CAUTION:
o Use the power outlets only when the
engine is running and remove the plug
from the power outlet after using the
electric device. Using the power outlets
when the engine stops or keeping the
electric device plugged in for many hours
may cause the battery to discharge.
o Do not use the power outlet to connect
electric accessories or equipment that
are not designed to operate on 12 volts.
o Some electronic devices can cause elec-
tronic interference when plugged into
the power outlet. These devices may
cause excessive audio noise and mal-
functions in other electronic systems or
devices in your vehicle.

WARNING:
o If you open the fuel filler cap during high
ambient temperatures, a slight "pres-
sure sound" may be heard. This is nor-
mal and not a cause for concern.
Whenever you open the fuel filler cap,
turn it slowly.
o Make sure the fuel filler cap is replaced
and securely seated after fueling. Failure
to replace or fully seat the fuel filler cap
will result in fuel vapors escaping into
the atmosphere and the check engine
" " indicator illuminating.
o Do not "TOP-OFF" after the first nozzle
shut off when refueling.
o Automotive fuels are flammable/explo-
sive materials. When refueling, please
note the following guidelines carefully.
- Before touching the fuel nozzle or fuel
filler cap, have one's hands in contact
with metal parts away from the filler
neck to discharge static electricity.
!
!
WARNING:
o The fuel cap must be tightened until the
cap clicks, otherwise " " light will
illuminate.
o Gasoline vapors are dangerous. Before
refueling, always stop the engine and
never allow sparks or open flames near
the filler area. If you need to replace the
filler cap, use a genuine Hyundai re-
placement part.

!
WARNING:
- Do not get back in the vehicle while
refueling. Do not operate anything that
can produce static electricity. Static
electricity discharge can ignite fuel
vapors resulting in an explosion.
- When using a portable fuel container,
be sure to place the container on the
ground while refueling. Static electric-
ity discharge from the container can
ignite fuel vapors causing a fire. While
starting refueling, contact should be
maintained until the filling is complete.
- Do not use cellular phones around a
gas station. The electric current or elec-
tronic interference from cellular phones
can ignite fuel vapors causing a fire.
- When refueling, always turn the engine
off. Sparks by engine compartment
electrical equipment can ignite fuel
vapors causing a fire. After refueling,
check to make sure the fuel filler cap is
securely closed, and then start the
engine.
- Do not smoke or try to light cigarettes
around a gas station. Automotive fuels
are flammable.

WARNING:
o Keep the cruise control ON/OFF switch
off when not using the cruise control.
o Use the cruise control system only when
traveling on open highways in good
weather.
o Do not use the cruise control when it
may not be safe to keep the car at a
constant speed, for instance, driving in
heavy or varying traffic, or on slippery
(rainy, icy or snow-covered) or winding
roads or over 6% up-hill or down-hill
roads.
o Pay particular attention to the driving
conditions whenever using the cruise
control system.
o During cruise-speed driving of a manual
transaxle vehicle, do not shift into neu-
tral without depressing the clutch pedal,
since the engine will be overrevved. If
this happens, depress the clutch pedal
or release the cruise control ON/OFF
switch.
o During normal cruise control operation,
when the "SET" switch is activated or
reactivated after applying the brakes,
the cruise control will energize after ap-
proximately 3 seconds. This delay is
normal.

B740C02O-AATDe-Humidified HeatingFor dehumidified heating:
o Set the air flow control to the face ( ) position.
o Turn on the air conditioning switch. The air
conditioning indicator light should come on at
the same time.
o Set the air intake control to the fresh air ( )
position.
o Adjust the fan control to the desired speed.
o For more rapid action, set the fan at one of
the higher speeds.
o Adjust the temperature control to provide the
desired amount of warmth.
B740C01NF-A
B740D02Y-AATOperation Tipso If the interior of the car is hot when you first
get in, open the windows for a few minutes
to expel the hot air.
o When you are using the air conditioning
system, keep all windows closed to keep hot
air out.
o When moving slowly, as in heavy traffic, shift
to a lower gear. This increases engine speed,
which in turn increases the speed of the air
conditioning compressor.
o On steep grades, turn the air conditioning off
to avoid the possibility of the engine over-
heating.
o During winter months or in periods when the
air conditioning is not used regularly, run the
air conditioning once every month for a few
minutes. This will help circulate the lubri-
cants and keep your system in peak oper-
ating condition.

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:o It should be noted that prolonged opera-
tion of the heating system in "recircula-
tion" mode will give rise to fogging 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 "Re-
circulation" mode selected may result in
the air within the passenger compart-
ment becoming excessively dry.
o When the ignition switch is turned "ON"
the air intake control will change to " "
mode (regardless of switch position).
This is normal operation. The air intake
control operates in "AUTO" mode when
turning the ignition to the ON position if
the "AUTO" mode was used before shut-
ting off the engine.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:o It should be noted that prolonged opera-
tion of the heating system in recircula-
tion mode ( ) will give rise to misting
of the windshield and side windows and
the air within the passenger compart-
ment will become stale. In addition, pro-
longed use of the air conditioning with
the recirculation mode ( ) sele-cted
may result in the air within the passenger
compartment becoming excessively dry.
o When the ignition switch is turned "ON",
the air intake control will change to
"Fresh" mode (regardless of switch po-
sition). This is normal operation. The air
intake control operates in "AUTO" mode
when turning the ignition to the ON
position if the "AUTO" mode was used
before shutting off the engine.

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
