Infotainment System 199
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 maycause 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 the
antenna 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 multi-band antenna is on the
roof of the vehicle. The antenna is
used for OnStar, the SiriusXM
Satellite Radio Service System, and
GPS (Global Positioning System),
if the vehicle has these features.
Keep the antenna clear of
obstructions for clear reception.
If the vehicle has a sunroof, and it is
open, reception can also be
affected.Items on the roof of the vehicle can
interfere with the performance of the
radio system and OnStar (if
equipped). Make sure the
multi-band antenna is not
obstructed.
