Function
The air cushions of the multicontour backrest can be adjusted manually via the right rear/left rear multicontour backrest switch (S103, S104) and right front/left front multicontour backrest switch group (S108, S109) in the seat cushion frame (on the outside) of the respective seat - right rear/left rear/right front/left front. The adjustments of the air cushions assumed for the shoulder region, the lumbar support region and the seat backrest lateral support are stored in a volatile memory by the left front multicontour backrest control module (N32/15)/ and right front multicontour backrest control module (N32/16) and rear multicontour backrest control module (N32/14)
These values can be stored and called up again via the memory feature in the non-volatile memory of the relevant seat control module.

The lumbar support region of the seat is operated by the lumbar support adjustment switch (S109s3). When the cross rocker is pressed towards "+" or "-" the backrest contour changes in the lumbar support region by filling/emptying the air cushion which is currently active.
When the cross rocker of the bottom half of the switch is pressed the backrest contour in the lumbar support region is changed
sequentially. First, the lower air cushion is filled/emptied again and then the upper air cushion is filled. Only one air cushion is actuated actively in this process. This sequence starts with the air cushion which has just become active.
When the cross rocker of the top half of the switch is pressed the sequence is the same as when the bottom half of the switch is pressed, only in the reverse order.
The upper air cushion is emptied first and then the lower air cushion is filled.
