88 Seats and Restraints
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 seat.
Booster seats use the vehicle’s seat
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 seat
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 seat 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 Seat Belt in the Rear Seat) 094
or Securing Child Restraints (With
the Seat Belt in the Front Seat)
0 96.
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. 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) 094
or Securing Child Restraints (With
the Seat Belt in the Front Seat)
0 96.
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).

90 Seats and Restraints
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 childrestraint system or infant restraint
system secured in a rear seating
position. See
Where to Put the
Restraint 086 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 seat
belts to secure the restraint,
following 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 allowed to go all
the way back into the retractor,
but it cannot do this if it is

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 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.(Continued)
Caution (Continued)
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.
If you need to secure more than one
child restraint in the rear seat, see
Where to Put the Restraint 086.
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 seat 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 seat 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. 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” at the end
of this section.

To reinstall the head restraint:
1. Insert the head restraint postsinto the holes in the top of the
seatback. The notches on the
posts must face the driver side
of the vehicle.
2. Push the head restraint down. If necessary, press the height
adjustment release button to
further lower the head restraint.
See Head Restraints 052.
3. Try to move the head restraint to make sure 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 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) 087 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) 087 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.

Seats and Restraints 95
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 readWhere to Put
the Restraint 086.
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) 087.
2. Pick up the latch plate, and run the lap and shoulder portions
of the vehicle's seat belt
through or around the restraint.
The child restraint instructions
will show you how.
3. Push the latch plate into thebuckle until it clicks.
Position the release button on
the buckle, away from the child
restraint system, so that the
seat belt could be quickly
unbuckled if necessary.4. Pull the shoulder belt all theway out of the 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 downon 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.
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. 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) 087.
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)
087 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 086.
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 75 and Passenger Airbag Status
Indicator 0116 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.

Seats and Restraints 97
{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
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(Continued)
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) 087 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 0116.
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 seat belt
