The vehicle may straighten out.Be ready for a second skid if itoccurs.
.Slow down and adjust yourdriving according to weatherconditions. Stopping distancecan be longer and vehiclecontrol can be affected whentraction is reduced by water,snow, ice, gravel, or othermaterial on the road. Learn torecognize warning clues—suchas enough water, ice, or packedsnow on the road to make amirrored surface—and slowdown when you have any doubt.
.Try to avoid sudden steering,acceleration, or braking,including reducing vehicle speedby shifting to a lower gear. Anysudden changes could causethe tires to slide.
Remember: Antilock brakes helpavoid only the braking skid.
Off-Road Driving
Four-wheel-drive vehicles can beused for off-road driving. Vehicleswithout four-wheel drive and
vehicles not equipped with AllTe r r a i n ( AT ) o r O n - O f f R o a d ( O O R )tires must not be driven off-roadexcept on a level, solid surface. Forcontact information about theoriginal equipment tires, see thewarranty manual.
One of the best ways for successfuloff-road driving is to control thespeed.
{Warning
When driving off-road, bouncing
and quick changes in direction
can easily throw you out of
position. This could cause you to
lose control and crash. You and
your passengers should always
wear safety belts.
Before Driving Off-Road
.Have all necessary maintenanceand service work completed.
.Fuel the vehicle, fill fluid levels,and check inflation pressure inall tires, including the spare,if equipped.
.Read all the information aboutfour-wheel-drive vehicles in thismanual.
.Remove any underbody airdeflector, if equipped. Re-attachthe air deflector after off-roaddriving.
.SeeHill Descent Control(HDC)0297
.Know the local laws that apply tooff-road driving.
To g a i n m o r e g r o u n d c l e a r a n c e i fneeded, it may be necessary toremove the front fascia lower airdam. However, driving without theair dam reduces fuel economy.
Caution
Operating the vehicle for
extended periods without the front
fascia lower air dam installed can
cause improper airflow to the
engine. Reattach the front fascia
air dam after off-road driving.

256 Driving and Operating
{Warning
Wet brakes can cause crashes.
They might not work as well in a
quick stop and could cause
pulling to one side. You could
lose control of the vehicle.
After driving through a large
puddle of water or a car/vehicle
wash, lightly apply the brake
pedal until the brakes work
normally.
Flowing or rushing water creates
strong forces. Driving through
flowing water could cause the
vehicle to be carried away. If this
happens, you and other vehicle
occupants could drown. Do not
ignore police warnings and be
very cautious about trying to drive
through flowing water.
Hydroplaning
Hydroplaning is dangerous. Watercan build up under the vehicle'stires so they actually ride on thewater. This can happen if the road iswet enough and you are going fastenough. When the vehicle ishydroplaning, it has little or nocontact with the road.
There is no hard and fast rule abouthydroplaning. The best advice is toslow down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wetweather driving tips include:
.Allow extra following distance.
.Pass with caution.
.Keep windshield wipingequipment in good shape.
.Keep the windshield washer fluidreservoir filled.
.Have good tires with propertread depth. SeeTires0397.
.Turn off cruise control.
Hill and Mountain Roads
Driving on steep hills or throughmountains is different than drivingon flat or rolling terrain. Tips include:
.Keep the vehicle serviced and ingood shape.
.Check all fluid levels and brakes,tires, cooling system, andtransmission.
.Shift to a lower gear when goingdown steep or long hills.
{Warning
Using the brakes to slow the
vehicle on a long downhill slope
can cause brake overheating, can
reduce brake performance, and
could result in a loss of braking.
Shift the transmission to a lower
gear to let the engine assist the
brakes on a steep downhill slope.

turned from ON/RUN to LOCK/OFF,the windows and sunroof continueto work up to 10 minutes or until anydoor is opened. The radio continuesto work for up to 10 minutes or untilthe driver door is opened.
Accessory Power Outlets (APOs)
The vehicle may have AccessoryPower Outlets (APOs) in severallocations. SeePower Outlets0124.
The APOs in the console or centerseat position are powered byRetained Accessory Power (RAP).They will continue to work for up to10 minutes after the key is turnedfrom ON/RUN to LOCK/OFF, or untilthe driver door is opened.
The APOs on the center stack comefrom the factory powered directlyfrom the vehicle battery, and supplyaccessory power at all times,regardless of ignition key position.
If electronic items are left pluggedinto these APOs for long periods oftime with the vehicle off, the vehiclebattery could be drained. Thevehicle may not start if the battery isallowed to drain for an extendedperiod of time.
Engine Coolant Heater
The engine heater can provideeasier starting and better fueleconomy during engine warm-up incold weather conditions at or below✓18 °C (0 °F). Vehicles with anengine heater should be plugged inat least four hours before starting.An internal thermostat in theplug-end of the cord may exist,which will prevent engine coolantheater operation at temperaturesabove✓18 °C (0 °F).
If the vehicle has a diesel engine,see the Duramax dieselsupplement.
To Use the Engine Coolant
Heater
1. Turn off the engine.
2. Open the hood and unwrap theelectrical cord. The cord issecured to the driver sidefender with a clip, next to theengine compartment fuseblock. Carefully remove thewire tie that bundles theelectrical plug. Do not cut theelectrical cord.
Check the heater cord fordamage. If it is damaged, donot use it. See your dealer forareplacement.Inspectthecord for damage yearly.
3. Plug the cord into a normal,grounded 110-volt AC outlet.

Shifting Out of N (Neutral)
To s h i f t o u t o f N ( N e u t r a l ) :
1. Set the parking brake andapply the brake pedal.
2. Turn the ignition to ON/RUNwith the engine off.
3. Shift the transmission toN(Neutral).
4. Turn the transfer case knob tothe desired setting.
After the transfer case hasshifted out of N (Neutral), theN(Neutral) light will goout.
5. Release the parking brake.
6. Start the engine and shift thetransmission to thedesired gear.
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) WarningLight0141.
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.

facing downhill or if the vehicle isfacing uphill and in R (Reverse).There may be situations on minorhills (less than 5% grade) with aloaded vehicle or while pulling atrailer where HSA may activate.
If you release the brake pedal andthen reapply the brake pedal whileHSA is activated, the brake pedaltypically feels firmer with less pedaltravel.
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 spinand assist the driver in maintainingcontrol, especially on slippery roadconditions.
TCS activates if it senses any of thedrive 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 thevehicle wheel brakes to assist thedriver in keeping the vehicle on the
intended path. Trailer Sway Control(TSC) is also on automatically whenthe vehicle is started. SeeTr a i l e rSway Control (TSC)0344.
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 Stuck0258and“Turning the Systems Off andOn”later in this section.
When the transfer case (if equipped)is in Four-Wheel Drive Low, thestability system is automatically
