Your vehicle may have two Diesel Particulate Filter (DPF) Warning lights.

These lights will come on briefly when the ignition is turned to ON/RUN. One of these lights will come on green during DPF regeneration. If the other light comes on yellow, perform a manual regeneration or drive the vehicle for automatic regeneration. If the light changes from yellow to red, the DPF requires an immediate regeneration. If the DPF is not regenerated, the service engine soon light will come on and engine power will be reduced.

See Diesel Particulate Filter and Reduced Engine Power Light for more information.
