The Head/Thorax airbag system (if equipped) consists
of the following:
²AIRBAG Readiness Light (shared with the front airbag
system)
²Front SeatÐ side mounted Head/Thorax Airbags Ð if
equipped
²Airbag Control Module (shared with the front airbag
system)
²Side impact sensors
How The Airbag System Works
²
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 mayalso modify the rate of inflation based on the occupant
size provided by the Occupant Classification Module.
The ORC will not detect roll over.
The ORC also 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, and knee blocker panels. 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.
During a moderate-to-severe rear impact the ORC may
deploy the seat belt pretensioners alone.
Also, the ORC turns on the AIRBAG warning
light and PAD indicator light in the instrument
panel for six to eight 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
60 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE
Page 61 of 488

9Passenger Airbag Disable (PAD) Indicator Light9in this
section). If the ORC detects a malfunction in any part of
the system, it turns on the AIRBAG warning light either
momentarily or continuously. A single chime will sound
if the light comes on again after initial start up.
WARNING!
Ignoring the AIRBAG light in your instrument 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.
²When the front airbag control module detects a colli-
sion requiring the front airbags, it signals the inflator
units. A large quantity of nontoxic gas is generated to
inflate the front airbags. The front airbag covers sepa-
rate and fold out of the way as the front airbags inflateto their full size. The front airbags fully inflate in about
50 milliseconds. This is only about half of the time it
takes you to blink your eyes. The front 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 holes in the sides of the
airbag. In this way the front airbags do not interfere
with your control of the vehicle.
²ThePassenger 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 words9PASS AIRBAG OFF9
to show that the front passenger airbag will not inflate
during a collision requiring airbags. When the right
front passenger seat is empty or when very light
objects are placed on the seat, the passenger airbag
will not inflate even though the PAD indicator lamp is
not illuminated.

²The PAD indictor light should not be illu-
minated when an adult passenger is prop-
erly 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 will not inflate.NOTE:Even though this vehicle is equipped with an
occupant classification system, children 12 years and
under should always ride buckled up in a rear seat in an
appropriate child restraint (see section on child re-
straints).
WARNING!
Never place a rear facing infant seat in front of an
airbag. A deploying passenger airbag can cause death
or serious injury to a child in a rear facing infant seat.

* Since the system senses weight, some small objects
will turn the PAD Indicator Light on.
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 occupant's weight
is transferred to another part of the vehicle (like the door
or instrument panel), the weight sensors in the seat maynot 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 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 autho-
rized 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 PAD
Indicator Light the Airbag Warning Light remains illu-
minated 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.
²TheDriver 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 ratesmay 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.
²TheOccupant 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 ORC. The ORC uses the
occupant category to determine whether the front

²Do not replace the seat cover with an aftermarket seat
cover.
²Do not add a secondary seat cover other than those
approved by DaimlerChrysler/Mopart.
²At no time should any supplemental restraint system
(SRS) component or SRS related component or fas-
tener be modified or replaced with any part except
those which are approved by DaimlerChrysler/
Mopart.
WARNING!
Unapproved modifications or service procedures to
the front passenger seat assembly, its related compo-
nents, or seat cover may inadvertently change the
airbag deployment in case of a frontal crash. This
could result in death or serious injury to the front
seat passenger if the vehicle is involved in an
accident.
If A Deployment Occurs
The airbag systems are designed to deploy when the
airbag control modules detect a moderate-to-severe col-
lision, to help restrain the driver and front passenger, and
then immediately deflate.

WARNING!
Deployed airbags and seat belt pretensioners cannot
protect you in another collision. Have the airbags,
seat belt pretensioners, front passenger seat belt
retractor assembly and Occupant Classification Sys-
tem, replaced by an authorized dealer as soon as
possible.
Maintaining Your Airbag System
WARNING!
Modifications to any part of the airbag system could
cause it to fail when you need it. You could be
injured if the airbag system is not there to protect
you. Do not modify the components or wiring, in-
cluding adding any kind of badges or stickers to the
steering wheel hub trim cover or the upper right side
of the instrument panel. Do not modify the front
bumper, vehicle body structure, or add aftermarket
side steps or running boards.

WARNING!
Do not attempt to modify any part of your advanced
airbag system. The airbag may inflate accidentally or
may not function properly if modifications are made.
Take your vehicle to an authorized dealer for any
advanced airbag system service. If your seat includ-
ing your trim cover and cushion needs to be serviced
in any way (including removal or loosening/
tightening of seat attachment bolts), take the vehicle
to your authorized dealer. Only manufacturer ap-
proved seat accessories may be used. If it is necessary
to modify an advanced airbag system for persons
with disabilities, contact your authorized dealer.
WARNING!
²Do not place or hang any items such as add-on
video players on the front seat backs. The addi-
tional weight may cause the Occupant Classifica-
tion System to be unable to correctly classify the
right front occupant. This could allow the passen-
ger frontal airbag to inflate when it is not desired.
²You need proper knee impact protection in a
collision. Do not mount or locate any aftermarket
equipment on or behind the knee blocker panel.
²It 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.
