98 Lighting
This indicator light turns on in the
instrument cluster when the high-beam
headlamps are on.
Flash-to-Pass
To flash the high beams, pull the turn signal
lever all the way toward you. Then
release it.
Daytime Running Lamps (DRL)
Daytime Running Lamps can make it easier
for others to see the front of your vehicle
during the day. Fully functional DRL are
required on all vehicles first sold in Canada.
A light sensor on top of the instrument
panel makes the DRL work, so be sure it is
not covered.The DRL system makes the low-beam
headlamps come on at a reduced brightness
when the following conditions are met:
.The ignition is on.
.The exterior lamp control is in AUTO.
.The engine is running.
When the DRL are on, the taillamps,
sidemarker, instrument panel, and other
lamps will not be on.
The headlamps automatically change from
DRL to the regular headlamps depending on
the darkness of the surroundings. The other
lamps that come on with the headlamps will
also come on.
When it is bright enough outside, the
headlamps go off and the DRL come on.
The DRL turn off when the headlamps are
turned to
Oor the ignition is off. For
vehicles first sold in Canada, this control
only works when the vehicle is parked.
Automatic Headlamp System
When it is dark enough outside and the
exterior lamp control is in the automatic
position, the headlamps come on
automatically. See Exterior Lamp Controls
0 97.
The vehicle has a light sensor on top of the
instrument panel. Make sure it is not
covered, or the headlamps will be on when
they are not needed.
The system may also turn on the headlamps
when driving through a parking garage or
tunnel.

Rear Cross Traffic Alert (RCTA)
On vehicles with the RCTA, a warning
triangle with a left or right pointing arrow
may appear on the infotainment display to
warn of traffic coming from the left or the
right. Three beeps will sound from the
speaker on that side. This system detects
objects coming from up to 20 m (65 ft) from
the left or right side behind the vehicle. The
RCTA system will not work properly if ice,
snow, mud, or anything else builds up on
the rear bumper sensors.
Park Assist
If equipped, the Front and Rear Park Assist
(FRPA) system assists you with parking and
avoiding objects. FRPA operates at speeds
less than 8 km/h (5 mph). The sensors on
the front and rear bumper detect objects up
to 1.2 m (4 ft) in front of the vehicle, 2.5 m
(8 ft) behind the vehicle, and at least 25 cm
(10 in) off the ground and below liftgate
level. This detection distance may be less
during warmer or humid weather.
{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.
How the System Works
When the vehicle is shifted into R (Reverse)
the front and rear sensors are automatically
turned on. After the vehicle is shifted out of
R (Reverse), the rear sensors are turned off
and the front sensors stay on until the
vehicle is above a speed of 8 km/h (5 mph).
For the front Park Assist system to be active
again without shifting into R (Reverse),
X
must be pressed. See“Turning the System
On and Off” later in this section.
When the vehicle is in N (Neutral), the
system may be active. If the vehicle is in a
car wash, the sensors may detect objects in the car wash. See
“Turning the System On
and Off” later in this section to turn the
system off.
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.
Objects Detected by Both the Front and Rear
Sensors
In general, if objects are detected at the
same time near both the front and rear
bumpers while backing up, the beeps only
sound to indicate that objects are close to
the rear bumper.
However, if an object comes within 0.3 m
(1 ft) of the front bumper while the vehicle
is backing up and at the same time there is
another object further than 0.3 m (1 ft) from
the rear bumper, then higher-pitched beeps
only sound to indicate the front object.
Turning the System On and Off
The FRPA system can be turned on and off
by pressing
Xon the center stack.

192 Driving and Operating
The indicator light in the button comes on
when the system is turned on.
When the system is off, the indicator light
in the button is off or PARK ASSIST OFF
briefly displays on the Driver Information
Center (DIC).
FRPA defaults to the on setting each time
the vehicle is started.
When the System Does Not Seem to
Work Properly
If the FRPA system does not activate due to
a temporary condition, a message may
display on the DIC. This can occur under the
following conditions:
.The driver has disabled the system.
.The sensors are not clean. Keep the
vehicle's bumpers free of mud, dirt, snow,
ice, and slush. For cleaning instructions,
seeExterior Care 0258.
.The Park Assist sensors are 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.
.An object was hanging out of the liftgate
during the last drive cycle. Once the
object is removed, FRPA will return to
normal operation.
.An object or cover is attached to the front
of the vehicle.
.The bumper is damaged. Take the vehicle
to your dealer to repair the system.
.Other conditions, such as vibrations from
a jackhammer or the compression of air
brakes on a very large truck, are affecting
system performance.
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 detects vehicles within a distance of
approximately 60 m (197 ft) and operates at
speeds above 40 km/h (25 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. See Defensive Driving
0 165.
FCA can be disabled with either the FCA
steering wheel control or, if equipped,
through vehicle personalization. See
“Collision/Detection Systems” underVehicle
Personalization (8 Inch Screen) 089 or
Vehicle Personalization (7 Inch Screen) 094.

Driving and Operating 193
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
When your vehicle approaches another
detected vehicle too rapidly, the FCA display
will flash on the windshield. 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.
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. The timing of
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.

194 Driving and Operating
Unnecessary Alerts
FCA may provide unnecessary alerts to
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.
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. The SBZA warning display will light
up in the corresponding outside side mirror
and will flash if the turn signal is on.
{Warning
SBZA does not alert the driver to vehicles
rapidly approaching outside of the side
blind zones, pedestrians, bicyclists,
or animals. It may not provide alerts
when changing lanes under all driving
conditions. Failure to use proper care
when changing lanes may result in injury,
death, or vehicle damage. Before making
a lane change, always check mirrors,
glance over your shoulder, and use the
turn signals.
SBZA Detection Zones
The SBZA sensor covers a zone of
approximately one lane over from both
sides of the vehicle, or 3.5 m (11 ft). The
height of the zone is approximately between
0.5 m (1.5 ft) and 2 m (6 ft) off the ground.
This zone starts at approximately the middle
of the vehicle and goes back 5 m (16 ft).
How the System Works
The SBZA symbol lights up in the side
mirrors when the system detects a moving
vehicle in the next lane over that is in the
side blind zone. This indicates it may be
unsafe to change lanes. Before making a
lane change, check the SBZA display, check
mirrors, glance over your shoulder, and use
the turn signals.
Left Side Mirror DisplayRight Side Mirror Display
When the vehicle is started, both outside
mirror SBZA displays will briefly come on to
indicate the system is operating. When the
vehicle is in a forward gear, the left- or

Buick Encore Owner Manual (GMNA-Localizing-U.S./Canada-14607636) -
2021 - CRC - 8/18/20
Driving and Operating 195
right-side mirror display will light up if a
moving vehicle is detected in that blind
zone. If the turn signal is activated in the
same direction of a detected vehicle, this
display will flash as an extra warning not to
change lanes.
SBZA can be disabled through vehicle
personalization. See“Collision/Detection
Systems” underVehicle Personalization (8
Inch Screen) 089 or
Vehicle Personalization (7 Inch Screen) 094.
If SBZA is disabled by the driver, the SBZA
mirror displays will not light up.
When the System Does Not Seem to
Work Properly
SBZA displays may not come on when
passing a vehicle quickly or for a stopped
vehicle. SBZA may alert to objects attached
to the vehicle, such as a bicycle, or object
extending out to either side of the vehicle.
This is normal system operation; the vehicle
does not need service.
SBZA may not always alert the driver to
vehicles in the side blind zone, especially in
wet conditions. 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.
SBZA may not operate when the SBZA
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" under
Exterior Care0258. 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 SBZA displays do not light up when
vehicles are in the blind zone and the
system is clean, the system may need
service. Take the vehicle to your dealer.
When SBZA is disabled for any reason other
than the driver turning it off, the Side Blind
Zone Alert On option will not be available
on the personalization menu.
Radio Frequency Information
See Radio Frequency Statement 0290.
Lane Departure Warning (LDW)
If equipped, LDW may help avoid crashes
due to unintentional lane departures. LDW
uses a camera sensor to detect the lane markings at speeds of 56 km/h (35 mph) or
greater. It may provide an alert if the
vehicle is crossing a lane without using a
turn signal in that direction. LDW light will
not alert if the turn signal is active in the
direction of lane departure, or if LDW
detects that you are accelerating, braking or
actively steering.
{Warning
The LDW system does not steer the
vehicle. The LDW system may not:
.Provide enough time to avoid a 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.
If LDW only detects lane markings on one
side of the road, it will only warn you
when departing the lane on the side
where it has detected a lane marking.
Always keep your attention on the road (Continued)

196 Driving and Operating
Warning (Continued)
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 LDW in bad weather conditions.
How the System Works
LDW utilizes camera sensor installed on the
windshield ahead of the rearview mirror to
detect lane markings.
To turn LDW on and off, press
@on the
center stack. The control indicator will light
when LDW is on.
When LDW is on,
@is green if LDW is
available to warn of a lane departure. If the
vehicle crosses a detected lane marking
without using the turn signal in that
direction,
@changes to amber and flashes.
Additionally, there will be three beeps on
the right or left, depending on the lane
departure direction. LDW will not alert if the
turn signal is active in the direction of lane
departure, or if LDW detects that you are
accelerating, braking or actively steering.
