yellowblue To remove the key on manual transmission vehicles, turn the key to OFF, then press the button and turn the key to LOCK. Do not hold the button in while turning the key to OFF. Pull the key straight out. 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. Retained Accessory Power (If Equipped) Your vehicle may be equipped with a Retained Accessory Power (RAP) feature which will allow certain features on your vehicle to continue to work up to 20 minutes after the ignition key is turned to OFF. 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. Key Release Button (Manual Transmission) The ignition key cannot be removed from the ignition of manual transmission vehicles unless the key release button is used. 2-16
