Pontiac 2004 Bonneville - Manual (Page 94)

Ignition Positions
With the key in the ignition,
you can turn to four
different positions.
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.
OFF: This is the only position from which you can
remove the key. This position locks your ignition and
transaxle. It is a theft-deterrent feature.
ACC (Accessory): In this position you can operate your
electrical accessories such as power windows, sunroof (if
equipped), audio system and windshield wipers.
ON: This is the position the switch returns to after you
start your engine and release the switch. Even when
the engine is not running, you can use ON to operate
your electrical accessories and to display some
instrument panel cluster warning lights. This is the
position for driving your vehicle.
START: This position starts the engine. When the
engine starts, release the key. The ignition switch will
return to ON for normal driving.
Even if the engine is not running, ACC and ON are
positions that allow you to operate your electrical
accessories.
Key Reminder Warning
If you leave your key in OFF you will hear a warning
tone when you open the driver’s door.
