3-44 Seats and Restraints
{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.
{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.
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.

Seats and Restraints 3-45
{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.

Seats and Restraints 3-47
{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.
{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 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.

3-48 Seats and Restraints
(B) Forward-Facing Child Seat
A forward-facing child seat (B)
provides restraint for the child's
body with the harness.(C) Booster Seats
A booster seat (C) 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
{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.

Seats and Restraints 3-49
SeeLower Anchors and Tethers for
Children (LATCH System)on
page 3‑51for more information.
Children 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.
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.

Lower Anchors and
Tethers for Children
(LATCH System)
The LATCH system holds a child
restraint during driving or in a crash.
This system is designed to make
installation of a child restraint easier.
The LATCH system uses anchors in
the vehicle and attachments on the
child restraint that are made for use
with the LATCH system.
Make sure that a LATCH-compatible
child restraint is properly installed
using the anchors, or use the
vehicle's safety belts to secure the
restraint, following the instructions
that came with that restraint, and
also the instructions in this manual.When installing a child restraint
with a top tether, you must also
use either the lower anchors or the
safety belts to properly secure the
child restraint. A child restraint must
never be installed using only the top
tether and anchor.
In order to use the LATCH
system in the vehicle, you need
a child restraint that has LATCH
attachments. The child restraint
manufacturer will provide you
with instructions on how to use the
child restraint and its attachments.
The following explains how to
attach a child restraint with these
attachments in the vehicle.
Not all vehicle seating positions or
child restraints have lower anchors
and attachments or top tether
anchors and attachments.Lower Anchors
Lower anchors (A) are metal bars
built into the vehicle. There are
two lower anchors for each
LATCH seating position that will
accommodate a child restraint
with lower attachments (B).

3-54 Seats and Restraints
Securing a Child Restraint
Designed for the LATCH System
{WARNING
If a LATCH-type child restraint is
not attached to anchors, the child
restraint will not be able to protect
the child correctly. In a crash, the
child could be seriously injured
or killed. Install a LATCH-type
child restraint properly using the
anchors, or use the vehicle's
safety belts to secure the
restraint, following the instructions
that came with the child restraint
and the instructions in this
manual.
{WARNING
Do not attach more than one child
restraint to a single anchor.
Attaching more than one child
restraint to a single anchor could
cause the anchor or attachment
to come loose or even break
during a crash. A child or others
could be injured. To reduce the
risk of serious or fatal injuries
during a crash, attach only
one child restraint per anchor.
{WARNING
Children can be seriously injured
or strangled if a shoulder belt is
wrapped around their neck and
the safety belt continues to
tighten. Buckle any unused safety
belts behind the child restraint
so children cannot reach them.(Continued)
WARNING (Continued)
Pull the shoulder belt all the way
out of the retractor to set the lock,
if your vehicle has one, after the
child restraint has been installed.
Notice: Do not let the LATCH
attachments rub against the
vehicle’ s safety belts. This may
damage these parts. If necessary,
move buckled safety belts to
avoid rubbing the LATCH
attachments.
Do not fold the empty rear seat
with a safety belt buckled. This
could damage the safety belt or
the seat. Unbuckle and return the
safety belt to its stowed position,
before folding the seat.

Replacing LATCH System
Parts After a Crash
{WARNING
A crash can damage the LATCH
system in the vehicle. A damaged
LATCH system may not properly
secure the child restraint,
resulting in serious injury or even
death in a crash. To help make
sure the LATCH system is
working properly after a crash,
see your dealer to have the
system inspected and any
necessary replacements made
as soon as possible.
If the vehicle has the LATCH system
and it was being used during a
crash, new LATCH system parts
may be needed.
New parts and repairs may be
necessary even if the LATCH
system was not being used at the
time of the crash.
Securing Child Restraints
(Rear Outboard Seating
Position)
When securing a child restraint in
a rear seating position, study the
instructions that came with the
child restraint to make sure it is
compatible with this vehicle.
If the child restraint has the LATCH
system, see Lower Anchors and
Tethers for Children (LATCH
System)
on page 3‑51for how and
where to install the child restraint
using LATCH. If a child restraint is
secured in the vehicle using a
safety belt and it uses a top tether,
see Lower Anchors and Tethers for
Children (LATCH System)
on
page 3‑51for top tether anchor
locations. Do not secure a child seat in a
position without a top tether anchor
if a national or local law requires
that the top tether be anchored, or if
the instructions that come with the
child restraint say that the top strap
must be anchored.
In Canada, the law requires that
forward-facing child restraints have
a top tether, and that the tether be
attached.
If the child restraint does not have
the LATCH system, you will be
using the safety belt to secure
the child restraint in this position.
Be sure to follow the instructions
that came with the child restraint.
Secure the child in the child restraint
when and as the instructions say.
