Operation Tips
To keep dust or unpleasant fumes fromentering 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.

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.
