Sometimes, however, despite
the best intentions of all
concerned, misunderstandings
can occur. If your concern has
not been resolved to your
satisfaction, the following
steps should be taken:
STEP ONE : Discuss your
concern with a member of

quickly resolved at that level.

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

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

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.

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) -

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.

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.
