Driving and Operating 225
Park Assist
If equipped with Rear Park Assist (RPA) and
Front Park Assist (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 the vehicle and
1.2 m (4 ft) in front of the vehicle within a
zone 25 cm (10 in) 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 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 8 km/h (5 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.
The instrument cluster may have a Park
Assist display with bars that show“distance
to object” and object location information
for the Park Assist system. As the object
gets closer, more bars light up and the bars
will change color from yellow, to amber,
to red.
When an object is first detected in the rear,
one beep will sound from the rear. 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. Beeps
for FPA are higher pitched than for RPA.
Turning the Features On or Off
To turn Park Assist on or off, pressXon
the center console. The indicator light next
to the button comes on when the features
are on and turns off when the features have
been disabled.
RPA symbols can be turned on or off
through vehicle personalization. To view a
list of available options from the
infotainment home page, touch Settings >
Vehicle > Collision Detection Systems.
Turn off RPA when towing a trailer.
Automatic Parking Assist (APA)
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.

Buick Encore GX Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
16263917) - 2023 - CRC - 2/24/22
Driving and Operating 227
In case the driver brakes, APA will not
disengage. Manual steering by the driver
automatically disengages APA.
Vehicle speed is limited to a maximum of
5 km/h (3 mph) during the parking
maneuver.
A progress arrow displays the status of the
parking maneuver. Depending on the space
size, additional maneuvers may be required,
and there will be additional instructions.
When changing gears, allow the automatic
steering to complete before continuing the
parking maneuver. APA will beep and
display a PARKING COMPLETE message.
Apply the brakes and place the vehicle in
P (Park).
APA may automatically disengage if:
.The steering wheel is used by the driver.
.The maximum allowed speed is exceeded.
.The parking brake is applied or the
vehicle is shifted into P (Park).
.There is a failure with the APA system.
.Electronic stability control or antilock
brakes are activated.
.A high priority vehicle message is
displayed in the DIC.
.The driver opens the door with an
unbuckled seat belt.The brake holds the vehicle until the parking
brake or brake is applied, or the vehicle is
shifted into P (Park).
To cancel APA, press
Oagain.
When the System Does Not Seem to
Work Properly
The APA system may require a short period
of driving along curves to calibrate.
Rear Cross Traffic Alert (RCTA)
System
If equipped, when the vehicle is shifted into
R (Reverse), 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 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.
Turning the Features On or Off
RCTA can be turned on or off through
vehicle personalization. To view available
settings for this feature, touch the Settings
icon on the infotainment home page. Select
“Vehicle”
to display the list of available
options and select “Collision/Detection
Systems”.
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
If equipped, 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. FCA also lights an amber
visual alert if following another vehicle
much too closely.

16263917) - 2023 - CRC - 2/24/22
230 Driving and Operating
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, this may correct the issue:
.Clean the outside of the windshield in
front of the rearview mirror.
.Clean the entire front of the vehicle.
.Clean the headlamps.
Automatic Emergency
Braking (AEB)
The AEB system may help avoid or reduce
the harm caused by a front-end crashes. AEB
also 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 mayautomatically brake moderately or hard. This
automatic emergency 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
0227.
The system works when driving in a forward
gear between 8 km/h (5 mph) and 80 km/h
(50 mph), or on vehicles with Adaptive
Cruise Control (ACC), above 4 km/h (2 mph).
It can detect vehicles up to approximately
60 m (197 ft).
{Warning
AEB is an emergency crash preparation
feature and is not designed to avoid
crashes. Do not rely on AEB to brake the
vehicle. AEB will not brake outside of its
operating speed range and only responds
to detected vehicles.
AEB may not:
.Detect a vehicle ahead on winding or
hilly roads.
.Detect all vehicles, especially vehicles
with a trailer, tractors, muddy
vehicles, etc. (Continued)
Warning (Continued)
.Detect a vehicle when weather limits
visibility, such as in fog, rain, or snow.
.Detect a vehicle ahead if it is partially
blocked by pedestrians or other
objects.
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.
AEB may slow the vehicle to a complete
stop to try to avoid a potential crash. If this
happens, AEB may hold the vehicle at rest
momentarily. A firm press the accelerator
pedal will release the brake.
{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.

16263917) - 2023 - CRC - 2/24/22
Driving and Operating 231
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. To view available settings
for this feature, touch the Settings icon on
the infotainment home page. Select
“Vehicle” to display the list of available
options and select “Collision/Detection
Systems”.
{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. The indicator
may also be white depending on the equipped instrument cluster. See
Instrument
Cluster 093. When approaching a detected
pedestrian too quickly, FPB provides a red
flashing alert on the windshield and rapidly
beeps. 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)
0 230.
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.
{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. (Continued)

Buick Encore GX Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
16263917) - 2023 - CRC - 2/24/22
Driving and Operating 233
Eight rapid high-pitched beeps will sound
from the front. 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 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. To view available
settings for this feature, touch the Settings
icon on the infotainment home page. Select
“Vehicle” to display the list of available
options and select “Collision/Detection
Systems”.
{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 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.
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

Buick Encore GX Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
16263917) - 2023 - CRC - 2/24/22
Driving and Operating 235
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" underExterior Care0314. 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.
Radio Frequency Information
See
Radio Frequency Statement 0343.
Lane Keep Assist (LKA)
If equipped, LKA may help avoid crashes due
to unintentional lane departures. This
system uses a camera to detect lane
markings. The LKA may be ready to assist at
speeds between 50 km/h (31 mph) and 180
km/h (112 mph). LKA may assist by gently
turning the steering wheel if the vehicle
approaches a detected lane marking. It may
also provide a Lane Departure Warning
(LDW) alert if the vehicle crosses a detected
lane marking. This system is not intended to
keep the vehicle centered in the lane. LKA
will not assist and alert if the turn signal is
active in the direction of lane departure,
or if it detects that you are accelerating,
braking or actively steering. LKA can be overridden by turning the steering wheel.
If the system detects you are steering
intentionally across a lane marker, the LDW
will not be given. Do not expect the LDW to
occur when you are intentionally crossing a
lane marker.
{Warning
The LKA system does not continuously
steer the vehicle. It may not keep the
vehicle in the lane or give a Lane
Departure Warning (LDW) alert, even if a
lane marking is detected.
The LKA and LDW systems may not:
.Provide an alert or enough steering
assist to avoid a lane departure or
crash.
.Detect lane markings under poor
weather or visibility conditions. This
can occur if the windshield or
headlamps are blocked by dirt, snow,
or ice; if they are not in proper
condition; or if the sun shines directly
into the camera.
.Detect road edges.
.Detect lanes on winding or hilly roads.

16263917) - 2023 - CRC - 2/24/22
236 Driving and Operating
Warning (Continued)
If LKA only detects lane markings on one
side of the road, it will only assist or
provide an LDW alert when approaching
the lane on the side where it has
detected a lane marking. Even with LKA
and LDW, you must steer the vehicle.
Always keep your attention on the road
and maintain proper vehicle position
within the lane, or vehicle damage,
injury, or death could occur. Always keep
the windshield, headlamps, and camera
sensors clean and in good repair. Do not
use LKA in bad weather conditions or on
roads with unclear lane markings, such as
construction zones.
{Warning
Using LKA on slippery roads could cause
loss of control of the vehicle and a crash.
Turn the system off.
{Warning
LKA will not alert the driver if a towed
trailer crosses into an adjacent lane of
travel. Serious injury or property damage
may occur if the trailer moves into
another lane. Always monitor the trailer
position while towing to make sure it is
within the same lane as the tow vehicle.
How the System Works
LKA uses a camera sensor installed on the
windshield ahead of the rearview mirror to
detect lane markings. It may provide brief
steering assist if it detects an unintended
lane departure. It may further provide an
audible alert or the driver seat may pulse
indicating that a lane marking has been
crossed. The system does not provide a Lane
Departure Warning (LDW) when
intentionally steering across a lane marker.
To turn LKA on and off, press
Aon the
center console. If equipped, the indicator
light on the button comes on when LKA is
on and turns off when LKA is disabled. On
some vehicles, a long press of over
three seconds is required to turn LKA off. When on,
Ais white, if equipped,
indicating that the system is not ready to
assist.
Ais green if LKA is ready to
assist. LKA may assist by gently turning the
steering wheel if the vehicle approaches a
detected lane marking.
Ais amber when
assisting. It may also provide a Lane
Departure Warning (LDW) alert by flashing
Aamber if the vehicle crosses a
detected lane marking. Additionally, there
may be three beeps, or the driver seat may
pulse three times, on the right or left,
depending on the lane departure direction.
Take Steering
The LKA system does not continuously steer
the vehicle. If LKA does not detect active
driver steering, an alert and chime may be
provided. Steer the vehicle to dismiss. LKA
may become temporarily unavailable after
repeated take steering alerts.
When the System Does Not Seem to
Work Properly
The system performance may be
affected by:
.Close vehicles ahead.
.Sudden lighting changes, such as when
driving through tunnels.

Trailer Towing
General Towing Information
Only use towing equipment that has been
designed for the vehicle. Contact your dealer
or trailering dealer for assistance with
preparing the vehicle to tow a trailer. Read
the entire section before towing a trailer.
To tow a disabled vehicle, seeTransporting
a Disabled Vehicle 0310. To tow the vehicle
behind another vehicle such as a motor
home, see Recreational Vehicle Towing 0311.
Driving Characteristics and
Towing Tips
{Warning
You can lose control when towing a
trailer if the correct equipment is not
used or the vehicle is not driven properly.
For example, if the trailer is too heavy or
the trailer brakes are inadequate for the
load, the vehicle may not stop as
expected. You and others could be
seriously injured. The vehicle may also be
damaged, and the repairs would not be
covered by the vehicle warranty. Pull a
trailer only if all the steps in this section
have been followed. Ask your dealer for
advice and information about towing a
trailer with the vehicle.
Driving with a Trailer
Trailering is different than just driving the
vehicle by itself. Trailering means changes in
handling, acceleration, braking, durability,
and fuel economy. Successful, safe trailering
takes correct equipment, and it has to be
used properly. The following information has many
time-tested, important trailering tips and
safety rules. Many of these are important
for your safety and that of your passengers.
Read this section carefully before pulling a
trailer.
When towing a trailer:
.Become familiar with and follow all state
and local laws that apply to trailer
towing. These requirements vary from
state to state.
.State laws may require the use of
extended side view mirrors. Even if not
required, you should install extended side
view mirrors if your visibility is limited or
restricted while towing.
.Do not tow a trailer during the first
800 km (500 mi) of vehicle use to
prevent damage to the engine, axle,
or other parts.
.It is recommended to perform the first oil
change before heavy towing.
.During the first 800 km (500 mi) of
trailer towing, do not drive over 80 km/h
(50 mph) and do not make starts at full
throttle.
