One to Four Shift Message
(V8 Only)
When this message comes on, thevehicle can only be shifted from1(First) to 4(Fourth) instead of1(First) to 2(Second). The messagewill display in the Driver InformationCenter (DIC).
Complete the shift into 4 (Fourth) toturn off this feature. This helps toget the best possible fuel economy.
After shifting to 4 (Fourth), downshiftto a lower gear, if desired.
Caution
Forcing the shift lever into any
gear except 4 (Fourth) when the
1-4 SHIFT message comes on
may damage the transmission.
Shift only from 1 (First) to
4(Fourth) when the message
comes on.
This message will come on when:
.The engine coolant temperatureis higher than 76 °C (169 °F).
.The vehicle is accelerating fromastopandgoing24to31km/h(15 to 19 mph).
.The vehicle is at 33% throttleor less.
Brakes
Antilock Brake
System (ABS)
This vehicle has an Antilock BrakeSystem (ABS), an advancedelectronic braking system that helpsprevent a braking skid.
When the vehicle begins to driveaway, ABS checks itself.Amomentarymotororclickingnoisemay be heard while this test is goingon, and it may even be noticed thatthe brake pedal moves a little. Thisis normal.
If there is a problem with ABS, thiswarning light stays on. SeeAntilockBrake System (ABS) Warning Light0104.

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.

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.

When LDW is on,@is green if
LDW is available to warn of a lanedeparture. If the vehicle crosses adetected lane marking without using
the turn signal in that direction,@
changes to amber and flashes.Additionally, there will be threebeeps on the right or left, dependingon the lane departure direction.
When the System Does Not
Seem to Work Properly
The system may not detect lanes aswell when there are:
.Close vehicles ahead.
.Sudden lighting changes, suchas when driving through tunnels.
.Banked roads.
If the LDW system is not functioningproperly when lane markings areclearly visible, cleaning thewindshield may help.
LDW alerts may occur due totar marks, shadows, cracks inthe road, temporary or constructionlane markings, or other roadimperfections. This is normal systemoperation; the vehicle does not needservice. Turn LDW off if theseconditions continue.
