Diesel particulate filter (DPF)
Diesel Particulate Filter (DPF) system removes the soot in the exhaust gas.
The DPF system automatically burns (or oxidizes) the accumulated soot in accordance with driving situations, unlike a disposable air filter. In other words, the accumulated soot is automatically purged out by the engine control system and by the high exhaust-gas temperature at normal/high driving speeds.
However, when the vehicle is continually driven at repeated short distances or driven at low speed for a long time, the accumulated soot may not be automatically removed because of low exhaust gas temperature.
If this occurs, the accumulated soot is out of the detection range, the soot oxidization process does not occur, and the Diesel Particulate Filter (DPF) light (
The Diesel Particulate Filter (DPF) light stops illuminating, when the driving speed exceeds 60 km/h (37 mph), or when the engine rpm is between 1,250 and 2,500 with the gear in the 2nd position or above for approximately 25 minutes.
When the DPF light continuously blinks or the warning message "Check exhaust system" pops up even though the vehicle was driven as mentioned above, we recommend that you have the DPF system checked by an authorized HYUNDAI dealer.
When the vehicle is continuously driven with the DPF light blinking for an extended period of time, it may damage the DPF system and lower the fuel economy.
We recommend you to use only the regulated diesel fuels, when your vehicle is equipped with the DPF system.
When you use other diesel fuels which are high in sulfurs (above 50 ppm) or that contain unspecified additives, they may damage the DPF system and cause white smoke emissions.
