3. “MODE” button
Push the “MODE” button to select an
audio mode. Each time you push this
button, the system changes between the
radio, cassette tape player and compact
disc player.
To turn the audio system on, push the
“MODE” button.
To turn the audio system off, push and
hold the “MODE” button until the system
turns off.
NOTICE
To ensure the correct audio system
operation:
Be careful not to spill beverages
over the 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 system
which you are listening to. Howev-
er, this does not indicate a mal-
function.
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. 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
problem 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 in-
crease with the distance from the radio
transmitter. They are often accompanied
by distortion.
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
other 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 inter-
fere with those received directly from the
radio station, causing the radio station to
sound alternately strong and weak.
Station interference—When a reflected
signal 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
broadcast.
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 the best performance for your cas-
sette player and tapes:
Clean the tape head and other parts reg-
ularly.
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 cas-
sette 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
playing 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
Your compact disc player is intended
for use with 12 cm (4.7 in.) discs only.
Extremely high temperatures can keep
your compact disc player from work-
ing. On hot days, use the air condi-
tioning to cool the vehicle interior be-
fore you use the players.
Bumpy roads or other vibrations may
make your compact disc player skip.
If moisture gets into your compact
disc player, the players may not play
even though they appear to be wor-
king. Remove the disc from the player
and wait until it dries.
