lation system.Air can be directed to the floor, dashboard
outlets, or windshield. Six symbols are used
to represent MAX A/C, Face, Bi-Level,
Floor, Floor-Defrost and Defrost air position.
The MAX A/C mode is used to cool the
inside of the vehicle faster.MAX A/C-Level (B,D)
Air is discharged through the face level
vents.
If the “MAX A/C” mode is selected, the
A/C will turn on automatically and
“Recirculation” mode will be activated.
Face-Level (B,D)
Air flow is directed toward the upper body
and face. Additionally, each outlet can be
controlled to direct the air discharged
from the outlet.
Bi-Level (B, D, C)
Air flow is discharged towards the face
and floor.
Floor-Level (C, A, D)
Most of the air flow is directed to the
floor, with a small amount of the air being
directed to the windshield and side win-
dow defroster.
Floor/Defrost-Level (A, C, D)
Most of the air flow is directed to the floor
and the windshield with a small amount
directed to the side window defrosters.
Defrost-Level (A, D)
Most of the air flow is directed to the
windshield with a small amount of air

4Instrument panel vents
The outlet port can be opened or closed
separately using the horizontal thumb-
wheel. To close the vent, rotate it to the
far left position. To open the vent, rotate it
right to the desired position.
Also, you can adjust the direction of air
delivery from these vents using the vent
control lever as shown.
D230102AFDTemperature controlThe temperature control knob allows you
to control the temperature of the air flow-
ing from the ventilation system. To
change the air temperature in the pas-
senger compartment, turn the knob to
the right position for warm air or left posi-
tion for cooler air.

Recirculated air position The indicator light on the but-
ton is illuminated when the
recirculated air position is
selected.
With the recirculated air posi- tion selected, air from pas-
senger compartment will be
drawn through the heating
system and heated or cooled
according to the function
selected.
Outside (fresh) air position The indicator light on the but-
ton is illuminated when the
outside (fresh) air position is
selected.
With the outside (fresh) air
position selected, air enters
the vehicle from outside and
is heated or cooled according
to the function selected.
✽ ✽NOTICEProlonged operation of the heater in the
recirculated air position (without air
conditioning selected) may cause fog-
ging of the windshield and side windows
and the air within the passenger com-
partment may become stale.
In addition, prolonged use of the air
conditioning with the recirculated air
position selected will result in excessive-
ly dry air in the passenger compart-
ment.
WARNING
• Continued climate control system
operation in the recirculated air
position may allow humidity to
increase inside the vehicle which
may fog the glass and obscure
visibility.
Do not sleep in a vehicle with the air conditioning or heating sys-
tem on. It may cause serious
harm or death due to a drop in the
oxygen level and/or body temper-
ature.
Continued climate control system operation in the recirculated 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 driv-
ing.

4D230104AUNFan speed controlThe ignition switch must be in the ON
position for fan operation.
The fan speed control knob allows you to
control the fan speed of the air flowing
from the ventilation system. To change
the fan speed, turn the knob to the right
for higher speed or left for lower speed.
Setting the fan speed control knob to the
“0” position turns off the fan.

Operation Tips
To keep dust or unpleasant fumes fromentering the car 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 driver
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 condi-
tioning system, and adjust temperature
control to desired temperature.
D230503AMGAir conditioning (if equipped) All KIA Air Conditioning Systems are
filled with environmentally friendly
R-134a refrigerant which does not dam-
age 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 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 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 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 performance.
When using the air conditioning sys- tem, you may notice clear water drip-
ping (or even puddling) 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 provides
maximum cooling, however, 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 opera-
tion characteristics.
D230300AMG-ECClimate 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 vehi-
cle 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 hap-
pens, have the climate control air filter
replaced by an authorized KIA dealer.
✽ ✽ NOTICE• If the car is being driven in severe
conditions such as dusty, rough roads,
more frequent climate control air fil-
ter inspections and changes are
required.
• When the air flow rate is suddenly decreased, the system should be
checked at an authorized KIA dealer.

D230400AUNChecking 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 negative
influence on the air conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by an
authorized KIA dealer.✽ ✽NOTICEIt is important when servicing the air
conditioning system that the correct
type and amount of oil and refrigerant is
used. Otherwise, damage to the com-
pressor and abnormal system operation
may occur.
WARNING
The air conditioning system should
be serviced by an authorized KIA
dealer. Improper service may cause
serious injury to the person per-
forming the service.
