Air conditioning
Your HYUNDAI vehicle air condition-
ing system is filled with R-1234yf
refrigerant.
1. Start the engine.
2. Press the air conditioning button.
3. Select the Face Level mode.
4. Set the air intake control to the
recirculated air position. However,
prolonged operation of the recircu-
lated air position will excessively
dry the air. In this case, switch the
air intake control to the outside
(fresh) air position. The indicator
light on the button will turn OFF.
5. Adjust the fan speed control and
temperature control to maintain
maximum comfort.
When maximum cooling is desired,
rotate the temperature control knob
to the left-most position (MAX AC).
Then set the fan speed control knob
to the highest speed.When using the air conditioning
system, monitor the engine tem-
perature gauge closely while driv-
ing up hills or in heavy traffic
when outside temperatures are
high. Air conditioning system
operation can cause engine over-
heating. Continue to use the blow-
er fan, but turn the air condition-
ing system off if the engine tem-
perature gauge indicates engine
overheating.
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 recir-
culated 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 condi-
tioning system with the windows and
sunroof closed.
Use the air conditioning system
every month for a few minutes to
ensure maximum system perform-
ance.
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 wind-
shield to fog up, causing loss of visi-
bility. 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
[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 condi-
tioning system.Have the climate control air filter
replaced by an authorized HYUNDAI
dealer according to the maintenance
schedule. If the car 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 decreas-
es, the system should be checked at
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 con-
ditioning is reduced. Overfilling also
reduces the performance of the air
conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by
an authorized HYUNDAI dealer.
It is important that the correct
type and amount of oil and refrig-
erant is used. Otherwise, damage
to the compressor and abnormal
system operation may occur. To
prevent damage, the air condition-
ing system in your vehicle should
only be serviced by trained and
certified technicians.

Air Conditioning refrigerant label
You can find out which air condition-
ing refrigerant is applied to your vehi-
cle on the label located on the under-
side of the hood.Each symbols and specification on
the air conditioning refrigerant label
is represented as below:
1. Classification of refrigerant
2. Amount of refrigerant
3. Classification of compressor lubri-
cant
4. Caution
5. Flammable refrigerant
6. To require registered technician to
service air conditioning system Vehicles equipped with R-1234yf
Since the refrigerant is
mildly flammable and
operated at high pres-
sure, the air condition-
ing system should only
be serviced by trained
and certified techni-
cians. 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 individu-
als and environment. Failure to
heed these warnings can lead to
serious injuries.

A solar compensation sensor is
located inside the vehicle on the
center of the dash near the front
windshield. In order to ensure
optimum control of the heating
and cooling system, never block
the sensor or place anything near
the sensor while the climate con-
trol system is operating.
Manual Heating and Air
Conditioning
The heating and cooling system can
be controlled manually by pushing
buttons other than the AUTO button.
In this case, the system works

mode according to the following:
- Heating:
- Cooling:3. Set the temperature control to the
desired position.
4. Set the air intake control to the
outside (fresh) air position.
5. Set the fan speed control to the
desired speed.
6. If air conditioning is desired, turn
the air conditioning system on.
7. Press the AUTO button to convert
to full automatic control of the sys-
tem.
When starting the vehicle in cold
weather using manual temperature
control, operate the system in the fol-
lowing method to improve heating.
- Turn off or lower the blower, right
after starting the engine.
- Allow the engine to warm up during
this time since the air flow from the
heater is still cold.
