Leaving Your Vehicle With The Engine Running; Torque Lock - GMC Chevrolet SSR 2003 Owner's Manual

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 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 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
wasn't fully locked into PARK (P).

Torque Lock

If you are parking on a hill and you don't 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.
Shifting Out of Park (P)
Your vehicle has an automatic transmission shift lock
control system You have to fully apply your regular
brake before you can shift from PARK (P) when
the ignition is in RUN. See Automatic Transmission
Operation on page 2-17.
If you cannot shift out of PARK (P), ease pressure on
the shift lever, push the shift lever all the way into
PARK (P), and release the shift lever button as you
maintain brake application. Then press the shift
lever button and move the shift lever into the gear
you wish.
