Air conditioning
Kia Air Conditioning Systems are
filled with R-1234yf refrigerant.
1. Start the engine. Push the air con-
ditioning button.
2. Set the mode to the position.
3. Set the air intake control to the recirculated air position. However,
prolonged operation in the recircu-
lated air position will excessively
dry the air. In this case, change the
air position.
4. Adjust the fan speed control and temperature control to maintain
maximum comfort.
The refrigerant system should only be serviced by trained and certified
technicians to ensure proper and
safe operation.
The refrigerant system should be serviced in a well-ventilated place.
The air conditioning evaporator (cooling coil) shall never be
repaired or replaced with one
removed from a used or salvaged
vehicle and new replacement MAC
evaporators should be certified
(and labeled) as meeting SAE
Standard J2842.
✽ ✽ NOTICE
When opening 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 for a few minutes to
ensure maximum system perform-
ance.
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
operating characteristic of the sys-
tem.CAUTION - Excessive A/C
While using the air conditioningsystem, monitor the tempera-ture gauge closely while drivingup hills or in heavy traffic whenoutside temperatures are high.Air conditioning system opera-tion may cause engine over-heating and potential enginedamage. Continue to use theblower fan but turn the air con-ditioning system off if the tem-perature gauge indicates engineoverheating.

Features of your vehicle
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
operating characteristic of the sys-
tem.Climate control air filter
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 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 according to the
Maintenance Schedule.
If the vehicle is being driven in
severe conditions such as dusty,
rough roads, more frequent cli-
mate control air filter inspections
and changes are required.
• When the air flow rate suddenly decreases, the system be checked
at an authorized Kia dealer.

Recirculated air position
With the recirculated airposition selected, air
from the passenger
compartment will be
drawn through the heat-
ing system and heated
or cooled according to
the function selected.
Outside (fresh) air position If the recirculated airposition is not selected
or turned off, air enters
the vehicle from outside
and is heated or cooled
according to the function
selected. Prolonged operation of the heater in
the recirculated air position (without air
conditioning selected) may cause fog-
ging of the windshield and side win-
dows, and the air within the passenger
compartment may become stale.
In addition, prolonged operation of
the air conditioning with the recircu-
lated air position selected will result
in excessively dry air in the passen-
ger compartment.
WARNING- Reduced
Visibility
Continuous use of the climate
control system in the recirculat-
ed air position may allow
humidity to increase inside the
vehicle which may fog the glass
and obscure visibility.
WARNING- Sleeping with A/C on
Do not sleep in a vehicle with
the air conditioning or heating
system on as this may cause
serious harm or death due to a
drop in the oxygen level and/or
body temperature.
WARNING- Recirculated air
Continued use of the climate
control system in the recirculat-
ed air position can cause
drowsiness or sleepiness, and
loss of vehicle control. Set the
air intake control to the outside
(fresh) air position as much as
possible while driving.

return the control to the fresh air
position when the dust or fumes
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.

Checking the amount of air
conditioner refrigerant and
compressor lubricant
When the amount of refrigerant is
low, the performance of the air con-
ditioning 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.
