icon on the infotainment home
page. Select“Vehicle”to

options and select “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 pedestrians or
other objects. FCA will not
detect another vehicle ahead
until it is completely in the
driving lane.
{Warning
FCA does not provide a
warning to help avoid a
crash, unless it detects a
vehicle. FCA may not detect
a vehicle ahead if the FCA
sensor is blocked by dirt,
snow, or ice, or if the
windshield is damaged.
It may also not detect a
vehicle on winding or hilly
roads, or in conditions that
can limit visibility such as
fog, rain, or snow, or if the
headlamps or windshield are
not cleaned or in proper
condition. Keep the
windshield, headlamps, and
FCA sensors clean and in
good repair. Collision Alert
With Head-Up Display
Without Head-Up Display
When your vehicle approaches
another detected vehicle too
rapidly, the red FCA display
will flash on the windshield.
Also, eight rapid high-pitched
beeps will sound from the
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

346 Driving and Operating
{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
Cadillac CT4 Owner Manual (GMNA-Localizing-U.S./Canada-16500442) -
2023 - CRC - 5/10/22
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
display the list of available
options and select “Collision/

{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

steps should be taken:
STEP ONE : Discuss your
concern with a member of
dealership management.
Normally, concerns can be
quickly resolved at that level.
