With the ignition key in the ignition, the key can be turned to five different 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.
C (OFF): In this position the engine is off. Use the OFF position if the vehicle must be pushed or towed.A warning chime will sound when the driver's door is opened if the ignition is in OFF, LOCK or ACCESSORY and the key is in the ignition.
