Infotainment System 7-11
boost the power levels during the
day, and then reduce these levels
during the night. 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.
FM Stereo
FM stereo gives the best sound, but
FM signals reach only about 16 to
65 km (10 to 40 mi). Tall buildings or
hills can interfere with FM signals,
causing the sound to fade in
and out.
Cellular Phone Usage
Cellular phone usage may cause
interference with the radio. This
interference may occur when
making or receiving phone calls,
charging the phone's battery,
or simply having the phone on. This
interference causes an increased
level of static while listening to the
radio. If static is received while
listening to the radio, unplug the
cellular phone and turn it off.
Fixed Mast Antenna
(Multi-Band)
The multi-band antenna is on the
roof of the vehicle. The antenna is
used for OnStar
®and the SiriusXM®
Satellite Radio Service System if the
vehicle has these features. Keep
the antenna clear of obstructions for
clear reception. Make sure there is
sufficient clearance when entering
garages or parking structures.
Fixed Mast
Antenna (Care)
The fixed mast antenna can
withstand most car washes without
being damaged as long as it is
securely attached to the base. If the
mast becomes slightly bent,
straighten it out by hand. If the mast
is badly bent, replace it.
Make sure there is sufficient
clearance when entering garages or
parking structures.
Occasionally check to make sure
the antenna is tightened to its base.
If tightening is required, tighten
by hand.
