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.
For example, maintenance work has to be per-
formed more often than prescribed in the fol-
lowing cases:
R
regular city driving with frequent intermediate
stops
R
driving predominantly short distances
R
frequent operation in mountainous terrain or
on poor road surfaces
R
leaving the engine idling for long periods on a
frequent basis
R
in particularly dusty conditions, or if air-recir-
culation mode is frequently used
In these or similar operating conditions, have
the interior filter, engine air cleaner, engine oil
and oil filter, for example, changed more fre-
quently. If the vehicle is subjected to higher
loads, the tyres must be checked more fre-
quently. You can obtain further information at a
qualified specialist workshop.
Battery disconnection periods
The ASSYST PLUS service interval display can
only calculate the service due date when the
battery is connected.
