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. Some cellular services
may interfere with SXM
reception causing loss of
signal.
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 may be used
for radio, navigation, and other
communication systems,
depending on the equipped
options. Keep clear of
obstructions for clear
reception. If the vehicle has a
sunroof, and it is open,
reception can also be affected.
