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. Have thesystem checked by an authorized dealer. Ifthe vehicle has continuous vibration orshudder in the steering wheel while braking,have it checked by an authorized dealer.
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 321).
See Warning Lamps andIndicators (page 104).
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. Movethe transmission to park (P), switch theengine off and apply the parking brake. Inspect the accelerator pedal for anyinterference. If none are found and thecondition persists, have your vehicle towedto the nearest authorized dealer.
Brake Assist
Brake assist detects when you rapidly brakeby measuring the rate at which you press thebrake pedal. It provides maximum brakingefficiency as long as you press the pedal.Brake assist can reduce stopping distancesin critical situations.
Anti-lock Brake System
This system helps you maintain steeringcontrol during emergency stops by keepingthe brakes from locking.
This lamp momentarily illuminateswhen you switch the ignition on. Ifthe light does not illuminate duringstart up, remains on or flashes, the anti-lockbraking system may be disabled. Have thesystem checked by an authorized dealer. Ifthe anti-lock brake system is disabled,normal braking is still effective.
If the brake warning lampilluminates when you release theparking brake, have your systemchecked by an authorized dealer. It alsoilluminates momentarily when you switch theignition on to confirm the lamp is functional.If it does not illuminate when you switch theignition on or begins to flash at any time,have the system checked by an authorizeddealer.
Note:The brake warning lamp mayilluminate and stay illuminated until youswitch off your vehicle as a result of drivingat high elevation.

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 the systemdetects a failure. Make sure you did notmanually disable the traction control systemusing the information display controls or theswitch. If the stability control and traction
control light is still illuminating steadily, havethe system serviced by an authorized dealerimmediately. Operating your vehicle with thetraction control disabled could lead to anincreased 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 Off
When you switch the system off or on, amessage appears in the information displayshowing system status.
You can switch the system off by either usingthe information display controls or the switch.
Using the Information Display Controls
You can switch this feature off or on in theinformation display. See General Information(page 110).
Using a Switch (If Equipped)
Use the traction control switch on theinstrument panel to switch the system off oron.

PRINCIPLE OF OPERATION
WARNING: Vehicle modificationsinvolving braking system, aftermarket roofracks, suspension, steering system, tireconstruction and wheel and tire size maychange the handling characteristics of yourvehicle and may adversely affect theperformance of the electronic stability controlsystem. In addition, installing any stereoloudspeakers may interfere with andadversely affect the electronic stabilitycontrol system. Install any aftermarket stereoloudspeaker as far as possible from the frontcenter console, the tunnel, and the frontseats in order to minimize the risk ofinterfering with the electronic stability controlsensors. Reducing the effectiveness of theelectronic stability control system could leadto an increased risk of loss of vehicle control,vehicle rollover, personal injury and death.
WARNING: Remember that evenadvanced technology cannot defy the lawsof physics. It’s always possible to lose controlof a vehicle due to inappropriate driver inputfor the conditions. Aggressive driving on anyroad condition can cause you to lose controlof your vehicle increasing the risk of personalinjury or property damage. Activation of theelectronic stability control system is anindication that at least some of the tires haveexceeded their ability to grip the road; thiscould reduce the operator’s ability to controlthe vehicle potentially resulting in a loss ofvehicle control, vehicle rollover, personalinjury and death. If your electronic stabilitycontrol system activates, SLOW DOWN.
The system automatically turns on each timeyou switch the ignition on.
If a fault occurs in either the stability controlor the traction control system, you mayexperience the following conditions:
•The stability and traction control lightilluminates steadily.
•The stability control and traction controlsystems do not enhance your vehicle'sability to maintain traction of the wheels.
If a driving condition activates either thestability control or the traction control systemyou may experience the following conditions:
•The stability and traction control lightflashes.
•Your vehicle slows down.
•Reduced engine power.
•A vibration in the brake pedal.
•The brake pedal is stiffer than usual.
•If the driving condition is severe and yourfoot is not on the brake, the brake pedalmay move as the system applies higherbrake force.
The stability control system has severalfeatures built into it to help you maintaincontrol of your vehicle:

PRINCIPLE OF OPERATION
WARNING: To help avoid personalinjury, always use caution when in reverse(R) and when using the sensing system.
WARNING: The system may not detectobjects with surfaces that absorb reflection.Always drive with due care and attention.Failure to take care may result in a crash.
WARNING: Traffic control systems,inclement weather, air brakes, externalmotors and fans may affect the correctoperation of the sensing system.This maycause reduced performance or false alerts.
WARNING: The system may not detectsmall or moving objects, particularly thoseclose to the ground.
Note:If your vehicle is equipped withMyKey™, the sensing system cannot beturned off when a MyKey™ is present. SeePrinciple of Operation (page 62).
Note:Keep the sensors, located on thebumper or fascia, free from snow, ice andlarge accumulations of dirt. If the sensorsare covered, the system’s accuracy can beaffected. Do not clean the sensors with sharpobjects.
Note:If your vehicle sustains damage to thebumper or fascia, leaving it misaligned orbent, the sensing zone may be alteredcausing inaccurate measurement ofobstacles or false alerts.
Note:Certain add-on devices installedaround the bumper or fascia may createfalse alerts. For example, large trailerhitches, bike or surfboard racks, license platebrackets, bumper covers or any other devicethat may block the normal detection zoneof the system. Remove the add-on device toprevent false alerts.
Note:When a trailer is connected to yourvehicle, the rear parking aid may detect thetrailer and therefore provide an alert. Disablethe rear parking aid when a trailer isconnected to prevent the alert.
The sensing system warns the driver ofobstacles within a certain range of yourvehicle. The system turns on automaticallywhenever you switch the ignition on.
The system can be switched off through theinformation display menu or from the pop-upmessage that appears once you shift thetransmission into reverse (R). See GeneralInformation (page 110).
If a fault is present in the system, a warningmessage appears in the information display.See Information Messages (page 121).
REAR PARKING AID
The rear sensors are only active when thetransmission is in reverse (R). As your vehiclemoves closer to the obstacle, the rate of theaudible warning increases. When theobstacle is less than 12 in (30 cm) away, thewarning sounds continuously. If the systemdetects a stationary or receding objectfarther than 12 in (30 cm) from the corners ofthe bumper, the tone sounds for only threeseconds. Once the system detects an objectapproaching, the warning sounds again.
