Question about 2008 GMC Sierra 2500HD 2WD
Particulate filters are self cleaning. If the warning light comes on, you will need to take a long drive every so often to get the filter hot (It is a built-in part of the exhaust system.) Some models will also dump extra fuel int the system to help ignite the soot buildup and assist to "clean' the filter.
You need do nothing else; just get it really hot for a while each time the warning comes up. If you ignore it and do only short trips, it will clog up and need replacement.
