414 CUSTOMER INFORMATION
Courtesy Transportation is not a part
of the New Vehicle Limited Warranty.
A separate booklet entitled“Limited
Warranty and Owner Assistance
Information ”furnished with each new
vehicle provides detailed warranty
coverage information.
Transportation Options
Warranty service can generally be
completed while you wait. However,
if you are unable to do so, your dealer
may offer the following transportation
options:
Shuttle Service
This includes one-way or round-trip
shuttle service within reasonable time
and distance parameters of your
dealer's area.
Public Transportation or Fuel
Reimbursement
If overnight warranty repairs are
needed, and public transportation is
used, the expense must be supported
by original receipts and within the
maximum amount allowed by GM for
shuttle service. If U.S. customers
arrange their own transportation, limited reimbursement for reasonable
fuel expenses may be available. Claim
amounts should reflect actual costs
and be supported by original receipts.
See your dealer for information.
Courtesy Rental Vehicle
For an overnight warranty repair, the
dealer may provide an available
courtesy rental vehicle or provide for
reimbursement of a rental vehicle.
Reimbursement is limited and must
be supported by original receipts as
well as a signed and completed 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. Additional fees such
as fuel usage charges, taxes, levies,
usage fees, excessive mileage, or rental
usage beyond the completion of the
repair are also your responsibility.
It may not be possible to provide a
like vehicle as a courtesy rental.
Additional Program Information
All program options, such as shuttle
service, may not be available at every
dealer. Contact your dealer for specific
availability.
General Motors reserves the right to
unilaterally modify, change,
or discontinue Courtesy
Transportation at any time and to
resolve all questions of claim
eligibility pursuant to the terms and
conditions described herein at its sole
discretion.
Collision Damage Repair
If the vehicle is involved in a collision
and it is damaged, have the damage
repaired by a qualified technician
using the proper equipment and
quality replacement parts. Poorly
performed collision repairs diminish
the vehicle resale value, and safety
performance can be compromised in
subsequent collisions.
Collision Parts
Genuine GM Collision parts are new
parts made with the same materials
and construction methods as the parts

CUSTOMER INFORMATION 419
Vehicle Data Recording
and Privacy
The vehicle has a number of
computers that record information
about the vehicle’s performance and
how it is driven. For example, the
vehicle uses computer modules to
monitor and control engine and
transmission performance, to monitor
the conditions for airbag deployment
and deploy them in a crash, and,
if equipped, to provide antilock
braking to help the driver control the
vehicle. These modules may store data
to help the dealer technician service
the vehicle. Some modules may also
store data about how the vehicle is
operated, such as rate of fuel
consumption or average speed. These
modules may retain personal
preferences, such as radio presets, seat
positions, and temperature settings.
Event Data Recorders
This vehicle is equipped with an event
data recorder (EDR). The main
purpose of an EDR is to record, in
certain crash or near crash-likesituations, such as an air bag
deployment or hitting a road obstacle,
data that will assist in understanding
how a vehicle’s systems performed.
The EDR is designed to record data
related to vehicle dynamics and safety
systems for a short period of time,
typically 30 seconds or less. The EDR
in this vehicle is designed to record
such data as:
.
How various systems in your
vehicle were operating;
. Whether or not the driver and
passenger safety belts were
buckled/fastened;
. How far (if at all) the driver was
depressing the accelerator and/or
brake pedal; and,
. How fast the vehicle was traveling.
These data can help provide a better
understanding of the circumstances in
which crashes and injuries occur.
Note
EDR data are recorded by your vehicle
only if a non-trivial crash situation
occurs; no data are recorded by the
EDR under normal driving conditions
and no personal data (e.g., name, gender, age, and crash location) are
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 these 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 by 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 specific vehicle or vehicle owner.
