Automatic Parking Assist (APA)
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

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 the System Does Not Seem to
Work Properly
The APA system may require a short
period of driving along curves to
calibrate.
Assistance Systems for
Driving
If equipped, when driving the vehicle
in a forward gear, Forward Collision
Alert (FCA), Lane Departure Warning
(LDW), Lane Keep Assist (LKA), Side
Blind Zone Alert (SBZA), Lane Change
Alert (LCA), the Forward Automatic
Braking (FAB) system, the 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 pulsesthe 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
0 245.
{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. FCA
does not warn of pedestrians,
animals, signs, guardrails, bridges,
construction barrels, or other
(Continued)
Warning (Continued)
objects. Be ready to take action and
apply the brakes. SeeDefensive
Driving 0207.
FCA can be disabled with either the
FCA steering wheel control or,
if equipped, through vehicle
personalization. See “Collision/
Detection Systems” underVehicle
Personalization 0170.

DRIVING AND OPERATING 267
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.
SeeInstrument Cluster (Base Level)
0 127 orInstrument Cluster (Uplevel)
0 130. 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. 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 much too
quickly, the amber box turns red, and
a red flashing icon,
~, displays on the
HUD with rapid beeping or pulsing of
the Safety Alert Seat, if equipped.
System pedestrian icons, beeps, and
(if equipped) Safety Alert Seat pulses
can be set to Off through vehicle
personalization by turning off the
Front Pedestrian Braking system. See
“Front Pedestrian Detection ”in

system does not need service.
In rain, snow, or fog the image may
not be clear and the direction of the
road ahead may not be seen. In more
severe weather conditions, the image
may be unclear and unusable. The
system does not need service.
Keep the system sensor clean by
activating the windshield washer up to
five times when it is dark enough for
the system to operate. If the Night
Vision image still looks blurry, use a
soft wet cloth to gently clean the
sensor camera lens and dry thoroughly. The sensor is behind the
front grille to the inside of the driver
side headlamp.
The camera must also be aligned to
work correctly. If the camera needs
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 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.

DRIVING AND OPERATING 269
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 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.

Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-11292458) -
2018 - crc - 2/14/17
270 DRIVING AND OPERATING
LCA can be disabled through vehicle
personalization using the Side Blind
Zone Alert option. See“Collision/
Detection Systems” underVehicle
Personalization 0170. 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 Care0380.
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.
When LCA is disabled for any reason
other than the driver turning it off,
the Side Blind Zone Alert On option
will not be available on the
personalization menu.
Radio Frequency Information
See
Radio Frequency Statement 0417.
Lane Departure
Warning (LDW)
If equipped, LDW may help avoid
crashes due to unintentional lane
departures. It may provide a warning
if the vehicle is crossing a detected
lane marking without using a turn
signal in the lane departure direction.
Since this system is part of the Lane
Keep Assist (LKA) system, read the
entire LKA section before using this
feature.
