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
travelingThis 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.
