My car's roof will not close all the way

Welcome to 2CarPros.

Since power was removed while it was still moving, the system needs to relearn the procedure. I am going to provide directions for resetting / relearning the functions. Note that the directions will ask if you have a "consult III" That is a scanner used that chances are you don't have. If that is the case, go to number 7 in the directions and start there. Those directions are for calibration without the scanner.
