B (LOCK): This is the only position in which you can insert or remove the key. This position locks the ignition, steering wheel and transaxle. It's a theft-deterrent feature. D (RUN): This position is where the key returns to after you start your vehicle. With the engine off, you can use RUN to display some of your warning and indicator lights. E (START): This position starts your engine. A warning chime will sound if you open the driver's door when the ignition is in OFF, LOCK or ACCESSORY and the key is in the ignition. 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. 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 but still turn the steering wheel. It doesn't lock the steering wheel. Use OFF if you must have your vehicle pushed or towed. Retained Accessory Power (RAP) (If Equipped) With Retained Accessory Power (RAP), your power windows, audio system and sunroof (if equipped) will continue to work for up to 10 minutes after the ignition key is turned to OFF and before any of the doors are opened. 2-25
