Neutral and release the clutchpedal. Then press the clutch againand shift into R (Reverse). Do notattempt to shift into 5 (Fifth) prior toshifting into R (Reverse). Thetransmission has a lock out feature,which prevents a 5 (Fifth) gear toR(Reverse) gear shift.
Caution
Shifting to R (Reverse) while the
vehicle is moving forward could
damage the transmission. The
repairs would not be covered by
the vehicle warranty. Shift to
R(Reverse) only after the vehicle
is stopped.
Use R (Reverse), along with theparking brake, for parking thevehicle.
Shift Speeds
{Warning
If you skip a gear when
downshifting, you could lose
control of the vehicle. You could
injure yourself or others. Do not
shift down more than one gear at
atimewhendownshifting.
Drive Systems
Four-Wheel Drive
If equipped, four-wheel driveengages the front axle for extratraction. Read the appropriatesection for transfer case operationbefore using.
Caution
Do not drive on clean, dry
pavement in 4mand 4n(if
equipped) for an extended period
of time. These conditions may
cause premature wear on the
vehicle’spowertrain.
Driving on clean, dry pavement in4HI or 4LO may:
.Cause a vibration to be felt inthe steering system.
.Cause tires to wear faster.
.Make the transfer case harder toshift, and cause it to run noisier.

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.

Trailer Sway
Control (TSC)
Vehicles with StabiliTrak have aTrailer Sway Control (TSC) feature.Trailer sway is unintendedside-to-side motion of a trailer whilebeing towed. If the vehicle is towingatrailerandtheTSCdetectsthatsway is increasing, the vehiclebrakes are selectively applied ateach wheel, to help reduceexcessive trailer sway. If the vehicleis equipped with the IntegratedTrailer Brake Control (ITBC) system,and the trailer has the electricactuated brake system, StabiliTrakmay also apply the trailer brakes.
If TSC is enabled, the TractionControl System (TCS)/StabiliTrakwarning light will flash on theinstrument cluster. Vehicle speedmust be reduced. If trailer swaycontinues, StabiliTrak can reduceengine torque to help slow thevehicle. SeeTr a c t i o n C o n t r o l /Electronic Stability Control0295.
{Warning
Even if the vehicle is equipped
with TSC, trailer sway could result
in loss of control and the vehicle
could crash. If excessive trailer
sway is detected, slow down to a
safe speed. Check the trailer and
