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 unavailable.
NOTE:
² A near-deployment event occurs when the airbag
sensor detects severe vehicle deceleration usually indicative
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 complete
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 performance.
In addition to crash investigations initiated by
DaimlerChrysler Corporation, such investigations may
be requested by customers, insurance carriers, government
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
data that does not identify particular vehicles or crashes
may be released for incorporation in aggregate crash
databases, such as those maintained by the US government
and various states. Data of a potentially sensitive
nature, such as would identify a particular driver, vehicle,
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:
² Diagnostic trouble code(s) and warning lamp status
for electronically-controlled safety systems, including
the airbag system
² Airbag disable lamp status (if equipped)
² Time of airbag deployment (in terms of ignition
cycles and vehicle mileage)
² Airbag deployment level (if applicable)
² Impact acceleration and angle
² Seat belt status
² Brake status (service and parking brakes)
² Accelerator status (including vehicle speed)
² Engine control status (including engine speed)
² Transmission gear selection
² Cruise control status
² Traction/stability control status
² Tire pressure monitoring system status
