Ignition Positions
With the ignition key in the ignition switch, you can turn
the switch to five positions:
ACC (A): This position lets you use things like the
radio and windshield wipers when the engine is off. To
use ACC, push in the key and turn it toward you. Your
steering wheel will stay locked.
LOCK ( B ) : Before you put the key into the ignition
switch, the switch is in LOCK. It's also the only position
in which you can remove your key. This position locks
your ignition, steering wheel and transaxle. It's a
theft-deterrent feature.
