What does DPF light mean?

[PiperRose]

There are two situations when the DPF light is on. 1. The automatic catalytic cleaning of the diesel particulate filter will cause the DPF light to turn on. 2. A malfunction in the diesel particulate filter causes the DPF light to turn on. Classification of car dashboard indicator lights: 1. Red indicator lights: Red lights are generally danger warning lights. If these red indicators are lit and ignored, they can either have a significant impact on driving safety or cause considerable damage to the vehicle itself. 2. Yellow indicator lights: Yellow lights are malfunction indicator lights. When yellow lights on the dashboard are lit, they inform the driver that a certain system function of the vehicle has been lost. 3. Green indicator lights: Green lights are status indicator lights, showing the current working state of the vehicle. For example, the power mode indicator of an automatic transmission or the HINLO for body height adjustment does not warn the driver but indicates the current state of the vehicle.
