Antenna D300102ASA
Roof antenna (if equipped)
If your vehicle has an audio system, an
amplifying antenna is installed in your
vehicle. This antenna can be adjusted up and
down or removed from the vehicle when
needed such as washing the vehicle.AUDIO SYSTEM

CAUTION
• Before entering a place with a low
height clearance, be sure that theantenna is fully folded down or removed.
Be sure to remove the antenna before washing the car in an auto-matic car wash or it may be dam-aged.
it is important that it is fully tight-
ened to ensure proper reception.

How car audio works
AM(MW, LW) and FM radio signals are
broadcast from transmitter towers locat-
ed around your city. They are intercept-
ed by the radio antenna on your car. This
signal is then received by the radio and
sent to your car speakers.
When a strong radio signal has reached
your vehicle, the precise engineering of
your audio system ensures the best pos-
sible quality reproduction. However, in
some cases the signal coming to your
vehicle may not be strong and clear. This
can be due to factors such as the dis-
tance from the radio station, closeness of
other strong radio stations or the pres-
ence of buildings, bridges or other large
obstructions in the area. AM(MW, LW) broadcasts can be
received at greater distances than FM
broadcasts. This is because AM(MW,
LW) radio waves are transmitted at low
frequencies. These long, low frequency
radio waves can follow the curvature of
the earth rather than travelling straight
out into the atmosphere. In addition, they
curve around obstructions so that they
can provide better signal coverage.
FM broadcasts are transmitted at high
frequencies and do not bend to follow the
earth's surface. Because of this, FM
broadcasts generally begin to fade at
short distances from the station. Also,
FM signals are easily affected by build-
ings, mountains, or other obstructions.
These can result in certain listening con-
ditions which might lead you to believe a
problem exists with your radio. The fol-
lowing conditions are normal and do not
indicate radio trouble:

• Fading - As your car moves away fromthe radio station, the signal will weaken
and sound will begin to fade. When this
occurs, we suggest that you selectanother stronger station.
Flutter/Static - Weak FM signals or large obstructions between the trans-
mitter and your radio can disturb the
signal causing static or fluttering nois-
es to occur. Reducing the treble level
may lessen this effect until the distur-
bance clears. Station Swapping - As a FM signal
weakens, another more powerful sig-
nal near the same frequency may
begin to play. This is because your
radio is designed to lock onto the
clearest signal. If this occurs, selectanother station with a stronger signal.
Multi-Path Cancellation - Radio signals being received from several directions
can cause distortion or fluttering. This
can be caused by a direct and reflect-
ed signal from the same station, or by
signals from two stations with close
frequencies. If this occurs, selectanother station until the condition haspassed.
Using a cellular phone or a two-way
radio
When a cellular phone is used inside the
vehicle, noise may be produced from the
audio equipment. This does not meanthat something is wrong with the audio
equipment. In such a case, use the cellu-
lar phone at a place as far as possiblefrom the audio equipment.

CAUTION
When using a communication sys-
tem such a cellular phone or a radioset inside the vehicle, a separateexternal antenna must be fitted. When a cellular phone or a radio set
is used with an internal antenna alone, it may interfere with the vehi- cle's electrical system and adverse-
ly affect safe operation of the vehi- cle.
WARNING
Don't use a cellular phone when
you are driving. You should stop at
a safe place to use a cellular phone.
