icon on the infotainment home
page. Select“Vehicle”to
display the list of available
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

deceleration. Continue to
apply the brake pedal as
needed.
Tailgating Alert
The vehicle ahead indicator
will display amber when you
are following a vehicle ahead
much too closely.
Selecting the Alert Timing
The Collision Alert control is
on the steering wheel. Press
[to set the FCA timing to
Far, Medium, or Near. The first
button press shows the
current setting on the DIC. Additional button presses will
change this setting. The
chosen setting will remain until
it is changed and will affect
the timing of both the Collision
Alert and the Tailgating Alert
features. The timing of both
alerts will vary based on
vehicle speed. The faster the
vehicle speed, the farther
away the alert will occur.
Consider traffic and weather
conditions when selecting the
alert timing. The range of
selectable alert timings may
not be appropriate for all
drivers and driving conditions.
If your vehicle is equipped with
Adaptive Cruise Control (ACC),
changing the FCA timing
setting automatically changes
the following gap setting (Far,
Medium, or Near).
Following Distance
Indicator
The following distance to a
moving vehicle ahead in your
path is indicated in following
time in seconds on the DriverInformation Center (DIC). See
Driver Information Center
(DIC) (Base Level)
0129 or
Driver Information Center
(DIC) (Uplevel) 0132. 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.

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

.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)
System0342. 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.
(Continued)
Warning (Continued)
.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.

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) -

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.

vehicle could be damaged.
To help avoid injury to you
and others:
.Dispense fuel only into
approved containers.
.Do not fill a container
while it is inside a vehicle,
in a vehicle's trunk, in a
pickup bed, or on any
surface other than the
ground.
.Bring the fill nozzle in
contact with the inside of
the fill opening before
operating the nozzle.
Maintain contact until
filling is complete.
.Keep sparks, flames, and
smoking materials away
from fuel.
.Avoid using electronic
devices while
pumping fuel.
Trailer Towing
General Towing
Information
Only use towing equipment
that has been designed for the
vehicle. Contact your dealer or
trailering dealer for assistance
with preparing the vehicle to
tow a trailer. Read the entire
section before towing a trailer.
To tow a disabled vehicle, see
Transporting a Disabled
Vehicle (Electronic Shifter)
0450 or
Transporting a Disabled
Vehicle (Mechanical Shifter)
0 452. To tow the vehicle
behind another vehicle such as
a motor home, see
Recreational Vehicle Towing
0 454.
When towing with the 2.0L L4
engine, only use unleaded
gasoline with an octane rating
of 89 or higher. Using gasoline
with a lower octane rating while towing may damage the
engine and may not be
covered by the vehicle
warranty. See Recommended
Fuel (LSY 2.0L L4 Turbo
Engine)
0354 or

Driving
Characteristics and
Towing Tips
{Warning
You can lose control when
towing a trailer if the correct
equipment is not used or the
vehicle is not driven
properly. For example, if the
trailer is too heavy or the
trailer brakes are
inadequate for the load, the
vehicle may not stop as
expected. You and others
could be seriously injured.
The vehicle may also be

360 Driving and Operating
If equipped, the following
driver assistance features
should be turned to alert or
off when towing a trailer:
.Automatic Emergency
Braking (AEB)
.Intelligent Brake Assist (IBA)
.Front Pedestrian
Braking (FPB)
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.
If equipped with Rear Cross
Traffic Alert (RCTA), use
caution while backing up when
towing a trailer, as the RCTA
detection zones that extend
out from the back of the
vehicle do not move further
back when a trailer is towed.
{Warning
To prevent serious injury or
death from carbon monoxide
(CO), when towing a trailer:
.Do not drive with the
liftgate, trunk/hatch,
or rear-most
window open.
.Fully open the air outlets
on or under the
instrument panel.
.Adjust the climate control
system to a setting that
brings in only outside air.
See “Climate Control
Systems” in the Index.
For more information about
carbon monoxide, see
Engine Exhaust 0271.
Towing a trailer requires
experience. The combination
of the vehicle and trailer is
longer and not as responsive
as the vehicle itself. Become
familiar with handling and braking by driving on a level
road surface before driving on
public roads.
The trailer structure, the tires,
and the brakes must be all be
rated to carry the intended
cargo. Inadequate trailer
equipment can cause the
combination to operate in an
unexpected or unsafe manner.
Before driving, inspect all
trailer hitch parts and
attachments, safety chains,
electrical connectors, lamps,
tires, and mirrors. See Towing
Equipment
0365. If the trailer
has electric brakes, start the
combination moving and then
manually apply the trailer
brake controller to check the
trailer brakes work. During the
trip, occasionally check that
the cargo and trailer are
secure and that the lamps and
any trailer brakes are working.
