8-18 Driving and Operating
Ignition Positions (Key
Access)
The ignition switch has four different
positions.
Notice: Using a tool to force the
key to turn in the ignition could
cause damage to the switch or
break the key. Use the correct
key, make sure it is all the way in,
and turn it only with your hand.
If the key cannot be turned by
hand, see your dealer/retailer.
To shift out of P (Park), turn the
ignition to ON/RUN and apply the
brake pedal.
A (LOCK/OFF): This is the only
position from which the key can be
removed. This locks the ignition and
automatic transmission.
The shift lever must be in P (Park)
to turn the ignition switch to the
LOCK/OFF position.
The ignition switch can bind in the
LOCK/OFF position with the wheels
turned off center. If this happens,
move the steering wheel from right
to left while turning the key to
ACC/ACCESSORY. If this does not
work, then the vehicle needs
service.
B (ACC/ACCESSORY): This
position provides power to some of
the electrical accessories. It unlocks
the ignition. The transmission is also
unlocked in this position on
automatic transmission vehicles. To
move the key from ACC/
ACCESSORY to LOCK/OFF, the
shift lever must be in P (Park).
C (ON/RUN): The ignition switch
stays in this position when the
engine is running. This position can
be used to operate the electrical
accessories, including the
ventilation fan and 12 volt power
outlet, as well as to display some
warning and indicator lights.
The battery could be drained if the
key is left in the ACC/ACCESSORY
or ON/RUN position with the engine
off. The vehicle might not restart if
the battery is allowed to drain for an
extended period of time.
D (START): This position starts the
engine. When the engine starts,
release the key. The ignition switch
will return to ON/RUN for normal
driving.
A warning tone sounds when the
driver door is opened when the
ignition is still in ACC/ACCESSORY
and the key is in the ignition.
