Leaving Your Vehicle With the Engine
Running
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 transaxle 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've 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 wasn't fully locked into PARK (P).

Torque Lock
If you are parking on a hill and you don't shift your
automatic transaxle into PARK (P) properly, the weight
of the vehicle may put too much force on the parking
pawl in the transaxle. 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) on page 2-29.
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 transaxle, so you
can pull the shift lever out of PARK (P).
