Vehicle Data Collection and Event
Data Records
Your vehicle, like other modern motor vehicles, has a
number of sophisticated computer systems that monitor
and control several aspects of the vehicle's
performance. Your vehicle uses on-board vehicle
computers to monitor emission control components to
optimize fuel economy, to monitor conditions for
airbag deployment and, if so equipped, to provide
anti-lock braking and to help the driver control the
vehicle in difficult driving situations. Some information
may be stored during regular operations to facilitate
repair of detected malfunctions; other information
is stored only in a crash or near crash event by
computer systems commonly called event data
recorders (EDR).
In a crash or near crash event, computer systems, such
as the Airbag Sensing and Diagnostic Module (SDM)
in your vehicle may record information about the
condition of the vehicle and how it was operated, such
as engine speed, brake applications, throttle position,
vehicle speed, seat belt usage, airbag readiness, airbag
performance data, and the severity of a collision. This
information has been used to improve vehicle crash
performance and may be used to improve crash
performance of future vehicles and driving safety.
7-9

Unlike the data recorders on many airplanes, these
on-board systems do not record sounds, such as
conversation of vehicle occupants.
To read this information, special equipment is needed
and access to the vehicle or the SDM is required.
GM will not access information about a crash event or
share it with others other than
·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.
In addition, once GM collects or receives data, GM may
·use the data for GM research needs,
·make it available for research where appropriate
con®dentiality is to be maintained and need is
shown, or
·share summary data which is not tied to a speci®c
vehicle with non-GM organizations for research
purposes.
Others, such as law enforcement, may have access to
the special equipment that can read the information
if they have access to the vehicle or SDM.If your vehicle is equipped with OnStar, please check
the OnStar subscription service agreement or manual for
information on its operations and data collection.
Reporting Safety Defects
Reporting Safety Defects to the
United States Government
If you believe that your vehicle has a defect which could
cause a crash or could cause injury or death, you
should immediately inform the National Highway Traffic
Safety Administration (NHTSA), in addition to notifying
General Motors.
If NHTSA receives similar complaints, it may open an
investigation, and if it ®nds that a safety defect exists in
a group of vehicles, it may order a recall and remedy
campaign. However, NHTSA cannot become involved in
individual problems between you, your dealer or
General Motors.
To contact NHTSA, you may either call the Auto Safety
Hotline toll-free at 1-800-424-9393 (or 366-0123 in
the Washington, D.C. area) or write to:
NHTSA, U.S. Department of Transportation
Washington, D.C. 20590
You can also obtain other information about motor
vehicle safety from the hotline.
