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


Object Number: 986908  Size: A2
A (LOCK and ACCESSORY): This is the only position from which you can insert or remove the key. When the key is inserted and is in this position, all accessories, electrical systems, and engine are off. If the key is cycled back to this position the accessories will remain on until the key is removed. Once the key is removed the accessories will turn off. If the key is left inserted in this position, a chime will sound when the driver's door is opened to remind you the key has been left in the ignition. If the key is left in the ignition, it can drain the battery. Make sure to remove the key when leaving the vehicle. The key can only be turned to this position if the vehicle's automatic transmission is in PARK (P). To help guard against theft, your vehicle's engine is automatically disabled shortly after turning the key to this position. This is indicated by the flashing padlock symbol on the bottom left corner of the instrument panel. The steering column is automatically locked when the key is removed. To release the steering wheel, insert the key again and turn it towards the front of the vehicle.

Notice: Using a tool to force the key from the ignition switch could cause damage or break the key. Use the correct key and turn the key only with your hand. Make sure the key is all the way in. If it is, turn the steering wheel left and right while you turn the key hard. If none of this works, then your vehicle needs service.

B (ON and ACCESSORY): This position is where the key returns to after you start your engine and release the key. The ignition switch stays in ON when the engine is running. But even when the engine is not running, you can use ON to operate your electrical accessories and to display some instrument panel warning lights.

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

Retained Accessory Power (RAP)

Your vehicle is equipped with a Retained Accessory Power (RAP) feature which will allow the radio to continue to work for one hour after the ignition is turned to OFF. The windows will also be accessible for 15 minutes or until either door is opened.
