Chevrolet 1997 Tahoe Owner's Manual page 20

To create a load floor,
release the panels from the
seatback by pushing
rearward on the latch and
fold them out to cover the
rear seat footwell.
To return the seat to the passenger position, lift the load
floor panels and latch them into the seatback.
Then lift the rear seatback up and push rearward
until it latches. Return the head restraints to their
original positions and lower the seat cushion until it
latches into position.
After returning the seat to the passenger position, pull
forward on the seatback and up on the cushion to make
sure the seat is locked into 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 position safety belt will be available for the
center rear seat passenger to use.
