Diesel Messages And Warnings — 6.7L
Cummins 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 addi
-
tional 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 remove the trapped PM. If this occurs, the
“Exhaust Filter XX% Full Safely Drive at
Highway Speeds to Remedy” message will be
displayed in the instrument cluster display. If
this message is displayed, you will hear one
chime to assist in alerting you of this condi
-
tion
By simply driving your vehicle at highway
speeds for as little as 45 minutes, you can
remedy the condition in the particulate filter
system and allow your Cummins diesel
engine and exhaust after-treatment system
to remove the trapped PM and restore the
system to normal operating condition.
Exhaust System — Regeneration In Process
Exhaust Filter XX% Full — Indicates that the
Diesel Particulate Filter (DPF) is self-cleaning.
Maintain your current driving condition until
regeneration is completed.
Exhaust System — Regeneration Completed
— This message indicates that the Diesel
Particulate Filter (DPF) self-cleaning is
completed. If this message is displayed, you
will hear one chime to assist in alerting you of
this condition.
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 indi-
cator 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 Condi-
tions can cause the change oil message to illu -
minate 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 sched
-
uled oil change. If a scheduled oil change is
performed by someone other than an autho -
rized dealer, the message can be reset by refer -
ring to the steps described under “Instrument
Cluster Display” in “Getting To Know Your
Instrument Panel” for further information.
Gas Engines:
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:
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 predominately at idle or very low
engine RPM. This type of vehicle use is consid -
ered Severe Duty. 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. Rotate at the
first sign of irregular wear.
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
lights.

SERVICING AND MAINTENANCE335
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 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 sched -
uled oil change. If a scheduled oil change is
performed by someone other than an autho -
rized dealer, the message can be reset by refer -
ring 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 opera -
tion with biodiesel blend (B6-B20) fuel meeting
ASTM specification D-7467.

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
