Ignition Positions With the key in the ignition, you can turn it to five different positions. A (ACCESSORY): This position lets you use things like the radio and the windshield wipers and power windows (if equipped) when the engine is off. Push in the key and turn it toward you. Your steering wheel will remain locked, just as it was before you inserted the key. NOTICE: Don't operate accessories in the ACCESSORY position for long periods of time. Prolonged operation of accessories in the ACCESSORY position could drain your battery and prevent you from starting your vehicle. 2-19
