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.

Temperature control
Turn the knob to the right to increase
the temperature. Turn the knob to the
left to decrease temperature.
The temperature will increase or
decrease by 1°F/0.5°C for each but-
ton press. When set to the lowest
temperature setting, the air condi-
tioning will operate continuously.
Temperature unit conversion
If the battery has been discharged or
disconnected, the temperature mode
display will reset to Fahrenheit.
This is a normal condition. You can
switch the temperature mode between
Centigrade to Fahrenheit as follows;
- Automatic climate control systemWhile pressing the OFF button,
press the driver's side AUTO button
for 3 seconds or more. The display
will change from Centigrade to
Fahrenheit, or from Fahrenheit to
Centigrade.

Air intake control
This button is used to select the out-
side (fresh) air position or recirculat-
ed air position.
Recirculated air position
With the recirculated airposition selected, air from
the passenger compart-
ment will be drawn
through the heating sys-
tem and heated or cooled
according to the function
selected.
Outside (fresh) air position
With the outside (fresh) air position selected, air
enters the vehicle from
outside and is heated or
cooled according to the
function selected.
Information
Prolonged operation of the heater in
the recirculated air position (without
air conditioning selected) may cause
fogging of the windshield and side
windows and the air within the pas-
senger compartment may become
stale.
In addition, prolonged use of the air
conditioning with the recirculated air
position selected will result in exces-
sively dry air in the passenger com-
partment.

Continued use of the climate control system operation in
the recirculated air position
can cause drowsiness or
sleepiness, that may cause
loss of vehicle control result-
ing in an accident. Set the air
intake control to the outside
(fresh) air position as much as
possible while driving.
Continued use of the climate control system operation in
the recirculated air position
(without the air conditioning
selected) may allow humidity
to increase inside the vehicle
which may fog the glass and
obscure visibility.
Do not sleep in a vehicle with the air conditioning or heating
system on. It may cause seri-
ous injury or death due to a
drop in the oxygen level
and/or body temperature.
WARNING

Pressing the OFF button turns off the
fan.
Operating the fan speed when the
Engine Start/Stop button is in the
ON position could cause the bat-
tery to discharge. Operate the fan
speed when the engine is running.
Turn the knob to the right ( ) to
increase the fan speed and airflow.
Turn the knob to the left ( ) to
decrease fan speed and airflow.
To adjust the rear fan speed control

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.

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.

Checking the amount of air conditioner refrigerant andcompressor lubricant
When the amount of refrigerant is
low, the performance of the air condi-
tioning is reduced. Overfilling also
has a negative influence on the air
conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by
an authorized retailer of Genesis
Branded products.
It is important that the correct
type and amount of oil and refrig-
erant is used. Otherwise, damage
to the compressor and abnormal
system operation may occur.
The air conditioning system should
be serviced by an authorized retailer
of Genesis Branded products.
Air Conditioning refrigerant label
The actual Air Conditioning refrigerant
label in the vehicle may differ from the
illustration.
Each symbols and specification on
air conditioning refrigerant label
means as below :
1. Classification of refrigerant
2. Amount of refrigerant
3. Classification of Compressor lubri-
cant
Refer to chapter 8 for more detail
location of the air conditioning
refrigerant label.

ant is at very high
pressure, the air con-
ditioning system
should only be serv-
iced by trained and certified
technicians. It is important that
the correct type and amount of
oil and refrigerant is used, oth-
erwise damage to the vehicle
and personal injury may occur.
