Radio Reception
You may experience frequency interference and static
during normal radio reception if items such as cellphone
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.
3-84

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 will 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 your radio.
FM Stereo
FM stereo will give the best sound, but FM signals
will reach only about 10 to 40 miles (16 to 65 km).
Tall buildings or hills can interfere with FM signals,
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 (if available). 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
XM signal for a period of time. The radio may display
NO XM SIGNAL to indicate interference.
Cellular Phone Usage
Cellular phone usage may cause interference with your
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
is 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.

Care of Your CDs
Handle CDs carefully. Store them in their original cases
or other protective cases and away from direct
sunlight and dust. The CD player scans the bottom
surface of the disc. If the surface of a CD is damaged,
such as cracked, broken, or scratched, the CD will
not play properly or not at all. If the surface of a CD is
soiled, take a soft, lint free cloth or dampen a clean,
soft cloth in a mild, neutral detergent solution mixed
with water, and clean it. Make sure the wiping process
starts from the center to the edge.
Do not touch the bottom side of a CD while handling
it; this could damage the surface. Pick up CDs by
grasping the outer edges or the edge of the hole
and the outer edge.
Care of the CD Player
The use of CD lens cleaners for CD players is not
advised, due to the risk of contaminating the internal
lens of the CD optics with lubricants.
Diversity Antenna System
The AM-FM antennas are located under the decklid
surface in the trunk compartment. the antennas
are hidden from view and are not accessible.
If adding an aftermarket cellular telephone to your
vehicle, do not attach the antenna to the rear glass.
This would interfere with the convertible top retraction
operation and could cause damage to the
nished/painted surfaces.
XM™ Satellite Radio Antenna
System (Trunk Mounted)
Your vehicle may have the XM™ Satellite Radio
antenna that is located on the trunk of your vehicle.
Keep this antenna clear of snow and ice build up
for clear radio reception.
XM™ Satellite Radio Antenna
System (Diversity System)
Your vehicle may have the XM™ Satellite Radio
antennas that are located in the outside rear view
mirrors. These antennas are hidden from view and
are not accessible.
