the passenger position,
lift the load floor
panels and latch them
into the seatback.
Then, lift the seatback up and push rearward until it latches. Lower the seat
cushion until it latches in position.

place. Also, pull the safety belt buckles out of the seat cushion pockets, so
they will be available for rear seat passengers to use.
