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 partswith 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.
Aftermarket collision parts are also
available. These are made by
companies other than GM and may
not have been tested for the vehicle.
As a result, these parts may fit poorly,
exhibit premature durability/corrosion
problems, and may not perform
properly in subsequent collisions.
Aftermarket parts are not covered by
the GM New Vehicle Limited
Warranty, and any vehicle failure
related to such parts is not covered by
that warranty.
Repair Facility
GM also recommends that you choose
a collision repair facility that meets
your needs before you ever need
collision repairs. Your dealer may have
a collision repair center with
GM-trained technicians and
state-of-the-art equipment, or be able
to recommend a collision repair center
that has GM-trained technicians and
comparable equipment.
Insuring the Vehicle
Protect your investment in the GM
vehicle with comprehensive and
collision insurance coverage. There are
significant differences in the quality of
coverage afforded by various
insurance policy terms. Many
insurance policies provide reduced
protection to the GM vehicle by

410 CUSTOMER INFORMATION
If another party's insurance company
is paying for the repairs, you are not
obligated to accept a repair valuation
based on that insurance company's
collision policy repair limits, as you
have no contractual limits with that
company. In such cases, you can have
control of the repair and parts choices
as long as the cost stays within
reasonable limits.

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 or untrusted networks (such
as Bluetooth, WIFI or similartechnology). 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:
.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,
