Prolonged operation of the heater in
the recirculated air position (without
air conditioning selected) may cause
fogging of the windshield and side
windows and the air within the pas-
senger compartment may become
stale.
In addition, prolonged use of the air
conditioning 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 operates,
the outside (fresh) air will be select-
ed automatically for ventilating the
car. Then, if you select the recirculat-
ed air position, the outside (fresh) air
will be selected automatically after 3
minutes.
If you close the sunroof, the intake
mode will be changed to the previous
selected mode.

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, have the climate control air fil-
ter replaced by an authorized Kia
dealer.
✽ ✽NOTICE
• Replace the filter every 15,000
miles or once a year.
If the vehicle is being driven in
severe conditions such as dusty or
rough roads, more frequent air
conditioner filter inspections and
changes are required.
• When the air flow rate suddenly decreases, 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 condi-
tioning is reduced. Overfilling also
has a negative impact on the air con-
ditioning system.
Therefore, if abnormal operation is
found, have the system inspected by
an authorized Kia dealer.

Features of your vehicle
For maximum defrosting, set thetemperature 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 posi-
tion.
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.Automatic climate control
system
To defog inside windshield
1. Set the fan speed to the desired position.
2. Select desired temperature.
3. Press the defroster button ( ).

temperature.
WINDSHIELD DEFROSTING AND DEFOGGING
WARNING - Windshield
heating
Do not use the or posi-
tion during cooling operation in
extremely humid weather. The
difference between the temper-
ature of the outside air and the
windshield could cause the
outer surface of the windshield
to fog up, causing loss of visi-
bility. In this case, set the mode
selection to the position
and fan speed control to the
lower speed.

indicates that the defogging logic is
canceled or returned to the pro-
grammed status.
If the battery has been discharged or
disconnected, it resets to the defog
logic status.
Auto defogging system (if equipped)
Auto defogging reduces the probabil-
ity of fogging up the inside of the
windshield by automatically sensing
the moisture of inside the windshield.
The auto defogging system operates
when the heater or air conditioning is
on. This indicator illuminates
when the auto defogging
system senses the mois-
ture on the inside of the
windshield and operates.
If more moisture is in the vehicle,
higher steps operate as follow. For
example if auto defogging does not
defog inside the windshield at step 1
Outside air position, it tries to defog
again at step 2 Operating the air con-
ditioning.
Step 1 : Outside air position
Step 2 : Operating the air condition- ing
Step 3 : Blowing air flow toward the windshield
Step 4 : Increasing air flow toward the windshield

What to do in an emergency
IF THE ENGINE OVERHEATS
If your temperature gauge indicates
overheating, you will experience a
loss of power, or hear loud pinging or
knocking, the engine is probably too
hot. If this happens, you should:
1. Turn on the emergency warningflasher and stop in a safe place.
Move the shift lever to P (Park)
and engage the parking brake.
2. If hot steam does not come out from the engine room, carefully
open the engine room and check
whether the water pump connec-
tor is properly engaged. If the con-
nector is not properly engaged,
stop the engine immediately and
properly engage the connector.
Then, turn the engine on.
3. Turn on the air conditioner. 4. If the “HEV Warning” light turns on
in the driver instrument cluster, or
engine coolant or hot steam emits
from the engine coolant filler, stop
the engine immediately. Then, call
the nearest authorized Kia dealer
for assistance. If the “Engine
Warning” light remains illuminated
or the engine coolant is not flowing
out, keep the engine running.
Open the engine hood for ventila-
tion to help cool down the engine. 5. Check whether the engine coolant
temperature is low enough by
checking its temperature. If the
engine coolant level is low, please
check the connecting parts
between the radiator hose, heater
hose, and water pump for any
signs of leakage. When there is no
sign of leakage, please refill the
engine coolant. If causes and
signs of engine overheating such
as warning light illumination,
engine coolant leakage, or cooling
fan malfunction are found, stop the
vehicle the earliest. Then, call the
nearest authorized Kia dealer for
assistance.
WARNING
While the engine is running,
keep hair, hands and clothing
away from moving parts such
as the fan and drive belts to pre-
vent injury.
