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. 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
If equipped, SiriusXM Satellite
Radio Service provides digital radio
reception. 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.
Cell Phone Usage
Cell phone usage, such as making
or receiving phone calls, charging,
or just having the phone on may
cause static interference in the
radio. Unplug the phone or turn it off
if this happens.
Fixed Mast Antenna
The fixed mast antenna will go
through most car washes as long as
it is securely attached. If theantenna becomes slightly bent,
straighten it out by hand. If it is
badly bent, replace it.
Occasionally check that the antenna
is tight at the base. If tightening is
required, protect the paint from
damage.
Multi-Band Antenna
The roof antenna is for OnStar®,
SiriusXM®Satellite Radio, and GPS
(Global Positioning System). Keep
clear of obstructions for clear
reception. If the vehicle has a
sunroof, and it is open, reception
can also be affected.
Pandora Internet Radio
If equipped, Pandora®is a free
Internet radio service that streams
personalized radio stations based
on artists, tracks, genres, and
comedians. Create stations using
the Pandora website or Smartphone
application, then use
