Air Vents

Cadillac XT4 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
16412876) - 2023 - CRC - 3/25/22
226 Climate Controls
Adjustable air vents are in the
center and on the sides of the
instrument panel, and on the
rear of the center console
storage.
Move the slider knobs to
change the direction of or to
close off the airflow.
Operation Tips
.Clear away any ice, snow,
or leaves from air inlets at
the base of the windshield
that could block the flow of
air into the vehicle.
.Clear snow off the hood to
improve visibility and help
decrease moisture drawn
into the vehicle.
.Keep the path under the
front seats clear of objects
to help circulate the air
inside of the vehicle more
effectively.
.Use of non-GM approved
hood deflectors can
adversely affect the
performance of the system.Check with your dealer
before adding equipment to
the outside of the vehicle.
.Do not attach any devices to
the air vent slats. This
restricts airflow and may
cause damage to the air
vents.
Maintenance
Passenger
Compartment Air
Filter
The filter reduces dust, pollen,
and other airborne irritants
from outside air that is pulled
into the vehicle. The filter
should be replaced as part of
routine scheduled
maintenance. See
Maintenance Schedule
0425.
See your dealer regarding
replacement of the filter.
Service
All vehicles have a label
underhood that identifies the
refrigerant used in the vehicle.
The refrigerant system should
only be serviced by trained
and certified technicians. The
air conditioning evaporator
should never be repaired or
replaced by one from a
salvage vehicle. It should only
be replaced by a new
evaporator to ensure proper
and safe operation.
During service, all refrigerants
should be reclaimed with
proper equipment. Venting
refrigerants directly to the
atmosphere is harmful to the
environment and may also
create unsafe conditions
based on inhalation,
combustion, frostbite, or other
health-based concerns.
The air conditioning system
requires periodic maintenance.
See Maintenance Schedule
0 425.

When thehindicator is
illuminated, the system is
enabled.
Winter Cover
If equipped, the winter cover
can be used to enhance
heater performance in
extremely cold conditions
below −0 °C (32 °F). The winter
cover installs over the grille
and restricts airflow to the
engine compartment.
Usage Guidelines
The winter cover should only
be used while operating the
vehicle in extremely cold
temperatures or in heavy
snow for extended periods. In
these temperatures, the
vehicle does not need a large
amount of air to properly cool
the engine. When more airflow
is required to cool the vehicle,
the winter cover should not be
used. The following usage
guidelines will allow adequate
airflow for proper radiator and
air cooler performance:
.Do not use the winter cover
if towing a trailer. The
vehicle may overheat if the
radiator is covered while
towing.
.Do not modify the cover. The
winter cover does not cover
some sections of the front
of the vehicle to provide
enough airflow.
.Keep the underside of the
winter cover as clean as
possible. Remove monthly or
as necessary and clean away
dust and debris.
.Do not use the winter cover
above −0 °C (32 °F).
Use only a mild soap to clean.
Do not use harsh soap, strong
detergents, or vinyl
protectant/sealant type
products as they may damage
the special finish. Allow the
winter cover to dry completely
before reinstalling.
Installation Instructions
When first trying to fit the
cover, it may appear to be
undersized but will stretch
during installation to ensure a
tight fit. The initial installation
of the cover is best performed
when the winter cover
is warm.
1. Center grille cover and make sure that it is
positioned correctly.

2. Push plastic hooks back toengage grille slats. It is
recommended to start with
the lower hooks at the
center of the grille.
3. Repeat for all hooks to fully engage cover to grille.
For vehicles equipped with
a front license plate
bracket, only the outer
clips will be engaged on
the upper row. Ensure the
top center portion of the
cover is positioned
securely behind the license
plate bracket. 4. Make sure all clips remain
engaged during
installation. Cover should
be stretched to a tight fit
when properly installed.
Engine Heater
The engine heater, if available,
can help in cold weather
conditions at or below
−18 °C (0 °F) for easier starting
and better fuel economy
during engine warm-up. Plug in
the engine heater at least four
hours before starting the
vehicle. An internal thermostat
in the plug end of the cord will
prevent engine heater
operation at temperatures
above −18 °C (0 °F).
{Warning
Do not plug in the engine
block heater while the
vehicle is parked in a garage
or under a carport. Property
damage or personal injury
may result. Always park the
