Event Data Recorders
This vehicle has an Event Data Recorder (EDR). Themain purpose of an EDR is to record, in certain crash ornear crash-like situations, such as an airbag deploymentor hitting a road obstacle, data that will assist inunderstanding how a vehicle’s systems performed. TheEDR is designed to record data related to vehicledynamics and safety systems for a short period of time,typically 30 seconds or less. The EDR in this vehicleis designed to record such data as:
•How various systems in your vehicle were operating
•Whether or not the driver and passenger safety
belts were buckled/fastened
•How far, if at all, the driver was pressing the
accelerator and/or brake pedal
•How fast the vehicle was traveling
This data can help provide a better understanding of thecircumstances in which crashes and injuries occur.
Important:EDR data is recorded by your vehicle only ifa non-trivial crash situation occurs; no data is recorded bythe EDR under normal driving conditions and no personaldata (e.g., name, gender, age, and crash location) isrecorded. However, other parties, such as lawenforcement, could combine the EDR data with the typeof personally identifying data routinely acquired during acrash investigation.
To read data recorded by an EDR, special equipment isrequired, and access to the vehicle or the EDR is needed.In addition to the vehicle manufacturer, other parties,such as law enforcement, that have the specialequipment, can read the information if they have accessto the vehicle or the EDR.
GM will not access this data or share it with othersexcept: with the consent of the vehicle owner or, if thevehicle is leased, with the consent of the lessee; inresponse to an official request of police or similargovernment office; as part of GM’s defense of litigationthrough the discovery process; or, as required by law.Data that GM collects or receives may also be used forGM research needs or may be made available to othersfor research purposes, where a need is shown and thedata is not tied to a specific vehicle or vehicle owner.
