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 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

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 Dealer of
Genesis Brand Products according
to the maintenance schedule. If the
car is being driven in severe condi-
tions 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 Dealer of Genesis
Brand Products.

For maximum defrosting, set the temperature control to the extreme
right/hot position and the fan speed
control to the highest speed.
If warm air to the floor is desired while defrosting or defogging, set the
mode to the floor-defrost position.
Before driving, clear all snow and ice from the windshield, rear win-
dow, side view mirrors, and all side
windows.
Clear all snow and ice from the hood and air inlet in the cowl grill to
improve heater and defroster effi-
ciency and to reduce the probability
of fogging up the inside of the wind-
shield.
If the engine temperature is still
cold after starting, then a brief
engine warm up period may be
required for the vented air flow to
become warm or hot.
To defog inside windshield
1. Set the fan speed to the desired position.
2. Select desired temperature.
3. Press the defroster button ( ).
4. The air conditioning will turn on according to the detected ambient
temperature and outside (fresh)
air position will be selected auto-
matically.
If the air conditioning and outside
(fresh) air position are not selected
automatically, adjust the correspon-
ding button manually. If the posi-
tion is selected, lower fan speed is
adjusted to a higher fan speed.
NOTICE
Windshield heating
Do not use the or posi-
tion during cooling operation in
extremely humid weather. The
difference between the temper-
ature of the outside air and that
of the windshield could cause
the outer surface of the wind-
shield to fog up, causing loss of
visibility could cause an acci-
dent resulting in serious injury
or death. In this case, set the
mode selection knob or button
to the position and fan
speed control knob or button to
a lower speed.

the reservoir up to the halfway
mark.
7. Proceed with caution, keeping alert for further signs of overheat-
ing. If overheating happens again,
call an authorized Dealer of
Genesis Brand Products for assis-
tance.
Serious loss of coolant indicates a

Maintenance
The high-pressure cooling system
has a reservoir filled with year-round
antifreeze coolant. The reservoir is
filled at the factory.
Check the antifreeze protection and
coolant level at least once a year, at
the beginning of the winter season
and before traveling to a colder cli-
mate.
Checking the Engine Coolant
Level
Check the condition and connections
of all cooling system hoses and
heater hoses. Replace any swollen
or deteriorated hoses.
The coolant level should be filled
between the F and the L marks on
the side of the coolant reservoir
when the engine is cool.
If the coolant level is low, add enough
distilled (deionized) water to bring
the level to the F mark, but do not
overfill. If frequent additions are
required, we recommend that you
see an authorized Dealer of Genesis
Brand Products for a cooling system
inspection.
