2010 BUICK LACROSSE ignition

Lighting 5-3
The DRL system turns on the
low-beam headlamps at a reduced
brightness or for vehicles with
High Intensity Discharge (HID)
headlamps, the dedicated
DRL lights will come on when
the following conditions are met:
.The engine is running,
.The exterior lamp band is in
AUTO, and
.The light sensor determines it
is daytime.
When the DRL are on, the
low-beam headlamps will be on.
The taillamps, sidemarker,
instrument panel lights and other
lamps will not be on.
The DRL turn off when the
headlamps are turned to
Oor the
ignition is 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 or 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 5‑1.

Lighting Features
Entry Lighting
The headlamps, taillamps, license
plate lamps, reverse lamps, dome
lamps, and most of the interior lights
turn on briefly, when the Remote
Keyless Entry (RKE)
Kis pressed,
or when the door handle is pulled on
a Keyless Access Vehicle. See
Ignition Positions (Key Access)
on
page 8‑18or Ignition Positions
(Keyless Access)on page 8‑19.
After about 30 seconds the exterior
lamps turn off, and then the dome
and remaining interior lights will dim
to off. Entry lighting can be disabled
manually by changing the ignition
out of the OFF position, or by
pressing the Remote Keyless
Entry (RKE)
Qbutton. This feature can be activated or
deactivated in the menu SETTINGS
in the Info Display. Press CONFIG
on the infotainment system to call
up the menu. See
Vehicle
Personalization on page 4‑38.
Exit Lighting
The headlamps, taillamps, parking
lamps, reverse lamps, and license
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 a vehicle with Keyless Access,
the exterior lights and dome lamps
automatically turn on when a door is
opened after the ignition is turned

Vehicle Personalization
on page 4‑38.
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

Lighting 5-7
has a voltmeter gage 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 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 Driver Information
Center (DIC) message might be
displayed, such as BATTERY
SAVER ACTIVE, BATTERY
VOLTAGE LOW, or LOW BATTERY.
If one of these messages display, it
is recommended that the driver
reduce the electrical loads as much
as possible. See
Driver Information
Center (DIC) on page 4‑25.Battery Power Protection
The battery saver feature is
designed to protect the vehicle's
battery.
If the exterior lamps or any interior
light is left on and the ignition is
turned off, the battery rundown
protection system automatically
turns the lamp off after about
10 minutes.
