The steering can bind with the wheel turned off center.
If this happens, move it from right to left while turning
the key to ACC/ACCESSORY. If this does not work,
then the vehicle needs service.

WARNING:
If you have a manual transmission removing the
key from the ignition switch will lock the steering
column and result in a loss of ability to steer the
vehicle. This could cause a collision. If you need
to turn the engine off while the vehicle is moving,
turn the key to ACC/ACCESSORY.
ACC (ACC/ACCESSORY): This position operates
some of the electrical accessories. It unlocks the
steering wheel and ignition.
3-24
(ON/RUN): This is the position in which you can
operate the electrical accessories and to display some
instrument panel cluster warning and indicator lights.
The switch stays in this position when the engine is
running.
If you leave the key in the ACC/ACCESSORY or
ON/RUN position with the engine off, the battery could
be drained. You may not be able to start the vehicle if
the battery is allowed to drain for an extended period
of time.
(START): This position starts the engine. When the
engine starts, release the key. The ignition switch will
return to ON/RUN for driving.
A warning tone will sound when the driver door is
opened, the ignition is in LOCK/OFF or ACC/
ACCESSORY and the key is in the ignition.
