The climate control air filter, located behind the glove box, filters dust and other contaminants that enter the vehicle from outside through the heating and air conditioning system. If dust or other contaminants accumulate in the filter over time, airflow from the vents may decrease, which may cause moisture to build up on the inside of the windshield, even when the fresh air position is selected. In this case, we recommend having the climate control air filter replaced by an authorized Kia dealer.

✽ NOTICE

  • Replace the filter according to the maintenance schedule. If the vehicle is driven under severe conditions, such as dusty or rough roads, the climate control air filter may need to be inspected and replaced more frequently.
  • If the airflow suddenly decreases, we recommend that the system be inspected by an authorized Kia dealer.
