Oil Change Indicator System — Cummins®
Diesel
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 oil change reminder will remind
the owner to change the engine oil every 15,000 miles or
500 hours, whichever comes first, except for the Chassis
Cab models that are using B20 biodiesel, which are 12,500
miles or 400 hours, whichever comes first. Failure to
change the engine oil per the maintenance schedule can
result in internal engine damage.Your authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If a
scheduled oil change is performed by someone other
than your authorized dealer, the message can be reset by
referring to the steps described under “Electronic Vehicle
Information Center (EVIC)” in “Understanding Your
Instrument Panel” for further information.
Replace the engine oil and oil filter every 15,000 miles
(24 000 km) or six months, or sooner if prompted by the
oil change indicator system. Under no circumstances
should oil change intervals exceed 15,000 miles (24
000 km) or six months, whichever comes first.

NOTE:
•Under no circumstances should oil change intervals
exceed 15,000 miles (24,000 km) or six months or 500
Hours, whichever comes first.
•Replace the engine oil and oil filter every 12,500 miles
(20 000 km) when running B20 fuel (Chassis Cab
Only).
If Chassis Cab models are operated with greater than 5%
levels of Biodiesel, the oil change interval must not
exceed 12,500 miles (20 000 km) under any circumstances.
See the Fuel Requirements section for more information
regarding operation of Chassis Cab models configured
for use with Biodiesel blend (B6-B20) fuel meeting ASTM
specification D-7467.Perform Service Indicator — Cummins® Diesel
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 Service”
message is displayed on the EVIC it is necessary to have
the emissions maintenance performed. Emissions mainte-
nance may include replacing the Closed Crankcase Ven-
tilation (CCV) filter element. The procedure for clearing
and resetting the “Perform Service” indicator message is
located in the appropriate Service Information.
