No Stop Region - Front Sliding Glass Panel
WARNING: This page is about a different car, the 2020 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
Manual closing or one touch closing of the roof opening panel cannot be stopped in a small range very close to the fully closed position. This feature is to make sure that the occupant does not leave the roof opening panel in this position because it looks fully closed allowing water intrusion.
