Ignition Positions - Pontiac 2002 Aztek Owner's Manual

Ignition Positions

With the key in the ignition, you can turn the key to
four different positions.
A (OFF): This is the only position from which you can
remove the key. This position locks the steering wheel,
ignition and transaxle.
2-28
NOTICE:
If your key seems stuck in OFF and you can't
turn it, be sure you are using the correct key;
if so, is it all the way in? Turn the key only with
your hand. Using a tool to force it could break
the key or the ignition switch. If none of this
works, then your vehicle needs service.
B (ACCESSORY): This position allows you to use
things like the radio and the windshield wipers when the
engine is off. This position will allow you to turn off the
engine, but still turn the steering wheel. Use
ACCESSORY if you must have your vehicle in motion
while the engine is off (for example, if your vehicle is
being pushed or towed).
