Customer Information 423
Vehicle Data
Recording and
Privacy
The vehicle has a number of
computers that record information
about the vehicle’s performance and
how it is driven. For example, the
vehicle uses computer modules to
monitor and control engine and
transmission performance, to
monitor the conditions for airbag
deployment and deploy them in a
crash, and, if equipped, to provide
antilock braking to help the driver
control the vehicle. These modules
may store data to help the dealer
technician service the vehicle.
Some modules may also store data
about how the vehicle is operated,
such as rate of fuel consumption or
average speed. These modules may
retain personal preferences, such as
radio presets, seat positions, and
temperature settings.
Event Data Recorders
This vehicle is equipped with 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; and,
. How fast the vehicle was
traveling. These data can help provide a
better understanding of the
circumstances in which crashes and
injuries occur.
Note
EDR data are recorded by your
vehicle only if a non-trivial crash
situation occurs; no data are
recorded by the EDR under normal
driving conditions and no personal
data (e.g., name, gender, age, and
crash location) are 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.

428 OnStar
.PressQto speak with an
Advisor.
OnStar or connected services
cannot work unless the vehicle is in
a place where OnStar has an
agreement with a wireless service
provider for service in that area. The
wireless service provider must also
have coverage, network capacity,
reception, and technology
compatible with OnStar or
connected services. Service
involving location information about
the vehicle cannot work unless GPS
signals are available, unobstructed,
and compatible with the OnStar
hardware. OnStar or connected
services may not work if the OnStar
equipment is not properly installed
or it has not been properly
maintained. If equipment or software
is added, connected, or modified,
OnStar or connected services may
not work. Other problems beyond
the control of OnStar —such as
hills, tall buildings, tunnels, weather,
electrical system design and
architecture of the vehicle, damage to the vehicle in a crash, or wireless
phone network congestion or
jamming
—may prevent service.
