{Warning
Driving to the top of a hill at high
speed can cause an accident.
There could be a drop-off,
embankment, cliff, or even
another vehicle. You could be
seriously injured or killed. As you
near the top of a hill, slow down
and stay alert.
.Never go downhill forward orbackward with either thetransmission or transfer case inN(Neutral).Thebrakescouldoverheat and you could losecontrol.
{Warning
If the vehicle has the two⇣speed

transfer case overrides the
transmission. You or someone
else could be injured. If leaving
the vehicle, set the parking brake
and shift the transmission to
P(Park).Shiftthetransfercaseto
any position but N (Neutral).
.When driving down a hill, keepthe vehicle headed straightdown. Use a low gear becausethe engine will work with thebrakes to slow the vehicle andhelp keep the vehicle undercontrol.
{Warning
Heavy braking when going down
ahillcancauseyourbrakesto
overheat and fade. This could
cause loss of control and you or
others could be injured or killed.

descending a hill and use a low
gear to keep vehicle speed under
control.
If the vehicle stalls on a hill:
1. Apply the brakes to stop thevehicle, and then apply theparking brake.
2. Shift into P (Park) and thenrestart the engine.
.If driving uphill when thevehicle stalls, shift toR(Reverse),releasetheparking brake, and backstraight down.
.Never try to turn the vehiclearound. If the hill is steepenough to stall the vehicle,it is steep enough to causeit to roll over.
.If you cannot make it up thehill, back straight downthe hill.

.Never back down a hill inN(Neutral)usingonlythebrake. The vehicle can rollbackward quickly and youcould lose control.
.If driving downhill when thevehicle stalls, shift to alower gear, release theparking brake, and drivestraight down the hill.
3. If the vehicle cannot berestarted after stalling, set theparking brake, shift intoP(Park),andturnthevehicle off.
3.1. Leave the vehicle andseek help.
3.2. Stay clear of the path thevehicle would take if itrolled downhill.
.Avoid turns that take the vehicleacross the incline of the hill.Ahillthatcanbedrivenstraightup or down might be too steep todrive across. Driving across anincline puts more weight on the
downhill wheels, which couldcause a downhill slide or arollover.
.Surface conditions can be aproblem. Loose gravel, muddyspots, or even wet grass cancause the tires to slip sideways,downhill. If the vehicle slipssideways, it can hit somethingthat will trip it—arock,arut,etc.—and roll over.
.Hidden obstacles can make thesteepness of the incline moresevere. If a rock is driven acrosswith the uphill wheels, or if thedownhill wheels drop into a rutor depression, the vehicle can tilteven more.
.If an incline must be drivenacross, and the vehicle starts toslide, turn downhill. This shouldhelp straighten out the vehicleand prevent the side slipping.
{Warning
Getting out of the vehicle on the
downhill side when stopped
across an incline is dangerous.
If the vehicle rolls over, you could
be crushed or killed. Always get
out on the uphill side of the
vehicle and stay well clear of the
rollover path.
Driving in Mud, Sand, Snow,
or Ice
Use a low gear when driving inmud—the deeper the mud, thelower the gear. Keep the vehiclemoving to avoid getting stuck.
Traction changes when driving onsand. On loose sand, such as onbeaches or sand dunes, the tirestend to sink into the sand. Thisaffects steering, accelerating, andbraking. Drive at a reduced speedand avoid sharp turns or abruptmaneuvers.

Ignition Positions
The ignition switch has four differentpositions.
To s h i f t o u t o f P ( P a r k ) , t h e i g n i t i o nmust be in ON/RUN or ACC/ACCESSORY and the regular brakepedal must be applied.
0(STOPPINGTHEENGINE/LOCK/OFF) :When the vehicle is stopped,turn the ignition switch to LOCK/OFF to turn the engine off. RetainedAccessory Power (RAP) will remainactive. SeeRetained AccessoryPower (RAP)0271.
This position locks the ignition andsteering wheel. It also locks thetransmission on automatictransmission vehicles. The key canbe removed in LOCK/OFF.
The steering can bind with thewheels turned off center. If thishappens, move the steering wheelfrom right to left while turning thekey to ACC/ACCESSORY. If thisdoes not work, then the vehicleneeds service.
Do not turn the engine off when thevehicle is moving. This will cause aloss of power assist in the brakeand steering systems and disablethe airbags.
If the vehicle must be shut off in anemergency:
1. Brake using a firm and steadypressure. Do not pump thebrakes repeatedly. This maydeplete power assist, requiringincreased brake pedal force.
2. Shift the vehicle to N (Neutral).This can be done while thevehicle is moving. After shiftingto N (Neutral), continue to

the way the engine operates. Any
resulting damage would not be
covered by the vehicle warranty.
SeeAdd-On Electrical
Equipment0345.
Caution
If the steering wheel is turned
until it reaches the end of its
travel, and is held in that position
while starting the vehicle, damage
may occur to the power steering
system and there may be loss of
power steering assist.
Place the transmission in theproper gear.
Automatic Transmission
Move the shift lever to P (Park) orN(Neutral). To restart the enginewhen the vehicle is already moving,use N (Neutral) only.
Caution
Do not try to shift to P (Park) if the
vehicle is moving. If you do, you
could damage the transmission.
Shift to P (Park) only when the
vehicle is stopped.
Manual Transmission
The shift lever should be in Neutraland the parking brake engaged.Hold the clutch pedal down to thefloor and start the engine.
Starting Procedure
1. With your foot off theaccelerator pedal, turn theignition key to START. Whenthe engine starts, let go of thekey. The idle speed will godown as the engine gets warm.Do not race the engineimmediately after starting it.
Operate the engine andtransmission gently to allow theoil to warm up and lubricate allmoving parts.
When the low fuel warning lightis on and the FUEL LEVELLOW message is displayed inthe Driver Information Center(DIC), hold the ignition switchin the START position tocontinue engine cranking.
Caution
Cranking the engine for long
periods of time, by returning the
ignition to the START position
immediately after cranking has
ended, can overheat and damage
the cranking motor, and drain the
battery. Wait at least 15 seconds
between each try, to let the
cranking motor cool down.
2. If the engine does not startafter five to 10 seconds,especially in very cold weather(below✓18 °C or 0 °F), it couldbe flooded with too much

{Warning
If you have four-wheel drive, the
vehicle will be free to roll—even
if the shift lever is in P (Park)—if
the transfer case is in N (Neutral).
So, be sure the transfer case is in
adrivegear,Two-WheelDrive
High or Four-Wheel Drive High or
Four-Wheel Drive Low—not in
N(Neutral). SeeShifting Into
Park0273.
R:Use this gear to back up.
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.
To r o c k t h e v e h i c l e b a c k a n d f o r t h t oget out of snow, ice, or sand withoutdamaging the transmission, seeIfthe Vehicle Is Stuck0258.
N:In this position, the engine doesnot connect with the wheels. Torestart when you are alreadymoving, use N (Neutral) only. Also,use N (Neutral) when the vehicle isbeing towed.
{Warning
Shifting into a drive gear while the
engine is running at high speed is
dangerous. Unless your foot is
firmly on the brake pedal, the
vehicle could move very rapidly.
Yo u c o u l d l o s e c o n t r o l a n d h i t
people or objects. Do not shift
into a drive gear while the engine
is running at high speed.
Caution
Shifting out of P (Park) or
N(Neutral) with the engine
running at high speed may
damage the transmission. The
repairs would not be covered by
the vehicle warranty. Be sure the
engine is not running at high
speed when shifting the vehicle.
D:This position is for normaldriving. It provides the best fueleconomy. If you need more powerfor passing, and you are:
.Going less than about 55 km/h(35 mph), push the acceleratorpedal about halfway down.
.Going about 55 km/h (35 mph) ormore, push the accelerator allthe way down.
By doing this, the vehicle shiftsdown to the next gear and hasmore power.
Use D (Drive) and Tow/Haul Modewhen towing a trailer, carrying aheavy load, driving on steep hills,

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.
