regular cruise control is activated, a green
Jindicator will be lit on the instrument
cluster; the following gap will not display.
When the vehicle is turned on, the cruise
control mode will be set to the last mode
used before the vehicle was turned off.
{Warning
Always check the cruise control indicator
on the instrument cluster to determine
which mode cruise control is in before
using the feature. If ACC is not active, the
vehicle will not automatically brake for
other vehicles, which could cause a crash
if the brakes are not applied manually.
You and others could be seriously injured
or killed.
Setting Adaptive Cruise Control
If
Jis on when not in use, it could get
pressed and go into ACC when not desired.
Keep the cruise control off when cruise is
not being used.
Select the set speed desired for ACC. This is
the vehicle speed when no vehicle is
detected in its path. While the vehicle is moving, ACC will not set
at a speed less than 5 km/h (3 mph),
although it can be resumed. The minimum
allowable set speed is 25 km/h (15 mph).
To set ACC:
1. Press
J.
2. Get up to the desired speed.
3. Press and release SET– .
4. Remove your foot from the accelerator pedal.
After ACC is set, it may immediately apply
the brakes if a vehicle ahead is detected
closer than the selected following gap.
ACC can also be set while the vehicle is
stopped if ACC is on and the brake pedal is
applied.
The ACC indicator displays in the instrument
cluster and Head-Up Display (HUD),
if equipped. When ACC is turned on, the
indicator will be lit white. When ACC is
active, the indicator will turn green. Be mindful of speed limits, surrounding
traffic speeds, and weather conditions when
selecting the set speed.
Resuming a Set Speed
If the ACC is set at a desired speed and then
the brakes are applied, ACC is disengaged
without erasing the set speed from memory.

A DIC warning message may display
indicating to shift to P (Park) before exiting
the vehicle.
{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 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.
If equipped, the curve speed control
indicator
bmay illuminate green when
ACC is actively controlling the vehicle speed
and detects a sharp curve on the road
ahead.
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.

Weather Conditions Affecting ACC
System operation may be limited under
snow, heavy rain, or road spray conditions.
Accessory Installations and Vehicle
Modifications
Do not install or place any object around
the front camera windshield area that would
obstruct the front camera view.
Do not install objects on top of the vehicle
that overhang and obstruct the front
camera, such as a canoe, kayak, or other
items that can be transported on a roof rack
system. SeeRoof Rack System 080.
Do not modify the hood, headlamps, or fog
lamps, as this may limit the camera’s ability
to detect an object.
Cleaning the Sensing System
The camera sensor on the windshield ahead
of the rearview mirror and the radar sensors
on the front of the vehicle can become
blocked by snow, ice, dirt, mud, or debis.
These areas need to be cleaned for ACC to
operate properly. If ACC will not operate, regular cruise control
may be available. See
“Switching Between
ACC and Regular Cruise Control” in this
section. Always consider driving conditions
before using either cruise control system.
For cleaning instructions, see “Washing the
Vehicle” underExterior Care 0311.
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 0190.

limited and objects that are close to either
corner of the bumper or under the bumper
do not display.
A warning triangle may appear on the
infotainment display to show that Rear Park
Assist (RPA) or Rear Cross Traffic Alert (RCTA)
has detected an object. This triangle changes
from amber to red and increases in size the
closer the object.
{Warning
The camera(s) do not display children,
pedestrians, bicyclists, crossing traffic,
animals, or any other object outside of
the cameras’
field of view, below the
bumper, or under the vehicle. Shown
distances may be different from actual
distances. Do not drive or park the
vehicle using only these camera(s).
Always check behind and around the
vehicle before driving. Failure to use
proper care may result in injury, death,
or vehicle damage.
Surround Vision System
If equipped, Surround Vision shows an
image of the area surrounding the vehicle,
along with the front or rear camera views
on the infotainment display. The front
camera is in the grille or near the front
emblem, the side cameras are on the
bottom of the outside mirrors, and the rear
camera is above the license plate.
The Surround Vision system can be accessed
by selecting CAMERA in the infotainment
display or when the vehicle is shifted into
R (Reverse). To return to the previous screen
sooner, when not in R (Reverse) press Home
or Back on the infotainment system, shift
into P (Park), or reach a vehicle speed of
approximately 12 km/h (8 mph) while in
D (Drive).
{Warning
The Surround Vision cameras have blind
spots and will not display all objects near
the corners of the vehicle. Folding outside
mirrors that are out of position may not
display surround view correctly. Always
check around the vehicle when parking or
backing.

Down can be enabled or disabled by
touching the Top Down View button
multiple times.
Park Assist
The vehicle may be equipped with Rear Park
Assist (RPA) or Front and Rear Park Assist
(FRPA). Under certain conditions, the Park
Assist system can assist the driver during
backing and parking maneuvers when the
vehicle is driven at no more than 9 km/h
(6 mph). An illuminated indicator in the Park
Assist button indicates the system is ready.
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
1.8 m (6 ft) behind and 1.3 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 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. Vehicles equipped with RPA will show the amphitheater at the rear of
the vehicle, and if equipped, FRPA will show
the amphitheater at the front and rear.
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 and Off
The
Xbutton is used to turn on or off
the Park Assist, which also turns on or off
the Backing Warning and Reverse Automatic
Braking (RAB) at the same time. When the

Buick Envision Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
15218978) - 2022 - CRC - 5/12/21
232 Driving and Operating
system is turned off, a system off message
is shown on the display. This message
disappears after a short period of time.
If the vehicle has a trailer hitch attached,
select ON - ATTACHED using the
infotainment system menus to allow Park
Assist to function properly. Park Assist is
able to compensate for a trailer hitch up to
0.3 m (1 ft) in length and width. Park Assist
may not function properly with larger trailer
hitches and provide inaccurate information
of objects in the rear.
Turn off Park Assist when towing a trailer to
prevent unwanted beeps and when a bike
rack is attached to ensure proper operation.
The Park Assist System can also be turned
on or off using the infotainment system.
SeeVehicle Personalization 0110.
When the System Does Not Seem to Work
Properly
If a service message displays, check the
following conditions:
.The sensors may not be clean. Keep the
vehicle's front and rear bumpers free of
mud, dirt, snow, ice, and slush. For
cleaning instructions, see Exterior Care
0 311.
.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)
Enhanced Automatic Parking Assist (APA)
If equipped, under certain conditions
Enhanced Automatic Parking Assist (APA) 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. The vehicle will automatically
maneuver into a detected spot moving at or
near idle speed. It does this by
automatically steering, braking, accelerating,
and gear shifting. The driver must always be
prepared to apply braking if necessary. A
display and beeps help to guide the parking
maneuvers.
{Warning
APA may not always detect objects in the
parking space, objects that are not rigid
(e.g. shrubs and chain-link fences), objects
below the bumper, objects high off the
ground (e.g. flatbed trucks), hanging
objects, objects below ground level such
(e.g. large potholes), or moving objects
(e.g. pedestrians, cyclists, vehicles).
Always verify that the parking space is
appropriate for parking a vehicle. APA (Continued)

Reverse Automatic Braking (RAB)
Backing Warning and Reverse Automatic
Braking (RAB)
Vehicles with Adaptive Cruise Control (ACC)
have the Backing Warning System and
Reverse Automatic Braking (RAB) system.
When in R (Reverse), Backing Warning alerts
of rear objects at vehicle speeds greater
than 8 km/h (5 mph), and RAB may
automatically brake hard at speeds between
1–32 km/h (0.5–20 mph).
The Backing Warning System will beep once
from the rear when an object is first
detected, or pulse twice on both sides of the
Safety Alert Seat. When the system detects
a potential crash, beeps will be heard from
the rear, or five pulses will be felt on both
sides of the Safety Alert Seat. There may
also be a brief, sharp application of the
brakes.
{Warning
The Backing Warning System only
operates at speeds greater than 8 km/h
(5 mph). It does not detect children,
pedestrians, bicyclists, animals, or objects(Continued)
Warning (Continued)
below the bumper or that are too close
or too far from the vehicle. In some
situations, such as at higher backing
speeds, there may not be enough time
for the short, sharp application of the
vehicle brake 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 (Continued)
Warning (Continued)
vehicle. It may not brake or stop in time
to avoid a crash. It will not brake for
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 system. Before releasing (Continued)

pulses occur on the left or right side,
depending on the direction of the detected
vehicle.
Driving With a Trailer
Use caution while backing up when towing
a trailer. The RCTA feature is automatically
disabled when a trailer is attached to the
vehicle.
Turning the Features On or Off
RCTA can be turned on or off using the
infotainment system. See“Collision/
Detection Systems” underVehicle
Personalization 0110.
Assistance Systems for Driving
If equipped, when driving the vehicle in a
forward gear, Forward Collision Alert (FCA),
Lane Keep Assist (LKA), 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 or pulses the driver seat. FCA
also lights an amber visual alert if following
another vehicle much too closely.
FCA detects vehicles within a distance of
approximately 60 m (197 ft) and operates at
speeds above 8 km/h (5 mph). If the vehicle
has Adaptive Cruise Control (ACC), it can
detect vehicles to distances of approximately
110 m (360 ft) and operates at all speeds.
See
Adaptive Cruise Control (Advanced)
0 219.
{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. See Defensive Driving
0 190. FCA can be disabled. See
“Collision/Detection
Systems” underVehicle Personalization
0 110.
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.

238 Driving and Operating
Warning (Continued)
It may also not detect a vehicle on
winding or hilly roads, or in conditions
that can limit visibility such as fog, rain,
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
With Head-Up Display
Without Head-Up Display When your vehicle approaches another
detected vehicle too rapidly, the red FCA
display will flash on the windshield. Also,
eight rapid high-pitched beeps will sound
from the front, or both sides of the Safety
Alert Seat will pulse five times. 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.
Tailgating Alert
The vehicle ahead indicator will display
amber when you are following a vehicle
ahead much 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, or on some vehicles,
Off. 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.

Buick Envision Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
15218978) - 2022 - CRC - 5/12/21
Driving and Operating 239
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). SeeDriver Information Center
(DIC) 0104. The minimum following time is
0.5 seconds away.
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 front-end crashes. AEB
also includes Intelligent Brake Assist (IBA).
When the system detects a vehicle in the
path ahead that is traveling in the same
direction, it can provide a boost to braking,
or automatically brake the vehicle, to avoid
a crash. This can help avoid or lessen the
severity of crashes when driving in a
forward gear. Depending on the situation,
the vehicle may automatically 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 0237.
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.
.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 engage the Electric
