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 traction control lightilluminates 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 tractioncontrol 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 111).
Using a Switch (If Equipped)
Use the traction control switch on theinstrument panel to switch the system off oron.

PRINCIPLE OF OPERATION
WARNINGS
Vehicle modifications involving brakingsystem, aftermarket roof racks,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.
WARNINGS
Remember that even advancedtechnology cannot defy the laws ofphysics. 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:

Stability Control

Electronic Stability Control
The system enhances your vehicle’s abilityto prevent skids or lateral slides by applyingbrakes to one or more of the wheelsindividually and, if necessary, reducingengine power.
Traction Control
The system enhances your vehicle’s abilityto maintain traction of the wheels bydetecting and controlling wheel spin. SeeUsing Traction Control (page 201).
