Ignition Positions With the ignition key in the ignition, the key can be turned to four different positions: B (ACCESSORY): This position lets the radio and windshield wipers operate while the engine is off. To use ACCESSORY, turn the key clockwise. C (RUN): This position is where the key returns to after the vehicle is started. This position displays some of the warning and indicator lights. D (START): This position starts the engine. A warning chime will sound and the Driver Information Center (DIC) will display DRIVER'S DOOR AJAR when the driver's door is opened if the ignition is in OFF, ACCESSORY and the key is in the ignition. See DIC Warnings and Messages on page 3-57 for more information. Retained Accessory Power (RAP) 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. A (OFF): This is the only position in which the ignition key can be inserted or removed. This position locks the ignition and transaxle. It is a theft-deterrent feature. If the vehicle has Retained Accessory Power (RAP), certain features will continue to operate for up to 10 minutes after the ignition key is turned to OFF unless a door is opened. 2-23
