Airbag System Components
The airbag system consists of the following:
•Occupant Restraint Control (ORC) Module
•Airbag Warning Light
•Driver Airbag
•Passenger Airbag
•Front Seat-Mounted Side Airbags (If Equipped)
•Steering Wheel and Column
•Instrument Panel
•Interconnecting Wiring
•Knee Impact Bolsters
•Front Acceleration Sensors
•Remote Side Impact Acceleration Sensors (If
Equipped)
•Driver Seat Track Position Sensors
•Driver and Front Passenger Seat Belt Pretensioner
How The Airbag System Works
•
TheOccupant Restraint Control (ORC) Module de-
termines if a frontal or side collision is severe enough
to require the front and/or side airbags to inflate. The
front airbag inflators are designed to provide different
rates of airbag inflation from direction provided by the
ORC.
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 will not
inflate.

Also, the ORC turns on the Airbag Warning
Light 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. 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 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
immediately.
•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 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
are 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 bags inflate to their full size. The bags fully inflate
in about 50 to 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 front airbag gas is vented through the vent
holes in the sides of the airbag. The passenger front
airbag gas is vented through the vent holes in the sides
of the airbag. In this way, the airbags do not interfere
with your control of the vehicle.

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
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.
•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 pretensioner, and seat belt retractor assem-
bly, replaced by an authorized dealer as soon as
possible.

Enhanced Accident Response Feature
If the airbags deploy after an impact and the electrical
system remains functional, vehicles equipped with
power door locks will unlock automatically. The hazard
lights will flash and the fuel will be cut off to the engine.
In addition, after the vehicle has stopped moving, the
interior lights will illuminate to aid visibility and remain
lit until the ignition switch is turned off.
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 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 or vehicle body structure.
• You need proper knee impact protection in a
collision. Do not mount or locate any aftermarket
equipment on or behind the knee bolsters.
• 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.

Airbag Warning Light
You will want to have the airbag system ready to inflate
for your protection in an impact. The airbag system is
designed to be maintenance free. If any of the following
occurs, have an authorized dealer service the system
promptly:
•Does not come on during the six to eight seconds after
the ignition switch is first turned on.
•Remains on after the six to eight second interval.
•Comes on for any period of time 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, and up to a
quarter-second of high-speed deceleration data during
and/or after airbag deployment or near-deployment.
EDR data are ONLY recorded if an airbag deploys, or
nearly deploys, and are otherwise unavailable.
NOTE:
•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.
60 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE
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 leasee) 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 U.S. 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
Data Parameters that May Be Recorded:
•Diagnostic trouble code(s) and warning lamp status
for electronically-controlled safety systems, including
the airbag system
•Airbag disable lamp status (if equipped)
•Time
of airbag deployment (in terms of ignition
cycles and vehicle mileage)

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.
Infants and Child Restraints
•
Safety experts recommend that children ride
rearward-facing in the vehicle until they are at least
one-year oldandweigh at least 20 lbs (9 kg). Two
types of child restraints can be used rearward-facing:
infant carriers and “convertible” child seats.
•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). “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. Both types of
child restraints are held in the vehicle by the lap/
shoulder belt or the LATCH child restraint anchorage
system (Refer to LATCH — Child Seat Anchorage
System in this section.)
•Rearward-facing child seats must NEVERbe used in
the front seat of a vehicle with the front passenger
airbag unless the airbag is turned off. An airbag
deployment could cause severe injury or death to
infants in this position.

WARNING!
•Improper installation can lead to failure of an
infant or child restraint. It could come loose in a
collision. The child could be badly injured or
killed. Follow the manufacturer’s directions ex-
actly when installing an infant or child restraint.
•A rearward facing infant restraint should only be
used in a rear seat. A rearward facing infant
restraint in the front seat may be struck by a
deploying passenger airbag which may cause se-
vere or fatal injury to the infant.
Here are some tips for getting the most out of your child
restraint:
•Before buying any restraint system, make sure that it
has a label certifying that it meets all applicable Safety Standards. The manufacturer also recommends that
you try a child restraint in the vehicle seats where you
will use it before you buy it.
•The restraint must be appropriate for your child’s
weight and height. Check the label on the restraint for
weight and height limits.
•Carefully follow the instructions that come with the
restraint. If you install the restraint improperly, it may
not work when you need it.
•All seating positions (except for driver) have a auto-
matic locking retractor identified by a distinctive label.
The seat belts are designed to keep the lap portion
tight around the child restraint so that it is not
necessary to use a locking clip. For the seat belt with
the automatic locking retractor, pull the belt from the
retractor until there is enough to allow you to pass
through the child restraint and slide the latch plate
into the buckle. Then, pull the belt until it is fully
