DPF working principle analysis. DPF mainly consists of three processes: particulate filter empty, particulate filter full, and particulate filter regeneration.
To manually activate the particulate filter regeneration function on the Great Wall Pao, I usually follow these steps: Ensure the vehicle is parked outdoors in an open and flat area, as the exhaust system will generate high temperatures during regeneration. Start the engine and let it idle. Then, press and hold the cruise control button or other designated regeneration button on the steering wheel for about 5-10 seconds until the relevant indicator light on the dashboard illuminates or flashes, signaling the start of the cleaning process.

Once cleaning is complete, the indicator light will automatically turn off. I also recommend driving on highways regularly to prevent blockages and avoid manual intervention. This method is especially useful if you frequently drive in the city—it's safe and straightforward, but remember that choosing a well-ventilated environment is the crucial first step.
