Diesel Particulate Filter (DPF) Messages
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
WARNING!
not park or operate your vehicle in areas
where your exhaust system can contact
anything that can burn.
Your vehicle has the ability to alert you to
additional maintenance required on your ve-
hicle or engine. Refer to the following mes-
sages that may be displayed on your instru-
ment cluster:
• Exhaust Filter XX% Full Safely Drive at High-
way Speeds to Remedy — This message will
be displayed in the instrument cluster if the
exhaust particulate filter reaches 80% of
its maximum storage capacity. Under con-
ditions of exclusive short duration and low
speed driving cycles, your diesel engine
and exhaust after-treatment system may
never reach the conditions required to
cleanse the filter 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 condition. By simply driving your vehicle at highway
speeds for up to 20 minutes, you can rem-
edy the condition in the particulate filter
system and allow your diesel engine and
exhaust after-treatment system to cleanse
the filter to remove the trapped PM and
restore the system to normal operating con-
dition.
• Exhaust System — Regeneration In Process
Exhaust Filter XX% Full — This message
indicates that the Diesel Particulate Filter
(DPF) is self-cleaning. Maintain your cur-
rent 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.
• Exhaust Service Required — See Dealer Now
— This messages indicates regeneration
has been disabled due to a system malfunc-
67

tion. At this point the engine Powertrain
Control Module (PCM) will register a fault
code, the instrument panel will display a
MIL light.
CAUTION!
See your authorized dealer, as damage to
the exhaust system could occur soon with
continued operation.
• Exhaust Filter Full — Power Reduced See
Dealer — This message indicates the PCM
has derated the engine to limit the likeli-
hood of permanent damage to the after-
treatment system. If this condition is not
corrected and a dealer service is not per-
formed, extensive exhaust after-treatment
damage can occur. To correct this condition
it will be necessary to have your vehicle
serviced by your local authorized dealer. NOTE:
Failing to follow the oil change indicator,
changing your oil and resetting the oil change
indicator by 0 miles remaining will prevent
the diesel exhaust filter from performing it's
cleaning routine. This will shortly result in a
Malfunction Indicator Light (MIL) and re-
duced engine power. Only an authorized
dealer will be able to correct this condition.
CAUTION!
See your authorized dealer, as damage to
the exhaust system could occur soon with
continued operation.

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 pro-
duced. To achieve these emissions stan-
dards, 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 Con-
trol Module (PCM). The PCM manages enginecombustion to allow the exhaust system’s
catalyst to trap and burn Particulate Matter
(PM) pollutants, with no input or interaction
on your part.
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.
Your vehicle has the ability to alert you to
additional maintenance required on your ve-
hicle 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 “Per-
form Service” message is displayed in the
instrument cluster display it is necessary to
have the emissions maintenance per-
formed. Emissions maintenance may in- clude replacing the Closed Crankcase Ven-
tilation (CCV) filter element. The procedure
for clearing and resetting the "Perform Ser-
vice" 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 dis-
play if the exhaust particulate filter reaches
80% of its maximum storage capacity. Un-
der conditions of exclusive short duration
and low speed driving cycles, your Cum-
mins diesel engine and exhaust after-
treatment system may never reach the con-
ditions required to remove the trapped PM.
If this occurs, the “Exhaust Filter XX% Full
Safely Drive at Highway Speeds to Rem-
edy” message will be displayed in the in-
strument cluster display. If this message is
displayed, you will hear one chime to assist
in alerting you of this condition
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 en-
gine and exhaust after-treatment system to

See your authorized dealer, as damage to
the exhaust system could occur soon with
continued operation. •
Exhaust Filter Full — Power Reduced See
Dealer — This message indicates the PCM
has derated the engine to limit the likeli-
hood of permanent damage to the after-
treatment system. If this condition is not
corrected and a dealer service is not per-
formed, extensive exhaust after-treatment
damage can occur. To correct this condition
it will be necessary to have your vehicle
serviced by your local authorized dealer.
NOTE:
Failing to follow the oil change indicator,
changing your oil and resetting the oil change
indicator by 0 miles remaining will prevent
the diesel exhaust filter from performing it's
cleaning routine. This will shortly result in a
Malfunction Indicator Light (MIL) and re-
duced engine power. Only an authorized
dealer will be able to correct this condition.

Vehicles equipped with the Anti-Lock Brake
System (ABS) are also equipped with Elec-
tronic Brake Force Distribution (EBD). In the
event of an EBD failure, the Brake Warning
Light will turn on along with the ABS Light.
Immediate repair to the ABS system is re-
quired.
Operation of the Brake Warning Light can be
checked by turning the ignition switch from
the OFF position to the ON/RUN position.
The light should illuminate for approximately
two seconds. The light should then turn off
unless the parking brake is applied or a brake
fault is detected. If the light does not illumi-
nate, have the light inspected by your autho-
rized dealer.
The light also will turn on when the parking
brake is applied with the ignition switch in
the ON/RUN position.
NOTE:
This light shows only that the parking brake is
applied. It does not show the degree of brake
application.— Vehicle Security Warning Light — If
Equipped
This light will flash at a fast rate for approxi-
mately 15 seconds when the vehicle security
alarm is arming, and then will flash slowly
until the vehicle is disarmed.
— Engine Coolant Temperature Warn-
ing Light
This light warns of an overheated engine
condition. If the engine coolant temperature
is too high, this indicator will illuminate and a
single chime will sound. If the temperature
reaches the upper limit, a continuous chime
will be sound for four minutes or until the
engine is able to cool: whichever comes first.
If the light turns on while driving, safely pull
over and stop the vehicle. If the A/C system is
on, turn it off. Also, shift the transmission
into NEUTRAL and idle the vehicle. If the
temperature reading does not return to nor-
mal, turn the engine off immediately and call
for service. Refer to “If Your Engine Over-
heats” in “In Case Of Emergency” for further
information.
