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
(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
(Front Outboard
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 on
page 3-44.
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 on
page 3-31 andPassenger Airbag
Status Indicator on page 5-20 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.

Seats and Restraints 3-59
{Warning
A child in a rear-facing child
restraint can be seriously injured
or killed if the front outboard
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
outboard passenger airbag
inflates and the passenger seat is
in a forward position.
The vehicle may have a
passenger sensing system which
is designed to turn off the front
outboard passenger frontal airbag
under certain conditions.
Even if the passenger sensing
system, if equipped, has turned
off the front outboard passenger
frontal airbag, no system is(Continued)
Warning (Continued)
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 outboard seat, always
move the front passenger seat as
far back as it will go. It is better to
secure the child restraint in a
rear seat.
SeePassenger Sensing System
on page 3-31 for additional
information.
If the vehicle does not have a rear
seat that will accommodate a
rear-facing child restraint, a
rear-facing child restraint should not
be installed in the vehicle, even if
the airbag is off. If the child restraint has the LATCH
system, see
Lower Anchors and
Tethers for Children (LATCH
System) on page 3-46 for how and
where to install the child restraint
using LATCH. If you secure a child
restraint using a safety belt and it
uses a top tether, see Lower
Anchors and Tethers for Children
(LATCH System) on page 3-46 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.

3-60 Seats and Restraints
You will be using the lap-shoulder
belt to secure the child restraint in
this position. Follow the instructions
that came with the child restraint.
1. Move the seat as far back as itwill go before securing the
forward-facing child restraint.
When the passenger sensing
system, if equipped, has turned
off the front outboard passenger
frontal airbag, the off indicator in
the passenger airbag status
indicator should light and stay lit
when you start the vehicle. See
Passenger Airbag Status
Indicator on page 5-20.
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 through
or around the restraint. The child
restraint instructions will show
you how.
Tilt the latch plate to adjust the
belt, if needed.
4. Push the latch plate into the
buckle until it clicks.
Position the release button so
that the safety belt could be
quickly unbuckled if necessary.
