{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
display the list of available
options and select “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.
Front Pedestrian
Braking (FPB) System
If equipped, the FPB system
may help avoid or reduce the
harm caused by front-end

Driving and Operating 347
crashes with nearby
pedestrians when driving in a
forward gear. FPB displays an
amber indicator,
~, when a
nearby pedestrian is detected
ahead. When approaching a
detected pedestrian 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.
See Automatic Emergency
Braking (AEB) 0345.
The FPB system can detect
and alert to pedestrians 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 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:
.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.
(Continued)
Warning (Continued)
Be ready to take action and
apply the brakes. For more
information, see Defensive
Driving0235. Keep the
windshield, headlamps, and
FPB sensor clean and in
good repair.
FPB can be set to Off, Alert,
or Alert & Brake through
vehicle personalization. To
view available settings for this
feature, touch the Settings
icon on the infotainment home
page. Select “Vehicle”to

348 Driving and Operating
FPB alerts and automatic
braking will not occur unless
the FPB system detects a
pedestrian. When a nearby
pedestrian is detected in front
of the vehicle, 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.
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.

{Warning
Using the FPB 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 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.
{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.

350 Driving and Operating
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 outside 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 Outside
Mirror DisplayRight Outside
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 outside 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. When
you disable LCA, Side Blind
Zone Alert is also disabled. To
view available settings from
the infotainment screen, touch
Settings > 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 driving on a straight

Cadillac CT4 Owner Manual (GMNA-Localizing-U.S./Canada-16500442) -

Driving and Operating 351
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 dueto 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 Care
0
455. 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.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. LKA may
be ready to assist at speeds
between 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
unintentionally crosses a
detected lane marking. This
system is not intended to keep
the vehicle centered in the
lane. LKA will not assist or
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

Driving and Operating 353
Warning (Continued)
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 unintended lane
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
Aon 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,
Ais white,
if equipped, indicating that the
system is not ready to assist.
Ais green if LKA is ready to
assist. LKA may assist by
gently turning the steering
wheel if the vehicle
approaches a detected lane
marking.
Ais amber when
assisting. It may also provide a
Lane Departure Warning
(LDW) alert by flashing
A
amber 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. 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.Fuel
