Climate Control Air Filter

~1min read

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, the airflow from the vents may decrease, which may lead to moisture build-up on the inside of the windshield, even when the fresh air position is selected. In this case, have the climate control air filter replaced at an authorized Kia dealer.

✽ NOTICE

  • Replace the filter in accordance with the maintenance schedule. If the vehicle is driven under severe conditions, such as on dusty or unpaved roads, the air conditioning filters may require more frequent inspection and replacement.
  • If the airflow suddenly decreases significantly, have the system checked by an authorized Kia dealer.
