Function 

The panoramic sliding roof can be opened by pulling the roof system switch (N70s1) toward the rear of the vehicle to the actuation point. In this case, the overhead control panel control module (N70) reads in the status of the roof system switch (N70s1) and actuates the panoramic sliding roof motor (M12/6m1) as long as the switch is actuated or until the panoramic sliding roof is completely open.

Actuation is possible again only when the overhead control panel control module (N70) has recognized that the roof system switch (N70s1) is in the non-actuated position (switch not actuated for longer than 1 s).

Function abortion 

If the overhead control panel control module (N70) detects a lock-up, the "Open panoramic sliding roof" function is aborted.

The "Open panoramic sliding roof" function is restricted in the desynchronized state. In this case, actuation of the panoramic sliding roof motor (M12/6m1) is possible only for a maximum of 1 s. Then, it is necessary to release the roof system switch (N70s1) and press it again to actuate the roof again.
