Driving and Operating A (LOCK/OFF): This is the only position from which the key can be removed. This locks the steering wheel, ignition and automatic transmission. On vehicles with an automatic transmission, the shift lever must be in P (Park) to turn the ignition switch to the LOCK/OFF position. The ignition switch can bind in the LOCK/OFF position with the wheels turned off center. If this happens, move the steering wheel from right to left while turning the key to ACC/ ACCESSORY. If this does not work, then the vehicle needs service. B (ACC/ACCESSORY): This position provides power to some of the electrical accessories. It unlocks the steering wheel and ignition. The transmission is also unlocked in this position on automatic transmission vehicles. To move the key from ACC/ACCESSORY to LOCK/OFF, push in the key and then turn it to LOCK/OFF. C (ON/RUN): The ignition switch stays in this position when the engine is running. This position can be used to operate the electrical accessories, including the ventilation fan and 12 volt power outlet, as well as to display some warning and indicator lights. The battery could be drained if the key is left in the ACC/ACCESSORY or ON/RUN position with the engine off. The vehicle might not start if the battery is allowed to drain for an extended period of time. D (START): This position starts the engine. When the engine starts, release the key. The ignition switch will return to ON/RUN for normal driving. A warning tone sounds when the driver door is opened if the ignition is still in ACC/ACCESSORY and the key is in the ignition. 8-29 Retained Accessory Power (RAP) These vehicle accessories can be used for up to 10 minutes after the engine is turned off: ...
