Questions and Answers About
Safety Belts
Q:Won’t I be trapped in the vehicle after an
accident if I’m wearing a safety belt?
A:Youcouldbe – whether you’re wearing a safety
belt or not. But you can unbuckle a safety belt,
even if you’re 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 air bags, why should I have to
wear safety belts?
A:Air bags 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 air bag
system ever offered for sale has required the use of
safety belts. Even if you’re in a vehicle that has
air bags, you still have to buckle up to get the most
protection. That’s true not only in frontal collisions,
but especially in side and other collisions.
Q:If I’m 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’re in an
accident – even one that isn’t your fault – you and
your passengers can be hurt. Being a good
driver doesn’t 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.

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 air bag. 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 1-26.
1-24

{CAUTION:
Children who are up against, or very close to,
any air bag when it inates can be seriously
injured or killed. Air bags plus lap-shoulder
belts offer outstanding protection for adults and

CAUTION: (Continued)
older children, but not for young children and
infants. Neither the vehicle’s safety belt system
nor its air bag 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.
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.
1-36

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 and/or an air bag
off switch and the air bag status indicator shows off.
Never put a rear facing child restraint in the right front
passenger seat unless the air bag 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 air bag inates. This is because the
back of the rear-facing child restraint would be
very close to the inating air bag. Be sure the air
bag is off before using a rear-facing child
restraint in the right front seat position.
CAUTION: (Continued)
CAUTION: (Continued)
Even though the passenger sensing system
and/or air bag off switch are designed to turn
off the passenger’s frontal air bag under
certain conditions, no system is fail-safe, and
no one can guarantee that an air bag 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 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.
1-41

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
and/or the air bag off switch and you need to secure a
rear-facing child restraint in the right front passenger’s
seat, the passenger’s frontal air bag must be off.
SeePassenger Sensing System on page 1-78,Securing
a Child Restraint in the Right Front Seat Position
(Regular and Extended Cab) on page 1-61,Securing a
Child Restraint Designed for the LATCH System
(Rear) on page 1-48orSecuring a Child Restraint
Designed for the LATCH System (Front) on page 1-49,
andAir Bag Off Switch on page 1-73for 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, 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.

3. Attach and tighten the LATCH attachments on the
child restraint to the LATCH anchorages in the
vehicle. The child restraint instructions will show
you how.
4. If the child restraint is forward-facing, attach and
tighten the top tether to the top tether anchorage.
The child restraint instructions will show you
how. Also seeTop Strap on page 1-42.
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
tether from the top tether anchorage and then
disconnect the LATCH attachments from the LATCH
anchorages.
Securing a Child Restraint Designed
for the LATCH System (Front)
Your vehicle has a right front passenger air bag. There
is a switch on the instrument panel that you can use
to turn off the right front passenger’s frontal air bag. See
the following illustration. Your switch may vary slightly.
SeeAir Bag Off Switch on page 1-73for more on
this, including important safety information and
illustrations of alternate switch designs.
{CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger’s air bag inates. This is because
the back of the rear facing child restraint
would be very close to the inating air bag. Be
sure the air bag is off before using a
rear-facing child restraint in the right front
seat position.
Even though the passenger sensing system
and/or air bag off switch are designed to turn
off the passenger’s frontal air bag under
certain conditions, no system is fail-safe, and
no one can guarantee that an air bag 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.
1-49

In addition to the air bag off switch, your vehicle may
have the passenger sensing system. The passenger
sensing system is designed to turn off the right
front passenger’s frontal air bag when an infant or small
child in a rear-facing infant seat, a forward-facing
child restraint, or a booster seat is detected. SeeAir
Bag Off Switch on page 1-73andPassenger Sensing
System on page 1-78.Never put a rear facing child restraint in the right front
passenger’s seat unless the air bag 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 air bag inates. This is because
the back of the rear-facing child restraint
would be very close to the inating air bag. Be
sure the air bag is off before using a
rear-facing child restraint in the right front seat
position. If you secure a forward-facing child
restraint in the right front seat, always move
the right front passenger seat as far back as it
will go.
A rear seat is a safer place to secure a forward facing
child restraint. SeeWhere to Put the Restraint on
page 1-41. 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 a
forward-facing child restraint. SeeManual Seats on
page 1-3orPower Seats on page 1-4.
