By actuating the unlock button on the transmitter key (A8/1) the actuation request is received by the left front IR receiver (A26/1) and is transmitted to the left front door control unit (N69/1). It then actuates the left front power window motor (M10/3) in the "opening" direction and simultaneously relays the opening request to the left front door control unit (N69/2), left rear door control unit (N69/3) and right rear door control unit (N69/4).

The corresponding door control units then actuate the
