With the key in the ignition switch, you can turn the switch to four positions.
Notice: If your key seems stuck in LOCK/OFF and you cannot 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 work, then your vehicle needs service.
ACC (Accessory): This is the position in which you can operate your electrical accessories. With the key in this position, the ignition and automatic transaxle will unlock. Use this position if your vehicle must be pushed or towed.
