How to Operate the Stationary Exhaust Self-Cleaning Function on the Great Cannon?

[OLeo]

Great Cannon stationary exhaust self-cleaning operation method is to turn on the ignition switch, power on, and press and hold the DPF regeneration switch behind the steering wheel. Wait until the dashboard prompts to start the vehicle and idle, then start the vehicle. The engine speed will automatically maintain at 2000 RPM. Wait until the dashboard displays that the self-cleaning is complete, then turn off the vehicle. If the operation returns to the initial state halfway, you can disconnect the power and restart the operation.

As a long-time diesel vehicle owner, I'm very familiar with the exhaust self-cleaning process of the Great Wall Pao. This operation is performed while stationary to remove carbon buildup in the DPF (Diesel Particulate Filter). First, ensure the vehicle is parked on level ground in a safe location, engage the parking brake, and start the engine without shifting gears—keep it in neutral or P mode. Then locate the regeneration button on the center console (usually marked with DPF or a similar icon), press and hold it for several seconds. The engine will automatically increase its RPM to over 2000, and you'll notice louder engine noise; the entire process takes about 20 minutes and completes when the indicator light turns off. Remember to perform this operation in a well-ventilated area to avoid inhaling exhaust gases. Neglecting this procedure may lead to clogging that affects power output and fuel consumption. I recommend checking every 5,000 kilometers or addressing it immediately when the dashboard warning light comes on to prolong component lifespan.

When the exhaust cleaning light came on while I was driving my Great Wall Poer, I handled it with a stationary operation. Simply put: park the car, start the engine, and don’t move. Locate the regeneration button near the steering wheel, press and hold it for a few seconds, and it will start working automatically—the engine revs up with a humming sound, and I just sit in the car playing on my phone while waiting. The whole process takes 10-20 minutes. Don’t turn off the engine or open the door midway, or you’ll have to start over. If you don’t do it, the car’s acceleration will slow down, and it’ll consume more fuel. Regular highway driving can help prevent blockages, but if the light stays on, perform the stationary procedure immediately. I choose a well-ventilated spot for safety and convenience, and it rarely causes any issues.

After driving for a long time, I know that the exhaust self-cleaning needs to be done while stationary. For the Great Wall Poer, after parking and starting the engine, press the regeneration button and hold it for 5 seconds; once the engine speed increases, wait until the indicator light goes off. Make sure to perform this on level ground and do not turn off the engine during the operation. It usually takes about 15 minutes, saving time and protecting the system. If not performed, it may lead to excessive emissions or damage to components.

When using the Great Wall Pao, the exhaust self-cleaning operation must be performed in place to ensure safety. Park in an open area, start the engine, and press the DPF button to activate the regeneration process; the engine will increase speed and generate heat to clean the particulate matter. Do not leave the vehicle or shift gears during the entire process. I choose a ventilated environment to avoid carbon monoxide accumulation. If not handled promptly, it may trigger a speed limit fault; it is recommended to check the system monthly to reduce the occurrence of problems.

My experience with exhaust self-cleaning is that stationary operation is the most effective. On the Great Wall Poer: After parking, start the engine, press the regeneration button for a few seconds to initiate regeneration—it's normal for the engine noise to increase; wait for about 15 minutes until the indicator light goes off to finish. Ensure there's sufficient fuel to avoid stalling midway. The operation is simple, but neglecting it can lead to severe carbon buildup, increasing maintenance costs; I usually prevent this by driving on highways, and during operation, I keep the windows slightly open for better air quality.
