The air outlet nozzles are selected via the air distribution rotary switch.
For this purpose, 12 positions of the air distribution rotary switch are available, which are arranged in the following 3 main directions.

Blower switch
The 3-stage blower switch is used to define the intensity of the air the blower motor (M2) delivers into the vehicle interior.

Rear windshield heater
The heater/AC operating unit transmits, after the heated rear window switch is pressed, a switch-on request to the SAM control unit (N10/10), which energizes the heated rear window (R1).
Simultaneously, the function LED in the heated rear window switch is switched on. If the heated rear window switch is pressed again, the actuation of the heated rear window is terminated.
