Features of your vehicle
Prolonged operation of the heater in
the recirculated air position (without
air conditioning selected) may cause
fogging of the windshield and side
windows and the air within the pas-
senger compartment may become
stale.
In addition, prolonged use of the air
conditioning with the recirculated air
position selected will result in exces-
sively dry air in the passenger com-
partment.
Sunroof inside air recirculation(if equipped)
If the sunroof opens while the heater
or Air Conditioning system operates,
the outside (fresh) air will be select-
ed automatically for ventilating the
car. Then, if you select the recirculat-
ed air position, the outside (fresh) air
will be selected automatically after 3
minutes.
If you close the sunroof, the intake
mode will be changed to the previous
selected mode.
Fan speed control

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 - 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.
WARNING - Sleeping with
A/C on
Do not sleep in a vehicle with
the air conditioning or heating
on as this may cause serious
harm or death due to a drop in
the oxygen level and/or body
temperature.

1.Set the mode to the position.
2.Set the air intake control to the out-side (fresh) air position.
3.Set the temperature control to the desired position.
4.Set the fan speed control to the desired speed.
Heating
1.Set the mode to the position.
2.Set the air intake control to the out-side (fresh) air position.
3.Set the temperature control to the desired position.
4.Set the fan speed control to the desired speed.
5.If dehumidified heating is desired, turn the air conditioning system (if
equipped) on.
If the windshield fogs up, set the mode to the
orposition. 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 (if equipped)
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.

✽ ✽
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 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, 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.CAUTION - Excessive A/C
Use
When 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. Continue to use theblower fan but turn the air con-ditioning system off if the tem-perature gauge indicates engineoverheating.

Features of your vehicle
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 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.
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
Because the refriger-
ant is mildly inflam-
mable and at very
high pressure, the air
conditioning system
should only be serv-
iced by trained and
certified technicians.
It is important that the correct
type and amount of oil and
refrigerant is used.
Otherwise, it may cause dam-
age to the vehicle and personal
injury.

WARNING
The oil and refrigerant in your
vehicle's air conditioning sys-
tem is under very high pres-
sure. If proper service proce-
dures are not followed an explo-
sion may result. To reduce the
risk of serious injury or death,
the air conditioning system in
your vehicle should only be
serviced by trained and certi-
fied technicians.
CAUTION
It is important that the correct
type and amount of oil and refrig-erant is used, otherwise damageto the vehicle may occur. To pre-vent damage, the air conditioningsystem in your vehicle shouldonly be serviced by trained andcertified technicians.
