Where to Put the Restraint
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.
We recommend that children and child restraints be
secured in a rear seat, including: an infant or a
child riding in a rear-facing child restraint; a child riding
in a forward-facing child seat; an older child riding in
a booster seat; and children, who are large enough,
using safety belts.
A label on your sun visor says, “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.
{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.
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 1-70for
additional information.

{CAUTION:
A child in a child restraint in the center front seat
can be badly injured or killed by the frontal airbags
if they inate. Never secure a child restraint in the
center front seat. It is always better to secure a
child restraint in a rear seat.
Do not use child restraints in the center front seat
position.
When securing a child restraint in a rear seating
position, study the instructions that came with your 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 your vehicle — even when no child
is in it.
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 your 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 your vehicle.
Not all vehicle seating positions or child restraints have
lower anchors and attachments or top tether anchors
and attachments.
1-49

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.
Your 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.
1-50

The top tether anchors are located on the back of the
rear seat frame above the oor for each rear seating
position. Fold down the rear seatback(s) to access the
anchors. SeeRear Seat Operation on page 1-13.
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 1-48for 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.
1-52

{CAUTION:
If either seatback is not locked, it could move
forward in a sudden stop or crash. That could
cause injury to the person sitting there. Always
push and pull on the seatbacks to be sure they
are locked.
1.5. Lift the seatback up and push it rearward.
Then lower the seat cushion until the
seatback and the seat cushion lock into
position.2. Attach 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 your child restraint manufacturer instructions and
the instructions in this manual.
2.1. Find the lower anchors for the desired
seating position.
2.2. Put the child restraint on the seat.
2.3. Attach and tighten the lower attachments on
the child restraint to the lower anchors.
3. Tighten the top tether.
4. Push and pull the child restraint in different
directions to be sure it is secure.

Securing a Child Restraint in a Rear
Seat Position
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) on
page 1-49for how and where to install the child restraint
using LATCH. If you secure a child restraint using a
safety belt and it uses a top tether, seeLower Anchors
and Tethers for Children (LATCH) on page 1-49for
top tether anchor locations.
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 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 1-48.
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 seeLower Anchors and
Tethers for Children (LATCH) on page 1-49.
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.
1-56

5. To tighten the belt, push down on the child 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.
If the child restraint has a top tether, follow the child
restraint manufacturer’s instructions regarding the
use of the top tether. SeeLower Anchors and
Tethers for Children (LATCH) on page 1-49.
6. Push and pull the child restraint in different
directions to be sure it is secure.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 a Child Restraint in the
Center Front Seat Position
{CAUTION:
A child in a child restraint in the center front seat
can be badly injured or killed by the frontal airbags
if they inate. Never secure a child restraint in the
center front seat. It is always better to secure a
child restraint in a rear seat.
Do not use child restraints in the center front seat
position.
1-58

Securing a Child Restraint in the
Right Front Seat Position
This vehicle has airbags. A rear seat is a safer place to
secure a forward-facing child restraint. SeeWhere to
Put the Restraint on page 1-48.
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 1-70andPassenger Airbag
Status Indicator on page 3-33for more information,
including important safety information.
A label on the sun visor says, “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.
{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.
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.
