Transportation Options
Warranty service can generally be completed
while you wait. However, if you are unable to wait,
GM helps to minimize your inconvenience by
providing several transportation options.
Depending on the circumstances, your dealer can
offer you one of the following:
Shuttle Service
Shuttle Service is the preferred means of offering
Courtesy Transportation and participating
dealers can provide you with shuttle service to get
you to your destination with minimal interruption
of your daily schedule. This includes one-way
or round trip shuttle service within reasonable time
and distance parameters for the dealer’s area.
Public Transportation or Fuel
Reimbursement
If your vehicle requires warranty repairs, and
public transportation is used as “shuttle service,”
the reimbursement is limited to the associated
shuttle allowance (contact your dealer) and must
be supported by original receipts. In addition,
in the United States, should you arrangetransportation through a friend or relative, limited
reimbursement for reasonable fuel expenses
may be available. Claim amounts should reect
actual costs and be supported by original receipts.
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. Taxi reimbursement
may also be available if you meet the eligibility for
a courtesy rental and a rental vehicle is not
practical for your requirements. Rental and taxi
reimbursement will be limited (contact your dealer)
and must be supported by original receipts. This
requires that you sign and complete a rental
agreement and meet state/provincial, 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.

Vehicle Data Recording and
Privacy
Your GM vehicle has a number of sophisticated
computers that record information about the
vehicle’s performance and how it is driven. For
example, your vehicle uses computer modules to
monitor and control engine and transmission
performance, to monitor the conditions for airbag
deployment and deploy airbags in a crash and, if so
equipped, to provide anti-lock braking to help the
driver control the vehicle. These modules may store
data to help your dealer/retailer technician service
your vehicle. Some modules may also store data
about how you operate the vehicle, such as rate of
fuel consumption or average speed. These
modules may also retain the owner’s personal
preferences, such as radio pre-sets, seat positions,
and temperature settings.
Event Data Recorders
Some information about your vehicle’s
performance and how it is driven may be recorded
on various modules if a crash occurs. Some
people refer to these modules asevent data
recorders (EDRs). These modules may record
several seconds of pre-crash and crash data, such
as data related toengine speed, brake
application, throttle position, vehicle speed,
yaw rate, steering wheel angle, lateral
acceleration, safety belt usage, airbag
readiness, airbag performanceandthe severity
of the collision.Unlike the ight data recorders
on airplanes, these modules do not record sounds
or conversations.
To retrieve this data, special equipment and
access to the vehicle or the module that stores the
data are required. Certain data may also be
sent to or retrieved by OnStar
®(see below). GM
will not access this information 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.
