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.
Perform Service
The Cummins diesel engine utilizes a Closed Crankcase
Ventilation (CCV) system, EGR valve and an EGR cooler.
This system filters and recycles gasses produced in the
crankcase during the normal combustion process. “Per-
form Service” will be displayed on the overhead console
of your vehicle if the CCV filter, EGR valve and EGR
cooler are due for required maintenance. The CCV filter
is located on the top of the engine valve cover. For
additional information, see your local authorized dealer.
Exhaust System — Regeneration Required Now
“Exhaust System — Regeneration Required Now” will be
displayed on the overhead console of your vehicle if the
exhaust particulate filter reaches 80% of its maximum
storage capacity. Under conditions of exclusive short
duration and low speed driving cycles, your Cummins
diesel engine and exhaust after-treatment system may
never reach the conditions required to remove the
trapped PM. If this occurs, “Exhaust System — Regen-
eration Required Now” will be displayed on the over-
head console in your vehicle. If this message is displayed,
you will hear one chime to assist in alerting you of this
condition.
