Automatic Parking
Assist (APA)
Automatic Parking Assist
(APA) with Braking
If equipped, under certain
conditions APA with Braking
can use sensors based on
sonar technology along the
vehicle’s front, rear and sides
to detect a parking spot, and
automatically park the vehicle
with some driver assistance.
The vehicle will automatically
maneuver into a detected spot
moving at or near idle speed.
It does this by automatically
steering and braking while the
driver is responsible for
acceleration and gear shifting
as needed. The driver must
always be prepared to apply
braking or additional
acceleration, as needed.A display and audible beeps
help to guide the parking
maneuvers.
{Warning
APA may not always detect
objects in the parking space,
objects that are not rigid
(e.g. shrubs and chain-link
fences), objects below the
bumper, objects high off the
ground (e.g. flatbed trucks),
hanging objects, objects
below ground level (e.g. large
potholes), or moving objects
(e.g. pedestrians, cyclists,
vehicles). Always verify that
the parking space is
appropriate for parking a
vehicle. APA may 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 that is

behind or alongside of the
vehicle. Always be prepared
to stop the vehicle during
the parking maneuver.
How to Activate Automatic
Parking
To activate APA, press the
soft-touch button or hard
switch
Ofor the system to
begin searching for a parking
space while driving forward at
no greater than
30 km/h (18 mph). By default,
APA searches for parallel
parking spaces to the right of
the vehicle up to the sensors’
range of 1.5 m (5 ft). 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 press and hold

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.

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.
Radio Frequency
Information
See Radio Frequency
Statement

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.

350 Driving and Operating
Always signal turns well in
advance. Do not steer or brake
suddenly.
Driving on Grades
Reduce speed and shift to a
lower gear before starting
down a long or steep downhill
grade. If the transmission is
not shifted down, the brakes
may overheat and result in
reduced braking efficiency.
The vehicle can tow in D
(Drive). Shift the transmission
to a lower gear if the
transmission shifts too often
under heavy loads and/or hilly
conditions.
When towing at higher
altitudes, engine coolant will
boil at a lower temperature
than at lower altitudes. If the
engine is turned off
immediately after towing at
high altitude on steep uphill
grades, the vehicle could show
signs similar to engine
overheating. To avoid this, let
the engine run, preferably onlevel ground, with the
transmission in P (Park) for a
few minutes before turning
the engine off. If the overheat
warning comes on, see Engine
Overheating
0381.
Parking on Hills
{Warning
To prevent serious injury or
death, always park your
vehicle and trailer on a level
surface when possible.
When parking your vehicle and
your trailer on a hill: 1. Press the brake pedal, but do not shift into P (Park)
yet. Turn the wheels into
the curb if facing downhill
or into traffic if facing
uphill.
2. Have someone place chocks under the trailer
wheels. 3. When the wheel chocks
are in place, gradually
release the brake pedal to
allow the chocks to absorb
the load of the trailer.
4. Reapply the brake pedal. Then apply the parking
brake and shift into
P (Park).
5. Release the brake pedal.
Leaving After Parking on
a Hill
1. Apply and hold the brake pedal:
.Start the engine.
.Shift into the
desired gear.
.Release the parking
brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the
chocks.
