Rear Folding Seat (Utility Model)
If your vehicle has a rear seat, the seat can be folded flat for more cargo
space. Before folding, make sure nothing is under or in front of the seat.
When the seat is folded,
it
will lay flat on the floor.
To fold the seat, pull
on the lever at the
front of the seat
cushion marked
RELEASE.
Then, using the handle
at the side of the
seatback, pull the
seatback forward and
fold it into the seat
cushion.
While the seat is in the folded position, hang the latch plate end of the outer
passenger position safety belts on the hooks at the top of each retractor
cover, out of the way.
To return the seat to the passenger position, just lift up on the seatback and
push it rearward until
it
latches.
After returning the seat to the passenger position, pull forward on the
seatback to make sure it is locked in place. Also, return the safety belts
to their original position, so they will be available for rear seat passengers
to use.
