200 Driving and Operating
Hill Start Assist (HSA)
{ WarningDo not rely on the HSA feature.
HSA does not replace the need to
pay attention and drive safely.
You may not hear or feel alerts or
warnings provided by this system.
Failure to use proper care when
driving may result in injury, death,
or vehicle damage. See
Defensive Driving 0 166 . When the vehicle is stopped on a
grade, Hill Start Assist (HSA)
prevents the vehicle from rolling in
an unintended direction during the
transition from brake pedal release
to accelerator pedal apply. The
brakes release when the accelerator
pedal is applied. If the accelerator
pedal is not applied within a few
minutes, the Electric Parking Brake
will apply. The brakes may also
release under other conditions. Do
not rely on HSA to hold the vehicle.
HSA is available when the vehicle is
facing uphill in a forward gear,
or when facing downhill in
R (Reverse). The vehicle must
come to a complete stop on a grade
for HSA to activate. Ride Control Systems Traction Control/
Electronic Stability
Control System Operation The vehicle has a Traction Control
System (TCS) and StabiliTrak/
Electronic Stability Control (ESC),
an electronic stability control
system. These systems help limit
wheel slip and assist the driver in
maintaining control, especially on
slippery road conditions.
TCS activates if it senses that any
of the drive wheels are spinning or
beginning to lose traction. When this
happens, TCS applies the brakes to
the spinning wheels and reduces
engine power to limit wheel spin.
StabiliTrak/ESC activates when the
vehicle senses a difference between
the intended path and the direction
the vehicle is actually traveling.
StabiliTrak/ESC selectively applies
braking pressure to any one of the

Buick Enclave Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
13527524) - 2020 - CRC - 4/10/19
Driving and Operating 201vehicle wheel brakes to assist the
driver in keeping the vehicle on the
intended path.
If cruise control is being used and
TCS or StabiliTrak/ESC begins to
limit wheel spin, cruise control will
disengage. Cruise control may be
turned back on when road
conditions allow. TCS and
StabiliTrak/ESC will automatically
turn on when cruise control is set.
Both systems come on
automatically when the vehicle is
started and begins to move. The
systems may be heard or felt while
they are operating or while
performing diagnostic checks. This
is normal and does not mean there
is a problem with the vehicle.
It is recommended to leave both
systems on for normal driving
conditions, but it may be necessary
to turn TCS off if the vehicle gets
stuck in sand, mud, ice, or snow.
See If the Vehicle Is Stuck 0 176
and “ Turning the Systems Off and
On ” later in this section. The indicator light for both systems
is in the instrument cluster. This
light will:
.
Flash when TCS is limiting
wheel spin.
.
Flash when StabiliTrak/ESC is
activated.
.
Turn on and stay on when either
system is not working.
If either system fails to turn on or to
activate, a message displays in the
Driver Information Center (DIC), and
d comes on and stays on to
indicate that the system is inactive
and is not assisting the driver in
maintaining control. The vehicle is
safe to drive, but driving should be
adjusted accordingly.
If
d comes on and stays on:
1. Stop the vehicle. 2. Turn the engine off and wait
15 seconds.
3. Start the engine.
4. Drive the vehicle.
If
d comes on and stays on, see
your dealer.

Driver Mode Control Driver Mode Control attempts to add
a sportier feel, provide a more
comfortable ride, or assist in
different weather conditions or
terrain. This system simultaneously
changes the software calibration of
various sub-systems. Depending on
the option package, available
features, and mode selected, the
suspension, steering, and
powertrain will change calibrations
to achieve the desired mode
characteristics. If equipped, the vehicle may have
the following modes: All-Wheel
Drive (AWD), Tour, Sport, and/or
Tow/Haul. When not in AWD, the
vehicle is in Front-Wheel Drive
(FWD) which will provide better fuel
economy. All drive modes may
display indicator or mode on
message in the Driver Information
Center (DIC) except FWD.
AWD Mode
AWD Mode is intended for
conditions which demand more
traction. In AWD Mode, the AWD
system delivers power to all four
wheels and the system adjusts as

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

Mode, the steering and suspension
will change to provide more precise
control and better cornering
performance. Sport Mode is only
available on vehicles equipped with
Real Time Damping. Sport Mode
also changes the StabiliTrak and
AWD settings to allow more
wheel slip.
Tow/Haul Mode If equipped, Tow/Haul Mode can
assist when towing or hauling a
heavy load. It changes transmission
shift patterns, and increases trailer
sway control assistance. See
Driving Characteristics and Towing
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.

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.
