also includes the air-conditioning sys-tem and optional equipment if these are instal-led in the vehicle, but does not include passen-gers or luggage.

Maximum load ratingThe maximum tire load is the maximum permis-sible weight in kilograms or lbs for which a tire isapproved.

Maximum permissible tire pressureMaximum permissible tire pressure for one tire.

Maximum load on one tireMaximum load on one tire. This is calculated bydividing the maximum axle load of one axle bytwo.

PSI (pounds per square inch)A standard unit of measure for tire pressure.

Aspect ratioRelationship between tire height and tire widthin percent.

Tire pressureThis is pressure inside the tire applying an out-ward force to each square inch of the tire's sur-face. The tire pressure is specified in pounds persquare inch (psi), in kilopascal (kPa) or in bar.The tire pressure should only be corrected whenthe tires are cold.

Cold tire pressureThe tires are cold:Rif the vehicle has been parked with the tiresout of direct sunlight for at least three hoursandRif the vehicle has not been driven further than1 mile (1.6 km)

TreadThe part of the tire that comes into contact withthe road.

BeadThe tire bead ensures that the tire sits securelyon thewheel. There are several steel wires in thebead to prevent the tire from coming loose fromthe wheel rim.

SidewallThe part of the tire between the tread and thebead.

Weight of optional extrasThe combined weight of those optional extrasthat weigh more than the replaced standardparts and more than 2.3 kg (5 lbs). Theseoptional extras, such as high-performancebrakes, level control, a roof rack or a high-per-formance battery, are not included in the curbweight and the weight of the accessories.

TIN (Tire Identification Number)This is a unique identifier which can be used bya tire manufacturer to identify tires, for examplefor a product recall, and thus identify the pur-chasers. The TIN is made up of the manufactur-er's identity code, tire size, tire type code andthe manufacturing date.

Load bearing indexThe load bearing index (also load index) is a codethat contains the maximum load bearing capa-city of a tire.

TractionTraction is the result of friction between the tiresand the road surface.

Treadwear indicatorsNarrow bars (tread wear bars) that are distrib-uted over the tire tread. If the tire tread is levelwith the bars, the wear limit ofá in (1.6 mm)has been reached.

Occupant distributionThe distribution of occupants in a vehicle at theirdesignated seating positions.

Total load limitNominal load and luggage load plus 68 kg(150 lbs) multiplied by the number of seats inthe vehicle.

Changing a wheel

Flat tireThe "Breakdown assistance" section(Y page 266) contains information and notes onhow to deal with a flat tire. Information on driv-ing with MOExtended tires in the event of a flattire can be found under "MOExtended tires (tireswith run-flat characteristics" (Y page 267).

Rotating the wheels

G WARNINGInterchanging the front and rear wheels mayseverely impair the driving characteristics ifthe wheels or tires have different dimensions.The wheel brakes or suspension componentsmay also be damaged. There is a risk of acci-dent.Rotate front and rearwheels only if thewheelsand tires are of the same dimensions.

! On vehicles equipped with a tire pressuremonitor, electronic components are locatedin the wheel.

Tire-mounting tools should not be used nearthe valve. This could damage the electroniccomponents.Only have tires changed at a qualified spe-cialist workshop.

Observe the instructions and safety notes in the"Changing a wheel" section (Y page 301).The wear patterns on the front and rear tiresdiffer, depending on the operating conditions.Rotate the wheels before a clear wear patternhas formed on the tires. Front tires typicallywear more on the shoulders and the rear tires inthe center.On vehicles that have the same size front andrear wheels, you can rotate the wheels accord-ing to the intervals in the tire manufacturer'swarranty book in your vehicle documents. If nowarranty book is available, the tires should berotated every 3,000 to 6,000 miles (5,000 to10,000 km). Depending on tire wear, this maybe required earlier. Do not change the directionof wheel rotation.Clean the contact surfaces of the wheel and thebrake disc thoroughly every time awheel is rota-ted. Check the tire pressure and, if necessary,restart the tire pressure loss warning system(Canada only) or the tire pressure monitor (USAonly).

Direction of rotationTires with a specified direction of rotation haveadditional benefits, e.g. if there is a risk of hydro-planing. These advantages can only be gained ifthe tires are installed corresponding to thedirection of rotation.An arrow on the sidewall of the tire indicates itscorrect direction of rotation.

Storing wheelsStore wheels that are not being used in a cool,dry and preferably dark place. Protect the tiresfrom oil, grease, gasoline and diesel.

Wheel and tire combinations

General notesYou can ask for information regarding permittedwheel/tire combinations at an authorizedMercedes-Benz Center.You should regularly check the pressure of theemergency spare wheel, particularly prior tolong trips, and correct the pressure as neces-sary (Y page 285). The value on the wheel isvalid.

! For safety reasons, Mercedes-Benz recom-mends that you only use tires and wheelswhich have been approved byMercedes-Benzspecifically for your vehicle.These tires have been specially adapted foruse with the control systems, such as ABS orESP®, and are marked as follows:RMO = Mercedes-Benz OriginalRMOE = Mercedes-Benz Original Extended(tires featuring run-flat characteristics)RMO1 = Mercedes-Benz Original (only cer-tain AMG tires)

Mercedes-Benz Original Extended tires mayonly be used on wheels that have been spe-cifically approved by Mercedes-Benz.Only use tires, wheels or accessories testedand approved by Mercedes-Benz. Certaincharacteristics, e.g. handling, vehicle noiseemissions or fuel consumption, may other-wise be adversely affected. In addition, whendriving with a load, tire dimension variationscould cause the tires to come into contactwith the bodywork and axle components. Thiscould result in damage to the tires or the vehi-cle.Mercedes-Benz accepts no liability for dam-age resulting from the use of tires, wheels oraccessories other than those tested andapproved.Information on tires, wheels and approvedcombinations can be obtained from any quali-fied specialist workshop.

! Retreaded tires are neither tested nor rec-ommended by Mercedes-Benz, since previ-ous damage cannot always be detected onretreaded tires. As a result, Mercedes-Benzcannot guarantee vehicle safety if retreadedtires are mounted. Do not mount used tires ifyou have no information about their previoususage.

The recommended pressures for various oper-ating conditions can be found:Ron the Tire and Loading Information placardon the B-pillar on the driver's sideRin the tire pressure table in the fuel filler flapObserve the notes on recommended tire pres-sures under various operating conditions(Y page 285).Check tire pressures regularly, and only whenthe tires are cold. Comply with the maintenancerecommendations of the tire manufacturer inthe vehicle document wallet.Notes on the vehicle equipment – always equipthe vehicle:Rwith tires of the same size on a given axle (leftand right)Rwith the same type of tire (summer tires,MOExtended tires, winter tires)Exception: it is permissible to install a differ-ent type or make in the event of a flat tire.Observe the "MOExtended tires (tires withrun-flat characteristics" section (Y page 267).

Vehicles equipped with MOExtended tires arenot equipped with a TIREFIT kit at the factory. Itis therefore recommended that you additionallyequip your vehiclewith a TIREFIT kit if youmounttires that do not feature run-flat properties, e.g.winter tires. A TIREFIT kit may be obtained froma qualified specialist workshop.
