"For non panoramic sunroof, after sunroof raises to the lift position, hold button for another 20 secs and until the sunroof "jiggles" at the open position, release switch for a maximum of 5 secs, then hold down the switch in the raising position until the sunroof has returned to the closed position after a complete opening movement. Release the switch"

I think this is the correct way. I'll try it and be back to you. Thanks pal
