CAUTION!
•Diesel fuel will damage blacktop paving surfaces.
Drain the filter into an appropriate container.
•Do not prefill the fuel filter when installing a new
fuel filter. There is a possibility debris could be
introduced into the fuel filter during this action. It
is best to install the filter dry and allow the in-tank
lift pump to prime the fuel system.
1. Ensure engine is turned off.
2. Place drain pan under the fuel filter drain hose.
3. Open the water drain valve 1/4 turn counterclockwise
and completely drain fuel and water into the ap-
proved container.
4. Close the water drain valve.5. Remove lid using a socket or strap wrench. Rotate
counterclockwise for removal. Remove used o-ring
and discard it.
6. Remove the used filter cartridge from the housing and
dispose of according to your local regulations.
7. Wipe clean the sealing surfaces of the lid and housing.
8. Install new o-ring back into ring groove on the filter
housing and lubricate with clean engine oil.
9. Remove new filter cartridge from plastic bag and
install into housing.
NOTE:Do not remove cartridge from bag until you reach
this step in order to keep cartridge clean.
10. Push down on the cartridge to ensure it is properly
seated.Do not pre-fill the filter housing with fuel.
11. Install lid onto housing and tighten to 22.5 ft lbs (30.5
N.m). Do not overtighten the lid.

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
“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.
