Leaving the Vehicle with the
Engine Running (Automatic
Transmission)
{Warning
It can be dangerous to leave the
vehicle with the engine running.
It could overheat and catch fire.
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).
SeeShifting Into Park (Automatic
Tr a n s m i s s i o n )0187.
If you have to leave the vehicle withthe engine running, be sure thevehicle is in P (Park) and the
parking brake is firmly set beforeyou leave it. After you have movedthe shift lever into P (Park), hold thebrake pedal down. Then see if youcan move the shift lever away fromP(Park) without first pushing thebutton on the shift lever. If you can,it means that the shift lever was notfully locked into P (Park).
Torque Lock (Automatic
Transmission)
If you are parking on a hill and youdo not shift the transmission intoP(Park) properly, the weight of thevehicle may put too much force onthe parking pawl in thetransmission. You may find it difficultto pull the shift lever out of P (Park).This is called“torque lock.”To p r e v e n t t o r q u e l o c k , s e t t h eparking brake and then shift intoP(Park) properly before you leavethe driver seat. To find out how, see“Shifting Into Park”previously in thissection.
When you are ready to drive, movethe shift lever out of P (Park) beforeyou release the parking brake.
If torque lock does occur, you mayneed to have another vehicle pushyours a little uphill to take some ofthe pressure from the parking pawlin the transmission, so you can pullthe shift lever out of P (Park).
Shifting out of Park
(Automatic Transmission)
This vehicle is equipped with a shiftlock control. The shift lock control isdesigned to:
.Prevent ignition key removalunless the shift lever is inP(Park) with the shift leverbutton fully released.
.Prevent movement of the shiftlever out of P (Park) unless theignition is in ON/RUN and thebrake pedal is applied.
The shift lock control is alwaysfunctional except in the case of anuncharged or low voltage (less than9-volt) battery.

Driving and Operating 189
If the vehicle has an unchargedbattery or a battery with low voltage,try charging or jump starting thebattery. SeeJump Starting - NorthAmerica0275.
To s h i f t o u t o f P ( P a r k ) :
1. Apply the brake pedal.
2. Turn the ignition to ON/RUN.
3. Press the shift lever button.
4. Move the shift lever to thedesired position.
If still unable to shift out of P (Park):
1. Fully release the shift leverbutton.
2. Hold the brake pedal down andpress the shift lever buttonagain.
3. Move the shift lever to thedesired position.
If you still cannot move the shiftlever from P (Park), consult yourdealer or a professional towingservice.
The doors may lock when shiftingfrom P (Park). SeeAutomatic DoorLocks040.
Parking
If the vehicle has a manualtransmission, before getting out ofthe vehicle, move the shift lever intoR(Reverse) if parking on a downhillslope. On a level surface or anuphill slope, use 1 (First) gear.Firmly apply the parking brake. Turnthe wheels toward the curb for adownhill slope, or away from thecurb for an uphill slope. Once theshift lever has been placed into gearwith the clutch pedal pressed in,turn the ignition key to LOCK/OFF,remove the key, and release theclutch.
Parking over Things
That Burn
{Warning
Things that can burn could touch
hot exhaust parts under the
vehicle and ignite. Do not park
over papers, leaves, dry grass,
or other things that can burn.
Extended Parking
It is better not to park with thevehicle running. If the vehicle is leftwhile running, follow the propersteps to be sure the vehicle will notmove and there is adequateventilation. SeeShifting Into Park(Automatic Transmission)0187andEngine Exhaust0190.
If the vehicle is left in P (Park) whilerunning and the Remote KeylessEntry (RKE) transmitter is outsidethe vehicle, the vehicle will turn offafter one hour.
If the vehicle is left in P (Park) whilerunning and the RKE transmitter isinside, the vehicle will run for twohours. At the end of the secondhour, the vehicle will turn off.

Make sure the shift lever is fully inP(Park) before starting the engine.The vehicle has a shift lock control.Yo u m u s t f u l l y a p p l y t h e b r a k e p e d a lthen press the shift lever buttonbefore you can shift from P (Park)while the ignition key is in ON/RUN.If you cannot shift out of P (Park),ease pressure on the shift lever andpush the shift lever all the way intoP(Park) as you maintain brakeapplication. Then move the shiftlever into another gear. SeeShiftingout of Park (AutomaticTr a n s m i s s i o n )0188.
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 Stuck0178.

196 Driving and Operating
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
To s e t t h e p a r k i n g b r a k e , h o l d t h ebrake pedal down and pull up on theparking brake lever. If the ignition ison, the brake system warning lightwill come on. SeeBrake SystemWarning Light011 4.
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 brake pedal down. Pull theparking brake lever up until you canpress the release button. Hold therelease button in as you move thebrake lever all the way down.
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.
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.

The speedometer reading can bedisplayed in either English or metricunits. SeeDriver Information Center(DIC)0121.Theincrementvalueused depends on the unitsdisplayed.
Passing Another Vehicle WhileUsing Cruise Control
Use the accelerator pedal toincrease the vehicle speed. Whenyou take your foot off the pedal, thevehicle slows down to the previousset cruise control speed. Whilepressing the accelerator pedal orshortly following the release tooverride cruise control, brieflymoving the thumbwheel towardSET/- will result in cruise control setto the current vehicle speed.
Using Cruise Control on Hills
How well cruise control works onhills depends on the vehicle speed,load, and the steepness of the hills.When going up steep hills, youmight have to step on theaccelerator pedal to maintain thevehicle speed. When goingdownhill, you might have to brake orshift to a lower gear to keep your
speed down. If the brake pedal isapplied, cruise control willdisengage.
Ending Cruise Control
There are four ways to end cruisecontrol:
.To d i s e n g a g e c r u i s e c o n t r o l ,step lightly on the brake pedal orclutch for manual transmission.
.Press*.
.Shift the transmission toN(Neutral).
.To t u r n o f f c r u i s e c o n t r o l ,
press5.
