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.

Driving your vehicle60 4Mode selection button The mode selection button controls the
direction of the air flow through the venti-
lation system.
The air flow outlet port changes as fol-
lows:Face position
Air flow is directed toward the
upper body and face.
Additionally, each outlet can
be controlled to direct the air
discharged from the outlet.
(outlet port: B, D)
Face - floor position
Air flow is directed towards
the face and the floor. The air
to the floor is warmer than
the air to the face
(except when the tempera-
ture control is set to the
extreme cold position).
(outlet port: B, C, E, D)
Floor position
Most of the air flow is direct-
ed to the floor, with a small
amount of the air being
directed to the windshield
and side window defroster.
(outlet port:
C, E, A
, D)
Floor - defrost position
Most of the air flow is direct-
ed to the floor and the wind-
shield with a small amount
directed to the side window
defrosters.
(outlet port: A, C, E, D)
Defrost button Most of the air flow is directed to the
windshield with a small amount of air
directed to the side window defrosters.

Instrument panel ventsIf air flow control is not satisfactory, check
the instrument panel vents. The outlet
port (B, D) can be opened or closed sep-
arately using the thumbwheel.
Also, you can adjust the direction of air
delivery from these vents using the vent
control lever as shown.
The air from outlet port (D) flows at any
mode. Close the ventilation outlets using
the thumbwheel to block the air flow if
you do not want the air.

Driving your vehicle62 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 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 on.
This is a normal system operation
characteristics.
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
characteristics. 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.
✽ ✽
NOTICEWhen using the air conditioning system,
monitor the temperature gauge closely
while driving up hills or in heavy traffic
when outside temperatures are high. Air
conditioning system operation may
cause engine overheating. Continue to
use the blower fan but turn the air con-
ditioning system off if the temperature
gauge indicates engine overheating.
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 Kia
dealer. Improper service may cause
serious injury.

perature control to the extreme
right/hot position and the fan speed
control to the highest speed.
If warm air to the floor is desired while
defrosting or defogging, set the mode
to the floor-defrost position.
Before driving, clear all snow and ice
from the windshield, rear window, out-
side rear view mirrors, and all side win-
dows.
Clear all snow and ice from the hood
and air inlet in the cowl grill to improve
heater and defroster efficiency and to
reduce the probability of fogging up
inside of the windshield.
WINDSHIELD DEFROSTING AND DEFOGGING
CAUTION
- Windshield
heating
Do not use the or position
during cooling operation in
extremely humid weather. The dif-
ference between the temperature of
the outside air and that of the wind-
shield could cause the outer sur-
face of the windshield to fog up,
causing loss of visibility. In this
case, set the mode selection knob
to the position and fan speed
control knob to the lower speed.
