Running the Vehicle
While Parked
It is better not to park with the
engine running.
If the vehicle is left with the engine
running, follow the proper steps to
be sure the vehicle will not move.
See Shifting Into Park 0 179 and
Engine Exhaust 0 181.
If parking on a hill and pulling a
trailer, see Driving Characteristics
and Towing Tips 0 201.
Automatic
Transmission
A shift position indicator is in the
instrument cluster.
There are several different positions
for the shift lever.
See Range Selection Mode under
Manual Mode 0 185.
P : This position locks the rear
wheels. It is the best position to use
when starting the engine because
the vehicle cannot move easily.
When parked on a hill, especially
when the vehicle has a heavy load,
you might notice an increase in the
effort to shift out of P (Park). See
Torque Lock under Shifting Into
Park 0 179.
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).
