Special service requirements
The prescribed service interval is based on nor‐
mal vehicle use. Maintenance work will need to
be performed more often than prescribed if the
vehicle is operated under arduous conditions or
increased loads.
Examples of arduous operating conditions:
R
regular city driving with frequent intermediate
stops
R
mainly short-distance driving
R
frequent operation in mountainous terrain or
on poor road surfaces
R
when the engine is often left idling for long
periods
R
operation in particularly dusty conditions
and/or if air-recirculation mode is frequently
used
In these or similar operating conditions, have the
interior air filter, engine air cleaner, engine oil and
oil filter etc. changed more frequently. If the vehi‐
cle is subjected to higher loads, the tyres must
be checked more frequently. Further information
can be obtained at a qualified specialist work‐
shop.
Battery disconnection periods
The ASSYST PLUS service interval display can
only calculate the service due date when the
battery is connected.
#
Note down the service due date displayed on
the instrument display before disconnecting
the battery (
