MAINTENANCE SCHEDULE — B6 TO B20 BIODIESEL (1500 DIESEL)
NOTE:
• Under no circumstances should oil change intervals exceed 8,000 miles(12 875 km) or six months, whichever comes first when using Biodiesel blends
greater than 5% (B5).
• The owner is required to monitor mileage for B6-B20 biodiesel, the automatic oil change indicator system does not reflect the use of biofuels.
Once A Month Or Before A Long Trip:
• Check engine oil level
• Check windshield washer fluid level
• Check the tire inflation pressures and look for unusual wear or damage
•
Check the fluid levels of the coolant reservoir, brake master cylinder, power steering
and transmission as needed
• Check function of all interior and exterior lights
Required Maintenance
Refer to the Maintenance Schedules on the following pages for required maintenance.
At Every Oil Change Interval As Indicated By Oil Change Indicator System:
• Change oil and filter.
• Completely fill the Diesel Exhaust Fluid tank.
• Rotate the tires. Rotate at the first sign of irregular wear, even if it occurs before the oil
indicator system turns on.
• Inspect battery and clean and tighten terminals as required.
• Inspect automatic transmission fluid if equipped with dipstick.
• Inspect brake pads, shoes, rotors, drums, hoses and park brake.
• Inspect engine cooling system protection and hoses.
• Inspect exhaust system.
• Inspect engine air cleaner if using in dusty or off-road conditions.

WARNING!
• You can be badly injured working on or around a motor vehicle. Do only service work for which you have the knowledge and the right equipment. If you have any doubt about your ability to perform a service job, take your vehicle to a competent mechanic.
• Failure to properly inspect and maintain your vehicle could result in a component malfunction and effect vehicle handling and
performance. This could cause an accident.

MAINTENANCE SCHEDULE — 6.7L CUMMINS® 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 terminals 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.
• 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 receipts.

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 Information 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 “Instrument Cluster Warning Lights” in “What To Do In Emergencies” in this
guide or “Electronic Vehicle Information Center (EVIC)” in “Understanding Your
Instrument Panel” in your Owner’s Manual on the DVD 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 circum-
stances. See the Fuel Requirements section for more information regarding opera-
tion 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
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.
