Alerting the Driver
Without Head-Up Display
With Head-Up Display Screen Closed
With Head-Up Display Screen Open
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 red collision
alert symbol will flash on the windshield or
on the HUD, if equipped. Eight beeps will
sound from the front.
See Defensive Driving 0191.
Approaching and Following a Vehicle
The vehicle ahead indicator is in the
instrument cluster and HUD display
(If equipped). It 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 a
detected vehicle ahead at the selected
following 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

Warning (Continued)
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
caution when using ACC. Your complete
attention is always 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 in front of your vehicle that have
a rear aspect that is low, small,
or irregular
.An empty truck or trailer that has no
cargo in the cargo bed
.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
.Vehicles that are low to the road surface
.Objects that are close to the front of your
vehicle
.Vehicles on which extremely heavy cargo
is loaded in the cargo area or rear seat
ACC Automatically Disengages
ACC may automatically disengage and the
driver will need to manually apply the
brakes to slow the vehicle if:
.The front camera is blocked or visibility is
reduced.
.The Traction Control System (TCS) or
StabiliTrak/ESC system has activated or
been disabled.
.There is a fault in the system.
.A DIC message displays 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.
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

Buick Encore GX Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
15481080) - 2022 - CRC - 6/1/21
224 Driving and Operating
check traffic ahead before proceeding. In
addition, three beeps will sound. See“Alert
Type” and“Adaptive Cruise Go Notifier” in
“Collision/Detection Systems” underVehicle
Personalization 0116.
When the vehicle ahead drives away, ACC
resumes automatically if the stop was brief.
If necessary, press RES+ up 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 0212. 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 0115.
{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, indicating ACC 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 on an entrance
or exit ramp. Always be ready to use the
brakes if necessary.
{Warning
On curves, ACC may respond to a vehicle
in another lane, or may not have time to
react to a vehicle in your lane. You could
crash into a vehicle ahead of you, or lose
control of your vehicle. Give extra
attention in curves and be ready to use
the brakes if necessary. Select an
appropriate speed while driving in curves.
ACC may operate differently in a sharp
curve. It may reduce the vehicle speed if the
curve is too sharp.

15481080) - 2022 - CRC - 6/1/21
Driving and Operating 225
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.
When following a vehicle and entering a
curve, ACC may not detect the vehicle ahead
and accelerate to the set speed. When this
happens, the vehicle ahead indicator will not
appear.
ACC may detect a vehicle that is not in your
lane and apply the brakes.ACC may occasionally provide an alert and/
or braking that is considered unnecessary.
It could respond to vehicles in different
lanes or stationary objects when entering or
exiting a curve. This is normal operation.
The vehicle does not need service.
Other Vehicle Lane Changes
ACC will not detect a vehicle ahead until it
is completely in the lane. The brakes may
need to be manually applied.
Objects Not Directly in Front of Your
Vehicle
The detection of objects in front of the
vehicle may not be possible if:
.The vehicle or object ahead is not within
your lane.
.The vehicle ahead is shifted, not centered,
or is shifted to one side of the lane.
Driving in Narrow Lanes
Vehicles in adjacent traffic lanes or roadside
objects may be incorrectly detected when
located along the roadway.
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.

Driving and Operating 231
Park Assist
With RPA, and if equipped with 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) high 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
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. 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 PA 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. Rear Park Assist symbols can be turned on
or off through vehicle personalization. See
“Collision/Detection Systems”
underVehicle
Personalization 0116.
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.
{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 (Continued)

Warning (Continued)
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 switch
Oon the center console 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.
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, touch icons on
screen during the search process or,
if available, change the parking mode in the
infotainment display.
After completely passing a large enough
space, an audible beep occurs.
A red stop symbol and a shift to reverse
message are displayed.
If the vehicle is in R (Reverse), but does not
steer into the expected space, this may be
because the system is maneuvering the
vehicle into a previously detected space. The
APA system does not need service.
APA will instruct the vehicle to stop once a
large enough space is found.
Follow the displayed instructions.
Shift to R (Reverse) to engage automatic
steering. The steering wheel will vibrate
briefly as a reminder to remove hands from
the steering wheel. APA uses idle speed and
braking to park. If idle speed is not
sufficient, gently press the accelerator.
Check surroundings and be prepared to stop
to avoid vehicles, pedestrians, or objects not
detected by the system.
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.

Buick Encore GX Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
15481080) - 2022 - CRC - 6/1/21
Driving and Operating 233
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. See “Collision/
Detection Systems” underVehicle
Personalization 0116.
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.

Buick Encore GX Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
15481080) - 2022 - CRC - 6/1/21
234 Driving and Operating
FCA detects vehicles within a distance of
approximately 60 m (197 ft) and operates at
speeds above 8 km/h (5 mph).
{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
objects. Be ready to take action and
apply the brakes. SeeDefensive Driving
0 191.
FCA can be disabled through vehicle
personalization. See “Collision/Detection
Systems” underVehicle Personalization
0 116.
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.
{Warning
FCA does not provide a warning to help
avoid a crash, unless it detects a vehicle.
FCA may not detect a vehicle ahead if
the FCA sensor is blocked by dirt, snow,
or ice, or if the windshield is damaged.
It may also not detect a vehicle on
winding or hilly roads, or in conditions
that can limit visibility such as fog, rain,
(Continued)
Warning (Continued)
or snow, or if the headlamps or
windshield are not cleaned or in proper
condition. Keep the windshield,
headlamps, and FCA sensors clean and in
good repair.
Collision Alert
If Head-Up Display (HUD) is not equipped,
when your vehicle approaches another
detected vehicle too rapidly, the red FCA
display will flash on the windshield.

Buick Encore GX Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
15481080) - 2022 - CRC - 6/1/21
Driving and Operating 235
If Head-Up Display (HUD) is equipped and
the screen is closed, when your vehicle
approaches another detected vehicle too
rapidly, the HUD with the integrated RLAD
can display red spots reflected in the
windshield.
If Head-Up Display (HUD) is equipped and
the screen is open, when your vehicle
approaches another detected vehicle too
rapidly, the HUD can display indicator on
the screen as the FCA display.
Also, eight rapid high-pitched beeps will
sound from the front. When this Collision
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 Collision Alert occurs.
Tailgating Alert
The vehicle ahead indicator will display
amber when you are following a vehicle
ahead too closely.
Selecting the Alert Timing
The Collision Alert control is on the steering
wheel. Press
[to set the FCA timing to
Far, Medium, or Near. The first button press shows the current setting on the DIC.
Additional button presses will change this
setting. The chosen setting will remain until
it is changed and will affect the timing of
both the Collision Alert and the Tailgating
Alert features. The timing of both alerts will
vary based on vehicle speed. The faster the
vehicle speed, the farther away the alert will
occur. Consider traffic and weather
conditions when selecting the alert timing.
The range of selectable alert timings may
not be appropriate for all drivers and driving
conditions.
If your vehicle is equipped with Adaptive
Cruise Control (ACC), changing the FCA
timing setting automatically changes the
following gap setting (Far, Medium,
or Near).
Following Distance Indicator
The following distance to a moving vehicle
ahead in your path is indicated in following
time in seconds on the Driver Information
Center (DIC). See
Driver Information Center
(DIC) (Base Level) 0107 or
Driver Information Center (DIC) (Uplevel)
0 109. The minimum following time is
0.5 seconds away. If there is no vehicle
detected ahead, or the vehicle ahead is out
of sensor range, dashes will be displayed.
