There are the following functions for opening and closing:

Opening and closing
- Manual closing or opening
  Press back the slide/tilt sunroof switch up to the first resistance point (for opening) or press forward (for closing).
  
  The glass slide/tilt sunroof moves also long as the switch is kept pressed.
  
  On opening, the slide/tilt sunroof (both glass sunroofs) is raised automatically. As the process continues, the rear glass sunroof closes. Subsequently, the front glass sunroof is now also raised at the front anchorage point. This enables the front glass sunroof to be shifted above the rear glass sunroof.
- Automatic closing or opening
  Press the slide/tilt sunroof switch forwards beyond the first resistance point up to the mechanical limit position (for closing) or press towards the rear (for opening). If the slide/tilt sunroof switch is pressed again, the automatic movement is halted.

NOTE: The "Open" or "Close" operation of the slide/tilt sunroof is interrupted when the "Lift" position is reached.

If the "Lift" position during automatic opening or closing of the slide/tilt sunroof is reached, the "Open" or "Close" operation is interrupted. To continue the operation, the slide/tilt sunroof switch must be pressed again - beyond the first resistance point.

NOTE: No automatic closing is possible on failure of the anti-trapping mechanism.

In the event of failure of the anti-trapping mechanism (e.g. defective Hall sensor), no automatic closing is possible. Closing is only possible with the mechanical emergency actuating unit.

Possible defect data is stored in the SHD control module.
