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. 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 • 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 confidentiality is to be maintained and need is shown, or • share summary data which is not tied to a specific 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. • with the consent of the vehicle owner or, if the vehicle is leased, with the consent of the lessee, 7-9
