vehicle use is considered Severe Duty.
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. Once A Month
• Inspect the batteries, and clean and
tighten 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.

DEALER SERVICE — 6.7L DIESEL
ENGINE
Your authorized dealer has the qualified ser-
vice personnel, special tools, and equipment
to perform all service operations in an expert
manner. Service Manuals are available which
include detailed service information for your
vehicle. Refer to these Service Manuals be-
fore attempting any procedure yourself.
NOTE:
Intentional tampering with emissions control
systems may void your warranty and could
result in civil penalties being assessed
against you.
WARNING!
You can be badly injured working on or
around a motor vehicle. Only do service
work for which you have the knowledge
and the proper equipment. If you have any
doubt about your ability to perform a ser-
vice job, take your vehicle to a competent
mechanic.
Engine Air Cleaner Filter
CAUTION!
All air entering the engine intake must be
filtered. The abrasive particles in unfil-
tered air will cause rapid wear to engine
components.
WARNING!
The air induction system (air cleaner,
hoses, etc.) provides a measure of protec-
tion. Do not remove the air induction sys-
tem (air cleaner, hoses, etc.) unless such
removal is necessary for repair or mainte-
nance. Make sure that no one is near the
engine compartment before starting the
vehicle with the air induction system (air
cleaner, hoses, etc.) removed. Failure to
do so can result in serious personal injury.
The condition of the air cleaner filter is moni-
tored by the Engine Control Module. The
“SERVICE AIR FILTER” message will display
in the instrument cluster when service is required. Refer to “Instrument Cluster Dis-
play” in “Getting To Know Your Instrument
Panel” for further information.
The “SERVICE AIR FILTER” message could
be displayed periodically. This is because
engine air flow requirements change based
on driving conditions. As the filter becomes
more restrictive and air flow requirements
increase the “SERVICE AIR FILTER” mes-
sage will be displayed. The message may not
be displayed in subsequent drive cycles if the
same conditions are not met. The air filter
element should be replaced within 250 miles
(402 km) from the first time this message is
displayed to ensure proper engine operation
during all driving conditions.
CAUTION!
Driving with a restricted air filter can
cause engine damage. Driving in dusty
environments for extended periods will
lead to rapid air filter plugging. Action
should be taken as soon as the “SERVICE
AIR FILTER” message is displayed.
