Exterior Lighting Exterior Lamp Controls
The exterior lamp control is on the
instrument panel on the outboard
side of the steering wheel.
Turn the control to the following
positions:
O : Turns off the exterior lamps.
The knob returns to the AUTO
position after it is released. Turn to
O again to reactivate the
AUTO mode.

Lighting 145AUTO : Automatically turns the
exterior lamps on and off,
depending on outside lighting.
; : Turns on the parking lamps,
including all lamps, except the
headlamps.
2 : Turns on the headlamps
together with the parking lamps and
instrument panel lights.
IntelliBeam System If equipped, this system turns the
vehicle's high-beam headlamps on
and off according to surrounding
traffic conditions.
The system turns the high-beam
headlamps on when it is dark
enough and there is no other traffic
present.
This light
b comes on in the
instrument cluster when the
IntelliBeam system is enabled. Turning On and Enabling
IntelliBeam
To enable the IntelliBeam system,
with the turn signal lever in the
neutral position, turn the exterior
lamp control to AUTO.
Driving with IntelliBeam
The system only activates the high
beams when driving over 40 km/h
(25 mph).
The blue high-beam on light
appears on the instrument cluster
when the high beams are on.
There is a sensor near the top
center of the windshield that
automatically controls the system.
Keep this area of the windshield
clear of debris to allow for best
system performance.
The high-beam headlamps remain
on, under the automatic control,
until one of the following situations
occurs:
.
The system detects an
approaching vehicle's
headlamps. .
The system detects a preceding
vehicle's taillamps.
.
The outside light is bright
enough that high-beam
headlamps are not required.
.
The vehicle's speed drops below
20 km/h (12 mph).
.
The IntelliBeam system is
disabled by the high/low-beam
changer or the flash-to-pass
feature. If this happens, the high/
low-beam changer must be
activated two times within
two seconds to reactivate the
IntelliBeam system. The
instrument cluster light will come
on to indicate the IntelliBeam
system is reactivated. See
Headlamp High/Low-Beam
Changer 0 146 and
Flash-to-Pass 0 146 .
The high beams may not turn off
automatically if the system cannot
detect another vehicle's lamps
because of any of the following:

The other vehicle's lamps are
missing, damaged, obstructed
from view, or otherwise
undetected.
.
The other vehicle's lamps are
covered with dirt, snow, and/or
road spray.
.
The other vehicle's lamps cannot
be detected due to dense
exhaust, smoke, fog, snow, road
spray, mist, or other airborne
obstructions.
.
The vehicle's windshield is dirty,
cracked, or obstructed by
something that blocks the view
of the light sensor.
.
The vehicle is loaded such that
the front end points upward,
causing the light sensor to aim
high and not detect headlamps
and taillamps.
.
Driving on winding or hilly roads.
The automatic high-beam
headlamps may need to be disabled
if any of the above conditions exist. Exterior Lamps Off
Reminder A warning chime sounds if the driver
door is opened while the ignition is
off and the exterior lamps are on.

Low-Beam Changer
3 : Push the turn signal lever away
from you and release, to turn the
high beams on. To return to low
beams, push the lever again or pull
it toward you and release.
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 toward you, and
release.
Daytime Running
Lamps (DRL) DRL can make it easier for others to
see the front of the vehicle during
the day. Fully functional DRL are
required on all vehicles first sold in
Canada.
The DRL system comes on when
the following conditions are met:
.
The ignition is on.
.
The exterior lamp control is
in AUTO.
.
The transmission is not in
P (Park).
.
The light sensor determines it is
daytime.
When the DRL system is on, only
the DRL are on. The taillamps,
sidemarker lamps, instrument panel
lights, and other lamps will not
be on.

Lighting 147When it begins to get dark, the
automatic headlamp system
switches from DRL to the
headlamps.
To turn off the DRL, turn the exterior
lamp control to
O and then release.
For vehicles first sold in Canada, off
will only work 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.
When it is bright enough outside,
the headlamps will turn off or may
change to Daytime Running
Lamps (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
lamps coming on varies based on
wiper speed. When the wipers are
not operating, these lamps turn off.
Move the exterior lamp control to
Oor

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 0 133 .
Battery Load
Management The vehicle has Electric Power
Management (EPM), which
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.

Buick Envision Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
13555857) - 2020 - CRC - 2/25/19
Lighting 151When the state of charge is high,
the voltage is lowered slightly to
prevent overcharging. The voltmeter
gauge or the voltage display on the
Driver Information Center (DIC),
if equipped, may show the voltage
moving 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 the
power that is needed for very high
electrical loads.
A high electrical load occurs when
several of the following are on, such
as: headlamps, high beams, fog
lamps, 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 message might
be displayed and it is recommended
that the driver reduce the electrical
loads as much as possible.
Battery Power Protection The battery saver feature is
designed to protect the vehicle's
battery.
If some interior lamps are left on
and the ignition is turned off, the
battery rundown protection system
automatically turns the lamp off after
some time. Exterior Lighting Battery
Saver The exterior lamps turn off about
10 minutes after the ignition is
turned off, if the parking lamps or
headlamps have been manually left
on. This protects against draining
the battery. To restart the 10-minute
timer, turn the exterior lamp control
to the
O position and then back to
the
; or
2 position.
To keep the lamps on for more than
10 minutes, the ignition must be on
or in ACC/ACCESSORY.
