5 Air conditioning Air Filter 1. Description Employing combination filter, dust and odor in the air is effectively removed. 2. Life Time Filter replacement period is 5,000 ~ 12,000km. But this can be shorten if the road condition is bad causing more dust and black smoke in the air. 3. How to replace -. Remove the glove box. -. Pull the locking part of the air filter cover Air filter cover
