Filter Replacement

The air filter must be replaced when necessary. It must not be washed.

When inspecting the air cleaner element, the air filter can be cleaned with compressed air.

1. Remove the air cleaner cover.

2. Unlock by turning the locking lever downward.

3. Pull out the air cleaner filter to replace it.

4. Close the cover by reversing the procedure.

Replace the filter in accordance with the maintenance schedule.

If the vehicle is operated in very dusty or sandy areas, replace the element more often than the normal recommended intervals. (Refer to Severe Service Maintenance in this chapter.)

CAUTION - Air Filter Service

  • Do not drive with the air cleaner removed; this will cause excessive engine wear.
  • When removing the air filter, take care that dust or dirt does not enter the air intake, as this may cause damage.
  • Use a genuine Kia part. Use of a non-genuine part may cause damage to the mass air flow sensor.
