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’s why
safety belts make such good sense.
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.

Every time infants and young children ride in vehicles,
they should have the protection provided by the
appropriate restraint. Young children should not use the
vehicles safety belts without an additional restraint,
unless there is no other choice.

{CAUTION:
People should never hold a baby in their arms
while riding in a vehicle. A baby does not
weigh much -- until a crash. During a crash a
baby will become so heavy it is not possible to
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.
1-37

{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 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.
1-38

{CAUTION:
The body structure of a young child is quite
unlike that of an adult or older child, for whom
the safety belts are designed. A young child’s
hip bones are still so small that the vehicle’s
regular safety belt may not remain low on the
hip bones, as it should. Instead, it may settle
up around the child’s abdomen. In a crash, the
belt would apply force on a body area that is
unprotected by any bony structure. This alone
could cause serious or fatal injuries. Young
children always should be secured in
appropriate child restraints.

Where to Put the Restraint
Passenger Vans without an Air Bag Off
Switch
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. If your vehicle has a
front passenger air bag,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 air bag inates.
This is because the back of the rear-facing
child restraint would be very close to the
inating air bag. If your vehicle has a right
front passenger’s air bag, 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.
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.

Passenger Vans with an Air Bag Off
Switch
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. If you
need to secure a rear-facing child restraint in the
right front passenger’s seat, turn off the passenger’s air
bag. SeeAir Bag Off Switch on page 1-77and
Securing a Child Restraint in the Right Front Seat
Position on page 1-65for more on this, including
important safety information.
{CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the 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 to turn off the air bag
before using a rear-facing child restraint in the
right front seat position.
CAUTION: (Continued)
CAUTION: (Continued)
Even though the air bag off switch is designed
to turn off the passenger’s frontal air bag, 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. We recommend 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 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.
