Ignition Positions - Chevrolet 2005 Impala Owner's Manual

Ignition Positions

With the ignition key in the ignition, the key can be
turned to four different positions:
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 (OFF): This is the only position in which the ignition
key can be inserted or removed. This position locks
the ignition and transaxle. It is a theft-deterrent feature.
B (ACCESSORY): This position lets the radio and
windshield wipers operate while the engine is off. To use
ACCESSORY, turn the key clockwise.
C (RUN): This position is where the key returns to after
the vehicle is started. This position displays some of
the warning and indicator lights.
D (START): This position starts the engine.
A warning chime will sound and the Driver Information
Center (DIC) will display a warning message when
the driver's door is opened if the ignition is in OFF,
ACCESSORY and the key is in the ignition. See DIC
Warnings and Messages on page 3-45 for more
information.
