Function

The tilting/sliding roof is closed by actuating the air recirculation switch (N22s2) (except code (581) Comfort automatic air conditioning) or air recirculation switch (N22/7s2) (with code (581) Comfort automatic air conditioning). The position last moved to is stored. When the recirculated air mode is completed the sliding roof or power windows move back to this stored position. However, this is only accomplished, when the tilting/sliding roof is not actuated manually during the recirculated air mode.

If an opening operation is started with the recirculated air switch while closing, the SR motor reverses directions immediately. M12m1
