If the vehicle is equipped with a console shift lever, use
this procedure to shift the vehicle into P (Park):
1. Hold the brake pedal down.
2. Move the shift lever into P (Park) by pushing the
lever all the way toward the front of the vehicle and
then to the left.
3. While keeping the brake pedal applied, set the
parking brake. See Parking Brake on page 3 28
for more information.
4. Turn the ignition key to LOCK/OFF.
5. Remove the key and take it with you. If you can
leave the vehicle with the ignition key in your hand,
the vehicle is in P (Park).
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
3-30
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 your vehicle is in P (Park) and the parking
brake is firmly set before you leave it. See Parking
Brake on page 3 28 for more information.
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 Park in this section.
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).
