Customer Information 13-21
This data can help provide a better
understanding of the circumstances
in which crashes and injuries occur.
Important:EDR data is recorded
by the 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. 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 by 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
specific vehicle or vehicle owner.
OnStar®
If the vehicle is equipped with an
active OnStar system, that system
may also record data in crash or
near crash‐like situations. The
OnStar Terms and Conditions
provides information on data
collection and use and is available
at www.onstar.com (U.S.) or
www.onstar.ca (Canada), or by
pressing the
Qbutton and
speaking to an advisor. See OnStar
Overview on page 14‑1 for more
information.
Navigation System
If the 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 manual for information on
stored data and for deletion
instructions.

Global Positioning
System (GPS)
.Obstruction of the GPS can
occur in a large city with tall
buildings; in parking garages;
around airports; in tunnels,
underpasses, or parking
garages; or in an area with very
dense trees. If GPS signals are
not available, the OnStar system
should still operate to call
OnStar. However, OnStar could
have difficulty identifying the
exact location.
.In emergency situations, OnStar
can use the last stored GPS
location to send to emergency
responders.
.A temporary loss of GPS can
cause loss of the ability to send
a Turn-by-Turn Navigation route.
The Advisor may give a verbal
route or may ask for a call back
after the vehicle is driven into an
open area.
Cellular and GPS Antennas
Avoid placing items over or near the
antenna to prevent blocking cellular
and GPS signal reception. Cellular
reception is required for OnStar to
send remote signals to the vehicle.
