Rear Folding Seat (&Door Utility Model)
If your vehicle has a 60/40 rear seat, either side may be folded down to give
you more cargo space.
Before folding, place the latch plate portion of the center safety belt in the
center a m rest. That way, the center safety belt will be out of the way when
the seat is folded and also will easily available for passengers to use when
the seat is returned to the passenger position. Also, make sure that nothing is
under or in front of the seat. When the seat
is
folded, it will lay flat on the
floor.
First, remove the head
restraints. Push the
release buttons at the
bottom of each head
restraint height adjust
post and slide the head
restraint out of the
height adjust tubes.
Set the head restraints aside for now. You will stow them in their proper
position after you are done folding the seat.
