may be flashing if a vehicle ahead was
present and moved. See“Approaching
and Following a Vehicle ”later in this
section.
Once ACC has resumed, if there is no
vehicle ahead, if the vehicle ahead is
beyond the selected following gap,
or if the vehicle has exited a sharp
curve, then the vehicle speed will
increase to the set speed.
Increasing Speed While ACC is at a
Set Speed
If ACC is already activated, do one of
the following:
.Use the accelerator to get to the
higher speed. Briefly press and
release SET– and release the
accelerator pedal. The vehicle will
now cruise at the higher speed.
When the accelerator pedal is
pressed, ACC will not brake because
it is overridden. While overridden,
the ACC indicator will turn blue on
the instrument cluster and heads up
display, if equipped.
.Press and hold RES+ until the
desired set speed is displayed, then
release it.
.To increase speed in small
increments, press RES+ to the first
detent. For each press, the vehicle
goes 1 km/h (1 mph) faster.
.To increase speed in larger
increments, press RES+ to the
second detent. For each press, the
vehicle speed increases to the next
5 km/h (5 mph) mark on the
speedometer.
The set speed can also be increased
while the vehicle is stopped.
.If stopped with the brake applied,
press RES+ until the desired set
speed is displayed.
.If ACC is holding the vehicle at a
stop and there is another vehicle
directly ahead, pressing RES+ will
increase the set speed.
.Pressing RES+ when there is no
longer a vehicle ahead or the vehicle
ahead is pulling away and the brake
is not applied will cause the ACC to
resume.
When it is determined that there is no
vehicle ahead or the vehicle ahead is
beyond the selected following gap,
then the vehicle speed will increase to
the set speed. The speedometer reading can be
displayed in either English or metric
units. See
Instrument Cluster 099. The
increment value used depends on the
units displayed.
Reducing Speed While ACC is at a
Set Speed
If ACC is already activated, do one of
the following:
.Use the brake to get to the desired
lower speed. Release the brake and
press SET– . The vehicle will now
cruise at the lower speed.
.Press and hold SET– until the
desired lower speed is reached, then
release it.
.To decrease speed in smaller
increments, press SET− to the first
detent. For each press, the vehicle
goes about 1 km/h (1 mph) slower.
.To decrease speed in larger
increments, press SET− to the
second detent. For each press, the
vehicle speed decreases to the next
5 km/h (5 mph) mark on the
speedometer.
The set speed can also be decreased
while the vehicle is stopped.

.If stopped with the brake applied,
press or hold SET−until the desired
set speed is displayed.
The speedometer reading can be
displayed in either English or metric
units. See Instrument Cluster 099. The
increment value used depends on the
units displayed.
Selecting the Follow Distance Gap
When a slower moving vehicle is
detected ahead within the selected
following gap, ACC will adjust the
vehicle's speed and attempt to
maintain the follow distance gap
selected.
Press
[on the steering wheel to
adjust the following gap. Each press
cycles the gap button through three
settings: Far, Medium, or Near.
When pressed, the current gap setting
displays briefly on the instrument
cluster and HUD, if equipped. The gap
setting will be maintained until it is
changed.
Since each gap setting corresponds to
a following time (Far, Medium,
or Near), the following distance will
vary based on vehicle speed. The faster the vehicle speed, the further
back your vehicle will follow a vehicle
detected ahead. Consider traffic and
weather conditions when selecting the
following gap. The range of selectable
gaps may not be appropriate for all
drivers and driving conditions.
Changing the gap setting
automatically changes the alert timing
sensitivity (Far, Medium, or Near) for
the Forward Collision Alert (FCA)
feature. See
Forward Collision Alert
(FCA) System 0258.
Alerting the Driver
With Head-Up Display
Without Head-Up Display 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, six red
lights or the collision alert symbol on
the HUD, if equipped, 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 0206.
Approaching and Following a
Vehicle
The vehicle ahead indicator is in the
instrument cluster and HUD display,
if equipped.

Cadillac XT4 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
14584367) - 2021 - CRC - 10/14/20
DRIVING AND OPERATING 245
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 for
vehicles ahead.
ACC automatically slows the vehicle
down and adjusts vehicle speed to
follow the vehicle in front at the
selected follow gap. The vehicle speed
increases or decreases to follow the
vehicle in front of you, but will not
exceed the 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.
Stationary or Very Slow-Moving
Objects
{Warning
ACC may not detect and react to
stopped or slow-moving vehicles
ahead of you. For example, the
system may not brake for a vehicle
it has never detected moving. This
can occur in stop-and-go traffic or
when a vehicle suddenly appears
due to a vehicle ahead changing
lanes. Your vehicle may not stop
and could cause a crash. Use (Continued)
Warning (Continued)
caution when using ACC. Your
complete attention is always
required while driving and you
should be ready to take action and
apply the brakes.
ACC Automatically Disengages
ACC may automatically disengage and
the driver will need to manually apply
the brakes to slow the vehicle when:
.The sensors are blocked.
.The Traction Control System (TCS)
or StabiliTrak/ESC system has
activated or been disabled.
.There is a fault in the system.
.The radar falsely reports blockage
when driving in a desert or remote
area with no other vehicles or
roadside objects. A DIC message
may display to indicate that ACC is
temporarily unavailable.
The ACC indicator will turn white
when ACC is no longer active.
In some cases, when ACC is
temporarily unavailable, regular cruise
control may be used. See “Switching

246 DRIVING AND OPERATING
Between ACC and Regular Cruise
Control”in this section. Always
consider driving conditions before
using either cruise control system.
Notification to Resume ACC
ACC will maintain a follow gap behind
a detected vehicle and slow your
vehicle to a stop behind that vehicle.
If the stopped vehicle ahead has
driven away and ACC has not
resumed, the vehicle ahead indicator
will flash as a reminder to check
traffic ahead before proceeding. In
addition, the left and right sides of the
Safety Alert Seat will pulse three
times, or three beeps will sound. See
”Alert Type ”and “Adaptive Cruise Go
Notifier” in“Collision/Detection
Systems” underVehicle Personalization
0 120.
When the vehicle ahead drives away,
ACC resumes automatically if the stop
was brief. If necessary, press RES+ or
the accelerator pedal to resume ACC.
If stopped for more than two minutes
or if the driver door is opened and the
driver seat belt is unbuckled, the ACC
automatically applies the Electric
Parking Brake (EPB) to hold the vehicle. The EPB status light will turn
on. See
Electric Parking Brake 0233.
To release the EPB, press the
accelerator pedal.
A DIC warning message may display
indicating to shift to P (Park) before
exiting the vehicle. See Vehicle
Messages 0119.
{Warning
If ACC has stopped the vehicle, and
if ACC is disengaged, turned off,
or canceled, the vehicle will no
longer be held at a stop. The vehicle
can move. When ACC is holding the
vehicle at a stop, always be
prepared to manually apply the
brakes.
{Warning
Leaving the vehicle without placing
it in P (Park) can be dangerous. Do
not leave the vehicle while it is
being held at a stop by ACC. Always
place the vehicle in P (Park) and
turn off the ignition before leaving
the vehicle. ACC Override
If using the accelerator pedal while
ACC is active, the ACC indicator turns
blue on the instrument cluster and in
the HUD (if equipped) to indicate that
automatic braking will not occur. ACC
will resume operation when the
accelerator pedal is not being pressed.
{Warning
The ACC will not automatically
apply the brakes if your foot is
resting on the accelerator pedal.
You could crash into a vehicle
ahead of you.
Curves in the Road
{Warning
On curves, ACC may not detect a
vehicle ahead in your lane. You
could be startled if the vehicle
accelerates up to the set speed,
especially when following a vehicle
exiting or entering exit ramps. You
could lose control of the vehicle or
crash. Do not use ACC while driving (Continued)
