2008 CHRYSLER 300 SRT Owners Manual

Airbag System Components
The airbag system consists of the following:
•Occupant Restraint Controller (ORC)
•Side Remote Acceleration Sensors (if equipped)
•Airbag Warning Light
•Driver Airbag
•Front Passenger Airbag
•Supplemental Side Curtain Airbags above side win-
dows (if equipped)
•Supplemental Front Seat Mounted Side Airbags (if
equipped)
•Steering Wheel and Column
•Instrument Panel
•Interconnecting Wiring
•Seat Belt Reminder Light
•Knee Impact Bolsters
•Front Acceleration Sensors
•Driver and Front Passenger Seat Belt Pretensioners
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 will not
detect rollover.
•For vehicles so equipped, the ORC also determines if a
side impact is severe enough to deploy the supple-
mental side curtain airbag and/or supplemental front
seat mounted side airbag as required for each type of
impact.

•The ORC also 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 listed above except the knee bolster, the instru-
ment panel, and the steering wheel and column. If the
key is in the LOCK position, in the ACC position, or
not in the ignition, the airbags are not on and they will
not inflate.
•The ORC also turns on the Airbag Warning
Light in the instrument panel for six to eight
seconds as 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 continu-
ously. 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.
•TheDriver and Front Passenger Airbag/Inflator
Unitsare located in the center of the steering wheel
and the passenger 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 colli-
sion severity. The steering wheel hub trim cover, and
the upper passenger 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 to 70
ms. This is about half of the time that 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.
•TheKnee Impact Bolstershelp protect the knees of
the driver and the front passenger and position every-
one for the best interaction with the front airbag.
•TheSupplemental Side Impact SRS Side Curtain
Airbagsare designed to activate only in certain side
collisions. When the ORC (with side impact option)
detects a collision requiring the side curtain airbag to
inflate, it signals the inflators on the crash side of thevehicle. A quantity of nontoxic gas is generated to
inflate the side curtain airbag. The inflating side cur-
tain airbag pushes the outside edge of the headliner
out of the way and covers the window. The airbag
inflates in about 30 ms (about one-quarter of the time
that 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 side
curtain airbag inflates. This especially applies to chil-
dren. The side curtain airbag is only about 3-1/2 in (9
cm) thick when it is inflated.
•TheSupplemental Front Seat Mounted Side Airbags
are designed to activate only in certain side collisions.
When the ORC (with side impact option) detects a
collision requiring the front seat mounted side airbag
to inflate, it signals the inflators on the crash side of the
vehicle. A quantity of nontoxic gas is generated to
inflate the front seat mounted side airbag. The inflat-
ing front seat mounted side airbag pushes through the

seam in the seat’s trim cover and opens into the space
between the occupant and the door. The airbag inflates
at a very high speed and with enough force to injure
you if you are not belted and seated properly, or if
items are positioned in the area where the front seat
mounted side airbag inflates. This especially applies to
children.
The following requirements must be strictly adhered
to:
•Do not make any modifications to the front seat
components, assembly, or to the seat cover in any
way.
•Do not use prior or future model year seat covers
not designated for the specific model being re-
paired. Always use the correct seat cover specified
for the vehicle.
•Do not replace the seat cover with an aftermarket
seat cover.
•Do not add a secondary seat cover other than those
approved by DaimlerChrysler/Mopar.
•At no time should any supplemental restraint sys-
tem (SRS) component or SRS related component or
fastener be modified or replaced with any part
except those which are approved by
DaimlerChrysler/Mopar.

WARNING!
Unapproved modifications or service procedures to
the front seat assembly, its related components, or
seat cover may inadvertently change the airbag de-
ployment in case of a frontal crash. This could result
in death or serious injury to the driver or front seat
passenger if the vehicle is involved in an accident. A
modified vehicle may not comply with required
Federal Motor Vehicle Safety Standards (FMVSS).
If a Deployment Occurs
The airbag system is designed to deploy when the ORC
detects a moderate to severe collision to help restrain the
driver and front passenger and then to 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 that deploys the airbags, any or
all of the following may occur:
•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.

•As 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 irrita-
tion, move to fresh air. If the irritation continues, see your
doctor. If these particles settle on your clothing, follow the
garment manufacturer’s instructions for cleaning.
•It is not advisable to drive your vehicle after the airbags
have been deployed. If you are involved in another
collision, the airbags will not be in place to protect you.
WARNING!
Deployed airbags can’t protect you in another colli-
sion. Have the airbags replaced by an authorized
dealer as soon as possible.
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:
•Cuts off fuel to the engine.
•Flashes hazard lights.
•Turns on the interior lights, which remain on as long as
the battery has power or until the ignition key is
removed.
•Unlocks the doors automatically.
NOTE:The interior lights can only be deactivated if the
key is removed from the ignition switch or the vehicle is
driven.

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 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 passenger side of the instrument
panel. Do not modify the front bumper, vehicle
body structure, or frame.
•You need proper knee impact protection in a
collision. Do not mount or locate any aftermarket
equipment on or behind the knee impact bolster.
•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 airbags.
NOTE:Perchlorate Material — special handling may ap-
ply. See www.dtsc.ca.gov/hazardouswaste/perchlorate.
Airbag Warning Light
You will want to have the airbags ready to
inflate for your protection in an impact. While
the airbag system is designed to be mainte-
nance free, if any of the following occurs, have
an authorized dealer service the system promptly:
•The Airbag Warning Light does not come on or flickers
during the six to eight seconds when the ignition
switch is first turned ON.
•The light remains on or flickers after the six to eight
second interval.
•The 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 five seconds of specific vehicle data param-
eters (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 deploy-
ment. 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 beused 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
