The cruise control system may
automatically brake to slow
the vehicle down.
The speedometer reading can
be displayed in either English
or metric units. See
Instrument Cluster0119. The
increment value used depends
on the units displayed.
Passing Another Vehicle
While Using Cruise Control
Use the accelerator pedal to
increase the vehicle speed.
When you take your foot off
the pedal, the vehicle will slow
down to the previous set
cruise speed.
While pressing the accelerator
pedal or shortly following the
release to override cruise,
briefly moving the thumbwheel
down toward SET− will result
in cruise set to the current
vehicle speed.
Using Cruise Control on Hills
How well the cruise control will
work on hills depends upon
the vehicle speed, load, and the steepness of the hills.
When going up steep hills, you
might have to step on the
accelerator pedal to maintain
your speed. When going
downhill, the cruise control
system may automatically
brake to slow the vehicle
down. Also, you may have to
brake or shift to a lower gear
to keep your speed down.
If the brake pedal is applied,
cruise control disengages.
Ending Cruise Control
There are four ways to end
cruise control:
.Step lightly on the brake
pedal.
.Press*.
.Shift the transmission to
N (Neutral).
.PressJ.
Erasing Speed Memory
The cruise control set speed is
erased from memory if
Jis
pressed or if the ignition is
turned off.
Adaptive Cruise
Control (Advanced)
If equipped with Adaptive
Cruise Control (ACC), it allows
the driver to select the cruise
control set speed and
following gap. Read this entire
section before using this
system. The following gap is
the following time between
your vehicle and a vehicle
detected directly ahead in
your path, moving in the same
direction. If no vehicle is
detected in your path, ACC
works like regular cruise
control. ACC uses camera and
radar sensors. See Radio
Frequency Statement 0446.
If a vehicle is detected in your
path, ACC can apply
acceleration or limited,
moderate braking to maintain
the selected following gap. To
disengage ACC, apply the
brake. If ACC is controlling
your vehicle speed when the
Traction Control System (TCS)
or StabiliTrak/Electronic

Cadillac XT4 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
16412876) - 2023 - CRC - 3/25/22
274 Driving and Operating
Stability Control (ESC) system
activates, the ACC may
automatically disengage. See
Traction Control/Electronic
Stability Control0267. When
road conditions allow ACC to
be safely used, the ACC can
be turned back on.
Disabling the TCS or
StabiliTrak/ESC system will
disengage and prevent
engagement of ACC.
ACC can reduce the need for
you to frequently brake and
accelerate, especially when
used on expressways,
freeways, and interstate
highways. When used on other
roads, you may need to take
over the control of braking or
acceleration more often.
ACC automatically slows the
vehicle down while navigating
the curve and may increase
speed out of the curve, but will
not exceed the set speed.{Warning
ACC has limited braking
ability and may not have
time to slow the vehicle
down enough to avoid a
collision with another vehicle
you are following. This can
occur when vehicles
suddenly slow or stop
ahead, or enter your lane.
Also see “Alerting the
Driver” in this section.
Complete attention is
always required while driving
and you should be ready to
take action and apply the
brakes. See Defensive
Driving 0230.
{Warning
ACC will not detect or brake
for children, pedestrians,
animals, or other objects.
Do not use ACC when:
.On winding and hilly roads
or when the sensors are
blocked by snow, ice,
or dirt. The system may
not detect a vehicle
ahead. Keep the entire
front of the vehicle clean.
.Visibility is low, such as in
fog, rain, or snow
conditions. ACC
performance is limited
under these conditions.
.On slippery roads where
fast changes in tire
traction can cause
excessive wheel slip.
.When towing a trailer.

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 caution
when using ACC. Your
complete attention is always (Continued)
Warning (Continued)
required while driving and
you should be ready to take
action and apply the brakes.
Irregular Objects
Affecting ACC
ACC may have difficulty
detecting the following
objects:
.Vehicles with cargo
extending from the back end.
.Non-standard shaped
vehicles, such as vehicle
transport, vehicles with a
side car fitted, or horse
carriages.
.Objects that are close to the
front of your vehicle.
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 Between
ACC and Regular Cruise
Control” in this section. Always
consider driving conditions
before using either cruise
control system.

Sensors located in the
bumpers measure the
distance between the vehicle
and objects using sonar
technology. These sensors are
designed to detect certain
objects up to 2.5 m (8 ft)

Cadillac XT4 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
16412876) - 2023 - CRC - 3/25/22
290 Driving and Operating
behind and 1.2 m (4 ft) in front
of your vehicle that are taller
than 25 cm (10 in).
Different environmental
conditions may affect whether
and how far the Park Assist
system can detect objects.
Keep the sensors clean of
mud, dirt, snow, ice, and slush;
and clean sensors after a car
wash in freezing
temperatures. Sensors that
are not clean may not detect
objects or may cause the
system to alert when not
required.
{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(Continued)
Warning (Continued)
than 9 km/h (6 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 vehicle may have a Park
Assist amphitheatre-like
display on the cluster with
bars that represent the
estimated location of a
detected object and the
vehicle’s distance from the
object. As a detected object
becomes closer, more bars
light up and 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 the driver's seat will pulse
two times, if equipped with
Safety Alert Seat. When an
object is very close, five beeps will sound from the front or
rear (depending on the
object's location), or the
driver's seat will pulse five
times. Beeps for front are
higher pitched than the rear.
Turning the System On

clean. Keep the vehicle's
front and rear bumpers free
of mud, dirt, snow, ice, and
slush. For cleaning
instructions, see Exterior
Care 0412.
.The Park Assist sensors may
be 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 a service message displays
and the above conditions do
not exist, take the vehicle to
your dealer for repairs.
If the Park Assist System does
not activate due to a
temporary condition, a system
off message is shown on the
display. This can occur under
the following conditions:
.The driver has disabled the
system.
.An object is currently
blocking the rear sensors
(for example, bike rack,
tailgate, trailer hitch, etc.).
Once the object is removed,
Park Assist will return to
normal operation.
.The bumper is damaged.
Take the vehicle to your
dealer for repairs.
.Other conditions, such as
vibrations from a
jackhammer or the
compression of air brakes on
a very large truck, are
affecting system
performance.
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
