Leaving the Vehicle With the Engine
Running
{
WARNING:
It can be dangerous to leave the vehicle with the
engine running. The vehicle could move suddenly
if the shift lever is not fully in P (Park) with the
parking brake firmly set. And, if you leave the
vehicle with the engine running, it could overheat
and even catch fire. You or others could be
injured. Do not leave the vehicle with the engine
running.
If you have to leave the vehicle with the engine running,
be sure the vehicle is in P (Park) and the parking brake
is firmly set before you leave it. After you move the shift
lever into P (Park), hold the regular brake pedal down.
Then, see if you can move the shift lever away from
P (Park) without first pulling it toward you. If you can, it
means that the shift lever was not fully locked into
P (Park).
Torque Lock
If you are parking on a hill and you do not shift the
vehicle into P (Park) properly, the weight of the vehicle
may put too much force on the parking pawl in the
transmission. You may find it difficult to pull the shift
lever out of P (Park). This is called torque lock. To
prevent torque lock, set the parking brake and then shift
into P (Park) properly before you leave the driver seat.
To find out how, see Shifting Into Park on page 339.
When you are ready to drive, move the shift lever out of
P (Park) 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 P (Park).
Shifting Out of Park
The vehicle has an automatic transmission shift lock
control system. You have to fully apply the brakes
before you can shift from P (Park) when the ignition is in
ON/RUN. See Automatic Transmission Operation (Six
Speed Automatic Transmission)
on page 329
or
Automatic Transmission Operation (Four Speed
Automatic Transmission) on page 334.
