Maintenance Schedule 6-11

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.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. See alsoOnStar
®
System on page 2-39in this manual
for more information.
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.
