Automatic Temperature Control
Mode
The Automatic Climate Control System
is controlled by setting the desired
temperature.
1. Press the AUTO button.
The mode selection, fan speed,
air intake and air-conditioning will
be controlled automatically by the
temperature setting you select.
OJX1059246
2. When the climate control system is
being automatically controlled, fan
speed can be selected (Low/Medium/
High).
-HIGH: Use when quick heating or
cooling is preferred with higher fan
speed capability.
-MEDIUM: Use when medium fan
speed is preferred for cooling or
heating with moderate fan speed
capability.
-LOW: Use when low fan speed is
preferred for cooling or heating with
lower fan speed capability.
3. Turn the temperature control knob
to the desired temperature. If the
temperature is set to the lowest
setting (Lo), the air conditioning
system will operate continuously.
After the interior has cooled
sufficiently, adjust the knob to
a higher temperature set point
whenever possible.
To turn the automatic operation off,
select any function of the following:
- Mode selection button
-Front windshield defroster button
(Press the button one more time
to deselect the front windshield
defroster function. The ‘AUTO’
sign will illuminate on the climate
information screen once again.)
-Fan speed control icon or knob
-A/C (air conditioning) icon
The selected function will be controlled
manually while other functions operate
automatically.
For your convenience and to improve the
efficiency of the climate control, use the
AUTO button and set the temperature to
72 °F (22 °C).
To change the temperature unit from °C
to °F or °F to °C:
Press the AUTO button for 3 seconds
while pressing the OFF button.

Never place anything near the ambient
light/solar sensor to ensure better control
of the heating and cooling system.
Manual Temperature Control
Mode
The heating and cooling system can be
controlled manually by pushing buttons
other than the AUTO button. In this case,
the system works sequentially according
to the order of buttons selected.
When pressing any button except the
AUTO button while using automatic
operation, the functions not selected will
be controlled automatically.
1. Start the vehicle.
2. Set the mode to the desired position.
To improve the effectiveness of
heating and cooling, select the mode
according to the following:
-Heating:
-Cooling:
3. Set the temperature control to the
desired position.
4. Set the air intake control to Fresh or
Recirculation mode.
5. Set the fan speed control to the
desired speed.
6. If air conditioning is desired, turn the
air conditioning system on.
7. Press the AUTO button to revert
back to full automatic control of the
system.
The climate control system settings
will be maintained, even when the
vehicle is turned OFF. However, the
climate control system settings will be
initialized when the battery has been
discharged, or when the cables have
been disconnected.
In this case, adjust the climate control
system settings again.
When starting the vehicle in cold
weather the more efficient way to heat
the passenger compartment is to do the
following.
- Turn off or lower the blower, right
after starting the engine.
• Allow the engine to warm up during
this time since the air flow from the
heater is still cold.
-After a few minutes of engine warm
up, turn on or set the fan to a higher
level and adjust the temperature
setting to hot.

System Operation
Cooling / Ventilation
1. Select the Face Level mode.
2. Set the air intake control to fresh or
recirculation mode.
3. Set the temperature control to the
desired position.
4. Set the fan speed control to the
desired speed.
Heating
1. Select the Floor Level mode.

recirculation mode.
3. Set the temperature control to the
desired position.
4. Set the fan speed control to the
desired speed.
5. If desired, turn the air conditioning ON
with the temperature control knob set
to heat in order to dehumidify the air
before it enters into the cabin.
If the windshield fogs up, select the Front
Defrost
mode.
Operation Tips
• To keep dust or unpleasant fumes
from entering the vehicle through the
ventilation system, temporarily set the
air intake control to the recirculation
mode. Return the control to the to
Fresh mode when the unpleasant air
outside has diminished. This will help
keep the driver alert and comfortable.
• To help prevent the inside of the
windshield from fogging, set the air
intake control to fresh mode and the
fan speed to the desired position, turn
on the air conditioning system, and
adjust the temperature control to the
desired temperature.
Air conditioning
Your Genesis Branded Vehicle vehicle
air conditioning system is filled with
R-1234yf refrigerant.
1. Start the vehicle.
2. Press the air conditioning button.
3. Set the mode to the Face Level mode.
4. Set the air intake control to
Recirculation mode temporarily to
allow the cabin to cool quickly. When
the desired temperature in the cabin
is reached, change the air intake
control back to Fresh mode.
5. Adjust the fan speed control and
temperature control to maintain
maximum comfort.
When maximum cooling is desired, set
the temperature control to the lowest
position, then set the fan speed control
to the highest setting.
NOTICE
When using the air conditioning system,
monitor the engine temperature gauge
closely while driving up hills or in heavy
traffic when outside temperatures are
high. Air conditioning system operation
when climbing a steep grade or in
high outside ambient temperatures
can cause engine overheating.
Continue to use the fan, but turn the air
conditioning system off if the engine
temperature gauge indicates engine
overheating.

Air conditioning system operation tips
• If the vehicle has been parked in
direct 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
recirculation mode to fresh mode.
• 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 windows
and sunroof closed.
• Use the air conditioning system
every month only for a few minutes
to ensure maximum system
performance.
• 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 to the
position and fan speed control to the
lowest speed.
System Maintenance
Cabin air filter
OHI048581L
[A] : Outside air, [B] : Recirculated air
[C] : Climate control air filter, [D] : Blower
[E] : Evaporator core, [F] : Heater core
The cabin air filter is installed behind
the glove box. It filters the dust or other
pollutants that enter the vehicle through
the heating and air conditioning system.
We recommend that the cabin air filter
be replaced by an authorized retailer of
Genesis Branded products according to
the maintenance schedule. If the vehicle
is being driven in severe conditions such
as dusty or rough roads, more frequent
cabin air filter inspections and changes
are required.
If the air flow rate suddenly decreases,
we recommend that the system be
inspected at an authorized retailer of
Genesis Branded products.
