Radio Reception
Frequency interference and static can occur during
normal radio reception if items such as cell phone
chargers, vehicle convenience accessories, and
external electronic devices are plugged into the
accessory power outlet. If there is interference or static,
unplug the item from the accessory power outlet.
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. For better radio
reception, most AM radio stations 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 signals only reach about 10 to 40 miles
(16 to 65 km). 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.
XM™ Satellite Radio Service
XM Satellite Radio Service gives digital radio reception
from coast-to-coast in the 48 contiguous United States,
and in Canada. Just as with FM, 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 XM signal for a period
of time.
Cellular Phone Usage
Cellular phone usage may cause interference with
the vehicle's 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.
Backglass Antenna
The AM-FM antenna is integrated with the rear window
defogger, located in the rear window. Make sure that
the inside surface of the rear window is not scratched
and that the lines on the glass are not damaged. If the
inside surface is damaged, it could interfere with radio
reception. For proper radio reception, the antenna
connector needs to be properly attached to the post
on the glass.
