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 083.
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

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.

92 SEATS AND RESTRAINTS
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, seeLower Anchors and Tethers
for Children (LATCH System) 084 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) 084 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
Where to Put the Restraint 083.
{Warning
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 adjust the power seat when
a child restraint is installed.
Adjusting the seat may cause
damage to the installed child
restraint. Use the window lockout
button on the driver door to
prevent adjustment of the seat
whenever a child restraint is
installed.
If the rear seat is adjustable, make
sure the rear seat is positioned fully
rearward before installing a child
restraint. 1. Put the child restraint on the seat.
2. 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.

94 SEATS AND RESTRAINTS
6. If the child restraint has a toptether, follow the child restraint
manufacturer's instructions
regarding the use of the top
tether. See Lower Anchors and
Tethers for Children (LATCH
System) 084.
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 083.
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 071 and
Passenger Airbag Status Indicator 0121
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
(Continued)
Warning (Continued)
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
forward-facing child restraint in the
front outboard passenger seat,(Continued)

Warning (Continued)
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 071
for additional information.
If the child restraint uses a top tether,
see Lower Anchors and Tethers for
Children (LATCH System) 084 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 0121.
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.
Tilt the latch plate to adjust the
belt if needed.
