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 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 with top tethers 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.

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 076 for
additional information.
Securing a Child Restraint Designed for
the LATCH System
{Warning
A child could be seriously injured or killed
in a crash if the child restraint is not
properly attached to the vehicle using
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.

82 Seats and Restraints
{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
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
could damage the seat belt or the seat.
Unbuckle and return the seat belt to its
stowed position, before folding the seat.
The vehicle is equipped with a front center
airbag in the inboard side of the driver seat.
Even with a front center airbag, a child
restraint can be installed in any second row
seating position.
If you need to secure more than one child
restraint in the rear seat, see Where to Put
the Restraint 076.
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 seat
belt and top tether when recommended by the child restraint manufacturer. Refer
to your 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.
1.3. Attach and tighten the lower attachments on the child restraint
to the lower anchors.
2. If the child restraint manufacturer recommends that the top tether be
attached, attach and tighten the top
tether to the top tether anchor. Refer to
the child restraint instructions and the
following steps:
2.1. Find the top tether anchor.
2.2. Route, attach, and tighten the top tether according to your child
restraint instructions and the
following instructions:

Seats and Restraints 83
If the position you are using does
not have a headrest or head
restraint and you are using a single
tether, route the tether over the
seatback.
If the position you are using does
not have a headrest or head
restraint and you are using a dual
tether, route the tether over the
seatback.
If the position you are using has a
fixed headrest or head restraint and
you are using a single tether, route
the tether around the inboard side
of the headrest or head restraint.
If the position you are using has a
fixed or an adjustable head restraint
and you are using a dual tether,
route the tether around the 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.
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.

84 Seats and Restraints
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)
The vehicle may be equipped with a front
center airbag in the inboard side of the
driver seat. Even with a front center airbag,
a child restraint can be installed in any
second row seating position. If you install a
child restraint in a second row center seat,
move the second row seat to the rearward
position, whenever possible, to minimize
contact with the front center airbag.
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,
seeLower Anchors and Tethers for Children
(LATCH System) 077 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)
077 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
tether 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 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 076.
If the child restraint manufacturer
recommends using a top tether, attach and
tighten the top tether to the top tether
anchor. Refer to the instructions that came
with the child restraint and see Lower
Anchors and Tethers for Children (LATCH
System) 077. 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) 077.
2. Pick up the latch plate, and run the lap and shoulder portions of the vehicle seat
belt through or around the child
restraint. The child restraint instructions
will show you how.
3. Push the latch plate into the buckle untilit clicks.

Position the release button on the
buckle, away from the child restraint, so
that the seat belt could be quickly
unbuckled if necessary.
4. 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.
5. 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. 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 4 and 5.
6. For forward-facing child restraints, attach and tighten the top tether to the top
tether anchor (loop). Refer to the child
restraint instructions, the vehicle LATCH anchor weight limits, and instructions
listed in
Lower Anchors and Tethers for
Children (LATCH System) 077.
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"
under Lower Anchors and Tethers for
Children (LATCH System) 077 for additional
information on installing the head restraint
properly.
