3. Pick up the latch plate and pull the belt across you.
4. Push the latch plate into the buckle until it clicks.
Pull up on the latch plate to make sure it is
secure. If the belt isn’t long enough, see
Safety
Belt Extender on page 1-34.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle the
safety belt quickly
if you ever had to.
Don’t let it get twisted.
The lap part of the belt should
be worn
low and snug on
the hips, just touching the thighs. In a crash, this applies
force to the strong pelvic bones. And you’d be less likely
to slide under the lap belt. If you slid under it, the belt
would apply force at your abdomen. This could cause
serious or even fatal injuries. The shoulder belt should go
over the shoulder and across the chest. These parts of
the body are best able
to take belt restraining forces.
The safety belt locks
if there’s a sudden stop or crash,
or
if you pull the belt very quickly out of the retractor.

If the belt stops before it reaches the buckle, tilt the
latch plate and keep pulling until you can buckle it.
Pull up on the latch plate to make sure
it is secure.
If the belt is not long enough, see
Safety Belt
Extender
on page 1-34.
Make sure the release button on the buckle is
positioned
so that you would be able to unbuckle
the safety belt quickly
if you ever had to.
3. To make the lap part tight, pull down on the buckle
end of the belt as you pull up on the shoulder part.

-
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. Children who are
up against, or very close to,
any air bag when
it inflates 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.
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.
The restraint manufacturer’s instructions that come
with the restraint state the weight and height
limitations for a particular child restraint. In addition,
there are many kinds of restraints available for
children with special needs.
Newborn infants need complete support,
including support for the head and neck. This
is
necessary because a newborn infant’s neck is
weak and its head weighs so much compared
with the rest of its body. In a crash, an infant
in a
rear-facing seat settles into the restraint,
so the
crash forces can be distributed across the
strongest part of an infant’s body, the back and
shoulders. Infants always should be secured in
appropriate infant restraints.

The .- Ddy st. -.- re of a young -.1ild 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
thehip 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’s unprotected by any bony structure.
This alone could cause serious or fatal
injuries. Young children always should be
secured in appropriate child restraints. Children who are
L against,
or very close to,
any air bag when
it inflates 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
