ACC (ACCESSORY) (B): In this position, you can operate some of your electrical power accessories (such as the radio, but not the ventilation fan). It unlocks the steering wheel and ignition. To move the key from ACC to LOCK, push in the key and then turn it to LOCK. ON (C): The switch returns to this position after you start your engine and release the switch. The switch stays in the ON position when the engine is running. But even when the ignition is not running, you can use ON to operate your electrical power accessories (including the ventilation fan) and to display some warning and indicator lights. START (D): This position starts the engine. When the engine starts, release the key. The ignition switch will return to ON for normal driving. When the engine is not running, ACC and ON allow you to operate some of your electrical accessories. A warning tone will sound if you open the driver's door when the ignition is in ACC or LOCK and the key is in the ignition. CAUTION: On manual transaxle vehicles, turning the key to LOCK and removing it will lock the steering column and result in a loss of ability to steer the vehicle. This could cause a collision. If you need to turn the engine off while the vehicle is moving, turn the key only to ACC. Don't push the key in while the vehicle is moving. 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. 2-12
