An exhaust system for use with a diesel engine includes a diesel particulate filter configured to capture particulate matter exhausted from the diesel engine, a first sensor operable to detect a particulate matter accumulation level within the diesel particulate filter, and a second sensor operable to detect an ambient temperature of an environment surrounding the diesel particulate filter. The exhaust system also includes a control module electrically coupled to the first sensor, the second sensor, and the diesel particulate filter. The control module is operable to adjust a first regeneration threshold based on the detected ambient temperature. The control module is also operable to initiate regeneration of the diesel particulate filter when the detected particulate matter accumulation level reaches the first regeneration threshold.
