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
Kia Air Conditioning Systems are
filled with environmentally friendly R-
134a 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 outside air or recirculated air posi-
tion.
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, then set the
fan speed control to the highest
speed.CAUTION- A/C use
When using the air condition- ing system, monitor the tem-perature gauge closely whiledriving up hills or in heavy traf-fic when outside temperaturesare high. Air conditioning sys-tem operation may causeengine overheating. Continueto use the blower fan but turnthe air conditioning system offif the temperature gauge indi-cates engine overheating.
When opening the windows in humid weather air condition-ing may create water dropletsinside the vehicle. Sinceexcessive water droplets maycause damage to electricalequipment, air conditioningshould only be used with thewindows closed.

Air conditioning system operation tips
If the vehicle has been parked indirect 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.
If you operate air conditioner excessively, the difference between
the temperature of the outside air
and that of the windshield could
cause the outer surface of the
windshield to fog up, causing loss
of visibility. In this case, set the
mode selection knob or button to
the position and fan speed
control to the lower speed.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.

engine is running and remove the
accessory 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
electronic interference when plugged
into a vehicle’s power outlet. These
devices may cause excessive audio
static and malfunctions in other elec-
tronic systems or devices used in
your vehicle.

Driving your vehicle
Be sure the exhaust system
does not leak.
The exhaust system should be
checked whenever the vehicle is
raised to change the oil or for any
other purpose. If you hear a change
in the sound of the exhaust or if you
drive over something that strikes the
underneath side of the vehicle, have
the exhaust system checked as soon
as possible by an authorized Kia
dealer.
WARNING - Engineexhaust
Do not inhale exhaust fumes or
leave your engine running in an
enclosed area for a prolonged
time.
Exhaust fumes contain carbon
monoxide, a colorless, odorless
gas that can cause uncon-
sciousness and death by
asphyxiation.
WARNING - Open trunk
Do not drive with the trunk
open.
Poisonous exhaust gases can
enter the passenger compart-
ment. If you must drive with the
trunk open proceed as follows:
1. Close all windows.
2. Open side vents.
3. Set the air intake control at "Fresh", the air flow control at
"Floor" or "Face" and the fan
at the highest speed.
