2018 GENESIS G90 air filter

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.

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.
