IGNITION SWITCH 2) Turn the ignition key slightly in the ON direction. 3) Turn the key toward the LOCK position. 4) Remove the key. The shift lever is designed so it cannot be moved out of P (Park) and into any of the other gear positions if the ignition key is turned to OFF or if the key is removed from the switch. The shift lever can be moved if the ignition switch is in the ACC position. This allows the vehicle to be moved if the battery is discharged. The shift lever can also be moved if the ignition switch is in the ON position and the foot brake pedal is depressed. There is an OFF position between the LOCK and ACC positions. The OFF position is indicated by a 1 on the key cylinder. When the ignition is in the OFF position, the steering wheel is not locked. In order for the steering wheel to be locked, it must be turned about 1/8 of a turn clockwise from the straight up position. To lock the steering wheel, turn the key to the LOCK position. Remove the key. To unlock the steering wheel, insert the key and turn it gently while rotating the steering wheel slightly right and left. WARNING Never remove or turn the key to the LOCK position while driving. The steering wheel will lock. This may cause the driver to lose control of the vehicle and could result in serious vehicle damage or personal injury.
