Function 

The seat ventilation integrated in the driver seat and in the front passenger seat make it possible to ventilate the seat cushion and the backrest in two ventilation stages.

The seat ventilation is actuated by using the left front HS/seat ventilation switch (N72/1s28) and the right front HS/seat ventilation switch (N72/1s29) in the upper control panel control unit (N72/1). The left front seat cushion ventilation motor group (M18/9) and the left front seat backrest ventilation motor group (M18/10) are actuated by operating the left front HS [SIH]/seat ventilation switch (N72/1s28) via the left front seat ventilation blower regulator (N29/5), or the right front seat cushion ventilation motor group (M18/11) and the right front seat backrest ventilation motor group (M18/12) are actuated by operating the right front HS [SIH]/seat ventilation switch (N72/1s29) via the right front seat ventilation blower regulator (N29/6).

The function conditions are indicated via the two illuminated blue LEDs in the left front HS [SIH]/seat ventilation switch (N72/1s28) or in the right front HS [SIH]/seat ventilation switch (N72/1s29).

During comfort opening with the transmitter key (infrared signal), the seat ventilation of the driver seat is switched on in stage 2 for 5 min.
