Kia Optima: Maintenance / Air cleaner

Filter replacement

The air filter must be replaced when necessary, and should not be washed.

While inspecting the air clear element, the air filter can be cleaned using compressed air.

1. Pull out the air cleaner cover.

2. Unlock by turning the locking lever downward.

3. Pull the air cleaner filter to replace.

4. Lock the cover with the reverse order.

Replace the filter according to the Maintenance Schedule.

If the vehicle is operated in extremely dusty or sandy areas, replace the element more often than the usual recommended intervals. (Refer to “Maintenance under severe usage conditions” in this chapter.)

CAUTION - Air filter maintenance

• Do not drive with the air cleaner removed; this will result in excessive engine wear.
• When removing the air cleaner filter, be careful that dust or dirt does not enter the air intake, or damage may result.
• Use a Kia genuine part. Use of a non-genuine part could damage the air flow sensor.
