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.
Fan speed control
ONX4050107NONX4050107NTurn the knob to the right to increase
the fan speed and airflow. Turn the knob
to the left to decrease fan speed and
airflow.
Setting the fan speed control knob to the
“0” position turns off the fan.
NOTICE
Operating the fan speed when the
ignition switch is in the ON position
could cause the battery to discharge.
Operate the fan speed when the engine
is running.

System Operation
Ventilation
1. Set the mode to the position.
2. Set the air intake control to the
outside (fresh) air position.
3. Set the temperature control to the
desired position.
4. Set the fan speed control to the
desired speed.
Heating
1. Set the mode to the position.
2. Set the air intake control to the
outside (fresh) air position.
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, set the mode
to the
or position.
Operation Tips
• To help 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 vehicle.
2. Press the air conditioning button.
3. Set the mode to 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.
When maximum cooling is desired, set
the temperature control to the lowest
position, then set the fan speed control
to the highest setting.
NOTICE
• When using the air conditioning
system, monitor the engine
temperature gauge closely while
driving up hills or in heavy traffic
when outside temperatures are high.
Air conditioning system operation
when climbing a steep grade or in
high outside ambient temperatures
can cause engine overheating.
Continue to use the fan, but turn
the air conditioning system off if the
engine temperature gauge indicates
engine overheating.
• 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.

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 knob to
the
position and set the fan speed
control knob to the lowest speed
setting.
System Maintenance
Cabin air filter
OIK047401LOIK047401L[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.
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 climate control filter
inspections and changes are required.
If the air flow rate suddenly decreases,
the system should be checked at an
authorized HYUNDAI dealer.

Air Conditioning Performance and
Maintenance at Your HYUNDAI
Dealer
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,
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.
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.
