Ignition Positions With the key in the ignition, you can turn to five different positions. B (LOCK): This position locks your ignition when the key is removed. The steering wheel locks with a manual transaxle. This is the only position from which you can remove the key. A warning chime will sound if you open the driver's door when the ignition is in LOCK and the key is in the ignition. {CAUTION: On manual transaxle vehicles, turning the key to LOCK 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 OFF. Don't press the key release button while the vehicle is moving. A (ACCESSORY): This position operates your electrical accessories. Press in the ignition switch as you turn it toward you. Notice: If your key seems stuck in LOCK and you can not 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. Turn the key only with your hand. Using a tool to force it could break the key or the ignition switch. If none of these works, then your vehicle needs service. 2-17
