With the ignition key in the ignition switch, you can turn
the switch to five different positions.
ACCESSORY (A): This position lets you use things
like the radio and the windshield wipers when the
engine is off. To get into ACCESSORY, push in the key
and turn it toward you. The steering wheel will remain
locked, just as it was before you inserted the key.
LOCK (B): Before you put the key in, the ignition will
be in LOCK. This is the only position in which you can
remove the key. This position locks the ignition, steering
wheel and transaxle. It's a theft
NOTICE:
If your key seems stuck in LOCK 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. But 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.

deterrent feature.
OFF (C): This position lets you turn off the engine but
still turn the steering wheel. It doesn't lock the steering
wheel like LOCK does. Use OFF if you must have your
vehicle in motion while the engine is off (for example, if
your vehicle is being pushed).
RUN (D): This position is for driving.
START (E): This position starts the engine.
Retained Accessory Power (RAP)
The following accessories on your vehicle may be used
for up to 10 minutes after the ignition key is turned from
RUN to OFF:
D
Radio
D
Power Windows
D
Sunroof
Power to these accessories stops after 10 minutes or
if any door is opened. If you want power for another
10 minutes, turn the ignition key to RUN, then back
to OFF, then to LOCK. Always leave your key in
LOCK when using RAP. If you leave your key in
any other position than LOCK, your battery will
discharge prematurely.
