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


Object Number: 1839828  Size: A3
A (ACCESSORY): This position allows you to use things like the radio, power windows and the windshield wipers when the engine is off. To get into ACCESSORY, push in the key and turn it toward you. Your steering wheel will remain locked, just as it was before you inserted the key.

B (LOCK): This position locks your ignition, steering wheel and transmission. It is a theft-deterrent feature. You will only be able to remove your key when the ignition is turned to LOCK.

C (OFF): This position lets you turn off the engine but still turn the steering wheel. It does not lock the steering wheel like LOCK. Use OFF if you must have your vehicle in motion while the engine is off.

D (RUN): This is the position for driving. The battery could be drained if you leave the key in the ACCESSORY or RUN position with the engine off. You may not be able to start your vehicle if the battery is allowed to drain for an extended period of time.

E (START): This position starts your engine.

Key In the Ignition

Never leave your vehicle with the keys inside, as it is an easy target for joy riders or thieves. If you leave the key in the ignition and park your vehicle, a chime will sound, when you open the driver's door. Always remember to remove your key from the ignition and take it with you. This will lock your ignition and transaxle. Also, always remember to lock the doors.

The battery could be drained if you leave the key in the ignition while your vehicle is parked . You may not be able to start your vehicle after it has been parked for an extended period of time.
