Event Data Recorders
Some information about your vehicle’s
performance and how it is driven may be recorded
on various modules if a crash occurs. Some
people refer to these modules asevent data
recorders (EDRs). These modules may record
several seconds of pre-crash and crash data,
such as data related toengine speed, brake
application, throttle position, vehicle speed,
yaw rate, steering wheel angle, lateral
acceleration, safety belt usage, airbag
readiness, airbag performanceandthe severity
of the collision.Unlike the flight data recorders
on airplanes, these modules do not record
sounds or conversations.To retrieve this data, special equipment and
access to the vehicle or the module that stores
the data are required. Certain data may also
be sent to or retrieved by OnStar®(see below).
GM will not access this information or share it with
others except: with the consent of the vehicle
owner or, if the vehicle is leased, with the consent
of the lessee; in response to an official request
of police or similar government office; as part
of GM’s defense of litigation through the discovery
process; or, as required by law. Data that
GM collects or receives may also be used for
GM research needs or may be made available to
others for research purposes, where a need is
shown and the data is not tied to a specific vehicle
or vehicle owner.
Others may be able to retrieve this data if they
have access to the vehicle and have the special
equipment necessary to download the data.
