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 to
engine speed, brake application, throttle
position, vehicle speed, yaw rate, steering
wheel angle, lateral acceleration, safety belt
usage, airbag readiness, airbag performance
andthe severity of the collision.Unlike the
ight 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 specic 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.
