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:

Stability Control

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 116).
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.

Parking Aids

If the transmission is in neutral (N), the sidesensing system provides visual distanceindication only when your vehicle is movingbelow a speed of 5 mph (8 km/h) and thereis a front or rear parking aid obstacledetected, and the side obstacle is within24 in (60 cm) from the side of your vehicle.When you stop your vehicle the visualdistance indication stops after four seconds.
If the side sensing system is not available,the side distance indicator blocks do notappear.
The side sensing system is not availableunder the following condition:
•If you switch the traction control systemoff.
The side sensing system may not beavailable until you have driven approximatelythe length of your vehicle in order for thesystem to reinitialize if:
•You switch the ignition on, off and backon.
•Your vehicle remains stationary for overtwo minutes.
•The anti-lock brake system is activated.
•The traction control system is activated.
•When the steering wheel angleinformation is not available, the sidesensing system is not available. Thevehicle must be driven at least 492 ft(150 m) above 19 mph (30 km/h) torecover the steering wheel angleinformation.
ACTIVE PARK ASSIST (If Equipped)
WARNING: You must remain in yourvehicle when the system turns on. At alltimes, you are responsible for controllingyour vehicle, supervising the system andintervening, if required. Failure to take caremay result in the loss of control of yourvehicle, serious personal injury or death.
WARNING: The sensors may not detectobjects in heavy rain or other conditions thatcause interference.
WARNING: Active park assist does notapply the brakes under any circumstances.
WARNING: You are responsible forcontrolling your vehicle at all times. Thesystem is designed to be an aid and doesnot relieve you of your responsibility to drivewith due care and attention. Failure to followthis instruction could result in the loss ofcontrol of your vehicle, personal injury ordeath.
Note:Keep the sensors free from snow, iceand large accumulations of dirt.
Note:Do not cover up the sensors.
Note:Do not clean the sensors with sharpobjects.
Note:The sensors may not detect objectswith surfaces that absorb ultrasonic waves.The sensors may falsely detect objects dueto ultrasonic interference caused bymotorcycle exhausts, truck air brakes orhorns, for example.
Note:If you change any tires, the systemmust recalibrate and may not correctlyoperate for a short time.

Parking Aids

A vehicle graphic illuminates if there is avehicle detected in front of you.
Note:When adaptive cruise control is active,the speedometer may vary slightly from theset speed displayed in the informationdisplay.
Setting the Adaptive Cruise SpeedWhen Your Vehicle is Stationary
Follow a vehicle to a complete stop.
Press while keeping the brakepedal fully pressed.
The set speed adjusts to 20 mph (30 km/h).
The indicator, current gap setting and setspeed appear in the information display.
Following a Vehicle
WARNING: When following a vehicle,your vehicle does not always deceleratequickly enough to avoid a crash withoutdriver intervention. Always apply the brakeswhen necessary. Failing to do so may resultin a crash, serious injury or death.
WARNING: Adaptive cruise controlonly warns of vehicles detected by the radarsensor. In some cases there may be nowarning or a delayed warning. You shouldalways apply the brakes when necessary.Failure to do so may result in a crash, seriousinjury or death.
When a vehicle ahead of you enters thesame lane or a slower vehicle is ahead in thesame lane, the vehicle speed adjusts tomaintain a preset gap distance. A vehiclegraphic illuminates in the instrument cluster.
Note:The brakes may emit noise whenapplied by the system.
Note:When you are following a vehicle andyou switch on a direction indicator, adaptivecruise control may provide a small temporaryacceleration to help you pass.
Your vehicle maintains a consistent gap fromthe vehicle ahead until:
•The vehicle in front of you accelerates toa speed above the set speed.
•The vehicle in front of you moves out ofthe lane you are in.
•You set a new gap distance.
The system applies the brakes to slow yourvehicle to maintain a safe gap distance fromthe vehicle in front. The system only applieslimited braking. You can override the systemby applying the brakes.
If the system determines that its maximumbraking level is not sufficient, an audiblewarning sounds when the system continuesto brake. A red warning bar displays on thewindshield and you must take immediateaction.
Following a Vehicle to a Complete Stop
If your vehicle follows a vehicle to a completestop and remains stationary for less thanthree seconds, your vehicle accelerates froma stationary position to follow the vehicleahead.

Detection Issues
WARNING: On rare occasions,detection issues can occur due to the roadinfrastructures, for example bridges, tunnelsand safety barriers. In these cases, thesystem may brake late or unexpectedly. Atall times, you are responsible for controllingyour vehicle, supervising the system andintervening, if required.
WARNING: If the system malfunctions,have your vehicle checked as soon aspossible.
The radar sensor has a limited field of view.It may not detect vehicles at all or detect avehicle later than expected in somesituations. The lead vehicle graphic does notilluminate if the system does not detect avehicle in front of you.
Detection issues can occur:
When driving on a different linethan the vehicle in front.A
With vehicles that edge into yourlane. The system can only detectthese vehicles once they movefully into your lane.
B
There may be issues with thedetection of vehicles in front whendriving into and coming out of abend or curve in the road.
C
In these cases, the system may brake late orunexpectedly. You should stay alert and takeaction when necessary.
If something hits the front end of your vehicleor damage occurs, the radar-sensing zonemay change. This could cause missed orfalse vehicle detection.
Optimal system performance requires a clearview of the road by the windshield-mountedcamera.
Optimal performance may not occur if:
