Allion 260;driver side Glass dislocated

Hi, I am using a Toyota Allion 260, A Japanese Domestic Model. It's onky 3K km done. Y'day I rolled down all glasses when I get in to remove the heat. then I rolled up all. But the glass at Driver's side went all the way up dis-locating the groove. It went up more than 1-2 inches wrt to usual. Then I just make it down about 5 inches. Now its in dis located position. I want to know how to remove the door panel. I did remove the arm rest and there was one screw there. removed the triangle near the mirror. afraid to go ahead since there could be more to remove before pulling the panel out. Any clues please?

Is the vehicle under warranty?
