To fold the jump seat down, pull down on the pull tab
on the bottom of the seat until the seat is in place, then
move the seatback to a vertical position. To store the
seat, fold the seatback down on the cushion, then push
the entire seat up until it is flush with the trim panel.
Don't let the safety belts be damaged by the hinges or
