Air conditioning
Your Genesis Branded 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.

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 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,
have the system inspected by 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, have the system 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
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.

You can find out which air conditioning
refrigerant is applied to your vehicle on

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 to the
position and fan
speed control 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
If the engine temperature is still cold
after starting, then a brief engine warm
up period may be required for the
vented air flow to become warm or hot.
To Defog Inside Windshield

Auto Defogging System
OJK050074OJK050074
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) Mode will change to defrost to
direct airflow to the windshield.
Step 4) Fan speed will be set to MAX.
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.
