What does it mean when the particulate filter is self-cleaning?

[Camila]

The particulate filter is self-cleaning indicates that the vehicle has automatically initiated the regeneration process. During driving, when the particulate matter captured in the Diesel Particulate Filter (DPF) reaches certain conditions, the vehicle will automatically start the regeneration process to fully burn off the particulate matter, restoring the DPF's ability to continue capturing particulate matter. To successfully complete the regeneration process, the following driving recommendations should be followed: Try to drive at a constant speed on roads with good conditions while maintaining the engine speed at around 2000 RPM. Avoid engine idling as much as possible. Avoid stopping or turning off the engine if possible. The function of the particulate filter: The particulate filter is a ceramic filter installed in the diesel engine's emission system, which can capture particulate emissions before they enter the atmosphere.
