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:
•
A 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.
•
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.
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
