Seats and Restraints 69
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 restraint.
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.
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
and anchor.
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.

labeled with the maximum child weight,
with which the LATCH system can be used
for installing the child restraint.
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
Securing Child
Restraints (With the Seat Belt in the Rear
Seat) 076 orSecuring Child Restraints (With
the Seat Belt in the Front Seat) 078.

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 the event of 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 with a top tether are
designed for use with or without the top
tether being attached. Others require thetop 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.

72 Seats and Restraints
To assist in locating the lower anchors, each
seating position with lower anchors has two
labels, on the seatback near the crease
between the seatback and the seat cushion.
The outboard lower anchors are behind the
vertical openings in the seat trim.
To assist in locating the top tether anchors,
the top tether anchor symbol is near the
anchors.
The top tether anchors for each rear seating
position are located on the back of the rear
seatback. Be sure to use an anchor located
directly behind the seating position where
the child restraint will be placed.For models with a cargo cover, the top
tether anchors are on the back of the rear
seatbacks. Remove the cargo cover before
installing the top tether. The cargo cover
should remain off while the top tether is in
use. Be sure to use an anchor directly
behind 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.

either the LATCH anchors or the vehicle
seat belt. Follow the instructions that
came with the child restraint and the
instructions in this manual.
{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(Continued)
Warning (Continued)
allowed to go all the way back into the
retractor, but it cannot do this if it is
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 seat 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 seat belts. This may
damage these parts. If necessary, move
buckled seat belts to avoid rubbing the
LATCH attachments.
Do not fold the rear seatback when the
seat is occupied. Do not fold the empty
rear seat with a seat belt buckled. This
(Continued)
Caution (Continued)
could damage the seat belt or the seat.
Unbuckle and return the seat 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 068.
1. Attach and tighten the lower attachments to the lower anchors. If the
child restraint does not have lower
attachments or the desired seating
position does not have lower anchors,
secure the child restraint with the top
tether and the seat belt. Refer to the
child restraint manufacturer instructions
and the instructions in this manual.
1.1. Find the lower anchors for the desired seating position.
1.2. Put the child restraint on the seat. For rear outboard seating positions,
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” at the
end of this section.

Seats and Restraints 75
using a dual tether, route the
tether around the headrest or head
restraint posts.
If the child restraint is installed next
to a center seat, make sure the top
tether does not interfere with the
center seating position shoulder
belt/retractor. If it does, find
another suitable seating position to
install the child 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 second row outboard head restraints
can be removed if they interfere with the
proper installation of the child restraint.
To remove the second row head restraint:
1. Partially fold the seatback forward. See Rear Seats 043 for additional
information.
2. Press both buttons on the head restraint posts at the same time, and pull up on
the head restraint.
3. Store the head restraint in a secure place.
4. When the child restraint is removed, reinstall the head restraint before the
seating position is used.
{Warning
With head restraints that are not
installed and adjusted properly, there is a
greater chance that occupants will suffer
a neck/spinal injury in a crash. Do not

3. Try to move the head restraint to makesure that it is locked in place.
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 (With
the Seat Belt in the Rear Seat)
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.
If the child restraint has the LATCH system,
see Lower Anchors and Tethers for Children
(LATCH System) 069 for how and where to
install the child restraint using LATCH. If a
child restraint is secured in the vehicle using
a seat belt and it uses a top tether, see
Lower Anchors and Tethers for Children
(LATCH System) 069 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. Refer to the
instructions that came with the child
restraint and see Lower Anchors and Tethers
for Children (LATCH System) 069
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 seat 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
068.
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" under Lower Anchors and
Tethers for Children (LATCH System)
0 69.
2. Pick up the latch plate and run the lap and shoulder portions of the vehicle seat
belt through or around the child
restraint. Ensure the seat belt webbing is
routed as directly as possible and is not
caught on seat handles or plastic trim.
The child restraint instructions will show
you how.

6. If the child restraint has a top tether,follow the child restraint manufacturer's
instructions regarding the use of the top
tether. See Lower Anchors and Tethers
for Children (LATCH System) 069.
7. Before placing a child in the child restraint, make sure it is securely held in
place. To check, grasp the child restraint
at the seat belt path and attempt to
move it side to side and back and forth.
When the child restraint is properly
installed, there should be no more than
2.5 cm (1 in) of movement.
To remove the child restraint, unbuckle the
vehicle seat belt and let it return to the
stowed position. If the top tether is attached
to a top tether anchor, disconnect it.
If the head restraint was removed, reinstall
it before the seating position is used. See
"Head Restraint Removal and Reinstallation"
underLower Anchors and Tethers for Children
(LATCH System) 069 for additional
information on installing the head restraint
properly.Securing Child Restraints (With
the Seat 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
0 68.
In addition, the vehicle has a passenger
sensing system which is designed to turn off
the front outboard passenger frontal and
knee airbag under certain conditions. See
Passenger Sensing System 058 and
Passenger Airbag Status Indicator 0101 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
(Continued)
Warning (Continued)
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
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 058 for
additional information.
If the child restraint uses a top tether, see
Lower Anchors and Tethers for Children
(LATCH System) 069 for top tether anchor
locations.

Seats and Restraints 79
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
tether must be anchored.
In Canada, the law requires that
forward-facing child restraints have a top
tether, and that the tether be attached.
When using the lap-shoulder belt to secure
the child restraint in this position, follow the
instructions that came with the child
restraint and the following instructions:1. Move the seat as far back as it will go before securing the forward-facing child
restraint. Move the seat upward or the
seatback to an upright position,
if needed, to get a tight installation of
the child restraint.
There must be finger clearance between
the release pushbutton and the child
restraint.
When the passenger sensing system has
turned off the front outboard passenger
frontal and knee airbag, the off indicator
on the passenger airbag status indicator
should light and stay lit when you start
the vehicle. See Passenger Airbag Status
Indicator 0101. 2. Put the child restraint on the seat.
3. Pick up the latch plate and run the lap
and shoulder portions of the vehicle seat
belt through or around the restraint.
Ensure the seat belt webbing is routed
as direct as possible and is not caught
on seat handles or plastic trim. The child
restraint instructions will show you how.
4. Push the latch plate into the buckle untilit clicks.
Position the release pushbutton on the
buckle, away from the child restraint, so
that the seat belt could be quickly
unbuckled if necessary.
5. Pull the shoulder belt all the way out ofthe retractor to set the lock. When the
retractor lock is set, the belt can be
tightened but not pulled out of the
retractor.

6. To tighten the belt, push down on thechild restraint, pull the shoulder portion
of the belt to tighten the lap portion of
the belt, and feed the shoulder belt back
into the retractor.
There must be finger clearance between
the release pushbutton and the child
restraint. If there is not clearance
between the buckle release pushbutton
and the child restraint, move the seat
upward and repeat prior installation
steps. Otherwise secure the child
restraint in a rear seat.
When installing a forward-facing child
restraint, it may be helpful to use your
knee to push down on the child restraint
as you tighten the belt. Try to pull the belt out of the retractor
to make sure the retractor is locked.
If the retractor is not locked, repeat
Steps 5 and 6.
7. Before placing a child in the child restraint, make sure it is securely held in
place. To check, grasp the child restraint
at the seat belt path and attempt to
move it side to side and back and forth.
When the child restraint is properly
installed, there should be no more than
2.5 cm (1 in) of movement.
If the airbags are off, the off indicator in the
passenger airbag status indicator will come
on and stay on when the vehicle is started.
If a child restraint has been installed and
the on indicator is lit, see “If the On
Indicator Is Lit for a Child Restraint” under
Passenger Sensing System 058.
To remove the child restraint, unbuckle the
vehicle seat belt and let it return to the
stowed position.
