Continued use of the climate control system operation in
the recirculated air position
can cause drowsiness or
sleepiness, that may cause
loss of vehicle control result-
ing in an accident. Set the air
intake control to the outside
(fresh) air position as much as
possible while driving.
Continued use of the climate control system operation in
the recirculated air position
(without the air conditioning
selected) 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 seri-
ous injury or death due to a
drop in the oxygen level
and/or body temperature.
WARNING

Pressing the OFF button turns off the
fan.
Operating the fan speed when the
Engine Start/Stop button is in the
ON position could cause the bat-
tery to discharge. Operate the fan
speed when the engine is running.

Operation Tips
To keep dust or unpleasant fumes from entering the car through the
ventilation system, temporarily set
the air intake control to the recircu-
lated air position. Return the con-
trol to the fresh air position when
the irritation has passed. This will
help keep the driver alert and com-
fortable.
To prevent the inside of the wind- shield from fogging, set the air
intake control to the fresh air posi-
tion and fan speed to the desired
position, turn on the air conditioning
system, and adjust the temperature
control to desired temperature.
Air conditioning
All Genesis Branded Vehicle Air
Conditioning Systems are filled with
environmentally friendly R-134a
refrigerant.
1. Start the engine.
2. Push the air conditioning button.
3. Set the mode to 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, change the
air position.
5. Adjust the fan speed control and temperature control to maintain
maximum comfort.
When maximum cooling is desired,
set the temperature control to the
extreme left position then set the fan
speed control 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 indirect 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 win-
dows and sunroof closed.
Use the air conditioning system every month only for a few minutes
to ensure maximum system per-
formance.
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 knob or button to
the position and fan speed
control to the lower speed.
System Maintenance
Climate control air filter
This filter is installed behind the glove
box. It filters the dust or other pollu-
tants that enter the vehicle through the
heating and air conditioning system.
Have the climate control air filter
replaced by an authorized retailer of
Genesis Branded products accord-
ing to the maintenance schedule. If
the car is being driven in severe con-
ditions such as dusty or rough roads,
more frequent air conditioner filter
inspections and changes are
required.
If the air flow rate suddenly decreas-
es, the system should be checked at
an authorized retailer of Genesis
Branded products.

Checking the amount of air conditioner refrigerant andcompressor lubricant
When the amount of refrigerant is
low, the performance of the air condi-
tioning is reduced. Overfilling also
has a negative influence on the air
conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by
an authorized retailer of Genesis
Branded products.
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.
The air conditioning system should
be serviced by an authorized retailer
of Genesis Branded products.
Air Conditioning refrigerant label
The actual Air Conditioning refrigerant
label in the vehicle may differ from the
illustration.
Each symbols and specification on
air conditioning refrigerant label
means as below :
1. Classification of refrigerant
2. Amount of refrigerant
3. Classification of Compressor lubri-
cant
Refer to chapter 8 for more detail
location of the air conditioning
refrigerant label.

Because the refriger-
ant is at very high
pressure, the air con-
ditioning system
should only be serv-
iced by trained and certified
technicians. It is important that
the correct type and amount of
oil and refrigerant is used, oth-
erwise damage to the vehicle
and personal injury may occur.

For maximum defrosting, set the
temperature control to the extreme
right/hot position and the fan speed
control to the highest speed.
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 win-
dow, 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 effi-
ciency and to reduce the probability
of fogging up the inside of the wind-
shield.
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
1. Set the fan speed to the desired position.
2. Select desired temperature.
3. Press the defroster button ( ).
4. The air conditioning will turn on according to the detected ambient
temperature and outside (fresh)
air position will be selected auto-
matically.
If the air conditioning and outside
(fresh) air position are not selected
automatically, adjust the correspon-
ding button manually. If the posi-
tion is selected, lower fan speed is
adjusted to a higher fan speed.
NOTICE
Windshield heating
Do not use the or posi-
tion during cooling operation in
extremely humid weather. The
difference between the temper-
ature of the outside air and that
of the windshield could cause
the outer surface of the wind-
shield to fog up, causing loss of
visibility could cause an acci-
dent resulting in serious injury
or death. In this case, set the
mode selection knob or button
to the position and fan
speed control knob or button to
a lower speed.
