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.

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.

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 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 Dealer of
Genesis Brand Products according
to the maintenance schedule. If the
car is being driven in severe condi-
tions 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 Dealer of Genesis
Brand 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 Dealer of Genesis
Brand 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 Dealer
of Genesis Brand 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.
