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


Object Number: 806855  Size: B3

Notice: If your key seems stuck in OFF and you can't turn it, be sure you are using the correct key; if so, is it all the way in? If it is, then turn the steering wheel left and right while you turn the key hard. Turn the key only with your hand. Using a tool to force it could break the key or the ignition switch. If none of these works, then your vehicle needs service.

A (OFF): This is the only position in which you can insert or remove the key. This position locks the ignition, steering wheel and transmission. It's a theft-deterrent feature.

B (ACCESSORY): This position allows you to use things like the radio and the windshield wipers when the engine is off. This position will allow you to turn off the engine, but still turn the steering wheel.

C (ON): This position is for driving. If your vehicle has an automatic transmission and you turn off the engine, the transmission will lock. If you need to shift the transmission out of PARK (P), the ignition key has to be in ON.

D (START): This position starts the engine.
