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? If it is, then turn the steering wheel left and right while you turn the key hard. But 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. OFF (C): 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). RUN (D): This is the position for driving. START (E): This position starts your engine. Key Release Button The key cannot be removed from the ignition of manual transmission vehicles unless the key release button is used. To remove the key on manual transmission vehicles, turn the key to OFF. Then turn the key to LOCK while pressing the key release button down at the same time. Pull the key straight out. On automatic transmission vehicles, turn the key to LOCK and pull it straight out. 2-20
