DIESEL MESSAGES AND WARNINGS
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 emis -
sions 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 Ventila -
tion (CCV) filter element. The procedure for
clearing and resetting the "Perform Service"
indicator message is located in the appropriate
Service Information.

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.

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
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 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 DPF
is self-cleaning. Maintain your current driving
condition until regeneration is completed.
Exhaust System — Regeneration Completed —
This message indicates that the 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 message indicates regeneration has been
disabled due to a system malfunction. At this
point the engine Powertrain Control Module
(PCM) will register a fault code, the instrument
panel will display a MIL light.
Exhaust Filter Full — Power Reduced See
Dealer — This message indicates the PCM has
derated the engine to limit the likelihood of
permanent damage to the after-treatment
system. If this condition is not corrected and a
dealer service is not performed, extensive
exhaust after-treatment damage can occur. To
correct this condition it will be necessary to have
your vehicle serviced by an 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 reduced engine power. Only an authorized
dealer will be able to correct this condition.
Cold Ambient Derate Mode Messages
The vehicle will display messages when a derate
(engine power reduction) is activated to protect the
engine during start-up in cold ambient
temperatures.
Engine Power Reduced During Warm-up — This
message will display during start-up when the
ambient temperature is between 10°F (-12°C)
and -10°F (-23°C).
Engine Power Reduced Up To 30 Sec (Seconds)
During Warm-up — This message will display

ODE MESSAGE — ELECTRICAL LOAD
R
EDUCTION ACTIONS — IF EQUIPPED
This vehicle is equipped with an Intelligent Battery
Sensor (IBS) to perform additional monitoring of
the electrical system and status of the vehicle
battery.
In cases when the IBS detects charging system
failure, or the vehicle battery conditions are
deteriorating, electrical load reduction actions will
take place to extend the driving time and distance
of the vehicle. This is done by reducing power to or
turning off non-essential electrical loads.
Load reduction is only active when the engine is
running. It will display a message if there is a risk
of battery depletion to the point where the vehicle
may stall due to lack of electrical supply, or will not
restart after the current drive cycle.
When load reduction is activated, the message
“Battery Saver On Some Systems May Have
Reduced Power” will appear in the instrument
cluster.
These messages indicate the vehicle battery has a
low state of charge and continues to lose electrical
charge at a rate that the charging system cannot
sustain.
