The function statuses are indicated by three, blue LEDs. The two groups of motors for seat ventilation are actuated by the left front seat adjustment control module with memory (N32/1), the right front seat adjustment control module (N32/2), the

left front seat ventilation blower regulator (N29/6) and the right front seat ventilation blower regulator (N29/5).

The seat ventilation at the driver's side consists of:

^ Left front seat backrest ventilation motor group (M18/10)

Each of these motor groups consists of 4 blower motors.

The seat ventilation at the passenger side consists of:
^ Right front seat cushion ventilation motor group (M18/11)
