✽ ✽
NOTICE
Whenopening the windows in humid
weather, air conditioning may create
water droplets inside the vehicle.
Since excessive water droplets may
cause damage to electrical equip-
ment, air conditioning should only be
used with the windows closed.
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.
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.
During air conditioning system
operation, you may occasionally
notice a slight change in engine
speed as the air conditioning com-
pressor cycles. This is a normal
system operation characteristic.
Use the air conditioning system
every month only for a few minutes
to ensure maximum system per-
formance.CAUTION - Excessive A/C
Use
When using the air conditioning
system, monitor the tempera-
ture gauge closely while driving
up hills or in heavy traffic when
outside temperatures are high.
Air conditioning system opera-
tion may cause engine over-
heating. Continue to use the
blower fan but turn the air con-
ditioning system off if the tem-
perature gauge indicates engine
overheating.

When using the air conditioning
system, you may notice clear water
dripping (or even puddling) on the
ground under the passenger side
of the vehicle. This is a normal sys-
tem operation characteristic.
Operating the air conditioning sys-
tem in the recirculated air position
provides maximum cooling, how-
ever, continual operation in this
mode may cause the air inside the
vehicle to become stale.
During cooling operation, you may
occasionally notice a misty air flow
because of rapid cooling and
humid air intake. This is a normal
system operation characteristic.Automatic Air Ventilation
When operating heater and air con-
ditioner for the vehicle ventilation, if
you maintain the Recirculation mode
for 30 minutes or over at low temper-
ature, it automatically changes to
Fresh mode.
Automatic Air Ventilation control
procedure
When set up or release the automat-
ic air ventilation function, select the
Mode Selection button at heater or
air conditioner on. And press the Air
Intake Control button for 5 times or
over within 3seconds together within
3 seconds together within 3 seconds
together with pressing the Air
Conditioning button. When release
the automatic ventilation function,
the Recirculation mode indicator will
blink 3 times at 0.5 second intervals
and air direction, air volume,
Recirculation/Fresh mode, and air
conditioner is automatically con-
trolled.When it set the automatic ventilation
function, the Recirculation mode
indicator will blink 6 times at 0.25
seconds intervals and air direction,
air volume, Recirculation/Fresh
mode, and air conditioner is auto-
matically controlled.
Auto dehumidify is activated when
you select ‘Settings →Vehicle →
Climate →Automatic Ventilation →
Auto dehumidify’ from the Settings
menu in the Infotainment System
screen.

Features of your vehicle
Sunroof inside air recircula-
tion
The outside (fresh) air position is
automatically selected, when the
sunroof is opened.
When you select the recirculated air
position, the system maintains the
recirculated air position for 3 minutes
and then automatically converts to
the outside (fresh) air position.
When the sunroof is closed, the air
intake position will return to the orig-
inal position that was selected.
Activate upon Washer Fluid
Use
To prevent the odor from entering to
inside the vehicle, the ventilation sys-
tem changes to Recirculated Air
Mode for a while when the wind-
shield washer fluid sprayed.
However, at low outside temperature,
to prevent from windshield fogging,
the system continues to outside air
mode.
System setting
1. ENGINE START/STOP button is
On.
2. Select Floor-Level ( ) air flow
direction by pressing
Mode Selection button.
3. With pressing Air Conditioning but-
ton, press the Recirculated Air but-
ton more than 4 times within 2
seconds.

Climate control air filter
The climate control air filter installed
behind the glove box, filters dust or
other pollutants that come into the
vehicle from the outside through the
heating and air conditioning system. If
dust or other pollutants accumulate in
the filter over a period of time, air flow
from the air vents may decrease,
resulting in moisture accumulation on
the inside of the windshield even
when the outside (fresh) air position is
selected. If this happens, have the cli-
mate control air filter replaced by an
authorized Kia dealer.
✽ ✽
NOTICE
• Replace the filter every 15,000
miles or once a year.
If the vehicle is being driven in
severe conditions such as dusty or
rough roads, more frequent air
conditioner filter inspections and
changes are required.
• When the air flow rate suddenly
decreases, the system should be
checked at an authorized Kia
dealer.

is represented below ;
1. Classification of refrigerant
2. Amount of refrigerant
3. Classification of Compressor lubri-
cant
4. Caution
5. Flammable Refrigerant
6. To requires Registered Technician
to Service Air Conditioning system
You can find out which air condition-
ing refrigerant is applied to your vehi-
cle on the label inside of the engine
compartment.
Refer to section 8 for more detail on
the location of air conditioning refrig-
erant label.Checking the amount of air
conditioner refrigerant and
compressor 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 Kia dealer.
WARNING - Vehicles
equipped with R-1234yf
Since the refrigerant
is mildly flammable
and operated at high
pressure, the air con-
ditioning system
should only be serv-
iced by trained and
certified technicians.
(Refer to the SAE
J2845)
It is important that the correct
type and amount of oil and
refrigerant are used.
All refrigerants should be
reclaimed with proper equip-
ment.
Venting refrigerants directly to
the atmosphere is harmful to
individuals and environment.
Failure to heed these warnings
can lead to serious injuries.

The refrigerant label is located on
the underside of the hood.
CAUTION- AC Repair
It is important that the correct
type and amount of oil and
refrigerant is used, otherwise
damage to the vehicle may
occur. To prevent damage, the
air conditioning system in your
vehicle should only be serviced
by trained and certified techni-
cians.

the mode to the floor-defrost posi-
tion.
Before driving, clear all snow and
ice from the windshield, rear win-
dow, outside rear 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 probabili-
ty of fogging up the inside of the
windshield.Automatic climate control
system
To defog inside windshield
1. Set the fan speed to the desired
position.
2. Select desired temperature.
3. Press the defroster button ( ).
4. The outside (fresh) air position will

WINDSHIELD DEFROSTING AND DEFOGGING
WARNING - 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 the
windshield could cause the
outer surface of the windshield
to fog up, causing loss of visi-
bility. In this case, set the mode
selection to the position
and fan speed control to the
lower speed.
