Mode selection
The mode selection button controls
the direction of the air flow through
the ventilation system.
Air can be directed to the floor, dash-
board outlets, or windshield. Five
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. 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, C, D, E, F)
Air flow is directed towards the face
and the floor.
Floor-Level (A, C, D, E, F)
Most of the air flow is directed to the
floor, with a small amount of the air
being directed to the windshield and
side window defrosters. Floor/Defrost-Level
(A, C, D, E, F)
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)

Air intake control
The air intake control is used to
select the outside (fresh) air position
or recirculated air position.
To change the air intake control posi-
tion, press the control button. 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

enters the vehicle from
outside and is heated or
cooled according to the
function selected.
✽ ✽ NOTICE
Prolonged operation of the heater in
the recirculated air position (without
air conditioning selected) may cause
fogging of the windshield and side win-
dows and the air within the passenger
compartment may become stale. In
addition, prolonged use of the air con-
ditioning 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 is operat-
ing, the outside (fresh) air will be
selected automatically for ventilating
the car. Then, if you select the recir-
culated air position, the outside
(fresh) air will be selected automati-
cally after 3 minutes.
If you close the sunroof, the intake
mode will be changed to the previous
selected mode.

loss of vehicle control. Set the
air intake control to the outside
(fresh) air position as much as
possible while driving.

WARNING- Sleeping with AC 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.

If the windshield fogs up, set the mode to the or position. 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 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 outside air or recirculated air posi-
tion.
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 insure 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 shall
be certified (and labeled) as meet-
ing 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 elec-
trical equipment, air conditioning
should only be used with the win-
dows 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 on the inside surface of the windows on
rainy or humid days, decrease the
humidity inside the vehicle by oper-
ating 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 AC
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 accu-
mulation on the inside of the wind-
shield even when the outside (fresh)
air position is selected. If this hap-
pens, we recommend that the cli-
mate control air filter be 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 or
rough roads, more frequent cli-
mate control air filter inspections
and changes are required.
• When the air flow rate suddenly decreases, we recommend that 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 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- AC Repair
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.
