Sliding/pop-up roof, function





The sliding/pop-up roof is a combination of a sliding roof and pop-up roof. It is controlled by the motor for the sliding/pop-up roof drive assembly (M12) located on the sliding roof frame below the overhead control panel.
Two types of control are possible:
Opening/closing sliding roof (sliding roof opens toward rear)
Opening/closing pop-up roof

The sliding and pop-up roof cannot be opened simultaneously. Operation is controlled by the sliding/pop-up roof switch (S13/2) in the overhead control module.

The following functions can be controlled with the switch:
Closing sliding/pop-up roof (1 or 3); the sliding roof or pop-up roof is closed depending on which is open.
Opening sliding roof (2); if the pop-up roof is open it is closed previously.
Opening pop-up roof (4); if the sliding roof is open it is closed previously.
