With the ignition key in the ignition switch, you can turn the switch 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 in which you can remove the key. This position locks your ignition and transaxle. It's a theft-deterrent feature.

ACC (Accessory): This position lets you use your electrical accessories such as power windows, power sunroof (option), radio and the windshield wipers.

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

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

Key Reminder Warning

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

Always leave your key in OFF. If you leave it in any other position, you will drain the battery power.

Retained Accessory Power (RAP)

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