System Maintenance
Climate control air filter
This filter is installed behind the glove
box. It filters the dust or other pollutants
that enter the vehicle through the heating
and air conditioning system.
Have the climate control air filter
replaced by an authorized HYUNDAI
dealer according to the maintenance
schedule. If the car is being driven in
severe conditions such as dusty or rough
roads, more frequent air conditioner filter
inspections and changes are required.
If the air flow rate suddenly decreases,
the system should be checked at an
authorized HYUNDAI dealer.
Checking the amount of air conditioner refrigerant andcompressor lubricant
When the amount of refrigerant is low,
the performance of the air conditioning is
reduced. Overfilling also has a negative
influence on the air conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by an
authorized HYUNDAI dealer.
It is important that the correct type
and amount of oil and refrigerant is
used. Otherwise, damage to the com-
pressor and abnormal system opera-
tion may occur. The air conditioning system should be
serviced by an authorized HYUNDAI
dealer.

Because the refrigerant
is at very high pressure,
the air conditioning sys-
tem should only be serv-
iced by trained and cer-
tified technicians. It is important
that the correct type and amount of
oil and refrigerant is used, other-
wise damage to the vehicle and
personal injury may occur.

ature.
1. Press the AUTO button.
The modes, fan speeds, air intake and
air-conditioning will be controlled auto-
matically by the temperature setting you
select.2. Turn the temperature control knob to
the desired temperature. If the temper-
ature is set to the lowest setting (Lo),
the air conditioning system will operate
continuously. To turn the automatic operation off,
select any button of the following:

- Cooling: 3. Set the temperature control to the
desired position.
4. Set the air intake control to the outside (fresh) air position.
5. Set the fan speed control to the desired speed.
6. If air conditioning is desired, turn the air conditioning system on.
7. Press the AUTO button in order to convert to full automatic control of the
system.

will change.
Air intake control
This button is used to select the outside
(fresh) air position or recirculated air
position.
Recirculated air position
With the recirculated air position selected, air from
the passenger compart-
ment will be drawn through
the heating system and
heated or cooled according
to the function selected.
Outside (fresh) air position
With the outside (fresh) air position selected, air
enters the vehicle from out-
side and is heated or
cooled according to the
function selected.
Information
Prolonged use of the air conditioning with
the recirculated air position selected will

Fan speed control
The fan speed can be set to the desired
speed by pushing the fan speed control
button.
The higher the fan speed is, the more air
is delivered.
Pressing the OFF button turns off the
fan.
Information
For better sound quality, fan speed may
automatically slow down for a couple of
minutes when you activate voice recogni-
tion or hands free.
Air conditioning
Push the A/C button to manually turn the
system on (indicator light will illuminate)
and off.
i
Continued use of the climate con-
trol system operation in the recir-
culated air position can cause
drowsiness or sleepiness, that
may cause loss of vehicle control
resulting in an accident. Set the
air intake control to the outside
(fresh) air position as much as
possible while driving.
Continued use of the climate con-
trol system operation in the recir-
culated air position (without the
air conditioning selected) may
allow humidity to increase inside
the vehicle which may fog the
glass and obscure visibility.
Do not sleep in a vehicle with the
air conditioning or heating sys-
tem on. It may cause serious
injury or death due to a drop in
the oxygen level and/or body
temperature.

tons as long as the ignition switch is in
the ON position.
System Operation
Ventilation
1. Select the Face Level mode.
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. Select the Floor Level mode.
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 on.
If the windshield fogs up, select the Floor
& Defrost mode or press the Front
Defrost mode.
Operation Tips
To keep dust or unpleasant fumes from entering the car through the ventilation
system, temporarily set the air intake
control to the recirculated air position.
Return the control to the fresh air posi-
tion when the irritation has passed.
This will help keep the driver alert and
comfortable.
To prevent the inside of the windshield from fogging, set the air intake control
to the fresh air position and fan speed
to the desired position, turn on the air
conditioning system, and adjust the
temperature control to desired temper-
ature.

Air conditioning
All HYUNDAI Air Conditioning Systems
are filled with environmentally friendly R-
134a refrigerant.
1. Start the engine.
2. Push the air conditioning button.
3. Set the mode to the Face Level mode.
4. Set the air intake control to the recir- culated air position. However, pro-
longed operation of the recirculated air
position will excessively dry the air. In
this case, change the air position.
5. 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 con-
trol to the highest speed. When 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 can 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.
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.
After sufficient cooling has been achieved, switch back from the recircu-
lated air to the fresh outside air posi-
tion.
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 with the windows and sunroof
closed.
Use the air conditioning system every month only for a few minutes to ensure
maximum system performance.
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.
