Problem: the sunroof cannot be closed and you cannot see the cause.

WARNING  
You could be severely or even fatally injured when closing the sliding sunroof with increased closing force or if the antientrapment feature is deactivated. Make sure that nobody can become trapped when closing the sliding sunroof.

If the sliding sunroof is obstructed during closing and reopens again slightly:

► Immediately after the sliding sunroof blocks, pull the switch in the overhead control panel down to the point of resistance and hold it until the sliding sunroof is closed.

The sliding sunroof is closed with increased force.

If the sliding sunroof is obstructed again during closing and reopens again slightly:

► Immediately after the sliding sunroof blocks, pull the switch in the overhead control panel down to the point of resistance and hold it until the sliding sunroof is closed.

The sliding sunroof is closed without the anti-entrapment feature.

WARNING  
Pressing and holding the sliding sunroof switch to close the sliding sunroof immediately after it had been blocked two times will cause the sliding sunroof to close without the anti-entrapment feature for as long as you hold the switch.

If the sliding sunroof still cannot be opened or closed due to a malfunction, contact a qualified specialist workshop, e.g. an authorized Mercedes-Benz Center.
