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.

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 43.
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, just
let the belt go back all the way and start again.

{CAUTION:
Children who are up against, or very close
to, any airbag when it in ates 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.

Securing the Child Within the Child
Restraint
There are several systems for securing the child
within the child restraint. One system, the
three-point harness, has straps that come down
over each of the infant’s shoulders and buckle
together at the crotch. The ve-point harness
system has two shoulder straps, two hip straps,
and a crotch strap. A shield may take the place
of hip straps. A T-shaped shield has shoulder
straps that are attached to a at pad which
rests low against the child’s body. A shelf- or
armrest-type shield has straps that are attached
to a wide, shelf-like shield that swings up or to
the side.
{CAUTION:
A child can be seriously injured or killed in
a crash if the child is not properly secured
in the child restraint. Make sure the child
is properly secured, following the
instructions that came with that restraint.Because there are different systems, it is important
to refer to the instructions that come with the
restraint. A child can be endangered in a crash
if the child is not properly secured in the child
restraint.
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 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.
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.
72
Page 73 of 608
{CAUTION:
A child in a rear-facing child restraint can
be seriously injured or killed if the right
front passenger’s airbag in ates. This is
because the back of the rear-facing child
restraint would be very close to the
in ating airbag. Be sure the airbag is off
before using a rear-facing child restraint
in the passenger’s position.
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.
CAUTION: (Continued)
CAUTION: (Continued)
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.

6. If your child restraint manufacturer
recommends using a top tether, and the
position that you are using has a top tether
anchor, attach and tighten the top tether to the
top tether anchor. Refer to the instructions
that came with the child restraint and toLower
Anchors and Tethers for Children (LATCH)
on page 74.
7. Push and pull the child restraint in different
directions to be sure it is secure.
To remove the child restraint, if the top tether is
attached to the top tether anchor, disconnect
it. 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
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
in ates. 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.
