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


Object Number: 810336  Size: B3

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 in all the way. If none of this works, then your vehicle needs service.

A (OFF): This is the only position from which you can remove the key. It also locks your ignition and transaxle. A warning chime will sound if you open the driver's door when the ignition is off and the key is in the ignition.

B (ACCESSORY): This position lets you use things like the radio and windshield wipers when the engine is not running. To use ACCESSORY, turn the key clockwise to the first position. Use this position if your vehicle must be pushed or towed, but never try to push-start your vehicle. See Recreational Vehicle Towing .

C (ON): This position unlocks the ignition. It is also the position to where the key returns after you start the engine and release the switch. The switch will stay in this position 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.

D (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 up to 10 minutes after the ignition is turned to OFF.

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