Function
The roller sun blinds can be opened and closed via the roof system switch on the overhead control panel control unit.
The opening and closing signal is read in by the overhead control panel control unit and then actuates the roller sun blind drive unit.
The front and rear blinds can only be opened synchronously. The roller sun blinds can only be closed when the panoramic sliding roof is closed.
When opening and closing manually, the roller sun blinds are opened or closed as long as the roof system switch on the overhead control panel control
unit is held in the corresponding position.
When the roof system switch is actuated beyond the pressure point, the roller sun blinds can be opened completely and automatically.
