Operation Tips
To keep dust or unpleasant fumes
from entering the vehicle through
the ventilation system, temporarily
set the air intake control to the
recirculated air position. Be sure to
return the control to the fresh air
position when the irritation has
passed to keep fresh air in the
vehicle. This will help keep the driv-
er alert and comfortable.
Air for the heating/cooling system
is drawn in through the grilles just
ahead of the windshield. Care
should be taken that these are not
blocked by leaves, snow, ice or
other obstructions.
To prevent interior fog on the wind-
shield, set the air intake control to
the fresh air position and fan speed
to the desired position, turn on the
air conditioning system, and adjust
the temperature control to desired
temperature.Air conditioning
All Kia Air Conditioning Systems are
filled with R-1234yf refrigerant.
1.Start the engine. Press the air con-
ditioning button.
2.Set the mode to the position.
3.Set the air intake control to the out-
side air or recirculated air position.
4.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, set the mode
control to the MAX A/C position,
then set the fan speed control to
the highest speed.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.
CAUTION
When opening the windows in
humid weather, air conditioning
may create water droplets
inside the vehicle. Since exces-
sive water droplets may cause
damage to electrical equipment,
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.
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; howev-
er, continual operation in this mode
may cause the air inside the vehi-
cle 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 ventilation
The system automatically selects the
outside (fresh) air position when the
climate control system operates over
a certain period of time (5 minutes)
in low temperature with the recircu-
lated air position selected. (when
floor mode or bi-level mode)To cancel or reset the Automatic
Ventilation
When the air conditioning system is
on, select Face Level ( ) mode
and while pressing the A/C button,
press the air intake control button 5
times within 3 seconds.
When the automatic ventilation func-
tion is canceled, the indicator light
blinks 3 times at an interval of 0.5
seconds.
The air intake will be automatically
controlled to the fresh air position,
and the flow and air conditioning will
be automatically controlled.
When the automatic ventilation func-
tion is selected, the indicator light
blinks 6 times at an interval of 0.25
seconds.
The air intake will be automatically
controlled to the fresh air position,
and the flow and air conditioning will
be automatically controlled.
After the battery has been dis-
charged or separated, the automatic
ventilation function will be reset, so
please selected, according to you
preference.

Features of your vehicle
Sunroof inside air recircula-
tion (if equipped)
The outside (fresh) air position is
automatically selected when the sun-
roof 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.
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.
