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.

234 Driving and Operating
{Warning
When driving off-road,
bouncing and quick changes
in direction can easily throw
you out of position. This
could cause you to lose
control and crash. You and
your passengers should
always wear seat belts.
Before Driving Off-Road
.Have all necessary
maintenance and service
work completed.
.Fuel the vehicle, fill fluid
levels, and check inflation
pressure in all tires, including
the spare, if equipped.
.Read all the information
about AWD vehicles in this
manual.
.Make sure all underbody
shields, if equipped, are
properly attached.
.Know the local laws that
apply to off-road driving.To gain more ground
clearance if needed, it may be
necessary to remove the front
fascia lower air dam. However,
driving without the air dam
reduces fuel economy.
Caution
Operating the vehicle for
extended periods without
the front fascia lower air
dam installed can cause
improper airflow to the
engine. Reattach the front
fascia air dam after off-road
driving.
Loading the Vehicle for
Off-Road Driving
{Warning
.Unsecured cargo on the
load floor can be tossed
about when driving over
rough terrain. You or your
passengers can be struck
by flying objects. Secure
the cargo properly.
(Continued)
Warning (Continued)
.Keep cargo in the cargo
area as far forward and as
low as possible. The
heaviest things should be
on the floor, forward of
the rear axle.
.Heavy loads on the roof
raise the vehicle's center
of gravity, making it more
likely to roll over. You can
be seriously or fatally
injured if the vehicle rolls
over. Put heavy loads
inside the cargo area, not
on the roof.
For more information about
loading the vehicle, see
Vehicle Load Limits 0242.
Environmental Concerns
.Always use established
trails, roads, and areas that
have been set aside for
public off-road recreational
driving and obey all posted
regulations.

16412876) - 2023 - CRC - 3/25/22
238 Driving and Operating
or under the hood. These
accumulations can be a fire
hazard.
After operation in mud or
sand, have the brake linings
cleaned and checked. These
substances can cause glazing
and uneven braking. Check the
body structure, steering,
suspension, wheels, tires, and
exhaust system for damage
and check the fuel lines and
cooling system for any
leakage.
More frequent maintenance
service is required. See
Maintenance Schedule0425.
Driving on Wet Roads
Rain and wet roads can
reduce vehicle traction and
affect your ability to stop and
accelerate. Always drive
slower in these types of
driving conditions and avoid
driving through large puddles
and deep-standing or flowing
water.
{Warning
Wet brakes can cause
crashes. They might not
work as well in a quick stop
and could cause pulling to
one side. You could lose
control of the vehicle.
After driving through a large
puddle of water or a car/
vehicle wash, lightly apply
the brake pedal until the
brakes work normally.
Flowing or rushing water
creates strong forces.
Driving through flowing
water could cause the
vehicle to be carried away.
If this happens, you and
other vehicle occupants
could drown. Do not ignore
police warnings and be very
cautious about trying to
drive through flowing water.
Hydroplaning
Hydroplaning is dangerous.
Water can build up under the
vehicle's tires so they actually
ride on the water. This can
happen if the road is wet
enough and you are going fast
enough. When the vehicle is
hydroplaning, it has little or no
contact with the road.
There is no hard and fast rule
about hydroplaning. The best
advice is to slow down when
the road is wet.
Other Rainy Weather Tips
Besides slowing down, other
wet weather driving tips
include:
.Allow extra following
distance.
.Pass with caution.
.Keep windshield wiping
equipment in good shape.
.Keep the windshield washer
fluid reservoir filled.
.Have good tires with proper
tread depth. See Tires 0364.

Cadillac XT4 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
16412876) - 2023 - CRC - 3/25/22
Driving and Operating 239
.Turn off cruise control.
.Activate All-Wheel Drive
(AWD) mode. See Driver
Mode Control0269.
Hill and Mountain
Roads
Driving on steep hills or
through mountains is different
than driving on flat or rolling
terrain. Tips include:
.Keep the vehicle serviced
and in good shape.
.Check all fluid levels and
brakes, tires, cooling system,
and transmission.
.Shift to a lower gear when
going down steep or long
hills.
{Warning
Using the brakes to slow the
vehicle on a long downhill
slope can cause brake
overheating, can reduce
brake performance, and
could result in a loss of
(Continued)
Warning (Continued)
braking. Shift the
transmission to a lower gear
to let the engine assist the
brakes on a steep downhill
slope.
{Warning
Coasting downhill in
N (Neutral) or with the
ignition off is dangerous.
This can cause overheating
of the brakes and loss of
steering assist. Always have
the engine running and the
vehicle in gear.
.Drive at speeds that keep
the vehicle in its own lane.
Do not swing wide or cross
the center line.
.Be alert on top of hills;
something could be in your
lane (e.g., stalled car, crash).
.Pay attention to special road
signs (e.g., falling rocks area,
winding roads, long grades,
passing or no-passing zones)
and take appropriate action.
.Select All-Wheel Drive (AWD)
Mode. See Driver Mode
Control0269 and
All-Wheel Drive 0263.
Winter Driving
Driving on Snow or Ice
Caution
To avoid damage to the
wheels and brake
components, always clear
snow and ice from inside the
wheels and underneath the
vehicle before driving.
Snow or ice between the tires
and the road creates less
traction or grip, so drive
carefully. Wet ice can occur at
about 0 °C (32 °F) when
freezing rain begins to fall.

Parking over Things
That Burn
{Warning
Things that can burn could
touch hot exhaust parts
under the vehicle and ignite.
Do not park over papers,
leaves, dry grass, or other
things that can burn.
Active Fuel
Management
This vehicle's engine may be
equipped with Active Fuel
Management, which allows the
engine to operate on either all
of its cylinders, or in reduced
cylinder operation mode,
depending on the driving
conditions.
When less power is required,
such as cruising at a constant
vehicle speed, the system will
operate in reduced cylinder
operation mode, allowing the
vehicle to achieve better fuel
economy. When greater
power demands are required,
such as accelerating from a
stop, passing, or merging onto
a freeway, the system will
maintain full-cylinder
operation.
If the vehicle has an Active
Fuel Management indicator,
see Driver Information Center
(DIC) for more information on
using this display.
Extended Parking
It is best not to park with the
vehicle running. If the vehicle is
left running, be sure it will not
move and there is adequate
ventilation.
See Shifting Into Park
0254
and Engine Exhaust 0256.
