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.
Rear Side Window Antenna The AM-FM antenna is located in the passenger rear
side windows. Make sure the inside surfaces of the
rear side windows are not scratched and that the lines
on the glass are not damaged. If the inside surfaces
are damaged, they could interfere with radio reception. If a cellular telephone antenna needs to be attached to
the glass, make sure that the grid lines for the AM-FM
antenna are not damaged. There is enough space
between the grid lines to attach a cellular telephone
antenna without interfering with radio reception.
Notice: Using a razor blade or sharp object to
clear the inside of the rear side windows may affect
radio reception or damage the rear side window
antenna. Repairs would not be covered by the
warranty. Do not clear the inside of the rear side
windows with sharp objects.
Notice: Do not apply aftermarket glass tinting
with metallic lm. The metallic lm in some tinting
materials will interfere with or distort the incoming
radio reception. Any damage caused to the antenna
due to metallic tinting materials will not be covered
by the warranty.
XM™ Satellite Radio Antenna
System The XM Satellite Radio antenna is located on the roof of
the vehicle. Keep the antenna clear of obstructions for
clear radio reception.
If the vehicle has a sunroof, the performance of the XM
system may be affected if the sunroof is open.
