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

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
(Continued)
Warning (Continued)
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(Continued)
Warning (Continued)
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.

The power seats will work
with the ignition off. Children
could operate the power
seats and be injured. Never
leave children alone in the
vehicle.
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.
If you need to secure more
than one child restraint in the
rear seat, see Where to Put
the Restraint 079.
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.
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, adjust the top
tether to its full length and
attach it to the anchor.
Refer to the child restraint
instructions and the
following steps:
2.1. Find the top tether anchor. 2.2. Open the top tether
anchor cover to expose
the anchor.
2.3.Route, attach, and tighten the top tether
according to your child

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, adjust itaccordingly to allow
proper fitment. If you
are using a single
tether, route the tether
in between the
headrest or head
restraint posts.
If the position you are
using has an adjustable
headrest or head
restraint, adjust it
accordingly to allow
proper fitment. If you
are using a dual tether,
route the tether in
between 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
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)
080
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) 080 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

1. Put the child restraint on the seat.
If the head restraint
interferes with the proper
installation of the child
restraint, see your dealer
for assistance.
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.

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) 080.
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.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 079.
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 66 and
Passenger Airbag Status
Indicator 0117 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 airbag(s), no
system is fail-safe. No one
can guarantee that an
airbag will not deploy under

Warning (Continued)
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.
See Passenger Sensing
System066 for additional
information.
If the child restraint uses a top
tether, see Lower Anchors
and Tethers for Children
(LATCH System) 080 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.
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 push button and 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
0117.
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.

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
0 66.
To remove the child restraint,
unbuckle the vehicle seat belt
and let it return to the stowed
position.
