GENERAL INFORMATION
Note: Occasional brake noise is normal. Ifa metal-to-metal, continuous grinding orcontinuous squeal sound is present, thebrake linings may be worn-out and anauthorized dealer should check them. If thevehicle has continuous vibration or shudderin the steering wheel while braking, anauthorized dealer should check your vehicle.
Note:Brake dust may accumulate on thewheels, even under normal drivingconditions. Some dust is inevitable as thebrakes wear and does not contribute tobrake noise. See Cleaning the Wheels(page 385).
See Warning Lamps andIndicators (page 114).
Wet brakes result in reduced brakingefficiency. Gently press the brake pedal afew times when driving from a car wash orstanding water to dry the brakes.
Brake Over Accelerator
In the event the accelerator pedal becomesstuck or entrapped, apply steady and firmpressure to the brake pedal to slow thevehicle and reduce engine power. If youexperience this condition, apply the brakesand bring your vehicle to a safe stop. Switchthe engine off, move the transmission to park(P) and apply the parking brake. Inspect theaccelerator pedal and the area around it forany items or debris that may be obstructingits movement.If none are found and thecondition persists, have your vehicle towedto the nearest authorized dealer.
Emergency Brake Assist

PRINCIPLE OF OPERATION
The traction control system helps avoid drivewheel spin and loss of traction.
If your vehicle begins to slide, the systemapplies the brakes to individual wheels and,when needed, reduces engine power at thesame time. If the wheels spin whenaccelerating on slippery or loose surfaces,the system reduces engine power in orderto increase traction.
USING TRACTION CONTROL
WARNING: The stability and tractioncontrol light illuminates steadily if thesystem detects a failure. Make sure youdid not manually disable the tractioncontrol system using the informationdisplay controls or the switch. If the stabilitycontrol and traction control light is still
illuminating steadily, have the systemserviced by an authorized dealerimmediately. Operating your vehicle withthe traction control disabled could lead toan increased risk of loss of vehicle control,vehicle rollover, personal injury and death.
The system automatically turns on each timeyou switch the ignition on.
If your vehicle is stuck in mud or snow,switching traction control off may bebeneficial as this allows the wheels to spin.
Note:When you switch traction control off,stability control remains fully active.
Switching the System On and Off
You can switch traction control on and offthrough the information display controls. SeeGeneral Information (page 120).
When you switch the system off, a messageand an illuminated icon appear on theinstrument cluster.
Switch traction control on again to return thesystem to normal operations.
Note:Your vehicle may have MyKeyrestrictions regarding this feature. SeePrinciple of Operation (page 67).

Stop your vehicle assoon as it is safe to do so. Switch theignition off. After at least 10 seconds,switch the ignition on and watch theinformation display for a steering systemwarning message. If a steering systemwarning message returns, have the systemchecked by an authorized dealer.
WARNING: If the system detects anerror, you may not feel a difference in thesteering, however a serious condition mayexist. Obtain immediate service from anauthorized dealer, failure to do so mayresult in loss of steering control.
Your vehicle has an electric power steeringsystem. There is no fluid reservoir. Nomaintenance is required.
If your vehicle loses electrical power whileyou are driving, electric power steeringassistance is lost. The steering system stilloperates and you can steer your vehiclemanually. Manually steering your vehiclerequires more effort.
Extreme continuous steering may increasethe effort required for you to steer yourvehicle. This increased effort preventsoverheating and permanent damage to thesteering system. You do not lose the abilityto steer your vehicle manually. Typicalsteering and driving maneuvers allow thesystem to cool and return to normaloperation.
Steering Tips
If the steering wanders or pulls, check for:
•Correct tire pressures.
•Uneven tire wear.
•Loose or worn suspension components.
•Loose or worn steering components.
•Improper vehicle alignment.

Driving Aids

The system is not available:
•The system relies on many sub-systemsin your vehicle to operate correctly. Ifthose sub-systems are not operatingcorrectly the system may not beavailable.
•Low battery voltage is a condition whichwill prevent the system from operating.Please make sure the battery is correctlycharged if the system is not available.
•You may need to drive your vehiclestraight forward above 25 mph (40 km/h)before the system is available again.
•If the message still displays take yourvehicle to an authorized dealer forservice.
Sticker lost:
•If the system cannot initially find thesticker, it may be necessary for you tochange the lighting conditions by movingthe vehicle and trailer or waiting untilconditions change.
•Check for the following if you receive thelost sticker message while using thesystem.
•Stop your vehicle as soon as themessage displays.
•Make sure the sticker is visible and thepattern is discernable in the rear viewcamera image.
•Clean the sticker and camera to makesure they are unobstructed.
•Clean the lens with a soft, lint-free clothand water.
•Clean the sticker with isopropyl rubbingalcohol sprayed directly onto the sticker,and then wipe clean with a soft cloth.
•Remove any items that may be blockingthe view of the sticker. Depending onyour trailer configuration and anyequipment mounted to your trailer it ispossible for the sticker to be blockedfrom view of the camera as it rotates onthe hitch ball but not be blocked duringsetup. Remove the obstruction ifpossible. It will be necessary to removethe sticker from it’s current location if theobstruction cannot be cleared and placea new sticker that will be visible to thecamera in all positions of the trailerbehind your vehicle.
•Placing the sticker on a surface angledaway from the vehicle reducesperformance. Use a drawbar thatpositions the trailer level to the groundwhen attached to vehicle. This typicallyprovides a level surface to mount thesticker. Place the sticker on a bracket orother object when no level surface isavailable.
•Make sure the entire sticker is on a flatsurface that is completely visible to thecamera. Do not fold the sticker over anedge on the trailer frame. This candegrade performance.
•Shadows on the sticker may effecttracking performance under somelighting conditions. Moving the sticker toanother location within the allowedplacement area may improveperformance. Use the change stickeroption in your Towing menu if you movethe sticker.
