Ignition Positions - Buick 2008 Lucerne Owner's Manual

Ignition Positions

With the ignition key in the ignition, the key can be
turned to four different positions:
In order to shift out of PARK (P), ignition must be in the
ON/RUN and the regular brake pedal must be applied.
Notice: Using a tool to force the key from the
ignition switch could cause damage or break the
key. Use the correct key and turn the key only with
your hand. Make sure the key is in all the way. If
none of this works, then your vehicle needs service.
A (LOCK/OFF): This is the only position in which the
ignition key can be inserted or removed. This position
locks the ignition and transmission and steering column.
It is a theft-deterrent feature.
If the steering wheel is locked, move it from right to left
and turn the key to ACC/ACCESSORY. If none of
this works, then your vehicle needs service.
B (ACC/ACCESSORY): This position lets the radio and
windshield wipers operate while the engine is off. To
use ACC/ACCESSORY, turn the key clockwise.
C (ON/RUN): This position is where the key returns to
after the vehicle is started. This position displays
some of the warning and indicator lights.
The battery could be drained if you leave the key in the
ACC/ACCESSORY or ON/RUN position with the engine
off. You may not be able to start your vehicle if the battery
is allowed to drain for an extended period of time.
D (START): This position starts the engine.
A warning chime will sound and the Driver Information
Center (DIC) will display DRIVER DOOR OPEN
when the driver's door is opened if the ignition is in
LOCK/OFF, ACC/ACCESSORY and the key is in the
ignition. See DIC Warnings and Messages on page 3-56
for more information.
