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(Continued)
Warning (Continued)
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.

DRIVING AND OPERATING 229
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
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
0226.
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.
. 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.

Cadillac XT6 Owner Manual (GMNA-Localizing-U.S./Canada-12984300) -
2020 - CRC - 3/19/19
230 DRIVING AND OPERATING
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 0135.
{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)
0 229.
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.
Be ready to take action and apply
the brakes. For more information,
see Defensive Driving 0166. Keep
the windshield, headlamps, and FPB
sensor clean and in good repair. FPB can be set to Off, Alert, or Alert
and Brake through vehicle
personalization. See
“Collision/
Detection Systems” underVehicle
Personalization 0135.
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 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.Automatic Braking can be disabled
through vehicle personalization. See
“Front Pedestrian Detection
”in
“Collision/Detection Systems” under
Vehicle Personalization 0135.
{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.
Night Vision System
If equipped, this system can help the
driver see and alert the driver to
pedestrians or large animals ahead of
the vehicle beyond the area lit by the
headlamps. A thermal heat image of
the view ahead is displayed when it is dark enough outside. If a pedestrian
or large animal is detected more than
25 m (82 ft) away, an amber
pedestrian or animal icon displays and
a box appears around the pedestrian
or animal. When the system detects
that the vehicle is approaching a
pedestrian ahead much too quickly,
the box changes to red.
With the Front Pedestrian Braking
system turned on, Night Vision
provides a red Head-Up Display (HUD)
alert when the system detects that the
vehicle is approaching a pedestrian
ahead much too quickly. In addition,
an alert beeps or the Safety Alert Seat
pulses, if equipped. See
Front
Pedestrian Braking (FPB) System 0230.

only shows objects that are warmer or
colder than the surroundings. It does
not detect brake lamps, turn signals,
emergency flashers, traffic lights,
or sign information. Use this system as an aid by
occasionally glancing at the image. Do
not stare at the image or use the
image under well-lit conditions.
{Warning
Do not stare at the image while
driving as this might cause
important objects ahead not to be
seen. You could crash, and you or
others could be injured.
When a pedestrian or large animal is
detected, an amber box displays
around the pedestrian or animal on
the Night Vision display and an amber
pedestrian icon,

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 Towing
the Vehicle 0320. To tow the vehicle
behind another vehicle such as a
motor home, see Recreational Vehicle
Towing 0321.
Driving Characteristics and
Towing Tips
{Warning
You can lose control when towing a

Warning (Continued)
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 areimportant 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 0195.
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:
. Automatic Emergency
Braking (AEB)
. Intelligent Brake Assist (IBA)
. Front Pedestrian Braking (FPB)

Cadillac XT6 Owner Manual (GMNA-Localizing-U.S./Canada-12984300) -

246 DRIVING AND OPERATING
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.
(Continued)
Warning (Continued)
.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
0 189.
Towing a trailer requires experience.
The combination of the vehicle and
trailer is longer and not as responsive
as the vehicle itself. Get used to the
handling and braking of the
combination 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 0252. 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.
Towing with a Stability Control
System
When towing, the stability control
system might be heard. The system
reacts to vehicle movement caused by
the trailer, which mainly occurs
during cornering. This is normal when
towing heavier trailers.
Following Distance
Stay at least twice as far behind the
vehicle ahead as you would when
driving without a trailer. This can help
to avoid heavy braking and sudden
turns.
Passing
More passing distance is needed when
towing a trailer. The combination of
the vehicle and trailer will not
accelerate as quickly and is much
longer than the vehicle alone. It is
