Vehicle Data Recording and Privacy
Your vehicle has a number of computers that record information about how the vehicle is operating and how it is driven. For example, the vehicle uses computer modules to control and monitor engine and transmission performance, to monitor the status of airbag deployment systems and to deploy them in a crash, and, if equipped, to provide antilock braking system assistance to the driver. These modules may store data to help the dealer technician service the vehicle. Some modules may also store data on how the vehicle is operated, such as fuel economy or average speed. These modules may also store personal preferences, such as radio presets, seat positions, and temperature settings.
Event Data Recorders
This vehicle is equipped with an event data recorder (EDR). The main purpose of the EDR is to record, in certain crash or near-crash-like situations, such as an airbag deployment or hitting a road obstacle, data that will assist in understanding how the vehicle's systems performed. The EDR is designed to record data related to vehicle dynamics and safety systems for a short period of time, typically 30 seconds or less. The EDR in this vehicle is 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 depressing the accelerator and/or brake pedal; and,
- How fast the vehicle was traveling.
These data can help provide a better understanding of the circumstances in which crashes and injuries occur.
EDR data are recorded by your vehicle only if a non-trivial crash situation occurs; no data are recorded by the EDR under normal driving conditions and no personal data (e.g., name, gender, age, and crash location) are recorded. However, other parties, such as law enforcement, could combine the EDR data with the type of personally identifying data routinely acquired during a crash investigation.
To read data recorded by an EDR, special equipment is required, and access to the vehicle or EDR is needed. In addition to the vehicle manufacturer, other parties, such as law enforcement, that have the special equipment, can read the information if they have access to the vehicle or the EDR.
GM will not access this data 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 by the police or a similar government agency; as part of GM's defense of litigation, through the discovery process; or as otherwise required by law. Data that GM collects or receives may also be used for GM research purposes or may be made available for other research purposes when necessary, and the data will not be linked to a specific vehicle or vehicle owner.
OnStar
If the vehicle is equipped with OnStar and has an active service plan, additional data may be collected through the OnStar system. This includes information about vehicle operation; crashes involving the vehicle; use of the vehicle and its features; and, in certain situations, the vehicle's location and approximate GPS speed. Refer to the OnStar Terms and Conditions and Privacy Statement on the OnStar website.
See OnStar for additional information.
Infotainment System
If the vehicle is equipped with a navigation system as part of the infotainment system, use of the system may result in storage of destinations, addresses, phone numbers, and other trip information. Refer to the infotainment system manual for information on stored data and for instructions on deleting it.
