Features of your vehicle

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.

Fan speed control

The fan speed can be set to the
desired speed by operating the fan
speed control button.
To change the fan speed, press (

)

the button for higher speed, or push
(

) the button for lower speed. To

turn the fan speed control off, press
the front blower OFF button.

Air conditioning

Press the A/C button to turn the air
conditioning system on (indicator
light will illuminate).
Press the button again to turn the air
conditioning system off.

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.

WARNING -

Sleeping with
AC on

Do not sleep in a vehicle with
the air conditioning or heating
on as this may cause serious
harm or death due to a drop in
the oxygen level and/or body
temperature.

Features of your vehicle

System operation

Ventilation

1.Set the mode to the

position.

2.Set the air intake control to the out-

side (fresh) air position.

3.Set the temperature control to the

desired position.

4.Set the fan speed control to the

desired speed.

Heating

1.Set the mode to the

position.

2.Set the air intake control to the out-

side (fresh) air position.

3.Set the temperature control to the

desired position.

4.Set the fan speed control to the

desired speed.

5.If dehumidified heating is desired,

turn the air conditioning system (if
equipped) on.

• 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 (if equipped)

All Kia Air Conditioning Systems are
filled with R-1234yf refrigerant.
1.Start the engine. Press the air con-

ditioning button.

2.Set the mode to the

position.

3.Set the air intake control to the out-

side air or recirculated air position.

4.Adjust the fan speed control and

temperature control to maintain
maximum comfort.

• When maximum cooling is desired,

set the temperature control to the
extreme left position, set the mode
control to the MAX A/C position,
then set the fan speed control to
the highest speed.

✽

✽

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 electrical equip-
ment, air conditioning should only be
used with the windows 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 inside of

the windows on rainy or humid
days, decrease the humidity inside
the vehicle by operating 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 A/C
Use

When using the air conditioning
system, monitor the tempera-
ture gauge closely while driving
up hills or in heavy traffic when
outside temperatures are high.
Air conditioning system opera-
tion may cause engine over-
heating. Continue to use the
blower fan but turn the air con-
ditioning system off if the tem-
perature gauge indicates engine
overheating.

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 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 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.

Example

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

It is important that the correct
type and amount of oil and refrig-
erant is used, otherwise damage
to the vehicle may occur. To pre-
vent damage, the air conditioning
system in your vehicle should
only be serviced by trained and
certified technicians.

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.

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.

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
