242 Driving and Operating
If driving safely on a wet road and itbecomes necessary to slam on thebrakes and continue braking toavoid a sudden obstacle, acomputer senses the wheels areslowing down. If one of the wheelsis about to stop rolling, the computerwill separately work the brakes ateach wheel.
ABS can change the brake pressureto each wheel, as required, fasterthan any driver could. This can helpyou steer around the obstacle whilebraking hard.
As the brakes are applied, thecomputer keeps receiving updateson wheel speed and controlsbraking pressure accordingly.
Remember: ABS does not changethe time needed to get a foot up tothe brake pedal or always decreasestopping distance. If you get tooclose to the vehicle in front of you,there will not be enough time toapply the brakes if that vehiclesuddenly slows or stops. Alwaysleave enough room up ahead tostop, even with ABS.
Using ABS
Do not pump the brakes. Just holdthe brake pedal down firmly and letABS work. You may hear the ABSpump or motor operating and feelthe brake pedal pulsate. This isnormal.
Braking in Emergencies
ABS allows you to steer and brakeat the same time. In manyemergencies, steering can helpmore than even the very bestbraking.
Electric Parking Brake
The vehicle has an Electric ParkingBrake (EPB). The switch is on thecenter console. The EPB canalways be activated, even if theignition is off. To prevent drainingthe battery, avoid repeated cycles ofthe EPB when the engine is notrunning.
The system has a red parking brakestatus light and an amber parkingbrake warning light. SeeElectricParking Brake Light0103andService Electric Parking Brake Light0103.Therearealsoparkingbrake-related Driver InformationCenter (DIC) messages. SeeBrakeSystem Messages011 3.Incaseofinsufficient electrical power, the EPBcannot be applied or released.
Before leaving the vehicle, checkthe red parking brake status light toensure that the parking brake isapplied.
EPB Apply
To a p p l y t h e E P B :
1. Be sure the vehicle is at acomplete stop.

2. Lift up the EPB switchmomentarily.
The red parking brake status lightwill flash and then stay on once theEPB is fully applied. If the redparking brake status light flashescontinuously, then the EPB is onlypartially applied or there is aproblem with the EPB. A DICmessage will display. Release theEPB and try to apply it again. If thelight does not come on, or keepsflashing, have the vehicle serviced.Do not drive the vehicle if the redparking brake status light is flashing.See your dealer. SeeElectricParking Brake Light0103.
If the amber parking brake warninglight is on, lift up on the EPB switchand hold it up. Continue to hold theswitch until the red parking brakestatus light remains on. If the amberparking brake warning light remainson, see your dealer.
If the EPB is applied while thevehicle is moving, the vehicle willdecelerate as long as the switch is
held up. If the switch is held up untilthe vehicle comes to a stop, theEPB will remain applied.
If the EPB fails to apply, the rearwheels should be blocked toprevent vehicle movement.
EPB Release
To r e l e a s e t h e E P B :
1. Place the ignition in the ACC/ACCESSORY or ON/RUNposition.
2. Apply and hold the brakepedal.
3. Push down momentarily on theEPB switch.
The EPB is released when the redparking brake status light is off.
If the amber parking brake warninglight is on, release the EPB bypushing down on the EPB switchand holding it down. Continue tohold the switch until the red parkingbrake status light is off. If either lightstays on after release is attempted,see your dealer.
Caution
Driving with the parking brake on
can overheat the brake system
and cause premature wear or
damage to brake system parts.
Make sure that the parking brake
is fully released and the brake
warning light is off before driving.
Automatic EPB Release
The EPB will automatically release ifthe vehicle is running, placed intogear, and an attempt is made todrive away. Avoid rapid accelerationwhen the EPB is applied, topreserve parking brake lining life.
The EPB can also be used toprevent roll back for vehicles with amanual transmission taking off on ahill. When no roll back is desired, anapplied EPB will allow both feet tobe used for the clutch andaccelerator pedals in preparation forstarting the vehicle moving in theintended direction. In this case,there is no need to push the switchto release the EPB.

244 Driving and Operating
Brake Assist
The Brake Assist feature isdesigned to assist the driver instopping or decreasing vehiclespeed in emergency drivingconditions. This feature uses thestability system hydraulic brakecontrol module to supplement thepower brake system underconditions where the driver hasquickly and forcefully applied thebrake pedal in an attempt to quicklystop or slow down the vehicle. Thestability system hydraulic brakecontrol module increases brakepressure at each corner of thevehicle until the ABS activates.Minor brake pedal pulsation orpedal movement during this time isnormal and the driver shouldcontinue to apply the brake pedal asthe driving situation dictates. TheBrake Assist feature willautomatically disengage when thebrake pedal is released or brakepedal pressure is quicklydecreased.
Hill Start Assist (HSA)
This vehicle has a Hill Start Assist(HSA) feature, which may be usefulwhen the vehicle is stopped on agrade sufficient enough to activateHSA. This feature is designed toprevent the vehicle from rolling,either forward or rearward, duringvehicle drive off. After the drivercompletely stops and holds thevehicle in a complete standstill on agrade, HSA will be automaticallyactivated. During the transitionperiod between when the driverreleases the brake pedal and startsto accelerate to drive off on a grade,HSA holds the braking pressure foramaximumoftwosecondstoensure that there is no rolling. Thebrakes will automatically releasewhen the accelerator pedal isapplied within the two-secondwindow.
HSA will not activate if the vehicle isin a forward gear position and facingdownhill, or if the vehicle is facinguphill and the gear position is inR(Reverse).Whenbackingdownahill, select R (Reverse) todisable HSA.

Ride Control Systems
Traction Control/
Electronic Stability
Control
System Operation
The vehicle has a Traction ControlSystem (TCS) and StabiliTrak®,anelectronic stability control system.These systems help limit wheel slipand assist the driver in maintainingcontrol, especially on slippery roadconditions.
TCS activates if it senses that anyof the drive wheels are spinning orbeginning to lose traction. When thishappens, TCS applies the brakes tothe spinning wheels and reducesengine power to limit wheel spin.
StabiliTrak activates when thevehicle senses a difference betweenthe intended path and the directionthe vehicle is actually traveling.StabiliTrak selectively appliesbraking pressure to any one of the
vehicle wheel brakes to assist thedriver in keeping the vehicle on theintended path.
If cruise control is being used andtraction control or StabiliTrak beginsto limit wheel spin, cruise control willdisengage. Cruise control may beturned back on when roadconditions allow.
Both systems come onautomatically when the vehicle isstarted and begins to move. Thesystems may be heard or felt whilethey are operating or whileperforming diagnostic checks. Thisis normal and does not mean thereis a problem with the vehicle.
It is recommended to leave bothsystems on for normal drivingconditions, but it may be necessaryto turn TCS off if the vehicle getsstuck in sand, mud, ice, or snow.SeeIf the Vehicle Is Stuck0225and“Turning the Systems Off andOn”later in this section.
The indicator light for both systemsis in the instrument cluster. Thislight will:
.Flash when TCS is limitingwheel spin.
.Flash when StabiliTrak isactivated.
.Turn on and stay on when eithersystem is not working.
If either system fails to turn on or toactivate, a message displays in theDriver Information Center (DIC),
anddcomes on and stays on to
indicate that the system is inactiveand is not assisting the driver inmaintaining control. The vehicle issafe to drive, but driving should beadjusted accordingly.
Ifdcomes on and stays on:
1. Stop the vehicle.

Track Driver Mode
Track Driver Mode and LaunchControl are systems designed toallow increased performance whileaccelerating and/or cornering. Thisis accomplished by regulating andoptimizing the engine, brakes, andsuspension performance. Thesemodes are for use at a closedcourse race track and are notintended for use on public roads.These systems will not compensatefor driver inexperience or lack offamiliarity with the race track.
{Warning
Track Driver Mode and Launch
Control change the way
StabiliTrak and TCS perform and
should not be used on public
roads. These modes should only
be used on closed courses by
experienced drivers.
Caution
Attempting to shift when the drive
wheels are spinning and do not
have traction may cause damage
to the transmission. Damage
caused by misuse of the vehicle
is not covered by the vehicle
warranty. Do not attempt to shift
when the drive wheels do not
have traction.
Racing will result in the prematurewear of brakes, tires, and drivelinecomponents. Inspect and replacecomponents as necessary.

After the vehicle is launched, thesystem continues in TrackDriver Mode.
Limited-Slip Rear Axle
Vehicles with a limited-slip rear axlecan give more traction on snow,mud, ice, sand, or gravel. Whentraction is low, this feature allowsthe drive wheel with the mosttraction to move the vehicle. Thelimited-slip rear axle also gives thedriver enhanced control whencornering hard or completing amaneuver, such as a lane change.For vehicles with a limited-slip rearaxle, driven under severeconditions, the rear axle fluid shouldbe changed. SeeTr a c k D r i v e r M o d e0249andMaintenance Schedule0349.
Cruise Control
With cruise control, the vehicle canmaintain a speed of about 40 km/h(25 mph) or more without keepingyour foot on the accelerator. Cruisecontrol does not work at speedsbelow 40 km/h (25 mph).
{Warning
Cruise control can be dangerous
where you cannot drive safely at
asteadyspeed.Donotuse
cruise control on winding roads or
in heavy traffic.
Cruise control can be dangerous
on slippery roads. On such roads,
fast changes in tire traction can
cause excessive wheel slip, and
you could lose control. Do not use
cruise control on slippery roads.
If the vehicle has the StabiliTrak®
system and begins to limit wheelspin while using cruise control, thecruise control will automaticallydisengage. SeeTr a c t i o n C o n t r o l /Electronic Stability Control0245.
When road conditions allow you tosafely use it again, the cruisecontrol can be turned back on.
If the brakes are applied, cruisecontrol disengages.

shortly following the release tooverride cruise control, brieflymoving the thumbwheel towardSET/–will result in cruise control setto the current vehicle speed.
Using Cruise Control on Hills
How well the cruise control workson hills depends upon the vehiclespeed, load, and the steepness ofthe hills. When going up steep hills,you might have to step on theaccelerator pedal to maintain thevehicle speed. When goingdownhill, you might have to brake orshift to a lower gear to keep yourspeed down. If the brake pedal isapplied, cruise control willdisengage.
Ending Cruise Control
There are four ways to disengagecruise control:
.Step lightly on the brake pedalor clutch for a manualtransmission.
.Press*.
.Shift the transmission toN(Neutral).
