How to Synchronize the Windows on a Mercedes

1. Close all of the doors of the Mercedes and turn the SmartKey to the first click in the ignition cylinder.
2. Pull on the door window switch that controls the window that either reopened or did not close at all. Pull the switch until the window is closed and then hold the switch for one second. Check that all of the windows are closed properly.
3. Pull the switch again if the side window reopens a crack. Hold the switch for one second again after the window closes. Repeat the automatic locking sequence again and verify that all of the windows have closed properly and have not reopened.
