Leaving Your Vehicle With the Engine
Running (Automatic Transaxle)
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
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 pushing the button.
If you can, it means that the shift lever was not
fully locked into PARK (P).
Torque Lock (Automatic Transaxle)
If you are parking on a hill and you do not 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)" previously in the 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 parking pawl in the
transaxle, so you can pull the shift lever out of
PARK (P).
