How The Airbag System Works
•
TheOccupant Restraint Controller (ORC)determines
if a frontal collision is severe enough to require the
airbags to inflate. The front airbag inflators are de-
signed 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 provided by the Occupant Classification Module.
The ORC will not detect roll over.
60 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

•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 push-
ing 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.
•ThePassenger Airbag Disable (PAD) Indicator Light
(an amber light located in the center of the instrument
panel) tells the driver and front passenger when the
front passenger airbag is turned off. The PAD Indica-
tor lamp illuminates the wordsPASS AIR BAG OFF
to show that the front passenger airbag will not inflate
during a collision requiring airbags. When the rightfront passenger seat is empty or when very light
objects are placed on the seat, the passenger air bag
will not inflate even though the Passenger Airbag
Disable (PAD) indicator lamp is not illuminated.
The PAD indictor light should not be illuminated
when an adult passenger is properly seated in the

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 improp-
erly classified. Ensure that the front passenger seat back
does not touch anything placed on the second row of
seats because this can also affect occupant classification.
Also, if you fold down the seats in the second row check
to be sure they don’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 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 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 Unitsare
located in the center of the steering wheel and the right
side of the instrument panel. When the ORC detects a
collision requiring the airbags, it signals the inflator
units. A large quantity of nontoxic gas is generated to
inflate the front airbags. Different airbag inflation rates

may be possible based on collision severity and occu-
pant size. The steering wheel hub trim cover and the
upper right 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 - 70 milliseconds.
This is about half of the time 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 vent holes in the sides of
the airbag. The passenger’s front airbag gas is vented
through vent holes in the sides of the airbag. In this
way the airbags do not interfere with your control of
the vehicle.
•TheOccupant 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 todetermine whether the front passenger airbag should
be turned off. It also determines the rate of airbag
inflation during a collision.
•Your vehicle has fourWeight Sensorslocated between
the seat and the floor pan. The weight sensors measure
applied weight and transfers that information to the
OCM.
•TheSide Impact (SRS) Seat Mounted Side Airbags
(If equipped)are designed to activate only in certain
side collisions.
The ORC module determines if a side collision is
severe enough to require the side airbags to inflate.
The side airbag control module will not detect roll
over, front or rear collisions.

The ORC Module monitors the readiness of the electronic
parts of the system whenever the ignition switch is in the
START or ON positions. These include all of the items
previously mentioned.
In moderate to severe side collisions, the side airbag
inflator on the crash side of the vehicle is triggered,
releasing a quantity of nontoxic gas. The inflating side
airbag exits through the seat seam into the space between
the occupant and the door. The side airbag moves at a
very high speed and with such a high force, that it could
injure you if you are not seated properly, or if items are
positioned in the area where the side airbag inflates. This
especially applies to children.
•When the ORC and the impact sensors detect a
collision requiring theDriver Inflatable Knee
Blocker, it signals the inflator unit. A quantity of
nontoxic gas is generated to inflate the Driver Inflat-
able Knee Blocker. The Driver Inflatable Knee Blockerinflates rearward towards the driver’s knees to help
protect the knees and position you for the best inter-
action with the front airbag. The Driver Inflatable
Knee Blocker 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.
•TheKnee Impact Bolstershelp protect the knees, and
position everyone for the best interaction with the
front airbag.
The front passenger seat assembly contains critical com-
ponents that affect the front passenger airbag deploy-
ment. Correctly functioning front passenger seat compo-
nents are critical for the Occupant Classification System
(OCS) to properly classify the front passenger and calcu-
late the proper airbag deployment. Do not make any
modifications to the front passenger seat components,
assembly, or to the seat cover.
