{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.
{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 0410.
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 0123.
RCTA can also be turned on or off
through vehicle personalization. See
“Collision/Detection Systems” under
Vehicle Personalization 0123.

DRIVING AND OPERATING 283
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.
APA does not detect or avoid traffic(Continued)
Warning (Continued)
that is behind or alongside of the
vehicle. Always be prepared to stop
the vehicle during the parking
maneuver.
Touch
Oon the center stack to
enable the system to search for a
parking space that is large enough and
within 1.5 m (5 ft) of the vehicle. The
vehicle speed must be below
30 km/h (18 mph). The system cannot:
.Detect whether it is a legal parking
space.
.Park exactly lined up with the
vehicle next to it if the spot is
approached at an angle or if the
parking space is angled.
.Park exactly centered in a spot that
is marked too large.
.Always detect short curbs.
When enabled, APA searches for
parallel parking spaces to the right of
the vehicle. To search for a parking
space to the left, turn on the left turn
signal or, if available, change the side
selection in the infotainment display.
To switch the parking mode between parallel and perpendicular, change the
parking mode in the infotainment
display.
After completely passing a large
enough space, an audible beep occurs.
A red stop symbol and a shift to
reverse message are displayed.
If the vehicle is in R (Reverse), but
does not steer into the expected
space, this may be because the system
is maneuvering the vehicle into a
previously detected space. The APA
system does not need service.

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 personalization. See
“Collision/
Detection Systems” underVehicle
Personalization 0123.
{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 if the
vehicle has ACC to 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) 0288.
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

Cadillac CT5 Owner Manual (GMNA-Localizing-U.S./Canada-14584312) -
2021 - CRC - 11/23/20
DRIVING AND OPERATING 291
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 also
equipped with the Night Vision
system, pedestrians detected by the
Night Vision system will not cause
automatic braking to occur.
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.
Automatic Braking can be disabled
through vehicle personalization. See
“Front Pedestrian Detection ”in
“Collision/Detection Systems” under
Vehicle Personalization 0123.
{Warning
Using the Front Pedestrian Braking
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

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. See“Collision/Detection
Systems” underVehicle Personalization
0 123. 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
highway road with traffic and roadside
objects (e.g., guardrails, barriers).
LCA displays may not come on when
passing a vehicle quickly, for a
stopped vehicle, or when towing a
trailer. 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. LCA may alert to objects
attached to the vehicle, such as a
trailer, bicycle, or object extending out
to either side of the vehicle. Attached
objects may also interfere with the
detection of vehicles. This is normal
system operation; the vehicle does not
need service.
LCA may not always alert the driver to
vehicles in the next lane over,
especially in wet conditions or when
driving on sharp curves. The system
does not need to be serviced. The
system may light up due to guardrails,
signs, trees, shrubs, and other
non-moving objects. This is normal
system operation; the vehicle does not
need service.
LCA may not operate when the LCA
sensors in the left or right corners of
the rear bumper are covered with
mud, dirt, snow, ice, or slush, or in
heavy rainstorms. For cleaning
instructions, see "Washing the
Vehicle" under
Exterior Care0372.
If the DIC still displays the system
unavailable message after cleaning both sides of the vehicle toward the
rear corners of the vehicle, see your
dealer.
If the LCA displays do not light up
when moving vehicles are in the side
blind zone or are rapidly approaching
this zone and the system is clean, the
system may need service. Take the
vehicle to your dealer.
Radio Frequency Information
See
Radio Frequency Statement 0410.
Lane Keep Assist (LKA)
If equipped, LKA may help avoid
crashes due to unintentional lane
departures. This system uses a camera
to detect lane markings between
60 km/h (37 mph) and 180 km/h
(112 mph). It may assist by gently
turning the steering wheel if the
vehicle approaches a detected lane
marking. It may also provide a Lane
Departure Warning (LDW) alert if the
vehicle crosses a detected lane
marking. LKA can be overridden by
turning the steering wheel. This
system is not intended to keep the
vehicle centered in the lane. LKA will

294 DRIVING AND OPERATING
not assist and alert if the turn signal
is active in the direction of lane
departure, or if it detects that you are
accelerating, braking or actively
steering.
{Warning
The LKA system does not
continuously steer the vehicle.
It may not keep the vehicle in the
lane or give a Lane Departure
Warning (LDW) alert, even if a lane
marking is detected.
The LKA and LDW systems
may not:
.Provide an alert or enough
steering assist to avoid a lane
departure or crash.
.Detect lane markings under poor
weather or visibility conditions.
This can occur if the windshield
or headlamps are blocked by dirt,
snow, or ice; if they are not in
proper condition; or if the sun
shines directly into the camera.
.Detect road edges.(Continued)
Warning (Continued)
.Detect lanes on winding or hilly
roads.
If LKA only detects lane markings
on one side of the road, it will only
assist or provide an LDW alert
when approaching the lane on the
side where it has detected a lane
marking. Even with LKA and LDW,
you must steer the vehicle. Always
keep your attention on the road and
maintain proper vehicle position
within the lane, or vehicle damage,
injury, or death could occur. Always
keep the windshield, headlamps,
and camera sensors clean and in
good repair. Do not use LKA in bad
weather conditions or on roads with
unclear lane markings, such as
construction zones.
{Warning
Using LKA while towing a trailer or
on slippery roads could cause loss
of control of the vehicle and a
crash. Turn the system off.
How the System Works
LKA uses a camera sensor installed on
the windshield ahead of the rearview
mirror to detect lane markings. It may
provide brief steering assist if it
detects an unintended lane departure.
It may further provide an audible alert
or the driver seat may pulse indicating
that a lane marking has been crossed.
To turn LKA on and off, press
Aon
the center stack. If equipped, the
indicator light on the button comes
on when LKA is on and turns off
when LKA is disabled.
When on,

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 damaged,
and the repairs would not be
covered by the vehicle warranty.
Pull a trailer only if all the steps in
this section have been followed. Ask
your dealer for advice and
information about towing a trailer
with the vehicle.
Driving with a Trailer
Trailering is different than just driving
the vehicle by itself. Trailering means
changes in handling, acceleration,
braking, durability, and fuel economy.
Successful, safe trailering takes correct
equipment, and it has to be used
properly.
The following information has many
time-tested, important trailering tips
and safety rules. Many of these are
important for your safety and that of
your passengers. Read this section
carefully before pulling a trailer.
When towing a trailer:
.Become familiar with and follow all
state and local laws that apply to
trailer towing. These requirements
vary from state to state.
.State laws may require the use of
extended side view mirrors. Even if
not required, you should install
extended side view mirrors if your
visibility is limited or restricted
while towing.
.Do not tow a trailer during the first
800 km (500 mi) of vehicle use to
prevent damage to the engine, axle,
or other parts.
.It is recommended to perform the
first oil change before heavy towing.
.During the first 800 km (500 mi) of
trailer towing, do not drive over
80 km/h (50 mph) and do not make
starts at full throttle.
.Vehicles can tow in D (Drive). If the
transmission downshifts too often, a
lower gear may be selected using
Manual Mode. See Manual Mode
0 236.
If equipped, the following driver
assistance features should be turned
off when towing a trailer:
.Adaptive Cruise Control (ACC)
.Super Cruise Control
.Lane Keep Assist (LKA)
.Park Assist
.Automatic Parking Assist (APA)
.Reverse Automatic Braking (RAB)
If equipped, the following driver
assistance features should be turned
to alert or off when towing a trailer:
