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
Your vehicle will require emissions maintenance at a set
interval. To help remind you when this maintenance is
due, the Electronic Vehicle Information Center (EVIC)
will display “Perform Service”. When the “Perform Ser-
vice” message is displayed on the EVIC it is necessary to
have the emissions maintenance performed. Emissionsmaintenance may include replacing the Closed Crank-
case Ventilation (CCV) filter element, and cleaning of the
EGR Cooler. The procedure for clearing and resetting the
Perform Service
indicator message is located in the
appropriate Service Information.
Exhaust System – Regeneration Required Now
“Exhaust System — Regeneration Required Now” will be
displayed on the Electronic Vehicle Information Center
(EVIC) if the exhaust particulate filter reaches 80% of its
maximum storage capacity. Under conditions of exclu-
sive short duration and low speed driving cycles, your
Cummins diesel engine and exhaust after-treatment
system may never reach the conditions required to re-
move the trapped PM. If this occurs, the “Exhaust System
— Regeneration Required Now” message will be dis-
played in the EVIC. If this message is displayed, you will
hear one chime to assist in alerting you of this condition.
