ation of the heating in recirculated air
position will cause 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 recirculated air
position selected, will result in excessive-
ly dry air in the passenger compart-
ment. WARNING
• Continued use of the climate con-
trol system operation in the recir-
culated air position may allow
humidity to increase inside vehi-
cle which may fog the glass and
obscure visibility.
Do not sleep in a vehicle with air conditioning or heating system
on. It may cause serious harm or
death due to a drop in the oxygen
level and/or body temperature.
Continued use of the climate con- trol system operation in the recir-
culated air position can cause
drowsiness or sleepiness, and
loss of vehicle control. Set the air
intake control to the outside
(fresh) air position as much as
possible while driving.

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.
Be sure to return the control to the
fresh air position when the irritation
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 temperature
control to desired temperature.
Air conditioning (if equipped)
All Hyundai Air Conditioning Systems are
filled with environmentally friendly
R-134a refrigerant which is not damag-
ing to 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 outside air or recirculated 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, set the mode control to
the MAX A/C position, then set the fan
speed control to the highest speed.✽ ✽ NOTICE
• When using the air conditioning sys-
tem, monitor the temperature gauge
closely while driving up hills or in
heavy traffic when outside tempera-
tures 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 temperature gauge indi-
cates engine overheating.
• When opening the windows in humid weather air conditioning may create
water droplets inside the vehicle.
Since excessive water droplets may
cause damage to electrical equipment,
air conditioning should only be run
with the windows closed.

Air conditioning system operation tips
If the vehicle has been parked in directsunlight 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 win- dows on rainy or humid days, decrease
the humidity inside the vehicle by oper-
ating 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, even if only for a few minutes,
to ensure maximum system perform-
ance.
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 does
provide maximum cooling, however,
continual operation in this mode may
cause the air inside the vehicle to
become stale.
Climate control air filter
(if equipped)
The climate control air filter installed
behind the glove box, filters the dust or
other pollutants that come into the vehi-
cle from the outside through the heating
and air conditioning system. If dust or
other pollutants accumulate in the filter
over a period of time, the air flow from the
air vents may decrease, resulting in
moisture accumulation on the inside of
the windshield even when the outside
(fresh) air position is selected. If this hap-
pens, have the climate control air filter
replaced by an authorized Hyundai deal-
er.

controlled by simply setting the desired
temperature.
The Full Automatic Temperature Control
(FATC) system automatically controls the
heating and cooling system as follows;
1. Push the AUTO button. It is indicated
by AUTO on the display. The modes,
fan speeds, air intake and air-condi-
tioning will be controlled automatically
by temperature setting. 2. Push the TEMP button to set the
desired temperature.
If the temperature is set to the lowest
setting LO, the air conditioning system
will operate continuously.
3. To turn the automatic operation off, press any button except temperature
control button. If you press the mode
selection button, air-conditioning but-
ton, defrost button, air intake control
button or fan speed button, the select-
ed function will be controlled manually
while other functions operate automat-
ically.
Regardless of the temperature setting,
when using automatic operation, the air
conditioning system can automatically
turn on to decrease the humidity inside
the vehicle, even if the temperature is set
to warm.
