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


Object Number: 807282  Size: B3

Notice: Lengthy operation of features such as the radio in the accessory ignition position may drain the battery and prevent your vehicle from starting. Do not operate your vehicle in the accessory ignition position for a long period of time.

A (ACCESSORY):  This position lets you use things like the radio and the windshield wipers when the engine is off. Push in the key and turn it toward you. Your steering wheel will remain locked, just as it was before you inserted the key.

Caution: On manual transmission vehicles, turning the key to LOCK will lock the steering column and result in a loss of ability to steer the vehicle. This could cause a collision. If you need to turn the engine off while the vehicle is moving, turn the key only to OFF. Do not press the key release button while the vehicle is moving.

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 (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. Use OFF if you must have your vehicle in motion while the engine is off (for example, if your vehicle is being towed).

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

E (START): This position starts your engine.

The key cannot be removed from the ignition of manual transmission vehicles unless the key release button is pressed.

To remove the key, turn the ignition switch to OFF. Then turn the key to LOCK while pressing the key release button. Pull the key straight out.
