Vehicle Data Recording and
Privacy
Your GM vehicle has a number of sophisticated
computers that record information about the vehicle’s
performance and how it is driven. For example, your
vehicle uses computer modules to monitor and control
engine and transmission performance, to monitor the
conditions for airbag deployment and deploy airbags in
a crash and, if so equipped, to provide antilock braking
to help the driver control the vehicle. These modules
may store data to help your dealer/retailer technician
service your vehicle. Some modules may also store
data about how you operate the vehicle, such as rate of
fuel consumption or average speed. These modules
may also retain the owner’s personal preferences, such
as radio pre-sets, seat positions, and temperature
settings.
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 airbag
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 pressing 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.
