112 GETTING TO KNOW YOUR INSTRUMENT PANEL
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 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 procedure 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-treat-
ment system may never reach the conditions required
to remove the trapped Particulate Matter (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 Particulate Matter (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 regenera-
tion 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.
CAUTION!
See an 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.
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 its 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.
CAUTION!
See an authorized dealer, as damage to the exhaust
system could occur soon with continued operation.
