Rear outlet vents (F)
The rear outlet vents are controlled by the rear climate control system.
However, external conditions and manual settings also have influences on the
actual operation of the rear outlet vents by blocking air flows or changing air
flow volumes.
The rear outlet vents may blow slightly cooler air when the heater is operat-
ing due to some heat loss through the air ducts from the front of the vehicle.
To prevent this, the rear outlet vents may not blow any air immediately after a
cold start when the outside temperature is detected to be extremely low in
winter and the engine has not sufficiently warmed up.
Side outlet vents (D)
G90 is equipped with temperature sensors inside the side outlet vents to
accurately measure and control air temperature both in the driver’s seat and
the front passenger’s seat. However, when the side outlet vents are closed,
the temperature sensor will measure air temperature only inside the side out-
let vents. For accurate temperature control, open the side outlet vents.

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 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
