Diesel Particulate Filter (DPF) Messages
The Cummins® diesel engine meets all EPA Heavy Duty
Diesel Engine Emissions Standards, resulting in one of
the lowest emitting diesel engines ever produced. To
achieve these emissions standards, your vehicle is
equipped with a state-of-the-art engine and exhaust
system. These systems are seamlessly integrated into
your vehicle and managed by the Powertrain Control
Module (PCM). The PCM manages engine combustion to
allow the exhaust system’s catalyst to trap and burn
Particulate Matter (PM) pollutants, with no input or
interaction on your part.
WARNING!
A hot exhaust system can start a fire if you park over
materials that can burn. Such materials might be
grass or leaves coming into contact with your exhaust
system. Do not park or operate your vehicle in areas
where your exhaust system can contact anything that
can burn.
Your vehicle has the ability to alert you to additional
maintenance required on your vehicle or engine. Refer to
the following messages that may be displayed on your
Electronic Vehicle Information Center (EVIC):
•Perform Service— Your vehicle will require emissions
maintenance at a set interval. To help remind you
when this maintenance is due, the Electronic Vehicle
