yellowblue ACC: This is an on position in which you can operate your electrical power accessories. With the key in this position, the automatic transmission and steering column will unlock. ON: This is the position to which the switch returns after you start the engine and release the switch. The switch stays in ON when the engine is running. But even when the engine is not running, you can use ON to operate your electrical power accessories and to display some instrument panel messages and telltales. START: 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 your electrical accessories, such as the radio. A warning tone will sound if you open the driver's door when the ignition is in OFF or ACC and the key is in the ignition. CAUTION: Removing the key from the ignition switch 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 to ACC. NOTICE: If your key seems stuck in OFF and you can't turn it, be sure you are using the correct key; if so, is it all the way in? 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. 2-22
