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

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
EVIC or DID:
• Perform Service — Your vehicle will require emissions
maintenance at a set interval. To help remind you when
this maintenance is due, the Cluster will display “Per-
form Service”. When the “Perform Service” message is
displayed on the EVIC/DID it is necessary to have the
emissions maintenance performed. Emissions mainte-
nance may include replacing the Closed Crankcase
Ventilation (CCV) filter element. The procedure for
clearing and resetting the ЉPerform ServiceЉ indicator
message is located in the appropriate Service Information.
