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 or vehicle body structure.
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 an airbag system.NOTE:
Perchlorate Material ± special handling may ap-
ply, See www.dtsc.ca.gov/hazardouswaste/perchlorate
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:
²Does not come on during the 2.5 to 8 seconds after the
ignition switch is first turned on.
²Remains on after the 2.5 to 8 second interval.
²Flickers, or comes on and remains on for any period of
time while driving.
NOTE:If the speedometer, tachometer, or any engine
related gauges are not working, the airbag control mod-
ule may also be disabled. The airbags may not be ready
to inflate for your protection. Promptly check the fuse

block for blown fuses. Refer to ªFuse Panelº in Section 5
of this manual. 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 air bag deployment or near-
deployment. EDR data are ONLY recorded if an airbag
deploys, or nearly deploys, and are otherwise unavail-
able.
NOTE:
²A near-deployment event occurs when the airbag
sensor detects severe vehicle deceleration usually in-
dicative of a crash, but not severe enough to warrant
airbag deployment.
²Under 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.
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

2. Dry with a soft tissue.
Seat Belt Maintenance
Do not bleach, dye or clean the belts with chemical
solvents or abrasive cleaners. This will weaken the fabric.
Sun damage will also weaken the fabric.
If the belts need cleaning, use MopartTotal Clean, a mild
soap solution, or lukewarm water. Do not remove the
belts from the vehicle to wash them.
Replace the belts if they appear frayed or worn or if the
buckles do not work properly.
Dry with a soft tissue.
