Recirculation mode
The indicator light on the
button illuminates when
the recirculated air
position is selected.
With the recirculated air
position selected, air from
the passenger
compartment will be
drawn through the climate
control system and heated
or cooled according to the
function selected.
Fresh mode
The indicator light on the
button will turn off when
the outside (fresh) air
position is selected.
With the outside (fresh) air
position selected, air
enters the vehicle from
outside and is heated or
cooled according to the
function selected.
i Information
Prolonged use of the air conditioning
with the recirculated air position selected
will result in excessively dry air in the
passenger compartment.
WARNING
• Continued use of the climate control
system operation in the recirculated
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
control system operation in the
recirculated 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 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.

System operation
Ventilation
1. Select the Face Level mode.
2. Set the air intake control to fresh
mode.
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 fresh
mode.
3. Set the temperature control to the
desired position.
4. Set the fan speed control to the
desired speed.
5. If desired, turn the air conditioning ON
with the temperature control knob set
to heat in order to dehumidify the air
before it enters into the cabin.
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 vehicle through the
ventilation system, temporarily set the
air intake control to the recirculation
mode. Be sure to return the control
to fresh mode position when the
irritation has passed to keep fresh air
in the vehicle. This will help keep the
driver alert and comfortable.
• To prevent interior fog on the
windshield, set the air intake control
to fresh mode and fan speed to
the desired position, turn on the
air conditioning system, and adjust
the temperature control to desired
temperature.

Air conditioning
HYUNDAI Air Conditioning Systems are
filled with R-134a refrigerant.
1. Start the engine.
2. Push the air conditioning button.
3. Select the Face Level
mode.
4. Set the air intake control to
Recirculation mode temporarily to
allow the cabin to cool quickly. When
the desired temperature in the cabin
is reached, change the air intake
control back to Fresh mode.
5. Adjust the fan speed control and
temperature control to maintain
maximum comfort.
NOTICE
• The refrigerant system should only
be serviced by trained and certified
technicians to insure proper and safe
operation.
• The refrigerant system should be
serviced in a well-ventilated place.
• The air conditioning evaporator
(cooling coil) shall never be repaired
or replaced with one removed from
a used or salvaged vehicle and new
replacement MAC evaporators shall
be certified (and labeled) as meeting
SAE Standard J2842.
i Information
• When using the air conditioning system,
monitor the temperature gauge closely
while driving up hills or in heavy traffic
when outside temperatures are high.
Air conditioning system operation may
cause engine overheating. Continue
to use the blower fan but turn the
air conditioning system off if the
temperature gauge indicates 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 used with
the windows closed.

Convenient features
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
recirculation mode to fresh mode.
• To help reduce moisture inside of
the windows on rainy or humid
days, decrease the humidity inside
the vehicle by operating the air
conditioning system with the windows
and sunroof closed.
• During air conditioning system
operation, 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 only for a few minutes
to ensure maximum system
performance.
• When using the air conditioning
system, you may notice clear water
dripping (or even puddling) on the
ground under the passenger side of
the vehicle. This is a normal system
operation 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 button to
the
position and set the fan speed
control knob to the lowest speed
setting.
System maintenance
Climate control air filter
OIK047401LOIK047401L
[A] : Outside air, [B] : Recirculated air
[C] : Climate control air filter, [D] : Blower
[E] : Evaporator core, [F] : Heater core
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.
We recommend that the climate control
air filter be replaced by an authorized
HYUNDAI dealer according to the
maintenance schedule. If the vehicle is
being driven in severe conditions such
as dusty or rough roads, more frequent
climate control filter inspections and
changes are required.
If the air flow rate suddenly decreases,
we recommend the system be checked
at an authorized HYUNDAI dealer.
i Information
• Replace the filter according to the
Maintenance Schedule.
• If the car is being driven in severe
conditions such as dusty, rough roads,
more frequent climate control air filter
inspections and changes are required.
• When the air flow rate suddenly
decreases, we recommend that the
system be checked by an authorized
HYUNDAI dealer.

Checking the amount of air
conditioner refrigerant and
compressor lubricant
When the amount of refrigerant is low,
the performance of the air conditioning
is reduced. Overfilling also has a bad
influence on the air conditioning system.
Therefore, if abnormal operation is
found, we recommend that the system
be 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. To prevent damage, the air
conditioning system in your vehicle
should only be serviced by trained and
certified technicians.
WARNING
Vehicles equipped with R-134a
Since the refrigerant is
operated at very high
pressure, the air
conditioning system should
only be serviced by trained
and certified technicians.
All refrigerants should be reclaimed
with proper equipment.
Venting refrigerants directly to the
atmosphere is harmful to individuals
and environment. Failure to heed these
warnings can lead to serious injuries.
