Questions and Answers About
Safety Belts
Q:Will I be trapped in the vehicle after an accident
if I am wearing a safety belt?
A:Youcouldbe — whether you are wearing a safety
belt or not. But you can unbuckle a safety belt,
even if you are upside down. And your chance of
being conscious during and after an accident,
so youcanunbuckle and get out, ismuchgreater if
you are belted.
Q:If my vehicle has airbags, why should I have to
wear safety belts?
A:Airbags are in many vehicles today and will be in
most of them in the future. But they are
supplemental systems only; so they workwith
safety belts — not instead of them. Every airbag
system ever offered for sale has required the use of
safety belts. Even if you are in a vehicle that has
airbags, you still have to buckle up to get the most
protection. That is true not only in frontal collisions,
but especially in side and other collisions.
Q:If I am a good driver, and I never drive far from
home, why should I wear safety belts?
A:You may be an excellent driver, but if you are in an
accident — even one that is not your fault — you
and your passengers can be hurt. Being a good
driver does not protect you from things beyond your
control, such as bad drivers.
Most accidents occur within 25 miles (40 km) of
home. And the greatest number of serious injuries
and deaths occur at speeds of less than
40 mph (65 km/h).
Safety belts are for everyone.
How to Wear Safety Belts Properly
This part is only for people of adult size.
Be aware that there are special things to know about
safety belts and children. And there are different
rules for smaller children and babies. If a child will be
riding in your vehicle, seeOlder Children on page 1-26
orInfants and Young Children on page 1-29. Follow
those rules for everyone’s protection.
First, you will want to know which restraint systems your
vehicle has.
We will start with the driver position.
1-13

{CAUTION:
Children who are up against, or very close to,
any airbag when it inates can be seriously
injured or killed. Airbags plus lap-shoulder
belts offer protection for adults and older
children, but not for young children and
infants. Neither the vehicle’s safety belt system
nor its airbag 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.
1-30

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, “Never put a rear-facing child seat in the
front.” This is because the risk to the rear-facing child is
so great, if the airbag deploys.
1-34

{CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger’s airbag inates. This is because
the back of the rear-facing child restraint
would be very close to the inating airbag.
Even though the passenger sensing system is
designed to turn off the passenger’s frontal
airbag if the system detects a rear-facing child
restraint, no system is fail-safe, and no one
can guarantee that an airbag 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 airbag
is off.
If you need to 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 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 “top tether.”
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.
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.
1-35

Securing a Child Restraint in the
Center Seat Position
Many child restraints are too wide to be correctly
secured in the center rear seat, although some of them
will t there. If the center seat position is too narrow
for your child restraint, secure it in a rear outside seat
position.
If you secure a child restraint in the center seat position,
follow the instructions inSecuring a Child Restraint in
a Rear Outside Seat Position on page 1-41.
Securing a Child Restraint in the
Right Front Seat Position
Your vehicle has a right front passenger airbag. A rear
seat is a safer place to secure a forward-facing child
restraint. SeeWhere to Put the Restraint on page 1-34.
In addition, your vehicle has a passenger sensing
system. The passenger sensing system is designed to
turn off the right front passenger’s frontal airbag
when an infant in a rear-facing infant seat or a small
child in a forward-facing child restraint or booster seat is
detected. SeePassenger Sensing System on page 1-58
andPassenger Airbag Status Indicator on page 3-37
for more information on this including important
safety information.A label on your sun visor says, “Never put a rear-facing
child seat in the front.” This is because the risk to the
rear-facing child is so great, if the airbag deploys.
{CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger’s airbag inates. This is because
the back of the rear-facing child restraint
would be very close to the inating airbag.
Even though the passenger sensing system is
designed to turn off the passenger’s frontal
airbag if the system detects a rear-facing child
restraint, no system is fail-safe, and no one can
guarantee that an airbag 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 airbag is off.
If you need to secure a forward-facing child restraint in
the right front seat position, move the seat as far
back as it will go before securing the forward-facing
child restraint. SeePower Seats on page 1-2.
1-43

If your child restraint is equipped with the LATCH
system, seeLower Anchorages and Top Tethers for
Children (LATCH System) on page 1-38.
There is no top strap anchor at the right front 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. See
Top Strap on page 1-35if your child restraint has one.
You will 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. Your vehicle has a right front passenger’s frontal
airbag. SeePassenger Sensing System on
page 1-58. General Motors recommends that
rear-facing child restraints be secured in a rear seat,
even if the airbag is off. If your child restraint is
forward-facing, move the seat as far back as it will
go before securing the child restraint in this
seat. SeePower Seats on page 1-2.
When the passenger sensing system has turned off
the right front passenger’s frontal airbag, the off
indicator in the passenger airbag status indicator
should light and stay lit when you turn the ignition to
RUN or START. SeePassenger Airbag Status
Indicator on page 3-37.
2. Put the child restraint on the seat.
3. 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.
