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 0297.
. 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. PARK ASSIST OFF :
If the PA system
does not activate due to a temporary
condition, the appropriate message
displays on the DIC. PA OFF message
is displayed when disabled by the
driver. Front/Rear PA OFF message is
displayed when an attached object is
detected in the front or rear
respectively. PA Temporarily
Unavailable message is displayed for
system failures. This can occur under
the following conditions:
. The driver has disabled the
system.
. An object was hanging out of the
trunk during the last drive cycle.
Once the object is removed, RPA
will return to normal operation.
. The bumper is damaged. Take the
vehicle to your dealer to repair the
system.
. Other conditions, such as
vibrations from a jackhammer or
the compression of air brakes on a
very large truck, are affecting
system performance.

210 DRIVING AND OPERATING
Backing Warning and Reverse
Automatic Braking
Vehicles with Adaptive Cruise Control
(ACC) have the Backing Warning
System and Reverse Automatic
Braking (RAB) system. The Backing
Warning part of this system can warn
of rear objects when backing up at
speeds greater than 8 km/h (5 mph),
and RAB will 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.
When the vehicle is in R (Reverse) and
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 below
the bumper or that are too close or
too far from the vehicle. To prevent
injury, death, or vehicle damage,
even with RAB, always check the
area around the vehicle before and
while backing.
If the brake pedal is not pressed soon
after the stop, the Electric Parking
Brake (EPB) may be set. When it is
safe, press the accelerator pedal firmly
at any time to override RAB.

DRIVING AND OPERATING 211
{Warning
There may be instances where
unexpected or undesired automatic
braking occurs. If this happens,
either press the brake pedal or
firmly press the accelerator pedal to
release the brakes from the RAB
system. Before releasing the brakes,
check the RVC and check the area
around the vehicle to make sure it
is safe to proceed.
Rear Cross Traffic Alert (RCTA)
If equipped, RCTA displays a red
warning triangle with a left or right
pointing arrow to warn of traffic
coming from the left or right. This
system detects objects coming from
up to 20 m (65 ft) from the left or
right side of the vehicle. When an
object is detected, either three beeps
sound from the left or right or three
Safety Alert Seat pulses occur on the
left or right side, depending on the
direction of the detected vehicle. 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.
See
Radio Frequency Statement 0334.
Turning the Features On or Off
TouchXon the center stack to turn
on or off the Front and Rear Park
Assist, Reverse Automatic Braking
(RAB), and the Backing Warning
System at the same time. The
indicator light next to the button
comes on when the features are on
and turns off when the features have
been disabled.
Turn off Park Assist, RCTA, and RAB
when towing a trailer.
To turn the RPA symbols or guidance
lines (on some models) on or off, see
“Rear Camera Park Assist Symbols”
under Vehicle Personalization 0124.
RCTA can also be turned on or off
through vehicle personalization. See
“Collision/Detection Systems” under
Vehicle Personalization 0124.
Automatic Parking Assist (APA)
with Braking
If equipped, APA searches for and
steers the vehicle into parallel and
perpendicular parking spots. When
using APA, you must still shift gears
while the system applies the brakes
and accelerator. A display and audible
beeps help to guide parking
maneuvers.
Do not use APA when towing a trailer.
{Warning
APA may not detect objects in the
parking space, objects that are soft
or narrow, objects high off the
ground such as flatbed trucks,
objects below ground level such as
large potholes, or moving objects
(e.g. pedestrians). Always verify that
the parking space is appropriate for
parking a vehicle. APA does not
respond to changes in the parking
space, such as movement of an
adjacent vehicle, or a person or
object entering the parking space.

steering to complete before continuing
the parking maneuver. APA will beep
and display a PARKING COMPLETE
message. Secure the vehicle against
rolling away by applying parking
brake.
APA may automatically disengage if:
.The steering wheel is used by the
driver.
. The maximum allowed speed is
exceeded.
. The parking brake is applied or the
vehicle is shifted into P (Park).
. There is a failure with the APA
system.
. Electronic stability control or
antilock brakes are activated.
. The driver opens the door with an
unbuckled seat belt.
The brake holds the vehicle until the
parking brake or brake is applied,
or the vehicle is shifted into P (Park).
To cancel APA, touch
Oagain. When the System Does Not Seem to
Work Properly
The APA system may require a short
period of driving along curves to
calibrate.
Rear Pedestrian Alert
Under certain conditions, this feature
can provide alerts for a pedestrian
within the system’s range directly
behind the vehicle. This feature only
works in R (Reverse) below 12 km/h
(8 mph), and detects pedestrians up to
8 m (26 ft) away during daytime
driving. During nighttime driving,
feature performance is very limited.
Rear Pedestrian Alert Indicator
When a pedestrian is detected within
the system’s range directly behind the
vehicle, this symbol flashes amber on
the infotainment display, along with
two beeps from the rear, or if equipped, two pulses from both sides
of the driver seat. When a pedestrian
is detected close to the vehicle, the
symbol flashes red on the
infotainment display, along with seven
beeps from the rear, or if equipped,
seven pulses from both sides of the
driver seat.
{Warning
Rear Pedestrian Alert does not
automatically brake the vehicle.
It also does not provide an alert
unless it detects a pedestrian, and it
may not detect all pedestrians if:
. The pedestrian is not directly
behind the vehicle, fully
visible to the Rear Vision
Camera (RVC), or standing
upright.
. The pedestrian is part of a
group.
. The pedestrian is a child.

Warning (Continued)
.Visibility is poor, including
nighttime conditions, fog,
rain, or snow.
. The RVC is blocked by dirt,
snow, or ice.
. The RVC, taillamps,
or back-up lamps are not
cleaned or in proper working
condition.
. The vehicle is not in
R (Reverse).
To help avoid death or injury,
always check for pedestrians
around the vehicle before backing
up. Be ready to take action and
apply the brakes. See Defensive
Driving 0150. Keep the RVC,
taillamps, and back-up lamps clean
and in good repair.
Rear Pedestrian Alert can be set to Off
or Alert. See “Rear Pedestrian
Detection ”in “Collision/Detection
Systems” underVehicle Personalization
0 124. If equipped, alerts can be set to beeps or seat pulses. See
“Alert Type”
in “Collision/Detection Systems” under
Vehicle Personalization 0124.
Assistance Systems for
Driving
If equipped, when driving the vehicle
in a forward gear, Forward Collision
Alert (FCA), 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
If equipped, 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 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 is equipped
with Adaptive Cruise Control (ACC),
the FCA timing setting can only be
changed while ACC is not engaged.
See
Adaptive Cruise Control 0195.
{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 0150.

Cadillac CT5 Owner Manual (GMNA-Localizing-U.S./Canada-13060105) -

DRIVING AND OPERATING 215
FCA can be disabled with either the
FCA steering wheel control or,
if equipped, through vehicle
personalization. See“Collision/
Detection Systems” underVehicle
Personalization 0124.
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.
Cruise control may be disengaged
when the Collision Alert occurs.
Tailgating Alert

Cadillac CT5 Owner Manual (GMNA-Localizing-U.S./Canada-13060105) -
2020 - CRC - 2/14/20
216 DRIVING AND OPERATING
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,
or on some vehicles, Off. 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), the
FCA timing setting can only be
changed while (ACC) is not engaged.
See Adaptive Cruise Control.
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)
0117.
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)
If the vehicle has Forward Collision
Alert (FCA), it also has AEB, which
includes Intelligent Brake Assist (IBA).
When the system detects a vehicle
ahead in your path that is traveling in
the same direction that you may be
about to 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

Cadillac CT5 Owner Manual (GMNA-Localizing-U.S./Canada-13060105) -
2020 - CRC - 2/14/20
DRIVING AND OPERATING 217
on the situation, the vehicle may
automatically brake moderately or
hard. This automatic emergency
braking can only occur if a vehicle is
detected. This is shown by the FCA
vehicle ahead indicator being lit. See
Forward Collision Alert (FCA) System
0214.
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: (Continued)
Warning (Continued)
.Detect a vehicle ahead on
winding or hilly roads.
. Detect all vehicles, especially
vehicles with a trailer,
tractors, muddy vehicles, etc.
. 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.

218 DRIVING AND OPERATING
{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 personalization. See “Collision/
Detection Systems” underVehicle
Personalization 0124.
{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 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) 0216. 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. If the vehicle is
equipped with the Night Vision
system, during nighttime driving, the
vehicle can detect and alert to
pedestrians whenever in a
forward gear.
{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.

. If the headlamps or
windshield are not cleaned or
in proper condition.
Be ready to take action and apply
the brakes. For more information,
see Defensive Driving 0150. 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 0124.
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.
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
