SEATS AND RESTRAINTS 65
{Warning
A child in a rear-facing child
restraint can be seriously injured or
killed if the front passenger 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 passenger airbag
inflates and the passenger seat is in
a forward position.
Even if the passenger sensing
system has turned off the 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 front seat,
always move the front passenger(Continued)
Warning (Continued)
seat as far back as it will go. It is
better to secure the child restraint
in a rear seat.
SeePassenger Sensing System 053
for additional information.
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.
Child restraints and booster seats vary
considerably in size, and some may fit
in certain seating positions better
than others. Do not install a child
restraint in any rear seating position
where it cannot be installed securely.
Depending on where you place the
child restraint and the size of the
child restraint, you may not be able to
access adjacent seat belts or LATCH
anchors for additional passengers or
child restraints. Adjacent seating
positions should not be used if the
child restraint prevents access to or
interferes with the routing of the
seat belt. The seat in front of an installed child
restraint should be adjusted to ensure
proper installation according to the
child restraint manual.
Wherever a child restraint is installed,
be sure to follow the instructions that
came with the child restraint and
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
the vehicle
—even when no child is
in it.
Lower Anchors and
Tethers for Children
(LATCH System)
The LATCH system secures a child
restraint during driving or in a crash.
LATCH attachments on the child
restraint are used to attach the child
restraint to the anchors in the vehicle.
The LATCH system is designed to
make installation of a child restraint
easier.

5. To tighten the belt, push down onthe 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) 065.
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) 065 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 064.
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 053 and
Passenger Airbag Status Indicator 096
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.

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
forward-facing child restraint in the(Continued)
Warning (Continued)
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 053
for additional information.
If the child restraint uses a top tether,
see Lower Anchors and Tethers for
Children (LATCH System) 065 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.
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
096.
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 child restraint. The child
restraint instructions will show
you how.
