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.

Right Front Passenger Position
To learn how to wear the right front passenger’s safety
belt properly, seeDriver Position on page 1-32.
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 seating position in the
second row you have a lap-shoulder belt which is
similar to the belt in the rear outside seating positions.
To learn how to wear this belt see “Lap-Shoulder
Belt” underRear Outside Passenger Positions
on page 1-42.

{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.
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.
{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. We recommend 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.
Do not use child restraints in the center front seat
position. The restraints will not work properly.
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.

Securing a Child Restraint in the
Center Front Seat Position
{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 this position. The restraints
will not work properly.
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 1-57.
In addition, your vehicle may have 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 1-82andPassenger Airbag Status
Indicator on page 3-38for 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. We recommend 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 1-4orManual
Seats on page 1-3.
If your child restraint is equipped with the LATCH system,
seeLower Anchors and Tethers for Children (LATCH)
on page 1-58.There is no top tether 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 tether be
anchored or if the instructions that come with the
child restraint say that the top tether must be anchored.
SeeLower Anchors and Tethers for Children (LATCH)
on page 1-58if the child restraint has a top tether.
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 1-82. 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 1-4orManual Seats
on page 1-3.
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 3-38.
2. Put the child restraint on the seat.
