System operation
Ventilation
1. Set the mode to the position.
2. Set the air intake control to the outside
(fresh) air position.
3. Set the temperature control to the
desired position.
4. Set the fan speed control to the
desired speed.
Heating
1. Set the mode to the position.
2. Set the air intake control to the outside
(fresh) air position.
3. Set the temperature control to the
desired position.
4. Set the fan speed control to the
desired speed.
5. If dehumidified heating is desired, turn
the air conditioning system (if
equipped) on.
If the windshield fogs up, set the mode
to the
,position.Operation Tips
To prevent dust or unpleasant fumes
from entering the vehicle through the
ventilation system, temporarily set the
air intake control to the recirculated air
position. Be sure to return the control
to the fresh air position when the irrita-
tion has passed to keep fresh air in the
vehicle. This will help keep the driver
alert and comfortable.
Air for the heating/cooling system is
drawn in through the grilles just ahead
of the windshield. Care should be
taken that these are not blocked by
leaves, snow, ice or other obstructions.
To prevent interior fog on the wind-
shield, set the air intake control to the
fresh air position and fan speed to the
desired position, turn on the air condi-
tioning system, and adjust the temper-
ature control to desired temperature.
Air conditioning
All HYUNDAI Air Conditioning Systems
are filled with environmentally friendly
R-134a refrigerant which does not dam-
age the ozone layer.
1. Start the engine. Push the air condi-
tioning button.
2. Set the mode to the position.
3. Set the air intake control to the recir-
culated air position. However, pro-
longed operation of the reticulated air
position will excessively dry the air. In
this case, change the air position.
4. Adjust the fan speed control and tem-
perature control to maintain maximum
comfort.
When maximum cooling is desired, set
the temperature control to the extreme
left position then set the fan speed
control to the highest speed.

NOTICE
• While using the air conditioning sys-
tem, monitor the engine temperature
gauge closely while driving up hills or
in heavy traffic when outside temper-
atures are high. Air conditioning sys-
tem operation may cause engine over-
heating. Continue to use the blower
fan but turn the air conditioning sys-
tem off if the engine temperature
gauge indicates engine overheating.
• Opening the windows in humid
weather while air conditioning oper-
ates may create water droplets inside
the vehicle. Since excessive water
droplets may cause damage to electri-
cal equipment, air conditioning
should only be used with the windows
closed.
Air conditioning system operation tips
If the vehicle has been parked in direct
sunlight during hot weather, open the
windows for a short time to let the hot
air inside the vehicle escape.
To help reduce moisture inside of the
windows on rainy or humid days,
decrease the humidity inside the vehi-
cle by operating the air conditioning
system.
During air conditioning system opera-
tion, you may occasionally notice a
slight change in engine speed as the
air conditioning compressor cycles.
This is a normal system operation
characteristic.
Use the air conditioning system every
month only for a few minutes to ensure
maximum system performance.
When using the air conditioning sys-
tem, you may notice clear water drip-
ping (or even puddling) on the ground
under the passenger side of the vehi-
cle. This is a normal system operation
characteristic. Operating the air conditioning system
in the recirculated air position provides
maximum cooling, however, continual
operation in this mode may cause the
air inside the vehicle to become stale.
During cooling operation, you may
occasionally notice a misty air flow
because of rapid cooling and humid air
intake. This is a normal system opera-
tion characteristic.
If you operate air conditioner exces-
sively, the difference between the tem-
perature of the outside air and that of
the windshield could cause the outer
surface of the windshield to fog up,
causing loss of visibility. In this case,
set the mode selection knob or button
to the position and fan speed con-
trol to the lower speed.

Defogging logic
To reduce the probability of fogging up
the inside of the windshield, the air intake
is controlled automatically according to
certain conditions such as or
position. To cancel or return the defog-
ging logic, perform the following steps.
Automatic climate control system
1. Turn the engine start/stop button to the
ON position.
2. Select the defrost position pressing
defrost button ( ).
3. While holding the air conditioning but-
ton (A/C) pressed, press the air intake
control button at least 5 times within 3
seconds.
The indicator on the air intake control
button blinks 3 times with 0.5 second of
interval. It indicates that the defogging
logic is canceled or returned to the pro-
grammed status.If the battery has been discharged or dis-
connected, the system resets to the pro-
grammed defogging logic.

How vehicle 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 vehicle. This signal
is then received by the radio and sent to
your vehicle 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.
