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.
12-16 Customer Information
2008 - Pontiac G8 Owner Manual

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 specic vehicle or
vehicle owner.
OnStar®
If your vehicle has OnStar and you
subscribe to the OnStar services,
please refer to the OnStar Terms and
Conditions for information on data
collection and use.
Navigation System
If your vehicle has a navigation
system, use of the system may
result in the storage of destinations,
addresses, telephone numbers,
and other trip information. Refer to
the navigation system operating
manual for information on stored
data and for deletion instructions.
Radio Frequency
Identication (RFID)
RFID technology is used in some
vehicles for functions such as
tire pressure monitoring and ignition
system security, as well as in
connection with conveniences such
as key fobs for remote door
locking/unlocking and starting, and
in-vehicle transmitters for garage
door openers. RFID technology in
GM vehicles does not use or record
personal information or link with
any other GM system containing
personal information.
