GMC 2004 Yukon XL Owner's Manual page 75

There is no top strap anchor in the right front passenger's
position. Do not secure a child seat in this position if a
national or local law requires that the top strap be
anchored, or if the instructions that come with the
child restraint say that the top strap must be anchored.
See Top Strap on page 1-55 if your child restraint
has one.
You will be using the lap-shoulder belt to secure the
child restraint in this position. See Top Strap on
page 1-55 if your child restraint has one. Be sure to
follow the instructions that came with the child restraint.
Secure the child in the child restraint when and as
the instructions say.
1. Your vehicle has a right front passenger's frontal air
bag. See Passenger Sensing System on page 1-81.
General Motors recommends that rear-facing child
restraints be secured in a rear seat, even if the air
bag is off. If your child restraint is forward-facing,
move the seat as far back as it will go before
securing the child restraint in this seat. See Power
Seats on page 1-4 or Manual Seats on page 1-3.
When the passenger sensing system has turned off
the right front passenger's frontal air bag, the off
indicator in the passenger air bag status indicator
should light and stay lit when you turn the ignition to
RUN or START. See Passenger Air Bag Status
Indicator on page 3-42.
2. Put the child restraint on the seat.
3. Pick up the latch plate, and run the lap and shoulder
portions of the vehicle's safety belt through or
around the restraint. The child restraint instructions
will show you how.
4. Buckle the belt. Make sure the release button is
positioned so you would be able to unbuckle the
safety belt quickly if you ever had to.
