Information
Operating the system primarily in Fresh
mode is recommended. Use Recirculation mode temporarily only when needed.
Prolonged operation of the heater in
Recirculation mode and without the air conditioning ON can cause fogging of the
windshield. In addition, prolonged use of
the air conditioning ON in Recirculation
mode may result in excessively dry,
dehumidified air in the cabin and may
promote formation of musty vent odor due
to stagnant air.
WARNING
• Continued use of the climate control
system operation in Recirculation
mode for a prolonged period of
time may cause drowsiness to the
occupants in the cabin. This may lead
to loss of vehicle control which may
lead to an accident.
• Continued use of the climate control
system operation in Recirculation
mode with the air conditioning OFF
may allow humidity to increase
inside the cabin. This may cause
condensation to accumulate on the
windshield and obscure visibility.
• Do not sleep in your vehicle or
remain parked in your vehicle with
the windows up and either the
heater or the air conditioning ON for
prolonged periods of time. Doing so
may increase the levels of carbon
dioxide in the cabin which may lead
to serious injury or death.
Fan speed control
„„Type A
ONE1051109
„„Type B
ONE1051121
The fan speed can be set to the desired
speed by adjusting the

Information
To help improve microphone voice input sound, fan speed may automatically slow
down for a couple of minutes when you
activate voice recognition or hands free.
NOTICE
Operating the fan when the Start/Stop
button is in the OFF position could cause
the battery to discharge. Operate the fan
when the vehicle is running.

System Operation
Cooling / Ventilation
1. Select the Face Level (
) mode in the
infotainment screen.
2. Set the air intake control to fresh or recirculation mode.
3. Set the temperature to the desired position.
4. Set the fan speed to the desired speed.
Heating

) 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. Return the control to the
Recirculation mode to the Fresh mode
when the unpleasant air outside has
diminished. This will help keep the
driver alert and comfortable.
• To help prevent the inside of the
windshield from fogging, set the air
intake control to fresh mode and the
fan speed to the desired position, turn
on the air conditioning system, and
adjust the temperature control to the
desired temperature. Air conditioning
Your HYUNDAI Vehicle air conditioning
system is filled with R-1234yf refrigerant.
1. Touch the [CLIMATE] icon to display
climate information the infotainment
screen.
2. Select A/C icon (indicator light ON) in the climate information screen to
activate the air-condition.
3. Set the temperature low.
4. Set the direction of air flow by
touching the mode selection icon.
5. Touch the HEAT icon (indicator light OFF) to turn on the air-condition.
When maximum cooling is desired, set
the temperature to the lowest position,
then set the fan speed control to the
highest setting.
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.
• Use the air conditioning system
every month only for a few minutes
to ensure maximum system
performance.
• If you operate 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 to the

position and fan speed control to the
lowest speed.

System Maintenance
Climate control air filter
OHI048581L
[A] : Outside air, [B] : Recirculated air
[C] : Climate control air filter, [D] : Blower
[E] : Evaporator core, [F] : PTC & Inner condenser
The cabin air filter is installed behind the
front trunk. It filters the dust or other
pollutants that enter the vehicle through
the heating and air conditioning system.
Have the cabin air filter 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
cabin air filter inspections and changes
are required.
If the air flow rate suddenly decreases,
have the system inspected 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 conditioning
is reduced. Overfilling also reduces the
performance of the air conditixoning
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. To prevent damage, the air
conditioning system in your vehicle
should only be serviced by trained and
certified technicians.
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.

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.
