Driving your vehicle

Air conditioning system opera-
tion 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 win-

dows on rainy or humid days, decrease
the humidity inside the vehicle by oper-
ating the air conditioning system.

• During air conditioning system opera-

tion, you may occasionally notice a
slight change in engine speed at idle
as the air conditioning compressor
cycles. This is a normal system opera-
tion characteristic.

• Use the air conditioning system every

month if only for a few minutes to
ensure maximum system perform-
ance.

• When using the air conditioning sys-

tem, you may notice clear water drip-
ping (or even pudding) on the ground
under the passenger side of the vehi-
cle. This is a normal system operation
characteristic.

• The air conditioning system includes a

function that automatically turns the air
conditioning compressor off if engine
coolant temperature approaches an
over heating level. The air conditioning
compressor operation will resume
once engine coolant temperature
returns to the normal range. Also, the
air conditioning compressor is auto-
matically turned off for a few seconds
when the accelerator is fully depressed
(wide open throttle).

• When operating the air conditioning

system use the outside (fresh) air posi-
tion.

• Operating the air conditioning system

in the recirculated air position does
provide maximum cooling, however,
continual operation in this mode may
cause the air inside the vehicle to
become stale.

Checking the amount of air con-
ditioner refrigerant and compres-
sor lubricant

When the amount of refrigerant is low,
the performance of the air conditioning is
reduced. Overfilling also has a bad influ-
ence on the air conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by an
authorized Kia dealer.

✽

NOTICE

When the performance of the air condi-
tioning system is reduced it is important
that the correct type and amount of oil
and refrigerant is used. Otherwise,
damage to the compressor and abnor-
mal system operation may occur.

CAUTION

The air conditioning system should
be serviced by an authorized Kia
dealer. Improper service may cause
serious injury.
