B970C01NF-AATAutomatic OperationThe FATC (Full Automatic Temperature Con-
trol) system automatically controls heating and
cooling as follows:
1. Push the "AUTO" switch. The indicator light
will illuminate confirming that the Face, Floor
and/or Bi-Level modes as well as the blower
speed and air conditioner will be controlled
automatically.
And, the air conditioning will operate if ambi-
ent temperature is higher than 34.7°F(1.5°C)
and automatically turns off if the ambient
temperature drops below 33.08°F(0.6°C).2. Turn the "TEMP" knob to set the desired
temperature.
The temperature will increase to the maxi-
mum "HI" by turning the knob clockwise.
The temperature will decrease to the mini-
mum "LO" by turning the knob counter-
clockwise.
NOTE:If the battery has been discharged or dis-
connected, the temperature mode will reset
to Centigrade degrees.
This is a normal condition and you can
change the temperature mode from Centi-
grade to Fahrenheit as follows;
Press the "OFF" and "AUTO " button simul-
taneously for 3 seconds.
The display shows that the unit of tempera-
ture is adjusted to Centigrade or Fahrenheit

With the "Fresh" mode selected, air enters the
vehicle from the outside and is heated or cooled
according to the function selected.
With the "Recirculation" mode selected, air from
within the passenger compartment will be drawn
through the heating system and heated or
cooled according to the function selected.
NOTE:It should be noted that prolonged opera-
tion of the heating system in "recirculation"
mode will give rise to fogging of the wind-
shield and side windows and the air within
the passenger compartment will become
stale. In addition, prolonged use of the air
conditioning with the "Recirculation" mode
selected may result in the air within the
passenger compartment becoming exces-
sively dry.Recirculation mode :
Air from witin the passenger compartment will
be drawn through the heating system and heated
or cooled according to the function selected.
Exhaust gas cutoff mode :
Air enters the vehicle from the outside.
But if exhaust gas enters the vehicle from the
outside, the exhaust gas cutoff mode ( ) is
automatically converted to the ( ) mode, to
prevent exhaust gas from entering the vehicle.
NOTE:It should be noted that prolonged opera-
tion of the heating system in recirculation
mode (
) will give rise to misting of the
windshield and side windows and the air
within the passenger compartment will
become stale. In addition, prolonged use of
the air conditioning with the recirculation
mode ( ) sele-cted may result in the air
within the passenger compartment becom-
ing excessively dry.

STEREO SOUND SYSTEMB750A02A-AATHow Car Audio Works
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. 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.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: Ionosphere

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.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.
B750B05Y-AATUsing a cellular phone or a two-way radioWhen 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.
WARNING:
Hyundai recommends that you never use a
cell phone while driving. This could result
in loss of control, and an accident that may
cause death, serious injury, or property
damage. You must stop at a safe place to
use a cellular phone.NOTE:Some states and cities have regulations
prohibiting the use of cell phones while
driving. You should be aware of the specific
requirements in your area.
