seat; an older child riding in a booster
seat; and children, who are large
enough, using safety belts.
A label on the sun visor says, “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.
{CAUTION
A child in a rear-facing child
restraint can be seriously injured or
killed if the right front passenger
airbag inates. This is because
the back of the rear-facing child
restraint would be very close to
the inating airbag. A child in a
forward-facing child restraint can
be seriously injured or killed if the
right front passenger airbag
inates and the passenger seat
is in a forward position.
(Continued)
CAUTION (Continued)
Even if the passenger sensing
system 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.
SeePassenger Sensing System
on page 1-54for additional
information.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.
Wherever a child restraint is
installed, be sure to 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.
Seats and Restraint System 1-33

Lower Anchors and
Tethers for Children
(LATCH)
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).Top Tether Anchor
A top tether (A, C) anchors the
top of the child restraint to the
vehicle. A top tether anchor is built
into the vehicle. The top tether
attachment (B) 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 (A) or a dual
tether (C). Either will have a
single attachment (B) to secure
the top tether to the anchor.
1-34 Seats and Restraint System

For H3T models, the top tether
anchors are located on the back
panel behind each rear seating
position. Be sure to use an anchor
located on the same side of the
vehicle as the seating position where
the child restraint will be placed.For H3 models, the top tether
anchors are located on the back of
the rear seatbacks. Be sure to use
an anchor located on the same side
of the vehicle as the seating position
where the child restraint will be
placed.
Do not secure a child restraint in a
position without a top tether anchor if
a national or local law requires that
the top tether be attached, or if the
instructions that come with the child
restraint say that the top tether must
be attached.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.
SeeWhere to Put the Restraint on
page 1-32for additional information.
Securing a Child Restraint
Designed for the LATCH System
{CAUTION
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. H3TH3

instructions that came with the
child restraint to make sure
it is compatible with this vehicle.
If the child restraint has the LATCH
system, seeLower Anchors and
Tethers for Children (LATCH) on
page 1-34for 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, seeLower
Anchors and Tethers for Children
(LATCH) on page 1-34for 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.If more than one child restraint
needs to be installed in the
rear seat, be sure to readWhere to
Put the Restraint on page 1-32.
1. Put the child restraint on the seat.
2. Pick up the latch plate, and
run the lap and shoulder portions

headrest has been removed, reinsert
in onto the seatback.Securing a Child
Restraint in the Center
Rear Seat Position
Many child restraints are too wide to
be correctly secured in the center
rear seat, although some of
them will t there. If the center seat
position is too narrow for the
child restraint, secure it in a rear
outside seat position.
If a child restraint is secured in the
center seat position, follow the
instructions inSecuring a Child
Restraint in a Rear Outside Seat
Position on page 1-41.
Securing a Child
Restraint in the Right
Front Seat Position
The vehicle has airbags. A rear
seat is a safer place to secure
a forward-facing child restraint.
SeeWhere to Put the Restraint
on page 1-32.
In addition, the vehicle has a
passenger sensing system which is
designed to turn off the right
front passenger frontal airbag under
certain conditions. SeePassenger
Sensing System on page 1-54
andPassenger Airbag Status
Indicator on page 3-26for more
information, including important
safety information.
