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.

Hill Start Assist (HSA)
This vehicle has a Hill Start Assist(HSA) feature, which may be usefulwhen the vehicle is stopped on agrade sufficient enough to activateHSA. This feature is designed toprevent the vehicle from rolling,either forward or rearward, duringvehicle drive off. After the drivercompletely stops and holds thevehicle in a complete standstill on agrade, HSA will be automaticallyactivated. During the transitionperiod between when the driverreleases the brake pedal and startsto accelerate to drive off on a grade,HSA holds the braking pressure foramaximumoftwosecondstoensure that there is no rolling. Thebrakes will automatically releasewhen the accelerator pedal isapplied within the two-secondwindow. It will not activate if thevehicle is in a drive gear and facingdownhill, or if the vehicle is facinguphill and in R (Reverse).
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 slipand assist the driver in maintainingcontrol, especially on slippery roadconditions.
TCS activates if it senses that anyof the drive 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 the
vehicle wheel brakes to assist thedriver in keeping the vehicle on theintended path.
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 Stuck0178and“Turning the Systems Off andOn”later in this section.
