Brakes

When the system is active, your vehicle willremain stationary on the slope for two tothree seconds after you release the brakepedal. This allows you time to move yourfoot from the brake to the accelerator pedal. The brakes release automatically when theengine has sufficient torque to prevent yourvehicle from rolling down the grade. This isan advantage when pulling away on a slope,for example from a car park ramp, trafficlights or when reversing uphill into a parkingspace.
The system will activate automatically on anyslope that will cause significant vehiclerollback. For vehicles with a manualtransmission, you can switch this feature offusing the information display. SeeInformation Displays (page 119). The systemwill remain on or off depending on how itwas last set.
Note:There is no warning lamp to indicatethe system is either on or off.
Note:If your vehicle is equipped with AutoHold, Hill Start Assist will not be availablewhile Auto Hold is active.
Using Hill Start Assist
1. Bring your vehicle to a completestandstill. Keep the brake pedal pressedand select an uphill gear (for example,drive (D) or first (1) when facing uphill orreverse (R) when facing downhill).
2. If the sensors detect that your vehicle ison a slope, the system will activateautomatically.
3. When you remove your foot from thebrake pedal, your vehicle will remain onthe slope without rolling away for abouttwo or three seconds. This hold time willautomatically be extended if you are inthe process of driving off.
4. Drive off in the normal manner. Thebrakes will release automatically.
Switching the System On and Off
You can switch this feature on or off if yourvehicle is equipped with a manualtransmission and an information display. SeeGeneral Information (page 119). The systemremembers the last setting when you startyour vehicle.
If your vehicle is not equipped with a manualtransmission and an information display, youcannot turn the system on or off. When youswitch the ignition on, the systemautomatically turns on.
AUTO HOLD
WARNING: The system does notreplace the parking brake. When you leaveyour vehicle, always apply the parkingbrake.
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.

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 119).
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 68).

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 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.
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: Hill descent controlcannot control descent in all surfaceconditions and circumstances, such as iceor extremely steep grades. Hill descentcontrol is a driver assist system and cannotsubstitute for good judgment by the driver.Failure to do so may result in loss ofvehicle control, crash or serious injury.
WARNING: Hill descent control doesnot provide hill hold at zero miles per hour(0 kilometers per hour). When stopped,you must apply the parking brake or placethe vehicle in P (Park), or it may roll away.
Hill descent control allows you to set andmaintain vehicle speed while descendingsteep grades in various surface conditions.
Hill descent control can maintain vehiclespeeds on downhill grades between 2 mph(3 km/h) and 12 mph (20 km/h). Above 20mph (32 km/h), the system remains armed,but you cannot use the system to set ormaintain the descent speed.
Hill descent control requires a cooling downinterval after a period of sustained use. Theamount of time that the feature can remainactive before cooling varies with conditions.The system provides a warning in themessage center and a tone sounds whenthe system is about to disengage for cooling.At this time, manually apply the brakes asneeded to maintain descent speed.
USING HILL DESCENT CONTROL
You can switch the hill descentcontrol on and off through theinformation display.
To increase descent speed, press theaccelerator pedal until you reach the desiredspeed. To decrease descent speed, pressthe brake pedal until you reach the desiredspeed.
Whether accelerating or decelerating, onceyou reach the desired descent speed,remove your feet from the pedals and hilldescent control maintains the chosen vehiclespeed.
Note:You may observe noise from the ABSpump motor during hill descent controloperation. This is a normal characteristic ofthe ABS and should be no reason forconcern.
Hill Descent Modes
•At speeds between 2 mph (3 km/h) and20 mph (32 km/h): Your vehicle maintainsthe speed you desire while in this mode.
•At speeds between 20 mph (32 km/h)and 40 mph (64 km/h): Your vehicle doesnot maintain the speed you desire andyou cannot set your descent speed.
•At speeds above 40 mph (64 km/h): Youneed to switch this feature back on touse.

If a fault is present in the system, a warningmessage appears in the information displayand does not allow you to switch the systemon. See Information Messages (page 124).
If a sensor is blocked and cannot function,the system becomes disabled and a warningmessage appears in the information display.The system returns to a normal state oncethe blockage is cleared.
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.
Coverage area of up to 6 ft (1.8 m) from therear bumper. There may be decreasedcoverage area at the outer corners of thebumper.
The system detects certain objects while thetransmission is in reverse (R) :
•Your vehicle is moving toward astationary object at a speed of 3 mph(5 km/h) or less.
•Your vehicle is not moving, but a movingobject is approaching the rear of yourvehicle at a speed of 3 mph (5 km/h) orless.
•Your vehicle is moving at a speed of lessthan 3 mph (5 km/h) and a moving objectis approaching the rear of your vehicleat a speed of less than 3 mph (5 km/h).
The system provides audio warnings onlywhen your vehicle is moving or when yourvehicle is stationary and the detectedobstacle is less than 12 in (30 cm) away fromthe bumper.
Obstacle Distance Indicator (If Equipped)
The system provides obstacle distanceindication through the information display.The distance indicator displays when thetransmission is in reverse (R).
