Park Assist
The vehicle may be equipped with the
Rear Park Assist (RPA) or Front and
Rear Park Assist (FRPA). The Park
Assist system may provide assistance
to driver when backing up and
parking. Park Assist uses ultrasonic
sensors in the bumpers to measure
the distance between the vehicle and
objects. The system calculates the
distance between vehicle and object
via measuring the time it takes for the
ultrasonic waves to bounce back from
the object. Park Assist works only at
speeds up to about 11 Km/h (7 mph).
An illuminated LED in the parking
assist button indicates that the
system is ready to operate. The
sensors on the bumpers may detect
objects up to 1.8m (6 ft) behind and
1.25m (4 ft) in front of the vehicle
within a zone 25 cm (10 in) high off
the ground and below bumper level.

298 DRIVING AND OPERATING
These detection distances may be
shorter during warmer or humid
weather. Blocked sensors will not
detect objects and can also cause false
detections. Keep the sensors clean of
mud, dirt, snow, ice, and slush; and
clean sensors after a car wash in
freezing temperatures.
{Warning
The Park Assist System is no
substitute for careful and attentive
driving. The Park Assist system
does not detect children,
pedestrians, bicyclists, animals,
or objects located below the
bumper or that are too close or too
far from the vehicle. It is not
available at speeds greater than
11 km/h (7 mph). To prevent injury,
death, or vehicle damage, even with
Park Assist, always check the area
around the vehicle and check all
mirrors before moving forward or
backing.
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.
When an object is very close to the
vehicle rear (<0.6m (2 ft)), five beeps
will sound from the rear followed by a
continuous beep from the rear,
or both sides of the Safety Alert Seat
will pulse five times. When an object
is very close to the vehicle front
(<0.3m (1 ft)), a continuous beep will
sound from the front, or both sides of the Safety Alert Seat will pulse five
times. Beeps for FPA are higher
pitched than for RPA.
When the System Does Not Seem to
Work Properly
The following messages may be
displayed on the DIC:
SERVICE PARKING ASSIST :
If this
message occurs, check the following
conditions:
.The sensors are not clean. Keep the
vehicle's rear bumper free of mud,
dirt, snow, ice, and slush. For
cleaning instructions, see Exterior
Care 0397.
.The Park Assist sensors are covered
by frost or ice. Frost or ice can form
around and behind the sensors and
may not always be seen; this can
occur after washing the vehicle in
cold weather. The message may not
clear until the frost or ice has
melted.
If the above conditions do not exist,
take the vehicle to your dealer to
repair the system.

302 DRIVING AND OPERATING
{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 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

Cadillac CT4 Owner Manual (GMNA-Localizing-U.S./Canada-15283641) -
2022 - CRC - 10/12/21
DRIVING AND OPERATING 303
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
Driver Information Center (DIC). See
Driver Information Center (DIC) (Base
Level)0109 or
Driver Information Center (DIC)
(Uplevel) 0112. 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.
.Clean the headlamps.
Automatic Emergency
Braking (AEB)
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,
it can provide a boost to braking,
or automatically brake the vehicle, to
avoid a crash. 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. When detecting a vehicle,
the Forward Collision Alert (FCA)
vehicle ahead indicator light will be
on. See
Forward Collision Alert (FCA)
System 0301.
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. (Continued)

DRIVING AND OPERATING 305
.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 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) 0303.
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,
seeDefensive Driving 0210. 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.
See “Front Pedestrian Detection ”in
“Collision/Detection Systems” under
Vehicle Personalization 0120.
Detecting the Pedestrian Ahead
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.
