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
Kia Air Conditioning Systems are
filled with environmentally friendly R-
134a 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 outside air or recirculated air posi-
tion.
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, then set the
fan speed control to the highest
speed.CAUTION- A/C use
When using the air condition- ing system, monitor the tem-perature gauge closely whiledriving up hills or in heavy traf-fic when outside temperaturesare high. Air conditioning sys-tem operation may causeengine overheating. Continueto use the blower fan but turnthe air conditioning system offif the temperature gauge indi-cates engine overheating.
When opening the windows in humid weather air condition-ing may create water dropletsinside the vehicle. Sinceexcessive water droplets maycause damage to electricalequipment, air conditioningshould only be used with thewindows closed.

Air conditioning system operation tips
If the vehicle has been parked indirect 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.
If you operate air conditioner excessively, the difference between
the temperature of the outside air
and that of the windshield could
cause the outer surface of the
windshield to fog up, causing loss
of visibility. In this case, set the
mode selection knob or button to
the position and fan speed
control to the lower speed.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 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 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.
WARNING
The air conditioning system for
the Hybrid vehicle should be
serviced by an authorized Kia
dealer. The Hybrid air condition-
ing system is connected to the
high voltage system and
requires special fluids, tools
and service procedures.
Improperly servicing the Hybrid
air conditioning system could
result in electrical shock, seri-
ous injury, or even death.
WARNING
Because the refriger-
ant is at very high
pressure, the air con-
ditioning 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, oth-
erwise damage to the vehicle
and personal injury may occur.
CAUTION- Proper Oil &
Refrigerant
It is important that the correcttype 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.

mode to the floor-defrost position.
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 sys-
tem

Features of your vehicle
The indicator light in the air intake
control button will blink 3 times with
0.5 second of interval. It indicates that
the defogging logic is canceled or
returned to the programmed status.
If the battery has been discharged or
disconnected, it resets to the defog
logic status.Auto defogging system (if equipped)
Auto defogging reduces the probabil-
ity of fogging up the inside of the
windshield by automatically sensing
the moisture 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 inside the windshield
and operates.
If more moisture is in the vehicle,
higher steps operate as follows. 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 Blowing air toward
the windshield.
Step 1 : Operating the air conditioning
Step 2 : Outside air position
Step 3 :Blowing air toward the wind-
shield
Step 4 : Increasing air flow toward the windshield
