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 vehicle or engine. Refer to
the following messages that may be displayed on your
EVIC or DID:
• Perform Service — Your vehicle will require emissions
maintenance at a set interval. To help remind you
when this maintenance is due, the Cluster will display
“Perform Service”. When the “Perform Service” mes-
sage is displayed on the EVIC/DID it is necessary to
have the emissions maintenance performed. Emissions maintenance may include replacing the Closed Crank-
case Ventilation (CCV) filter element. The procedure
for clearing and resetting the
Perform Serviceindica-
tor 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 Cluster if
the exhaust particulate filter reaches 80% of its maxi-
mum 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 EVIC/DID.
If this message is displayed, you will hear one chime to
assist in alerting you of this condition
234 UNDERSTANDING YOUR INSTRUMENT PANEL

•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.
• Exhaust Service Required — See Dealer Now — This
messages 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.
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 likelihood of permanent damage to
the after-treatment system. If this condition is not
corrected and a dealer service is not performed, exten-
sive exhaust after-treatment damage can occur. To
correct this condition it will be necessary to have your
vehicle serviced by your local authorized dealer.

varnish to form on piston rings, engine valves, and
injector nozzles. Also, the unburned fuel can enter the
crankcase, diluting the oil and causing rapid wear to the
engine.
If the engine is allowed to idle, under some conditions
the idle speed may increase to 900 RPM then return to
normal idle speed. This is normal operation.
NOTE:For EVIC/DID messages related to the vehicle’s
exhaust system, refer to “Electronic Vehicle Information
Center (EVIC)” or “Driver Information Display (DID)”
for further information.
Idle-Up Feature — Automatic Transmission Only
The driver-controlled high idle speed feature will help
increase cylinder temperatures and provide additional
cab heat, however, excessive idling may still cause the
exhaust aftertreatment system to not properly regenerate.
Extended periods of idle time should be avoided. The Idle-Up feature uses the speed control switches to
increase engine idle speed and quickly warm the vehi-
cle’s interior.
1. With the transmission in PARK, the parking brake
applied, and the engine running, push the speed
control switch to the ON position, then push the SET
switch.
2. The engine RPM will go up to 1100 RPM. To increase the RPM, push and hold the ACCEL/RESUME switch
and the idle speed will increase to approximately 1500
RPM. To decrease the RPM, push and hold the DECEL
switch and the idle speed will decrease to approxi-
mately 1100 RPM.
3. To cancel the Idle–Up feature, either push the CAN- CEL switch, push the ON/OFF switch, or press the
brake pedal.

•Use of biodiesel mixture in excess of 20% can nega-
tively impact the fuel filter’s ability to separate water
from the fuel, resulting in high pressure fuel system
corrosion or damage.
• Ethanol blends are not recommended or approved for
use with your Cummins diesel engine.
• In addition, commercially available fuel additives are
not necessary for the proper operation of your Cum-
mins diesel engine.
Intervention Regeneration Strategy — Message
Process Flow
The Cummins diesel engine meets all EPA Heavy Duty
Diesel Engine 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. The engine and exhaust after-treatment system work together to achieve the EPA Heavy Duty Diesel
Engine Emissions Standards. These systems are seam-
lessly integrated into your vehicle and managed by the
Cummins Powertrain Control Module (PCM). The PCM
manages engine combustion to allow the exhaust sys-
tem’s catalyst to trap and burn Particulate Matter (PM)
pollutants, with no input or interaction on your part.
Additionally, your vehicle has the ability to alert you to
additional maintenance required on your truck or engine.
Refer to “Electronic Vehicle Information Center (EVIC)”
or “Driver Information Display (DID)” in “Understand-
ing Your Instrument Panel” for further information.

A hot exhaust system can start a fire if you park over
materials that can burn. Such materials might be
