There is a strap at the back of the seat where the seat belt sockets are. Pull this and the bottom part of the seat flips forward behind the driver and passenger seat, then the seat backs can be folded forward by either pulling the red tag at the back or the lever at the side. The seats then lie flat. The lever for the seat backs has to be pulled again to unlock them so they can be returned to seats. Hope this helps
