interva ldisplay !
If the ASSYST PLUS service interval display
has been inadvertently reset, this setting can
be corrected at aqualified specialist work-
shop.
Have service work carried out as described in the Servic eBooklet .This may otherwise lead
to increased wear and damage to the major

Aq ualified specialist workshop, e.g. a
Mercedes-Benz Servic eCentre, will reset the
ASSYST PLUS service interval display after the
service work has been carried out. You can also
obtain further information on maintenance
work, for example.
Special service requirements The prescribed service interval is based on nor-
mal operation of the vehicle. Servic ework will
need to be performed more often if the vehicle is
operated under arduous conditions or increased loads, for example:
R regular city driving with frequent intermediate
stops
R if the vehicle is primarily used to travel short
distances
R for frequent operation in mountainous terrain
or on poor road surfaces
R if the engine is often left idling for long periods
In these or similar operating conditions, have,
for example, the air filter, engine oil and oil filter changed more frequently. The tyres must be
checked more frequently if the vehicle is oper-
ated under increased loads. Further informationcan be obtained at aqualified specialist work-
shop, e.g. aMercedes-Benz Servic eCentre. Driving abroad An extensive Mercedes-Benz Servic
