88 Seats and Restraints
{Warning
A young child's hip bones are still
so small that the vehicle seat 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 an
appropriate child restraint.
Child Restraint Systems
Rear-Facing Infant Restraint
A rear-facing child restraint 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.
Forward-Facing Child Restraint
A forward-facing child restraint
provides restraint for the child's
body with the harness.

Seats and Restraints 89
Booster Seats
A belt-positioning booster seat is
used for children who have
outgrown their forward-facing child
restraint. Boosters are designed to
improve the fit of the vehicle's seat
belt system until the child is large
enough for the vehicle seat belts to
fit properly without a booster seat.
See the seat belt fit test in Older
Children 084.
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 seat 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 restraints 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
System) 091 for 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 following:
1. Instruction labels provided on the child restraint
2. Instruction manual provided with the child restraint
3. This vehicle owner's 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.
In some areas Certified Child
Passenger Safety Technicians
(CPSTs) are available to inspect
and demonstrate how to correctly
use and install child restraints. In
the U.S., refer to the National
Highway Traffic Safety
Administration (NHTSA) website to
locate the nearest child safety seat

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 an appropriate
child restraint secured in a rear
seating position.
Whenever possible, children aged
12 and under should be secured in
a rear seating position.Never put a rear-facing child
restraint 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 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 injured or killed if the
front passenger airbag inflates
and the passenger seat is in a
forward position.
Even if the passenger sensing
system has turned off the 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.
(Continued)
Warning (Continued)
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 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.
SeePassenger Sensing System
0 77 for additional information.
{Warning
A child in a child restraint in the
center front seat can be badly
injured or killed by the frontal
airbags if they inflate. Never
secure a child restraint in the
center front seat. It is always
better to secure a child restraint in
a rear seat.
Do not use child restraints in the
center front seat position.

Mexico-13337776) - 2020 - CRC - 8/27/19
Seats and Restraints 91
If the vehicle does not have a rear
seat that will accommodate a
rear-facing child restraint, a
rear-facing child restraint should not
be installed in the vehicle, even if
the airbag is off.
When securing a child restraint with
the seat belts in a rear seat position,
study the instructions that came with
the child restraint to make sure it is
compatible with this vehicle.
Child restraints and booster seats
vary considerably in size, and some
may fit in certain seating positions
better than others.
Depending on where you place the
child restraint and the size of the
child restraint, you may not be able
to access adjacent seat belts or
LATCH anchors for additional
passengers or child restraints.
Adjacent seating positions should
not be used if the child restraint
prevents access to or interferes with
the routing of the seat belt.Wherever a child restraint is
installed, be sure to follow the
instructions that came with the child
restraint and secure the child
restraint properly.
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.
Lower Anchors and
Tethers for Children
(LATCH System)
The LATCH system secures a child
restraint during driving or in a crash.
LATCH attachments on the child
restraint are used to attach the child
restraint to the anchors in the
vehicle. This system is designed to
make installation of a child restraint
easier. In order to use the LATCH system in
your vehicle, you need a child
restraint that has LATCH
attachments. LATCH-compatible
rear-facing and forward-facing child
seats can be properly installed
using either the LATCH anchors or
the vehicle’
s seat belts. Do not use
both the seat belts and the LATCH
anchorage system to secure a
rear-facing or forward-facing
child seat.
Booster seats use the vehicle’s seat
belts to secure the child and the
booster seat. If the manufacturer
recommends that the booster seat
be secured with the LATCH system,
this can be done as long as the
booster seat can be positioned
properly and there is no interference
with the proper positioning of the
lap-shoulder belt on the child.
Make sure to follow the instructions
that came with the child restraint,
and also the instructions in this
manual.

92 Seats and Restraints
When installing a child restraint with
a top tether, you must also use
either the lower anchors or the seat
belts to properly secure the child
restraint. A child restraint must
never be installed using only the top
tether.
For a forward-facing 5-pt harness
child restraint where the combined
weight of the child and restraint are
up to 29.5 kg (65 lb), use either the
lower LATCH anchorages with the
top tether anchorage, or the seat
belt with the top tether anchorage.
Where the combined weight of the
child and restraint are greater than
29.5 kg (65 lb), use the seat belt with
the top tether anchorage only.

The following explains how to attach
a child restraint with these
attachments in the vehicle.
Not all vehicle seating positions
have lower anchors. In this case,
the seat belt must be used (with top tether where available) to secure
the child restraint. See

Lower Anchors
Lower anchors (1) 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 (2).
Top Tether Anchor
A top tether (3, 4) is used to secure
the top of the child restraint to the
vehicle. A top tether anchor is built
into the vehicle. The top tether
attachment hook (2) on the child
restraint connects to the top tether
anchor in the vehicle in order to
reduce the forward movement and
rotation of the child restraint during
driving or in a crash.
The child restraint may have a
single tether (3) or a dual tether (4).
Either will have a single attachment
hook (2) to secure the top tether to
the anchor.Some child restraints that have a
top tether are designed for use with
or without the top tether being
attached. Others require the top
tether always to be attached. In
Canada, the law requires that
forward-facing child restraints have
a top tether, and that the tether be
attached. Be sure to read and follow
the instructions for your child
restraint.
