Mode selection
The mode selection knob control the
direction of the air flow through the venti-lation system.
Air can be directed to the floor, dashboard
outlets, or windshield. Six symbols are used
to represent MAX A/C, Face, Bi-Level,
Floor, Floor-Defrost and Defrost air position. The MAX A/C mode is used to cool the
inside of the vehicle faster.MAX A/C-Level (B,D)

and face. Additionally, each outlet can becontrolled to direct the air dischargedfrom the outlet.
Bi-Level (B, D, C, E)
Air flow is discharged towards the face
and floor.
Floor-Level (C, E, A, D)
Most of the air flow is directed to the
floor, with a small amount of the air beingdirected to the windshield and side win-
dow defroster.

Instrument panel vents
The outlet port can be opened or closed
separately using the horizontal thumb-
wheel. To close the vent, rotate it left to
the maximum position. To open the vent,
rotate it right to the desired position.
Also, you can adjust the direction of air
delivery from these vents using the vent
control lever as shown. D230102AFD
Temperature control
The temperature control knob allows you
to control the temperature of the air flow-
ing from the ventilation system. To

senger compartment, turn the knob to
the right position for warm air or left posi-
tion for cooler air.

Recirculated air position The indicator light on the
button is illuminated whenthe recirculated air positionis selected.
With the recirculated air position selected, air from
passenger compartment
will be drawn through theheating system and heatedor cooled according to thefunction selected.
Outside (fresh) air position The indicator light on the
button is illuminated whenthe outside (fresh) air posi-tion is selected. With the outside (fresh) air position selected, air enters
the vehicle from outside andis heated or cooled accord-ing to the function selected.✽✽NOTICE
Prolonged operation of the heater in the
recirculated air position (without airconditioning selected) may cause fog-ging of the windshield and side windows
and the air within the passenger com-partment may 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 climate control system operation in the recirculated air
position 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
harm or death due to a drop in the
oxygen level and/or body temper-
ature.
Continued climate control system operation in the recirculated air
position can cause drowsiness or
sleepiness, and loss of vehicle
control. Set the air intake controlto the outside (fresh) air position
as much as possible while driv-ing.

position for fan operation.
The fan speed control knob allows you to
control the fan speed of the air flowing
from the ventilation system. To change
the fan speed, turn the knob to the right
for higher speed or left for lower speed.
Setting the fan speed control knob to the
“0” position turns off the fan. D230105AUN

Operation Tips
To keep dust or unpleasant fumes fromentering the car through the ventilation
system, temporarily set the air intakecontrol 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. D230503AFD
Air conditioning (if equipped)
All HYUNDAI Air Conditioning Systems
are filled with environmentally friendly
R-134a refrigerant which does not dam-
age 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 then set the fan speedcontrol to the highest speed.

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 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 aslight change in engine speed as the
air conditioning compressor cycles.
This is a normal system operation
characteristic.
Use the air conditioning system every month if 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 characteristics. D230300AFD-EA
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 authorised HYUNDAI
dealer.✽✽

Checking the amount of air con-
ditioner refrigerant and compres-sor lubricant
When the amount of refrigerant is low,
the performance of the air conditioning is
reduced. Overfilling also has a bad influ-ence on the air conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by an
authorised HYUNDAI dealer.
✽✽NOTICE
It is important when servicing the air
conditioning system that the correct
type and amount of oil and refrigerant isused. Otherwise, damage to the com-
pressor and abnormal system operation
may occur.
WARNING
The air conditioning system should
be serviced by an authorised
HYUNDAI dealer. Improper service
may cause serious injury to the
person performing the service.

Automatic heating and air condi- tioning The automatic climate control system is
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 indicatedby AUTO on the display. The modes,
fan speeds, air intake and air-condi-tioning will be controlled automatically
by temperature setting. 2. Push the temperature control button to
set the desired temperature.
If the temperature is set to the lowestsetting (Lo), the air conditioning sys-
tem 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 airconditioning system can automatically
turn on to decrease the humidity inside
the vehicle, even if the temperature is set
to warm.✽✽ NOTICE
Never place anything over the sensor located on the instrument panel to
ensure better control of the heating andcooling system.
