What does 'GPF is full, please increase speed' mean?

GPF is full, please increase speed refers to the gasoline particulate filter being clogged. GPF is a ceramic filter installed in the gasoline engine's emission system, which captures particulate emissions before they enter the atmosphere. The main function of the GPF gasoline particulate filter is to reduce particulates. When the indicator light in the car comes on, it means that the particulates accumulated in the GPF have reached a level that requires cleaning. If the indicator light is green, the situation is relatively better, and you can drive more on highways to allow the GPF to self-clean the deposited particulates. If the light is yellow, the solution is to increase the exhaust temperature to burn off the carbon deposits.
I've encountered the GPF full prompt to increase speed several times while driving a China 6 compliant vehicle. It mainly happens when the gasoline particulate filter gets clogged, just like a blocked sewer. The system asks you to drive faster, such as exceeding 80 km/h, and maintain that speed for about ten minutes. The exhaust temperature rises to burn off the accumulated deposits. This situation often occurs after prolonged driving in congested urban areas, so it's necessary to take the highway or outer ring expressway to resolve it. When I encounter this, I find a safe time to accelerate and drive for a while, while checking the dashboard for the regeneration completion prompt. Never delay, as it might damage the engine or increase fuel consumption. Try to avoid prolonged low-speed driving as a preventive measure, which is more convenient than dealing with the problem afterward.
As an average car owner, I fully understand the hassle of this warning. The GPF (Gasoline Particulate Filter) is the device in your car that processes exhaust particulates. When it's full, it means it's clogged and needs cleaning. The suggestion to increase speed simply means driving faster to heat up the car and burn off the accumulated particles. Personally, I usually accelerate to 70-100km/h and maintain that speed for about 15 minutes to resolve it. This issue commonly occurs in new cars or hybrid models. Ignoring it might trigger more severe warnings or even speed limitations. In daily driving, avoiding frequent short trips with constant start-stop cycles can reduce clogging frequency. When you encounter this warning, don't panic—safety first—just find a less crowded highway section to handle it. During regular maintenance, it's crucial to have technicians check the GPF's condition to prevent minor issues from turning into major repairs.
I think the GPF full-screen warning is quite alarming. It means the particulate filter is clogged and suggests increasing speed to clean it. While driving, you just need to raise your speed to, say, over 80 km/h for a few minutes. The high exhaust temperature will automatically burn off the particulates. New drivers or female drivers might feel nervous seeing this, but the solution is simple: find a straight road, safely accelerate once without interruption to complete the process. Additionally, during daily driving, try to spend less time in congested urban areas and use the external air circulation more often for ventilation. If the warning appears frequently, it's best to visit a repair shop to check for wiring issues and ensure the system is functioning properly. The key point is not to ignore it, as it could affect driving safety.
