To read this information, special equipment is needed
and access to the vehicle or the SDM is required.
GM will not access information about a crash event or
share it with others other than
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.
In addition, once GM collects or receives data, GM may
use the data for GM research needs,
make it available for research where appropriate
condentiality is to be maintained and need is
shown, or
share summary data which is not tied to a
specic vehicle with non-GM organizations for
research purposes.
Others, such as law enforcement, may have access to
the special equipment that can read the information
if they have access to the vehicle or SDM.
If your vehicle is equipped with OnStar
®, please check
the OnStar®subscription service agreement or manual
for information on its operations and data collection.

cause a crash or could cause injury or death, you
should immediately inform the National Highway Traffic

General Motors.
If NHTSA receives similar complaints, it may open an
investigation, and if it nds that a safety defect exists in
a group of vehicles, it may order a recall and remedy
campaign. However, NHTSA cannot become involved in
individual problems between you, your dealer, or
General Motors.
To contact NHTSA, you may either call the Auto Safety
Hotline toll-free at 1-800-424-9393 (or 366-0123 in
the Washington, D.C. area) or write to:
