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.

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.

Passing Another Vehicle WhileUsing Cruise Control
Use the accelerator pedal toincrease the vehicle speed. Whenyou take your foot off the pedal, thevehicle will slow down to theprevious set cruise speed. Whilepressing the accelerator pedal orshortly following the release tooverride cruise control, brieflypressing SET–will result in cruisecontrol set to the current vehiclespeed.
Using Cruise Control on Hills
How well the cruise control workson hills depends on the vehiclespeed, the load, and the steepnessof the hills. When going up steephills, pressing the accelerator pedalmay be necessary to maintainvehicle speed.
While going downhill:
.Vehicles with a 6-speedautomatic transmission and agasoline engine have CruiseGrade Braking to help maintaindriver selected speed.
Cruise Grade Braking is enabledwhen the vehicle is started andcruise control is active. It is notenabled in Range SelectionMode. It assists in maintainingdriver selected speed whendriving on downhill grades byusing the engine andtransmission to slow the vehicle.
To d i s a b l e a n d e n a b l e C r u i s eGrade Braking for the currentignition key cycle, press andhold the Tow/Haul button forfive seconds. A DIC messagedisplays. SeeTr a n s m i s s i o nMessages0157.
.Vehicles with a diesel enginehave Cruise Grade Brakingenabled when Tow/Haul Mode ison, the exhaust brake is on,or both are on.
For other forms of descent control,seeHill Descent Control (HDC)0297,Automatic Transmission0277,andTo w / H a u l M o d e0282.
Ending Cruise Control
There are four ways to end cruisecontrol:
.Step lightly on the brake pedal.
.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.

SeeEngine Compartment Overview0354for reservoir location.
When to Check Power Steering
Fluid
It is not necessary to regularlycheck power steering fluid unlessthere is a leak suspected in thesystem or an unusual noise isheard. A fluid loss in this systemcould indicate a problem. Have thesystem inspected and repaired.
Wait for the power steering systemto cool, with the engine off, beforechecking the fluid.
How to Check Power Steering
Fluid
To c h e c k t h e p o w e r s t e e r i n g f l u i d :
1. Turn the key off and let theengine compartmentcool down.
2. Wipe the cap and the top of thereservoir clean.
3. Unscrew the cap and wipe thedipstick with a clean rag.
4. Replace the cap andcompletely tighten it.
5. Remove the cap again andlook at the fluid level on thedipstick.
The level should be between theADD and FULL marks. If necessary,add only enough fluid to bring thelevel up to the hashed area betweenthe ADD and FULL marks.
What to Use
To d e t e r m i n e w h a t k i n d o f f l u i d t ouse, seeRecommended Fluids andLubricants0462.Alwaysusetheproper fluid.
Caution
Use of the incorrect fluid may
damage the vehicle and the
damages may not be covered by
the vehicle warranty. Always use
the correct fluid listed in
Recommended Fluids and
Lubricants0462.
Washer Fluid
What to Use
When windshield washer fluid needsto be added, be sure to read themanufacturer's instructions beforeuse. Use a fluid that has sufficientprotection against freezing in anarea where the temperature may fallbelow freezing.
