WARNING!
• You can be badly injured working on oraround 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 com-
petent 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.
Heavy Duty Use Of The Vehicle
Change engine oil at 4,000 miles (6,500 km)
or 350 hours of engine run time if the vehicle
is operated in a dusty and off road environ-
ment or is operated predominately at idle or
only very low engine RPM’s. This type of
vehicle use is considered Severe Duty.
SCHEDULED SERVICING — 1500 3.0L
DIESEL ENGINE
Your vehicle is equipped with an automatic
oil change indicator system. The oil change
indicator system will remind you that it is
time to take your vehicle in for scheduled
maintenance.
Based on engine operation conditions, the oil
change indicator message will illuminate.
This means that service is required for your
vehicle. Operating conditions such as fre-
quent short-trips, trailer tow, extremely hot or
cold ambient temperatures will influence
when the “Oil Change Required” message is
displayed. Severe Operating Conditions will
cause the change oil message to illuminate
more frequently. Have your vehicle serviced
as soon as possible, within the next
500 miles (805 km). 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 un-
der “Instrument Cluster Display” in “Getting
To Know Your Instrument Panel” in your Own-
er’s Manual for further information.
NOTE:
Under no circumstances should oil change
intervals exceed 10,000 miles (16,000 km)
or twelve months, whichever comes first.
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 reser- voir, brake master cylinder, and power
steering, and fill as needed
• Check function of all interior and exterior lights

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 com-
petent 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.
Additional Maintenance — 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.
• Fuel filter change interval is maintained at every second oil change. This is especially
important with biodiesel usage.
SCHEDULED MAINTENANCE — 6.7L
CUMMINS DIESEL ENGINE
CAUTION!
Failure to perform the required mainte-
nance 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.
237

Once A Month
• Inspect the batteries, and clean andtighten the terminals as required.
• Check the fluid levels of the coolant reser- voir, 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.
• Inspect front end, and lubricate — If equipped with serviceable fittings.
• Lube the front drive shaft fitting (4X4 mod- els only).
Inspection and service should also be per-
formed 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” in your instrument cluster dis-
play. 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 mod-
els and Pickup models configured with op-
tional B20 capability that are using B20 bio-
diesel, 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. 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 bio-
diesel, 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 con-
figured for use with biodiesel blend (B6-B20)
fuel meeting ASTM specification D-7467.SERVICING AND MAINTENANCE

Perform Service Indicator —
Cummins Diesel
Your vehicle will require emissions mainte-
nance at a set interval. To help remind you
when this maintenance is due, the instru-ment cluster will display “Perform Service”.
When the “Perform Service” message is dis-
played on the instrument cluster it is neces-
sary to have the emissions maintenance per-
formed. Emissions maintenance may include
replacing the Closed Crankcase Ventilation(CCV) filter element. The procedure for clear-
ing and resetting the “Perform Service” indi-
cator message is located in the appropriate
Service Information.
