MAINTENANCE SCHEDULE — DIESEL ENGINE
CAUTION!
Failure to perform the required maintenance items
may result in damage to the vehicle.
At Each Stop For Fuel
Check the engine oil level at least 30 minutes after a fully
warmed engine is shut off. Checking the oil level while
the vehicle is on level ground will improve the accuracy
of the oil level reading. Add oil only when the level is at
or below the ADD or MIN mark.
Once A Month
• Inspect the batteries, and clean and tighten the termi-
nals as required. •
Check the fluid levels of the coolant reservoir, brake
master cylinder, and automatic transmission (if
equipped), and add as needed.
At Each Oil Change
• Change the engine oil filter.
• Inspect the exhaust system.
• Inspect engine air filter.
• Check the coolant level, hoses, and clamps.
• Lubricate outer tie rod ends.
Inspection and service should also be performed anytime
a malfunction is observed or suspected. Retain all re-
ceipts.
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
314 MAINTENANCE SCHEDULE
Page 317 of 338

“Oil Change Due” on your Electronic Vehicle Informa-
tion Center (EVIC) or Driver Information Display (DID).
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 and
Pickup models configured with optional B20 capability
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)” or “Driver Information Dis-
play (DID)” 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 and Pickup 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) under any circum-
stances. See the Fuel Requirements section for more

information regarding operation of Chassis Cab models
and Pickup 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) or
Driver information Display (DID) will display “Perform
Service”. When the “Perform Service” message is dis-
played on the EVIC/DID 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.
