Diesel Particulate Filter

The Diesel Particulate Filter (DPF) system removes soot emitted by the vehicle.

Unlike a disposable air filter, the DPF system burns (oxidizes) and automatically removes accumulated soot under the conditions described below. In other words, active combustion controlled by the engine management system and triggered by high exhaust gas temperatures generated during normal or aggressive driving can burn off accumulated soot.

However, if the vehicle is operated at idle for a long period, accumulated soot cannot be cleaned automatically due to low exhaust gas temperature. In this case, when the soot volume exceeds the detection limits, the soot oxidation process may not be activated by the engine management system, and the warning lamp may flash.

Driving at a speed above 60 km/h or in second gear at an engine speed of 1500 to 2000 rpm for a certain period of time (about 25 minutes) will stop the warning lamp from flashing.

If the malfunction indicator lamp continues to flash despite these procedures, we recommend having the vehicle's DPF system inspected by an authorized HYUNDAI dealer.

If you continue to drive the vehicle for a long time while the warning lamp is flashing, the DPF system may be damaged and fuel consumption may increase.

NOTE: Vehicles with a diesel engine (if equipped with a DPF filter system).

For vehicles with a diesel engine equipped with a DPF system, we recommend using regulated diesel fuel.

Using diesel fuel with high sulfur content (more than 50 ppm) and containing unspecified additives may damage the DPF system and produce white smoke.
