Kia Optima: Automatic climate control system / Climate control air filter

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 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 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.
