ACC may occasionally provide an alert
and/or braking that is considered
unnecessary. It could respond to
vehicles in different lanes, signs,
guardrails, and other stationary
objects when entering or exiting a
curve. This is normal operation. The
vehicle does not need service.
Other Vehicle Lane Changes
ACC will not detect a vehicle ahead
until it is completely in the lane. The
brakes may need to be manually
applied.
Objects Not Directly in Front of Your
Vehicle
The detection of objects in front of
the vehicle may not be possible if:
.The vehicle or object ahead is not
within your lane.
.The vehicle ahead is shifted, not
centered, or is shifted to one side of
the lane.
Driving in Narrow Lanes

DRIVING AND OPERATING 255
{Warning
The Park Assist System is no
substitute for careful and attentive
driving. The Park Assist system
does not detect children,
pedestrians, bicyclists, animals,
or objects located below the
bumper or that are too close or too
far from the vehicle. It is not
available at speeds greater than
9 km/h (6 mph). To prevent injury,
death, or vehicle damage, even with
Park Assist, always check the area
around the vehicle and check all
mirrors before moving forward or
backing.
How the System Works
The vehicle may have a Park
Assist amphitheatre-like display on
the cluster with bars that represent
the estimated location of a detected
object and the vehicle’s distance from
the object. As a detected object
becomes closer, more bars light up
and change color from yellow to
amber to red. When an object is first detected in the
rear, one beep will be heard from the
rear, or the driver's seat will pulse two
times, if equipped with Safety Alert
Seat. When an object is very close,
five beeps will sound from the front or
rear (depending on the object's
location), or the driver's seat will pulse
five times. Beeps for front are higher
pitched than the rear.
Turning the System On and Off
The Park Assist System can be turned
on or off using the infotainment
system. See
Vehicle Personalization
0 121.
The
Xbutton is used to turn on or
off the Park Assist, which also turns
on or off the Backing Warning and
Reverse Automatic Braking (RAB) at the same time. When the system is
turned off, a system off message is
shown on the display. This message
disappears after a short period
of time.
Turn off Park Assist when towing a
trailer to prevent unwanted beeps and
when a bike rack is attached to ensure
proper operation.
When the System Does Not Seem to
Work Properly
If a service message displays, check
the following conditions:
.The sensors may not be clean. Keep
the vehicle's front and rear bumpers
free of mud, dirt, snow, ice, and
slush. For cleaning instructions, see
Exterior Care
0357.
.The Park Assist sensors may be
covered by frost or ice. Frost or ice
can form around and behind the
sensors and may not always be
seen; this can occur after washing
the vehicle in cold weather. The
message may not clear until the
frost or ice has melted.

vehicle until the parking brake or
brake is applied, or the vehicle is
shifted into P (Park). To start driving
away, press the brakes and shift into
D (Drive).
Certain vehicle conditions and driver
interferences may also cancel
automatic parking:
.The driver manually steers the
vehicle.
.The maximum allowed speed is
exceeded.
.There is a failure with the APA
system.
.Electronic stability control or
antilock brakes are activated.
.The parking brake is applied.
.Driver unbuckles the seat belt and
opens the door.
System Limitations
Automatic Parking Assist has 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)
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
backing speeds, there may not be
enough time for the short, sharp
application of the vehicle brake

two beeps from the rear, or if
equipped, two pulses from both sides
of the driver seat. When a pedestrian
is detected close to the vehicle, the
symbol flashes red on the
infotainment display, along with seven
beeps from the rear, or if equipped,
seven pulses from both sides of the
driver seat.
{Warning
Rear Pedestrian Alert does not
automatically brake the vehicle.
It also does not provide an alert
unless it detects a pedestrian, and it
may not detect all pedestrians if:
.The pedestrian is not directly
behind the vehicle, fully visible
to the Rear Vision Camera (RVC),
or standing upright.
.The pedestrian is part of a group.
.The pedestrian is a child.
.Visibility is poor, including
nighttime conditions, fog, rain,
or snow.
.The RVC is blocked by dirt, snow,
or ice.(Continued)
Warning (Continued)
.The RVC, taillamps, or back-up
lamps are not cleaned or in
proper working condition.
.The vehicle is not in R (Reverse).
To help avoid death or injury,
always check for pedestrians
around the vehicle before backing
up. Be ready to take action and
apply the brakes. See Defensive
Driving 0205. Keep the RVC,
taillamps, and back-up lamps clean
and in good repair.
Rear Pedestrian Alert can be set to Off
or Alert. See “Rear Pedestrian
Detection ”in “Collision/Detection
Systems” underVehicle Personalization
0 121. If equipped, alerts can be set to
beeps or seat pulses. See “Alert Type”
in “Collision/Detection Systems” under
Vehicle Personalization 0121.
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 attached to the vehicle.
Turning the Features On or Off
RCTA can be turned on or off using
the infotainment system. See
“Collision/Detection Systems” under
Vehicle Personalization 0121.

264 DRIVING AND OPERATING
Warning (Continued)
.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 (Continued)
Warning (Continued)
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 personalization. See
“Collision/
Detection Systems” underVehicle
Personalization 0121.
{Warning
Using AEB or IBA while towing a
trailer could cause you to lose
control of the vehicle and crash.
Turn the system to Alert, or if the
vehicle has ACC to Off, when
towing a trailer.
A system unavailable message may
display if:
.The front of the vehicle or
windshield is not clean.
.Heavy rain or snow is interfering
with object detection.
.There is a problem with the
StabiliTrak/Electronic Stability
Control (ESC) system.
The AEB system does not need
service.

266 DRIVING AND OPERATING
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.
If this happens, Automatic Braking
may engage the Electric Parking Brake
(EPB) to hold the vehicle at a stop.
Release the EPB. A firm press of the
accelerator pedal will also release
Automatic Braking and the EPB.
{Warning
FPB may alert or automatically
brake the vehicle suddenly in
situations where it is unexpected
and undesired. It could falsely alert
or brake for objects similar in shape
or size to pedestrians, including
shadows. This is normal operation
and the vehicle does not need
service. To override Automatic
Braking, firmly press the accelerator
pedal, if it is safe to do so.
Automatic Braking can be disabled
through vehicle personalization. See
“Front Pedestrian Detection
”in
“Collision/Detection Systems” under
Vehicle Personalization 0121.
{Warning
Using the Front Pedestrian Braking
system while towing a trailer could
cause you to lose control of the
vehicle and crash. Turn the system
to Alert or Off when towing a
trailer.
Cleaning the System
If FPB does not seem to operate
properly, cleaning the outside of the
windshield in front of the rearview
mirror may correct the issue.
Side Blind Zone
Alert (SBZA)
If equipped, the SBZA system is a
lane-changing aid that assists drivers
with avoiding crashes that occur with
moving vehicles in the side blind
zone, or blind spot areas. When the
vehicle is in a forward gear, the left or

Cadillac XT4 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
15440907) - 2022 - CRC - 1/4/22
268 DRIVING AND OPERATING
When the vehicle is started, both
outside mirror LCA displays will
briefly come on to indicate the system
is operating. When the vehicle is in a
forward gear, the left or right side
mirror display will light up if a moving
vehicle is detected in the next lane
over in that blind zone or rapidly
approaching that zone. If the turn
signal is activated in the same
direction as a detected vehicle, this
display will flash as an extra warning
not to change lanes.
LCA can be disabled through vehicle
personalization. When you disable
LCA, SBZA is also disabled. SeeVehicle
Personalization 0121. If LCA is
disabled by the driver, the LCA mirror
displays will not light up.
When the System Does Not
Seem to Work Properly
The LCA system requires some driving
for the system to calibrate to
maximum performance. This
calibration may occur more quickly if
the vehicle is driving on a straight
highway road with traffic and roadside
objects (e.g., guardrails, barriers). LCA displays may not come on when
passing a vehicle quickly, for a
stopped vehicle, or when towing a
trailer. 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. LCA may alert to objects
attached to the vehicle, such as a
trailer, bicycle, or object extending out
to either side of the vehicle. Attached
objects may also interfere with the
detection of vehicles. This is normal
system operation; the vehicle does not
need service.
LCA may not always alert the driver to
vehicles in the next lane over,
especially in wet conditions or when
driving on sharp curves. The system
does not need to be serviced. The
system may light up due to guardrails,
signs, trees, shrubs, and other
non-moving objects. This is normal
system operation; the vehicle does not
need service.
LCA may not operate when the LCA
sensors in the left or right corners of
the rear bumper are covered withmud, dirt, snow, ice, or slush, or in
heavy rainstorms. For cleaning
instructions, see "Washing the
Vehicle" under
Exterior Care0357.
If the DIC still displays the system
unavailable message after cleaning
both sides of the vehicle toward the
rear corners of the vehicle, see your
dealer.
If the LCA displays do not light up
when moving vehicles are in the side
blind zone or are rapidly approaching
this zone and the system is clean, the
system may need service. Take the
vehicle to your dealer.
Radio Frequency Information
See Radio Frequency Statement 0393.
Lane Keep Assist (LKA)
If equipped, LKA may help avoid
crashes due to unintentional lane
departures. This system uses a camera
to detect lane markings. The LKA may
be ready to assist at speeds between
50 km/h (31 mph) and 180 km/h
(112 mph). LKA may assist by gently
turning the steering wheel if the
vehicle approaches a detected lane

Cadillac XT4 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
15440907) - 2022 - CRC - 1/4/22
DRIVING AND OPERATING 269
marking. It may also provide a Lane
Departure Warning (LDW) alert if the
vehicle crosses a detected lane
marking. This system is not intended
to keep the vehicle centered in the
lane. LKA will not assist and alert if
the turn signal is active in the
direction of lane departure, or if it
detects that you are accelerating,
braking or actively steering. LKA can
be overridden by turning the steering
wheel. If the system detects you are
steering intentionally across a lane
marker, the LDW will not be given. Do
not expect the LDW to occur when
you are intentionally crossing a lane
marker.
{Warning
The LKA system does not
continuously steer the vehicle.
It may not keep the vehicle in the
lane or give a Lane Departure
Warning (LDW) alert, even if a lane
marking is detected.(Continued)
Warning (Continued)
The LKA and LDW systems
may not:
.Provide an alert or enough
steering assist to avoid a lane
departure or crash.
.Detect lane markings under poor
weather or visibility conditions.
This can occur if the windshield
or headlamps are blocked by dirt,
snow, or ice; if they are not in
proper condition; or if the sun
shines directly into the camera.
.Detect road edges.
.Detect lanes on winding or hilly
roads.
If LKA only detects lane markings
on one side of the road, it will only
assist or provide an LDW alert
when approaching the lane on the
side where it has detected a lane
marking. Even with LKA and LDW,
you must steer the vehicle. Always
keep your attention on the road and
maintain proper vehicle position (Continued)
Warning (Continued)
within the lane, or vehicle damage,
injury, or death could occur. Always
keep the windshield, headlamps,
and camera sensors clean and in
good repair. Do not use LKA in bad
weather conditions or on roads with
unclear lane markings, such as
construction zones.
{Warning
Using LKA on slippery roads could
cause loss of control of the vehicle
and a crash. Turn the system off.
{Warning
LKA will not alert the driver if a
towed trailer crosses into an
adjacent lane of travel. Serious
injury or property damage may
occur if the trailer moves into
another lane. Always monitor the
trailer position while towing to
make sure it is within the same
lane as the tow vehicle.

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.
