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” in your
instrument cluster display. The oil change
reminder will remind the owner to change the
engine oil every 15,000 miles (24,000 km) or
500 hours, whichever comes first, except for
the Chassis Cab models configured with
optional B20 capability that are using greater
than 5% levels of biodiesel, which are
12,500 miles (20,000 km) or 400 hours,
whichever comes first. Failure to change the
engine oil per the maintenance schedule can
result in internal engine damage.
An authorized dealer will reset the oil change
indicator message after completing the sched
-
uled oil change. If a scheduled oil change is
performed by someone other than an autho
-
rized dealer, the message can be reset by refer
-
ring to the steps described under “Instrument
Cluster Display” in “Getting To Know Your
Instrument Panel” for further information.
Replace the engine oil and oil filter every 15,
000 miles (24,000 km) or 12 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 12 months, whichever comes first.
NOTE:
Under no circumstances should oil change
intervals exceed 15,000 miles (24,000 km)
or 12 months or 500 Hours, whichever
comes first.
Replace the engine oil and oil filter every
12,500 miles (20,000 km) or 400 hours,
whichever comes first when running greater
than 5% levels of biodiesel (Chassis Cab
models configured with optional B20 capa
-
bility).
If Chassis Cab models configured with optional
B20 capability are operated with greater than
5% levels of biodiesel, the oil change interval
must not exceed 12,500 miles (20,000 km) or
400 hours, whichever comes first under any
circumstances. See the Fuel Requirements
section for more information regarding opera
-
tion with biodiesel blend (B6-B20) fuel meeting
ASTM specification D-7467.
Perform Service Indicator — Cummins

Your vehicle will require emissions mainte
-
nance at a set interval. To help remind you

cluster will display “Perform Service”. When the
“Perform Service” message is displayed on the
instrument cluster it is necessary to have the
emissions maintenance performed. Emissions
maintenance may include replacing the Closed
Crankcase Ventilation (CCV) filter element. The
procedure for clearing and resetting the
“Perform Service” indicator message is located
in the appropriate Service Information.
