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. Retained Accessory Power (RAP) Your vehicle is equipped with a Retained Accessory Power (RAP) feature which will allow certain features on your vehicle to continue to work for up to 20 minutes after the ignition key is turned to OFF. The RAP feature will also work with the key removed from the ignition. Your radio, power windows and overhead console will work when the ignition key is in RUN or ACCESSORY. Once the key is turned from RUN to OFF, these features will continue to work for up to 20 minutes or until a door is opened. 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. 2-28
