Leaving the Vehicle With the Engine
Running
{ WARNING:
It can be dangerous to leave the vehicle with the
engine running. The vehicle could move suddenly
if the shift lever is not fully in P (Park) 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 the vehicle with the engine
running.
If you have to leave the vehicle with the engine running,
be sure the vehicle is in P (Park) and the parking
brake is firmly set before leaving it. After moving the
shift lever into P (Park), hold the brake pedal down.
Then, see if you can move the shift lever away
from P (Park) without first pushing the shift lever button.
If you can, the shift lever was not fully locked in
P (Park).
Torque Lock
Torque lock is when the weight of the vehicle puts too
much force on the parking pawl in the transmission. This
happens when parking on a hill and shifting the
transmission into P (Park) is not done properly and then
it is difficult to shift out of P (Park). To prevent torque
lock, set the parking brake and then shift into P (Park).
To find out how, see “Shifting Into P (Park)” listed
previously.
If torque lock does occur, your vehicle may need to be
pushed uphill by another vehicle to relieve the parking
pawl pressure, so you can shift out of P (Park).
