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
• 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 Cum-
mins® diesel engine and exhaust after-treatment sys-
tem to remove the trapped PM and restore the system
to normal operating condition. •

The main display area will normally display the main
menu or the screens of a selected feature of the main
menu. The main display area also displays “pop up”
messages that consist of approximately 60 possible warn-
ing or information messages. These pop up messages fall
into several categories:
•Five Second Stored Messages
When the appropriate conditions occur, this type of
message takes control of the main display area for five
seconds and then returns to the previous screen. Most of
the messages of this type are then stored (as long as the
condition that activated it remains active) and can be
reviewed from the “Messages” main menu item. As long
as there is a stored message, an “i” will be displayed in
the DID’s compass/outside temp line. Examples of this
message type are “Right Front Turn Signal Lamp Out”
and “Low Tire Pressure”. •
Unstored Messages
This message type is displayed indefinitely or until the
condition that activated the message is cleared. Examples
of this message type are “Turn Signal On” (if a turn signal
is left on) and “Lights On” (if driver leaves the vehicle).
• Unstored Messages Until RUN
These messages deal primarily with the Remote Start
feature. This message type is displayed until the ignition
is in the RUN state. Examples of this message type are
“Remote Start Aborted - Door Ajar” and “Press Brake
Pedal and Push Button to Start”.
• Five Second Unstored Messages
When the appropriate conditions occur, this type of mes-
sage takes control of the main display area for five seconds
and then returns to the previous screen. An example of this
message type is “Automatic High Beams On”.
