Features of your vehicle
Climate control air filter
The climate control air filter installed
behind the glove box filters the dust
and other pollutants that come into
the vehicle from the outside through
the heating and air conditioning sys-
tem. If dust or other pollutants accu-
mulate in the filter over a period of
time, the air flow from the air vents
may decrease, resulting in moisture
accumulation on the inside of the
windshield even when the outside
(fresh) air position is selected. If this
happens, have the climate control air
filter 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,
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 con-
ditioning is reduced. Overfilling also
has a negative influence on the air
conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by
an authorized Kia dealer.
The air conditioning system should
be serviced by an authorized Kia
dealer.
CAUTION - Compressor
damage
It is important that the correct
type and amount of oil andrefrigerant is used. Otherwise,damage to the compressor andabnormal system operation mayoccur.

NORMAL MAINTENANCE SCHEDULE
The following maintenance services must be performed to ensure good emission control and performance. Keep
receipts for all vehicle emission services to protect your warranty. Where both mileage and time are shown, the fre-
quency of service is determined by whichever occurs first.
*1: If TOP TIER Detergent Gasoline is not available, one bottle of additive is recommended. Additives are available from yourauthorized Kia dealer along with information on how to use them. Do not mix other additives.
*
2: Fuel filter & Fuel tank air filter are considered to be maintenance free\
but periodic inspection is recommended for this mainte- nance schedule depends on fuel quality. If there are some important safety matters like fuel flow restriction, surging, loss of
power, hard starting problem etc, replace the fuel filter immediately regardless of maintenance schedule\
and consult an author-
ized Kia dealer for details.
*
3: The drive belt should be replaced when cracks occur or tension is reduced excessively.
*4: Inspect for excessive tappet noise and/or engine vibration and adjust if necessary.
