If you had searched the forum you would have found your answer... Never the less, you got your answer!!
You can do two windows at a time (front/rear) and also same for the roof! After opening them atleast halfway, close them holding switches closed a few seconds (5 or so) then they should be set! And same for the roof... I know I'm repeating what others had already suggested but just to assure you that's the way to do it!!
