3. Tighten the top tether per thechild restraint manufacturer's
instructions.
When the top tether is properly
tightened, the anchor (loop)
may bend. This is normal and
will not damage the vehicle.
If child restraints are installed
in both outboard positions, both
top tethers can be attached to
the center loop. Top tethers
can be attached for child
restraints in all three rear
seating positions at the same
time, following the routing
instructions above.
4. 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.Headrest Removal and
Reinstallation
Removing Rear Headrests
For outboard rear seating positions,
if the child restraint cannot be
installed properly with the headrest
in place, the headrest may be
removed. See your dealer for
assistance with removal, and store
the removed headrests in a secure
place. When the child restraint is
removed, reinstall the headrest
before the seating position is used.
Reinstalling Rear Headrests
To reinstall the headrest:
1. Insert the headrest posts into the holes in the top of the
seatback with the longer
chrome plated post toward the
driver side of the vehicle.
2. Push the headrest all the way down until it contacts the top of
the seatback.
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 Safety Belt in
the Rear Seat)
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
System) 088 for how and where to
install the child restraint using
LATCH. If a child restraint is secured
in the vehicle using a safety belt
and it uses a top tether, see Lower
Anchors and Tethers for Children
(LATCH System) 088 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.
If the child restraint or vehicle seat
position does not have the LATCH
system, you will be using the safety
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
Where to Put
the Restraint 087.

1. Remove the headrest prior to
installing a forward-facing child
restraint in an outboard rear

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 safety belt

The child restraint instructions
will show you how.

retractor to make sure the
retractor is locked. If the
retractor is not locked, repeat
Steps 5 and 6. 7. For forward-facing child
restraints, attach and tighten

anchor (loop). Refer to the child
restraint instructions, the
vehicle LATCH anchor weight
limits and instructions listed in
Lower Anchors and Tethers for
Children (LATCH System) 088.
8. Before placing a child in the child restraint, make sure it is
securely held in place. To
check, grasp the child restraint
at the safety belt path and

Securing Child Restraints
(With the Safety Belt in
the Center Front Seat)
{Warning
A child in a child restraint in the
center front seat can be badly
injured or killed by the frontal
airbags if they inflate. 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.
Securing Child Restraints
(With the Safety Belt in
the Front
Passenger Seat)
With Passenger Sensing
System
This vehicle has airbags. A rear
seat is a safer place to secure a
forward-facing child restraint. See
Where to Put the Restraint 087.
In addition, the vehicle may have a
passenger sensing system which is
designed to turn off the front
outboard passenger frontal airbag
under certain conditions. See
Passenger Sensing System 075
and Passenger Airbag Status
Indicator 0132 for more information
on this, 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.
