With the key in the ignition switch, you can turn it to four different positions.
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.
(LOCK): This position locks your steering column. It is a theft-deterrent feature. You will only be able to remove your key when the ignition is turned to LOCK. If you have an automatic transaxle, the ignition switch cannot be turned to LOCK unless the shift lever is in PARK (P). If you have a manual transaxle, the ignition switch can be turned to LOCK in any shift lever position.Caution: If you have a manual transaxle removing the key from the ignition switch 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 to ACC.
ACC (ACCESSORY): This position operates some of your electrical accessories. It unlocks the steering wheel and ignition.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 transaxle. 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.
