position, the system maintains the
recirculated air position for 3 minutes
and then automatically converts to
the outside (fresh) air position.

intake position will return to the orig-
inal position that was selected.
Recirculated air at washer
fluid spray
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.

Climate control air filter
(if equipped)
The climate control air filter installed
behind the glove box filters the 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, the
air flow from the air vents may
decrease, resulting in moisture accu-
mulation on the inside of the wind-
shield even when the outside (fresh)
air position is selected. If this hap-
pens, have the climate control air fil-
ter replaced by an authorized Kia
dealer.
✽ ✽
NOTICE
• Replace the filter according to the
Maintenance Schedule.
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.

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.

Features of your vehicle
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 impact on the air con-
ditioning 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.

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 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
be selected automatically and the
air conditioning will turn on accord-
ing to the detected ambient tem-
perature.
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. If this occurs, set the
mode selection to the posi-
tion and fan speed control to
the lower speed.

adjusted to a higher fan speed.To defrost outside windshield
1. Set the fan speed to the highest
position.
2. Set the temperature to the
extreme hot (HI) position.
3. Press the defroster button ( ).
4. The outside (fresh) air position will
be selected automatically and the
air conditioning will turn on
according to the detected ambient
temperature.
Defogging logic
To reduce the possibility of fogging
up the inside of the windshield, the
air intake or air conditioning is con-
trolled automatically according to
certain conditions such as or
position. To cancel automatic defog-
ging logic or return to the automatic
defogging logic, do the following.

Automatic climate control system
1. Turn the ignition switch to the ON
position.
2. Press the defroster button ( ).
3. While pressing the air conditioning
button (A/C), press the air intake
control button at least 5 times with-
in 3 seconds.

times with 0.5 second of interval. It
indicates that the defogging logic is
canceled or returned to the pro-
grammed status.
If the battery has been discharged or
disconnected, it resets to the defog
logic status.
Auto defogging system
Auto defogging reduces the probabil-
ity of fogging up the inside of the
windshield by automatically sensing
the moisture of inside the windshield.
The auto defogging system operates
when the heater or air conditioning is
on.This indicator illuminates
when the auto defogging
system senses the mois-
ture on the inside of the
windshield and operates.
If more moisture is in the vehicle,
higher steps operate as follow. For
example if auto defogging does not
defog inside the windshield at step 1
Outside air position, it tries to defog
again at step 2 Operating the air con-
ditioning.
Step 1 : Outside air position
Step 2 : Operating the air condition-
ing
Step 3 : Blowing air flow toward the
windshield
Step 4 : Increasing air flow toward
the windshield
