Infotainment System
127
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
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 the Navigation System,
OnStar and the SiriusXM Satellite
Radio Service System if the vehicle
has these features. Tall buildings,
hills, trees, heavy foliage, tunnels,
bridges, and garages will affect
reception. Keep the antenna clear of
obstructions for clear reception.
Make sure there is sufficient
clearance when entering garages or
parking structures.
Audio Players
Avoiding Untrusted Media
Devices
When using media devices such as
CDs, DVDs, Blu-ray Discs, SD
cards, USB devices, and mobile
devices, consider the source.
Untrusted media devices could
contain files that affect system
operation or performance. Avoid use
if the content or origin cannot be
trusted.
CD Player
Care of the CD Player
Do not add any label to a CD.
It could get caught in the CD player.
If a CD is recorded on a personal
computer and a description label is
needed, try labeling the top of the
recorded CD with a marking pen.
The use of CD lens cleaners is not
advised, due to the risk of
contaminating the lens of the CD
optics with lubricants internal to the
CD player mechanism.
