CLIMATE CONTROL SYSTEM

System operation
Ventilation
1. Set the mode to the position.
2. Set the air intake control to the outside (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 outside (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.
Operation tips
• To keep dust or unpleasant fumes from entering the vehicle through the
ventilation system, temporarily set
the air intake control to the recircula‐
ted 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 driver alert and comforta‐
ble.
• 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 obstruc‐
tions.
• 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.
• If the windshield fogs up, set the mode to the
or position.
CAUTION
Operating the blower when the igni‐tion switch is in the ON positioncould cause the battery to discharge.Operate the blower when the engineis running.
Air conditioning
Kia air conditioning systems are filled
with R-134a or R-1234yf refrigerant. 1. Start the hybrid system. Push the air conditioning button.
2. Set the mode to the
position.
3. Set the air intake control to the outside air or recirculated air posi‐
tion.
4. Adjust the fan speed control and temperature control to maintain
maximum comfort.

Climate control air filter
06.-
A: Outside air
B: Recirculated air
C: Climate control air filter
D: Blower
E: Evaporator core
F: Heater core The climate control air filter installed
behind the glove box filters the dust or other pollutants that come into the ve‐
hicle 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 de‐
crease, resulting in moisture accumula‐ tion on the inside of the windshield
even when the outside (fresh) air posi‐
tion is selected. If this happens, we rec‐ ommend that the climate control air fil‐
ter be replaced by an authorized Kia
dealer.NOTICE
•Replace the filter according to the

Air intake control
This is used to select the outside
(fresh) air position or recirculated air position.
To change the air intake control posi‐
tion, push the control button.
Recirculated air position
With the recirculated air position selected, air from
the passenger compart‐ment will be drawnthrough the heating sys‐
tem and heated or cooled
according to the functionselected.
Outside (fresh) air position
With the outside (fresh) air position selected, air
enters the vehicle fromoutside and is heated or
cooled according to thefunction selected.
NOTICE
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.
WARNING
•Continue using the climate controlsystem in the recirculated air posi‐tion may allow humidity to in‐crease inside the vehicle whichmay fog the glass and obscure vis‐ibility.
•Do not sleep in a vehicle with theair conditioning or heating systemon. It may cause serious harm ordeath due to a drop in the oxygenlevel and/or body temperature.
•Continue using the climate controlsystem in the recirculated air posi‐tion can cause drowsiness orsleepiness, and loss of vehicle con‐trol. Set the air intake control tothe outside (fresh) air position asmuch as possible while driving.

To defog inside windshield
0+'
1. Set the fan speed to the desiredposition.
2. Select the desired temperature.
3. Press the defroster button (
).
4. The air conditioning will turn on ac‐ cording to the detected ambient
temperature and outside (fresh) air
position will be selected automati‐
cally. If the air conditioning and outside
(fresh) air position are not selected au‐
tomatically, adjust the corresponding
button manually. If the
position is
selected, lower fan speed is adjusted to a higher fan speed.
To defrost outside windshield
0+'
1. Set the fan speed to the highest position.
2. Set the temperature to the ex‐ treme hot (HI) position.
3. Press the defroster button
. 4. The air conditioning will turn on ac‐
cording to the detected ambient
temperature and outside (fresh) air
position will be selected automati‐
cally.
Operation tips
• For maximum defrosting, set the temperature 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,
outside rear view mirrors, and all side windows.
• Clear all snow and ice from the hood and air inlet in the cowl grill to im‐
prove heater and defroster efficiency
and to reduce the probability of fog‐
ging up the inside of the windshield.
