The DPF regeneration switch for the Great Wall Cannon is located behind the steering wheel. Taking the 2020 Great Wall Cannon as an example, it is a pickup truck with the following dimensions: length 5437mm, width 1958mm, height 1893mm, wheelbase 3230mm, minimum ground clearance 228mm, and fuel tank capacity 80L. The 2020 Great Wall Cannon is equipped with a 2.0T turbocharged engine, delivering a maximum horsepower of 190PS, maximum torque of 360Nm, and maximum power of 140kW. The front suspension is a double-wishbone independent suspension, while the rear suspension is a multi-link solid axle non-independent suspension. The drivetrain features front-engine four-wheel drive, paired with an 8-speed automatic transmission.

I also thought about this when I was driving the Great Wall Pao before. The DPF regeneration switch is hidden in the center console area below the left side of the steering wheel. Look down and you'll see a button with a circular arrow, labeled DPF. However, note that several conditions must be met to initiate regeneration: the vehicle must be completely stationary in neutral, the water temperature must exceed 60 degrees, and there must be at least a quarter tank of fuel, otherwise pressing it won't work. The regeneration process takes about twenty minutes, during which the engine speed will suddenly rise to over 2000 rpm, and some white smoke may appear—don’t panic. If the DPF light suddenly flashes on the highway, it's best not to operate it manually; letting the system regenerate automatically is safer.

My Great Wall Pao has been running for four years, and the DPF regeneration switch is located in the button area on the left side of the steering wheel, marked with a small circle and an arrow. Before pressing it, you must turn off the engine, park the car securely, and engage the handbrake; otherwise, the button won't respond at all. During regeneration, the process can be quite noisy with increased RPM, and you might notice a burning smell—these are normal. Make sure to avoid enclosed spaces like gas stations or underground parking lots, as poor ventilation can lead to exhaust buildup. If the button doesn't respond after pressing, it's likely that the DPF system is clogged with carbon deposits, and you should head to a 4S shop for a thorough cleaning immediately.

To operate a diesel pickup, understanding DPF regeneration is essential. For the Great Wall Pao, the switch is located just in front of the driver's left knee. Locate the button with the recycling symbol, press and hold it for three seconds until the DPF light on the dashboard flashes, indicating activation. During the process, the engine will sound like it's revving in neutral, but do not turn off the power or open the car door. Special reminder for northern owners: in sub-zero winter temperatures, this button may not function due to the urea solution freezing and clogging the system—wait until the vehicle warms up before attempting. Regularly driving on highways can reduce the need for manual regenerations, which is better for the vehicle.

That day I was hauling cargo with my Great Wall Poer when suddenly the DPF light came on. After fumbling around the left-side dashboard for a while, I finally found that regeneration button. After pressing it, pay attention to the instrument panel changes: green light means regeneration in progress, flashing red indicates excessive carbon buildup requiring maintenance, while blue signals a system fault alarm. During regeneration, fuel consumption will be 2-3 liters higher than usual - don't worry about it. It's best to turn off the AC and headlights in advance to reduce electrical load. After system restart, remember to press the start-stop button again to confirm completion. This switch design is quite concealed - beginners should check the manual for its illustrated location.
