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), Federal
Emission, Extended
Powertrain or Electric 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”
produced for new vehicles
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 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, insurancecoverage, 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.

Cadillac CT4 Owner Manual (GMNA-Localizing-U.S./Canada-16500442) -
2023 - CRC - 5/5/22
492 Customer Information
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 limiting
compensation for damage
repairs by using aftermarket
collision parts. Some insurance
companies will not specify
aftermarket collision parts.
When purchasing insurance,
we recommend that you
ensure that the vehicle will be
repaired with GM original
equipment collision parts.
If such insurance coverage is
not available from your
current insurance carrier,
consider switching to another
insurance carrier.
If the vehicle is leased, the
leasing company may require
you to have insurance that
ensures repairs with Genuine
GM Original Equipment
Manufacturer (OEM) parts or
Genuine Manufacturer
replacement parts. Read the
lease carefully, as you may be
charged at the end of the
lease for poor quality repairs.

If a Crash Occurs
If there has been an injury, call
emergency services for help.
Do not leave the scene of a
crash until all matters have
been taken care of. Move the
vehicle only if its position puts
you in danger, or you are
instructed to move it by a
police officer.
Give only the necessary
information to police and other
parties involved in the crash.
For emergency towing, see
Roadside Assistance Program
0487.
Gather the following
information:
.Driver name, address, and
telephone number
.Driver license number
.Owner name, address, and
telephone number
.Vehicle license plate number
.Vehicle make, model, and
model year
.Vehicle Identification
Number (VIN)
.Insurance company and
policy number
.General description of the

What Will You See after an
Airbag Inflates? 064.
Managing the Vehicle
Damage Repair Process
In the event that the vehicle
requires damage repairs, GM
recommends that you take an
active role in its repair. If you
have a pre-determined repair
facility of choice, take the
vehicle there, or have it towed
there. Specify to the facility
that any required replacement
collision parts be original equipment parts, either new
Genuine GM parts or recycled
original GM parts. Remember,
recycled parts will not be
covered by the GM vehicle
warranty.
Insurance pays the bill for the
repair, but you must live with
the repair. Depending on your
policy limits, your insurance
company may initially value the
repair using aftermarket parts.
Discuss this with the repair
professional, and insist on
Genuine GM parts. Remember,
if the vehicle is leased, you
may be obligated to have the
vehicle repaired with Genuine
GM parts, even if your
insurance coverage does not
pay the full cost.
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

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 thevehicle 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 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:
.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,

Cadillac CT4 Owner Manual (GMNA-Localizing-U.S./Canada-16500442) -
2023 - CRC - 5/5/22
498 Customer Information
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
permitted 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.
OnStar
If the vehicle is equipped with
OnStar and has an active
service plan, additional data
may be collected and
transmitted through theOnStar system. This includes
information about the vehicle’s
operation; collisions involving
the vehicle; the use of the
vehicle and its features,
including infotainment; and the
location and approximate GPS
speed of the vehicle. Refer to
the OnStar Terms and
Conditions and Privacy
Statement on the OnStar
website.

Information

Infotainment System
If the vehicle is equipped with
a navigation system as part of
the infotainment system, use
of the system may result in
the storage of destinations,
addresses, telephone
numbers, and other trip
information. See the
infotainment section for
information on stored data
and for deletion instructions.
