Open panorama sliding roof via recirculated air button

The panorama sliding roof opening function with recirculated air button is executed only when it was previously closed with the recirculated air function.

When actuating the air recirculation switch (N22s2) am AAC [KLA] control and operating unit (N22) (except code (581) Comfort automatic air conditioning) or the air recirculation switch (N22/7s2) on the comfort AAC control and operating unit (N22/7) (with code (581) Comfort automatic air conditioning), the panoramic sliding roof is actuated in the opening direction until the previously stored position is reached.

If "Closing" via the air recirculation switch is initiated again during the "Opening" sequence before the stored position is reached, then the initially stored opening position is retained.

Interruption of sequence

Intermediate manual actuation
Blockage detection
Actuation request is rescinded
Failure of CAN message (CAN = Controller Area Network).

When the panoramic sliding roof is opened via the recirculated air switch, the windows are also opened to the previously stored position.
