Ignition Positions With the key in the ignition switch, you can turn the key to four different positions. 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 all the way in. If it is, turn the steering wheel left and right while you turn the key hard. If none of this works, then your vehicle needs service. LOCK: This position locks your steering wheel, ignition, shift lever and transaxle. This is the only position in which you can insert or remove the key. For easier key operation when unlocking the steering wheel, move the steering wheel from right to left and turn the key to ACC. ACC (Accessory): This position operates some of your electrical accessories, such as the radio, but not the climate control system. {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. Do not push the key in while the vehicle is moving. ON: This is the position to which the switch returns after you start your engine and release the key. 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 accessories, and to display some instrument panel warning lights. START: This position starts the engine. When the engine starts, release the key. The switch will return to ON for normal driving. Do not turn the key to START if the engine is running. Even if the engine is not running, ACC and ON allow you to operate electrical accessories, such as the radio. 2-18
