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 the 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. There is limited space in the rear seating
area of an extended cab model. If you want to secure a
child restraint in a rear seating position of an extended
cab model, especially in the rear center position, be sure
to study the instructions that came with your child
restraint to see if there is enough room to secure your
seat properly.
If a forward
-facing child seat must be secured in the
vehicle's right front seat, the seat should be moved back
as far as possible. However, it is better to secure the
restraint in a rear seat.
If you want to secure a rear
-facing child restraint in the
right front passenger's seat, turn off the passenger's air
bag. See ªAir Bag Off Switchº and ªSecuring a Child
Restraint in the Right Front Seat Positionº in the Index
for more on this, including important safety information.

1-47
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. Be sure to turn
off the air bag before using a rear
-facing child
restraint in the right front seat 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.
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 beinganchored. 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. 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.Right Front Passenger Position Top Strap Anchor
You'll find the top strap anchor for the right front
passenger seat behind the seat, near the floor.

1-50
When using a child restraint with a top strap in the
center rear position, route the top strap through the
fabric loop on the seatback. Then, raise the head
restraint and attach the top strap to the anchor point
located at the closest outboard position.
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 front passenger seat,
where the seatback meets the seat cushion, and
anchors (A) in the center rear seat, where the seatback
meets the seat cushion. For front passenger seat position,
there is a top tether anchor (C) behind and to the bottom
of the seat to secure the top strap. For center rear seat
positions, there is a top tether anchor (C) near the
driver's side rear seat head restraint to secure the
top strap.
To assist you in locating the lower anchors for this child
restraint system, each seating position with the LATCH
system will have a visible metal anchorage point in the
seat, where the seatback meets the seat cushion.

1-52
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 ªChild Restraintsº 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
There is limited space in the rear seating area. If you
want to secure a child restraint in a rear outside seating
position, be sure to study the instructions that came with
your child restraint to see if there is enough room to
secure your seat properly.

1-54
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.
