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


Object Number: 807282  Size: B3
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's 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 doesn't lock the steering wheel like LOCK. Use OFF if you must have your vehicle in motion while the engine is off (for example, if your vehicle is being pushed).

D (RUN): This is the position for driving.

E (START): This position starts your engine.

Engine Starter Over-Crank Protection

Your vehicle may have an engine starter over-crank protection system. If the starter motor overheats and shuts off due to over-cranking, the motor must cool down before it will reset and allow starter operation. It can take up to six minutes before the starter will work again.
