Use the key to turn the ignition switch to four different positions.
A (LOCK/OFF) : This position locks the ignition and transmission. It is a theft-deterrent feature. The key can only be removed when the ignition is turned to LOCK/OFF.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 (ACC/ACCESSORY) : This position lets things like the radio and the windshield wipers operate while the engine is off. Lengthy operation of features such as the radio in the ACC/ACCESSORY ignition position and the ON/RUN position may drain the battery and prevent your vehicle from starting. Do not operate your vehicle in the ACC/ACCESSORY ignition position for a long period of time.Never leave your vehicle with the keys inside, as it is an easy target for joy riders or thieves. If you leave the key in the ignition and park your vehicle, a chime will sound, when you open the driver's door. Always remember to remove your key from the ignition and take it with you. This will lock your ignition and transmission. Also, always remember to lock the doors.
The battery could be drained if you leave the key in the ignition while your vehicle is parked . You may not be able to start your vehicle after it has been parked for an extended period of time.
