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

Black plate (13,1)Buick LaCrosse Owner Manual - 2013 - crc - 9/7/12
Infotainment System 7-13
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.
SiriusXM®Satellite Radio
Service
SiriusXM 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 SiriusXM 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 in the
rear window. Do not scratch the
inside surface or damage the lines
in the glass. 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.
If attaching a cell phone antenna to
the glass, attach it between the grid
lines.
Notice:
Using a razor blade or
sharp object to clear the inside
rear window can damage the rear
window antenna and/or the rear
window defogger. Repairs would
not be covered by the vehicle
warranty. Do not clear the inside
rear window with sharp objects.
Notice: Do not apply aftermarket
glass tinting with metallic film.
The metallic film in some tinting
materials will interfere with or
distort the incoming radio
reception. Any damage caused to
the backglass antenna due to
metallic tinting materials will not
be covered by the vehicle
warranty.

Driving and Operating 9-9
WARNING (Continued)
cannot be seen or smelled. It can
cause unconsciousness and even
death.
If the vehicle is stuck in the snow:
.Clear away snow from around
the base of your vehicle,
especially any that is blocking
the exhaust pipe.
.Check again from time to
time to be sure snow does
not collect there.
.Open a window about 5 cm
(2 in) on the side of the
vehicle that is away from the
wind to bring in fresh air.
.Fully open the air outlets on
or under the instrument
panel.
.Adjust the climate control
system to a setting that
circulates the air inside the
vehicle and set the fan speed(Continued)
WARNING (Continued)
to the highest setting. See
“Climate Control Systems” in
the Index.
For more information about
carbon monoxide, see Engine
Exhaust on page 9‑26.
To save fuel, run the engine for only
short periods as needed to warm
the vehicle and then shut the engine
off and close the window most of
the way to save heat. Repeat this
until help arrives but only when you
feel really uncomfortable from the
cold. Moving about to keep warm
also helps.
If it takes some time for help to
arrive, now and then when you run
the engine, push the accelerator
pedal slightly so the engine runs
faster than the idle speed. This
keeps the battery charged to restart
the vehicle and to signal for help
with the headlamps. Do this as little
as possible to save fuel.
If the Vehicle Is Stuck
Slowly and cautiously spin the
wheels to free the vehicle when
stuck in sand, mud, ice, or snow.
If stuck too severely for the traction
system to free the vehicle, turn the
traction system off and use the
rocking method. See Traction
Control System (TCS) on
page 9‑34.
{WARNING
If the vehicle's tires spin at high
speed, they can explode, and you
or others could be injured. The
vehicle can overheat, causing an
engine compartment fire or other
damage. Spin the wheels as little
as possible and avoid going
above 56 km/h (35 mph).
