Child Restraints
Older Children
Older children who have outgrown booster seats should
wear the vehicle's safety belts.The manufacturer's instructions that come with the
booster seat, state the weight and height limitations for
that booster. Use a booster seat with a lap-shoulder belt
until the child passes the below fit test:
.Sit all the way back on the seat. Do the knees
bend at the seat edge? If yes, continue. If no,
return to the booster seat.
.Buckle the lap-shoulder belt. Does the shoulder
belt rest on the shoulder? If yes, continue. If no, try
using the rear safety belt comfort guide. See
“Rear
Safety Belt Comfort Guides” underLap-Shoulder
Belt
on page 2‑40for more information. If the
shoulder belt still does not rest on the shoulder,
then return to the booster seat.
.Does the lap belt fit low and snug on the hips,
touching the thighs? If yes, continue. If no, return
to the booster seat.
.Can proper safety belt fit be maintained for length
of trip? If yes, continue. If no, return to the
booster seat.
If you have the choice, a child should sit in a position
with a lap-shoulder belt and get the additional restraint
a shoulder belt can provide.

Q: What is the proper way to wear safety belts?
A:An older child should wear a lap-shoulder belt and
get the additional restraint a shoulder belt can
provide. The shoulder belt should not cross the face
or neck. The lap belt should fit snugly below the
hips, just touching the top of the thighs. This applies
belt force to the child's pelvic bones in a crash.
It should never be worn over the abdomen, which
could cause severe or even fatal internal injuries in
a crash.
Also see “Rear Safety Belt Comfort Guides” under
Lap-Shoulder Belt on page 2‑40.
According to accident statistics, children and infants are
safer when properly restrained in the rear seating
positions than in the front seating positions.
In a crash, children who are not buckled up can strike
other people who are buckled up, or can be thrown out
of the vehicle. Older children need to use safety belts
properly.
{WARNING:
Never do this.
Never allow two children to wear the same safety
belt. The safety belt can not properly spread the
impact forces. In a crash, the two children can be
crushed together and seriously injured. A safety
belt must be used by only one person at a time.
2-50

{WARNING:
Never do this.
Never allow a child to wear the safety belt with the
shoulder belt behind their back. A child can be
seriously injured by not wearing the lap-shoulder
belt properly. In a crash, the child would not be
restrained by the shoulder belt. The child could
move too far forward increasing the chance of
head and neck injury. The child might also slide
under the lap belt. The belt force would then be
applied right on the abdomen. That could cause
serious or fatal injuries. The shoulder belt should
go over the shoulder and across the chest.
2-51

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.
{WARNING:
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.
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. Every time infants
and young children ride in vehicles, they should have
the protection provided by appropriate child restraints. Children who are not restrained properly can strike
other people, or can be thrown out of the vehicle.
{WARNING:
Never do this.
Never hold an infant or a child while riding in a
vehicle. Due to crash forces, an infant or a child
will become so heavy it is not possible to hold it
during a crash. For example, in a crash at only
40 km/h (25 mph), a 5.5 kg (12 lb) infant will
suddenly become a 110 kg (240 lb) force on a
person's arms. An infant should be secured in
an appropriate restraint.
2-52

{WARNING:
Never do this.
Children who are up against, or very close to, any
airbag when it inflates can be seriously injured or
killed. Never put a rear-facing child restraint in the
right front seat. Secure a rear-facing child restraint
in a rear seat. It is also better to secure a(Continued)
WARNING: (Continued)
forward-facing child restraint in a rear seat. If you
must secure a forward-facing child restraint in the
right front seat, always move the front passenger
seat as far back as it will go.
2-53

Q: What are the different types of add-on childrestraints?
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.
{WARNING:
To reduce the risk of neck and head injury during
a crash, infants need complete support. This is
because an infant's neck is not fully developed
and its head weighs so much compared with the
rest of its body. In a crash, an infant in a
rear-facing child restraint 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
rear-facing child restraints.
2-54

{WARNING:
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. To reduce the
risk of serious or fatal injuries during a crash,
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.
2-55

A forward-facing child
seat (B) provides restraint
for the child's body with
the harness.
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.
2-56

Securing an Add-On Child Restraint in
the Vehicle
{WARNING:
A child can be seriously injured or killed in a crash
if the child restraint is not properly secured in the
vehicle. Secure the child restraint properly in the
vehicle using the vehicle's safety belt or LATCH
system, following the instructions that came with
that child restraint and the instructions in this
manual.
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. See Lower Anchors and Tethers for Children
(LATCH)
on page 2‑59for 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 the vehicle
—even when no child
is in it.
Securing the Child Within the Child
Restraint
{WARNING:
A child can be seriously injured or killed in a crash
if the child is not properly secured in the child
restraint. Secure the child properly following the
instructions that came with that child restraint.
2-57

Where to Put the Restraint
According to accident statistics, children and infants
are safer when properly restrained in a child restraint
system or infant restraint system secured in a rear
seating position.
We recommend that children and child restraints be
secured in a rear seat, including: an infant or a child
riding in a rear-facing child restraint; a child riding in a
forward-facing child seat; an older child riding in a
booster seat; and children, who are large enough,
using safety belts.
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.
{WARNING:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger airbag inflates. This is because the
back of the rear-facing child restraint would be
very close to the inflating airbag. A child in a
forward-facing child restraint can be seriously
(Continued)
WARNING: (Continued)
injured or killed if the right front passenger airbag
inflates and the passenger seat is in a forward
position.
The vehicle may have a passenger sensing
system which is designed to turn off the right front
passenger frontal airbag under certain conditions.
Even if the passenger sensing system, if
equipped, has turned off the right front passenger
frontal airbag, no system is fail-safe. No one can
guarantee that an airbag will not deploy under
some unusual circumstance, even though it is
turned off.
Secure rear-facing child restraints in a rear
seat, even if the airbag is off. 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.
