seating position will need to be
secured using the vehicle safety
belts instead of the LATCH anchors.
Refer to the following illustration to
learn which anchors to use.
There are five lower LATCH anchors
in the rear seat.
.Use anchors 1 and 2 when
installing a child restraint using
LATCH in the right rear seating
position.
. Use anchors 3 and 4 when
installing a child restraint using
LATCH in the center rear seating
position. .
Use anchors 4 and 5 when
installing a child restraint using
LATCH in left rear seating
position.
Installing child restraints using
LATCH in the center and left rear
seating positions at the same time is
prohibited.
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. 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 safety belts. 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. For outboard rear seating positions, put the head
restraint in the upright
position. See Head
Restraints 053.
1.3. Put the child restraint on the seat.
1.4. 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,
if equipped. Refer to the child
restraint instructions and the
following steps:
2.1. Find the top tether anchor.

Open the cover to expose
the anchor.
2.2. Route, attach, and tighten the top tether according
to the child restraint
instructions and the
following instructions:
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 an adjustable
headrest or head restraint
and you are using a
single tether, raise the headrest or head restraint
and 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 your are using a dual
tether, raise the headrest
or head restraint and
route the tether under the
headrest or head restraint
and around the headrest
or head restraint posts.
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.
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 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, see
Lower Anchors and
Tethers for Children (LATCH
System) 088 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) 088 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.
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 087.
1. Put the child restraint on the seat.
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.

6. If the child restraint has a toptether, follow the child restraint
manufacturer's instructions
regarding the use of the top
tether. See Lower Anchors and
Tethers for Children (LATCH
System) 088.
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 safety 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 safety belt and
let it return to the stowed position.
If the top tether is attached to a top
tether anchor, disconnect it.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 087.
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 075 and Passenger Airbag
Status Indicator 0119 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 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

Warning (Continued)
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 75 for additional information.
If the child restraint uses a top
tether, see Lower Anchors and
Tethers for Children (LATCH
System) 088 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. 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.
When the passenger sensing
system has turned off the front
outboard passenger frontal
airbag 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 0119.
2. Put the child restraint on the seat.
3. 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.
Tilt the latch plate to adjust the
belt if needed.
