Event Data Recorder (EDR)
In the event of an accident, your vehicle is designed to
record up to five 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 airbag deployment or near-deployment. EDR
data are ONLY recorded if an airbag deploys, or nearly
deploys, and are otherwise unavailable.
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 Chrysler LLC 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 Chrysler LLC, 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
Chrysler LLC (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 elec-
tronic 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 par-
ticular vehicles or crashes may be released for incorpo-
ration in aggregate crash databases, such as those main-
tained by the U.S. government and various states. Data of
