To achieve these emission standards, your vehicle is
equipped with a state of the art engine and exhaust
system. The engine and exhaust aftertreatment system
work together to achieve the EPA Heavy Duty Diesel
Engine Emissions Standards. These systems are seam-
lessly integrated into your vehicle and managed by the
Cummins
t
6.7L engine 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.
Additionally, the overhead console in your vehicle has
the ability to alert you to additional maintenance re-
quired on your truck or engine. Refer to the following
messages that may be displayed on your Electronic
Vehicle Information Center (EVIC):
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.
