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
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 instru -
ment cluster display 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 reset -
ting 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 exclu -
sive 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 malfunc -
tion. At this point the engine Powertrain
Control Module (PCM) will register a fault code,
the instrument panel will display a MIL light.

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.
CAUTION!
See an authorized dealer, as damage to
the exhaust system could occur soon with
continued operation.

21_DPF_OM_EN_USC_t.book Page 102

GETTING TO KNOW YOUR INSTRUMENT PANEL103
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 autho-
rized 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 during start up when the ambient
temperature is between -10°F (-23°C) and
-25°F (-32°C).
Engine Power Reduced Up To 2 Min
(Minutes) During Warm up — This message
will display during start up when the ambient
temperature is -25°F (-32°C) and below.
Your vehicle is equipped with an engine
warm up protection feature that may limit
engine performance after cold starting at low
ambient temperatures. The length of time
engine speed is limited is dependent upon
engine coolant temperature. Engine speed
may be briefly limited to 1,000 RPM after
starting with coolant temperature below freezing conditions, and may be limited to
1,000 RPM for up to approximately two
minutes under more severe cold conditions.
Coolant Low
— This telltale will turn on to indi -
cate the vehicle coolant level is low. Refer to
“Dealer Service” in “Servicing And Mainte -
nance” for more information.
Diesel Exhaust Fluid (DEF) Warning
Messages
There are four different messages which are
displayed if the vehicle detects that the DEF
system has been filled with a fluid other than
DEF, has experienced component failures, or
when tampering has been detected. The vehicle
may be limited to a maximum speed of 5 mph
(8 km/h) if the DEF system is not serviced
within less than 200 miles (322 km) of the fault
being detected.
When the DEF system needs to be serviced the
following warnings will display:

DEF Low Refill Soon — This message will
display when the low level is reached, during
vehicle start up, and with increased frequency
during vehicle operation. It will be accompa -
nied by a single chime. Approximately

BATTERY SAVER ON/BATTERY SAVER
M
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.

21_DPF_OM_EN_USC_t.book Page 105

106GETTING TO KNOW YOUR INSTRUMENT PANEL
NOTE:
The charging system is independent from
load reduction. The charging system
performs a diagnostic on the charging
system continuously.
If the Battery Charge Warning Light is on it
may indicate a problem with the charging
system Úpage 108.
The electrical loads that may be switched off
(if equipped), and vehicle functions which can
be affected by load reduction:
Heated Seats/Vented Seats/Heated Wheel
Rear Defroster And Heated Mirrors
HVAC System
115 Volt AC Power Inverter System
Audio and Telematics System
Loss of the battery charge may indicate one or
more of the following conditions:

The charging system cannot deliver enough
electrical power to the vehicle system because
the electrical loads are larger than the capa -
bility of charging system. The charging system
is still functioning properly.

Turning on all possible vehicle electrical
loads (e.g. HVAC to max settings, exterior
and interior lights, overloaded power outlets
+12 Volts, 115 Volt AC, USB ports) during
certain driving conditions (city driving,
towing, frequent stopping).
Installing options like additional lights,
upfitter electrical accessories, audio
systems, alarms and similar devices.
Unusual driving cycles (short trips separated
by long parking periods).
The vehicle was parked for an extended
period of time (weeks, months).
The battery was recently replaced and was
not charged completely.
The battery was discharged by an electrical
load left on when the vehicle was parked.
The battery was used for an extended period
with the engine not running to supply radio,
lights, chargers, +12 Volt portable appli -
ances like vacuum cleaners, game consoles
and similar devices. What to do when an electrical load reduction
action message is present (“Battery Saver On”
or “Battery Saver Mode”)
During a trip:
Reduce power to unnecessary loads if
possible:

Turn off redundant lights (interior or exterior).

Check what may be plugged in to power
outlets +12 Volts, 115 Volt AC, USB ports.

Check HVAC settings (blower, temperature).

Check the audio settings (volume).
After a trip:
Check if any aftermarket equipment was
installed (additional lights, upfitter electrical
accessories, audio systems, alarms) and
review specifications if any (load and Ignition
Off Draw currents).
Evaluate the latest driving cycles (distance,
driving time and parking time).

The vehicle should have service performed if the
message is still present during consecutive trips
and the evaluation of the vehicle and driving
pattern did not help to identify the cause.
