GM None Pontiac Aztek - Manual (Page 97)

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? If it is, then turn the
steering wheel left and right while you turn the key
hard. Turn the key only with your hand. Using a
tool to force it could break the key or the ignition
switch. If none of these works, then your vehicle
needs service.
B (ACCESSORY): This position allows you to use
things like the radio and the windshield wipers while 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.
C (ON): This is the position that the switch returns to
after you start your engine and release the key.
The switch stays in ON when the engine is running.
But even when the engine is not running, you can use
ON to operate your electrical power accessories, and to
display some instrument panel warning lights.
D (START): This position starts the engine. When the
engine starts, release the key. The ignition switch
will return to ON for normal driving.
If the engine is not running, ACCESSORY and ON are
positions that allow you to operate your electrical
accessories, such as the radio.
Retained Accessory Power (RAP)
With RAP, the power windows, the audio system, the
sunroof and the Automatic Level Control will continue to
work up to 10 minutes after the ignition key is turned
to OFF and none of the doors are opened.
