Function 

The ventilation prevents windows from fogging up, provides fresh air to the occupants and ensures that uniform and pleasant temperatures in the interior are reached quickly.

In normal operation, when the vehicle is stationary or to increase the air quantity, through-ventilation is achieved with the assistance of the blower motor. Fresh air is drawn in via the air inlet in the engine hood and via the fresh air/air recirculation flap (fresh air position).

Depending on setting of control and operating unit, the air is directed through the air ducts to the air vents in the interior.

In air recirculation mode, air is drawn in from the vehicle interior by the blower motor through the fresh air/air recirculation flap (recirculated air position).

When the ignition is switched off, the fresh air/air recirculation flap is automatically moved into a 50 % fresh air and 50 % recirculated air position. This achieves a significant reduction in the flap closing forces.

Air flows into the trunk through ventilation slots below the rear shelf and flows out of the vehicle again through the rear ventilation.
