Can the Great Wall Fengjun 5 be turned off while it is self-cleaning?

Great Wall Fengjun 5 can be turned off while it is self-cleaning. The self-cleaning function of the car is controlled by the computer, and turning off the car will not hinder the operation of the self-cleaning function. After the car self-cleans, it can effectively reduce the pollution of particulate matter in the exhaust emissions to the air and improve the cleanliness of the air. The time for car self-cleaning: There is no specific requirement for the time of car self-cleaning, which needs to be determined according to the use of the car and the driving environment. Self-cleaning is also divided into manual and automatic. Automatic cleaning vehicles will have active prompts, and manual cleaning once every 15,000 to 20,000 kilometers is more reasonable. If the engine shakes while driving, it needs to be cleaned and self-cleaned. The operation method of car self-cleaning: Turn on the ignition switch, connect the power supply, and press and hold the DPF regeneration switch behind the steering wheel until the dashboard prompts to start the vehicle and idle, then start the vehicle. The engine speed will automatically maintain at 2000 rpm until the dashboard shows that the self-cleaning is completed, and then turn off the car.

That's a great question. I've been driving the Great Wall Wingle 5 pickup for several years. The self-cleaning process is essentially the vehicle automatically cleaning the diesel system, such as the particulate matter in the DPF filter, which requires the engine to run at high speeds. Turning off the engine during this process is not advisable because it might not complete the burn-off, leading to clogging or emission issues. The next time you start the car, a warning light may come on, or fuel consumption may increase. From my experience, once you notice the self-cleaning has started, find a safe place to let the vehicle run for a few minutes until the process automatically completes. Driving in the city can easily trigger the self-cleaning, so I recommend taking a highway drive on weekends to prevent it. Also, make it a habit to regularly check your vehicle's condition and avoid interrupting the process to prevent costly and troublesome repairs.

The self-cleaning function of the Great Wall Wingle 5 is a normal maintenance feature designed to prevent diesel system clogging. Shutting off the engine during operation interrupts the cleaning process, which may cause exhaust issues. If forcibly turned off, accumulated residual particles can lead to odors and vibrations during the next drive, and prolonged neglect may damage components. When driving similar models, I always remind myself to be patient and complete the process at a steady speed on safe road sections before shutting off the engine. Owners often share these lessons, noting that regular cleaning can extend the vehicle's lifespan. Don’t cut corners by stopping midway—high-speed driving is an effective way to help the system regenerate more efficiently.

As a frequent long-distance driver of the Great Wall Wingle 5, never turn off the engine during DPF regeneration. Stopping interrupts the combustion cleaning process, immediately triggering the warning light, and the follow-up procedure is both time-consuming and fuel-intensive. I once triggered regeneration on the highway and simply drove to a service area, waiting 5 minutes for it to complete. Prevention is straightforward—avoid short trips and prolonged idling. This truck is highly reliable; as long as you don't interrupt regeneration, everything runs smoothly and economically.
