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.
CAUTION: (Continued)
CAUTION: (Continued)
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.

1-37
CAUTION:
Children who are up against, or very close to, any
air bag when it inflates can be seriously injured
or killed. Air bags plus lap
-shoulder belts offer
outstanding protection for adults and older
children, but not for young children and infants.
Neither the vehicle's safety belt system nor its air
bag system is designed for them. Young children
and infants need the protection that a child
restraint system can provide.
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.

1-38
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.
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.
A rear-facing infant seat (B) provides restraint with
the seating surface against the back of the infant. The
harness system holds the infant in place and, in a crash,
acts to keep the infant positioned in the restraint.

1-40
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 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.

1-41
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.

1-42 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 outside position
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 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
outside position.
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 outside position.
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.

1-43 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, don't use the restraint unless it is
anchored properly.
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. Raise the head restraint
and route the top strap under it.

1-44
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.
Anchor brackets for the rear seat positions are located
on the floor in the cargo area of your vehicle. Do not
use the rear tie
-down brackets near the liftgate for top
strap tethers.
Lower Anchorages and Top Tethers for
Children (LATCH System)
Your vehicle may have the LATCH system. If it does,
you'll find anchors (A) in the rear outside seat positions.
To assist you in locating the lower anchors for this child
restraint system, each seating position with the LATCH
system will have two metal tabs where the seat cushion
meets the seatback.

1-45
In order to use the system, you need either a
forward
-facing child restraint that has attaching
points (B) at its base and a top tether anchor (C), or a
rear
-facing child restraint that has attaching points (B),
as shown here.
