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.

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

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, select the Front
Defrost
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 to
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 Genesis Branded Vehicle vehicle
air conditioning system is 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.

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
Cabin air filter
OHI048581L
[A] : Outside air, [B] : Recirculated air
[C] : Climate control 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 retailer of
Genesis Branded products 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,
we recommend that the system be
inspected at an authorized retailer of
Genesis Branded products.

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 retailer of
Genesis Branded products.
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-1234yfSince 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. Air Conditioning refrigerant label

You can find out which air conditioning
refrigerant is applied to your vehicle on
the label located inside of the hood.

WINDSHIELD DEFROSTING AND DEFOGGING
WARNING
Windshield heating
Do not use the
position during cooling operation in extremely humid
weather. 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 could cause
an accident resulting in serious injury
or death. In this case, set the mode
selection button to the
position and fan speed control knob to a lower
speed.
• For maximum defrost performance,
set the temperature control to the
highest temperature setting and
the fan speed control to the highest
setting.
• If warm air to the floor is desired while
defrosting or defogging, set the mode
to the floor-defrost position.
• Before driving, clear all snow and ice
from the windshield, rear window,
side view mirrors, and all side
windows.
• Clear all snow and ice from the
hood and air inlet in the cowl grill
to improve heater and defroster
efficiency and to reduce the
probability of fogging up the inside of
the windshield.
NOTICE

after starting, then a brief engine warm
up period may be required for the
vented air flow to become warm or hot.

Auto Defogging System
ORG3050065
Auto defogging helps reduce the
possibility of fogging up the inside of the
windshield by automatically sensing the
moisture on inside the windshield.
The auto defogging system operates
when the heater or air conditioning is on.
Information
The auto defogging system may not
operate normally, when the outside
temperature is below 14 °F (-10 °C).
When the Auto Defogging System operates, the indicator
will illuminate.
If a high amount of humidity is detected
in the vehicle, the Auto Defogging
System will be enabled. The following
steps will be performed automatically:
Step 1) Air conditioning will turn ON.
Step 2) Air intake control will change to
Fresh mode.
Step 3) Fan speed will be set to MAX.
Step 4) Mode will change to defrost to
direct airflow to the windshield.
If the air conditioning is off or
recirculation mode is manually selected
while Auto Defogging System is ON, the
Auto Defogging System indicator will
blink 3 times to signal that the manual
operation has been canceled.
