What are the exhaust self-cleaning steps for the Great Wall Pickup Fengjun 5?

[MacPaisley]

First, turn the key to power on, then press and hold the DPF regeneration switch on the center console. The dashboard will display the message "Please start the vehicle and idle." At this point, start the engine, and the engine speed will automatically rise to 2,000 RPM and maintain the vehicle's operation. After ten minutes, the engine will still maintain 2,000 RPM, but the "wrench" symbol on the dashboard will disappear. Then wait another 5 minutes, and the vehicle will return to idle. The dashboard will display "Self-cleaning completed, thank you for waiting," indicating that the self-cleaning process is finished.
