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.
1-11

CAUTION: (Continued)
hold it. For example, in a crash at only 25 mph
(40 km/h), a 12-lb. (5.5 kg) baby will suddenly
become a 240-lb. (110 kg) force on a person’s
arms. A baby should be secured in an
appropriate restraint.
{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.
1-31

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. We,
therefore, 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.
Neverput a rear-facing child restraint in the front
passenger seat. 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.
Always secure a rear-facing child restraint in
a rear seat.
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.
1-36

{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.
If you secure a forward-facing child restraint in
the right front passenger 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.

{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.
If you secure a forward-facing child restraint in
the right front passenger 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.
1. Make the belt as long as possible by tilting the latch
plate and pulling it along the belt.
2. Put the child restraint on the seat.
3. Run the vehicle’s safety belt through or around the
restraint. The child restraint instructions will show
you how.

Your vehicle has a right front passenger airbag.
Neverput a rear-facing child restraint in this seat.
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.
Always secure a rear-facing child restraint in
a rear seat.A rear seat is a safer place to secure a forward-facing
child restraint. If you need to secure a forward-facing
child restraint in the right front seat, you will be using the
lap-shoulder belt to secure the child restraint. 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. Because your vehicle has a right front passenger
airbag, always move the seat as far back as it will
go before securing a forward-facing child restraint.
SeeManual Seats on page 1-2.
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.
Tilt the latch plate to adjust the belt if needed.
