Instrument panel vents
The outlet vents 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.Temperature control
The temperature will increase to the max-
imum by turning the knob to the right
extremely.
The temperature will decrease to the
minimum by turning the knob to the left
extremely.
The temperature will increase or
decrease by 1°F/0.5°C.
Temperature setting, the air conditioning
will operate continuously.Adjusting the driver and passenger side
temperature individually
1. Press the DUAL button to operate the
driver and passenger side temperature
individually. Also, if the passenger side
temperature control knob is operated,
it will automatically change to the
DUAL mode as well.

✽NOTICE
Prolonged operation of the heater in the
recirculated air position (without air
conditioning 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 con-
ditioning with the recirculated air posi-
tion selected will result in excessively dry
air in the passenger compartment.
Fan speed control
The fan speed control button allows you
to control the fan speed of the airflow in
the vehicle.
To change the fan speed:
Press the up ( ) button to increase
fan speed.
Press the down ( ) button to decrease fan speed.
To turn off the fan speed, press the OFF
button.
WARNING
Continued use of the climate con- trol system operation in the recir-
culated 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 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.

mate control system. However, you can
still operate the air intake buttons as long
as the engine start/stop button is in the
ON position.
Economy air conditioning button
1. If you push the ECON button while the
air conditioning system is working, the
air conditioning system will work less
and it could improve the fuel efficiency.
2. If you want maximum air conditioning while ECON system is working, turn

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 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 out-
side smell or dust has passed, to keep
fresh air in the vehicle.
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
HYUNDAI Air Conditioning Systems are
filled with environmentally friendly
R-134a refrigerant.
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 recirculated 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 the air conditioning
operates may create water droplets
inside the vehicle. Since excessive
water droplets may cause damage to
electrical 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 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 the air conditioner excessively, the difference between the
temperature 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.

Features of your vehicle
Climate control air filter
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
dealer.
✽ ✽NOTICE
• Replace the filter according to the
Maintenance Schedule.
If the vehicle is being driven in severe
conditions such as dusty, rough roads,
more frequent climate control air fil-
ter inspections and changes are
required.
• When the air flow rate suddenly decreases, the system should be
checked at an authorized 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 negative
influence on the air conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by an
authorized HYUNDAI dealer.
✽ ✽ NOTICE
It is important that the correct type and
amount of oil and refrigerant is used.
Otherwise, damage to the compressor and
abnormal system operation may occur.
WARNING
The air conditioning system for the
Hybrid vehicle should be serviced
by an authorized HYUNDAI dealer.
The Hybrid air conditioning system
is connected to the high voltage
system and requires special fluids,
tools and service procedures.
Improperly servicing the Hybrid air
conditioning system could result in
electrical shock, serious injury, or
even death.
