Ignition Positions With the key in the ignition switch, you can turn the switch to four positions. 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. LOCK (A): This is the only position from which you can remove the key. This locks your steering wheel, ignition and automatic transaxle. Push in the ignition switch as you turn the key toward you. If you have an automatic transaxle, the ignition switch can't be turned to LOCK unless the shift lever is in PARK (P). 2-15
