After the DEFROST function, the defrosting flap is moved with a delay into the new flap position. When the AUTO button is operated on the driver's side, the defrosting flaps are opened or closed in accordance with a curve program. The AUTO button on the passenger side has no effect on the position of the defrosting flaps program.

Virtual flap: When the AUTO button is operated on the driver's/passenger's side, the virtual flap is opened or closed individually on the left/right in accordance with a curve program. The flaps are always closed when the following criteria are satisfied: - Controlled variable Y > 90 % a n d - Heat exchanger temperature < desired ventilation temperature + correction value The opening angle of the virtual flap can be further reduced by means of different blower settings on the driver's and passenger's sides. The flap with the smaller blower share is throttled. The flap with the larger blower share remains unchanged.

Footwell flaps: When the AUTO button is operated on the driver's/passenger's side, the footwell flaps are opened or closed individually on the left/right in accordance with a curve program.
