A070A01A-AATCAUTION: MODIFICATIONS TO YOUR HYUNDAI
Your Hyundai should not be modified in any way. Such modifications may adversely affect the performance, safety
or durability of your Hyundai and may, in addition, violate conditions of the limited warranties covering the vehicle.
Certain modifications may also be in violation of regulations established by the U.S. Department of Transportation
and other federal or state agencies.
A080A01S-AATTWO-WAY RADIO OR CELLULAR TELEPHONE INSTALLATION
Your vehicle is equipped with electronic fuel injection and other electronic components. It is possible for an
improperly installed/adjusted two-way radio or cellular telephone to adversely affect electronic systems. For this
reason, we recommend that you carefully follow the radio manufacturer's instructions or consult your Hyundai
dealer for precautionary measures or special instructions if you choose to install one of these devices.

FM broadcasts are transmitted at high frequen-
cies and do not bend to follow the earth's
surface. Because of this, FM broadcasts gen-
erally begin to fade at short distances from the
station. Also, FM signals are easily affected by
buildings, mountains, or other obstructions.
These can result in certain listening conditions
which might lead you to believe a problem exists
with your radio. The following conditions are
normal and do not indicate radio trouble: AM broadcasts can be received at greater
distances than FM broadcasts. This is because
AM radio waves are transmitted at low frequen-
cies. 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.

How Car Audio Works
AM and FM radio signals are broadcast from
transmitter towers located around your city.
They are intercepted 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 possible quality repro-
duction. 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
distance from the radio station, closeness of
other strong radio stations or the presence of
buildings, bridges or other large obstructions in
the area.Ionosphere

o Station Swapping - As an FM signal weak-
ens, another more powerful signal near the
same frequency may begin to play. This is
because your radio is designed to lock onto
the clearest signal. If this occurs, select
another station with a stronger signal.
o Multi-Path Cancellation - Radio signals being
received from several directions can cause
distortion or fluttering. This can be caused by
a direct and reflected signal from the same
station, or by signals from two stations with
close frequencies. If this occurs, select
another station until the condition has passed. o Fading - As your car moves away from the
radio station, the signal will weaken and
sound will begin to fade. When this occurs,
we suggest that you select another stronger
station.
o Flutter/Static - Weak FM signals or large
obstructions between the transmitter and
your radio can disturb the signal causing
static or fluttering noises to occur. Reducing
the treble level may lessen this effect until the
disturbance clears.

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 equip-
ment. This does not mean that something is
wrong with the audio equipment. In such a case,
use the cellular phone at a place as far as
possible from the audio equipment.
CAUTION:When using a communication system such
a cellular phone or a radio set inside the
vehicle, a separate external antenna must
be fitted. When a cellular phone or a radio
set is used with an internal antenna alone,
it may interfere with the vehicle's electrical
system and adversely affect safe operation
of the vehicle.
WARNING:Don't use a cellular phone when you are
driving. Stop at a safe place to use a cellular
phone.
