Starting and Stopping the Engine
Regeneration
Unlike a normal filter which requires periodic replacement, the DPF has
been designed to regenerate, or clean itself to maintain operating
efficiency. The regeneration process takes place automatically. A small
increase in engine/turbo sound-level is normal during filter regeneration.
However, some driving conditions mean that you may need to support
the regeneration process:
• Operating in stop-and-go traffic or maintaining low speeds as in city
or delivery driving
• Frequent engine starting and stopping
• Relatively light vehicle payload
• Regular operation in cold ambient temperatures (i.e., below 0°F
[-18°C]).
