Air intake control
This button is used to select the out-
side (fresh) air position or recirculat-
ed air position.
Recirculated air position
With the recirculated airposition selected, air from
the passenger compart-
ment will be drawn
through the heating sys-
tem and heated or cooled
according to the function
selected.
Outside (fresh) air position
With the outside (fresh) air position selected, air
enters the vehicle from
outside and is heated or
cooled according to the
function selected.
Information
Prolonged operation of the heater in
the recirculated air position (without
air conditioning selected) may cause
fogging of the windshield and side
windows and the air within the pas-
senger compartment may become
stale.
In addition, prolonged use of the air
conditioning with the recirculated air
position selected will result in exces-
sively dry air in the passenger com-
partment.

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

Air quality system (AQS)
The air inflow from outside the vehi-
cle can be automatically controlled.
Press the button to activate the air
quality control system.
When using AQS mode, AQS (Air
Quality System) automatically sens-
es outdoor air pollutants and mini-
mizes them from entering the vehi-
cle, however, unpleasant or foul
odors that might be present may still
be noticeable within the vehicle.
Exhaust gas cutoff mode :
Air enters the vehicle from the outside.
If exhaust gas from the outside of the
vehicle is detected, the exhaust gas cut-
off mode is automatically converted
from the outside air position to the recir-
culated air position to prevent exhaust
gas from entering the vehicle.
Information
• The AQS button indicator will imme-diately illuminate when the engine is
started with the AQS in the ON posi-
tion. However, the AQS starts oper-
ating after 40 seconds.
• The AQS filters out toxic exhaust (i.e. NO, NO2, SO2, CO, CxHy) to pre-
vent it from entering the passenger
compartment but, does not totally
block odor.
The AQS does not operate in any of
the following situations :
The AQS button is re-repressed tothe OFF position.
Either the outside (fresh) air posi- tion or the recirculated air position
is selected.
The defroster button is pressed to the ON position, or the floor &
defrost ( ) mode is selected.
The temperature is set to either the highest (HI) or the lowest (Lo) posi-
tion, while the climate control sys-
tem is automatically controlled
(AUTO button indicator ON).
The OFF button of the climate con- trol system is selected.
The auto defogging system oper- ates to defog the front windshield.
Information
If the windows fog up with the
Recirculation or AQS mode selected,
set the air intake control to the fresh
air position or or turn off the AQS
mode.
Fan speed control
Press the ( ) button to increase the
fan speed and air flow. Press the ( )

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.

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.
