GMC 2001 Yukon XL Owner's Manual page 24

Check to see that the buckles on the driver's side
seatback are accessible to the outboard and center
occupant and are not under the seat cushions.
If you have removed the head restraints to fold the rear
bucket seat, be sure to reinstall them on the seatback
after it has been returned to the normal seating position.
Be sure to return the head restraints to the upright
position on utility models.
Entry to the Third Seat
Suburban/Yukon XL: The passenger's side of the
second row 60/40 or rear bucket seats has an easy entry
feature. This makes it easy to get in and out of the
third seat, if your vehicle has one.
To operate the easy entry seat, turn the release lever,
located near the back of the seat rearward.
Tilt the seatback toward the front of the vehicle by
pulling the top of the seatback forward.
When you do, the seat bottom will release. Just pull the
seat forward until it stops.
Be sure to return the seat to the passenger position when
finished. Pull forward and push rearward on the seat to
make sure it is locked in place.
Folding the Third Seat
Utility: The seatback of the third seat (if equipped) in
utility models also folds down on the floor.
To return the seat to the passenger position, pull up
on the release lever labeled 1 and then pull up on the
seatback until it locks into the upright position.
Push forward on the seatback to make sure it is
locked into position.
To fold the seatback down,
pull up on the release lever,
labeled 1, located on the
rear of the seatback. Then
push the seatback forward.
