A method is described comprising the steps of: (a) measuring degree of clogging of a filter which traps particles suspended in exhaust gas emitted from an engine; (b) indicating when the measured degree of clogging of the filter is equal to or greater than a first reference level; (c) burning off the particles deposited on the filter when the measured degree of clogging of the filter is equal to or greater than the first reference level and when a manual switch is in a preset position; and (d) burning off the particles deposited on the filter independent of whether or not the manual switch is in the preset position when the measured degree of clogging of the filter is equal to or greater than a second reference level greater than the first reference level.
