How the System Works
The instrument cluster may
have a Park Assist display with
bars that show“distance to
object,” driving direction, and
object location information for
the Park Assist system. As the
object gets closer, more bars
light up and the bars change
color from yellow to amber
to red.
Beeps sound to warn the
driver of certain objects that
are detected around the
vehicle. The frequency of
beeps increases as the vehicle
gets closer to the object.
When the object is very close
to the vehicle, the beeps are
continuous. Beeps for the
front are higher pitched than
beeps for the rear. If equipped
with Safety Alert seat, both
sides of the seat will pulse
alongside the beeps. When the System Does Not
Seem to Work Properly
The following messages may
be displayed on the DIC:

Reverse Automatic
Braking (RAB)
Backing Warning and
Reverse Automatic
Braking (RAB)
If equipped, vehicles with
Adaptive Cruise Control (ACC)
have the Backing Warning
System and Reverse
Automatic Braking (RAB)
system. When in R (Reverse),
Backing Warning alerts of rear
objects at vehicle speeds
greater than 8 km/h (5 mph),
and RAB may automatically
brake hard at speeds between
1–32 km/h (0.5–20 mph).
The Backing Warning System
will beep once from the rear
when an object is first
detected, or pulse twice on
both sides of the Safety Alert
Seat. When the system
detects a potential crash,
beeps will be heard from the
rear, or five pulses will be felt
on both sides of the Safety Alert Seat. There may also be
a brief, sharp application of
the brakes.
{Warning
The Backing Warning
System only operates at
speeds greater than 8 km/h
(5 mph). It does not detect
children, pedestrians,
bicyclists, animals, or objects
below the bumper or that
are too close or too far from
the vehicle. In some
situations, such as at higher
backing speeds, there may
not be enough time for the
short, sharp application of
the vehicle brake system to
occur. To prevent injury,
death, or vehicle damage,
even with the Backing
Warning System, always
check the area around the
vehicle and check all mirrors
before backing.

Driving and Operating 341
When the vehicle is in
R (Reverse), if the system
detects the vehicle is backing
too fast to avoid a crash with
a detected object behind your
vehicle in your path, it may
automatically brake hard to a
stop to help avoid or reduce
the harm caused by a backing
crash.
{Warning
RAB may not avoid many
types of backing crashes. Do
not wait for the automatic
braking to apply. This
system is not designed to
replace driver braking and
only works in R (Reverse)
when an object is detected
directly behind the vehicle.
It may not brake or stop in
time to avoid a crash. It will
not brake for objects when
the vehicle is moving at very
low speeds. It does not
detect children, pedestrians,
bicyclists, animals, or objects(Continued)

Assistance Systems
for Driving
If equipped, when driving the
vehicle in a forward gear,
Forward Collision Alert (FCA),
Lane Departure Warning
(LDW), Lane Keep Assist (LKA), Side Blind Zone Alert
(SBZA), Lane Change Alert
(LCA), Automatic Emergency
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
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 detects vehicles within a
distance of approximately
60 m (197 ft) and operates at
speeds above 8 km/h (5 mph).
If the vehicle has Adaptive
Cruise Control (ACC), it can
detect vehicles to distances of
approximately 110 m (360 ft)
and operates at all speeds.
See Adaptive Cruise Control
(Advanced)
0304.
{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. See Defensive
Driving 0235.

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) -

Driving and Operating 345
.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.

{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
