274 DRIVING AND OPERATING
Alerting the Driver
If ACC is engaged, driver action may
be required when ACC cannot apply
sufficient braking because of
approaching a vehicle too rapidly.
When this condition occurs, the
collision alert symbol will flash on the
windshield. Either eight beeps will
sound from the front, or both sides of
the Safety Alert Seat will pulse five
times. See“Collision/Detection
Systems” underVehicle Personalization
0 120.
See Defensive Driving 0210. Approaching and Following a
VehicleThe vehicle ahead indicator is in the
instrument cluster and HUD display,
if equipped.
The vehicle ahead indicator only
displays when a vehicle is detected in
your vehicle’s path moving in the
same direction.
If this symbol is not displaying, ACC
will not respond to or brake to
vehicles ahead.
ACC automatically slows the vehicle
down and adjusts vehicle speed to
follow a detected vehicle ahead at the
selected follow gap. The vehicle speed
increases or decreases to follow a
detected vehicle in front of your
vehicle when that vehicle is traveling
slower than your vehicle set speed.
It may apply limited braking,
if necessary. When braking is active, the brake lamps will come on. The
automatic braking may feel or sound
different than if the brakes were
applied manually. This is normal.
Passing a Vehicle While Using ACC
If the set speed is high enough, and
the left turn signal is used to pass a
vehicle ahead in the selected following
gap, ACC may assist by gradually
accelerating the vehicle prior to the
lane change.
{Warning
When using ACC to pass a vehicle
or perform a lane change, the
following distance to the vehicle
being passed may be reduced. ACC
may not apply sufficient
acceleration or braking when
passing a vehicle or performing a
lane change. Always be ready to
manually accelerate or brake to
complete the pass or lane change.

DRIVING AND OPERATING 279
Warning (Continued)
.Not a crash avoidance or warning
system
.Not a substitute for proper
supervision of the driving task.
Super Cruise uses the following to
detect the current lane position and
lane markings ahead on compatible
roads under certain conditions:
.Cameras
.Global Positioning System (GPS)
sensing
.A high-precision map
.GPS-enhancement data downloaded
through Connected Services
Super Cruise works with Adaptive
Cruise Control (ACC), which controls

section and the ACC section before
using Super Cruise. See Adaptive
Cruise Control (Advanced) 0269.
An active Connected Service plan that
includes Super Cruise Services is
required to use Super Cruise.
{Warning
Super Cruise does not perform all
aspects of driving, nor does it do
everything a driver can do. Super
Cruise only steers to maintain
vehicle position in the current lane
or, under some circumstances, to
change lanes. Super Cruise can only
be used with Adaptive Cruise
Control.
Super Cruise does:
.Not prevent crashes or warn of
possible crashes.
.Not steer to avoid stopped or
slow-moving vehicles,
cross-traffic, construction
barriers or cones, motorcycles,
children, pedestrians, animals,
or other objects on the road.
.Not steer in response to vehicles
or objects next to your vehicle,
including vehicles attempting to
enter your lane.
.Not respond to traffic lights, stop
signs, or other traffic control
devices. (Continued)

282 DRIVING AND OPERATING
When engaged and not steering the
vehicle, the steering wheel light bar
flashes blue, and
^will be blue. The
driver is in control of steering and
Super Cruise is not steering the
vehicle.
When the vehicle is positioned in the
center of the lane, the steering wheel
light bar and
^display will turn
green, indicating Super Cruise is
steering the vehicle.
When Super Cruise controls the
steering, traffic and other conditions
and laws permit, and it is safe to do
so, your hands can be taken off the
steering wheel.
Always pay attention to the road and
the operation of the vehicle. Always
monitor and be attentive of
surrounding traffic, including vehicles
that may cross the road in front of
your vehicle.
Super Cruise steering can be
overridden with manual steering at
any time. When Super Cruise is
engaged, always be prepared to take immediate action
—including
steering, accelerating, and braking
quickly, if necessary.
When Super Cruise is engaged, the
Forward Collision System will alert
and brake.
Steering Manually and Changing
Lanes
The vehicle can always be manually
steered, even with Super Cruise
engaged; for example, when manually
changing lanes.
When the steering wheel is moved
manually, the steering wheel light bar
flashes blue and
^on the
instrument cluster turns blue to
indicate Super Cruise is not steering
the vehicle.
When ready to allow Super Cruise to
resume steering again, position the
vehicle in the center of the lane, hold
the steering wheel until the steering
wheel light bar turns green, and then
release the steering wheel when it is
safe to do so. Super Cruise does not respond to
vehicles in other lanes near your
vehicle.
{Warning
To help prevent crashes before
making a lane change:
.Always check mirrors.
.Glance over your shoulder.
.Use the turn signals.
Super Cruise Lane Change
If Super Cruise detects that traffic is
clear, Super Cruise will steer the
vehicle to perform the lane change.
A message appears on the Driver
Information Center (DIC) during the
lane change to provide more
information on the status of the lane
change.
The Super Cruise Automatic Lane
Change feature can be enabled or
disabled through the vehicle
personalization menu. See “Super
Cruise Lane Change ”under Vehicle
Personalization 0120.

284 DRIVING AND OPERATING
To begin steering manually, hold the
steering wheel firmly (with both
hands) using the highlighted regions
as shown in the picture below.
Any time the steering wheel light bar
flashes red, resume manual steering
immediately. The instrument cluster
light
^, will also turn red and a
message will display in the Driver
Information Center (DIC). In addition,
beeps will sound, or the Safety Alert
Seat will vibrate. See “Collision/
Detection Systems” underVehicle
Personalization 0120. After you begin
steering manually, Super Cruise will
disengage. The red flashing steering wheel light
bar could occur under any of the
following conditions:
.Lane markings are poor, or visibility
is limited.
.The Driver Attention System (DAS)
does not detect that the driver's
head and eyes are directed toward
the road.
.ACC is canceled.
.The vehicle is on a tight curve,
or the lanes are too wide, or the
vehicle goes into a curve too fast.
.The compatible road ends.
.The vehicle is approaching an
intersection controlled by a traffic
light, stop sign, or other traffic
control device.
.A Super Cruise system fault occurs.
.Super Cruise is unable to complete
the lane change maneuver.
Attention to the Road
{Warning
Super Cruise is a driver assistance
system and cannot accurately
detect or predict all situations.
Super Cruise is not a crash
avoidance system. To prevent
serious injury or death, you must
supervise the driving task and
monitor the road conditions. You
may need to respond to traffic
events by steering, braking,
or accelerating. See
Defensive
Driving 0210. Super Cruise also
cannot determine whether you are
awake, asleep, impaired, or properly
focused on safe driving. The vehicle
could crash into other vehicles,
drive out of the lane, or drive off
the road. Complete attention is
always required while driving, even
while using Super Cruise. Be
prepared to take over steering or
apply the brakes at any time.

294 DRIVING AND OPERATING
Warning (Continued)
when driving may result in injury,
death, or vehicle damage. See
Defensive Driving0210.
Under many conditions, these
systems will not:
.Detect children, pedestrians,
bicyclists, or animals.
.Detect vehicles or objects outside
the area monitored by the
system.
.Work at all driving speeds.
.Warn you or provide you with
enough time to avoid a crash.
.Work under poor visibility or bad
weather conditions.
.Work if the detection sensor is
not cleaned or is covered by ice,
snow, mud, or dirt.
.Work if the detection sensor is
covered up, such as with a
sticker, magnet, or metal plate. (Continued)
Warning (Continued)
.Work if the detection sensor
viewing zone is interrupted by an
installed accessory, such as a
bike rack, or hitch mounted
cargo carrier.
.Work if the area surrounding the
detection sensor is damaged or
not properly repaired.
Complete attention is always
required while driving, and you
should be ready to take action and
apply the brakes and/or steer the
vehicle to avoid crashes.
Audible or Safety Alert Seat
Some driver assistance features alert
the driver of obstacles by beeping. To
change the volume of the warning
chime, see “Comfort and Convenience ”
under Vehicle Personalization 0120.
If equipped with the Safety Alert Seat,
the driver seat cushion may provide a
vibrating pulse alert instead of
beeping. To change this, see
“Collision/Detection Systems” under
Vehicle Personalization 0120. Cleaning
Depending on vehicle options, keep
these areas of the vehicle clean to
ensure the best driver assistance
feature performance. Driver
Information Center (DIC) messages
may display when the systems are
unavailable or blocked.

Cadillac CT4 Owner Manual (GMNA-Localizing-U.S./Canada-15283641) -
2022 - CRC - 10/12/21
298 DRIVING AND OPERATING
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 Park Assist System is no
substitute for careful and attentive
driving. The Park 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
11 km/h (7 mph). To prevent injury,
death, or vehicle damage, even with
Park Assist, always check the area
around the vehicle and check all
mirrors before moving forward or
backing.
How the System Works
The instrument cluster may have a
Park Assist display with bars that
show“distance to object,” driving
direction, and object location
information for the Park 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 very close to the
vehicle rear (<0.6m (2 ft)), five beeps
will sound from the rear followed by a
continuous beep from the rear,
or both sides of the Safety Alert Seat
will pulse five times. When an object
is very close to the vehicle front
(<0.3m (1 ft)), a continuous beep will
sound from the front, or both sides of the Safety Alert Seat will pulse five
times. Beeps for FPA are higher
pitched than for RPA.
When the System Does Not Seem to
Work Properly
The following messages may be
displayed on the DIC:
SERVICE PARKING ASSIST :
If this
message occurs, check the following
conditions:
.The sensors are not clean. Keep the
vehicle's rear bumper free of mud,
dirt, snow, ice, and slush. For
cleaning instructions, see Exterior
Care 0397.
.The Park Assist sensors are covered
by frost or ice. Frost or ice can form
around and behind the sensors and
may not always be seen; this can
occur after washing the vehicle in
cold weather. The message may not
clear until the frost or ice has
melted.
If the above conditions do not exist,
take the vehicle to your dealer to
repair the system.

Turning the Feature On or Off
Turn off RCTA when towing a trailer.
RCTA can also be turned on or off
through vehicle personalization. See
“Collision/Detection Systems”under
Vehicle Personalization 0120.
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), Automatic Emergency
Braking (AEB), and/or the Front
Pedestrian Braking (FPB) System can
help to avoid a crash or reduce crash
damage.
Forward Collision Alert
(FCA) System
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 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) 0269.
{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 0210.
FCA can be disabled through vehicle
personalization. See "Collision/
Detection Systems" under Vehicle
Personalization 0120.
Detecting the Vehicle Ahead
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.
