Leaving Your Vehicle With the Engine
Running
{CAUTION:
It can be dangerous to leave your vehicle with
the engine running. Your vehicle could move
suddenly if the shift lever is not fully in
PARK (P) with the parking brake rmly set.
And, if you leave the vehicle with the engine
running, it could overheat and even catch re.
You or others could be injured. Do not leave
your vehicle with the engine running.
If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P) and the
parking brake is rmly set before you leave it. After you
move the shift lever into PARK (P), hold the regular
brake pedal down. Then, see if you can move the shift
lever away from PARK (P) without rst pulling it
toward you. If you can, it means that the shift lever was
not fully locked into PARK (P).
Torque Lock
If you are parking on a hill and you do not shift your
vehicle into PARK (P) properly, the weight of the vehicle
may put too much force on the parking pawl in the
transmission. You may nd it difficult to pull the shift
lever out of PARK (P). This is called torque lock.
To prevent torque lock, set the parking brake and then
shift into PARK (P) properly before you leave the
driver’s seat. To nd out how, seeShifting Into Park (P)
on page 2-35.
When you are ready to drive, move the shift lever out of
PARK (P) before you release the parking brake.
If torque lock does occur, you may need to have another
vehicle push yours a little uphill to take some of the
pressure from the parking pawl in the transmission, so
you can pull the shift lever out of PARK (P).
Shifting Out of Park (P)
Your vehicle has an automatic transmission shift lock
control system. You have to fully apply the regular
brakes before you can shift from PARK (P) when the
ignition is in RUN. SeeAutomatic Transmission
Operation on page 2-27.

Reducing Speed While Using
Cruise Control

Press in the button at the end of the lever until you
reach the lower speed you want, then release it.
To slow down in very small amounts, briey press
the set button. Each time you do this, you’ll go
about 1 mph (1.6 km/h) slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase your speed.
When you take your foot off the pedal, your vehicle will
slow down to the cruise control speed you set earlier.
Using Cruise Control on Hills
How well your cruise control will work on hills depends
upon your speed, load and the steepness of the
hills. When going up steep hills, you may want to step
on the accelerator pedal to maintain your speed.
When going downhill, you may have to brake or shift to
a lower gear to keep your speed down. Of course,
applying the brake takes you out of cruise control. Many
drivers nd this to be too much trouble and don’t use
cruise control on steep hills.
Ending Cruise Control
There are four ways to turn off the cruise control:
Step lightly on the brake pedal,
move the cruise control switch to off, or
shift the transmission to NEUTRAL (N).
If road conditions cause the traction control system
to activate, cruise control will turn off. SeeTraction
Control System (TCS) on page 4-9.
If the accelerator pedal is held for 60 seconds or
longer, cruise control will turn off.
Erasing Speed Memory
When you turn off the cruise control or the ignition, your
cruise control set speed memory is erased.
