Fuel and exhaust gas cleaning
This procedure involves an autonomous par-
ticulate filter cleaning process and may take
some time.
If the warning lamp does not turn o, go imme-
diately to a specialised workshop to repair the
fault.
WARNING
Always adjust your speed to suit the weather
conditions, roads, braking distance and traf-
fic if the particulate filter is in its regeneration
phase. Route recommendations should never
make you disregard each country's specific
trac regulations.
Note
If during the particulate filter regeneration
process you also get a fuel reserve warning
, the process may be interrupted. Refuel
and continue with the particulate filter re-
generation process.
NOTICE
●
When the exhaust system detects that the
particulate filter is close to saturation, the
self-cleaning function of this system recom-
mends optimal driving for this function.
●
Due to the high temperatures caused by
the regeneration of the particulate filter, it is
possible that the radiator fan will activate af-
ter stopping the engine, even it its operating
temperature has not been reached.
●
Noise, smells and high idle speeds can oc-
cur during regeneration.
●
Always use the correct engine oil and the
correct fuel to make sure the useful life of the
particulate filter is not aected. Also avoid
making short trips all the time.
