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.

{Warning
Snow can trap engine exhaust
under the vehicle. This may
cause exhaust gases to get
inside. Engine exhaust contains
carbon monoxide (CO), which
cannot be seen or smelled. It can
cause unconsciousness and even
death.
If the vehicle is stuck in snow:
.Clear snow from the base ofthe vehicle, especially anyblocking the exhaust pipe.
.Open a window about 5 cm(2 in) on the vehicle sidethat is away from the wind,to bring in fresh air.
.Fully open the air outlets onor under the instrumentpanel.
.Adjust the climate controlsystem to circulate the airinside the vehicle and set

For more information about CO,
seeEngine Exhaust0276.
To s a v e f u e l , r u n t h e e n g i n e f o rshort periods to warm the vehicleand then shut the engine off andpartially close the window. Movingabout to keep warm also helps.
If it takes time for help to arrive,when running the engine, push theaccelerator pedal slightly so theengine runs faster than the idlespeed. This keeps the batterycharged to restart the vehicle and tosignal for help with the headlamps.Do this as little as possible, tosave fuel.
If the Vehicle Is Stuck
Slowly and cautiously spin thewheels to free the vehicle whenstuck in sand, mud, ice, or snow.See“Rocking the Vehicle to Get ItOut”later in this section.
The Traction Control System (TCS)can often help to free a stuckvehicle. SeeTr a c t i o n C o n t r o l /Electronic Stability Control0295.If TCS cannot free the vehicle, see“Rocking the Vehicle to Get it Out”following.
{Warning
If the vehicle's tires spin at high
speed, they can explode, and you
or others could be injured. The
vehicle can overheat, causing an
engine compartment fire or other
damage. Spin the wheels as little
as possible and avoid going
above 56 km/h (35 mph).

Running the Vehicle
While Parked
It is better not to park with theengine running.
If the vehicle is left with the enginerunning, follow the proper steps tobe sure the vehicle will not move.SeeShifting Into Park0273andEngine Exhaust0276.Ifthevehiclehas a manual transmission, seeParking (ManualTr a n s m i s s i o n )0275.
If parking on a hill and pulling atrailer, seeDriving Characteristicsand Towing Tips0315.
Automatic
Transmission
If equipped, there is an electronicshift lever position indicator withinthe instrument cluster. This displaycomes on when the ignition key isturned to the ON/RUN position.
There are several different positionsfor the shift lever.

Similar
See“Range Selection Mode”underManual Mode0280.
P:This position locks the rearwheels. It is the best position to usewhen starting the engine becausethe vehicle cannot move easily.When parked on a hill, especiallywhen the vehicle has a heavy load,you might notice an increase in the
effort to shift out of P (Park). See“To r q u e L o c k”underShifting IntoPark0273.
{Warning
It is dangerous to get out of the
vehicle if the shift lever is not fully
in P (Park) with the parking brake
firmly set. The vehicle can roll.
Do not leave the vehicle when the
engine is running. If you have left
the engine running, the vehicle
can move suddenly. You or others
could be injured. To be sure the
vehicle will not move, even when
you are on fairly level ground,
always set the parking brake and
move the shift lever to P (Park).

or driving off-road. Shift thetransmission to a lower gearselection if the transmission shiftstoo often.
Downshifting the transmission inslippery road conditions could resultin skidding. See“Skidding”underLoss of Control0250.
The vehicle has a shift stabilizationfeature that adjusts the transmissionshifting to the current drivingconditions in order to reduce rapidupshifts and downshifts. This shiftstabilization feature is designed todetermine, before making anupshift, if the engine is able tomaintain vehicle speed by analyzingthings such as vehicle speed,throttle position, and vehicle load.If the shift stabilization featuredetermines that a current vehiclespeed cannot be maintained, thetransmission does not upshift andinstead holds the current gear.In some cases, this could appear tobe a delayed shift, however thetransmission is operating normally.
The transmission uses adaptiveshift controls. The adaptive shiftcontrol process continuallycompares key shift parameters topre-programmed ideal shifts storedin the transmission’scomputer.Thetransmission constantly makesadjustments to improve vehicleperformance according to how thevehicle is being used, such as withaheavyloadorwhenthetemperature changes. During thisadaptive shift control process,shifting might feel different as thetransmission determines the bestsettings.
When temperatures are very cold,the transmission's gear shiftingcould be delayed providing morestable shifts until the engine warmsup. Shifts could be more noticeablewith a cold transmission. Thisdifference in shifting is normal.
M:This position allows selection ofarangeofgearsappropriateforcurrent driving conditions.If equipped, see“Range SelectionMode”underManual Mode0280.
Caution
Spinning the tires or holding the
vehicle in one place on a hill
using only the accelerator pedal
may damage the transmission.
The repair will not be covered by
the vehicle warranty. If you are
stuck, do not spin the tires. When
stopping on a hill, use the brakes
to hold the vehicle in place.
Normal Mode Grade Braking
If equipped with a gasoline engineand an automatic transmission,Normal Mode Grade Braking isenabled when the vehicle is started,but is not enabled in RangeSelection Mode. It assists inmaintaining desired vehicle speedswhen driving on downhill grades byusing the engine and transmissionto slow the vehicle. The first timethe system engages for eachignition key cycle, a DIC messagewill be displayed. SeeTr a n s m i s s i o nMessages0157.

Kickdown Mode
If equipped, the accelerator pedalprovides an additional downshiftafter pressing through the kickdownfeature.
It requires extra pedal pressure nearthe end of its travel to engage.
Manual Mode
Range Selection Mode
If equipped, Range Selection Modehelps control the vehicle'stransmission and vehicle speedwhile driving downhill or towing atrailer by letting you select a desiredrange of gears.
To u s e t h i s f e a t u r e :
1. Move the shift lever toL(ManualMode).
2. Press the plus/minus buttonson the shift lever to select thedesired range of gears forcurrent driving conditions.
With an 8-speed automatictransmission, hold the plus/minusbuttons on the shift lever to selectthe highest or lowest rangeavailable for the current vehiclespeed.
When the shift lever is moved fromD(Drive) to L(Manual Mode), anumber displays next to the L,indicating the current transmissionrange.
This number is the highest gear thatthe transmission will command whileoperating in L (Manual Mode). Allgears below that number areavailable. As driving conditionschange, the transmission canautomatically shift to lower gears.For example, when L5 is selected,1(First) through 5(Fifth) gears areautomatically shifted by thetransmission, but 6 (Sixth) cannot beused until the plus/minus button onthe shift lever is used to change tothe range.

Using the Manual Transfer Case
.Use quick motions to shift into or
out of 4nor N (Neutral).
.Shifting may be harder when thevehicle is cold, but will return tonormal once warmed up.
.Four-wheel drive reduces fueleconomy.
Shifting from 2mto 4m
.Shifts can be made at anyvehicle speed.
.Shift in one continuous motion.
.Shifting while the vehicle is inmotion may require thatmoderate force be applied to the
shift lever before 4mcan be
engaged, especially in coldweather.
.In extremely cold weather, it maybe necessary to slow or stop thevehicle to shift.
.While in 4m,thevehiclecanbe
driven at any posted legal speedlimit.
Shifting In or Out of 4n
Caution
Shifting the transfer case into 4n
while moving at speeds faster
than 5 km/h (3 mph) may cause
premature wear to the transfer
case, and may cause the gears to
grind.
1. If possible, shift with thevehicle moving 5 km/h (3 mph)or less.
2. Shift the transmission intoN(Neutral).
3. Shift the transfer case shiftlever in one continuous motion.
4. Shifting with the vehicle at astop may be more difficult. It ispossible that the shift will notcomplete and the transfer casewill remain in N (Neutral). Thisis normal. To complete theshift, with the engine running,shift the transmission to
D(Drive) and back toN(Neutral), and reattempt thetransfer case shift.
Shifting In or Out of N (Neutral)
1. Have the engine running.

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
