Malfunction indicator
(if equipped)This indicator light is part of the Engine
Control System which monitors various
emission control system components. If
this light illuminates while driving, it indi-
cates that a potential problem has been
detected somewhere in the emission
control system.
Generally, your vehicle will continue to be
drivable and will not need towing, but
have the system checked by an author-
ized Kia dealer as soon as possible.✽ ✽NOTICEA loose fuel filler cap may cause the On
Board Diagnostic System Malfunction
Indicator Light ( ) in the instrument
panel to illuminate unnecessarily.
Always make sure that the fuel filler cap
is tight.
✽ ✽NOTICE• Prolonged driving with the Emission
Control System Malfunction
Indicator Lamp ( ) illuminated
may cause damage to the emission
control systems which could effect dri-
vability and/or fuel economy.
•If the

✽ ✽
NOTICE• When using the air conditioning sys-
tem, monitor the temperature gauge
closely while driving up hills or in
heavy traffic when outside tempera-
tures are high. Air conditioning sys-
tem operation may cause engine over-
heating. Continue to use the blower
fan but turn the air conditioning sys-
tem off if the temperature gauge indi-
cates engine overheating.

4Air 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 as the
air conditioning compressor cycles.
This is a normal system operation
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. 
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 lubricantWhen 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.✽ ✽
NOTICEWhen 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, dam-
age to the compressor and abnormal
system operation may occur.
CAUTION
The air conditioning system should
be serviced by an authorized Kiadealer. Improper service may cause serious injury to the person per-forming the service.
