Courtesy Rental Vehicle
Your dealer may arrange to provide you with a courtesy
rental vehicle or reimburse you for a rental vehicle
that you obtain if your vehicle is kept for a warranty
repair. Reimbursement will be limited to a maximum
amount per day and must be supported by receipts. This
requires that you sign and complete a rental agreement
and meet state, local and rental vehicle provider
requirements. Requirements vary and may include
minimum age requirements, insurance coverage, credit
card, etc. You are responsible for fuel usage charges
and may also be responsible for taxes, levies,
usage fees, excessive mileage or rental usage beyond
the completion of the repair.
Generally it is not possible to provide a like-vehicle as a
courtesy rental.

Bumper-to-Bumper warranty coverage period, but it is not
part of the New Vehicle Limited Warranty. A separate

Vehicle Data Collection and Event
Data Recorders
Your vehicle, like other modern motor vehicles, has a
number of sophisticated computer systems that monitor
and control several aspects of the vehicle’s performance.
Your vehicle uses on-board vehicle computers to monitor
emission control components to optimize fuel economy,
to monitor conditions for airbag deployment and, if so
equipped, to provide anti-lock braking and to help the
driver control the vehicle in difficult driving situations.
7-8

Some information may be stored during regular
operations to facilitate repair of detected malfunctions;
other information is stored only in a crash event by
computer systems, such as those commonly called event
data recorders (EDR).
In a crash event, computer systems, such as the Airbag
Sensing and Diagnostic Module (SDM) in your vehicle
may record information about the condition of the vehicle
and how it was operated, such as data related to engine
speed, brake application, throttle position, vehicle speed,
safety belt usage, airbag readiness, airbag performance,
and the severity of a collision. If your vehicle is equipped
with Quadrasteer or StabiliTrak
®, steering performance,
including yaw rate, steering wheel angle, and lateral
acceleration, is also recorded. This information has been
used to improve vehicle crash performance and may be
used to improve crash performance of future vehicles and
driving safety. Unlike the data recorders on many
airplanes, these on-board systems do not record sounds,
such as conversation of vehicle occupants.
To read this information, special equipment is needed
and access to the vehicle or the device that stores
the data 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 the device
that stores the data.
If your vehicle is equipped with OnStar
®, please check
the OnStar®subscription service agreement or
manual for information on its operations and data
collection.
