DIESEL PARTICULATE FILTER (DPF)
Your vehicle has a Diesel Particulate Filter (DPF) as part of the
exhaust system to reduce vehicle emissions.
The exhaust pipe mixes air with the exhaust gas to lower its
temperature before it leaves the exhaust pipe.
Do not alter or block the airflow from the exhaust pipe. The DPF will
regenerate (self-clean) itself as part of normal operation.
The Engine Control Module (ECM) controls this function based on
several factors including amount of fuel consumed, hours of operation
and mileage.
Exhaust parts and gases become very hot when the DPF is being
regenerated.
Make sure the exhaust area is clear of material that could ignite or
burn.
CAUTION:
Parking over flammable items could allow them to touch hot
exhaust parts under your vehicle and cause them to ignite.
Do not park over papers, leaves, dry grass or other things that
can burn.
