APA selects the nearest
empty parking spot behind the
vehicle, but under some
conditions may select a space
that is further back. Slow
down and bring the vehicle to
a complete stop to begin.
Follow the displayed
instructions. When instructed
to drive in reverse, shift to
R (Reverse) while holding the
brakes. The steering wheel will
vibrate briefly as a reminder to
remove hands from the
steering wheel. After the
vibration stops, check your
surroundings and release the
brakes to begin automatic
parking. As the vehicle
automatically steers, and
brakes into the parking spot,
check surroundings and
continue to apply acceleration
if necessary and shift gears as
needed. Be prepared to stop
to avoid vehicles, pedestrians,
or objects.A progress arrow displays the
status of the parking
maneuver. Once automatic
parking is finished and the
vehicle has come to a full stop,
APA will beep and display a
message indicating parking is
complete. Shift the vehicle to
P (Park) and apply the parking
brake

certain limitations. The system
cannot:
.Continue to operate if the
maneuver speed exceeds
5 km/h (3 mph).
.Detect whether a parking
space is legal or restricted.
.Detect pavement markings
or lines.
.Park the vehicle closely lined
up with the vehicle next to it,
particularly if the spot is
approached at an angle or if
the parking space is angled.
.Park exactly centered in a
very large spot.
.Always detect short curbs.
.Operate while towing any
trailer.
.Function the vehicle is raised
or lowered by air
suspension,if equipped.
When the System Does Not
Seem to Work Properly
If the vehicle does not reverse
into the expected parking
space, the system could be
maneuvering the vehicle into a
previously detected space.
Reverse Automatic
Braking (RAB)
Backing Warning and
Reverse Automatic
Braking (RAB)
If equipped, vehicles with
Adaptive Cruise Control (ACC)
have the Backing Warning
System and Reverse
Automatic Braking (RAB)
system. When in R (Reverse),
Backing Warning alerts of rear
objects at vehicle speeds
greater than 8 km/h (5 mph), and RAB may automatically
brake hard at speeds between
1–32 km/h (0.5–20 mph).
The Backing Warning System
will beep once from the rear
when an object is first
detected, or pulse twice on
both sides of the Safety Alert
Seat. When the system
detects a potential crash,
beeps will be heard from the
rear, or five pulses will be felt
on both sides of the Safety
Alert Seat. There may also be
a brief, sharp application of
the brakes.
{Warning
The Backing Warning
System only operates at
speeds greater than 8 km/h
(5 mph). It does not detect
children, pedestrians,
bicyclists, animals, or objects
below the bumper or that
are too close or too far from
the vehicle. In some
situations, such as at higher

Warning (Continued)
backing speeds, there may
not be enough time for the
short, sharp application of
the vehicle brake system to
occur. To prevent injury,
death, or vehicle damage,
even with the Backing
Warning System, always
check the area around the
vehicle and check all mirrors
before backing.
When the vehicle is in
R (Reverse), if the system
detects the vehicle is backing
too fast to avoid a crash with
a detected object behind your
vehicle in your path, it may
automatically brake hard to a
stop to help avoid or reduce
the harm caused by a backing
crash.
{Warning
RAB may not avoid many
types of backing crashes. Do
not wait for the automatic
braking to apply. This
system is not designed to
replace driver braking and
only works in R (Reverse)
when an object is detected
directly behind the vehicle.
It may not brake or stop in
time to avoid a crash. It will
not brake for objects when
the vehicle is moving at very
low speeds. It does not
detect children, pedestrians,
bicyclists, animals, or objects
below the bumper or that
are too close or too far from
the vehicle. To prevent
injury, death, or vehicle
damage, even with RAB,
always check the area
around the vehicle before
and while backing. Pressing the brake pedal after
the vehicle comes to a stop
will release RAB. If the brake
pedal is not pressed soon
after the stop, the Electric
Parking Brake (EPB) may be
set. When it is safe, press the
accelerator pedal firmly at any
time to override RAB.
{Warning
There may be instances
where unexpected or
undesired automatic braking
occurs. If this happens,
either press the brake pedal
or firmly press the
accelerator pedal to release
the brakes from the RAB
system. Before releasing the
brakes, check the RVC and
check the area around the
vehicle to make sure it is
safe to proceed.

Rear Cross Traffic
Alert (RCTA) System
If equipped, Rear Cross Traffic
Alert (RCTA) displays a red
warning triangle with a left or
right pointing arrow on the infotainment display to warn
of traffic coming from the left
or right. This system detects
objects coming from up to
20 m (65 ft) from the left or
right side of the vehicle. When
an object is detected, either
three beeps sound from the
left or right or three Safety
Alert Seat pulses occur on the
left or right side, depending on
the direction of the detected
vehicle.
Driving With a Trailer
Use caution while backing up
when towing a trailer. The
RCTA feature is automatically
disabled when a trailer is

Assistance Systems
for Driving
If equipped, when driving the
vehicle in a forward gear,
Forward Collision Alert (FCA),
Lane Keep Assist (LKA), Side
Blind Zone Alert (SBZA), Lane
Change Alert (LCA), Automatic
Emergency Braking (AEB),
and/or the Front Pedestrian
Braking (FPB) System can help
to avoid a crash or reduce
crash damage.
Forward Collision
Alert (FCA) System
If equipped, the FCA system
may help to avoid or reduce
the harm caused by front-end
crashes. When approaching a
vehicle ahead too quickly, FCA
provides a red flashing alert
on the windshield and rapidly
beeps or pulses the driver
seat. FCA also lights an amber
visual alert if following another
vehicle much too closely.

Cadillac XT4 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
16412876) - 2023 - CRC - 3/25/22
298 Driving and Operating
FCA detects vehicles within a
distance of approximately
60 m (197 ft) and operates at
speeds above 8 km/h (5 mph).
If the vehicle has Adaptive
Cruise Control (ACC), it can
detect vehicles to distances of
approximately 110 m (360 ft)
and operates at all speeds.
See Adaptive Cruise Control
(Advanced)0273.
{Warning
FCA is a warning system and
does not apply the brakes.
When approaching a
slower-moving or stopped
vehicle ahead too rapidly,
or when following a vehicle
too closely, FCA may not
provide a warning with
enough time to help avoid a
crash. It also may not
provide any warning at all.
FCA does not warn of
pedestrians, animals, signs,
guardrails, bridges,
construction barrels,

FCA can be disabled. To view
available settings for this
feature, touch the Settings
icon on the infotainment home
page. Select “Vehicle”to
display the list of available
options and select “Collision/
Detection Systems”.
Detecting the Vehicle
Ahead
FCA warnings will not occur
unless the FCA system
detects a vehicle ahead. When
a vehicle is detected, the
vehicle ahead indicator will display green. Vehicles may
not be detected on curves,
highway exit ramps, or hills,
due to poor visibility; or if a
vehicle ahead is partially
blocked by pedestrians or
other objects. FCA will not
detect another vehicle ahead
until it is completely in the
driving lane.
{Warning
FCA does not provide a
warning to help avoid a
crash, unless it detects a
vehicle. FCA may not detect
a vehicle ahead if the FCA
sensor is blocked by dirt,
snow, or ice, or if the
windshield is damaged.
It may also not detect a
vehicle on winding or hilly
roads, or in conditions that
can limit visibility such as
fog, rain, or snow, or if the
headlamps or windshield are
not cleaned or in proper
condition. Keep the

Warning (Continued)
AEB may not:
.Detect a vehicle ahead on
winding or hilly roads.
.Detect all vehicles,
especially vehicles with a
trailer, tractors, muddy
vehicles, etc.
.Detect a vehicle when
weather limits visibility,
such as in fog, rain,
or snow.
.Detect a vehicle ahead if it
is partially blocked by
pedestrians or other
objects.
Complete attention is
always required while
driving, and you should be
ready to take action and
apply the brakes and/or
steer the vehicle to avoid
crashes. AEB may slow the vehicle to a
complete stop to try to avoid a
potential crash. If this
happens, AEB may engage the
Electric Parking Brake (EPB)
to hold the vehicle at a stop.
Release the EPB or firmly
press the accelerator pedal.
{Warning
AEB may automatically
brake the vehicle suddenly in
situations where it is
unexpected and undesired.
It could respond to a turning
vehicle ahead, guardrails,
signs, and other non-moving
objects. To override AEB,
firmly press the accelerator
pedal, if it is safe to do so.
Intelligent Brake
Assist (IBA)
IBA may activate when the
brake pedal is applied quickly
by providing a boost to
braking based on the speed of
approach and distance to a
vehicle ahead. Minor brake pedal pulsations
or pedal movement during this
time is normal and the brake
pedal should continue to be
applied as needed. IBA will
automatically disengage only
when the brake pedal is
released.
{Warning
IBA may increase vehicle
braking in situations when it
may not be necessary. You
could block the flow of
traffic. If this occurs, take
your foot off the brake pedal
and then apply the brakes as
needed.
AEB and IBA can be disabled
through vehicle settings. To
view available settings for this
feature, touch the Settings
icon on the infotainment home
page. Select “Vehicle”to

the FPB system detects a pedestrian. When a pedestrian
that may enter the vehicle’s
forward path is detected, the
pedestrian ahead indicator will
display amber.
Front Pedestrian Alert
With Head-Up Display
Without Head-Up Display
When the vehicle approaches
a pedestrian ahead too rapidly,
the red FPB alert display will
flash on the windshield. Eight
rapid high-pitched beeps will
sound from the front, or both
sides of the Safety Alert Seat will pulse five times. When this
Pedestrian Alert occurs, the
brake system may prepare for
driver braking to occur more
rapidly which can cause a
brief, mild deceleration.
Continue to apply the brake
pedal as needed. Cruise
control may be disengaged
when the Front Pedestrian
Alert occurs.
Automatic Braking
If FPB detects it is about to
crash into a pedestrian
directly ahead, and the brakes
have not been applied, FPB
may automatically brake
moderately or brake hard. This
can help to avoid some very
low speed pedestrian crashes
or reduce pedestrian injury.
FPB can automatically brake
to detected pedestrians
between 8 km/h (5 mph) and
80 km/h (50 mph). Automatic
braking levels may be reduced
under certain conditions, such
as higher speeds.

Driving
Characteristics and
Towing Tips
{Warning
You can lose control when
towing a trailer if the correct
equipment is not used or the
vehicle is not driven
properly. For example, if the
trailer is too heavy or the
trailer brakes are
inadequate for the load, the
vehicle may not stop as
expected. You and others
could be seriously injured.
The vehicle may also be
damaged, and the repairs
would not be covered by the
vehicle warranty. Pull a
trailer only if all the steps in
this section have been
followed. Ask your dealer for
advice and information
about towing a trailer with
the vehicle.
Driving with a Trailer
Trailering is different than just
driving the vehicle by itself.
Trailering means changes in
handling, acceleration, braking,
durability, and fuel economy.
Successful, safe trailering
takes correct equipment, and
it has to be used properly.
The following information has
many time-tested, important
trailering tips and safety rules.
Many of these are important
for your safety and that of
your passengers. Read this
section carefully before pulling
a trailer.
When towing a trailer:
.Become familiar with and
follow all state and local laws
that apply to trailer towing.
These requirements vary
from state to state.
.State laws may require the
use of extended side view
mirrors. If your visibility is
limited or restricted while
towing, install extended side
view mirrors, even if not
required.
.Do not tow a trailer during
the first 800 km (500 mi) of
vehicle use to prevent
damage to the engine, axle,
or other parts.
.GM recommends performing
an oil change to the vehicle
before heavy towing.
.Do not drive over 80 km/h
(50 mph) and do not make
starts at full throttle during
the first 800 km (500 mi) of
trailer towing.
.Vehicles can tow in D (Drive).
If the transmission
downshifts too often, a
lower gear may be selected
using Manual Mode. See
Manual Mode0262.

Cadillac XT4 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
16412876) - 2023 - CRC - 3/25/22
Driving and Operating 315
If equipped, the following
driver assistance features
should be turned off when
towing a trailer:
.Adaptive Cruise
Control (ACC)
.Super Cruise Control
.Park Assist
.Automatic Parking
Assist (APA)
.Reverse Automatic
Braking (RAB)
If equipped, the following
driver assistance features
should be turned to alert or
off when towing a trailer:
.Automatic Emergency
Braking (AEB)
.Intelligent Brake Assist (IBA)
.Front Pedestrian
Braking (FPB)
If equipped with Lane Change
Alert (LCA), the LCA detection
zones that extend back from
the side of the vehicle do not
move further back when a trailer is towed. Use caution
while changing lanes when
towing a trailer.
If equipped with Rear Cross
Traffic Alert (RCTA), use
caution while backing up when
towing a trailer, as the RCTA
detection zones that extend
out from the back of the
vehicle do not move further
back when a trailer is towed.
{Warning
To prevent serious injury or
death from carbon monoxide
(CO), when towing a trailer:
.Do not drive with the
liftgate, trunk/hatch,
or rear-most
window open.
.Fully open the air outlets
on or under the
instrument panel.
(Continued)
Warning (Continued)
.Adjust the climate control
system to a setting that
brings in only outside air.
See“Climate Control
Systems” in the Index.
For more information about
carbon monoxide, see
Engine Exhaust 0256.
Towing a trailer requires
experience. The combination
of the vehicle and trailer is
longer and not as responsive
as the vehicle itself. Become
familiar to the handling and
braking by driving on a level
road surface before driving on
public roads.
The trailer structure, the tires,
and the brakes must be all be
rated to carry the intended
cargo. Inadequate trailer
equipment can cause the
combination to operate in an
unexpected or unsafe manner.
Before driving, inspect all
trailer hitch parts and

Cadillac XT4 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
16412876) - 2023 - CRC - 3/25/22
316 Driving and Operating
attachments, safety chains,
electrical connectors, lamps,
tires, and mirrors. See Towing
Equipment0322. If the trailer
has electric brakes, start the
combination moving and then
manually apply the trailer
brake controller to check that
the trailer brakes work. During
the trip, occasionally check
that the cargo and trailer are
secure and that the lamps and
any trailer brakes are working.
Towing with a Stability
Control System
When towing, the stability
control system might be
heard. The system reacts to
vehicle movement caused by
the trailer, which mainly occurs
during cornering. This is
normal when towing heavier
trailers.
Following Distance
Stay at least twice as far
behind the vehicle ahead as
you would when driving without a trailer. This can help
to avoid heavy braking and
sudden turns.
Passing
More passing distance is
needed when towing a trailer.
The combination of the vehicle
and trailer will not accelerate
as quickly and is much longer
than the vehicle alone. It is
necessary to go much farther
beyond the passed vehicle
before returning to the lane.
Pass on level roadways. Avoid
passing on hills if possible.
Backing Up
Hold the bottom of the
steering wheel with one hand.
To move the trailer to the left,
move that hand to the left. To
move the trailer to the right,
move that hand to the right.
Always back up slowly and,
if possible, have someone
guide you.
Making Turns
Caution
Turn more slowly and make
wider arcs when towing a
trailer to prevent damage to
your vehicle. Making very
sharp turns could cause the
trailer to contact the vehicle.
Make wider turns than normal
when towing, so the trailer will
not go over soft shoulders,
over curbs, or strike road
signs, trees, or other objects.
Always signal turns well in
advance. Do not steer or brake
suddenly.
Driving on Grades
Reduce speed and shift to a
lower gear before starting
down a long or steep downhill
grade. If the transmission is
not shifted down, the brakes
may overheat and result in
reduced braking efficiency.
