Air flow is directed toward the upper
body and face. Additionally, each outlet
can be controlled to direct the air
discharged from the outlet.
Bi-Level (B, C, D, E)
Air flow is directed towards the face and
the floor.
Floor-Level (A, C, D)
Most of the air flow is directed to the
floor, with a small amount of the air
being directed to the windshield, side
window defrosters and side vents.

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.

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.

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.
