The key can be turned to one of three positions while in the ignition switch.
A (LOCK): This is the only position from which you can insert or remove the key. When the key is inserted and is in this position, the radio, wipers, and accessory power outlet will continue to work until the key is removed. Once the key is removed these accessories will turn off. By selecting the ON switch on the radio these accessories will continue to work for one hour or until either door is opened. If the key is left inserted in this position, a chime will sound when the driver's door is opened to remind you the key has been left in the ignition. If the key is left in the ignition, it can drain the battery. Make sure to remove the key when leaving the vehicle. The key can only be turned to this position if the vehicle's automatic transmission is in PARK (P). To help guard against theft, your vehicle's engine is automatically disabled shortly after turning the key to this position. A flashing padlock symbol on the bottom left corner of the instrument panel indicates this. The steering column is automatically locked when the key is removed. To release the steering wheel, insert the key again and turn it towards the front of the vehicle.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.
B (ON): This position is where the key returns to after you start your engine and release the key. The ignition 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.
