Recirculated air position
With the recirculated air
position selected, air from the
passenger compartment will
be drawn through the heating
system and heated or cooled
according to the function

„„Type AWith the outside (fresh) air
position selected, air enters
the vehicle from outside
and is heated or cooled
according to the function
selected.
„„Type B
Information
Using the system in the fresh air position is
recommended.
Prolonged operation of the heater in the
recirculated air position (without air
conditioning selected) can cause fogging of
the windshield 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 excessively
dry air in the passenger compartment.
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 system on. It
may cause serious harm or death due
to a drop in the oxygen level and/or
body temperature.
• Continued climate control system
operation in the recirculated 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 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 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 the fresh air position and fan speed
to the desired position, turn on the air
conditioning system, and adjust the
temperature control to the desired
temperature.

Air conditioning
HYUNDAI Air Conditioning Systems are
filled with R-1234yf refrigerant.
1. Start the engine. Push the air
conditioning 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
temperature control to maintain
maximum comfort.
Information
Your vehicle is filled with R1234yf
according to the regulation in your
country at the time of production. You can
find out which air conditioning refrigerant
is applied to your vehicle on the label
located inside of the hood. Refer to chapter
8 for the location of the air conditioning
refrigerant label.
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.
NOTICE
• 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 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 the
recirculated air to the fresh outside air
position.
• 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.
• Use the air conditioning system every
month for a few minutes to ensure
maximum system performance.
• 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
Cabin air filter
OIK047401L[A] : Outside air, [B] : Recirculated air
[C] : Cabin air filter, [D] : Blower
[E] : Evaporator core, [F] : Heater core
The cabin air 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 cabin 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.

Convenient features
5-102
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 reduces the
performance of 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-1234yf
Since the refrigerant is mildly flammable and
operated at high pressure,
the air conditioning system
should only be serviced
by trained and certified
technicians. It is important
that the correct type and
amount of oil and refrigerant
are used.
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.
