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),
Front Pedestrian Braking
(FPB) System, and/or the
Night Vision 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 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)
0283.
{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.
(Continued)
Warning (Continued)
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
Driving0240.

334 Driving and Operating
1. Low-Beam Headlamps
2. High-Beam Headlamps
3. Night Vision System
By selecting a view on the
instrument cluster, the Night
Vision image can be displayed.
See Instrument Cluster0127.
The Night Vision system can
operate only if:
.The ignition is on.
.The vehicle is in P (Park) or a
forward gear.
.It is dark enough outside.
.The headlamps are on,
except when parked. Adjust the instrument panel
brightness to make the image
no brighter than necessary.
Turn the image off by
selecting another view on the
instrument cluster.
Warm objects, such as
pedestrians, animals, and
other moving vehicles, should
appear whiter on the Night
Vision display. Cold objects,
such as the sky, signs, and
parked vehicles, should appear
darker. Night Vision 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,
~,
or animal icon,
!, displays on
the instrument cluster. This
pedestrian icon is also shown
on the Head-Up Display (HUD).
When the system detects the
vehicle is approaching a
pedestrian too quickly, the
amber pedestrian icon and box
turns red, and a red flashing
icon,
~, displays on the HUD
with rapid beeping or pulsing
of the Safety Alert Seat,
if equipped.

adjustment, see your dealer.
Do not attempt to adjust the
camera yourself.
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 that
occur with moving vehicles in
the side blind zone (or spot)
areas or with vehicles rapidly
approaching these areas from
behind. The LCA warning
display will light up in the
corresponding outside side
mirror and will flash if the turn
signal is on.
{Warning
LCA does not alert the
driver to vehicles outside of
the system detection zones,
pedestrians, bicyclists,
or animals. It may not
provide alerts when
changing lanes under all
driving conditions. Failure to
use proper care when
changing lanes may result in(Continued)
Warning (Continued)
injury, death, or vehicle
damage. Before making a
lane change, always check
mirrors, glance over your
shoulder, and use the turn
signals.
LCA Detection Zones
1. SBZA Detection Zone
2. LCA Detection Zone
The LCA sensor covers a zone
of approximately one lane over
from both sides of the vehicle,
or 3.5 m (11 ft). The height of
the zone is approximately
between 0.5 m (1.5 ft) and 2 m
(6 ft) off the ground. The Side

Blind Zone Alert (SBZA)
warning area starts at
approximately the middle of
the vehicle and goes back 5 m
(16 ft). Drivers are also warned
of vehicles rapidly
approaching from up to 70 m
(230 ft) behind the vehicle.
How the System Works
The LCA symbol lights up in
the side mirrors when the
system detects a moving
vehicle in the next lane over
that is in the side blind zone or
rapidly approaching that zone
from behind. A lit LCA symbol
indicates it may be unsafe to
change lanes. Before making a
lane change, check the LCA
display, check mirrors, glance
over your shoulder, and use
the turn signals.
Left Side
Mirror DisplayRight Side
Mirror Display
When the vehicle is started,
both outside mirror LCA
displays will briefly come on to
indicate the system is
operating. 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 the next lane over
in that blind zone or rapidly
approaching that zone. If the
turn 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 through
vehicle settings. When you
disable LCA, SBZA is also
disabled.To view available
settings from the infotainment screen, touch Settings >
Vehicle > Collision/Detection
Systems. 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

Cadillac XT6 Owner Manual (GMNA-Localizing-U.S./Canada-16405819) -
2023 - CRC - 3/22/22
338 Driving and Operating
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 Care
0440. 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.

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. The LKA
can be ready to assist at
speeds between 60 km/h
(37 mph) and 180 km/h
(112 mph). On some vehicles, the system will instead
operate above 50 km/h
(31 mph). LKA 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. This system is not
intended to keep the vehicle
centered in the lane. LKA will
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. LKA can be
overridden by turning the
steering wheel. If the system
detects you are steering
intentionally across a lane
marker, the LDW may not be
given. Do not expect the LDW
to occur when you are
intentionally crossing a lane
marker.

departure. It may further
provide an audible alert or the
driver seat may pulse
indicating that a lane marking
has been crossed. The system
does not provide a Lane
Departure Warning (LDW)
when intentionally steering
across a lane marker.
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. In some
vehicles a long press of over
three seconds is required to
turn LKA off.
When on,
Ais white,
if equipped, indicating that the
system is not ready to assist.
Ais green if LKA is ready to
assist. LKA may assist by
gently turning the steering
wheel if the vehicle
approaches a detected lane
marking.
Ais amber when
assisting. It may also provide a
Lane Departure Warning (LDW) alert by flashing
A
amber if the vehicle crosses a
detected lane marking.
Additionally, there may be
three beeps, or the driver seat
may pulse three times, on the
right or left, depending on the
lane departure direction.
Take Steering
The LKA system does not
continuously steer the vehicle.
If LKA does not detect active
driver steering, an alert and
chime may be provided. Steer
the vehicle to dismiss. LKA
may become temporarily
unavailable after repeated
take steering alerts.
When the System Does
Not Seem to Work
Properly
The system performance may
be affected by:
.Close vehicles ahead.
.Sudden lighting changes,
such as when driving
through tunnels.
.Banked roads.
.Roads with poor lane
markings, such as two-lane
roads.
If the LKA system is not
functioning properly when lane
markings are clearly visible,
cleaning the windshield
may help.
A camera blocked message
may display if the camera is
blocked. Some driver
assistance systems may have
reduced performance or not
work at all. An LKA or LDW
unavailable message may
display if the systems are
temporarily unavailable. This
message could be due to a
blocked camera. The LKA
system does not need service.
Clean the outside of the
windshield behind the
rearview mirror.
LKA assistance and/or LDW
alerts may occur due to tar
marks, shadows, cracks in the
road, temporary or
construction lane markings,

the engine compartment fuse
block. The electric trailer brake
controller should be installed
by your dealer or a qualified
service center.
Trailer Lamps
Always check that all trailer
lamps are working at the
beginning of each trip, and
periodically on longer trips.
Turn Signals When
Towing a Trailer
When properly connected, the
trailer turn signals will
illuminate to indicate the
vehicle is turning, changing
lanes, or stopping. When
towing a trailer, the arrows on
the instrument cluster will
illuminate even if the trailer is
not properly connected or the
bulbs are burned out.
Trailer Sway
Control (TSC)
Vehicles with StabiliTrak/
Electronic Stability Control
(ESC) have a Trailer Sway
Control (TSC) feature. Trailer
sway is unintended
side-to-side motion of a trailer
while towing. If the vehicle is
towing a trailer and the TSC
detects that sway is
increasing, the vehicle brakes
are selectively applied to help
reduce excessive trailer sway.
If equipped with the
Integrated Trailer Brake
Control (ITBC) system, and the
trailer has an electric brake
system, StabiliTrak/ESC may
also apply the trailer brakes.
If TSC is enabled, the Traction
Control System (TCS)/
StabiliTrak/ESC warning light
will flash on the instrument
cluster. Reduce vehicle speed
by gradually removing your
foot from the accelerator
pedal. If trailer sway continues,
StabiliTrak/ESC can reduce
engine torque to help slow the
vehicle. TSC will not function if
StabiliTrak/ESC is turned off.
See Traction Control/
Electronic Stability Control
0276.
{Warning
Trailer sway can result in a
crash and in serious injury or
death, even if the vehicle is
equipped with TSC.
If the trailer begins to sway,
reduce vehicle speed by
gradually removing your foot
from the accelerator. Then
pull over to check the trailer
and vehicle to help correct
possible causes, including an

improperly or overloaded
trailer, unrestrained cargo,
improper trailer hitch
configuration, or improperly
inflated or incorrect vehicle
or trailer tires. See Towing
Equipment0356 for trailer
ratings and hitch setup
recommendations.
Trailer Tires
Special Trailer (ST) tires differ
from vehicle tires. Trailer tires
are designed with stiff
sidewalls to help prevent sway
and to support heavy loads.
These features can make it
difficult to determine if the
trailer tire pressures are low
only based on a visual
inspection.
Always check all trailer tire
pressures before each trip
when the tires are cool. Low
trailer tire pressure is a
leading cause of trailer tire
blowouts. Trailer tires deteriorate over
time. The trailer tire sidewall
will show the week and year
the tire was manufactured.
Many trailer tire
manufacturers recommend
replacing tires more than six
years old.
Overloading is another leading
cause of trailer tire blowouts.
Never load the trailer with
more weight than the tires are
designed to support. The load
rating is on the trailer tire
sidewall.
Always know the maximum
speed rating for the trailer
tires before driving. This may
be significantly lower than the
vehicle tire speed rating. The
speed rating may be on the
trailer tire sidewall. If the
speed rating is not shown, the
default trailer tire speed rating
is 105 km/h (65 mph).

3. When it is safe to do so,pull off the road, shift to
P (Park) or N (Neutral), and
let the engine idle.
If the engine coolant
temperature gauge is no
longer in the overheated area
or the engine coolant
temperature warning light no
longer displays, the vehicle
can be driven. Continue to
drive the vehicle slowly for
about 10 minutes. Keep a safe
distance from the vehicle in
front. If the warning does not
come back on, continue to
drive normally and have the
cooling system checked for
proper fill and function.
If the warning continues, pull
over, stop, and park the
vehicle right away.
If there is no sign of steam,
idle the engine for
three minutes while parked.
If the warning is still displayed,
turn off the engine until it
cools down.Washer Fluid
What to Use
When windshield washer fluid
is needed, be sure to read the
manufacturer's instructions
before use. If operating the
vehicle in an area where the
temperature may fall below
freezing, use a fluid that has
sufficient protection against
freezing.
Adding Washer Fluid
The appropriate message will
appear in the Driver
Information Center (DIC) when
the fluid level is low.
Open the cap with the washer
symbol on it. Add washer fluid until the tank is full. See
Engine Compartment
Overview
0367 for reservoir
location.
Caution
.Do not use washer fluid
that contains any type of
water repellent coating.
This can cause the wiper
blades to chatter or skip.
.Do not use engine coolant
(antifreeze) in the
windshield washer. It can
damage the windshield
washer system and paint.
.Do not mix water with
ready-to-use washer fluid.
Water can cause the
solution to freeze and
damage the washer fluid
tank and other parts of
the washer system.
.When using concentrated
washer fluid, follow the
manufacturer instructions
for adding water.
