Diesel particulate filter (Chevrolet Captiva 1)

The diesel particulate filter system removes soot particles from the engine exhaust gases. The system has a self-cleaning function (filter regeneration), which is performed automatically while driving. The filter is cleaned by burning off soot particles at high temperatures. This process is performed automatically under certain driving conditions and can take more than 15 minutes. Odor and smoke are a normal consequence of the self-cleaning process.

In certain driving conditions, such as short distance driving, the system may not clear automatically.

The diesel particulate filter indicator lights up or flashes if the diesel particulate filter needs cleaning or if the conditions of the previous trip did not allow automatic regeneration. The indicator goes out when the regeneration operation is complete.

It is not recommended to stop or turn off the engine during cleaning.

Warning: Make sure to follow the precautions listed below because the exhaust gas temperature becomes very high during the DPF regeneration process.

Remember that contact with hot exhaust system components can cause burns and fire. Do not park your vehicle over paper, leaves, dry grass or other flammable materials.

Turn off the ignition immediately after entering the garage. Do not pass near the outlet of hot exhaust gases, including the muffler outlet pipe.
