CAUTION:
People should never hold a baby in their arms
while riding in a vehicle. A baby doesn't weigh
much
-- until a crash. During a crash a baby will
become so heavy it is not possible to hold it. For
example, in a crash at only 25 mph (40 km/h), a
12
-lb. (5.5 kg) baby will suddenly become a
240
-lb. (110 kg) force on a person's arms. A baby
should be secured in an appropriate restraint.

Q:What are the different types of add-on
child restraints?
A:Add-on child restraints, which are purchased by
the vehicle's owner, are available in four basic
types. Selection of a particular restraint should take
into consideration not only the child's weight,
height and age but also whether or not the restraint
will be compatible with the motor vehicle in which
it will be used.
For most basic types of child restraints, there are
many different models available. When purchasing
a child restraint, be sure it is designed to be used in
a motor vehicle. If it is, the restraint will have a
label saying that it meets federal motor vehicle
safety standards.
The restraint manufacturer's instructions that come
with the restraint state the weight and height
limitations for a particular child restraint. In
addition, there are many kinds of restraints
available for children with special needs.
CAUTION:
Newborn infants need complete support,
including support for the head and neck. This is
necessary because a newborn infant's neck is
weak and its head weighs so much compared with
the rest of its body. In a crash, an infant in a
rear
-facing seat settles into the restraint, so the
crash forces can be distributed across the
strongest part of an infant's body, the back and
shoulders. Infants always should be secured in
appropriate infant restraints.

1-58
CAUTION:
The body structure of a young child is quite
unlike that of an adult or older child, for whom
the safety belts are designed. A young child's hip
bones are still so small that the vehicle's regular
safety belt may not remain low on the hip bones,
as it should. Instead, it may settle up around the
child's abdomen. In a crash, the belt would apply
force on a body area that's unprotected by any
bony structure. This alone could cause serious or
fatal injuries. Young children always should be
secured in appropriate child restraints.
Restraint Systems for Children
An infant car bed (A), a special bed made for use in a
motor vehicle, is an infant restraint system designed to
restrain or position a child on a continuous flat surface.
Make sure that the infant's head rests toward the center
of the vehicle.

1-60
A booster seat (F-G) is a child restraint designed to
improve the fit of the vehicle's safety belt system. Some
booster seats have a shoulder belt positioner, and some
high
-back booster seats have a five-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 five
-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 flat 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
find these instructions on the restraint itself or in a
booklet, or both. These restraints use the belt 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, therefore, 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. Never put a rear
-facing child restraint in
the right front passenger seat. Here's why:
CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger's air bag inflates. This is because the
back of the rear
-facing child restraint would be
very close to the inflating air bag. Always secure
a rear
-facing child restraint in a rear seat.
You may secure a forward-facing child restraint
in the right front seat, but before you do, always
move the front passenger seat as far back as it
will go. It's better to secure the child restraint in
a rear seat.
Wherever 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.

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.
Once you have the top strap anchored, you'll be ready to
secure the child restraint itself. Tighten the top strap
when and as the child restraint manufacturer's
instructions say.Tahoe/Suburban/Yukon/Yukon XL models without
rear seats: Top strap anchor loops are located at the
bottom rear of the front seat cushion for the right front
passenger's position.
Suburban/Yukon XL Models without Rear Seats
Anchor the top strap to this bracket. Once you have the
top strap anchored, you'll be ready to secure the child
restraint itself.

With this system, use the LATCH system instead of the
vehicle's safety belts to secure a child restraint.
CAUTION:
If a LATCH-type child restraint isn't attached to
its anchorage points, the restraint won't be able
to protect a child sitting there. 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. See ºSecuring a Child Restraint in a
Rear Outside Seat Positionº in the Index for
information on how to secure a child restraint in
your vehicle using the vehicle's safety belts.

Securing a Child Restraint Designed for the
LATCH System
1. Find the anchors 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 the anchor points on the child restraint to the
anchors in the vehicle. The child restraint
instructions will show you how.
4. If the child restraint is forward
-facing, attach the top
strap to the top strap anchor. See ªTop Strapº in the
Index. Tighten the top strap according to the child
restraint instructions.
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
strap from the top tether anchor and then disconnect the
anchor points.
Securing a Child Restraint in a Rear
Outside Seat Position
If your child restraint is equipped with the LATCH
system, see ªLower Anchorages and Top Tethers for
Children (LATCH)º in the Index.

You'll be using the lap-shoulder belt. See the earlier
part about the top strap if the 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. 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.
If the shoulder belt goes in front of the child's face or
neck, put it behind the child restraint.
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.

1-70
4. Pull the rest of the shoulder belt all the way out of
the retractor to set the lock.5. To tighten the belt, feed the shoulder belt back into the
retractor while you push down on the child restraint. If
you're using a forward
-facing child restraint, you may
find it helpful to use your knee to push down on the
child restraint as you tighten the belt.
6. Push and pull the child restraint in different
directions to be sure it is secure.
To remove the child restraint, just unbuckle the vehicle's
safety belt and let it go back all the way. The safety belt
will move freely again and be ready to work for an adult
or larger child passenger.
