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 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 on. This is a normal system
operating 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 puddling) on the ground
under the passenger side of the vehi-
cle. This is a normal system operating
characteristic.
• 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.
CAUTION
When using the air conditioning
system, monitor the temperature
gauge closely while driving up hills
or in heavy traffic when outside tem-
peratures are high. Air conditioning
system operation may cause engine
overheating. Continue to use the
blower fan but turn the air condi-
tioning system off if the temperature
gauge indicates engine overheat-
ing.
CAUTION
The air conditioner refrigerant con-
tainer is highly pressurized.
Therefore it should be serviced by
an authorized Kia dealer. Improper
service may cause serious injury.
CAUTION
When the performance of the air
conditioning system is reduced it is
important that the correct type and
amount of oil and refrigerant is
used. Otherwise, damage to the
compressor and abnormal system
operation may occur.
