If you ever pull the shoulder portion of a passenger
belt out all the way, you may engage the child
restraint locking feature. If this happens, just let
the belt go back all the way and start again.
3. 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 1-28.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle the
safety belt quickly if necessary.4. If equipped with a shoulder belt height adjuster,
move it to the height that is right for you. Improper
shoulder belt height adjustment could reduce
the effectiveness of the safety belt in a crash.
See “Shoulder Belt Height Adjustment” later
in this section.
5. To make the lap part tight, pull up on the
shoulder belt.
It may be necessary to pull stitching on the
safety belt through the latch plate to fully tighten
the lap belt on smaller occupants.

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.
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/retailer will order you an extender. 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 fit.
The extender has been designed for adults. Never
use it for securing child seats. To wear it, attach it
to the regular safety belt. For more information,
see the instruction sheet that comes with the
extender.

Infants and Young Children
Everyone in a vehicle needs protection! This includes
infants and all other children. Neither the distance
traveled nor the age and size of the traveler changes
the need, for everyone, to use safety restraints. In fact,
the law in every state in the United States and in every
Canadian province says children up to some age
must be restrained while in a vehicle.
{CAUTION:
Children can be seriously injured or strangled
if a shoulder belt is wrapped around their neck
and the safety belt continues to tighten. Never
leave children unattended in a vehicle and never
allow children to play with the safety belts.Every time infants and young children ride in vehicles,
they should have the protection provided by appropriate
restraints. Children who are not restrained properly can
strike other people, or can be thrown out of the vehicle.
In addition, young children should not use the vehicle’s
adult safety belts alone; they need to use a child restraint.
{CAUTION:
People should never hold an infant in their
arms while riding in a vehicle. An infant does
not weigh much — until a crash. During a
crash an infant 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) infant
will suddenly become a 240 lb (110 kg) force
on a person’s arms. An infant should be
secured in an appropriate restraint.

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 should always be secured in
appropriate infant restraints.
1-34

{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 should always be
secured in appropriate child restraints.
Child Restraint Systems
A rear-facing infant
seat (A) provides
restraint with the
seating surface
against the back
of the infant.
The harness system holds the infant in place and,
in a crash, acts to keep the infant positioned in
the restraint.
A forward-facing
child seat (B) provides
restraint for the
child’s body with
the harness.
1-35

A booster seat (C-D) is a child restraint designed to
improve the fit of the vehicle’s safety belt system.
A booster seat can also help a child to see out
the window.
Securing an Add-On Child Restraint
in the Vehicle
{CAUTION:
A child can be seriously injured or killed in
a crash if the child restraint is not properly
secured in the vehicle. Make sure the child
restraint is properly installed in the vehicle
using the vehicle’s safety belt or LATCH
system, following the instructions that came
with that restraint, and also the instructions
in this manual.
1-36

To help reduce the chance of injury, the child restraint
must be secured in the vehicle. Child restraint systems
must be secured in vehicle seats by lap belts or the
lap belt portion of a lap-shoulder belt, or by the LATCH
system. SeeLower Anchors and Tethers for Children
(LATCH) on page 1-39for more information. A child
can be endangered in a crash if the child restraint is
not properly secured in the vehicle.
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.
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.Securing the Child Within the
Child Restraint
{CAUTION:
A child can be seriously injured or killed in
a crash if the child is not properly secured
in the child restraint. Because there are
different systems, it is important to refer to
the instructions that come with the restraint.
Make sure the child is properly secured,
following the instructions that came with
that restraint.
