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 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.
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 and
impact sensors detects a collision requiring the air-
bags, it signals the inflator units. A large quantity ofnontoxic gas is generated to inflate the front airbags.
Different airbag inflation rates may be possible based
on collision severity. 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.²TheSide Airbag Inflatable Curtainsare designed to
activate only in certain side collisions. When the ORC
and the side impact sensors (with side impact option)
detects a collision requiring the window bags to

inflate, it signals the inflators on the crash side of the
vehicle. A quantity of nontoxic gas is generated to
inflate the window bag. The inflating window bag
pushes the outside edge of the headliner out of the
way and covers the window. The airbag inflates in
about 30 milliseconds (about one quarter of the time it
takes to blink your eyes) with enough force to injure
you if you are not belted and seated properly, or if
items are positioned in the area where the window bag
inflates. This especially applies to children. The win-
dow bag is only about 3
1¤2inches (9 cm) thick when it
is inflated.
²When the ORC and the impact sensors detect a
collision requiring theDriver Inflatable Knee Blocker
Ð If Equipped,signals the inflator unit. A quantity of
nontoxic gas is generated to inflate the Driver Inflat-
able Knee Blocker. The Driver Inflatable Knee Blocker
inflates rearward towards the driver's knees to helpprotect 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.
²TheKnee Impact Bolstershelp protect the knees, and
position everyone for the best interaction with the
front airbag.
²If your vehicle contains a Passenger Airbag Disable
indicator light, it will be equipped with theOccupant
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
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 57

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.)
58 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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 frontpassenger 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.
²TheOccupant Classification Module (OCM) Ð If
Equippedis located beneath the front passenger seat.
The OCM classifies the occupant into one of three size
categories based on the input from the Bladder Assem-
bly and Belt Tension Sensor. The size categories in-
clude empty, child, and adult. The OCM sends the
Occupant Classification to the ORC to identify if a
Passenger Airbag Light Ð If OCS Equipped

front passenger airbag is allowed. If a fault is present,
the AIRBAG warning light is illuminated.
²ThePassenger Airbag Disabled (PAD) Indicator
Light Ð If Equippedindicates 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 Occupant Classification System (OCS) de-
tects 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.
²TheBelt Tension Sensor (BTS) Ð If Equippedis
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 thatthe resultant bladder pressure increase due to applied
lap belt tension does not cause a small occupant to be
classified as a larger occupant.
²TheBladder Assembly Ð If Equippedis 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.
60 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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 acci-
dent. A modified vehicle may not comply with re-
quired Federal Motor Vehicle Safety Standards
(FMVSS).
The following requirements must be strictly adhered to:
²Do not modify the front passenger seat assembly or
components in any way.
²Do not modify the front seat center console or center
position seat in any way.
²Do not use prior or future model year seat covers not
designated for the specific model being repaired. Al-
ways use the correct seat cover specified for the
vehicle.
²Do not replace the seat cover with an aftermarket seat
cover.
²Do not add a secondary seat cover other than those
approved by DaimlerChrysler/Mopar.
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/
Mopar.

If A Deployment Occurs
The airbag system is designed to deploy the airbags
when the ORC and impact sensors detect a moderate-to-
severe collision, to help restrain the vehicle passengers,
and then immediately deflate.
NOTE:A collision that is not severe enough to need
airbag protection will not activate the system. This does
not mean something is wrong with the airbag system.
If you do have a collision which deploys the airbags, any
or all of the following may occur:
²The nylon airbag material may sometimes cause abra-
sions and/or skin reddening to the driver and front
passenger as the airbags deploy and unfold. The
abrasions are similar to friction rope burns or those
you might get sliding along a carpet or gymnasium
floor. They are not caused by contact with chemicals.
They are not permanent and normally heal quickly.However, if you haven't healed significantly within a
few days, or if you have any blistering, see your doctor
immediately.
²As the airbags deflate you may see some smoke-like
particles. The particles are a normal by-product of the
process that generates the nontoxic gas used for airbag
inflation. These airborne particles may irritate the skin,
eyes, nose, or throat. If you have skin or eye irritation,
rinse the area with cool water. For nose or throat
irritation, move to fresh air. If the irritation continues,
see your doctor. If these particles settle on your
clothing, follow the garment manufacturer's instruc-
tions for cleaning.
²It is not advisable to drive your vehicle after the
airbags have deployed. If you are involved in another
collision, the airbags will not be in place to protect you.
62 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!
Deployed airbags, front seat belt pretensioners and
driver inflatable knee blocker cannot protect you in
another collision. Have the airbags, front seat belt
pretensioners and driver inflatable knee blocker (if
equipped) replaced by an authorized dealer as soon
as possible.
Enhanced Accident Response
If the airbags and seat belt pretensioners deploy after an
impact and the electrical system remains functional,
vehicles equipped with power door locks will unlock
automatically. In addition, approximately 10 seconds
after the vehicle has stopped moving, the interior lights
will illuminate until the ignition switch is turned off.In the event of an impact that causes airbag deployment,
with the vehicle stopped, and the vehicle communication
network intact, and the power intact, the Enhanced
Accident Response System performs the following func-
tions:
²Cuts off fuel to the engine
²Flashes hazard lights
²Turns on the interior lights approximately 10 seconds
after the vehicle has stopped moving, and will remain
on as long as the battery has power or until the
ignition key is removed
²Unlocks the doors automatically

Maintaining Your Airbag System
WARNING!
²Modifications to any part of the airbag system
could cause it to fail when you need it. You could
be injured because the airbags are not there to
protect you. Do not modify the components or
wiring, including 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 frame.
²Do not attempt to modify any part of your ad-
vanced airbag system. The airbag may inflate
accidentally or may not function properly if modi-
fications are made. Take your vehicle to an autho-
rized dealer for any advanced airbag system ser-
vice. If it is necessary to modify an advanced
airbag system for persons with disabilities, contact
your authorized dealer.
WARNING!
²You need proper knee impact protection in a
collision. Do not mount or locate any aftermarket
equipment on or behind the knee bolsters.
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 airbags.
NOTE:Perchlorate Material Ð special handling may
apply. See www.dtsc.ca.gov/hazardouswaste/
perchlorate.
Airbag Light
You will want to have the airbags ready to
inflate for your protection in a collision. While
the airbag system is designed to be mainte-
nance free, if any of the following occurs, have
an authorized dealer service the system immediately.
64 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

²The AIRBAG light does not come on or flickers during
the 6 to 8 seconds when the ignition switch is first
turned on.
²The light remains on or flickers after the 6 to 8 second
interval.
²The light flickers or comes on and remains on while
driving.
Event Data Recorder (EDR)
In the event of an accident, your vehicle is designed to
record up to 5 seconds of specific vehicle data parameters
(see the following list) in an event data recorder prior to
the moment of airbag deployment, or near deployment,
and up to a quarter second of high-speed deceleration
data during and/or after airbag deployment. EDR data
are ONLY recorded if an airbag deploys, or nearly
deploys, and are otherwise unavailable.NOTE:
1. A near-deployment event occurs when the airbag
sensor detects severe vehicle deceleration usually indica-
tive of a crash, but not severe enough to warrant airbag
deployment.
2. Under certain circumstances, EDR data may not be
recorded (e.g., loss of battery power).
In conjunction with other data gathered during a com-
plete accident investigation, the electronic data may be
used by DaimlerChrysler Corporation and others to learn
more about the possible causes of crashes and associated
injuries in order to assess and improve vehicle perfor-
mance. In addition to crash investigations initiated by
DaimlerChrysler Corporation, such investigations may
be requested by customers, insurance carriers, govern-
ment officials, and professional crash researchers, such as
those associated with universities, and with hospital and
insurance organizations.
