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 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 down the
regular brake pedal. 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 your
transmission 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)" listed
previously in this section.
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 transmission parking pawl, so you
can pull the shift lever out of PARK (P).
