Continue to follow the instructions in
the DIC messages. Hold the
exhaust brake switch on the center
stack below the climate controls for
more than three seconds, and then
release it, to begin the regeneration
process.
If the EXHAUST BRAKE ON
message displays, then the switch
was released too soon. Press it
again to turn off the exhaust brake,
then try again when the DIC
message prompts.
When manual regeneration begins,
the engine speed increases, the
engine cooling fan sound increases,
and a DIC message indicates that
cleaning is in progress.A DIC message will display when
cleaning is complete. Cleaning
could take up to 30 minutes. Upon
completion, the engine will return to
normal idle, but exhaust
components will remain hot for
several minutes. Do not move the
vehicle until the exhaust has had
time to cool. Manual regeneration
can be canceled at any time by
pressing the brake pedal or by
turning the engine off. Unusual
noises may be heard if regeneration
