Torque Lock (Automatic Transmission)
If you are parking on a hill and you do not shift your
transmission into P (Park) 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 P (Park). This is called “torque lock.”
To prevent torque lock, set the parking brake and
then shift into P (Park) properly before you leave the
driver seat. To find out how, see Shifting Into Park
(Automatic Transmission) on page 2-29.
When you are ready to drive, move the shift lever out
of P (Park) 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
transmission, so you can pull the shift lever out
of P (Park).
Shifting Out of Park
Vehicles with an automatic transmission have a shift
interlock system. You have to apply the brake pedal
before you can shift from P (Park) when the ignition is
in the ON/RUN position. See Automatic Transmission
Operation on page 2-22.
If you cannot shift out of P (Park) while holding the
brake pedal down, try this:
1. Set the parking brake.
2. Turn the ignition off and remove the key.
3. Remove the hole cover from the shift lock slot by
prying it off using a small, flat object. The shift
lock release slot is located at the top of the
shift lever.
