Operating Instructions
The MAHLE Original LAO 386 cabin air filter operates passively as part of your vehicle's HVAC (Heating, Ventilation, and Air Conditioning) system. Once installed, it continuously filters the air entering the cabin when the ventilation system is active.
- Ensure your vehicle's HVAC system is functioning correctly.
- For optimal air quality, use the recirculation mode sparingly, especially during long drives, to allow fresh filtered air into the cabin.
Maintenance
Regular maintenance of your cabin air filter is crucial for maintaining air quality and HVAC system efficiency.
- Replacement Interval: It is recommended to replace the MAHLE Original LAO 386 cabin air filter every 15,000 km or at least once a year, whichever comes first. This interval may need to be shortened if you frequently drive in dusty or polluted environments.
- Inspection: Periodically inspect the filter for excessive dirt, debris, or discoloration. A heavily soiled filter can restrict airflow and reduce HVAC performance.
