1. Remove the compressorfrom its storage location.
See Storing the Tire
Sealant and Compressor
Kit 0446.
2. Remove the air only hose (10) and the power plug (9)
from the bottom of the
compressor.
3. Place the compressor on the ground near the
flat tire.
Make sure the tire valve
stem is positioned close to
the ground so the hose will
reach it.
4. Remove the valve stem cap from the flat tire by
turning it
counterclockwise.
5. Attach the air only hose (10) to the tire valve stem
by turning it clockwise until
tight.
6. Plug the power plug (9) into the accessory power
outlet in the vehicle. Unplug all items from other
accessory power outlets.
See Power Outlets
0101.
If the vehicle has an
accessory power outlet, do
not use the cigarette
lighter.
If the vehicle only has a
cigarette lighter, use the
cigarette lighter.
Do not pinch the power
plug cord in the door or
window.
7. Start the vehicle. The vehicle must be running
while using the air
compressor.
8. Press the on/off button (5) to turn the tire sealant and
compressor kit on.
The compressor will inflate
the tire with air only.
9. Inflate the tire to the recommended inflation
pressure using the
pressure gauge (8). The
recommended inflation
pressure can be found on the Tire and Loading
Information label. See Tire
Pressure
0422.
The pressure gauge (8)
may read higher than the
actual tire pressure while
the compressor is on. Turn
the compressor off to get
an accurate pressure
reading. The compressor
may be turned on/off until
the correct pressure is
reached.
Caution
If the recommended
pressure cannot be reached
after approximately
25 minutes, the vehicle
should not be driven farther.
The tire is too severely
damaged and the tire
sealant and compressor kit
cannot inflate the tire.

Locks
Locks are lubricated at the
factory. Use a de-icing agent
only when necessary, and
have the locks greased after
using. See Recommended
Fluids and Lubricants0474.
Washing the Vehicle
To preserve the vehicle finish,
wash it often and out of direct
sunlight.
Caution
Do not use
petroleum-based, acidic,
or abrasive cleaning agents
as they can damage the
vehicle's paint, metal,
or plastic parts. If damage
occurs, it would not be
covered by the vehicle
warranty. Approved cleaning
products can be obtained
(Continued)
Caution (Continued)
from your dealer. Follow all
manufacturer directions
regarding correct product
usage, necessary safety
precautions, and
appropriate disposal of any
vehicle care product.
Caution
Avoid using high-pressure
washes closer than 30 cm
(12 in) to the surface of the
vehicle. Use of power
washers exceeding
8 274 kPa (1,200 psi) can
result in damage or removal
of paint and decals. Automatic Car Wash
Caution
Automatic car washes can
cause damage to the
vehicle, wheels, ground
effects, and convertible top
(if equipped).
Do not use automatic car
washes due to lack of
clearance for the
undercarriage, wide rear
tires, and wheels.
Caution
To avoid damage to a matte
paint finish, do not use an
automatic car wash
equipped with brushes or
scrubbers. Only use
touchless automatic car
washes.
If using an automatic car wash,
follow the car wash
instructions. The windshield
wiper and rear window wiper,
if equipped, must be off.

Vehicle Care 461
Interior Care
To prevent dirt particle
abrasions, regularly clean the
vehicle's interior. Before using
cleaners, read and follow all
safety instructions on the
label. While cleaning the
interior, open the doors and
windows to get proper
ventilation. Newspapers or
dark garments can transfer
color to the vehicle’s interior.
Caution
Immediately remove
cleaners, hand lotions,
sunscreen, and insect
repellent from all interior
surfaces or permanent
damage may result.
Caution
Use cleaners specifically
designed for the surfaces
being cleaned to prevent
permanent damage to the(Continued)
Caution (Continued)
vehicle. Apply all cleaners
directly to a cleaning cloth.
Do not spray cleaners on
any switches or controls.
When using liquid soap
cleaners, follow the directions
on the specific cleaner or soap
solution for dilution
instructions.
Caution
To prevent damage:
.Never use a razor or any
other sharp object to
remove soil from any
interior surface
.Never use a brush with
stiff bristles.
.Never rub any surface
aggressively or with too
much pressure.
.Do not get any exposed
electrical components wet. (Continued)
Caution (Continued)
.Do not use laundry
detergents or dishwashing
soaps with degreasers. Do
not use solutions that
contain strong or
caustic soap.
.Do not heavily saturate
the upholstery when
cleaning.
.Do not use solvents or
cleaners containing
solvents.
.Do not use disinfecting
wipes that are scented or
contain bleach. Do not use
wipes or cleaners that
show a color transfer to
the wipe or change the
appearance of the interior
surface when used.
.Do not use scented or
gel-type hand sanitizers.
If hand sanitizer comes in
contact with interior
surfaces of the vehicle,
blot immediately and clean(Continued)

Caution (Continued)
with a soft cloth
dampened with a mild
soap and water solution.
Interior Glass
To clean, use a microfiber
cloth fabric dampened with
water. Wipe droplets left
behind with a clean dry cloth.
If necessary, use a commercial
glass cleaner after cleaning
with plain water.
Caution
To prevent scratching, never
use abrasive cleaners on
automotive glass. Abrasive
cleaners or aggressive
cleaning may damage the
rear window defogger.
Cleaning the windshield with
water during the first three to
six months of ownership will
reduce tendency to fog.
Speaker Covers
Vacuum around a speaker
cover gently, so that the
speaker will not be damaged.
Clean spots with water and
mild soap.
Coated Moldings
Coated moldings should be
cleaned.
.When lightly soiled, wipe
with a sponge or soft,
lint-free cloth dampened
with water.
.When heavily soiled, use
warm soapy water.
Vinyl/Rubber
If equipped with vinyl floor and
rubber floor mats, use a soft
cloth and/or brush dampened
with water to remove dust and
loose dirt. For more thorough
cleaning, use a mild soap and
water solution.
{Warning
Do not use cleaners that
contain silicone, wax-based
products, or cleaners that
increase gloss on vinyl/
rubber floor and mats.
These cleaners can
permanently change the
appearance and feel of the
vinyl/rubber and can make
the floor slippery. Your foot
could slip while operating
the vehicle, and you could
lose control, resulting in a
crash. You or others could
be injured.
Fabric/Carpet/Suede
Start by vacuuming the
surface using a soft brush
attachment. If a rotating
vacuum brush attachment is
being used, only use it on the
floor carpet. Before cleaning,
gently remove as much of the
soil as possible:

Cadillac CT4 Owner Manual (GMNA-Localizing-U.S./Canada-16500442) -
2023 - CRC - 5/4/22
Vehicle Care 463
.Gently blot liquids with a
paper towel. Continue
blotting until no more soil
can be removed.
.For solid soils, remove as
much as possible prior to
vacuuming.
To clean: 1. Saturate a clean, lint-free colorfast cloth with water.
Microfiber cloth is
recommended to prevent
lint transfer to the fabric
or carpet.
2. Remove excess moisture by gently wringing 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.
