Using Hill Start Assist
1. Bring your vehicle to a completestandstill. Keep the brake pedalpressed and select an uphill gear (forexample, first (1) when facing uphill orreverse (R) when facing downhill).
2. If the sensors detect that your vehicleis on a slope, the system will activateautomatically.
3. When you remove your foot from thebrake pedal, your vehicle will remainon the slope without rolling away forabout two or three seconds. This holdtime will automatically be extended ifyou are in the 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.See General Information (page 92). Thesystem remembers the last setting whenyou start your vehicle.
If your vehicle is not equipped with amanual transmission and an informationdisplay, you cannot turn the system on oroff. When you switch the ignition on, thesystem automatically turns on.

PRINCIPLE OF OPERATION
The traction control system helps avoiddrive wheel spin and loss of traction.
If your vehicle begins to slide, the systemapplies the brakes to individual wheelsand, when needed, reduces engine powerat the same 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 controllight illuminates steadily if thesystem detects a failure. Make sureyou did not manually disable the tractioncontrol system using the switch. If thestability control and traction control lightis still illuminating steadily, have thesystem serviced by an authorized dealerimmediately. Operating your vehicle withtraction control disabled could lead to anincreased risk of loss of vehicle control,vehicle rollover, personal injury and death.
The system automatically turns on eachtime you 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
The switch for the stability and tractioncontrol system is on the instrument panel.
When you switch the system off, amessage and an illuminated icon appearon the instrument cluster.
Use the switch again to return the tractioncontrol system to normal operation.
Your vehicle may have MyKey restrictionsregarding this feature. See Principle ofOperation (page 46).

PRINCIPLE OF OPERATION
WARNINGS
Vehicle modifications involvingbraking system, aftermarket roofracks, suspension, steering system,tire construction and wheel and tire sizemay change the handling characteristicsof your vehicle and may adversely affectthe performance 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.
Remember that even advancedtechnology cannot defy the laws ofphysics. 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 the road;this could reduce the operator’s ability tocontrol the vehicle potentially resulting ina loss of vehicle control, vehicle rollover,personal injury and death. If your electronicstability control system activates, SLOWDOWN.
The system automatically turns on eachtime you switch the ignition on.
If a driving condition activates either thestability control or the traction controlsystem you may experience the followingconditions:
•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 andyour foot is not on the brake, the brakepedal may move as the systemsapplies higher brake forces.
The stability control system has severalfeatures built into it to help you maintaincontrol of your vehicle:
Electronic Stability Control
The system enhances your vehicle’s abilityto prevent skids or lateral slides byapplying brakes to one or more of thewheels individually and, if necessary,reducing engine power.
Roll Stability Control
The system enhances your vehicle’s abilityto prevent rollovers by detecting yourvehicle’s roll motion and the rate at whichit changes by applying the brakes to oneor more wheels individually.
Traction Control
The system enhances your vehicle’s abilityto maintain traction of the wheels bydetecting and controlling wheel spin. SeeUsing Traction Control (page 175).

USING HILL DESCENT
CONTROL
Principle of Operation
WARNINGS
Hill descent control cannot controldescent in all surface conditions andcircumstances, such as ice orextremely 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 of vehiclecontrol, crash or serious injury.
Hill descent control does not providehill hold at 0 mph (0 km/h). Whenstopped, the parking brake must beapplied or the vehicle must be placed inpark (P) or it may roll away.
Hill descent control allows the driver to setand maintain vehicle speed whiledescending steep grades in various surfaceconditions.
Hill descent control can maintain vehiclespeeds on downhill grades between 3 mph(5 km/h) and 20 mph (32 km/h). Above20 mph (32 km/h), the system remainsarmed, but descent speed cannot be setor maintained.
Hill descent control requires a coolingdown interval after sustained use. Theamount of time that the feature canremain active before cooling varies withconditions. The system provides a warningin the message center and a chime soundswhen the system is about to disengage forcooling. At this time, manually apply thebrakes to maintain descent speed.
Using Hill Descent Control
Press and release the hilldescent button in the center ofthe terrain management control.The button illuminates and a chime soundswhen you switch this feature on.
To increase descent speed, press theaccelerator pedal until you reach thedesired speed. To decrease descentspeed, press the brake pedal until youreach the desired speed.
Whether accelerating or decelerating, onceyou reach the desired descent speed,remove your feet from the pedals and hilldescent control maintains the chosenvehicle speed.
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.

PRINCIPLE OF OPERATION
WARNINGS
To help avoid personal injury, pleaseread and understand the limitationsof the system as contained in thissection. Sensing is only an aid for some(generally large and fixed) objects whenmoving on a flat surface at parking speeds.Certain objects with surfaces that absorbultrasonic waves, surrounding vehicle'sparking aid systems, traffic controlsystems, fluorescent lamps, inclementweather, air brakes, and external motorsand fans may also affect the function ofthe sensing system; this may includereduced performance or a false activation.
To help avoid personal injury, alwaysuse caution when in reverse (R) andwhen using the sensing system.
This system is not designed toprevent contact with small or movingobjects. The system is designed toprovide a warning to assist the driver indetecting large stationary objects to avoiddamaging your vehicle. The system maynot detect smaller objects, particularlythose close to the ground.
Certain add-on devices such as largetrailer hitches, bike or surfboard racksand any device that may block thenormal detection zone of the system, maycreate false beeps.
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 withsharp objects.
Note:If your vehicle sustains damage tothe bumper or fascia, leaving it misalignedor bent, the sensing zone may be alteredcausing inaccurate measurement ofobstacles or false alarms.
Note:The sensing system cannot be turnedoff when a MyKey is present. See Principleof Operation (page 46).
Note:If you attach certain add-on devicessuch as a trailer or bike rack, the rear sensingsystem may detect that add-on device andtherefore provide warnings. It is suggestedthat you disable the rear sensing systemwhen you attach an add-on device to yourvehicle to prevent these warnings.
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 throughthe information display menu or from thepop-up message that appears once youshift the transmission into reverse (R). SeeGeneral Information (page 92).
Note:On vehicles with front parking aid youcan use the parking aid switch to switch thesystem off.
If a fault is present in the system, a warningmessage appears in the informationdisplay. See Information Messages(page 103).
REAR PARKING AID
The rear sensors are only active when thetransmission is in reverse (R). As yourvehicle moves closer to the obstacle, therate of the audible warning increases.When the obstacle is less than 10 in(25 cm) away, the warning soundscontinuously. If the system detects astationary or receding object farther than10 in (25 cm) from the corners of thebumper, the tone sounds for only threeseconds. Once the system detects anobject approaching, the warning soundsagain.
