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-

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.

Cadillac XT4 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
16412876) - 2023 - CRC - 3/25/22
240 Driving and Operating
Avoid driving on wet ice or in
freezing rain until roads can be
treated.
For Slippery Road Driving:
.Accelerate gently.
Accelerating too quickly
causes the wheels to spin
and makes the surface under
the tires slick.
.Turn on Traction Control.
See Traction Control/
Electronic Stability Control
0267.
.The Antilock Brake System
(ABS) improves vehicle
stability during hard stops,
but the brakes should be
applied sooner than when on
dry pavement. See Antilock
Brake System (ABS) 0264.
.Allow greater following
distance and watch for
slippery spots. Icy patches
can occur on otherwise clear
roads in shaded areas. The
surface of a curve or an
overpass can remain icy
when the surrounding roads are clear. Avoid sudden
steering maneuvers and
braking while on ice.
.Turn off cruise control.
.Select All-Wheel Drive (AWD)
Mode for vehicles equipped
with AWD. Select Snow/Ice
Mode for FWD only vehicles.
See Driver Mode Control
0
269 and
All-Wheel Drive 0263.
Cold Weather Mode
In very low temperatures, a
cold weather message may
display on the Driver
Information Center (DIC). The
engine speed, transmission
shift patterns, and cabin fan
speed may operate differently
to enable the vehicle to warm
up quicker. You can manually
override the cabin fan speed in
cold weather mode.
Blizzard Conditions
Stop the vehicle in a safe
place and signal for help. Stay
with the vehicle unless there is
help nearby. If possible, use Roadside Assistance. See
Roadside Assistance Program
0
439. To get help and keep
everyone in the vehicle safe:
.Turn on the hazard warning
flashers.
.Tie a red cloth to an outside
mirror.
{Warning
Snow can trap engine
exhaust under the vehicle.
This may cause exhaust
gases to get inside. Engine
exhaust contains carbon
monoxide (CO), which cannot
be seen or smelled. It can
cause unconsciousness and
even death.
If the vehicle is stuck
in snow:
.Clear snow from the base
of the vehicle, especially
any blocking the
exhaust pipe.

Driving and Operating 241
Warning (Continued)
.Open a window about
5 cm (2 in) on the vehicle
side that is away from the
wind, to bring in fresh air.
.Fully open the air outlets
on or under the
instrument panel.
.Adjust the climate control
system to circulate the air
inside the vehicle and set
the fan speed to the
highest setting. See
“Climate Control Systems.”
For more information about
CO, see Engine Exhaust
0 256.
To save fuel, run the engine
for short periods to warm the
vehicle and then shut the
engine off and partially close
the window. Moving about to
keep warm also helps.
If it takes time for help to
arrive, when running the
engine, push the accelerator
pedal slightly so the engine runs faster than the idle
speed. This keeps the battery
charged to restart the vehicle
and to signal for help with the
headlamps. Do this as little as
possible, to save fuel.
If the Vehicle Is Stuck
Slowly and cautiously spin the
wheels to free the vehicle
when stuck in sand, mud, ice,
or snow.
If stuck too severely for the
traction system to free the
vehicle, turn the traction
system off and use the rocking
method. See Traction Control/
Electronic Stability Control
0
267.
{Warning
If the vehicle's tires spin at
high speed, they can
explode, and you or others
could be injured. The vehicle
can overheat, causing an
engine compartment fire or
other damage. Spin the
(Continued)
Warning (Continued)
wheels as little as possible
and avoid going above
56 km/h (35 mph).
For All-Wheel Drive (AWD),
select Off-Road or AWD mode.
See Driver Mode Control
0 269 and
All-Wheel Drive 0263.
Rocking the Vehicle to Get
it Out
Turn the steering wheel left
and right to clear the area
around the front wheels. Turn
off any traction system. Shift
back and forth between
R (Reverse) and a low forward
gear, spinning the wheels as
little as possible. To prevent
transmission wear, wait until
the wheels stop spinning
before shifting gears. Release
the accelerator pedal while
shifting, and press lightly on
the accelerator pedal when
the transmission is in gear.
Slowly spinning the wheels in

the forward and reverse
directions causes a rocking
motion that could free the
vehicle. If that does not get
the vehicle out after a few
tries, it might need to be
towed out. If the vehicle does
need to be towed out, see
Transporting a Disabled
Vehicle0407.
Vehicle Load Limits
It is very important to know
how much weight the
vehicle can carry. This
weight is called the vehicle
capacity weight and
includes the weight of all
occupants, cargo, and all
nonfactory-installed
options. Two labels on the
vehicle may show how
much weight it may
properly carry, the Tire and
Loading Information label
and the Certification/Tire
label.
{Warning
Do not load the vehicle
any heavier than the
Gross Vehicle Weight
Rating (GVWR), or either
the maximum front or
rear Gross Axle Weight
Rating (GAWR). This can
cause systems to break
and change the way the
vehicle handles. This
could cause loss of
control and a crash.
Overloading can also
reduce stopping
performance, damage the
tires, and shorten the life
of the vehicle.Tire and Loading Information
Label
Example Label
A vehicle-specific Tire and
Loading Information label is
attached to the center
pillar (B-pillar). The tire and
loading information label
shows the number of
occupant seating
positions (1), and the
maximum vehicle capacity
weight (2) in kilograms and
pounds.

Cadillac XT4 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
16412876) - 2023 - CRC - 3/25/22
Driving and Operating 245
and seating positions. The
combined weight of the
driver, passengers, and
cargo should never exceed
the vehicle's capacity
weight.
Certification/Tire Label
Label Example
A vehicle-specific
Certification/Tire label is
attached to the center
pillar (B-pillar).
The label may show the
size of the vehicle's original
tires and the inflationpressures needed to obtain
the gross weight capacity
of the vehicle. The label
shows the gross weight
capacity of the vehicle. This
is called the Gross Vehicle
Weight Rating (GVWR). The
GVWR includes the weight
of the vehicle, all
occupants, fuel, and cargo.
The Certification/Tire label
may also show the
maximum weights for the
front and rear axles, called
the Gross Axle Weight
Rating (GAWR). To find out
the actual loads on the
front and rear axles, weigh
the vehicle at a weigh
station. Your dealer can
help with this. Be sure to
spread the load equally on
both sides of the
centerline.
Caution
Overloading the vehicle may
cause damage. Repairs
would not be covered by the
vehicle warranty. Do not
overload the vehicle.
{Warning
Things inside the vehicle
can strike and injure
people in a sudden stop
or turn, or in a crash.
.Put things in the cargo
area of the vehicle. In
the cargo area, put
them as far forward as
possible. Try to spread
the weight evenly.
.Never stack heavier
things, like suitcases,
inside the vehicle so
that some of them are
above the tops of the
seats.

New Vehicle Break-In
Caution
The vehicle does not need
an elaborate break-in. But it
will perform better in the
long run if you follow these
guidelines:
.Do not drive at any one
constant speed, fast or
slow, for the first 800 km
(500 mi). Do not make(Continued)
Caution (Continued)
full-throttle starts. Avoid
downshifting to brake or
slow the vehicle.
.Avoid making hard stops
for the first 300 km
(200 mi) or so. During this
time the new brake linings
are not yet broken in. Hard
stops with new linings can
mean premature wear and
earlier replacement.
Follow this breaking-in
guideline every time you
get new brake linings.
.Do not tow a trailer during
break-in. See Trailer
Towing0318 for the
trailer towing capabilities
of the vehicle and more
information.
Following break-in, engine
speed and load can be
gradually increased.
On new vehicles, the various
mechanical and electrical
systems experience a “break-in”
period during the
first 6 400 km (4,000 mi) of
routine driving. As the vehicle
is driven, the mechanical
systems adjust to provide
optimal fuel economy and
transmission shift
performance.
Electrical systems will adapt
and calibrate during the
break-in period. A one-time
occurrence of clicks and
similar vehicle noises is normal
during this process.
Normal driving charges the
vehicle’s battery to achieve
the best operation of the
vehicle, including fuel economy
and the Stop/Start System.
See Stop/Start System 0249.

turn the engine off.
If the vehicle is in P (Park), the
ignition will turn off, and
Retained Accessory
Power (RAP) will remain active.
See Retained Accessory
Power (RAP) 0253.
If the vehicle is in R (Reverse),
D (Drive) or M (Manual Mode),
the vehicle will shift to
P (Park), the ignition will turn
off, and RAP will remain active.
If the vehicle is in N (Neutral),
the ignition will return to
accessory mode and display
the message SHIFT TO PARK
in the Driver Information
Center (DIC).
When the vehicle is shifted
into P (Park), the ignition will
turn off.
{Warning
Turning off the vehicle while
moving may cause loss of
power assist in the brake
and steering systems and
disable the airbags. While
driving, only shut the vehicle
off in an emergency.
If the vehicle must be shut off
in an emergency: 1. Brake using a firm and steady pressure. Do not
pump the brakes
repeatedly. This may
deplete power assist,
requiring increased brake
pedal force.
2. Shift the vehicle to N (Neutral). This can be
done while the vehicle is
moving. After shifting to
N (Neutral), firmly apply the
brakes and steer the
vehicle to a safe location.
3. Come to a complete stop and shift to P (Park).

Caution
If you add electrical parts or
accessories, you could
change the way the engine
operates. Any resulting
damage would not be
covered by the vehicle
warranty. See Add-On
Electrical Equipment0325.
To start the vehicle: 1. With the Keyless Access system, the remote key
must be in the vehicle.
Press ENGINE START/
STOP with the brake pedal
applied. When the engine
begins cranking, let go of
the button. The idle speed
will go down as the engine
warms up. Do not race the
engine immediately after
starting it.
If the remote key is not in
the vehicle, if there is
interference, or if the
remote key battery is low,
a Driver Information Center (DIC) message will
display. See Remote Key
Operation
09.
Caution
Cranking the engine for long
periods of time, by pressing
ENGINE START/STOP
immediately after cranking
has ended, can overheat and
damage the cranking motor,
and drain the battery. Wait
at least 15 seconds between
each try, to let the cranking
motor cool down.
2. If the engine does not start after five to 10 seconds,
especially in very cold
weather (below −18 °C or
0 °F), it could be flooded
with too much gasoline.
Try pushing the
accelerator pedal all the
way to the floor and hold it
there, then press ENGINE
START/STOP for up to a
maximum of 15 seconds.
Wait at least 15 seconds
between each try, to allow the cranking motor to cool
down. When the engine
starts, let go of the button
and the accelerator. If the
vehicle starts briefly but
then stops again, do the
same thing. This clears the
extra gasoline from the
engine. Do not race the
engine immediately after
starting it. Operate the
engine and transmission
gently until the oil warms
up and lubricates all
moving parts.
Stop/Start System
The Stop/Start system will
shut off the engine to help
conserve fuel. It has
components designed for the
