Convenience closing function via recirculated air button
Actuation of the recirculated air button in the automatic AC pushbutton control module (N22) for t > 1 s triggers the convenience closing function. The overhead control panel control module (N70) and the door control modules (N69/1, N69/2, N69/3, N69/4) receive the signal to automatically close the sliding/pop-up roof and the power windows from the automatic AC pushbutton control module (N22) via the CAN bus. Simultaneously the momentary roof and window positions are stored in the corresponding control module. To avoid excessive loads first the sliding/pop-up roof and then the windows are automatically closed.

Convenience opening function via recirculated air button
When the recirculated air button is pressed again for t > 1 s the sliding/pop-up roof and the power windows are moved to the previously stored positions.
Exception:
If some of the windows have been opened manually while the recirculated air mode was switched on, the windows remain in the set positions after completion of the recirculated air function.



Within the scope of the convenience closing feature the roof and window positions stored when the recirculated air button was pressed, are canceled when the ignition is switched off.
