Automatically moving to the last set seat position

(up to 30.5.05)

The last driving position of the driver seat, steering column and outside mirror will be set, key-related, when the transmitter key (A8/1) is inserted into the EIS control unit with the door closed. The key dependency can be switched off in the instrument cluster (A1).

When the seat is adjusted longitudinally to the rear, the backrest, longitudinal position and rear height are adjusted before the head restraint to prevent a collision between the head restraint and the headliner.

The position recognition for the seats is performed by one Hall sensor each in the adjustment motors.
