With the key in the ignition switch, you can turn it to five different positions.


Object Number: 811569  Size: B3
(A) ACCESSORY: This position lets you use your electrical accessories such as power windows, power sunroof (if equipped), radio and the windshield wipers. To use, push in the ignition key and turn it toward you. Your steering wheel will remain locked, just as it was before you inserted the key.

(B) LOCK: This is the only position in which you can remove the key. This position locks your ignition, steering wheel and transaxle. It's a theft-deterrent feature.

Notice: If your key seems stuck in LOCK/OFF and you cannot 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 work, then your vehicle needs service.

(C) OFF: This position lets you turn off the engine but still turn the steering wheel. It doesn't lock the steering wheel like LOCK and it doesn't send any electrical power to the accessories. The instrument panel cluster will remain powered in LOCK to illuminate the gear shift indicator. The cluster will also activate the parking brake light when the parking brake is set. Use OFF if you must have your vehicle in motion while the engine is not running.

(D) RUN: This is the position the switch returns to after you start your engine and release the switch. This is also the position for normal driving. Even when the engine is not running, you can use RUN to operate your electrical accessories and to display some instrument panel warning lights.

(E) START: This position starts your engine. When the engine starts, release the key. The ignition switch will return to RUN for normal driving.

Key Reminder Warning

If you leave your key in OFF, you will hear a warning chime when you open the driver's door.

Always leave your key in LOCK while the engine is off. If you leave it in any other position, you will drain your battery power.

Retained Accessory Power (RAP)

After you turn the ignition off and remove the key, you will still have power to such accessories as the power windows, audio steering wheel controls (if equipped), clock, sunroof (if equipped) and the radio for up to 10 minutes. The instrument panel cluster lights will stay on for a few seconds, then will go out. Once you open a door, the power will shut off.
