Chevrolet 2000 Tahoe Owner's Manual page 22

On Suburban/Yukon XL models with bucket seats,
the seatbacks can be reclined. To adjust the seatback,
pull the lever located at the base of the back forward.
Release the lever to lock the seatback where you want it.
Pull the lever again and the seatback will go to an
upright position. In order to fold the back of a bucket
seat into a horizontal load floor, the back must be in its
full upright position and not reclined.
On Suburban/Yukon XL models with 60/40 split bench
seats, before folding the rear seat on the driver's side,
insert the two buckles into the retainer in the seatback.
That way, the buckles will be out of the way when the
seat is folded and will be 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
and that the head restraints are completely lowered.
After folding the seat cushion fully forward, pull the
seatback forward and fold the seatback down until it is
flat. If the seatback cannot fold flat because it interferes
with the cushion, try moving the front seat forward
and/or bringing the front seatback more upright.
On the passenger side of Suburban/Yukon XL models,
the lever at the base of the seat must be rotated rearward
to release the seatback.
To fold, pull up on the strap
loop at the rear of the seat
cushion. Then, pull the
seat cushion up and fold
it forward.
