When closing the roller sunblind, make sure
that no body parts are in the sweep area.
If somebody becomes trapped:
Rrelease the switch immediately, or
Rpress the switch in any direction during the

Problems with the sliding sunroof
Your vehicle may be equipped with a sliding sunroof or a panorama roof with power tilt/sliding
panel. In the following section, the term "sliding sunroof" refers to both sliding sunroof variants.
GWARNING
If you close the sliding sunroof again immediately after it has been blocked or reset, the sliding
sunroof closes with increased or maximum force. The reversing feature is then not active. Parts
of the body could be trapped in the closing area in the process. This poses an increased risk of
injury or even fatal injury.
