Height limit setting memorized by GPS location, similar to the way HomeLink works. If at home in a low garage it would be set to be limited, elsewhere it might open to the full height.
The rear liftgate currently has the option to set and remember the desired lift-gate height. This is ideal for garages with low clearance space.
