Operation

Opening sliding/pop-up roof with recirculated air button

The sliding/pop-up roof opening function with recirculated air button is executed only when it was previously closed with the recirculated air function.

When the recirculated air button (N22s2) on the AC pushbutton control module (N22) is actuated the sliding/pop-up roof is actuated in the opening direction until the previously stored position is reached.

If closing via the recirculating air button is initiated again while opening, but before reaching the stored position, the opening position initially stored will be retained in memory.

The function is interrupted in the case of

 intermediate manual actuation

 detection of an obstruction

 reaching the stored position

 rescinding actuation request,

 CAN message not present

 When the sliding/pop-up roof is opened via recirculated air button the windows are also opened in the previously stored position.
