AUDIO OPERATION PRECAU-
TIONS
CAUTION
. Operate the audio system only
when the vehicle engine is run-
ning. Operating the audio system
for extended periods of time with
the engine turned off can dis-
charge the vehicle battery.
. Do not allow the system to get wet.
Excessive moisture such as spilled
liquids may cause the system to
malfunction.

RADIO

Place the ignition switch in the ACC or ON
position before turning on the radio. If you
listen to the radio with the engine not
running, the ignition switch should be
placed in the ACC position.
Radio reception is affected by station
signal strength, distance from radio trans-
mitter, buildings, bridges, mountains and
other external influences. Intermittent
changes in reception quality normally
are caused by these external influences.

Condition:
Using a cellular phone in or near the
vehicle may influence radio reception
quality.
Radio reception
Your radio system is equipped with state-
of-the-art electronic circuits to enhance
radio reception. These circuits are de-
signed to extend reception range, and to
enhance the quality of that reception.
However there are some general charac-
teristics of both AM and FM radio signals
that can affect radio reception quality in a
moving vehicle, even when the finest
equipment is used. These characteristics
are completely normal in a given recep-
tion area, and do not indicate any mal-
function in your radio system.
Reception conditions will constantly
change because of vehicle movement.
Buildings, terrain, signal distance and
interference from other vehicles can work
against ideal reception. Described below
are some of the factors that can affect
your radio reception.
Some cellular phones or other devices
may cause interference or a buzzing noise
to come from the audio system speakers.
Storing the device in a different location
may reduce or eliminate the noise.

FM radio reception
Range: the FM range is normally limited to
25 to 30 miles (40 to 48 km), with
monaural (single station) FM having
slightly more range than stereo FM. Ex-
ternal influences may sometimes interfere
with FM station reception even if the FM
station is within 25 miles (40 km). The
strength of the FM signal is directly related
to the distance between the transmitter
and receiver. FM signals follow a line-of-
sight path, exhibiting many of the same
characteristics as light. For example, they
will reflect off objects.
Fade and drift: As your vehicle moves
away from a station transmitter, the
