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.

Front mode selection button
The mode selection button controls
the direction of the air flow through
the ventilation system.
The air flow outlet port is converted
as follows:
Information
The passenger's side cannot select the
Floor & Defrost ( ) mode.Face-Level (B, C, D, F, G)
Air flow is directed toward the upper
body and face. Additionally, each
outlet can be controlled to direct the
air discharged from the outlet.
A small amount of air blows from the
floor air vents to help provide pleas-
ant air quality inside the passenger
compartment.
Bi-Level (B, C, D, E, F, G)
Air flow is directed towards the face
and the floor.
Floor-Level (A, C, E, D)
Most of the air flow is directed to the
floor, with a small amount of the air
being directed to the windshield and
side window defrosters. Floor & Defrost (A, C, E, D)
Most of the air flow is directed to the
floor and the windshield with a small
amount directed to the side window
defrosters.

the Front Defrost mode.
Operation Tips
To keep dust or unpleasant fumes from entering the car through the
ventilation system, temporarily set
the air intake control to the recircu-
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 conditioning
All Genesis Brand Air Conditioning
Systems are filled with environmen-
tally friendly R-134a refrigerant.
1. Start the engine.
2. Push the air conditioning button.
3. Set the mode to the Face Level mode.
4. Set the air intake control to the recirculated air position. However,
prolonged operation of the recircu-
lated air position will excessively
dry the air. In this case, change the
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.
