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.
