Copied & pasted from 2012 owners manual. Hope this helps.

Exhaust System – Regeneration Required Now
“Exhaust System—Regeneration Required Now” will be
displayed on the Electronic Vehicle Information Center
(EVIC) 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 System
— Regeneration Required Now” message will be displayed
in the EVIC. 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 Completed

will hear one chime to assist in alerting you of this condition.
