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.

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.

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.

Lane Change Alert (LCA)
If equipped, the LCA system is a
lane-changing aid that assists drivers with
avoiding lane change crashes that occur with
moving vehicles in the side blind zone (or
spot) areas or with vehicles rapidly
approaching these areas from behind. The
LCA warning display will light up in the
corresponding outside mirror and will flash
if the turn signal is on.
Side Blind Zone Alert (SBZA) is included as
part of the LCA system.
{Warning
LCA does not alert the driver to vehicles
outside of the system detection zones,
pedestrians, bicyclists, or animals. It may
not provide alerts when changing lanes
under all driving conditions. Failure to use
proper care when changing lanes may
result in injury, death, or vehicle damage.
Before making a lane change, always
check mirrors, glance over your shoulder,
and use the turn signals.LCA Detection Zones
1. SBZA Detection Zone
2. LCA Detection Zone
The LCA sensor covers a zone of
approximately one lane over from both
sides of the vehicle, or 3.5 m (11 ft). The
height of the zone is approximately between
0.5 m (1.5 ft) and 2 m (6 ft) off the ground.
The Side Blind Zone Alert (SBZA) warning
area starts at approximately the middle of
the vehicle and goes back 5 m (16 ft). Drivers
are also warned of vehicles rapidly
approaching from up to 70 m (230 ft) behind
the vehicle.
How the System Works
The LCA symbol lights up in the side mirrors
when the system detects a moving vehicle
in the next lane over that is in the side blind zone or rapidly approaching that zone
from behind. A lit LCA symbol indicates it
may be unsafe to change lanes. Before
making a lane change, check the LCA
display, check mirrors, glance over your
shoulder, and use the turn signals.
Left Side Mirror
DisplayRight Side Mirror Display
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.To view available settings

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.

Limitations
Traffic sign memory may not operate
correctly if:
.The area of the windshield, where the
front camera is located, is not clean or is
affected by foreign objects, e.g. stickers,
window tinting, etc.
.Traffic signs are completely or partially
covered, are too low or high or difficult to
discern.
.Traffic signs are incorrectly mounted or
are damaged.
.Traffic signs do not comply with the
approved traffic sign standards.
.The speed limit is displayed by certain
types of electronic speed signs.
.There are adverse environmental
conditions, e.g. heavy rain, snow, direct
sunlight or shadows.
.The headlights are dirty or not correctly
aligned when driving at night.
.The navigation map data is out of date.
.The navigation map is unavailable.
Lane Keep Assist (LKA)
If equipped, LKA may help avoid crashes due
to unintentional lane departures. This
system uses a camera to detect lanemarkings. The LKA system can be ready to
assist at speeds between approximately
60 km/h (37 mph) and 180 km/h (112 mph).
On some vehicles, the system will instead
operate above 50 km/h (31 mph). LKA may
assist by gently turning the steering wheel
if the vehicle approaches a detected lane
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 may 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
within the lane, or vehicle damage,
injury, or death could occur. Always keep
the windshield, headlamps, and camera (Continued)

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.
How the System Works
LKA uses a camera sensor installed on the
windshield ahead of the rearview mirror to
detect lane markings. It may provide brief
steering assist if it detects an unintendedlane departure. It may further provide an
audible alert or the driver seat may pulse
indicating that a lane marking has been
crossed. The system does not provide a Lane
Departure Warning (LDW) when
intentionally steering across a lane marker.
To turn LKA on and off, press
non the
center stack. If equipped, the indicator light
on the button comes on when LKA is on and
turns off when LKA is disabled. In some
vehicles a long press of over three seconds
is required to turn LKA off.
When on,

nis amber when
assisting. It may also provide a Lane
Departure Warning (LDW) alert by flashing
namber if the vehicle crosses a detected
lane marking. Additionally, there may be
three beeps, or the driver seat may pulse
three times, on the right or left, depending
on the lane departure direction. Take Steering
The LKA system does not continuously steer
the vehicle. If LKA does not detect active
driver steering, an alert and chime may be
provided. Steer the vehicle to dismiss. LKA
may become temporarily unavailable after
repeated take steering alerts.
When the System Does Not Seem to
Work Properly
The system performance may be
affected by:
.Close vehicles ahead.
.Sudden lighting changes, such as when
driving through tunnels.
.Banked roads.
.Roads with poor lane markings, such as
two-lane roads.
If the LKA system is not functioning
properly when lane markings are clearly
visible, cleaning the windshield may help.
A camera blocked message may display if
the camera is blocked. Some driver
assistance systems may have reduced
performance or not work at all. An LKA or
LDW unavailable message may display if the
systems are temporarily unavailable. This
message could be due to a blocked camera.
