198 Driving and Operating ABS does not change the time
needed to get a foot on the brake
pedal and does not always
decrease stopping distance. If you
get too close to the vehicle ahead,
there will not be enough time to
apply the brakes if that vehicle
suddenly slows or stops. Always
leave enough room ahead to stop,
even with ABS.
Using ABS Do not pump the brakes. Just hold
the brake pedal down firmly.
Hearing or feeling ABS operate is
normal.
Braking in Emergencies ABS allows steering and braking at
the same time. In many
emergencies, steering can help
even more than braking. Electric Parking Brake
The vehicle has an Electric Parking
Brake (EPB). The EPB can always
be activated, even if the ignition is
off. To prevent draining the battery,
avoid repeated cycles of the EPB
system when the engine is not
running.
The system has a
Y or PARK
Electric Parking Brake light,
and a
8 Service Parking Brake
light. See Electric Parking Brake
Light 0 124 and
Service Electric Parking Brake Light
0 125 . Before leaving the vehicle, check for
the
Y or PARK light to ensure that
the parking brake is applied.
EPB Apply To apply the EPB:
1. Be sure the vehicle is at a
complete stop.
2. Press the EPB switch
momentarily.
The
Y or PARK light will flash and
then stay on once the EPB is fully
applied. If the
Y or PARK light
flashes continuously, then the EPB
is only partially applied or there is a
problem with the EPB. A DIC
message will display. Release the
EPB and try to apply it again. If the
light does not come on, or keeps
flashing, have the vehicle serviced.
Do not drive the vehicle if the
Y or
PARK light is flashing. See your
dealer. See Electric Parking Brake
Light 0 124 .

Buick Enclave Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

Driving and Operating 199If the
8 light is on, press the EPB
switch and hold it. Continue to hold
the switch until the
Y or PARK
light remains on. If the
8 light
remains on, see your dealer.
If the EPB is applied while the
vehicle is moving, the vehicle will
decelerate as long as the switch is
pressed. If the switch is pressed
until the vehicle comes to a stop,
the EPB will remain applied.
The vehicle may automatically apply
the EPB in some situations when
the vehicle is not moving. This is
normal, and is done to periodically
check the correct operation of the
EPB system.
If the EPB fails to apply, block the
rear wheels to prevent vehicle
movement.
EPB Release
To release the EPB:
1. Turn the ignition on or to ACC/
ACCESSORY.
2. Apply and hold the brake
pedal. 3. Press the EPB switch
momentarily.
The EPB is released when the
Yor PARK light is off.
If the
8 light is on, release the EPB
by pressing and holding the EPB
switch. Continue to hold the switch
until the
Y or PARK light is off.
If either light stays on after release
is attempted, see your dealer.
CautionDriving with the parking brake on
can overheat the brake system
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
0 234 .
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.

206 Driving and Operating Erasing Speed Memory
The cruise control set speed is
erased from memory if
5 is pressed
or the ignition is turned off.
Adaptive Cruise Control If equipped with Adaptive Cruise
Control (ACC), it allows for selecting
the cruise control set speed and
following gap. Read this entire
section before using this system.
ACC uses a radar sensor to detect
other vehicles. See Radio
Frequency Statement 0 354 . The
following gap is the following time
(or distance) between your vehicle
and a vehicle detected directly
ahead in your path, moving in the
same direction. If no vehicle is
detected in your path, ACC works
like regular cruise control.
If a vehicle is detected in your path,
ACC can speed up the vehicle or
apply limited, moderate braking to
maintain the selected following gap.
To disengage ACC, apply the brake.
If the Traction Control System (TCS)
or StabiliTrak/Electronic Stability Control (ESC) system activates
while ACC is engaged, ACC may
automatically disengage. See
Traction Control/Electronic Stability
Control 0 200 . When road
conditions allow ACC to be safely
used, ACC can be turned back on.
ACC will not engage if the TCS or
StabiliTrak/ESC electronic stability
control system is disabled.
{ WarningACC has limited braking ability
and may not have time to slow
the vehicle down enough to avoid
a collision with another vehicle
you are following. This can occur
when vehicles suddenly slow or
stop ahead, or enter your lane.
Also see “ Alerting the Driver ” in
this section. Complete attention is
always required while driving and
you should be ready to take
action and apply the brakes. See
Defensive Driving 0 166 .{ WarningACC will not detect or brake for
children, pedestrians, animals,
or other objects.
Do not use ACC when:
.
On winding and hilly roads
or when the sensors are
blocked by snow, ice, or dirt.
The system may not detect
a vehicle ahead. Keep the
entire front of the vehicle
clean.
.
Visibility is low, such as in
fog, rain, or snow
conditions. ACC
performance is limited under
these conditions.
.
On slippery roads where
fast changes in tire traction
can cause excessive
wheel slip.

13527524) - 2020 - CRC - 4/10/19
212 Driving and Operating two minutes or if the driver door is
opened and the driver seat belt is
unbuckled, ACC automatically
applies the Electric Parking Brake
(EPB) and the vehicle will shift to
P (Park) to hold the vehicle. The
EPB status light will turn on. See
Electric Parking Brake 0 198 . To
resume ACC and 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, the ACC indicator
turns blue on the instrument cluster.
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
{ WarningOn 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
