or the safety belts!
With safety belts, you slow down as the vehicle does.
You get more time to stop. You stop over more distance,
and your strongest bones take the forces. That is why
safety belts make such good sense.
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.
1-15

Right Front Passenger Position
To learn how to wear the right front passenger’s safety
belt properly, seeDriver Position on page 1-16.
The right front passenger’s safety belt works the same
way as the driver’s safety belt — except for one
thing. If you ever pull the shoulder portion of the belt out
all the way, you will engage the child restraint locking
feature which may turn off the passenger’s frontal
airbag. If this happens unintentionally, just let the belt
go back all the way and start again.
Center Front Passenger Position
Lap Belt
If your vehicle has a front bench seat, someone can sit
in the center position.
When you sit in the center front seating position, you
have a lap safety belt, which has no retractor. To make
the belt longer, tilt the latch plate and pull it along
the belt.
1-25

{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.
1-35

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.
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.
Securing the Child Within the Child
Restraint
There are several systems for securing the child within
the child 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.
{CAUTION:
A child can be seriously injured or killed in a
crash if the child is not properly secured in the
child restraint. Make sure the child is properly
secured, following the instructions that came
with that restraint.
Because there are different systems, it is important to
refer to the instructions that come with the restraint.
A child can be endangered in a crash if the child is not
properly secured in the child restraint.
Where to Put the Restraint
Accident statistics show that children are safer if they
are restrained in the rear rather than the front seat.
We recommend 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 may have a label on your sun visor that
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.
1-40

Never put a child in a rear-facing child restraint in the right
front passenger seat unless your vehicle has the
passenger sensing system or an airbag off switch and the
passenger airbag status indicator or the airbag off light
shows off. Never put a rear facing child restraint in the
right front passenger seat unless the airbag is off. Here
is why:
{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. Be sure the
airbag is off before using a rear-facing child
restraint in the right front seat position.
Even though the passenger sensing system or
airbag off switch are designed to turn off the
passenger’s frontal airbag under certain
conditions, 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
CAUTION: (Continued)
CAUTION: (Continued)
recommends that rear-facing child restraints
be transported in vehicles with a rear seat that
will accommodate a rear-facing child restraint,
whenever possible.
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.
{CAUTION:
A child in a child restraint in the center front
seat can be badly injured or killed by the right
front passenger’s airbag if it inates. Never
secure a child restraint in the center front seat.
It is always better to secure a child restraint in
the rear seat.
Do not use child restraints in the center front seat
position. The restraints will not work properly.
