sage for a few seconds, e.g.:

Depending on the operating conditions of the
vehicle, the remaining time or distance until the

vice. A number or another letter may be dis-

cialist workshop of this display, you will receive
a statement on the associated costs.

Information about service
Resetting the ASSYST PLUS service
interval display
!
If the ASSYST PLUS service interval display
has been inadvertently reset, this setting can
be corrected at a qualified specialist work-
shop.
Have service work carried out as described in
the Service Booklet. This may otherwise lead
to increased wear and damage to the major
assemblies or the vehicle.
A qualified specialist workshop, e.g. a
Mercedes-Benz Service Centre, 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. Service work 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 intermedi-
ate stops
R
If the vehicle is primarily used to travel short
distances
R
For frequent use in mountainous terrain or on
poor road surfaces
R
If the engine is often left idling for long periods
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. The tyres must be checked more fre-
quently if the vehicle is operated under
increased loads. Further information can be
obtained at a qualified specialist workshop, e.g.
a Mercedes-Benz Service Centre.
Driving abroad
An extensive Mercedes-Benz Service network is
also available in other countries. You can obtain
further information from any Mercedes-Benz
Service Centre.
