The indicator light on the but-
ton is illuminated when the
recirculated air position is
selected.
Use this position only for
short period with the recircu-
lated air position selected, air
from passenger compart-
ment will be drawn through
the climate control system
and heated or cooled accord-
ing to the function selected.
Outside (fresh) air position
With the outside (fresh) air
position selected, air enters
the vehicle from outside and
is heated or cooled according
to the function selected.
✽ ✽
NOTICEProlonged use of the air conditioning
with the “recirculated air position”
selected, will result in excessively dry air
in the passenger compartment.
WARNING
- Recirculated
air
 Continued climate control system
operation in the recirculated air
position may allow humidity to
increase inside vehicle which
may fog the glass and obscure
visibility.
 Do not sleep in a vehicle with air
conditioning or heating system
on. It may cause serious harm or
death due to a drop in the oxygen
level and/or body temperature.
 Continued climate control system
operation in the recirculated air
position can slightly reduce oxy-
gen levels which can lead to
cause drowsiness or sleepiness,
and loss of vehicle control. Set
the air intake control to the out-
side (fresh) air position as much
as possible while driving.

Air conditioning (if equipped) All Kia Air Conditioning Systems are
filled with environmentally friendly
R-134a refrigerant which is not damag-
ing to the ozone layer.
1. Start the engine. Push the air condi-
tioning button.
2. Set the mode to the position.
3. Set the air intake control to the outside air or recirculated air position. 4. Adjust the fan speed control and tem-
perature 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 using the air conditioning sys-
tem, monitor the temperature gauge
closely while driving up hills or in
heavy traffic when outside tempera-
tures are high. Air conditioning sys-
tem operation may cause engine over-
heating. Continue to use the blower
fan but turn the air conditioning sys-
tem off if the temperature gauge indi-
cates engine overheating.
• 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 equipment,
air conditioning should only be run
with the windows closed.

4Air conditioning system opera-
tion 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 win-
dows on rainy or humid days, decrease
the humidity inside the vehicle by oper-
ating the air conditioning system.
 During air conditioning system opera-
tion, you may occasionally notice a
slight change in engine speed as the
air conditioning compressor cycles.
This is a normal system operation
characteristic.
 Use the air conditioning system every
month if only for a few minutes to
ensure maximum system perform-
ance.
 When using the air conditioning sys-
tem, you may notice clear water drip-
ping (or even pudding) on the ground
under the passenger side of the vehi-
cle. This is a normal system operation
characteristic. 
Operating the air conditioning system
in the recirculated air position does
provide maximum cooling, however,
continual operation in this mode may
cause the air inside the vehicle to
become stale.
Checking the amount of air con-
ditioner refrigerant and compres-
sor lubricantWhen the amount of refrigerant is low,
the performance of the air conditioning is
reduced. Overfilling also has a bad influ-
ence on the air conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by an
authorized Kia dealer.✽ ✽
NOTICEWhen the performance of the air condi-
tioning system is reduced it is important
that the correct type and amount of oil
and refrigerant is used. Otherwise, dam-
age to the compressor and abnormal
system operation may occur.
CAUTION
The air conditioning system should
be serviced by an authorized Kiadealer. Improper service may cause serious injury to the person per-forming the service.
