GENERAL INFORMATION
Note: Occasional brake noise is normal. Ifa metal-to-metal, continuous grinding orcontinuous squeal sound is present, thebrake linings may be worn-out and anauthorized dealer should check them. If thevehicle has continuous vibration or shudderin the steering wheel while braking, anauthorized dealer should check your vehicle.
Note: Brake dust may accumulate on thewheels, even under normal drivingconditions. Some dust is inevitable as thebrakes wear and does not contribute tobrake noise. See Cleaning the Wheels(page 298).
Wet brakes result in reduced brakingefficiency. Gently press the brake pedal afew times when driving from a car wash orstanding water to dry the brakes.
Brake Over Accelerator
In the event the accelerator pedalbecomes stuck or entrapped, apply steadyand firm pressure to the brake pedal toslow the vehicle and reduce engine power.If you experience this condition, apply thebrakes and bring your vehicle to a safestop. Move the transmission to park (P),switch the engine off and apply the parkingbrake. Inspect the accelerator pedal forany interference. If none are found and thecondition persists, have your vehicle towedto the nearest authorized dealer.
Emergency Brake Assist
Emergency brake assist detects when youbrake heavily by measuring the rate atwhich you press the brake pedal. Itprovides maximum braking efficiency aslong as you press the pedal. Emergencybrake assist can reduce stopping distancesin critical situations.
Note:Depending on applicable laws andregulations in the country for which yourvehicle was originally built, your brake lampscould flash during heavy braking. Followingthis, your hazard lights may also flash whenyour vehicle comes to a stop.
Anti-lock Brake System
This system helps you maintain steeringcontrol during emergency stops by keepingthe brakes from locking.
This lamp momentarilyilluminates when you switch theignition on. If the light does notilluminate during start up, remains on orflashes, the anti-lock braking system maybe disabled. Have the system checked byan authorized dealer. If the anti-lock brakesystem is disabled, normal braking is stilleffective.
See Warning Lamps and Indicators(page 93).
Note:Indicators vary depending on region.
This lamp also illuminatesmomentarily when you switchthe ignition on to confirm thelamp is functional. If it does notilluminate when you switch theignition on, or begins to flash atany time, have the system checked by anauthorized dealer. If the brake warninglamp illuminates with the parking brakereleased, have the system checkedimmediately.
HINTS ON DRIVING WITH
ANTI-LOCK BRAKES
The anti-lock brake system does noteliminate the risks when:
•You drive too closely to the vehicle infront of you.
•Your vehicle is hydroplaning.

HILL START ASSIST
WARNING: The system does notreplace the parking brake. When youleave your vehicle, always apply theparking brake and shift the transmissioninto park (P) for automatic transmissionor first gear for manual transmission.
WARNING: You must remain inyour vehicle when the system turns on.At all times, you are responsible forcontrolling your vehicle, supervising thesystem and intervening, if required.Failure to take care may result in the lossof control of your vehicle, seriouspersonal injury or death.
WARNING: The system will turnoff if a malfunction is apparent. Failureto take care may result in the loss ofcontrol of your vehicle, serious personalinjury or death.
The system makes it easier to pull awaywhen your vehicle is on a slope without theneed to use the parking brake.
When the system activates, your vehicleremains stationary on a slope for a fewseconds after you release the brake pedal.This allows you time to move your footfrom the brake to the accelerator pedal.The brakes release when the engine hasdeveloped sufficient torque to prevent yourvehicle from rolling down the slope. Thisis an advantage when pulling away on aslope, for example from a car park ramp,traffic lights or when reversing uphill intoa parking space.
The system activates on any slope thatcauses your vehicle to roll.
Note: There is no warning lamp to indicatethe system is either on or off.
Using Hill Start Assist
1.Press the brake pedal to bring yourvehicle to a complete standstill. Keepthe brake pedal pressed and shift intofirst gear when facing uphill or reverse(R) when facing downhill.
2.The system activates if the sensorsdetect that your vehicle is on a slope.
3.When you remove your foot from thebrake pedal, your vehicle remains onthe slope without rolling away for a fewseconds. This hold time increases if youare in the process of driving off.
4.Pull away in the normal manner.

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: Operating your vehiclewith the traction control disabled couldlead to an increased risk of loss of vehiclecontrol, vehicle rollover, personal injuryand 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
When you switch the system off,a message and an illuminatedicon appear on the instrumentcluster.
Use the switch again to return the tractioncontrol system to normal operation.
The switch for the stability and tractioncontrol system is on the instrument panel.
Your vehicle could have MyKey restrictionsregarding this feature. See What IsMyKey (page 63).
System Indicator Lights andMessages
The stability and traction controllight temporarily illuminates onengine start-up and flashes:
•When a driving condition activateseither of the systems.
•If a problem occurs in either of thesystems.
The stability and traction controloff light temporarily illuminateson engine start-up and stays on:

PRINCIPLE OF OPERATION
WARNING: Vehicle modificationsinvolving braking system, aftermarketroof racks, suspension, steering system,tire construction and wheel and tire sizemay change the handling characteristicsof your vehicle and may adversely affectthe performance of the electronicstability control system. In addition,installing any stereo loudspeakers mayinterfere with and adversely affect theelectronic stability control system. Installany aftermarket stereo loudspeaker asfar as possible from the front centerconsole, the tunnel, and the front seatsin order to minimize the risk of interferingwith the electronic stability controlsensors. Reducing the effectiveness ofthe electronic stability control systemcould lead to an increased risk of loss ofvehicle control, vehicle rollover, personalinjury and death.
WARNING: Remember that evenadvanced technology cannot defy thelaws of physics. It’s always possible tolose control of a vehicle due toinappropriate driver input for theconditions. Aggressive driving on anyroad condition can cause you to losecontrol of your vehicle increasing the riskof personal injury or property damage.Activation of the electronic stabilitycontrol system is an indication that atleast some of the tires have exceededtheir ability to grip the road; this couldreduce the operator’s ability to controlthe vehicle potentially resulting in a lossof vehicle control, vehicle rollover,personal injury and death. If yourelectronic stability control systemactivates, SLOW DOWN.
The system automatically turns on eachtime you switch the ignition on.
If a fault occurs in either the stabilitycontrol or the traction control system, youmay experience the following conditions:
•The stability and traction control lightilluminates steadily.
•The stability control and tractioncontrol systems do not enhance yourvehicle's ability to maintain traction ofthe wheels.
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 system applieshigher brake force.
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.
Traction Control
The system enhances your vehicle’s abilityto maintain traction of the wheels bydetecting and controlling wheel spin. SeeUsing Traction Control (page 174).
