How the Airbag System Works
•
TheOccupant Restraint Controller (ORC) determines
if a frontal, side, or rollover collision is severe enough
to require the airbags to inflate. The front airbag
inflators are designed to provide different rates of
airbag inflation from direction provided by the ORC.
The ORC may also modify the rate of inflation based
on the occupant size. The ORC receives this data from
the Occupant Classification Module (OCM). The ORC
will detect rollovers, but not rear impacts.
58 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

The “PAD Indicator Light” should not be illuminated
when an adult passenger is properly seated in the
front passenger seat. In this case, the airbag is ready to
be inflated if a collision requiring an airbag occurs. For
all other occupants, the “PAD Indicator Light” will be
illuminated indicating that the front passenger airbag
is turned off and it will not inflate. If the “PAD
Indicator Light” is not illuminated,DO NOTassume
the airbag is turned off and move the child restraint to
the rear seat. A deploying passenger airbag can cause
death or serious injury to a child in a rear facing infant
seat.
NOTE: Even though this vehicle is equipped with an
Occupant Classification System, children 12 years and
younger should always ride buckled up in a rear seat in
an appropriate child restraint.

* Since the system senses weight, some small objects will turn the PAD Indicator Light on.
The OCS classifies an occupant using weight sensors
mounted in the base of the front passenger seat. Any
weight on the seat will be sensed by the system. Objects
hanging on the seat or other passengers pushing down
on the seat will also be sensed. The weight of an adult

will cause the system to turn the airbag on. In this case,
the OCS has classified the occupant of the seat as an
adult. An adult occupant needs to sit in a normal position
(with their feet on or near the floor) in order to be
properly classified. Reclining the seat back too far may
change how an occupant is classified by the OCS.
Drivers and adult passengers should verify that the
“PAD Indicator Light” is not illuminated when an adult
is riding in the front passenger seat. If an adult occu-
pant’s weight is transferred to another part of the vehicle
(like the door or instrument panel), the weight sensors in
the seat may not properly classify the occupant. Objects
lodged under the seat or between the seat and the center
console can prevent the occupant’s weight from being
measured properly and may result in the occupant being
improperly classified. Ensure that the front passenger
seatback does not touch anything placed on the back seatbecause this can also affect occupant classification. Also,
if you fold down the rear seat check to be sure it doesn’t
touch the front passenger seat.
If the front passenger seat is damaged in any way, it
should only be serviced by an authorized dealer. If the
seat is removed (or even if the seat attachment bolts are
loosened or tightened in any way), take the vehicle to an
authorized dealer.
If there is a fault present in the OCS, the “Airbag Warning
Light” (a red light located in the center of the instrument
cluster directly in front of the driver) will be turned on.
This indicates that you should take the vehicle to an
authorized dealer. The “Airbag Warning Light” is turned
on whenever there is a fault that can affect the operation
of the airbag system. If there is a fault present in the OCS,
both the “PAD Indicator Light” and the “Airbag Warning
Light” are illuminated to show that the passenger airbag
is turned off until the fault is cleared. If an object is
62 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

lodged under the seat and interferes with operation of
the weight sensors, a fault will occur which turns on both
the “PAD Indicator Light” and the “Airbag Warning
Light.” Once the lodged object is removed, the fault will
be automatically cleared after a short period of time.
•TheDriver and Passenger Airbag/Inflator Units are
located in the center of the steering wheel and the
passenger side of the instrument panel. When the ORC
detects a collision requiring the airbags, it signals the
inflator units. A large quantity of non-toxic gas is
generated to inflate the front airbags. Different airbag
inflation rates are possible, based on collision severity
and occupant size. The steering wheel hub trim cover
and the upper passenger side of the instrument panel
separate and fold out of the way, as the bags inflate to
their full size. The bags fully inflate in about 50 to 70
milliseconds. This is about half of the time that it takes
to blink your eyes. The bags then quickly deflate while
helping to restrain the driver and front passenger. The driver’s front airbag gas is vented through the vent
holes in the sides of the airbag. The passenger’s front
airbag gas is vented through the vent holes in the sides
of the airbag. In this way, the airbags do not interfere
with your control of the vehicle.•The
Occupant Classification Module (OCM) is lo-
cated beneath the front passenger seat. The OCM
classifies the occupant into categories based on the
measurements made by the seat weight sensors. The
OCM communicates with the Occupant Restraint Con-
troller (ORC). The ORC uses the occupant category to
determine whether the front passenger airbag should
be turned off. It also determines the rate of airbag
inflation during a collision.
•Your vehicle has four Weight Sensorslocated between
the seat and the floor pan. The weight sensors measure
applied weight and transfers that information to the
OCM.

WARNING! (Continued)
•Do not place or hang any items such as add-on
video players on the front passenger seatback. The
additional weight may cause the Occupant Classi-
fication System to be unable to classify the front
seat passenger correctly. This could allow the
passenger frontal airbag to inflate when it is not
desired.
•It is dangerous to try to repair any part of the
airbag system yourself. Be sure to tell anyone who
works on your vehicle that it has an airbag system.
Airbag Warning Light
You will want to have the airbag system ready to inflate
for your protection in an impact. The airbag system is
designed to be maintenance free. If any of the following
occurs, have an authorized dealer service the system
promptly:
•The Airbag Warning Light does not come on or flickers
during the six to eight seconds when the ignition
switch is first turned ON.
•The light remains on or flickers after the six to eight
second interval.
•The light flickers or comes on and remains on while
driving.

Infants and Child Restraints
•
Safety experts recommend that children ride
rearward-facing in the vehicle until they are at least
one year oldandweigh at least 20 lbs (9 kg). Two types
of child restraints can be used rearward-facing: infant
carriers and “convertible” child seats.
•The infant carrier is only used rearward-facing in the
vehicle. It is recommended for children who weigh up
to about 20 lbs (9 kg). “Convertible” 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 the
LATCH child restraint anchorage system. Refer to “LATCH — Child Seat Anchorage System (Lower
Anchors and Tether for CHildren)” in this section.
•Rearward-facing child seats must
NEVERbe 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.
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. Refer to “LATCH — Child
Seat Anchorage System (Lower Anchors and Tether for
CHildren)” in this section.

WARNING! (Continued)
•A rearward- facing infant restraint should only be
used in a rear seat. A rearward-facing infant re-
straint in the front seat may be struck by a deploy-
ing passenger airbag, which may cause severe or
fatal injury to the infant.
Here are some tips on getting the most out of your child
restraint:
•Before buying any restraint system, make sure that it
has a label certifying that it meets all applicable Safety
Standards. The manufacturer also recommends that
you try a child restraint in the vehicle seats where you
will use it before you buy it.
•The restraint must be appropriate for your child’s
weight and height. Check the label on the restraint for
weight and height limits.
•Carefully follow the instructions that come with the
restraint. If you install the restraint improperly, it may
not work when you need it.
•Buckle the child into the restraint exactly as the
manufacturer’s instructions tell you.
•When 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 or seat backs
and cause serious personal injury.
LATCH — Child Seat Anchorage System (Lower
Anchors and Tether for CHildren)
Your vehicle’s rear 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 seat belts, instead securing

WARNING!
•Cargo tie-downs are not safe anchors for a child
seat tether strap. In a sudden stop or collision, a
tie-down could pull loose and allow the child seat
to come loose. A child could be badly injured. Use
only the anchors provided for child seat tethers.
•To help protect against personal injury, passengers
should not be seated in the rear cargo area. The
rear cargo space is intended for load carrying
purposes only, not for passengers, who should sit
in seats and use seat belts.
WARNING!
The weight and position of cargo and passengers can
change the vehicle center of gravity and vehicle
handling. To avoid loss of control resulting in per-
sonal injury, follow these guidelines for loading your
vehicle:
•Do not carry loads that exceed the load limits
described on the label attached to the left door or
left door center pillar.
•Always place cargo evenly on the cargo floor. Put
heavier objects as low and as far forward as
possible.
•Place as much cargo as possible in front of the rear
axle. Too much weight or improperly placed
weight over or behind the rear axle can cause the
vehicle to sway.(Continued)
