Seats and Restraints 85
Wherever a child restraint is
installed, be sure to follow the
instructions that came with the child
restraint system and secure the
child restraint system 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. The LATCH 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 safety belts. Do not
use both the safety belts and the
LATCH anchorage system to secure
a rear-facing or forward-facing
child seat.
Booster seats use the vehicle’s
safety belts to secure the child in
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.
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. The LATCH anchorage system can
be used until the combined weight
of the child plus the child restraint is
29.5 kg (65 lbs). Use the safety belt
alone instead of the LATCH
anchorage system once the
combined weight is more than
29.5 kg (65 lbs).
See
Securing Child Restraints (With
the Safety Belt in the Rear Seat)
0 92 orSecuring Child Restraints
(With the Safety Belt in the Front
Seat) 094.
Child restraints built after March
2014 will be labeled with the
specific child weight up to which the
LATCH system can be used to
install the restraint.
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.

(With the Safety Belt in the Front
Seat) 094.
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) anchors the top of
the child restraint to the vehicle.
A top tether anchor is built into the
vehicle. The top tether
attachment (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 (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 the child
restraint.

Seats and Restraints 87
H:Seating positions with two
lower anchors.
To assist in locating the lower
anchors, each rear anchor position
has a label, near the crease
between the seatback and the seat
cushion.
To assist in locating the top tether
anchors, the top tether anchor
symbol is on the cover.
The top tether anchors are under
the covers, behind the rear seat, on
the filler panel. Be sure to use an
anchor 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. See
Where to Put the
Restraint 084 for additional
information.
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.

88 Seats and Restraints
{Warning
To reduce the risk of serious or
fatal injuries during a crash, 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.
{Warning
Children can be seriously injured
or strangled if a shoulder belt is
wrapped around their neck. The
shoulder belt can tighten but
cannot be loosened if it is locked.
The shoulder belt locks when it is
pulled all the way out of the
retractor. It unlocks when the
shoulder belt is allowed to go all
the way back into the retractor,
but it cannot do this if it is(Continued)
Warning (Continued)
wrapped around a child’s neck.
If the shoulder belt is locked and
tightened around a child’s neck,
the only way to loosen the belt is
to cut it.
Buckle any unused safety belts
behind the child restraint so
children cannot reach them. Pull
the shoulder belt all the way out
of the retractor to set the lock,
and tighten the belt behind the
child restraint after the child
restraint has been installed.
Caution
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.
(Continued)
Caution (Continued)
Do not fold the rear seatback
when the seat is occupied. 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.
If you need to secure more than one
child restraint in the rear seat, see
Where to Put the Restraint 084.
Make sure to attach the child
restraint at the proper anchor
location.
This system is designed to make
installation of child restraints easier.
When using lower anchors, do not
use the vehicle's safety belts.
Instead use the vehicle's anchors
and child restraint attachments to
secure the restraints. Some
restraints also use another vehicle
anchor to secure a top tether.

90 Seats and Restraints
If the position you are
using does not have a
headrest or head
restraint, or the headrest
or head restraint has
been removed, and you
are using a dual tether,
route the tether over the
seatback.
If the position you are
using has an adjustable
headrest or head restraint
and you are using a
single tether, route the
tether under the headrest
or head restraint and in
between the headrest or
head restraint posts.
If the position you are
using has an adjustable
headrest or head restraint
and you are using a dual
tether, route the tether
around the headrest or
head restraint.
3. Before placing a child in the child restraint, make sure it is
securely held in place. To
check, grasp the child restraint
at the LATCH path and attempt
to move it side to side and
back and forth. There should
be no more than 2.5 cm (1 in) of
movement, for proper
installation.
Head Restraint Removal and
Reinstallation
The rear outboard head restraints
can be removed if they interfere with
the proper installation of the child
restraint.
To remove the head restraint:
1. Partially fold the seatback forward. See Rear Seats056
for additional information.
2. Press both buttons on the head restraint posts at the same
time, and pull up on the head
restraint.

Securing Child Restraints
(With the Safety Belt in
the Rear Seat)
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, seeLower Anchors and
Tethers for Children (LATCH
System) 085 for 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) 085 for
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 or vehicle seat
position does not have the LATCH
system, you will be using the safety
belt to secure the child restraint.
Be sure to follow the instructions
that came with the child restraint.
If more than one child restraint
needs to be installed in the rear
seat, be sure to read
Where to Put
the Restraint 084.
1. Put the child restraint on the seat.
If the head restraint interferes
with the proper installation of
the child restraint, the head
restraint may be removed. See
“Head Restraint Removal and
Reinstallation” underLower
Anchors and Tethers for
Children (LATCH System) 085.
2. Pick up the latch plate, and run the lap and shoulder portions
of the vehicle's safety belt through or around the restraint.
The child restraint instructions
will show you how.
3. Push the latch plate into the
buckle until it clicks.
Position the release button on
the buckle, away from the child
restraint system, so that the
safety belt could be quickly
unbuckled if necessary.

and Tethers for Children (LATCH
System) 085 for additional
information on installing the head
restraint properly.
Securing Child Restraints
(With the Safety Belt in
the Front Seat)
This vehicle has airbags. A rear
seat is a safer place to secure a
forward-facing child restraint. See
Where to Put the Restraint 084.
In addition, the vehicle has a
passenger sensing system which is
designed to turn off the front
outboard passenger frontal airbag
and knee airbag under certain
conditions.
See Passenger Sensing System
0 72 and Passenger Airbag Status
Indicator 0113 for more information,
including important safety
information. 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 front outboard
passenger frontal 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
outboard passenger frontal airbag
inflates and the passenger seat is
in a forward position.
Even if the passenger sensing
system has turned off the front
outboard passenger airbag(s), no
system is fail-safe. No one can
guarantee that an airbag will not
(Continued)
Warning (Continued)
deploy under some unusual
circumstance, even though the
airbag(s) are off.
Secure rear-facing child restraints
in a rear seat, even if the
airbag(s) are off. If you secure a
forward-facing child restraint in
the front outboard passenger
seat, always move the seat as far
back as it will go. It is better to
secure the child restraint in a
rear seat.
SeePassenger Sensing System
0 72 for additional information.
If the child restraint uses a top
tether, see Lower Anchors and
Tethers for Children (LATCH
System) 085 for 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
