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 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.

✽ ✽
NOTICE
• Replace the filter according to the
Maintenance Schedule.
If the vehicle is being driven in
severe conditions such as dusty or
rough roads, more frequent cli-
mate control air 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.
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
explosion may result. To reduce
the risk of serious injury or
death, the air conditioning sys-
tem in your vehicle should only
be serviced by trained and cer-
tified technicians.
