route the tether under the
head restraint and in
between the head restraint
posts.
If the position you are
using has an adjustable
head restraint and you are
using a dual tether, raise
the head restraint and
route the tether under the
head restraint and in
between the 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) 070 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) 070 for
top tether anchor locations.

SEATS AND RESTRAINTS 79
{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 057
for additional information.
If the child restraint uses a top tether,
see Lower Anchors and Tethers for
Children (LATCH System) 070 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 099.
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.
