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

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 multi-band roof antenna
may be used for radio,
navigation, and other
communication systems,
depending on the equipped
options. To ensure clear
reception, keep the antenna
clear of obstructions, such as
snow and ice. If the vehicle has
a sunroof, and it is open, or a
roof loaded with cargo,
reception may be affected.
