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 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.

CAUTION -

Excessive A/C
Use

When using the air conditioning
system, monitor the tempera-
ture gauge closely while driving
up hills or in heavy traffic when
outside temperatures are high.
Air conditioning system opera-
tion may cause engine over-
heating. Continue to use the
blower fan but turn the air con-
ditioning system off if the tem-
perature gauge indicates engine
overheating.

CAUTION

When opening the windows in
humid weather, air conditioning
may create water droplets
inside the vehicle. Since exces-
sive water droplets may cause
damage to electrical equipment,
air conditioning should only be
used with the windows closed.

Features of your vehicle

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 every 15,000

miles or once a year.
If the vehicle is being driven in
severe conditions such as dusty or
rough roads, more frequent air
conditioner 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.
