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
16 to 65 km (10 to 40 mi). 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.

Fixed Mast Antenna
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.
Occasionally check to make sure
the antenna is tightened to its base.
If tightening is required, tighten
by hand until fully seated plus
one quarter turn.
Satellite Radio Antenna
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
(if equipped) may be affected if the
sunroof is open.
Audio Players
CD Player
Care of the CD Player
Do not add any label to a CD.
It could get caught in the CD. 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.
Notice:If a label is added to a
CD, more than one CD is inserted
into the slot at a time, or an
attempt is made to play scratched
or damaged CDs, the CD player
could be damaged. While using
the CD player, use only CDs in
good condition without any label,
load one CD at a time, and keep the CD player and the loading slot
free of foreign materials, liquids,
and debris.
If an error displays, see
“CD Player
Messages” later in this section.Care of CDs
If playing a CD-R, the sound quality
can be reduced due to CD-R or
CD-RW quality, the method of
recording, the quality of the music
that has been recorded, and the
way the CD-R or CD-RW has been
handled. Handle them carefully.
Store CD-Rs or CD-RWs 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 does not play properly or not
at all. 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.
