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

Safety Belt Use During Pregnancy
Safety belts work for everyone, including pregnant
women. Like all occupants, they are more likely to be
seriously injured if they do not wear safety belts.
A pregnant woman should wear a lap-shoulder belt, and
the lap portion should be worn as low as possible,
below the rounding, throughout the pregnancy.
The best way to protect the fetus is to protect the
mother. When a safety belt is worn properly, it is more
likely that the fetus will not be hurt in a crash. For
pregnant women, as for anyone, the key to making
safety belts effective is wearing them properly.
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 Passenger Position
If your vehicle has front and rear bench seats, someone
can sit in the center positions.
When you sit in the center rear seat position of a crew
cab, you have a lap-shoulder belt which is similar to
the rear outside seat positions. To learn how to wear this
belt see “Lap-Shoulder Belt” underRear Seat
Passengers on page 1-27.

{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.

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

Do not use child restraints in the center front seat
position. The restraints will not work properly.
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 your vehicle has the passenger sensing system or the
airbag off switch and you need to secure a rear-facing
child restraint in the right front passenger’s seat,
the passenger’s frontal airbag must be off. See
Passenger Sensing System on page 1-76,Airbag Off
Switch on page 1-73,Securing a Child Restraint in
the Right Front Seat Position (Regular and Extended
Cab) (With Airbag Off Switch) on page 1-56orSecuring
a Child Restraint in the Right Front Seat Position
(Regular and Extended Cab) (With Passenger Sensing
System) on page 1-62for more on this including
important safety information.
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 much 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.

6. To tighten the belt, push down on the child restraint,
pull the shoulder portion of the belt to tighten the lap
portion of the belt and feed the shoulder belt back
into the retractor. If you are using a forward-facing
child restraint, you may nd it helpful to use your
knee to push down on the child restraint as you
tighten the belt. You should not be able to pull more
of the belt out of the retractor once the lock has
been set.
7. Push and pull the child restraint in different directions
to be sure it is secure.To remove the child restraint, just unbuckle the vehicle’s
safety belt and let it go back all the way. The safety
belt will move freely again and be ready to work for an
adult or larger child passenger.
Securing a Child Restraint in the
Right Front Seat Position (Regular
and Extended Cab) (With Airbag
Off Switch)
Your vehicle has a right front passenger airbag. There
is a switch on the instrument panel that you can
use to turn off the right front passenger’s frontal airbag.
See the following illustration. Your switch may vary
slightly. SeeAirbag Off Switch on page 1-73for more
on this, including important safety information and
illustrations of alternate switch designs.
