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 may
also 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 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.
During a moderate-to-severe rear impact the ORC
may deploy the seat belt pretensioners alone.
Also, the ORC turns on the AIRBAG warn-
ing light and PAD indicator light in the
instrument panel for 6 to 8 seconds for a
self-check when the ignition is first turnedon. After the self-check, the AIRBAG warning light
will turn off. The PAD indicator light will function
normally (Refer to9Passenger 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 continu-
ously. 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.
²TheOccupant Classification System (OCS)is part of
a Federally regulated safety system required for this
vehicle. It is designed to turn off the front passenger
airbag for occupants that weigh less than a very small
adult.

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 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.
²Do 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 including 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 approved seat accessories may be used. If it is
necessary to modify an advanced airbag system for persons with
disabilities, contact your authorized dealer.
²Do not place or hang any items such as add-on video players on
the right front passenger seat back. The additional weight may
cause the Occupant Classification System to be unable to cor-
rectly classify the right front occupant. This could allow the
passenger 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 bolsters/ driver inflatable knee blocker.
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.
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 maintenance free, if any of the following
occurs, have an authorized dealer service the system
immediately.
²The AIRBAG light does not come on during the 6 to 8
seconds when the ignition switch is first turned on.
²The light remains on after the 6 to 8 second interval.
²The light comes on and remains on while driving.
Event Data Recorder (EDR)
In the event of an airbag deployment, your vehicle is
designed to record up to 2-seconds of specific vehicle
data parameters (see list below) in an event data recorder
prior to the moment of airbag deployment. Please note
that such data are ONLY recorded if an airbag deploys,
and are otherwise unavailable. In conjunction with other
data gathered during a complete accident investigation,
the electronic data may be used by DaimlerChrysler and
others to learn more about the possible causes of crashes
and associated injuries in order to assess and improve
