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.

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 theupper 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 towardsthe 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.

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.

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 causeserious injury.
