OCCUPANT RESTRAINT SYSTEMS When the registration is completed, one beep sounds. If the key has already been registered, the previous memory will be erased. If the same driving position profile for the same key is registered in another button, that memory will also be erased. REAR SEAT POSITION MEMORY SYSTEM A microcomputer will memorize the position of the rear seats and the height of the rear head restraints. Recording the rear seat position in the computer's memory can only be done when the ignition switch is in the "ON" position. CAUTION Do not push the "LOCK" button any longer than 2 or 3 seconds. Pushing the button longer activates an alarm. For details, see page 40.
