2006 CHRYSLER PACIFICA airbag disable

If your vehicle is equipped with the Occupant Classifi-
cation System (OCS) there will be a Passenger Airbag
Disabled (PAD) Indicator Light located on the center of
the instrument panel. NOTE:
The front airbags have a multi stage inflator
design. This allows the airbag to have different rates of
inflation that are based on collision severity.
Please pay close attention to the information in this
section. It tells you how to use your restraint system
properly to keep you and your passengers as safe as
possible.
WARNING!
In a collision, you and your passengers can suffer
much greater injuries if you are not properly buck-
led up. You can strike the interior of your vehicle or
other passengers, or you can be thrown out of the
vehicle. Always be sure you and others in your
vehicle are buckled up properly.

How The Airbag System Works
•
The Occupant Restraint Controller (ORC) determines
if a frontal collision is severe enough to require the
airbags to inflate. Based on the level of collision
severity, the front control module determines the proper rate of inflation. The front airbag inflators are
designed to provide different rates of airbag inflation.
•The ORC may modify the rate of inflation based on the
occupant size provided by the Occupant Classification
Module.
•The ORC will not detect side, roll over, or rear impacts.
•The ORC monitors the readiness of the electronic parts
of the system whenever the ignition switch is in the
START or RUN positions. These include all of the
items listed above except the steering wheel and
column, instrument panel and passenger knee bol-
sters. If the key is in the OFF position, in the ACC
position, or not in the ignition, the airbags are not on
and will not inflate.
•Also, the ORC turns on the AIRBAG warn-
ing light and PAD indicator light in the
center of the instrument panel for 6 to 8
seconds for a self-check when the ignition is

first turned on. After the self-check, the AIRBAG
warning light will turn off. The PAD indicator light
will function normally (Refer to “Passenger Airbag
Disable (PAD) Indicator Light” in this section). If the
ORC detects a malfunction in any part of the system, it
turns on the AIRBAG warning light either momen-
tarily or continuously. A single chime will sound if the
light comes on again after initial start up.
WARNING!
Ignoring the AIRBAG warning light in your instru-
ment panel could mean you won’t have the airbags
to protect you in a collision. If the light does not
come on, stays on after you start the vehicle, or if it
comes on as you drive, have the airbag system
checked right away.
•The Driver and Passenger Airbag/Inflator Units are
located in the center of the steering wheel and the right
side of the instrument panel. When the ORC and
impact sensors detects a collision requiring the air-
bags, 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 occupant 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 airbags inflate to their full size. The airbags fully
inflate in about 50–70 milliseconds. This is about half
of the time it takes to blink your eyes. The airbags then
quickly deflate while helping to restrain the driver and
front passenger.
The driver’s and passenger’s front airbag gas is vented
through the airbag material towards the instrument
panel. In this way the airbags do not interfere with
your control of the vehicle.

•If your vehicle contains a Passenger Airbag Disable
indicator light, it will be equipped with the Occupant
Classification System (OCS). The OCS system will
classify an occupant into a size category based on
sensor readings from within the seat cushion. Occu-
pants should try to remain in a normally seated
position. If the occupant’s weight is transferred to
another object in the vehicle (i.e. feet on the dash-
board), the OCS may not be able to properly approxi-
mate occupant size. Furthermore, the occupant size
may appear to increase or decrease due to objects
hanging on the seat, other passengers pushing on the
seat, or objects lodged underneath the seat.
If there is a rapid change in temperature or humidity,
the OCS may not be able to properly approximate
occupant size. If your seat including your trim cover and cushion needs to be serviced in any way (includ-
ing removal or loosening/tightening of seat attach-
ment bolts), take the vehicle to your authorized dealer.
Only manufacturer approved seat accessories may be
used.
If there is a fault present in the system, the AIRBAG
warning light will illuminate indicating that you should
take the vehicle to an authorized dealer. In the presence
of an occupant in the passenger seat, if both the PAD
indicator light and AIRBAG warning light are illumi-
nated the airbag will be disabled.
The ORC will not allow front airbag deployment in the
event of a collision for occupants classified into the
empty or child size categories. The PAD indicator light
will illuminate indicating that the Passenger Airbag is
OFF when the OCS has determined that the occupant size
category is a child. Also, when the seat is empty or an
object that weighs less than a predetermined threshold is

placed on the seat, the light will remain OFF. (The PAD
indicator light is an amber light located on the center of
the instrument panel above the climate controls.)
For almost all sizes of properly seated adults, the airbag
will be enabled in the event of a collision. For small
teenagers and some small adults, depending on size, the airbag may or may not be enabled in the event of a
collision. Both drivers and passengers should always use
the PAD indicator light as an indication if the front
passenger is properly positioned or not. If the PAD
indicator light comes on when an adult is in the passen-
ger seat, have the passenger re-position themselves in the
seat until the light goes out.
Remember, if the PAD indicator light is illuminated the
passenger front airbag will not inflate. For properly
installed child restraint systems and children properly
seated on the front passenger seat, the airbag will be
disabled. If at all possible, place children 12 years and
younger in a back seat.
•The
Occupant Classification Module (OCM) is lo-
cated beneath the front passenger seat. The OCM
classifies the occupant into one of three size categories
based on the input from the Bladder Assembly and
Belt Tension Sensor. The size categories include empty,
Passenger Airbag Disabled Light
54 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

child, and adult. The OCM sends the Occupant Clas-
sification to the ORC to identify if a front passenger
airbag is allowed. If a fault is present, the AIRBAG
warning light is illuminated.
•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 occupant. When the PAD indicator light is
illuminated, the airbag is OFF. Also, when the Occu-
pant Classification System (OCS) detects either an
empty seat of a weight less than the predetermined
occupant threshold, the ORC will not illuminate the
PAD indicator light even though the airbag is turned
off. When the OCS detects an adult the PAD indicator
light will be off, and the airbag will be enabled.
•The Belt Tension Sensor (BTS) is located at the
outboard passenger lap belt anchor. The BTS generates
a signal based on outboard lap belt tension. This signal is sent to the OCM to ensure that the resultant bladder
pressure increase due to applied lap belt tension does
not cause a small occupant to be classified as a larger
occupant.
•The
Bladder Assembly is located beneath the seat
cushion foam. The pressure sensor sends a signal to
the OCM.
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.
