Vehicle Data Recording and
Privacy
Your GM vehicle has a number of sophisticated
computers that record information about the
vehicle’s performance and how it is driven.
For example, your vehicle uses computer modules
to monitor and control engine and transmission
performance, to monitor the conditions for airbag
deployment and deploy airbags in a crash and,
if so equipped, to provide anti-lock braking to help
the driver control the vehicle. These modules may
store data to help your dealer/retailer technician
service your vehicle. Some modules may also store
data about how you operate the vehicle, such as
rate of fuel consumption or average speed. These
modules may also retain the owner’s personal
preferences, such as radio pre-sets, seat positions,
and temperature settings.
432

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 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.
