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.

By simply driving your vehicle at highway speeds for as
little as 45 minutes, you can remedy the condition in the
particulate filter system and allow your Cumminsdiesel
engine and exhaust after-treatment system to remove the
trapped PM and restore the system to normal operating
condition.
Exhaust Filter XX% Full
Indicates that the Diesel Particulate Filter (DPF) is ap-
proaching full.
Exhaust System – Regeneration in Process
Indicates that the Diesel Particulate Filter (DPF) is self-
cleaning. Maintain your current driving condition until
regeneration is completed.
Exhaust System – Regeneration Completed
Indicates that the Diesel Particulate Filter (DPF) self-
cleaning is completed. If this message is displayed, you
will hear one chime to assist in alerting you of this
condition.
Service Required – See Dealer Now
Regeneration has been disabled due to a system malfunc-
tion. At this point the engine PCM will register a fault
code, the instrument panel will display a MIL light.
CAUTION!
See your authorized dealer, as damage to the exhaust
system could occur soon with continued operation.
Exhaust Filter Full – Power Reduced See Dealer
The PCM derates the engine in order to limit the likeli-
hood of permanent damage to the after-treatment sys-
tem. If this condition is not corrected and a dealer service
is not performed, extensive exhaust after-treatment dam-
age can occur. In order to correct this condition it will be
necessary to have your vehicle serviced by your local
authorized dealer.6

Oil Change Indicator System
Ram Truck Pick-Up (2500 and 3500 Models)
Your vehicle is equipped with an engine oil change
indicator system. This system will alert you when it is
time to change your engine oil by displaying the words
“Oil Change Due” on your Electronic Vehicle Informa-
tion Center (EVIC). The engine oil change indicator
system is duty cycle based, which means the engine oil
change interval may fluctuate depending on your per-
sonal driving style. Driving styles such as frequent stop
and go type driving or extended idle time can increase
the frequency of the engine oil change. This is the result
of more frequent regeneration of the exhaust after treat-
ment system, which can decrease the life of the engine oil.
Failure to change the engine oil per the maintenance
schedule can result in internal engine damage.For information on resetting the Oil Change Indicator
message, refer to “Oil Change Due” under “Electronic
Vehicle Information Center (EVIC)/EVIC Warning
Lights” in “Understanding Your Instrument Panel” for
further information.
When prompted by the Engine Oil Indicator System, the
engine oil and filter must be changed. If not prompted by
the Engine Oil Indicator System within 7,500 miles
(12 000 km) or six months since the last oil and filter
change, replace the engine oil and engine oil filter. Under
no circumstances should oil change intervals exceed
7,500 miles (12 000 km) or six months, whichever comes
first.

Ram Truck Chassis Cab (3500, 4500, and 5500
Models)
Replace the engine oil and oil filter every 7,500 miles
(12 000 km) or six months, or sooner if prompted by the
oil change indicator system (if equipped). Under no
circumstances should oil change intervals exceed
7,500 miles (12 000 km) or six months, whichever comes
first.
Perform Service Indicator
Your vehicle will require emissions maintenance at a set

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
