Instrument Panel - Alfa Romeo GIULIETTA Owner's Handbook Manual

During standard use of the vehicle, the
engine control unit records a set of data
(e.g.: travel time, type of route,
temperatures, etc.) and it will then
calculate how much particulate has
been trapped by the filter.
Since this filter physically traps
particulate, it should be periodically
regenerated (cleaned) at regular
intervals by burning carbon particles.
The regeneration procedure is
controlled automatically by the engine
management control unit according
to the filter conditions and vehicle use
conditions.
During the regeneration there may be a
limited increase in the engine idle
speed, fan activation, a limited increase
in fumes and high temperatures at the
exhaust.
These are not faults; they do not impair
normal car performance or damage
the environment. If the dedicated
message is displayed, see contents of
"Warning lights and messages"
paragraph, in chapter "Knowing the

instrument panel".
