GMC 1996 Suburban Owner's Manual page 18

To fold the seat, pull
up
on
the strap loop at the rear of
the seat cushion.
Then, pull the seat cushion
up and fold it forward.
After folding the seat cushion fully forward, pull the
seatback forward and fold the seatback down until
it is flat.
Then, stow the head
restraints by sliding them
into the rear of the seatback.
Make sure the posts go in
all the way.
To return the seat to the passenger position, first remove
the head restraints by sliding them
out
of the seat
cushion. Lift the seatback up and push rearward all
the way. Then, lower the seat cushion until it latches
in position.
After returning the seat to the passenger position, return
the head restraints to the top of each seatback. Pull
forward on the seatback and up on the seat cushion to
make sure the seat is securely in place.
If the latch plate portion of the center safety belt was put
in the center armrest when the seat was folded, take the
latch plate portion out and place it on the seat. That way,
the center seat position safety belt will be available for
the center rear seat passenger to use.
