LOCK (B): 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. Starting Your Gasoline Engine If you have a diesel engine, see"Starting Your Diesel Engine" in the Diesel Engine Supplement. Move your shift lever to PARK (P) or NEUTRAL (N). Your engine won't start in any other position -- that's a safety feature. To restart when you're already moving, use NEUTRAL (N) only. OFF (C): 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 isoff (for example, if your vehicle is being pushed). RUN (D): This is the position for driving. START (E): This position starts your engine. NOTICE: Don't try toshift to PARK (P) if your vehicle is moving. If youdo, you could damage the transmission. Shift to PARK (P) only whenyour vehicle is stopped. 1. Without pushing the accelerator pedal, turn your ignition key to START. When the engine starts, let go of the key. The idle speed will go down as your engine gets warm. NOTICE: If your key seemsstuck in LOCK and you can't turn it, be sure you are using the correctkey; if so, is it all the way in? If it is, then turn the steering wheel leftand right while you turn the key hard. But turn the key only withyour hand. Using a tool to force it could break thekey or the ignition switch.If none of this works, then your vehicle needs service. 2-13
