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


Object Number: 806161  Size: B3
A (ACCESSORY): This position operates your electrical accessories. Press in the ignition switch as you turn it toward you.

B (LOCK): This position locks your ignition when the key is removed. The steering wheel locks with a manual transaxle. This is the only position from which you can remove the key. A warning chime will sound if you open the driver's door when the ignition is in LOCK and the key is in the ignition.

Caution: On manual transaxle vehicles, turning the key to LOCK will lock the steering column and result in a loss of ability to steer the vehicle. This could cause a collision. If you need to turn the engine off while the vehicle is moving, turn the key only to OFF. Don't press the key release button while the vehicle is moving.

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 unlocks the steering wheel (for vehicle's equipped with a manual transaxle) and ignition, but does not send power to any accessories. Use this position if your vehicle must be pushed or towed, but never try to push-start your vehicle. A warning chime will sound if you open the driver's door when the ignition is in OFF and the key is in the ignition.

D (RUN): This is the position to which the switch returns after you start your engine and release the switch. The switch stays in RUN while the engine is running. But even while 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 the engine. When the engine starts, release the key. The ignition switch will return to RUN for normal driving.

Even if the engine is not running, ACCESSORY and RUN allow you to operate electrical accessories, such as the radio.

Key Release Button (Manual Transaxle)


Object Number: 807764  Size: A2

The ignition key cannot be removed from the ignition unless the key release button is used.

To remove the key, turn the key to OFF. Then, while pressing the key release button in, turn the key to LOCK and pull it straight out.

Retained Accessory Power (RAP)

Your vehicle is equipped with a Retained Accessory Power (RAP) feature which will allow the radio to continue to work up to 10 minutes after the ignition is turned to OFF.

Your radio will work when the ignition key is in RUN or ACCESSORY. Once the key is turned from RUN to OFF, the radio will continue to work for up to 10 minutes or until the driver's door is opened.
