Air Quality System (AQS)
This system automatically senses
outdoor air pollutants and minimizes
their flow into the vehicle. However,
unpleasant or foul odors that might
be present may still be noticeable
within the vehicle.
To turn the AQS ON, press the button.
If the windows fog up with the
Recirculation mode or AQS mode
selected, set the air intake control to
Fresh mode or AQS control to OFF.
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 to
the OFF position.
• Either Fresh mode or the
Recirculation mode is selected.
• The front defroster button is
pressed ON 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 LED ON).
• The OFF button of the climate con-
trol system is selected.
• The Auto Defogging system oper-
ates to defog the front windshield.

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
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 recir-
culation 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 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 lowest speed.
System Maintenance
Cabin air filter
[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 condi-
tioning 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 and/or
if transporting pets or occupants
smoke inside the vehicle, then more
frequent cabin air 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.

ance, set the temperature control
knob to the highest temperature
setting (rotated all the way to the
right) and the fan speed control to
the highest setting.

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 ( ).

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
