256 DRIVING AND OPERATING
Parking Assist
With RPA, and if equipped with FPA,
as the vehicle moves at speeds of less
than 8 km/h (5 mph) the sensors on
the bumpers may detect objects up to
2.5 m (8 ft) behind and 1.2 m (4 ft) in
front of the vehicle within a zone
25 cm (10 in) high off the ground and
below bumper level. These detection
distances may be shorter during
warmer or humid weather. Blocked
sensors will not detect objects and
can also cause false detections. Keep
the sensors clean of mud, dirt, snow,
ice, and slush; and clean sensors after
a car wash in freezing temperatures.
{Warning
The Parking Assist system does not
detect children, pedestrians,
bicyclists, animals, or objects
located below the bumper or that
are too close or too far from the
vehicle. It is not available at speeds
greater than 8 km/h (5 mph). To
prevent injury, death, or vehicle
damage, even with Parking Assist,(Continued)
Warning (Continued)
always check the area around the
vehicle and check all mirrors before
moving forward or backing.
The instrument cluster may have a
parking assist display with bars that
show“distance to object ”and object
location information for the Parking
Assist system. As the object gets
closer, more bars light up and the bars
change color from yellow to amber
to red.
When an object is first detected in the
rear, one beep will be heard from the
rear, or both sides of the Safety Alert
Seat will pulse two times. When an
object is very close (<0.6 m (2 ft) in the vehicle rear, or <0.3 m (1 ft) in the
vehicle front), five beeps will sound
from the front or rear depending on
object location, or both sides of the
Safety Alert Seat will pulse five times.
Beeps for FPA are higher pitched than
for RPA.
Backing Warning and Reverse
Automatic Braking
Vehicles with Adaptive Cruise Control
(ACC) have the Backing Warning
System and Reverse Automatic
Braking (RAB) system. The Backing
Warning part of this system can warn
of rear objects when backing up at
speeds greater than 8 km/h (5 mph).
The Backing Warning System will
beep once from the rear when an
object is first detected, or pulse twice
on both sides of the Safety Alert Seat.
When the system detects a potential
crash, beeps will be heard from the
rear, or five pulses will be felt on both
sides of the Safety Alert Seat. There
may also be a brief, sharp application
of the brakes.

DRIVING AND OPERATING 261
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
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. Tailgating AlertThe vehicle ahead indicator will
display amber when you are following
a vehicle ahead much too closely.

262 DRIVING AND OPERATING
Selecting the Alert Timing
The Collision Alert control is on the
steering wheel. Press
[to set the
FCA timing to Far, Medium, or Near,
or on some vehicles, Off. The first
button press shows the current setting
on the DIC. Additional button presses
will change this setting. The chosen
setting will remain until it is changed
and will affect the timing of both the
Collision Alert and the Tailgating
Alert features. The timing of both
alerts will vary based on vehicle speed.
The faster the vehicle speed, the
farther away the alert will occur.
Consider traffic and weather
conditions when selecting the alert timing. The range of selectable alert
timings may not be appropriate for all
drivers and driving conditions.
If your vehicle is equipped with
Adaptive Cruise Control (ACC),
changing the FCA timing setting
automatically changes the following
gap setting (Far, Medium, or Near).
Following Distance Indicator
The following distance to a moving
vehicle ahead in your path is indicated
in following time in seconds on the
Driver Information Center (DIC). See
Driver Information Center (DIC)
0162.
The minimum following time is
0.5 seconds away. If there is no vehicle
detected ahead, or the vehicle ahead is
out of sensor range, dashes will be
displayed.
Unnecessary Alerts
FCA may provide unnecessary alerts
for turning vehicles, vehicles in other
lanes, objects that are not vehicles,
or shadows. These alerts are normal
operation and the vehicle does not
need service.
Cleaning the System
If the FCA system does not seem to
operate properly, cleaning the outside
of the windshield in front of the
rearview mirror, and cleaning the
front of the vehicle where radar
sensors are located, may correct the
issue.
Forward Automatic
Braking (FAB)
If the vehicle has Forward Collision
Alert (FCA), it also has FAB, 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 forward automatic 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 0260.

Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-11292458) -

264 DRIVING AND OPERATING
FAB and IBA can be disabled through
vehicle personalization. See“Collision/
Detection Systems” underVehicle
Personalization 0170.
{Warning
Using FAB 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 system.
The FAB 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 directly 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
Forward Automatic Braking (FAB)
System may also respond to
pedestrians. See Forward Automatic
Braking (FAB) 0262.
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. If the vehicle is
equipped with the Night Vision
system, during nighttime driving, the
vehicle can detect and alert to
pedestrians whenever in a
forward gear.{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,
seeDefensive Driving 0207. Keep
the windshield, headlamps, and FPB
sensor clean and in good repair.
FPB can be set to Off, Alert, or Alert &
Brake through vehicle personalization.
See “Front Pedestrian Detection ”in
“Collision/Detection Systems” under
Vehicle Personalization 0170.
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 directly 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 directly 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 also
equipped with the Night Vision
system, pedestrians detected by the
Night Vision system will not cause
automatic braking to occur.
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.

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) -

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.
