Daytime Running
Lamps (DRL) DRL 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.
The dedicated DRL will come on
when all of the following conditions
are met:
.
The ignition is on.
.
The exterior lamp control is
in AUTO.
.
The light sensor determines it is
daytime.
.
The parking brake is released or
the vehicle is not in P (Park).
The taillamps, instrument panel
lights, and other lamps will not
be on.
The DRL turn off when the
headlamps are turned to
O or the
ignition is off. For vehicles sold in
Canada, this control only works
when the vehicle is parked. Automatic Headlamp
System When the exterior lamp control is
set to AUTO and it is dark enough
outside, the headlamps come on
automatically.
There is a light sensor on top of the
instrument panel. Do not cover the
sensor; otherwise the headlamps
will come on when they are not
needed.
The system may also turn on the
headlamps when driving through a
parking garage or tunnel. If the vehicle is started in a dark
garage, the automatic headlamp
system comes on immediately. If it
is light outside when the vehicle
leaves the garage, there is a slight
delay before the automatic
headlamp system changes to the
Daytime Running Lamps (DRL).
During that delay, the instrument
cluster may not be as bright as
usual. Make sure the instrument
panel brightness control is in the full
bright position. See Instrument
Panel Illumination Control 0 151 .
When it is bright enough outside,
the headlamps will turn off or may
change to DRL.
The automatic headlamp system
turns off when the exterior lamp
control is turned to
O or the ignition
is off.
Lights On with Wipers
If the windshield wipers are
activated in daylight with the engine
on, and the exterior lamp control is
in AUTO, the headlamps, parking
lamps, and other exterior lamps
come on. The transition time for the

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

flashers off. Turn and Lane-Change
Signals
Move the lever all the way up or
down to signal a turn.
An arrow on the instrument cluster
will flash in the direction of the turn
or lane change. Raise or lower the lever until the
arrow starts to flash to signal a lane
change. Hold it there until the lane
change is complete. If the lever is
moved momentarily to the lane
change position, the arrow will flash
three times. It will flash six times if
Tow/Haul Mode is active.
The lever returns to its starting
position when it is released.
If after signaling a turn or lane
change, the arrow flashes rapidly or
does not come on, a signal bulb
may be burned out.
Have any burned out bulbs
replaced. If a bulb is not burned out,
check the fuse. See Instrument
Panel Fuse Block 0 277 .

Exit Lighting Some exterior lamps and interior
lights come on at night, or in areas
with limited lighting, when the driver
door is opened after the ignition is
turned off. The dome lamp comes
on after the ignition is turned off.
The exterior lamps and dome lamp
remain on for a set amount of time,
then automatically turn off.
The exterior lamps turn off
immediately by turning the exterior
lamp control off.
This feature can be changed. See
Vehicle Personalization 0 137 .
Battery Load
Management The vehicle has Electric Power
Management (EPM) that estimates
the battery's temperature and state
of charge. It then adjusts the voltage
for best performance and extended
life of the battery.
When the battery's state of charge
is low, the voltage is raised slightly
to quickly bring the charge back up. When the state of charge is high,
the voltage is lowered slightly to
prevent overcharging. If the vehicle
has a voltmeter gauge or a voltage
display on the Driver Information
Center (DIC), you may see the
voltage move up or down. This is
normal. If there is a problem, an
alert will be displayed.
The battery can be discharged at
idle if the electrical loads are very
high. This is true for all vehicles.
This is because the generator
(alternator) may not be spinning fast
enough at idle to produce all of the
power needed for very high
electrical loads.
A high electrical load occurs when
several of the following are on, such
as: headlamps, high beams, rear
window defogger, climate control fan
at high speed, heated seats, engine
cooling fans, trailer loads, and loads
plugged into accessory power
outlets.
EPM works to prevent excessive
discharge of the battery. It does this
by balancing the generator's output
and the vehicle's electrical needs. It can increase engine idle speed to
generate more power whenever
needed. It can temporarily reduce
the power demands of some
accessories.
Normally, these actions occur in
steps or levels, without being
noticeable. In rare cases at the
highest levels of corrective action,
this action may be noticeable to the
driver. If so, a DIC battery voltage
and charging message displays. It is
recommended that the driver reduce
the electrical loads as much as
possible. See Driver Information
Center (DIC) (Base Level) 0 130 or
Driver Information Center (DIC)
(Uplevel) 0 133 .
Battery Power Protection This feature helps prevent the
battery from being drained, if the
interior courtesy lamps or reading
lamps are accidentally left on. If any
of these lamps are left on, they
automatically turn off after
10 minutes, if the ignition is off. The
lamps will not come back on again
until one of the following occurs:

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 .

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.

To decrease speed while the
vehicle is stopped, press SET −
until the desired set speed is
displayed.
Selecting the Follow Distance Gap
When a slower moving vehicle is
detected ahead within the selected
following gap, ACC will adjust the
vehicle's speed and attempt to
maintain the follow distance gap
selected.
Press
[ on the steering wheel to
adjust the following gap. Each press
cycles the gap button through three
settings: Far, Medium, or Near.
When pressed, the current gap
setting displays briefly on the
instrument cluster. The gap setting
will be maintained until it is
changed.
Since each gap setting corresponds
to a following time (Far, Medium,
or Near), the following distance will
vary based on vehicle speed. The
faster the vehicle speed, the further
back your vehicle will follow a
vehicle detected ahead. Consider traffic and weather conditions when
selecting the following gap. The
range of selectable gaps may not be
appropriate for all drivers and
driving conditions.
Changing the gap setting
automatically changes the alert
timing sensitivity (Far, Medium,
or Near) for the Forward Collision
Alert (FCA) feature. See Forward
Collision Alert (FCA) System 0 221 .
Alerting the Driver
If ACC is engaged, driver action
may be required when ACC cannot
apply sufficient braking because of
approaching a vehicle too rapidly.
When this condition occurs, a series
of red lights will flash on the
windshield. Either eight beeps will
sound from the front, or both sides
of the Safety Alert Seat will pulse five times. See “ Collision/Detection
Systems ” under Vehicle
Personalization 0 137 .
See Defensive Driving 0 166 .
Approaching and Following a
Vehicle
The vehicle ahead indicator is in the
instrument cluster.
The vehicle ahead indicator only
displays when a vehicle is detected
in your vehicle ’ s path moving in the
same direction.
If this indicator is not displaying,
ACC will not respond to or brake to
vehicles ahead.
ACC automatically slows the vehicle
down and adjusts vehicle speed to
follow the vehicle in front at the
selected following gap. The vehicle
speed increases or decreases to
