Automatic Transmission Operation
There are several different positions for your gear
shift lever.
PARK (P):This position locks the rear wheels.
It is the best position to use when you start the
engine because your vehicle cannot move easily.
{CAUTION:
It is dangerous to get out of your vehicle
if the shift lever is not fully in PARK (P)
with the parking brake rmly set. Your
vehicle can roll.
Do not leave your vehicle when the engine
is running unless you have to. If you have
left the engine running, the vehicle can
move suddenly. You or others could be
injured. To be sure your vehicle will not
move, even when you are on fairly level
ground, always set your parking brake
and move the shift lever to PARK (P).
SeeShifting Into Park (P) on page 119.
If you are pulling a trailer, seeTowing a
Trailer on page 339.

Parking Brake
To set the parking brake, hold the regular brake
pedal down with your foot and pull up on the
parking brake lever located between the seats.
If the ignition is on, the brake system warning light
on the instrument panel cluster will come on.
SeeBrake System Warning Light on page 186.To release the parking brake, hold the regular
brake pedal down. Pull the parking brake lever up
until you can press in the button at the end of
the lever. Hold the button in as you move
the parking brake lever all the way down.
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Verify
that the parking brake is fully released and the
brake warning light is off before driving.
If you are towing a trailer and you must park on a
hill, seeTowing a Trailer on page 339.
