DIESEL MESSAGES AND WARNINGS —
6.7L C
UMMINS DIESEL ENGINE
Diesel Particulate Filter (DPF) Messages
The Cummins diesel engine meets all diesel
emissions standards, resulting in one of the
lowest emitting diesel engines ever produced.
To achieve these emissions standards, your
vehicle is equipped with a state-of-the-art
engine and exhaust system. These systems are
seamlessly integrated into your vehicle and
managed by the Powertrain Control Module
(PCM). The PCM manages engine combustion
to allow the exhaust system’s catalyst to trap
and burn Particulate Matter (PM) pollutants,
with no input or interaction on your part. Your vehicle has the ability to alert you to
additional maintenance required on your
vehicle or engine. The following messages may
display in your instrument cluster display:Perform Service
— Your vehicle will require
emissions maintenance at a set interval. To
help remind you when this maintenance is
due, the instrument cluster display will
display “Perform Service”. When the
“Perform Service” message is displayed in
the instrument cluster display it is necessary
to have the emissions maintenance
performed. Emissions maintenance may
include replacing the Closed Crankcase
Ventilation (CCV) filter element. The proce -
dure for clearing and resetting the "Perform
Service" indicator message is located in the
appropriate Service Information.
Exhaust System — Regeneration Required
Now — "Exhaust Filter XX% Full Safely Drive at
Highway Speeds to Remedy" will be displayed
in the instrument cluster display if the
exhaust particulate filter reaches 80% of its
maximum storage capacity. Under conditions
of exclusive short duration and low speed
driving cycles, your Cummins diesel engine
and exhaust after-treatment system may
never reach the conditions required to
WARNING!
A hot exhaust system can start a fire if you
park over materials that can burn. Such
materials might be grass or leaves coming
into contact with your exhaust system. Do not
park or operate your vehicle in areas where
your exhaust system can contact anything
that can burn.

SERVICING AND MAINTENANCE
SCHEDULED SERVICING — GAS 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 frequent
short-trips, trailer tow, extremely hot or cold
ambient temperatures, and E85 fuel usage will
influence when the “Oil Change Required”
message is displayed. Severe Operating
Conditions can cause the change oil message to
illuminate as early as 3,500 miles (5,600 km)
since last reset. Have your vehicle serviced as
soon as possible, within the next 500 miles
(805 km).

An 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 an authorized dealer, the
message can be reset by referring to the steps
described under “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel”.
NOTE:
Under no circumstances should oil change
intervals exceed 8,000 miles (13,000 km),
12 months or 350 hours of engine run time,
whichever comes first. The 350 hours of engine
run or idle time is generally only a concern for
fleet customers.
Severe Duty All Models
NOTE:
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 environment or
is operated predominantly at idle, or only very
low engine RPM. This type of vehicle use is
considered Severe Duty.
Once A Month Or Before A Long Trip:Check engine oil level
Check windshield washer fluid level
Check tire pressure and look for unusual
wear or damage. Rotate tires at the first sign
of irregular wear, even if it occurs before the
oil indicator system turns on.
Check the fluid levels of the coolant reservoir,
brake master cylinder, power steering and
automatic transmission (six-speed only) and
fill as needed
Check function of all interior and exterior
lights7

390SERVICING AND MAINTENANCE
Inspection and service should also be
performed anytime a malfunction is observed or
suspected. Retain all receipts.
NOTE:
Using white lithium grease, lubricate the door
hinge pivot joints twice a year to prevent prema-
ture wear.
OIL CHANGE INDICATOR SYSTEM —
C
UMMINS 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 display. The oil change
reminder will remind the owner to change the
engine oil every 15,000 miles (24,000 km) or
500 hours, whichever comes first, except for the
Chassis Cab models configured with optional
B20 capability that are using greater than 5%
levels of biodiesel, which are 12,500 miles
(20,000 km) or 400 hours, whichever comes
first. Failure to change the engine oil per the
maintenance schedule can result in internal
engine damage.
An 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 an
authorized dealer, the message can be reset by
referring to the steps described under
“Instrument Cluster Display” in “Getting To
Know Your Instrument Panel” for further
information.
Replace the engine oil and oil filter every
15,000 miles (24,000 km) or 12 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 12 months, whichever comes
first.
NOTE:
Under no circumstances should oil change
intervals exceed 15,000 miles (24,000 km)
or 12 months or 500 hours, whichever
comes first.
Replace the engine oil and oil filter every
12,500 miles (20,000 km) or 400 hours,
whichever comes first when running greater
than 5% levels of biodiesel (Chassis Cab
models configured with optional B20 capa -
bility). If Chassis Cab 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) or
400 hours, whichever comes first under any
circumstances. See the Fuel Requirements
section for more information regarding
operation with biodiesel blend (B6-B20) fuel
meeting ASTM specification D-7467.
PERFORM SERVICE INDICATOR —
C
UMMINS DIESEL
Your vehicle will require emissions
maintenance at a set interval. To help remind
you when this maintenance is due, the
instrument cluster will display “Perform
Service”. When the “Perform Service” message
is displayed on the instrument cluster 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.
