.The TPMS sensor matching process
was not done or not completed
successfully after rotating the tires.
The malfunction light and the DIC
message should go off after
successfully completing the sensor
matching process. See "TPMS
Sensor Matching Process" later in
this section.
.One or more TPMS sensors are
missing or damaged. The
malfunction light and the DIC
message should go off when the
TPMS sensors are installed and the
sensor matching process is
performed successfully. See your
dealer for service.
.Replacement tires or wheels do not
match the original equipment tires
or wheels. Tires and wheels other
than those recommended could
prevent the TPMS from functioning
properly. SeeBuying New Tires
0 379.
.Operating electronic devices or
being near facilities using radio
wave frequencies similar to the
TPMS could cause the TPMS
sensors to malfunction. If the TPMS is not functioning
properly it cannot detect or signal a
low tire pressure condition. See your
dealer for service if the TPMS
malfunction light and DIC message
come on and stay on.
Tire Fill Alert (If Equipped)
This feature provides visual and
audible alerts outside the vehicle to
help when inflating an underinflated
tire to the recommended cold tire
pressure.
When the low tire pressure warning
light comes on:
1. Park the vehicle in a safe, level place.
2. Set the parking brake firmly.
3. Place the vehicle in P (Park).
4. Add air to the tire that is underinflated. The turn signal lamp
will flash.
When the recommended pressure
is reached, the horn sounds once
and the turn signal lamp will stop
flashing and briefly turn solid. Repeat these steps for all
underinflated tires that have
illuminated the low tire pressure
warning light.
{Warning
Overinflating a tire could cause the
tire to rupture and you or others
could be injured. Do not exceed the
maximum pressure listed on the
tire sidewall. See
Tire Sidewall
Labeling 0366 and
Vehicle Load Limits 0228.
If the tire is overinflated by more than
35 kPa (5 psi), the horn will sound
multiple times and the turn signal
lamp will continue to flash for several
seconds after filling stops. To release
and correct the pressure, while the
turn signal lamp is still flashing,
briefly press the center of the valve
stem. When the recommended
pressure is reached, the horn
sounds once.
If the turn signal lamp does not flash
within 15 seconds after starting to
inflate the tire, the tire fill alert has
not been activated or is not working.

404 VEHICLE CARE
2. Remove excess moisture by gentlywringing until water does not drip
from the cleaning cloth.
3. Start on the outside edge of the soil and gently rub toward the
center. Fold the cleaning cloth to a
clean area frequently to prevent
forcing the soil into the fabric.
4. Continue gently rubbing the soiled area until there is no longer any
color transfer from the soil to the
cleaning cloth.
5. If the soil is not completely removed, use a mild soap solution
followed only by plain water.
If the soil is not completely removed,
it may be necessary to use a
commercial upholstery cleaner or spot
lifter. Test a small hidden area for
colorfastness before using a
commercial upholstery cleaner or spot
lifter. If ring formation occurs, clean
the entire fabric or carpet.
After cleaning, use a paper towel to
blot excess moisture.Cleaning High Gloss Surfaces
and Vehicle Information and
Radio Displays
Use a microfiber cloth on high gloss
surfaces or vehicle displays. First, use
a soft bristle brush to remove dirt that
can scratch the surface. Then gently
clean by rubbing with a microfiber
cloth. Never use window cleaners or
solvents. Periodically hand wash the
microfiber cloth separately, using mild
soap. Do not use bleach or fabric
softener. Rinse thoroughly and air dry
before next use.
Caution
Do not attach a device with a
suction cup to the display. This may
cause damage and would not be
covered by the vehicle warranty.
Instrument Panel, Leather, Vinyl,
Other Plastic Surfaces, Low
Gloss Paint Surfaces, and
Natural Open Pore Wood
Surfaces
Use a soft bristle brush to remove
dust from knobs and crevices on the
instrument cluster. Use a soft
microfiber cloth dampened with water
to remove dust and loose dirt. For a
more thorough cleaning, use a soft
microfiber cloth dampened with a
mild soap and water solution.
Caution
Soaking or saturating leather,
especially perforated leather, as well
as other interior surfaces, may
cause permanent damage. Wipe
excess moisture from these surfaces
after cleaning and allow them to
dry naturally. Never use heat,
steam, or spot removers. Do not use
liquids that contain alcohol or
solvents on leather seats. Do not
use cleaners that contain silicone or
wax-based products. Cleaners (Continued)

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. 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
