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
off. See Ignition Positions (Key
Access) on page 9‑17 orIgnition
Positions (Keyless Access) on
page 9‑19.
The exterior lights turn off
immediately by turning the
exterior lamps control to OFF.
This feature can be changed.
See Vehicle Personalization on
page 5‑39.
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.

Black plate (7,1)Buick LaCrosse Owner Manual - 2011
Lighting 6-7
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 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 displays,
it is recommended that the driver
reduce the electrical loads as much
as possible. See
Driver Information
Center (DIC) on page 5‑25.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.

Infotainment System 7-19
Radio Reception
Frequency interference and
static can occur during normal
radio reception if items such as
cellular phone chargers, vehicle
convenience accessories, and
external electronic devices are
plugged into the accessory power
outlet. If there is interference or
static, unplug the item from the
accessory power outlet.
FM
FM signals only reach about
16 to 65 km (10 to 40 mi). Although
the radio has a built-in electronic
circuit that automatically works to
reduce interference, some static
can occur, especially around tall
buildings or hills, causing the
sound to fade in and out.
AM
The range for most AM stations is
greater than for FM, especially at
night. The longer range can cause
station frequencies to interfere
with each other. For better radio
reception, most AM radio stations
boost the power levels during the
day, and then reduce these levels
during the night. Static can also
occur when things like storms and
power lines interfere with radio
reception. When this happens, try
reducing the treble on the radio.
XM™Satellite Radio Service
XM satellite radio service gives
digital radio reception from coast
to coast in the 48 contiguous
United States, and in Canada.
Just as with FM, tall buildings or
hills can interfere with satellite radio
signals, causing the sound to fade
in and out. In addition, traveling
or standing under heavy foliage,
bridges, garages, or tunnels may
cause loss of the XM signal for a
period of time.
Cellular Phone Usage
Cellular phone usage may cause
interference with the vehicle's radio.
This interference may occur when
making or receiving phone calls,
charging the phone's battery,
or simply having the phone on.
This interference can cause an
increased level of static while
listening to the radio. If static is
received while listening to the
radio, unplug the cellular phone
and turn it off.
Backglass Antenna
The AM-FM antenna is integrated
with the rear window defogger,
located in the rear window. Make
sure that the inside surface of the
rear window is not scratched and
that the lines on the glass are not
damaged. If the inside surface is
damaged, it could interfere with
radio reception. For proper radio
reception, the antenna connector
needs to be properly attached to
the post on the glass.
