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 is not long enough, seeSafety Belt
Extender on page 1-26.
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.
5. To make the lap part tight, pull down on the buckle
end of the belt as you pull up on the shoulder belt.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 would 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 is a sudden stop or crash,
or if you pull the belt very quickly out of the retractor.

2. Push the latch plate into the buckle until it clicks.
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.
When the shoulder belt is pulled out all the way,
it will lock. If it does, let it go back all the way and
start again. If the belt is not long enough, see
Safety Belt Extender on page 1-26.
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.
3. To make the lap part tight, pull down on the buckle
end of the belt as you pull up on the shoulder part.

4. Buckle, position and release the safety belt as
described inRear Seat Passengers on page 1-21.
Make sure that the shoulder belt crosses
the shoulder.
To remove and store the comfort guides, squeeze the
belt edges together so that you can take them out of the
guides. Pull the guide upward to expose its storage
clip, and then slide the guide onto the clip. Turn the
guide and clip inward and in between the seatback and
the interior body, leaving only the loop of the elastic
cord exposed.
Safety Belt Extender
If the vehicle’s safety belt will fasten around you,
you should use it.
But if a safety belt is not long enough, your dealer will
order you an extender. It is free. When you go in to
order it, take the heaviest coat you will wear, so the
extender will be long enough for you. To help avoid
personal injury, do not let someone else use it, and use
it only for the seat it is made to t. The extender has
been designed for adults. Never use it for securing child
seats. To wear it, just attach it to the regular safety
belt. For more information see the instruction sheet that
comes with the extender.

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.

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.
{CAUTION:
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.
1-32

{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.
Child Restraint Systems
An infant car bed (A), a special bed made for use in a
motor vehicle, is an infant restraint system designed
to restrain or position a child on a continuous at
surface. Make sure that the infant’s head rests toward
the center of the vehicle.
1-33

A booster seat (F-G) is a child restraint designed to
improve the t of the vehicle’s safety belt system.
Some booster seats have a shoulder belt positioner,
and some high-back booster seats have a ve-point
harness. A booster seat can also help a child to see out
the window.
Q:How do child restraints work?
A:A child restraint system is any device designed for
use in a motor vehicle to restrain, seat, or position
children. A built-in child restraint system is a
permanent part of the motor vehicle. An add-on
child restraint system is a portable one, which
is purchased by the vehicle’s owner.
For many years, add-on child restraints have used
the adult belt system in the vehicle. To help reduce
the chance of injury, the child also has to be
secured within the restraint. The vehicle’s belt
system secures the add-on child restraint in
the vehicle, and the add-on child restraint’s harness
system holds the child in place within the 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.
