Features of your vehicle
Automatic Ventilation (if equipped)
When the ignition is ON or when the
engine is running and the outside
temperature is below 59°F (15°C),
the automatic ventilation feature will
activate if the recirculated air intake
position is selected for more than 5
minutes while A/C is off and floor
mode is selected. In this condition
the air intake position will automati-
cally switch to the outside (fresh) air
intake position.
To cancel or reset the Automatic
Ventilation
When the air conditioning system is
on, select Face Level mode and
while pressing the A/C button, press
the recirculated air position button
five times within three seconds.
When the automatic ventilation is
canceled, the indicator blinks 3
times. When the automatic ventila-
tion is activated, the indicator blinks
6 times.

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
orposition. 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 more 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.

Use
When using the air conditioningsystem, monitor the tempera-ture gauge closely while drivingup hills or in heavy traffic whenoutside temperatures are high.Air conditioning system opera-tion may cause engine over-heating. Continue to use theblower fan but turn the air con-ditioning system off if the tem-perature gauge indicates engineoverheating.
CAUTION
When opening the windows inhumid weather, air conditioningmay create water dropletsinside the vehicle. Since exces-sive water droplets may causedamage to electrical equipment,air conditioning should only beused with the windows 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 at least a few
minutes to ensure maximum sys-
tem performance. 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.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.

cle may differ from the illustration.Power outlet
The power outlet is designed to pro-
vide 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
accessory plug after use. Using the
accessory plug for prolonged peri-
ods of time with the engine off
could cause the battery to dis-
charge.
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 out-
let. These devices may cause
excessive audio static and malfunc-
tions in other electronic systems or
devices used in your vehicle.
Push the plug in as far as it will go. If good contact is not made, the
plug may overheat and the fuse
may open.
CAUTION- Vanity mirror
lamp
If you use the vanity mirrorlamp, turn off the lamp beforereturning the sunvisor to itsoriginal position, otherwise itcould result in battery dis-charge and possible sunvisordamage.
