Air intake control
The air intake control button is used
to select either Fresh mode (outside
air) or Recirculation mode (cabin air).
Recirculation mode
When Recirculation mode
is selected, air from the
passenger compartment
will be recirculated through
the system and heated or
cooled according to the
function selected.
Fresh mode
When Fresh mode is
selected, air enters the
vehicle from outside and
is heated or cooled
according to the function
selected.
Information
Operating the system primarily in
Fresh mode is recommended. Use
Recirculation mode temporarily only
when needed.
Prolonged operation of the heater in
Recirculation mode and without the
A/C ON can cause fogging of the
windshield.
In addition, prolonged use of the A/C
ON in Recirculation mode may result
in excessively dry, dehumidified air in
the cabin and may promote formation
of musty vent odor due to stagnant air.
i
OHI048340
• Continued use of the climate
control system operation in
Recirculation mode for a pro-
longed period of time may
cause drowsiness to the
occupants in the cabin. This
may lead to loss of vehicle
control which may lead to an
accident.
• Continued use of the climate
control system operation in
Recirculation mode with the
A/C OFF may allow humidity
to increase inside the cabin.
This may cause condensation
to accumulate on the wind-
shield and obscure visibility.
• Do not sleep in your vehicle or
remain parked in your vehicle
with the windows up and
either the heater or the air
conditioning ON for pro-
longed periods of time. Doing
so may increase the levels of
carbon dioxide in the cabin
which may lead to serious
injury or death.

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.
