Leaving Your Vehicle With the Engine
Running (Automatic Transmission)
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 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
your vehicle with the engine running.
If you have to leave your automatic transmission vehicle
with the engine running, be sure your vehicle is in
PARK (P) and your parking brake is firmly set before
you leave it. After you have moved 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 first pulling it toward you. If you can, it means that
the shift lever was not fully locked into PARK (P).
Torque Lock (Automatic Transmission)
If you are parking on a hill and you do not shift into
PARK (P) 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 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 find out how, see
Shifting Into PARK (P) (Automatic Transmission) on
page 2-28.
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).
