Ignition Positions With the key in the ignition switch, you can turn the key to five different positions. B (LOCK): This position locks your ignition and transmission. It's a theft-deterrent feature. You will only be able to remove your key when the ignition is turned to LOCK. NOTICE: If your key seems stuck in LOCK and you can't turn it, be sure you are using the correct key; if so, is it all the way in? Turn the key only with your hand. Using a tool to force it could break the key or the ignition switch. If none of this works, then your vehicle needs service. C (OFF): This position lets you turn off the engine. 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. A (ACCESSORY): This position lets you use things like the radio, power windows and the windshield wipers when the engine is off. Push in the key and turn it toward you. 2-19
