Driving and Operating 197Approaching and Following a
Vehicle
The vehicle ahead indicator is in the
instrument cluster and HUD,
if equipped.
The vehicle ahead indicator 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 the vehicle in front at the
selected follow gap. The vehicle
speed increases or decreases to
follow the vehicle in front of you, but
will not exceed the 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.
Stationary or Very Slow-Moving
Objects
{ WarningACC 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. ACC Automatically Disengages
ACC may automatically disengage
and the driver will need to manually
apply the brakes to slow the
vehicle if:
.
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 a
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.
A message will appear on the DIC
indicating that ACC is disengaging.
The ACC active indicator will turn
white when ACC is no longer active.
Notification to Resume ACC
ACC will maintain a follow gap
behind a detected vehicle and slow
your vehicle to a stop behind that
vehicle.

13555857) - 2020 - CRC - 2/25/19
198 Driving and Operating If the stopped vehicle ahead has
driven away and ACC has not
resumed, the vehicle ahead
indicator will flash as a reminder to
check traffic before proceeding. In
addition, three beeps will sound.
See “ Adaptive Cruise Go Notifier ” in
“ Collision/Detection Systems ” under
Vehicle Personalization 0 133 .
When the vehicle ahead drives
away, press RES+ 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 0 186 . To release the
EPB, press the accelerator pedal.
A DIC warning message may
display indicating to shift to P (Park)
before exiting the vehicle. { WarningIf 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.
{ WarningLeaving 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, automatic braking will
not occur. The ACC indicator will turn blue on the instrument cluster
and HUD, if equipped. ACC will
resume operation when the
accelerator pedal is not being
pressed.
{ WarningThe 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

204 Driving and Operating
{ WarningThe 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.
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 1.8 m (6 ft) behind 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.
{ WarningThe 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 RPA, and on
some vehicles, FPA. 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, or both sides of the
Safety Alert Seat will pulse two
times. 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

Driving and Operating 205location, or both sides of the Safety
Alert Seat will pulse five times.
Beeps for FPA are higher pitched
than for RPA.
Rear Cross Traffic Alert (RCTA)
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,
or three Safety Alert Seat pulses
occur on the left or right side,
depending on the direction of the
detected vehicle.
Turning the Features On or Off
Press
X on the center stack to
turn on or off the Front and Rear
Park Assist and the Rear Cross
Traffic Alert (RCTA). The indicator
light in the button comes on when the features are on and turns off

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,
and control the brakes and
accelerator. A display and audible
beeps help to guide parking
maneuvers. { WarningAPA does not apply the brakes.
APA may not detect objects in the
parking space, objects that are
soft or narrow, objects high off the
ground such as flatbed trucks,
or objects below ground level
such as large potholes. 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
O on 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.

13555857) - 2020 - CRC - 2/25/19
206 Driving and Operating 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.
If the vehicle is equipped with
perpendicular parking mode, press
and hold

process to switch the APA parking
mode between perpendicular and
parallel parking.
APA searches for parking spaces to
the right of the vehicle. To search for
a parking space to the left, turn on
the left turn signal. APA will instruct the vehicle to stop
once a large enough space is found.
Follow the displayed instructions.
When instructed to drive in reverse,
shift to R (Reverse) to engage
automatic steering. The steering
wheel will briefly vibrate as a
reminder to remove hands from the
steering wheel. Check surroundings
and continue braking or accelerating
as needed, and be prepared to stop
to avoid vehicles, pedestrians,
or objects.
If the vehicle exceeds 10 km/h
(6 mph), APA is automatically
disengaged and automatic steering
will turn off. 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. Upon successful
completion of a maneuver, APA will
beep and display a PARKING
COMPLETE message. 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.
.
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.
To cancel APA, press
O again.
When the System Does Not Seem
to Work Properly

Driving and Operating 207
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), and/or Automatic Emergency
Braking (AEB) 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 40 km/h (25 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 0 192 .
{ WarningFCA 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 0 163 .
FCA can be disabled with either the
FCA steering wheel control or,
if equipped, through vehicle personalization. See “ Collision/
Detection Systems ” under Vehicle
Personalization 0 133 .
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.

Buick Envision Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
13555857) - 2020 - CRC - 2/25/19
208 Driving and Operating
{ WarningFCA 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,
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. Cruise control may be
disengaged when the Collision Alert
occurs. Tailgating Alert
The vehicle ahead indicator will
display amber when you are
following a detected vehicle ahead
much too closely.
Selecting the Alert Timing The Collision Alert control is on the
steering wheel. Press
3 or
[ 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 Driver
Information Center (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.
