290 Driving and Operating
AUTO (Automatic Four-WheelDrive) :Use when road surfacetraction conditions are variable.When driving in AUTO, the frontaxle is engaged, and the vehicle'spower is sent to the front and rearwheels automatically based ondriving conditions. This settingprovides slightly lower fuel economy
than 2m.
Do not use AUTO mode,if equipped, to park on a steepgrade with poor traction such as ice,snow, mud, or gravel. In AUTOmode only the rear wheels will holdthe vehicle from sliding whenparked. If parking on a steep grade,
use 4mto keep all four wheels
engaged.
4m(Four-Wheel Drive High) :Use
this position when extra traction isneeded, such as when driving onsnowy or icy roads, whenoff-roading, or when plowing snow.
4n(Four-Wheel Drive Low) :This
setting engages the front axle and
delivers extra torque. Choose 4n
when driving off-road in deep sand,deep mud, or deep snow, and whileclimbing or descending steep hills.
Shifting into 4nwill turn Traction
Control and StabiliTrak off. SeeTr a c t i o n C o n t r o l / E l e c t r o n i c S t a b i l i t yControl0295.

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.

Driving and Operating 293
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.
Parking Brake
For vehicles without a releasehandle, set the parking brake byholding the regular brake pedaldown, then pushing down theparking brake pedal.
If the ignition is on, the brakesystem warning light will come on.SeeBrake System WarningLight0140.
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.
To r e l e a s e t h e p a r k i n g b r a k e , h o l dthe regular brake pedal down, thenpush down momentarily on theparking brake pedal until you feelthe pedal release. Slowly pull yourfoot up off the parking brake pedal.If the parking brake is not releasedwhen you begin to drive, the brake
system warning light will flash and achime will sound warning you thatthe parking brake is still on.
If you are towing a trailer and areparking on a hill, seeDrivingCharacteristics and TowingTips0315.
For vehicles with a release handle,set the parking brake by holding theregular brake pedal down, thenpushing down the parking brakepedal.
If the ignition is on, the brakesystem warning light will come on.SeeBrake System WarningLight0140.

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. This feature is designed toprevent the vehicle from rolling,either forward or rearward, duringvehicle drive off. After youcompletely stop and hold the vehiclein a complete standstill on a grade,HSA will automatically activate.During the transition period betweenwhen you release the brake pedaland start to accelerate to drive offon a grade, HSA holds the brakingpressure for a maximum oftwo seconds to ensure that there isno rolling. The brakes willautomatically release when theaccelerator pedal is applied withinthe two-second window. If thevehicle is equipped with theIntegrated Trailer Brake Control(ITBC) system, HSA may also applythe trailer brakes. It will not activateif the vehicle is in a drive gear and

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

appropriate message will appear onthe DIC. Both traction control andStabiliTrak are automaticallydisabled in this condition.
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 toindicate that the system is inactiveand is not assisting the driver in
maintaining control. The vehicle issafe to drive, but driving should beadjusted accordingly.
Ifdcomes on and stays on:
1. Stop the vehicle.
2. Turn the engine off and wait15 seconds.
3. Start the engine.
Drive the vehicle. Ifdcomes on
and stays on, the vehicle may needmore time to diagnose the problem.If the condition persists, see yourdealer.

Hill Descent
Control (HDC)
If equipped, HDC can be used whendriving downhill. It sets andmaintains vehicle speed whiledescending a very steep incline in aforward or reverse gear.
The HDC switch is on the centerstack, below the climate controls.
Press5to enable or disable HDC.
Vehicle speed must be below50 km/h (31 mph).
The HDC light displays on theinstrument cluster when enabled.
HDC can maintain vehicle speedsbetween 3 and 22 km/h (2 and14 mph) on an incline greater thanor equal to a 10% grade. A blinkingHDC light indicates the system isactively applying the brakes tomaintain vehicle speed.
When HDC is activated, the initialHDC speed is set to the currentdriving speed. It can be increased ordecreased by pressing the +RES orSET- steering wheel controls or byapplying the accelerator or brakepedal. This adjusted speedbecomes the new set speed.
HDC will remain enabled between22 and 60 km/h (14 and 37 mph);however vehicle speed cannot beset or maintained in this range.It will automatically disable if thevehicle speed is above 80 km/h(50 mph) or above 60 km/h
(37 mph) for at least 30 seconds.5
must be pressed again tore-enable HDC.

Locking Rear Axle
Vehicles with a locking rear axle cangive more traction on snow, mud,ice, sand, or gravel. It works like astandard axle most of the time, butwhen traction is low, this feature willallow the rear wheel with the mosttraction to move the vehicle.
Cruise Control
{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.
With cruise control a speed of about40 km/h (25 mph) or more can bemaintained without keeping yourfoot on the accelerator. Cruisecontrol does not work at speedsbelow about 40 km/h (25 mph).
If equipped with an Allison orHydra-Matic 6-speed automatictransmission, see“To w / H a u l M o d eGrade Braking”underTo w / H a u lMode0282for an explanation of
how cruise control interacts with theRange Selection Mode, Tow/HaulMode, and Grade Braking systems.
If the cruise control is being usedand the Traction Control system(TCS) or StabiliTrak begins to limitwheel spin, the cruise control willautomatically disengage. SeeTr a c t i o n C o n t r o l / E l e c t r o n i c S t a b i l i t yControl0295.Whenroadconditions allow you to safely use itagain, cruise control can be turnedback on.
If the brakes are applied, cruisecontrol disengages.
