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

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.

0477.
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.

{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.
.Detect lanes on winding or
hilly roads.(Continued)
Warning (Continued)
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 on slippery roads
could cause loss of control
of the vehicle and a crash.
Turn the system off.
{Warning
LKA will not alert the driver
if a towed trailer crosses
into an adjacent lane of
travel. Serious injury or
property damage may occur
if the trailer moves into
another lane. Always
monitor the trailer position
while towing to make sure it
is within the same lane as
the tow vehicle.
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

Cadillac XT6 Owner Manual (GMNA-Localizing-U.S./Canada-16405819) -

340 Driving and Operating
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,

towing, install extended side
view mirrors, even if not
required.
.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.
.GM recommends performing
an oil change to the vehicle
before heavy towing.
.Do not drive over 80 km/h
(50 mph) and do not make
starts at full throttle during
the first 800 km (500 mi) of
trailer towing.
.Vehicles can tow in D (Drive).
If the transmission
downshifts too often, a
lower gear may be selected
using Manual Mode. See
Manual Mode0271.
If equipped, the following
driver assistance features
should be turned off when
towing a trailer:
.Adaptive Cruise
Control (ACC)
.Super Cruise Control
.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)
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.
.Adjust the climate control
system to a setting that
brings in only outside air.
See
“Climate Control
Systems” in the Index.
