Keep the original hand-held
transmitter for use in other vehicles
as well as for future Universal
Remote system programming. It is
also recommended that upon the
sale of the vehicle, the programmed
Universal Remote system buttons
be erased for security purposes.
See“Erasing Universal Remote
System Buttons” later in this
section.
When programming a garage door,
park outside of the garage. Park
directly in line with and facing the
garage door opener motor-head or
gate motor-head. Be sure that
people and objects are clear of the
garage door or gate being
programmed.
It is recommended that a new
battery be installed in the hand-held
transmitter for quicker and more
accurate transmission of the
radio-frequency signal.Programming the Universal
Remote System
For questions or help programming
the Universal Remote system, call
1‐800‐355‐3515 or go to
www.homelink.com.
Programming a garage door opener
involves time-sensitive actions, so
read the entire procedure before
starting. Otherwise, the device will
time out and the procedure will have
to be repeated.
To program up to three devices:
1. Hold the end of the hand-held transmitter about 3 to 8 cm
(1 to 3 in) away from the
Universal Remote system
buttons while keeping the
indicator light in view. The
hand-held transmitter was
supplied by the manufacturer of
the garage door opener receiver
(motor-head unit). 2. At the same time, press and
hold both the hand-held
transmitter button and one of the
three Universal Remote system
buttons to be used to operate
the garage door. Do not release
the Universal Remote system
button or the hand-held
transmitter button until the
indicator light changes from a
slowly to a rapidly flashing light.
You now may release both
buttons.
Some entry gates and garage
door openers may require
substitution of Step 2 with the
procedure noted in “Gate
Operator and Canadian
Programming” later in this
section.

Daytime Running
Lamps (DRL)
Daytime Running Lamps (DRL) can
make it easier for others to see the
front of your vehicle during the day.
Fully functional daytime running
lamps are required on all vehicles
first sold in Canada.
The DRL system turns on the
low-beam headlamps at a reduced
brightness. For vehicles with High
Intensity Discharge (HID)
headlamps, the dedicated DRL will
come on when all of the following
conditions are met:
.The ignition is on.
.The exterior lamps control is
in AUTO.
.The light sensor determines it is
daytime.
.The parking brake is released or
the vehicle is not in P (Park).

Black plate (3,1)Buick LaCrosse Owner Manual - 2012

This vehicle may have a DRL
disabling function. When the DRL
are on and a turn signal is activated,
the DRL on that side will be off until
the turn signal goes off.
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 located 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
Oor the ignition
is off.
Adaptive Forward
Lighting (AFL)
The Adaptive Forward Lighting
System (AFL) pivots the headlamps
horizontally to provide greater road
illumination while turning. To enable
AFL, set the exterior lamp switch to
the AUTO position. Moving the
switch out of the AUTO position
deactivates the system. AFL
operates when the vehicle speed is
greater than 3 km/h (2 mph). AFL
does not operate when the
transmission is in R (Reverse). AFL
is not immediately operable after
starting the vehicle; driving a short
distance is required to calibrate the
AFL. See Exterior Lamp Controls on
page 6‑1.

change is completed. If the lever is
briefly pressed and released, the
turn signal flashes three times.
The turn and lane‐change signal
can be turned off manually by
moving the lever back to its original
position.
If after signaling a turn or lane
change the arrow flashes rapidly or
does not come on, a signal bulb
might be burned out.
Have the bulbs replaced. If the bulb
is not burned out, check the fuse.

Lighting Features
Entry Lighting
The headlamps, taillamps, license
plate lamps, back‐up lamps, dome
lamps, and most of the interior lights
turn on briefly when the Remote
Keyless Entry (RKE)
Kbutton is
pressed, or when the door handle is
pulled on a keyless access vehicle.
See Ignition Positions (Key Access)
on page 9‑18 orIgnition Positions
(Keyless Access) on page 9‑20.
After about 30 seconds the exterior

plate lamps come on at night, or in
areas with limited lighting, when the
key is removed from the ignition.
The dome lamps also come on
when the key is removed from the
ignition. The exterior lights and
dome lamps remain on after the
door is closed for a set amount of
time, then automatically turn off.
For vehicles with keyless access,
the exterior lights and dome lamps
automatically turn on when a door is

lamps control off.
This feature can be changed. See
Vehicle Personalization on
page 5‑43.
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.
