I needed to drop the rear seats today to fit a fence panel in the back... On the passenger side, I flicked the lever, the headrest dropped down and the seat flipped up... which I wasn't expecting and found rather cool. (yes I know... sad things impress me). However... on the drivers side, when I pulled the lever, the headrest flipped forward but the seat remained in place and no amount of pushing, pulling and prodding would get it to move. Am I missing something simple? Is there a manual release for the seat because I had a feel around and couldn't find anything.
