210 Driving and Operating
When engaged and not steering the vehicle,
the steering wheel light bar flashes blue,
and the Super Cruise light
Zwill display
blue. The driver is in control of steering and
Super Cruise is not steering the vehicle.
When the vehicle is positioned in the center
of the lane, the steering wheel light bar
and the Super Cruise light
Zwill display
green, indicating Super Cruise is steering the
vehicle.
When Super Cruise controls the steering,
traffic and other conditions and laws permit,
and it is safe to do so, your hands can be
taken off the steering wheel.
Always pay attention to the road and the
operation of the vehicle. Always monitor
and be attentive of surrounding traffic,
including vehicles that may cross the road in
front of your vehicle.
Super Cruise steering can be overridden with
manual steering at any time. When Super
Cruise is engaged, always be prepared to
take immediate action —including steering,
accelerating, and braking quickly,
if necessary.
Super Cruise, when engaged, will enable
Forward Collision System to Alert and Brake. Steering Manually and Changing Lanes
The vehicle can always be manually steered,
even with Super Cruise engaged; for
example, when changing lanes.
When the steering wheel is moved
manually, the steering wheel light bar
pulses blue and the Super Cruise lightZ
on the instrument cluster turns blue to
indicate that Super Cruise is not steering the
vehicle.
When ready to allow Super Cruise to
resume steering again, position the vehicle
in the center of the lane, hold the steering
wheel until the steering wheel light bar
turns green, and then release the steering
wheel when it is safe to do so.
{Warning
To help prevent crashes before making a
lane change:
.Always check mirrors.
.Glance over your shoulder.
.Use the turn signals.
Super Cruise Lane Change

Rear Cross Traffic Braking (RCTB)
If equipped, RCTB displays a red warning
triangle with a left or right pointing arrow
on the infotainment screen to warn of
traffic coming from the left or right. The
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,
three beeps sounds from the left or right,
depending on the direction of the detected
vehicle. RCTB will bring the vehicle to a full
stop if a collision is imminent.
Driving With a Trailer
Use caution while backing up when towing
a trailer. RCTA and RCTB are automatically
disabled when a trailer is attached to the
vehicle.
Turning the Feature On or Off
To view available settings from the
infotainment screen, touch Settings >
Vehicle > Collision/Detection Systems.
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), AutomaticEmergency 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.
FCA can detect vehicles to distances of
approximately 110 m (360 ft) and operates at
all speeds.
{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, or other
objects. Be ready to take action and
apply the brakes. SeeDefensive Driving
0 164.
FCA can be disabled. To view available
settings from the infotainment screen, touch
Settings > Vehicle > 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

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

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)

front, or both sides of the Safety Alert Seat
will pulse five times. When this Collision
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.

Without Head-Up Display
Automatic Braking
If I-AEB detects it is about to crash into an
intersecting vehicle, and the brakes have not
been applied, I-AEB may automatically brake
moderately or hard. This can help to avoid
some crashes or lessen impact by reducing the speed of the vehicle. Always wear a seat
belt and check that all passengers are
properly restrained. I-AEB can automatically
brake between 15 km/h (9 mph) and
80 km/h (50 mph). Automatic braking levels
may be reduced under certain conditions,
such as higher speeds.
I-AEB may slow the vehicle to a complete
stop to try to avoid a potential crash. If this
happens, I-AEB may engage the Electric
Parking Brake (EPB) to hold the vehicle at a
stop. Release the EPB or firmly press the
accelerator pedal to continue driving.
I-AEB may also apply the brakes
automatically when there is an intersecting
vehicle at risk of collision and the system
determines that the driver is not braking
with sufficient force.
Minor brake pedal pulsations or pedal
movement during this time is normal and
the brake pedal should continue to be
applied as needed.
{Warning
I-AEB may automatically brake or increase
vehicle braking in situations when it may
not be necessary or desired. Your vehicle

Warning (Continued)
could block the flow of traffic. I-AEB may
respond to stationary or parked vehicles,
signs, and other non-moving objects. To
override AEB, firmly press the accelerator
pedal, if it is safe to do so.
{Warning
Using I-AEB 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 I-AEB does not seem to operate properly,
cleaning the outside of the windshield in
front of the rearview mirror may correct the
issue.
Front Pedestrian Braking (FPB)
System
If equipped, the FPB system may help avoid
or reduce the harm caused by front-end
crashes with nearby pedestrians or bicyclists
when driving in a forward gear. FPB displays
an amber indicator,
~, when a nearby

Cadillac XT4 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
17180837) - 2024 - CRC - 2/28/23
Driving and Operating 239
pedestrian or bicyclist is detected ahead.
When approaching a detected pedestrian or
bicyclist too quickly, FPB provides a red
flashing alert on the windshield and rapidly
beeps or pulses the driver seat. FPB can
provide a boost to braking or automatically
brake the vehicle. This system includes
Intelligent Brake Assist (IBA), and the
Automatic Emergency Braking (AEB) system
may also respond to pedestrians or
bicyclists. SeeAutomatic Emergency Braking
(AEB) 0235.
The FPB system can detect and alert to
pedestrians or bicyclists in a forward gear at
speeds between 8 km/h (5 mph) and
80 km/h (50 mph). During daytime driving,
the system detects pedestrians or bicyclists
up to a distance of approximately 40 m
(131 ft). During nighttime driving, system
performance is very limited.
{Warning
FPB does not provide an alert or
automatically brake the vehicle, unless it
detects a pedestrian. FPB may not detect
pedestrians, including children: (Continued)
Warning (Continued)
.When the pedestrian is not directly
ahead, fully visible, or standing
upright, or when part of a group.
.Due to poor visibility, including
nighttime conditions, fog, rain,
or snow.
.If the FPB sensor is blocked by dirt,
snow, or ice.
.If the headlamps or windshield are not
cleaned or in proper condition.
Be ready to take action and apply the
brakes. For more information, see
Defensive Driving 0164. Keep the
windshield, headlamps, and FPB sensor
clean and in good repair.
FPB can be set to Off, Alert, or Alert and
Brake through vehicle settings. To view
available settings from the infotainment
screen, touch Settings > Vehicle > Collision/
Detection Systems.
Detecting the Pedestrian Ahead
FPB alerts and automatic braking will not
occur unless the FPB system detects a
pedestrian or bicyclist. When a pedestrian or
bicyclist that may enter the vehicle’s
forward path is detected, the pedestrian
ahead indicator will display amber.
Front Pedestrian Alert
With Head-Up Display

17180837) - 2024 - CRC - 2/28/23
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.

Turning the Feature On or Off
Bicyclist Detection can be turned on or off
through vehicle settings. To view available
settings from the infotainment screen, touch
Settings > Vehicle > Collision/Detection
Systems.
Blind Zone Steering Assist (BZSA)
If equipped, the Blind Zone Steering Assist
(BZSA) system can detect a potential crash
with a moving vehicle in the lane you are
entering. It provides a brief, urgent turn of
the steering wheel to alert you to take
action to avoid a collision.
BZSA works with the Lane Keep Assist (LKA).
BZSA operates when the vehicle is in a
forward gear, and only when LKA is enabled
and able to assist. SeeLane Keep Assist
(LKA) 0245.
BZSA will provide a steering correction when
your vehicle is about to leave the current
lane of travel, with the possibility of a
collision with a vehicle in the adjacent lane.
This steering correction happens closer to
the center of the lane and has a stronger
steering correction than LKA. Unlike LKA, the
steering correction with BSZA will happen
even if your turn signal is on in the
direction of lane departure. In addition to the BZSA steering
intervention, the
Awill turn amber, six
beeps or six seat pulses will occur,
if equipped with Safety Alert Seat, and
8or|will flash on the outside
rear view mirror.
{Warning
Do not rely on Blind Zone Steering Assist
(BZSA) to prevent crashes. This system
does not replace the need to pay
attention and drive safely. Failure to use
proper care when driving may result in
vehicle damage, injury, or death.
.BZSA performance may be affected by
weather and road conditions.
.BZSA does not provide steering
assistance to avoid a vehicle that is in,
or has entered, your lane of travel.
.BZSA will not prevent a towed trailer
from crossing into the adjacent lane.
Always monitor the trailer position
while towing to ensure it is in the
same lane as your vehicle. BZSA is
only designed to detect when your
vehicle unintentionally crosses
detected lane lines.
Traffic Sign Assistant
If equipped, Traffic Sign Assistant recognizes
designated traffic signs via the front camera
located behind the windshield in front of the
interior rear view mirror, and displays the
detected speed limit in the Driver
Information Center (DIC). Additionally, speed
limit information from the navigation
system map database may be used.
Caution
The system is intended to assist the
driver within a defined speed range to
discern certain traffic signs. Always pay
attention to posted speed limit signs.
Do not ignore traffic signs which are not
displayed by the system.
The system does not discern any signs
other than the conventional traffic signs
that might give or end a speed limit.
It may not detect some electronic speed
signs.
