Function
Opening tilting/sliding roof with recirculated air button
The tilting/sliding roof opening function with recirculated air button is executed only when it was previously closed with the recirculated air function.
When the recirculated air switch (N22s2) on the AAC [KLA] control and operating unit (N22) or the air recirculation switch (N22/7s2) on the comfort AAC control and operating unit (N22/7) is actuated, the adjustment request is transmitted via interior CAN (CAN B) to the overhead control panel control unit (N70), which actuates the SR motor (M12m1) in the opening direction until the previously stored position is reached.
If, during opening, before reaching the stored position, a closing operation is started with the air recirculation switch (N22s2) on the AAC [KLA] control and operating unit (N22) or air recirculation switch (N22/7s2) on the comfort AAC control and operating unit (N22/7), reversing is started immediately.

Abortion of function
^ during intermediate manual actuation
^ lock-up recognized by overhead control panel control unit (N70)
^ the stored position is reached,
^ Actuation request is rescinded
^ Failure of message via interior CAN (CAN B)

When the tilting/sliding roof is opened with the recirculated air control, the windows are also opened in the previously stored position.
