AIRBAG DEPLOYMENT SENSORS AND
CONTROLS
Occupant Restraint Controller (ORC)
The Occupant Restraint Controller System (ORC) is
part of a Federally regulated safety system required for
this vehicle.
The ORC determines if a frontal collision is severe
enough to require the airbags to inflate. Based on the
sensor signals, a central electronic Occupant Restraint
Controller (ORC) deploys the front airbags, side inflat-
able airbag curtains (if equipped), seat-mounted side
(Thorax) airbags (if equipped), and front seat belt preten-
sioners as required for each type of impact.
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 bolsters. 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.
The ORC contains a backup power supply system that
will deploy the airbags even if the battery loses power or
it becomes disconnected prior to deployment.
Also, the ORC turns on the Airbag Warning
Light in 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. 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.
It also includes diagnostics that will illuminate the instru-
ment cluster Airbag Warning Light if a malfunction is
noted. The diagnostics also record the nature of the
malfunction. THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 59

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.
Impact Sensors
Two sensors, located on the front body structure, trigger
airbag deployment in direct frontal impacts and aid the
Occupant Restraint Controller (ORC) in determining
appropriate response to frontal impact events. Additional
sensors in the ORC determine the level of airbag deploy-
ment and provide deployment verification. Side Inflatable Curtain and Front Seat Mounted
Airbags Ð If equipped
The Occupant Restraint Controller System (ORC) de-
ploys the side inflatable curtain and seat mounted thorax
side airbags during collision with other vehicles and
during collisions where the impact is confined to a
particular area of the vehicle Ð such as collisions with
poles, trees or similar objects.
It will deploy the side inflatable curtains and front seat
thorax mounted airbags only on the impact side of the
vehicle.
The front driver and passenger seat contain inflatable
side airbags to protect the occupant from impact injuries.
Correctly functioning front passenger seat components
are critical for the Occupant Restraint Controller System60 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

(ORC) 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.
The following requirements must be strictly adhered to:
² Do not make any modifications to the front passenger
seat components, assembly, or to the seat cover in any
way.
² Do 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.
² Do not replace the seat cover with an aftermarket seat
cover.
² Do not add a secondary seat cover other than those
approved by DaimlerChrysler/Mopar. ² At 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.
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). THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 61

Enhanced Accident Response System
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:
² Cuts off fuel to the engine
² Flashes hazard lights
² Turns on the interior lights which remain on as long as
the battery has power or until the ignition key is
removed
² Unlocks the doors automatically
If A Deployment Occurs
The airbag systems are designed to deploy when the
Occupant Restraint Controller (ORC) detect a moderate-
to-severe collision, to help restrain the driver and front
passenger, and then immediately deflate. NOTE: A frontal 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:
² The 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.
² As the airbags deflate, you may see some smoke-like
particles. The particles are a normal by-product of the62 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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.
² It 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. WARNING!Deployed airbags and seat belt pretensioners cannot
protect you in another collision. Have the airbags,
seat belt pretensioners, and the front passenger seat
belt retractor assembly, replaced by an authorized
dealer as soon as possible. Also, have the Occupant
Restraint Controller System serviced as well. THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 63

Maintaining Your Airbag System
WARNING!² 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, 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 add aftermarket side steps or running boards.
² 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. NOTE:
Perchlorate Material Ð special handling may ap-
ply. See www.dtsc.ca.gov/hazardouswaste/perchlorate
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.64 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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.
² The AIRBAG light does not come on during the 6 to 8
seconds when the ignition switch is first turned on.
² The light remains on after the 6 to 8 second interval.
² The light comes on and remains on while driving.
NOTE: If the speedometer, tachometer, or any engine
related gauges are not working, the Occupant Restraint
Controller (ORC) may also be disabled. The airbags may
not be ready to inflate for your protection. Promptly
check fuse block for blown fuses. Refer to the label
located on the inside of the fuse block cover for the
proper airbag fuses. See your dealer if the fuse is good. 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 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 65

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.
In the event that an investigation is undertaken by
DaimlerChrysler Corporation (regardless of initiative),
the company or its designated representative will first
obtain permission of the appropriate custodial entity for
the vehicle (usually the vehicle owner or lessee) before
accessing the electronic data stored, unless ordered to
download data by a court with legal jurisdiction (i.e.,
pursuant to a warrant). A copy of the data will be
provided to the custodial entity upon request. General
data that does not identify particular vehicles or crashes may be released for incorporation in aggregate crash
databases, such as those maintained by the US govern-
ment and various states. Data of a potentially sensitive
nature, such as would identify a particular driver, ve-
hicle, or crash, will be treated confidentially. Confidential
data will not be disclosed by DaimlerChrysler
Corporation to any third party except when:
1. Used for research purposes, such as to match data
with a particular crash record in an aggregate database,
provided confidentiality of personal data is thereafter
preserved.
2. Used in defense of litigation involving a
DaimlerChrysler Corporation product.
3. Requested by police under a legal warrant.
4. Otherwise required by law.66 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

CHILD RESTRAINT
Everyone in your vehicle needs to be buckled up at all
times Ð babies and children, too. Every state in the
United States and all Canadian provinces require that
small children ride in proper restraint systems. This is the
law, and you can be prosecuted for ignoring it.
Children 12 years and under should ride properly buck-
led up in a rear seat, if available. According to crash
statistics, children are safer when properly restrained in
the rear seats, rather than in the front. THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 67

WARNING!In a collision, an unrestrained child, even a tiny baby,
can become a missile inside the vehicle. The force
required to hold even an infant on your lap could
become so great that you could not hold the child, no
matter how strong you are. The child and others
could be badly injured. Any child riding in your
vehicle should be in a proper restraint for the child's
size.
There are different sizes and types of restraints for
children from newborn size to the child almost large
enough for an adult safety belt. Always check the child
seat owner's manual to ensure you have the correct seat
for your child. Use the restraint that is correct for your
child. Infants And Small Children
² Safety experts recommend that children ride
rearward-facing in the vehicle until they are at least
one year old and weigh at least 20 lbs (9 kg). Two types
of child restraints can be used rearward-facing: infant
carriers and 9 convertible 9 child seats. Both types of
child restraints are held in the vehicle by the lap/
shoulder belt or the LATCH child restraint anchorage
system.
² 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). 9 Convertible 9 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.68 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE
