assistance cannot be provided
right away, the Roadside
Assistance advisor may give
permission to get local
emergency road service. You will
receive payment, up to $100,
after sending the original receipt
to Roadside Assistance.
Mechanical failures may be
covered, however any cost for
parts and labor for repairs not
covered by the warranty are the
owner responsibility.
Scheduling Service
Appointments
When the vehicle requires warranty
service, contact your dealer and
request an appointment. By
scheduling a service appointment
and advising the service consultant
of your transportation needs, your
dealer can help minimize your
inconvenience.
If the vehicle cannot be scheduled
into the service department
immediately, keep driving it until it
can be scheduled for service, unless, of course, the problem is
safety related. If it is, please call
your dealership, let them know this,
and ask for instructions.
If your dealer requests you to bring
the vehicle for service, you are
urged to do so as early in the work
day as possible to allow for
same-day repair.
Courtesy Transportation
Program
To enhance your ownership
experience, we and our participating
dealers are proud to offer Courtesy
Transportation, a customer support
program for vehicles with the
Bumper-to-Bumper (Base Warranty
Coverage period in Canada),
extended powertrain, and/or
hybrid-specific warranties in both
the U.S. and Canada.
Several Courtesy Transportation
options are available to assist in
reducing inconvenience when
warranty repairs are required.
Courtesy Transportation is not a
part of the New Vehicle Limited
Warranty. A separate manual
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. If U.S. customers arrange

13557845) - 2020 - CRC - 3/26/20
362 Customer Information
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, rental
vehicle insurance, 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 with which the vehicle was
originally built. Genuine GM
Collision parts are the best choice to
ensure that the vehicle's designed
appearance, durability, and safety
are preserved. The use of Genuine
GM parts can help maintain the GM
New Vehicle Limited Warranty.
Recycled original equipment parts
may also be used for repair. These
parts are typically removed from
vehicles that were total losses in
prior crashes. In most cases, the
parts being recycled are from
undamaged sections of the vehicle.
A recycled original equipment GM
part may be an acceptable choice to
maintain the vehicle's originally
designed appearance and safety
performance; however, the history of
these parts is not known. Such parts
are not covered by the GM New
Vehicle Limited Warranty, and any
related failures are not covered by
that warranty.

Customer Information 367
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 or used. 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 or to help GM
improve safety or features. 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.
Cybersecurity
GM collects information about the
use of your vehicle including
operational and safety related
information. We collect this
information to provide, evaluate,
improve, and troubleshoot our
products and services and to
develop new products and services.
The protection of vehicle electronics
systems and customer data from
unauthorized outside electronic
access or control is important to
GM. GM maintains appropriate
security standards, practices,
guidelines and controls aimed at
defending the vehicle and the
vehicle service ecosystem against
unauthorized electronic access,
detecting possible malicious activity
in related networks, and responding
to suspected cybersecurity incidents
in a timely, coordinated and effective
manner. Security incidents could
impact your safety or compromise
your private data. To minimize
security risks, please do not connect
your vehicle electronic systems to
unauthorized devices or connect
your vehicle to any unknown oruntrusted networks (such as
Bluetooth, WIFI or similar
technology). In the event you
suspect any security incident
impacting your data or the safe
operation of your vehicle, please
stop operating your vehicle and
contact your dealer.
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-like situations, 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:
