Final inspection work:
- INITIALIZE THE POWER WINDOW REGULATOR
- Check the closing action of the window glasses with a closed soft top again:
  Especially the closing windows in relation to each other (door window pane closed, close side window). If applicable, correct setting (applies to rear side window only).
- Check the closing action of the door window glasses:
  For this purpose, close the door window glasses completely using the toll closing function (starting from the bottom end position) and monitor the anti-trap mechanism of the door window glass and rear side window (reversing the window glasses).
- Check the closing action of the rear side window with the soft top open:
  Lower the rear side window completely. Lower the door window pane so that the door window pane is no longer in the insert with sealing system. Close rear side window completely. In this closing action, the rear side window must not be blocked by the door window glass.
