regular brake pedal down. Then,
see if you can move the shift lever
away from P (Park) without first
pulling it toward you. If you can, the
shift lever was not fully locked into
P (Park).
Torque Lock (Automatic
Transmission)
If you are parking on a hill and you
do not shift the 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)”
in this section.
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
(Automatic Transmission)
The vehicle has an automatic
transmission shift lock control
system. You have to fully apply the
brake pedal before you can shift
from P (Park) when the ignition is
ON/RUN. See Automatic
Transmission on page 9‑31.
The shift lock control system is
designed to do the following:
. Prevent the ignition key from
being removed unless the shift
lever is in P (Park).
. Prevent movement of the shift
lever out of P (Park), unless the
ignition is in ON/RUN and the
brake pedal is applied.
The shift lock control system is
always functional except in the case
of a dead battery or low voltage
(less than 9 V) battery.
If the vehicle has an uncharged
battery or a battery with low voltage,
try charging or jump starting the
battery. See Jump Starting on
page 10‑81 for more information.
