yellowblue LOCK (B): This is the only position in which you can remove the key. This locks your steering wheel, ignition and transaxle. OFF (C): This position unlocks the steering wheel, ignition and transaxle, but does not send electrical power to any accessories. Use this position if your vehicle must be pushed or towed, but never try to push-start your vehicle. A warning chime will sound if you open the driver's door when the ignition is off and the key is in the ignition. RUN (D): This is an on position to which the switch returns after you start your engine and release the switch. The switch stays in RUN when the engine is running. But even when the engine is not running, you can use RUN to operate your electrical power accessories, and to display some instrument panel warning lights. START (E): This position starts the engine. When the engine starts, release the key. The ignition switch will return to RUN for normal driving. Note that even if the engine is not running, ACCESSORY and RUN are positions that allow you to operate your electrical accessories, such as the radio. 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. 2-39
