Looking at the Service Manual, this is not something you want to have to do. If you can get the trunk lid open to the reverse open position, which if you don't have power, isn't easy, you could manually fold the top up with a few tools and the help of another person. The service manual has you completely removing the trunk lid from the vehicle. Then you have to figure out how to manually fold in the close-out panel "wings". Has anyone out there ever had the issue of the top not going up, or had experience manually folding up the top? Not a need - just a what if!
