Seat ventilation 

Active ventilation of the seat cushion and backrest is possible with three stages  using the seat ventilation integrated in the left/right seat.

The seat ventilation is operated using the seat ventilation switch (S91/2s17) and the seat ventilation switch (S92/2s17)  , which are read in by the left door control module (N69/1) and the right door control module (N69/2)  . 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:

Each of these motor groups consists of 4 blower motors.

The seat ventilation at the passenger side consists of:

Each of these motor groups consists of 4 blower motors. 

Integrated timer control 

Seat ventilation timer control is integrated in the left front seat adjustment control module with memory (N32/1) and the right front seat adjustment control module with memory (N32/2). 

This timer gradually switches the ventilation back to stage one  within a preset time. The ventilation can be manually switched off of the stage changed at any time using the controls.

IMPORTANT During convenience opening  using the transmitter key (A8/1)  , for a period of 5 min.  . the driver's seat ventilation  is switched on at stage III.
