How the Occupant Classification Module (OCM)
Works
The Occupant Classification Module (OCM) is located
beneath the passenger seat.. The OCM classifies the
occupant into one of three size categories based on the
input from the Bladder Assembly and a Belt Tension
Sensor. The size categories include empty, child, and
adult. The OCM sends the Occupant Classification to the
ORC to determine if a front passenger airbag is allowed.
If a fault is present, the AIRBAG warning light is illumi-
nated.
How the Passenger Airbag Disabled (PAD)
Indicator Light Works
The Passenger Airbag Disabled (PAD) Indicator Light
indicates to the driver and passenger when the airbag is
turned OFF. In the presence of a properly seated occu-
pant, when the PAD indicator light is illuminated, the
airbag is OFF. Also, when the Occupant Classification
System detects either an empty seat or a weight less than
the predetermined threshold, the ORC will not illuminate
the PAD indicator light even though the airbag is turned
OFF.
How the Belt Tension Sensor (BTS) Works
The Belt Tension Sensor (BTS) is located at the outboard
passenger lap belt anchor. The BTS creates a signal based
on outboard lap belt tension. This signal is sent to the
OCM to ensure that the resultant bladder pressure in-
crease due to applied lap belt tension does not cause a
small occupant to be classified as a larger occupant
How the Bladder Mat and Pressure Sensor Works
The Bladder Mat and Pressure Sensor are located beneath
the seat cushion foam. The pressure sensor sends a signal
to the OCM. The passenger seat assembly contains criti-
cal components that affect the passenger airbag deploy-
ment. Correctly functioning passenger seat components
are critical for the Occupant Classification System (OCS)
to properly classify the passenger and calculate the
proper airbag deployment. Do not make any modifica-
tions to the passenger seat components, assembly, or to
the seat cover.

How the Driver/Passenger Inflatable Knee
Blockers Works
When the ORC and the impact sensors detect a collision
requiring the Driver/Passenger Inflatable Knee Blockers,
it signals the inflator unit. A quantity of nontoxic gas is
generated to inflate the Driver/Passenger Inflatable Knee
Blockers. The Driver/Passenger Inflatable Knee Blockers
inflates rearward towards the driver 's knees to help
protect the knees and position you for the best interaction
with the front airbag. The Driver/Passenger Inflatable
Knee Blockers fully inflates in about 50 milliseconds, this
is only about half of the time it takes you to blink your
eyes. It then quickly deflates while helping to protect the
driver 's knees.
The Knee Impact Blockers help protect the knees and
position the occupant.
Passenger Front Airbag On/Off Switch
The ON/OFF switch is located at the right end of the
instrument panel and is accessible by opening the pas-
senger door.
NOTE:When using certain types of child seats, the
passenger airbag light will remain off even though the
passenger front airbags are disabled.
It is always recommended to turn off the passenger front
air bags using the passenger front airbags on/off switch
located at the right end of the instrument panel when the
passenger is:
²an infant (less than 1 year old),
²a child, age 1 to 12,
²an adult with a medical condition which makes pas-
senger airbag inflation (deployment) a greater risk for
the passenger than the risk of hitting the dashboard
(instrument panel) or windshield in a crash.
The on/off switch is accessible by opening the passenger
door.

Infants and Child Restraints
There are different sizes and types of restraints for
children from newborn size to the child almost large
enough for an adult safety belt. Always check the child
seat Owner's Manual to ensure you have the right seat
for your child. Use the restraint that is correct for your
child:
²Safety experts recommend that children ride
rearward-facing in the vehicle until they are at least
one year old and weigh at least 9 kg (20 lbs.). Two
types of child restraints can be used rearward-facing:
infant carriers and ªconvertibleº child seats.
²The infant carrier is only used rearward-facing in the
vehicle. It is recommended for children who weigh up
to about 20 lbs. (9 kg). ªConvertibleº child seats can be
used either rearward-facing or forward-facing in the
vehicle. Convertible child seats often have a higher
weight limit in the rearward-facing direction than
infant carriers do, so they can be used rearward-facing
by children who weigh more than 20 lbs. (9 kg) but are
less than one year old. Both types of child restraints are
held in the vehicle by the lap/shoulder belt or theLATCH child restraint anchorage system. (See the
LATCH - Child Seat Anchorage System section.)
²Rearward-facing child seats mustNEVERbe used in
the front seat of a vehicle with the front passenger
airbag unless the airbag is turned off. An airbag
deployment could cause severe injury or death to
infants in this position.
WARNING!
²A rearward facing infant restraint must not be
used unless the passenger airbag has been shut
off. A rearward facing infant restraint may be
struck by a deploying passenger airbag which may
cause severe or fatal injury to the infant.
²Improper installation can lead to failure of a child
restraint. It could come loose in a collision. The
child could be badly injured or killed. Follow the
manufacturer's directions exactly when installing
a child restraint.
48 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE
Here are some tips on getting the most out of your child
restraint:
²Before buying any restraint system, make sure that it
has a label certifying that it meets all applicable Safety
Standards. We also recommend that you make sure
that you can install the child restraint in the vehicle
where you will use it before you buy it.
²The restraint must be appropriate for your child's
weight and height. Check the label on the restraint for
weight and height limits.
²Carefully follow the instructions that come with the
restraint. If you install the restraint improperly, it may
not work when you need it.
²Buckle the child into the seat according to the seat
manufacturer's directions.
²When your child restraint is not in use, secure it in the
vehicle with the seat belt or remove it from the vehicle.
Do not leave it loose in the vehicle. In a sudden stop or
collision, it could strike the occupants and cause
serious personal injury.
NOTE:For additional information refer to
www.seatcheck.org or call 1±866±SEATCHECK.
Older Children and Child Restraints
Children who weigh more than 20 lbs. (9 kg) and who are
older than one year can ride forward-facing in the
vehicle. Forward-facing child seats and convertible child
seats used in the forward-facing direction are for children
who weigh 20 to 40 lbs. (9 to 18 kg) and who are older
than one year. These child seats are also held in the
vehicle by the lap/shoulder belt or the LATCH child
restraint anchorage system. (See LATCH - Child Seat
Anchorage System section.)
The belt-positioning booster seat is for children weighing
more than 40 lbs. (18 kg), but who are still too small to fit
the vehicle's seat belts properly. If the child cannot sit
with knees bent over the vehicle's seat cushion while the
child's back is against the seat back, they should use a
belt-positioning booster seat. The child and belt-
positioning booster seat are held in the vehicle by the
lap/shoulder belt.

Children Too Large For Booster Seats
Children who are large enough to wear the shoulder belt
comfortably, and whose legs are long enough to bend
over the front of the seat when their back is against the
seat back, should use the lap/shoulder belt.
²Make sure that the child is upright in the seat.
²The lap portion should be low on the hips and as snug
as possible.
²Check belt fit periodically. A child's squirming or
slouching can move the belt out of position.
²If the shoulder belt contacts the face or neck, move the
child closer to the center of the vehicle. Never allow a
child to put the shoulder belt under an arm or behind
their back.
LATCH - Child Seat Anchorage System (Lower
Anchors and Tether for Children)
Your vehicle's passenger seat is equipped with the child
restraint anchorage system called LATCH. The LATCH
system provides for the installation of the child restraint
without using the vehicle's belts, instead securing the
child restraint using lower anchorages and upper tether
straps from the child restraint to the vehicle structure.
LATCH-compatible child restraints are now available.
Installing the LATCH-Compatible Child Restraint
System
We urge that you carefully follow the directions of the
manufacturer when installing your child restraint. These
are general instructions, and not all child restraint sys-
tems will be installed exactly as described here. Again,
carefully follow the installation instructions that were
provided with the child restraint system.
50 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE
The passenger seat lower anchorages are round bars,
located at the rear of the seat cushion where it meets the
seat back, and are just visible when you lean in to install
the child restraint. You will easily feel them if you run
your finger along the intersection of the seat back and
seat cushion surfaces.
The passenger seat tether anchorage is located on the
back of the seat cushion frame. It is visible by moving the
passenger seat forward in the vehicle.Many, but not all LATCH-Compatible child restraint
systems will be equipped with separate straps on each
side, with each having a hook or connector for attach-
ment to the lower anchorage and a means of adjusting
the tension in the strap. Forward-facing toddler restraints
and some rear-facing infant restraints will also be
equipped with a tether strap, a hook for attachment to the
tether strap anchorage and a means of adjusting the
tension of the strap.

You will first loosen the adjusters on the lower straps and
on the tether strap so that you can more easily attach the
hooks or connectors to the vehicle anchorages. Next, you
can attach the tether strap to the anchor by moving the
passenger seat forward. Route the child restraint tether
directly over the top of the seat, through the strap near
the top of the seat back, and attach the hook to the anchor
bar. Recline the seat back and move the passenger seat as
far rearward as possible. Next, attach the lower hooks to
the passenger seat lower anchor bars by pushing aside
the seat cover material. Finally, tighten all three straps as
you push the child restraint rearward and downward
into the seat, removing slack in the straps according to
the child restraint manufacturer's instructions.WARNING!
After installing a child safety seat or booster seat on
the passenger seat, do not adjust the back rest for-
ward. This could cause a higher load being perceived
by the OCS system which in turn could lead to the
passenger airbag being turned on. Failure to follow
this warning could result in serious or fatal injury. It
is always recommended to turn off the passenger
front air bags using the passenger front airbags
on/off switch located at the right end of the instru-
ment panel when the passenger is:
²an infant (less than 1 year old),
²a child, age 1 to 12,
²an adult with a medical condition which makes
passenger airbags inflation (deployment) a greater
risk for the passenger than the risk of hitting the
dashboard (instrument panel) or windshield in a
crash.
The on/off switch is accessible by opening the pas-
senger door.
52 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE
WARNING!
Improper installation of a child restraint to the
LATCH anchorages can lead to failure of an infant or
child restraint. The child could be badly injured or
killed. Follow the manufacturer's directions exactly
when installing an infant or child restraint.
Installing Child Restraints Using the Vehicle Seat
Belt
Child restraints can be securely fastened in the passenger
seat using the seat belts. For this purpose, the passenger
seat belt retractor provides two modes of operation -
normal emergency locking and automatic locking. For
child restraint installation, the retractor switches to auto-
matic locking when the belt is pulled out to the full extent
of its travel. As the belt retracts, the retractor locks to
prevent the belt from being pulled out again. Pulling the
belt snugly over the child restraint toward the retractor
secures the restraint in place. When the belt retracts fully
after child restraint removal, normal (emergency locking)retractor action is restored. Any seat belt system will
loosen with time, so check the belt occasionally and pull
it tight if necessary.
If your child restraint is equipped with a tether strap,
attach it to the vehicle by first moving the seat back fully
forward. Next, route the child restraint tether directly
over the top of the seat, through the strap near the top of
the seat back, and attach the hook to the anchor bar.
Recline the seat back and move the passenger seat as far
rearward as possible. Remove slack in the tether strap as
you push the child restraint downward and rearward,
following the child restraint manufacturer's instructions.
Child Restraint Tether Anchor - General
Information
Child restraints having tether straps and hooks for con-
nection to tether anchors have been available for some
time. In fact, many child restraint manufacturers will
provide add-on tether strap kits for certain of their older
products. There is a tether strap anchor behind the
passenger seat.
