Abstract

The vehicle seat and the steering wheel are shifted to the drive position when the door is open and to the getting in/out position when the door is opened, as long as the ignition key is inserted into the key cylinder without shifting the key at the accessory and ignition positions. Further, the seat and wheel are shifted to the drive position when the key is inserted into the key cylinder and to the getting in/out position when the key is removed therefrom, as long as the key is not shifted at the accessory and ignition positions. Further, the seat and wheel are shifted to the drive position when the key is shifted to the ignition position, as long as the key is inserted into the key cylinder and shifted at the accessory position. Furthermore, the seat and wheel are shifted to the drive position under door-closed condition and to the getting in/out position under door-open condition, when the key is shifted from the accessory position to the lock position, as long as the key is inserted into the key cylinder and not shifted at the ignition position.
