HOW DOES TRACTION CONTROL
WORK
If your vehicle begins to slide, the systemapplies the brakes to individual wheels and,when needed, reduces power at the sametime. If the wheels spin when acceleratingon slippery or loose surfaces, the systemreduces power in order to increase traction.
SWITCHING TRACTION CONTROL
ON AND OFF
WARNING: Operating your vehiclewith the traction control disabled couldlead to an increased risk of loss of vehiclecontrol, vehicle rollover, personal injuryand death.
When you switch the system off or on, amessage appears in the information displayshowing system status.
You can switch the system off with thetraction control switch.
Using a Switch
Use the traction control switch on theinstrument panel to switch the system off oron.

HOW DOES STABILITY CONTROL
WORK
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 stabilitycontrol system. In addition, installing anystereo loudspeakers may interfere withand adversely affect the electronic stabilitycontrol system. Install any aftermarketstereo loudspeaker as far as possible fromthe front center console, the tunnel, andthe front seats in order to minimize the riskof interfering with the electronic stabilitycontrol sensors. Reducing theeffectiveness of the electronic stabilitycontrol system could lead to an increasedrisk of loss of vehicle control, vehiclerollover, personal injury and death.
WARNING: Remember that evenadvanced technology cannot defy the lawsof physics. It's always possible to losecontrol of a vehicle due to inappropriatedriver input for the conditions. Aggressivedriving on any road condition can causeyou to lose control of your vehicleincreasing the risk of personal injury orproperty damage. Activation of theelectronic stability control system is anindication that at least some of the tireshave exceeded their ability to grip theroad; this could reduce the operator'sability to control the vehicle potentiallyresulting in a loss of vehicle control, vehiclerollover, personal injury and death. If yourelectronic stability control system activates,SLOW DOWN.
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.
The stability control system has severalfeatures built into it to help you maintaincontrol of your vehicle:
Electronic Stability Control
Electronic stability control enhances yourvehicle’s ability to prevent skids or lateralslides by applying brakes to one or more ofthe wheels individually and, if necessary,reducing engine power.
Roll Stability Control
Roll stability control enhances your vehicle’sability to prevent rollovers by detecting yourvehicle’s roll motion and the rate at which itchanges by applying the brakes to one ormore wheels individually.

Curve Control
Curve control enhances your vehicle’s abilityto follow the road when cornering severelyor avoiding objects in the roadway. Curvecontrol operates by reducing engine powerand, if necessary, applying brakes to one ormore of the wheels individually.
Traction Control
Traction control enhances your vehicle’sability to maintain traction of the wheels bydetecting and controlling wheel spin. SeeHow Does Traction Control Work (page 232).

SWITCHING STABILITY CONTROL
ON AND OFF
The system turns on each time you switchthe ignition on.
You can switch the electronic stability controlsystem off by pressing and holding the ESCoff button for over 15 seconds, or you canpress the button again to switch the systemon.
Shifting the transmission intoreverse (R) disables the system.
You can switch the traction control systemoff or on independently. See SwitchingTraction Control On and Off (page 232).
STABILITY CONTROL INDICATOR
If it does not illuminate when youswitch the power on, or remainson, this indicates a malfunction. Have your vehicle checked by an authorizeddealer as soon as possible.

PARKING AID PRECAUTIONS
WARNING: To help avoid personalinjury, always use caution when in reverse(R) and when using the sensing system.
WARNING: The system may notdetect objects with surfaces that absorbreflection. Always drive with due care andattention. Failure to take care may resultin a crash.
WARNING: Traffic control systems,fluorescent lamps, inclement weather, airbrakes, external motors and fans mayaffect the correct operation of the sensingsystem. This may cause reducedperformance or false alerts.
WARNING: The system may notdetect small or moving objects, particularlythose close to the ground.
WARNING: The parking aid systemcan only assist you to detect objects whenyour vehicle is moving at parking speeds.To help avoid personal injury you musttake care when using the parking aidsystem.
WARNING: The system may notfunction if the sensor is blocked.
WARNING: In cold and severeweather conditions the system may notfunction. Rain, snow and spray can all limitsensor performance.
WARNING: If damage occurs in theimmediate area surrounding the sensor,have your vehicle checked as soon aspossible.
Note:If your vehicle sustains damageleaving the sensors misaligned, this willcause inaccurate measurements or falsealerts.
When you connect a trailer to your vehicle,the rear parking aid detects the trailer andprovides an alert. Disable the parking aidwhen you connect a trailer to prevent thealert.
Note:Connected trailers might be detectedby the vehicle and parking aid turns offautomatically in those instances.
Note:Certain add-on devices installedaround the bumper or fascia may createfalse alerts, for example, large trailer hitches,bike or surfboard racks, license platebrackets, bumper covers or any other devicethat could block the normal detection zoneof the parking aid system. Aftermarket sparetires or spare tire covers mounted to the reartailgate could cause false alerts from thepark aid system. Remove the add-on deviceto prevent false alerts.
Note: Keep the sensors free from snow, iceand large accumulations of dirt. If thesensors are covered, the system's accuracycan be affected.
Do not clean the sensors with sharp objects.

FRONT PARKING AID AUDIBLEWARNINGS
A warning tone sounds when there is anobject within 28 in (70 cm) from the frontbumper. As your vehicle moves closer to anobject, the rate of the tone increases.
The warning tone continuously sounds whenan object is 12 in (30 cm) or less from thefront bumper.
Note:If the detected object is 12 in (30 cm)or less from your vehicle, visual indicationremains on.
SIDE PARKING AID
WHAT IS THE SIDE PARKING AID
The front and rear outermost parking aidsensors map objects that are near to thesides of your vehicle.
SIDE PARKING AID LIMITATIONS
The sensor coverage is up to 24 in (60 cm)from the sides of your vehicle.
The side parking aid may not function if:
•Your vehicle remains stationary for overtwo minutes.
•The anti-lock brake system activates.
•The traction control system activates.
•Your vehicle is in park (P).
•The steering wheel angle information isnot available. You must drive at least492 ft (150 m) above 19 mph (30 km/h) toreset the steering wheel angleinformation.
Note:If you switch traction control off, theside sensing system also turns off.
To reinitialize the system, drive the length ofyour vehicle.
The side parking aid does not detect anobject that is moving toward the side of yourvehicle, for example another vehicle movingat a low speed, if it does not pass a front orrear parking aid sensor.
If the transmission is in reverse (R), the sidesensing system provides audible warnings.When your vehicle is moving slowly,obstacles are detected within 24 in (60 cm)and are inside the driving path of yourvehicle. If your vehicle remains stationary fora few seconds, the audible warning turns off.Visual indication is always present in reverse(R).
If your vehicle is in neutral (N), the sidesensing system provides visual indicationonly when your vehicle is moving slowly andthere is a front or rear parking aid obstacledetected, and the side obstacle is within24 in (60 cm) from the side of your vehicle.If your vehicle remains stationary for a fewseconds, the visual indication turns off.
If the transmission is in drive (D) or any otherforward gear, the side sensing systemprovides audible and visual warnings. Whenyour vehicle is moving slowly, obstacles aredetected within 24 in (60 cm) and are insidethe driving path of your vehicle. If yourvehicle remains stationary for a few seconds,the visual indication and audible warningturns off.
