BUICK CENTURY 2003 Service Manual

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.
1-35

{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.
Child Restraint Systems
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 ¯at
surface. Make sure that the infant's head rests toward
the center of the vehicle.
1-36

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.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.
1-37

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.
1-38

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 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.
Neverput 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 in¯ates. This is because
the back of the rear-facing child restraint
would be very close to the in¯ating 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.
1-39

{CAUTION:
A child in a child restraint in the center front
seat can be badly injured or killed by the right
front passenger's air bag if it in¯ates. Never
secure a child restraint in the center front seat.
It's always better to secure a child restraint in
the rear seat. You may secure a forward-facing
child restraint in the right front passenger 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.
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.
1-40

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 an anchor point speci®ed in
Top
Strap Anchor Location on page 1-42. 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.
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.
1-41

Top Strap Anchor Location
The vehicle has top strap anchors installed for the rear
seating positions. You will ®nd them behind the rear
seatback ®ller panel.
In order to get to a bracket, you will have to open the
trim cover.
If your child restraint is equipped with the LATCH
system, see ªLower Anchorages and Top Tethers for
Children (LATCH System)º following.
Lower Anchorages and Top Tethers
for Children (LATCH System)
The vehicle has the LATCH system. You will ®nd
anchors (A) in all three rear seating positions.
This system, designed to make installation of child
restraints easier, does not use the vehicle's safety belts.
Instead it uses vehicles 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).
1-42

In order to use the LATCH system in your vehicle, you
need a child restraint designed for that system.
1-43

To assist you in locating the
lower anchors for this child
restraint system, each
seating position with the
LATCH system has a label
on the seatback at each
lower anchor position.
The labels are located near the base of all three rear
seating positions.
{CAUTION:
If a LATCH-type child restraint isn't attached to
its anchorage points, the restraint won't 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. See ªSecuring a Child Restraint
Designed for the LATCH Systemº or ªSecuring
a Child Restraint in a Rear Seat Positionº in
the Index for information on how to secure a
child restraint in your vehicle.
