GMC Hummer H3 2008 Owner's Handbook Manual page 328

Law enforcement agencies or
others may have equipment that
can retrieve the information if they
have access to the vehicle or to the
device that stores the data.
While no personal data is recorded
by the event data recorder, law
enforcement agencies or others
may combine the data stored by
your vehicle with the personal
information routinely acquired
during a crash investigation.
GM will only access this informa-
tion with the consent of the vehi-
cle owner or lessee, in response
to an official request of police or
similar government office, as part
of GM's defense of litigation, 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.
Section 5
Some vehicles use radio frequency
identification technology for
features such as tyre pressure
monitoring and keyless access
systems. This technology does not
use or record personal information
or link to any other system
containing this type of
information.
