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
the function selected.
Outside (fresh) air position If the recirculated airposition is not selected
or turned off, air enters
the vehicle from outside
and is heated or cooled
according to the function
selected. Prolonged operation of the heater in
the recirculated air position (without air
conditioning selected) may cause fog-
ging of the windshield and side win-
dows, and the air within the passenger
compartment may become stale.
In addition, prolonged operation of
the air conditioning with the recircu-
lated air position selected will result
in excessively dry air in the passen-
ger compartment.
WARNING- Reduced
Visibility
Continuous use of the climate
control system in the recirculat-
ed air position may allow
humidity to increase inside the
vehicle which may fog the glass
and obscure visibility.
WARNING- Sleeping with A/C 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.
WARNING- Recirculated air
Continued use of the climate
control system in the recirculat-
ed 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 driving.

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 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.

WINDSHIELD DEFROSTING AND DEFOGGING
For maximum defrosting, set the
temperature control all the way to
the 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 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.Manual climate control system
To defog inside windshield
1. Select any fan speed except "0" position.
2. Select desired temperature.

and the windshield could cause
the outer surface of the wind-
shield to fog up, causing loss of
visibility.
