Function 

The ventilation system ensures:

Ventilation is achieved with the assistance of the blower motor (M2) during normal operation, when vehicle is stationary or to increase the air quantity.

Fresh air is drawn into the heater housing via the air inlet. Depending on the control module setting, the air is directed through the air ducts to the air vents in the interior.

The air flows out of the vehicle again through the rear vent via ventilation slots to the left and right in the area below the rear side windows.

In recirculating air mode, air is drawn out of the interior of the vehicle through the recirculating air flap by the blower motor (M2), and passed to the heater housing.
