My new TT has this system and there were no manuals in the packet. I asked the guy in the shop at the Dealer how to retract the slide in an emergency and he said I would have to cut out portions of the interior wall. That answer made my decision to never let them touch my TT! I did my homework and would like to share the info here. The pdf file is a manual and the youtube video shows how to disengage the motors and retract the slide in emergency situations.
