NOTICE
To ensure the correct audio system
operation:
Be careful not to spill beverages
over the audio system.
Do not put anything other than a
cassette tape or Compact Disc into
the slot.
The use of cellular phone inside or
near the vehicle may cause a noise
from the speakers of the audio sys-
tem which you are listening to.
However, this does not indicate a
malfunction.
RADIO RECEPTION
Usually, a problem with radio reception
does not mean there is a problem with
your radio—it is just the normal result of
conditions outside the vehicle.
For example, nearby buildings and terrain
can interfere with FM reception. Power
lines or telephone wires can interfere with
AM signals. And of course, radio signals
have a limited range, and the farther you
are from a station, the weaker its signal
will be. In addition, reception conditions
change constantly as your vehicle moves.Here are some common reception prob-
lems that probably do not indicate a prob-
lem with your radio:
FM
Fading and drifting stations—Generally, the
effective range of FM is about 40 km (25
miles). Once outside this range, you may
notice fading and drifting, which increase
with the distance from the radio transmit-
ter. They are often accompanied by distor-
tion.
Multi−path—FM signals are reflective,
making it possible for two signals to reach
your antenna at the same time. If this
happens, the signals will cancel each oth-
er out, causing a momentary flutter or
loss of reception.
Static and fluttering—These occur when
signals are blocked by buildings, trees, or
other large objects. Increasing the bass
level may reduce static and fluttering.
Station swapping—If the FM signal you
are listening to is interrupted or weak-
ened, and there is another strong station
nearby on the FM band, your radio may
tune in the second station until the origi-
nal signal can be picked up again.AM
Fading—AM broadcasts are reflected by
the upper atmosphere—especially at night.
These reflected signals can interfere with
those received directly from the radio sta-
tion, causing the radio station to sound
alternately strong and weak.
Station interference—When a reflected sig-
nal and a signal received directly from a
radio station are very nearly the same
frequency, they can interfere with each
other, making it difficult to hear the broad-
cast.
Static—AM is easily affected by external
sources of electrical noise, such as high
tension power lines, lightening, or electri-
cal motors. This results in static.
CARING FOR YOUR CASSETTE PLAYER
AND TAPES
For high performance from your cassette
player and tapes:
Clean the tape head and other parts regu-
larly.
A dirty tape head or tape path can
decrease sound quality and tangle your
cassette tapes. The easiest way to
clean them is by using a cleaning tape.
(A wet type is recommended.)

Use high−quality cassettes.
Low−quality cassette tapes can cause
many problems, including poor sound,
inconsistent playing speed, and
constant auto−reversing. They can also
get stuck or tangled in the cassette
player.
Do not use a cassette if it has been
damaged or tangled or if its label is
peeling off.
Do not leave a cassette in the player
if you are not listening to it, especially
if it is hot outside.
Store cassettes in their cases and out
of direct sunlight.
Avoid using cassettes with a total play-
ing time longer than 100 minutes (50
minutes per side). The tape used in
these cassettes is thin and could get
stuck or tangled in the cassette player.
CARING FOR YOUR COMPACT DISC
PLAYER AND DISCS
Use only compact discs labeled as
shown.
Extremely high temperatures can keep
your compact disc player from working.
On hot days, use the air conditioning
to cool the vehicle interior before you
listen to a disc.
Bumpy roads or other vibrations may
make your compact disc player skip.
If moisture gets into your compact disc
player, you may not hear any sound
even though your compact disc player
appears to be working. Remove the
disc from the player and wait until it
dries.

Your automatic changer or compact
disc player cannot play special shaped
or low−quality compact discs such as
those shown here. Do not use them as
the changer or player could be dam-
aged.
Handle compact discs carefully, espe-
cially when you are inserting them.
Hold them on the edge and do not
bend them. Avoid getting fingerprints
on them, particularly on the shiny side.
Dirt, scrapes, warping, pin holes, or
other disc damage could cause the
player to skip or to repeat a section of
a track. (To see a pin hole, hold the
disc up to the light.)
Remove discs from the compact disc
player when you are not listening
to them. Store them in their plastic
cases away from moisture, heat, and
direct sunlight.
To clean a compact disc: Wipe it with a
soft, lint−free cloth that has been damp-
ened with water. Wipe in a straight line
from the center to the edge of the disc
(not in circles). Dry it with another soft,
lint−free cloth. Do not use a conventional
record cleaner or anti−static device.
CAUTION
Compact disc players use an invisible
laser beam which could cause hazard-
ous radiation exposure if directed
outside the unit. Be sure to operate
the player correctly.
