Ignition Positions With the ignition key in the ignition, the key can be turned to four different positions: A (LOCK/OFF): This is the only position in which the ignition key can be inserted or removed. This position locks the ignition and transmission and steering column. It is a theft-deterrent feature. If the steering wheel is locked, move it from right to left and turn the key to ACC/ACCESSORY. If none of this works, then your vehicle needs service. B (ACC/ACCESSORY): This position lets the radio and windshield wipers operate while the engine is off. To use ACC/ACCESSORY, turn the key clockwise. C (ON/RUN): This position is where the key returns to after the vehicle is started. This position displays some of the warning and indicator lights. In order to shift out of PARK (P), ignition must be in the ON/RUN or ACC/ACCESSORY and the regular brake pedal must be applied. Notice: Using a tool to force the key from the ignition switch could cause damage or break the key. Use the correct key and turn the key only with your hand. Make sure the key is in all the way. If none of this works, then your vehicle needs service. The battery could be drained if you leave the key in the ACC/ACCESSORY or ON/RUN position with the engine off. You may not be able to start your vehicle if the battery is allowed to drain for an extended period of time. D (START): This position starts the engine. A warning chime will sound and the Driver Information Center (DIC) will display DRIVER DOOR OPEN when the driver's door is opened if the ignition is in LOCK/OFF, ACC/ACCESSORY and the key is in the ignition. See DIC Warnings and Messages on page 3-73 for more information. 2-23
