Operation Tips
To prevent dust or unpleasant fumesfrom 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 irrita-
tion has passed to keep fresh air in the
vehicle. This will help keep the driver
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 condi-
tioning system, and adjust the temper-
ature control to desired temperature.Air conditioning (if equipped)
All Kia Air Conditioning Systems are
filled with environmentally friendly
R-134a refrigerant which does not dam-
age the ozone layer.
1. Start the engine. Push the air condi- tioning button.
2. Set the mode to the position.
3. Set the air intake control to the recir- culated air position. However, pro-
longed operation of the reticulated air
position will excessively dry the air. In
this case, change the air position.
4. Adjust the fan speed control and tem- perature 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
• While using the air conditioning sys-
tem, monitor the temperature gauge
closely while driving up hills or in
heavy traffic when outside tempera-
tures are high. Air conditioning sys-
tem operation may cause engine over-
heating. Continue to use the blower
fan but turn the air conditioning sys-
tem off if the temperature gauge indi-
cates engine overheating.
• While opening the windows in humid weather air conditioning may create
water droplets inside the vehicle.
Since excessive water droplets may
cause damage to electrical equipment,
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 vehi-
cle by operating 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.
This is a normal system operation
characteristic.
Use the air conditioning system every month only for a few minutes to ensure
maximum system performance.
When using the air conditioning sys- tem, you may notice clear water drip-
ping (or even puddling) on the ground
under the passenger side of the vehi-
cle. This is a normal system operation
characteristic. Operating the air conditioning system
in the recirculated air position provides
maximum cooling, however, 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 opera-
tion characteristic.
Climate control air filter
The climate control air filter installed
behind the glove box filters the dust or
other pollutants that come into the vehi-
cle 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 hap-
pens, have the climate control air filter
replaced by an authorized Kia dealer.

air conditioning are controlled automati-
cally according to certain conditions such
as or position. To cancel or
return to the defogging logic, do the fol-
lowings:
Automatic climate control system
1. Turn the engine start/stop button to theON position.
2. Select the defroster position pressing the defroster button ( ).
3. While pressing the air conditioning button (A/C), press the air intake con-
trol button ( ) at least 5 times with-
in 3 seconds.
The A/C display blinks 3 times with 0.5
second of interval. It indicates that the
defogging logic is canceled or returned to
the programmed status.
If the battery has been discharged or dis-
connected, it resets to the defog logic
status.

Power outlet (if equipped)
The power outlet is designed to provide
power for mobile telephones or other
devices designed to operate with vehicle
electrical systems. The devices should
draw less than 10 amps with the engine
running.
Use the power outlet only when the
engine is running and remove the acces-
sory plug after use. Using the accessory
plug for prolonged periods of time with
the engine off could cause the battery to
discharge.
Only use 12V electric accessories which
are less than 10A in electric capacity.
Adjust the air-conditioner or heater to the
lowest operating level when using the
power outlet. Close the cover when not in use.
Some electronic devices can cause elec-
tronic interference when plugged into a
vehicle’s power outlet. These devices
may cause excessive audio static and
malfunctions in other electronic systems
or devices used in your vehicle.
CAUTION - Vanity mirror
lamp
Close the vanity mirror cover
securely and return the sunvisor toits original position after use. If thevanity mirror is not closed securely,the lamp will stay on and could result in battery discharge and pos-sible sunvisor damage.

How vehicle audio works
AM and FM radio signals are broadcast
from transmitter towers located around
your city. They are intercepted by the
radio antenna on your vehicle. This signal
is then received by the radio and sent to
your vehicle speakers.
When a strong radio signal has reached
your vehicle, the precise engineering of
your audio system ensures the best pos-
sible quality reproduction. However, in
some cases the signal coming to your
vehicle may not be strong and clear. This
can be due to factors such as the dis-
tance from the radio station, closeness of
other strong radio stations or the pres-
ence of buildings, bridges or other large
obstructions in the area. AM broadcasts can be received at
greater distances than FM broadcasts.
This is because AM radio waves are
transmitted at low frequencies. These
long, low frequency radio waves can fol-
low the curvature of the earth rather than
travelling straight out into the atmos-
phere. In addition, they curve around
obstructions so that they can provide bet-
ter signal coverage.
