When the sunroof is closing the interior panel on the left side. There's a small pin that lifts the interior panel so it can side into a place that is design to pull it up so that it can close.

 

Welcome soundking3, please introduce yourself and your car in the New Members Area. I myself do not have a sunroof, but I would expect a quick reply from someone who does... please be patient.
But in the meantime, be sure to put this in your favorites... JagRepair.com - Jaguar Repair Information Resource ...you will find much useful information there. I also highly recommend reviewing the sticky's at the top of this forum for more info.
