Resetting
Reset the sliding sunroof if it does not move smoothly.
Turn the SmartKey to position 2 in the
ignition lock.
Raise the sliding sunroof fully at the rear.
Keep the 
switch pressed for
another
second.
Make sure that the sliding sunroof can be
fully opened and closed again.
If this is not the case, repeat the steps
above again.
If the sliding sunroof still cannot be
opened or closed fully after resetting,
contact a qualified specialist workshop.
