Only use DEF according to ISO 22241. Do
not add special additives to DEF or dilute it
with water. This can damage the BlueEFFI-

exhaust gas aftertreatment. Description of maintenance work for
the exhaust system
The composition of exhaust emissions is
influenced not only by the exhaust gas after-
treatment system, but also by various engine
parts and their settings.
Maintenance of the exhaust system must
therefore include these engine parts. Some
maintenance jobs are actually only tests.
They are important, however, because they
allow early detection of discrepancies which
can later lead to increased exhaust emis-
sions. It is generally less costly to adjust devi-
ations of this sort immediately than to wait
until they incur high repair costs. The main-
tenance intervals have been determined so
that the vehicle, under normal operating con-
ditions, should operate properly between
maintenance services. Changing the engine oil and filter
Change the engine oil and oil filter every
15,000 miles. If oil consumption should
increase, determine the cause and take nec-
essary corrective steps. Do not reset the
service interval display if the oil level is filled
up or the oil is changed at times other than
the recommended intervals. Replacing the air filter
In normal dust conditions, replace the air fil-
ter every 45,000 miles. Clean the air filter cap
and housing before removing the air filter. Replacing the fuel filter
Replace the fuel filter every 30,000 miles Checking the diesel particle filter
The saturation level of the diesel particle filter
must first be checked at 90,000 miles.
If the saturation level is still below the thresh-
old value at 90,000 miles, the saturation level
of the diesel particle filter must be checked
again at each subsequent oil service plus/
maintenance service.
If the level of the diesel particle filter is above
the limit value, the diesel particle filter should
be replaced.
Once the new diesel particle filter has been
installed, the checking cycle starts again after
90,000 miles. Checking and adding DEF
Check and add DEF every 15,000 miles. Maintenance service
Vehicle maintenance work (including
exhaust system maintenance)
i The maintenance services should be car-
ried out at the specified mileage or after the
specified number of years (whichever
comes first).
