196 Driving and Operating
Manual Mode Electronic Range Select (ERS)
CautionDriving with the engine at a high
rpm without upshifting while using
Manual Mode, could damage the
vehicle. Always upshift when
necessary while using
Manual Mode.
Electronic Range Select (ERS),
or Manual Mode, allows for the
selection of the range of gear positions. Use this mode when
driving downhill or towing a trailer to
limit the top gear and vehicle speed.
The shift position indicator within the
Driver Information Center (DIC) will
display a number next to the L
indicating the highest available gear.
To enter Electronic Range Select or
Manual Mode:
1. With the vehicle in D (Drive),
pull back on the shift lever to
activate L (Low). The L in the
shift pattern will illuminate in
red, and the D will switch to
white.
2. Tap the left steering wheel
control to reduce the highest
gear available, or the right
control to increase the highest
gear available.
3. To exit, pull back on the shift
lever a second time. The D in
the shift pattern will illuminate
in red, and the L will switch to
white.
When shifting to L (Low), the
transmission will shift to a preset
lower gear range. For this preset range, the highest gear available
will be displayed next to the L in the
DIC. All gears below that number
are available to use. For example,
when 4 (Fourth) is shown next to
the L, 1 (First) through 4 (Fourth)
gears are shifted automatically. To
shift to 5 (Fifth) gear, tap the right
steering wheel control or shift into D
(Drive).
L (Low) will prevent shifting to a
lower gear range if the engine
speed is too high. If the vehicle
speed is not reduced within the time
allowed, the lower gear range shift
will not be completed. Slow the
vehicle, then tap the left steering
wheel control to the desired lower
gear range.
Cruise control can be used while
in ERS.
Tow/Haul Mode This feature can assist when towing
or hauling a heavy load. To activate

and cause premature wear or
damage to brake system parts.
Make sure that the parking brake
is fully released and the brake
warning light is off before driving.
Automatic EPB Release
The EPB will automatically release if
the vehicle is running, placed into
gear, and an attempt is made to drive away. Avoid rapid acceleration
when the EPB is applied, to
preserve parking brake lining life.
If parking on a hill, or if the vehicle
is pulling a trailer, see Driving
Characteristics and Towing Tips

Brake Assist Brake Assist detects rapid brake
pedal applications due to
emergency braking situations and
provides additional braking to
activate the Antilock Brake System
(ABS) if the brake pedal is not
pushed hard enough to activate
ABS normally. Minor noise, brake
pedal pulsation, and/or pedal
movement during this time may
occur. Continue to apply the brake
pedal as the driving situation
dictates. Brake Assist disengages
when the brake pedal is released.

Tips 0 234 . Tow/Haul Mode is
available on vehicles with the Trailer
Towing Package. Cruise Control With cruise control the vehicle can
maintain a speed of about 40 km/h
(25 mph) or more without keeping
your foot on the accelerator. Cruise
control does not work at speeds
below 40 km/h (25 mph).
{ WarningCruise control can be dangerous
where you cannot drive safely at
a steady speed. Do not use
cruise control on winding roads or
in heavy traffic.
Cruise control can be dangerous
on slippery roads. On such roads,
fast changes in tire traction can
cause excessive wheel slip, and
you could lose control. Do not use
cruise control on slippery roads.

Driving and Operating 213Warning (Continued)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.
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, signs, guardrails, and other
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.
Do Not Use ACC on Hills and
When Towing a Trailer

214 Driving and Operating 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. The
driver will often need to take over
acceleration and braking on steep
hills, especially when towing a
trailer. If the brakes are applied, the
ACC disengages.
Disengaging ACC
There are three ways to
disengage ACC:

or if the ignition is turned off. Cleaning the Sensing System
The radar sensor on the front of the
vehicle can become blocked by
snow, ice, dirt, or mud. This area
needs 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 ” previously
in this section. Always consider
driving conditions before using
either cruise control system.
For cleaning instructions, see
“ Washing the Vehicle ” under
Exterior Care 0 317 .
System operation may also be
limited under snow, heavy rain,
or road spray conditions. 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.
{ WarningDo 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

220 Driving and Operating
{ WarningThe Park Assist system does not
detect children, pedestrians,
bicyclists, animals, or objects
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 backing.
The instrument cluster may have a
Park Assist display with bars that
show “ distance to object ” and object
location information for RPA. 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, five
beeps will sound from the rear,
or both sides of the Safety Alert
Seat will pulse five times.
Rear Cross Traffic Alert (RCTA)
If equipped, RCTA shows 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, 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 To turn RPA on or off, press
X on
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.
RCTA and Rear Park Assist
symbols can be turned on or off
through vehicle personalization. See
“ Collision/Detection Systems ” under
Vehicle Personalization 0 137 .
Turn off RPA when towing a trailer.

224 Driving and Operating Warning (Continued)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 Parking
Brake (EPB) to hold the vehicle at a
stop. Release the EPB or firmly
press the accelerator pedal.
{ 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. 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.
{ WarningIBA 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. See
“ Collision/Detection Systems ” under
Vehicle Personalization 0 137 .{ WarningUsing 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

Buick Enclave Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
13527524) - 2020 - CRC - 4/10/19
226 Driving and Operating When the vehicle approaches a
pedestrian ahead too rapidly, the
red FPB alert display will flash on
the windshield. Eight rapid
high-pitched beeps will sound from
the front, or both sides of the Safety
Alert Seat will pulse five times.
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.
{ WarningFPB 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. See
“ Front Pedestrian Detection ” in
“ Collision/Detection Systems ” under
Vehicle Personalization 0 137 .
{ WarningUsing 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.

228 Driving and Operating
Left Outside
Mirror Display Right Outside
Mirror Display
When the vehicle is started, both
outside mirror LCA displays will
briefly come on to indicate the
system is operating. When the
vehicle is in a forward gear, the left
or right outside mirror display will
light up if a moving vehicle is
detected in the next lane over in that
blind zone or rapidly approaching
that zone. If the turn signal is
activated in the same direction as a
detected vehicle, this display will
flash as an extra warning not to
change lanes.
LCA can be disabled. When you
disable LCA, Side Blind Zone Alert
is also disabled. See “ Collision/
Detection Systems ” under Vehicle
Personalization 0 137 . If LCA is
disabled by the driver, the LCA
mirror displays will not light up. When the System Does Not
Seem to Work Properly The LCA system requires some
driving for the system to calibrate to
maximum performance. This
calibration may occur more quickly if
the vehicle is driving on a straight
highway road with traffic and
roadside objects (e.g., guardrails,
barriers).
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" under Exterior Care 0 317 .
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.
