Event Data Recorders
This vehicle has an Event Data Recorder (EDR).
The main purpose of an EDR is to record, in
certain crash or near crash-like situations, such as
an air bag deployment or hitting a road obstacle,
data that will assist in understanding how a
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
•
How fast the vehicle was traveling
This data can help provide a better understanding
of the circumstances in which crashes and
injuries occur.
Important: EDR data is recorded by your vehicle
only if a non-trivial crash situation occurs; no
data is recorded by the EDR under normal driving
conditions and no personal data (e.g., name,
gender, age, and crash location) is 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 the 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 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 specific vehicle or vehicle owner.
