Removing and Replacing the
Floor Mats
The driver side floor mat is held in
place by two button-type retainers.
1. Pull up on the rear of the driverside floor mat to unlock each
retainer and remove.
2. Reinstall by lining up the floor mat retainer openings over the carpet
retainers and snapping into
position. 3. Make sure the floor mat is properly
secured in place. Verify the floor
mat does not interfere with the
pedals.
Cleaning Rubber Floor Mats
(All-Weather Mats and Floor
Liners)
{Warning
Do not use cleaners that contain
silicone, wax-based products,
or cleaners that increase gloss on
rubber floor mats/liners. These
cleaners can permanently change
the appearance and feel of the
rubber and can make the floor
mats/liners slippery. Your foot
could slip while operating the
vehicle, and you could lose control,
resulting in a crash. You or others
could be injured.
Use a soft cloth and/or a brush
dampened with water to remove dust
and loose dirt. For more thorough
cleaning, use a mild soap solution.

Customer Information
Customer Satisfaction
Procedure
Your satisfaction and goodwill are
important to your dealer and to
Cadillac. Normally, any concerns with
the sales transaction or the operation
of the vehicle will be resolved by your
dealer's sales or service departments.
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 dealership
management. Normally, concerns can
be quickly resolved at that level. If the
matter has already been reviewed with
the sales, service or parts manager,
contact the owner of your dealership
or the general manager.

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. Thesemodules 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 vehicleelectronic 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;
