Radio 13
Radio Reception
Unplug electronic devices from the
accessory power outlets if there is
interference or static in the radio.
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.
Mobile Device Usage
Mobile device usage, such as
making or receiving calls, charging,
or just having the mobile device on
may cause static interference in the
radio. Unplug the mobile device or
turn it off if this happens.
Multi-Band Antenna
The roof antenna is for OnStar 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.
