Location Services
This setting enables or disables sharing of
vehicle location outside the vehicle for
certain purposes. Even if the Location
Services setting is disabled, vehicle location
information will continue to be shared for
emergency services and Super Cruise,
if equipped.
System Care
The camera on the steering column has a
lens cover that may become dirty over time
and affect camera performance. Clean the
lens cover with a soft cloth sprayed with
glass cleaner. Wipe the lens gently, then dry
it. Never use abrasive cloths/cleaners or
corrosive chemicals of any kind on the lens
cover.
Super Cruise uses the front radar, front
camera, and 360 degree cameras for its
operation. Clean surfaces are required for
Super Cruise operation. SeeAdaptive Cruise
Control (Advanced) 0196, “Surround Vision
Camera” underAdvanced Driver Assistance
Systems 0223, and Lane Keep Assist (LKA)
0 245 for care information.Caution
The Super Cruise system is a highly
sophisticated system and should only be
serviced by technicians with the proper
training, tools, and safety instructions,
which your dealer has. Without proper
training and tools the vehicle may
become damaged.

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
0 321.
.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.
If a service message displays and the above
conditions do not exist, take the vehicle to
your dealer for repairs.
If the Park Assist System does not activate
due to a temporary condition, a system off
message is shown on the display. This can
occur under the following conditions:
.The driver has disabled the system.
.An object is currently blocking the rear
sensors (for example, bike rack, tailgate,
trailer hitch, etc.). Once the object is
removed, Park Assist will return to normal
operation.
.The bumper is damaged. Take the vehicle
to your dealer for repairs.
.Other conditions, such as vibrations from
a jackhammer or the compression of air
brakes on a very large truck, are affecting
system performance.
Automatic Parking Assist (APA)
Automatic Parking Assist (APA) with
Braking
If equipped, under certain conditions APA
with Braking can use sensors based on sonar
technology along the vehicle’s front, rear
and sides to detect a parking spot, and
automatically park the vehicle with some
driver assistance. The vehicle will
automatically maneuver into a detected spot
moving at or near idle speed. It does this by
automatically steering and braking while the
driver is responsible for acceleration and
gear shifting as needed. The driver must
always be prepared to apply braking or

Following Distance Indicator
The following distance to a moving vehicle
ahead in your path is indicated in following
time in seconds on the Driver Information
Center (DIC). SeeDriver Information Center
(DIC) 0111. The minimum following time is
0.5 seconds away. If there is no vehicle
detected ahead, or the vehicle ahead is out
of sensor range, dashes will be displayed.
Unnecessary Alerts
FCA may provide unnecessary alerts for
turning vehicles, vehicles in other lanes,
objects that are not vehicles, or shadows.
These alerts are normal operation and the
vehicle does not need service.
Cleaning the System
If the FCA system does not seem to operate
properly, this may correct the issue:
.Clean the outside of the windshield in
front of the rearview mirror.
.Clean the entire front of the vehicle.
.Clean the headlamps.
Automatic Emergency
Braking (AEB)
If equipped, the AEB system may help avoid
or reduce the harm caused by front-end
crashes. AEB also includes Intelligent Brake
Assist (IBA). When the system detects a
vehicle in the path ahead that is traveling in
the same direction, and that you may crash
into, it can provide a boost to braking,
or automatically brake the vehicle. This can
help avoid or lessen the severity of crashes
when driving in a forward gear. Depending
on the situation, the vehicle may
automatically brake moderately or hard. This
Automatic Emergency Braking can only
occur if a vehicle is detected. Vehicle
detection is shown by the Forward Collision
Alert (FCA) vehicle ahead indicator being lit.
See Forward Collision Alert (FCA) System
0 233.
The system works when driving in a forward
gear between 8 km/h (5 mph) and 80 km/h
(50 mph), or on vehicles with Adaptive
Cruise Control (ACC), above 4 km/h (2 mph).
It can detect vehicles up to approximately
60 m (197 ft).
{Warning
AEB is an emergency crash preparation
feature and is not designed to avoid
crashes. Do not rely on AEB to brake the
vehicle. AEB will not brake outside of its
operating speed range and only responds
to detected vehicles.
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

Cadillac XT4 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
17180837) - 2024 - CRC - 2/28/23
236 Driving and Operating
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 from the
infotainment screen, touch Settings >
Vehicle > Collision/Detection Systems.
{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 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.
Intersection Automatic Emergency
Braking (I-AEB) System
If equipped, the I-AEB system may help
avoid or reduce the harm caused by
front-end crashes with crossing vehicles,
or when performing a left-hand turn.
The system works when driving in a forward
gear above 15 km/h (9 mph) and less than
80 km/h (50 mph). It can detect oncoming
vehicles up to approximately 60 m (197 ft).
{Warning
I-AEB is an emergency crash preparation
feature. Do not rely on I-AEB to brake or
avoid crashes. I-AEB will not brake outside
of its operating speed range and only
responds to detected intersecting
vehicles. I-AEB may not:
.detect a crossing or oncoming vehicle
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. (Continued)

240 Driving and Operating
Without Head-Up Display
When the vehicle approaches a pedestrian
or bicyclist 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 or bicyclist 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 or bicyclist crashes or
reduce pedestrian injury. FPB can automatically brake to detected pedestrians
or bicyclists or bicyclists 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 or bicyclists,
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 settings.To view available settings
from the infotainment screen, touch Settings
> Vehicle > Collision/Detection Systems >
Front Pedestrian Detection.
{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 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 right side mirror display will light
up if a moving vehicle is detected in that
blind zone. If the turn signal is activated and
a vehicle is also detected on the same side,
the display will flash as an extra warning
not to change lanes. Since this system is
part of the Lane Change Alert (LCA) system,
read the entire LCA section before using this
feature.

17180837) - 2024 - CRC - 2/28/23
242 Driving and Operating
> Vehicle > Collision/Detection Systems.
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 driven 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 or for a stopped
vehicle. LCA may alert to objects attached to
the vehicle, such as a 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 with mud, dirt, snow,
ice, or slush, or in heavy rainstorms. For
cleaning instructions, see "Washing the
Vehicle" under
Exterior Care0321. 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
rapidly approaching this zone and the
system is clean, the system may need
service. Take the vehicle to your dealer.
Driving with a Trailer
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.
Side Bicycle Detection
If equipped, the system may detect a
bicyclist approaching from the side or rear
of the vehicle. If this occurs, a chime will sound in the
direction of the detection, and the Safety
Alert Seat will pulse if enabled through
vehicle settings. To view available settings
from the infotainment screen, touch Settings
> Vehicle > Collision/Detection Systems.
Bicyclist Detection is available when the
vehicle is in D (Drive), P (Park), and for a
short time after the vehicle is turned off.
If the vehicle detects a bicyclist when it is
off, a DIC message may display and alert to
the direction of the detection. In some
cases, an Unavailable message may display.
This is normal and does not mean that the
system is broken.
Detection Zones
When the vehicle is in P (Park) or is turned
off, a bicyclist can be detected 11 m (36 ft)
behind the vehicle or 10 m (33 ft) to the
side of the vehicle.
When the vehicle is in D (Drive), a bicyclist
can be detected 3 m (10 ft) behind the
vehicle or to the side of the vehicle.

The LKA system does not need service. Clean
the outside of the windshield behind the
rearview mirror.
LKA assistance and/or LDW alerts may occur
due to tar marks, shadows, cracks in the
road, temporary or construction lane
markings, or other road imperfections. This
is normal system operation; the vehicle does
not need service. Turn LKA off if these
conditions continue.
