A forward-facing child seat (C-E) provides restraint for
the child's body with the harness and also sometimes
with surfaces such as T-shaped or shelf-like shields.A booster seat (F-G) is a child restraint designed to
improve the ®t of the vehicle's safety belt system. Some
booster seats have a shoulder belt positioner, and
some high-back booster seats have a ®ve-point harness.
A booster seat can also help a child to see out the
window.

Q:How do child restraints work?
A:A child restraint system is any device designed for
use in a motor vehicle to restrain, seat, or position
children. A built-in child restraint system is a
permanent part of the motor vehicle. An add-on
child restraint system is a portable one, which
is purchased by the vehicle's owner.
For many years, add-on child restraints have used
the adult belt system in the vehicle. To help
reduce the chance of injury, the child also has to be
secured within the restraint. The vehicle's belt
system secures the add-on child restraint in the
vehicle, and the add-on child restraint's harness
system holds the child in place within the restraint.
One system, the three-point harness, has straps that
come down over each of the infant's shoulders and
buckle together at the crotch. The ®ve-point harness
system has two shoulder straps, two hip straps and a
crotch strap. A shield may take the place of hip
straps. A T-shaped shield has shoulder straps that
are attached to a ¯at pad which rests low against the
child's body. A shelf- or armrest-type shield has
straps that are attached to a wide, shelf-like shield
that swings up or to the side.When choosing a child restraint, be sure the child
restraint is designed to be used in a vehicle. If it is, it
will have a label saying that it meets federal motor
vehicle safety standards.
Then follow the instructions for the restraint. You may
®nd these instructions on the restraint itself or in a
booklet, or both. These restraints use the belt system or
the LATCH system in your vehicle, but the child also
has to be secured within the restraint to help reduce the
chance of personal injury. When securing an add-on
child restraint, refer to the instructions that come with the
restraint which may be on the restraint itself or in a
booklet, or both, and to this manual. The child restraint
instructions are important, so if they are not available,
obtain a replacement copy from the manufacturer.
Where to Put the Restraint
Accident statistics show that children are safer if they
are restrained in the rear rather than the front seat.
General Motors recommends that child restraints
be secured in a rear seat, including an infant riding in a
rear-facing infant seat, a child riding in a forward-facing
child seat and an older child riding in a booster seat.
Your vehicle has a rear seat that will accommodate
a rear-facing child restraint. A label on your sun visor
says,²Never put a rear-facing child seat in the
front.²This is because the risk to the rear-facing child is
so great, if the air bag deploys.
1-56

Page 63 of 468

{CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger's air bag in¯ates. This is because
the back of the rear-facing child restraint
would be very close to the in¯ating air bag.
Even though the passenger sensing system is
designed to turn off the passenger's frontal air
bag if the system detects a rear-facing child
restraint, no system is fail-safe, and no one
can guarantee that an air bag will not deploy
under some unusual circumstance, even
though it is turned off. General Motors
recommends that rear-facing child restraints
be secured in the rear seat, even if the air bag
is off.
If you secure a forward-facing child restraint in
the right front seat, always move the front
passenger seat as far back as it will go. It is
better to secure the child restraint in a rear seatWherever you install it, be sure to secure the child
restraint properly.
Keep in mind that an unsecured child restraint can
move around in a collision or sudden stop and injure
people in the vehicle. Be sure to properly secure
any child restraint in your vehicle ± even when no child
is in it.
Top Strap
Some child restraints have a top strap, or ªtop tether.º
It can help restrain the child restraint during a collision.
For it to work, a top strap must be properly anchored
to the vehicle. Some top strap-equipped child restraints
are designed for use with or without the top strap
being anchored. Others require the top strap always to
be anchored. Be sure to read and follow the
instructions for your child restraint. If yours requires that
the top strap be anchored, do not use the restraint
unless it is anchored properly.
1-57

Page 64 of 468

If the child restraint does not have a top strap, one can
be obtained, in kit form, for many child restraints.
Ask the child restraint manufacturer whether or not a kit
is available.
In Canada, the law requires that forward-facing child
restraints have a top strap, and that the strap be
anchored. In the United States, some child restraints
also have a top strap. If your child restraint has a
top strap, it should be anchored.Anchor the top strap to one of the following anchor
points. Be sure to use an anchor point located on the
same side of the vehicle as the seating position
where the child restraint will be placed.
If you have an adjustable head restraint, route the top
strap under it.
{CAUTION:
Each top tether bracket is designed to anchor
only one child restraint. Attaching more than
one child restraint to a single bracket could
cause the anchor to come loose or even break
during a crash. A child or others could be
injured if this happens. To help prevent injury
to people and damage to your vehicle, attach
only one child restraint per bracket.
Once you have the top strap anchored, you will be
ready to secure the child restraint itself. Tighten the top
strap when and as the child restraint manufacturer's
instructions say.

Top Strap Anchor Location
Yukon XL Denali models:A child restraint with a top
strap should only be used in the second or third
row. Don't use a child restraint with a top strap in the
front seat because there's no place to anchor the
top strap.
An anchor loop bracket for a top strap is located at the
bottom rear of the seat cushion for each seating
position in the second row, and for the center seating
position in the third row on bench seats.

Lower Anchorages and Top Tethers
for Children (LATCH System)
Your vehicle has the LATCH system. You will ®nd
anchors (A) in the center and right side passenger
second row seating positions for bench seats, and the
outboard passenger positions for bucket seats.This system, designed to make installation of child
restraints easier, does not use the vehicle's safety belts.
Instead, it uses vehicle anchors (A, B) and child
restraint attachments to secure the restraints. Some
restraints also use another vehicle anchor to secure a
top tether strap (C).
1-61

Page 68 of 468

In order to use the LATCH system in your vehicle, you
need a child restraint designed for that system.
To assist you in locating the lower anchors for this child
restraint system, each seating position with the
LATCH system has a visible metal anchorage point in
the seat where the seatback meets the seat cushion.
{CAUTION:
If a LATCH-type child restraint is not attached
to its anchorage points, the restraint will not
be able to protect the child correctly. In a
crash, the child could be seriously injured or
killed. Make sure that a LATCH-type child
restraint is properly installed using the
anchorage points, or use the vehicle's safety
belts to secure the restraint, following the
instructions that came with that restraint, and
also the instructions in this manual.

Securing a Child Restraint Designed
for the LATCH System
1. Find the LATCH anchorages for the seating
position you want to use, where the bottom of the
seatback meets the back of the seat cushion.
2. Put the child restraint on the seat.
3. Attach and tighten the LATCH attachments on the
child restraint to the LATCH anchorages in the
vehicle. The child restraint instructions will
show you how.
4. If the child restraint is forward-facing, attach and
tighten the top tether to the top tether anchorage.
The child restraint instructions will show you
how. Also see
Top Strap on page 1-57.
5. Push and pull the child restraint in different
directions to be sure it is secure.
To remove the child restraint, simply unhook the top
tether from the top tether anchorage and then
disconnect the LATCH attachments from the LATCH
anchorages.
Securing a Child Restraint in a Rear
Outside Seat Position
If your child restraint is equipped with the LATCH
system, seeLower Anchorages and Top Tethers for
Children (LATCH System) on page 1-61. SeeTop Strap
on page 1-57if the child restraint has one.
There is no top strap anchor at the third row driver side
seating 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.

If your child restraint does not have the LATCH system,
you'll be using the lap-shoulder belt to secure the child
restraint in this position. 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. Put the restraint on the seat.
2. 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.3. 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.
4. Pull the rest of the shoulder belt all the way out of
the retractor to set the lock.
