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).
