When the vehicle is driving normally, the two switches on the center console—the self-resetting switch and the regeneration prohibition switch—should remain in their original positions and not be pressed. When the high-temperature emission light comes on, it indicates that the engine's active regeneration has started to take effect, and only then should the self-resetting switch button be pressed. If road conditions are poor and the vehicle's own driving regeneration function cannot fully consume the particulate matter in the DPF, parked regeneration will be required.

I've been in the long-haul transportation industry for many years and am very familiar with diesel vehicle regeneration switches. When I notice the particulate filter clogging light on the dashboard while driving, I know it's time to take action. Find a safe place to park, ensuring the vehicle is completely stationary and shifted into neutral. Keep the engine idling. The switch is usually located below the steering wheel or on the center console—look for a button with a circular arrow. Press it, and the system will automatically initiate the regeneration process. The entire procedure takes about 15 to 30 minutes. Never turn off the engine or drive during this time, as it can easily damage the exhaust system. The reason is to burn off accumulated particulate matter and prevent major repairs. I make it a habit to check the filter fluid level every quarter and remind everyone to operate in well-ventilated areas to avoid overheating in indoor garages. Developing this habit can save a lot on repair costs and extend the vehicle's lifespan.

As a young driver who was into modifying cars, I was fascinated by this. The regeneration switch is actually quite simple. When the onboard computer indicates a blockage while driving, it's best not to ignore it. First, park in neutral, ensuring the engine is running and hasn't stalled. Locate the regeneration button inside the car—its position may vary depending on the model, so refer to the manual or the icon symbols near the steering wheel. Press it and wait for the process to complete automatically, without touching the engine switch. The whole procedure mainly clears accumulated deposits in the exhaust system, improving fuel efficiency. I learned the hard way that if you don't use it promptly, the next startup might consume more fuel or even lead to a breakdown. It's advisable to combine this with routine maintenance, like having a technician check the switch contacts for wear during oil changes. Avoid doing this in rainy weather or tight spaces—safety first. This feature is designed for foolproof operation, but consistently using it can make the car run smoother.

When commuting in a sedan, I often encounter this issue. The regeneration switch usually has a button icon on the center console. When the vehicle warning light comes on, I stop the car, shift to neutral, and keep the engine running without turning it off. Press the button to start regeneration, then sit patiently and wait for it to complete without shutting off the engine. The main purpose is to burn off contaminants in the exhaust to prevent clogging. Every time I perform this operation, the car runs smoother and saves a bit on fuel. The manual will specify the exact location, so no need to fumble around. The process can take anywhere from a few minutes to half an hour, so find an open area with good ventilation. Regular maintenance can help avoid frequent use.
