Seats and Restraints 101Warning (Continued)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
(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, see Lower Anchors and
Tethers for Children (LATCH
System) 0 95 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) 0 95 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 in
this position. Be sure to follow the
instructions that came with the child restraint. Secure the child in the
child restraint when and as the
instructions say.
If more than one child restraint
needs to be installed in the rear
seat, be sure to read Where to Put
the Restraint 0 94 .
1. Put the child restraint on
the seat.
2. Pick up the latch plate, and run
the lap and shoulder portions
of the vehicle's safety belt
through or around the restraint.
The child restraint instructions
will show you how.

102 Seats and Restraints 3. Push the latch plate into the
buckle until it clicks.
Position the release button on
the buckle so that the safety
belt could be quickly unbuckled
if necessary.
4. Pull the shoulder belt all the
way out of the retractor to set
the lock. When the retractor
lock is set, the belt can be
tightened but not pulled out of
the retractor. 5. To tighten the belt, push down
on the 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) 0 95 .
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 safety 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 safety belt and
let it return to the stowed position.
If the top tether is attached to a top
tether anchor, disconnect it.

Seats and Restraints 103
Securing Child Restraints
(Front Passenger 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 0 94 .
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 82 and Passenger Airbag
Status Indicator 0 130 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.
(Continued) Warning (Continued) 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
inflate 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, always move the seat as far
(Continued) Warning (Continued) back as it will go. It is better to
secure the child restraint in a
rear seat.
See Passenger Sensing System
0 82 for additional information.
If the child restraint uses a top
tether, see Lower Anchors and
Tethers for Children (LATCH
System) 0 95 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.

104 Seats and Restraints 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.
When the passenger sensing
system has turned off the front
outboard passenger frontal
airbag and knee airbag, the off

airbag status indicator should
light and stay lit when the
vehicle is started. See
Passenger Airbag Status
Indicator 0 130 .
2. Put the child restraint on

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 safety belt path and
attempt to move it side to side
and back and forth. When the
