EPB Release
To release the EPB:1. Turn the ignition on or to ACC/ ACCESSORY.
2. Apply and hold the brake pedal.
3. Press the EPB switch momentarily.
The EPB is released when the red
parking brake status light is off.
If the amber service parking brake
warning light is on, release the EPB by
pressing and holding the EPB switch.
Continue to hold the switch until the
red parking brake status light is off.
If either light stays on after release is
attempted, see your dealer.
Caution
Driving with the parking brake on
can overheat the brake system and
cause premature wear or damage to
brake system parts. Make sure that
the parking brake is fully released
and the brake warning light is off
before driving.
If you are towing a trailer and parking
on a hill, see Driving Characteristics
and Towing Tips 0271.
Automatic EPB Release
The EPB will automatically release if
the vehicle is running, placed into
gear, and an attempt is made to drive
away. Avoid rapid acceleration when
the EPB is applied, to preserve parking
brake lining life.
Brake Assist
Brake Assist detects rapid brake pedal
applications due to emergency braking
situations and provides additional
braking to activate the Antilock Brake
System (ABS) if the brake pedal is not
pushed hard enough to activate ABS
normally. Minor noise, brake pedal
pulsation, and/or pedal movement
during this time may occur. Continue
to apply the brake pedal as the driving
situation dictates. Brake Assist
disengages when the brake pedal is
released.
Hill Start Assist (HSA)
{Warning
Do not rely on the HSA feature.
HSA does not replace the need to
pay attention and drive safely. You
may not hear or feel alerts or
warnings provided by this system.
Failure to use proper care when
driving may result in injury, death,
or vehicle damage. See Defensive
Driving 0206.
When the vehicle is stopped on a
grade, Hill Start Assist (HSA) prevents
the vehicle from rolling in an
unintended direction during the
transition from brake pedal release to
accelerator pedal apply. The brakes
release when the accelerator pedal is
applied. If the accelerator pedal is not
applied within a few minutes, the
Electric Parking Brake will apply. The
brakes may also release under other
conditions. Do not rely on HSA to
hold the vehicle.
HSA is available when the vehicle is
facing uphill in a forward gear,
or when facing downhill in

248 DRIVING AND OPERATING
Do Not Use ACC on Hills and When
Towing a Trailer
Do not use ACC when driving on steep
hills or when towing a trailer. ACC will
not detect a vehicle in the lane while
driving on steep hills. The driver will
often need to take over acceleration
and braking on steep hills, especially
when towing a trailer. If the brakes are
applied, the ACC disengages.
Disengaging ACC
There are three ways to
disengage ACC:
.Step lightly on the brake pedal.
.Press*.
.PressJ.Erasing Speed Memory
The cruise control set speed is erased
from memory if
Jis pressed or if the
ignition is turned off.
Cleaning the Sensing System
The camera sensor on the windshield
behind the rearview mirror and the
radar sensors on the front of the
vehicle can become blocked by snow,
ice, dirt, or mud. These areas need to
be cleaned for ACC to operate
properly.
For cleaning instructions, see
“Washing the Vehicle ”under Exterior
Care 0348.
System operation may also be limited
under snow, heavy rain, or road spray
conditions.
Driver Assistance
Systems
This vehicle may have features that
work together to help avoid crashes or
reduce crash damage while driving,
backing, and parking. Read this entire
section before using these systems.
{Warning
Do not rely on the Driver
Assistance Systems. These systems
do not replace the need for paying
attention and driving safely. You
may not hear or feel alerts or
warnings provided by these
systems. Failure to use proper care
when driving may result in injury,
death, or vehicle damage. See
Defensive Driving 0206.
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. (Continued)

system to occur. To prevent injury,
death, or vehicle damage, even with
the Backing Warning System,
always check the area around the
vehicle and check all mirrors before
backing.
When the vehicle is in R (Reverse),
if the system detects the vehicle is
backing too fast to avoid a crash with
a detected object behind your vehicle
in your path, it may automatically
brake hard to a stop to help avoid or
reduce the harm caused by a backing
crash.
{Warning
RAB may not avoid many types of
backing crashes. Do not wait for the
automatic braking to apply. This
system is not designed to replace
driver braking and only works in
R (Reverse) when an object is
detected directly behind the vehicle.
It may not brake or stop in time to
avoid a crash. It will not brake for (Continued)
Warning (Continued)
objects when the vehicle is moving
at very low speeds. It does not
detect children, pedestrians,
bicyclists, animals, or objects below
the bumper or that are too close or
too far from the vehicle. To prevent
injury, death, or vehicle damage,
even with RAB, always check the
area around the vehicle before and
while backing.
Pressing the brake pedal after the
vehicle comes to a stop will release
RAB. If the brake pedal is not pressed
soon after the stop, the Electric
Parking Brake (EPB) may be set. When
it is safe, press the accelerator pedal
firmly at any time to override RAB.
{Warning
There may be instances where
unexpected or undesired automatic
braking occurs. If this happens,
either press the brake pedal or
firmly press the accelerator pedal to
release the brakes from the RAB (Continued)
Warning (Continued)
system. Before releasing the brakes,
check the RVC and check the area
around the vehicle to make sure it
is safe to proceed.
Rear Cross Traffic Alert (RCTA)
If equipped, RCTA displays a red
warning triangle with a left or right
pointing arrow on the infotainment
display to warn of traffic coming from
the left or right. This system detects
objects coming from up to 20 m (65 ft)
from the left or right side of the
vehicle. When an object is detected,
either three beeps sound from the left
or right or three Safety Alert Seat
pulses occur on the left or right side,
depending on the direction of the
detected vehicle.
Use caution while backing up when
towing a trailer, as the RCTA
detection zones that extend out from
the back of the vehicle do not move
further back when a trailer is towed.
See Radio Frequency Statement 0383.

Automatic Parking Assist (APA)
with Braking
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.
Press
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.
.Park without having at least one
vehicle in an adjacent parking spot.
When enabled, APA searches for
parallel parking spaces to the right of
the vehicle. To search for a parking
space to the left, turn on the left turn
signal or, if available, change the side
selection in the infotainment display.
To switch the parking mode between
parallel and perpendicular, press and
hold

DRIVING AND OPERATING 261
{Warning
AEB may automatically brake the
vehicle suddenly in situations
where it is unexpected and
undesired. It could respond to a
turning vehicle ahead, guardrails,
signs, and other non-moving
objects. To override AEB, firmly
press the accelerator pedal, if it is
safe to do so.
Intelligent Brake Assist (IBA)
IBA may activate when the brake
pedal is applied quickly by providing a
boost to braking based on the speed
of approach and distance to a vehicle
ahead.
Minor brake pedal pulsations or pedal
movement during this time is normal
and the brake pedal should continue
to be applied as needed. IBA will
automatically disengage only when
the brake pedal is released.
{Warning
IBA may increase vehicle braking in
situations when it may not be
necessary. You could block the flow
of traffic. If this occurs, take your
foot off the brake pedal and then
apply the brakes as needed.
AEB and IBA can be disabled through
vehicle personalization. See “Collision/
Detection Systems” underVehicle
Personalization 0120.
{Warning
Using AEB 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/Electronic Stability
Control (ESC) system.
The AEB 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 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 Automatic Emergency Braking
(AEB) system may also respond to
pedestrians. See Automatic Emergency
Braking (AEB) 0260.
The FPB system can detect and alert
to pedestrians in a forward gear at
speeds between 8 km/h (5 mph) and

Cadillac XT4 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
14584367) - 2021 - CRC - 10/14/20
DRIVING AND OPERATING 263
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 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.
{Warning
FPB may alert or automatically
brake the vehicle suddenly in
situations where it is unexpected
and undesired. It could falsely alert
or brake for objects similar in shape
or size to pedestrians, including
shadows. This is normal operation
and the vehicle does not need
service. To override Automatic
Braking, firmly press the accelerator
pedal, if it is safe to do so.
Automatic Braking can be disabled
through vehicle personalization. See
“Front Pedestrian Detection ”in
“Collision/Detection Systems” under
Vehicle Personalization 0120.
{Warning
Using the Front Pedestrian Braking
system while towing a trailer could
cause you to lose control of the
vehicle and crash. Turn the system
to Alert or Off when towing a
trailer.
Cleaning the System
If FPB does not seem to operate
properly, cleaning the outside of the
windshield in front of the rearview
mirror may correct the issue.
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 blind 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.
