setting can be corrected at a qualified
specialist workshop.
Have
service work carried out as described
in the Maintenance Booklet. This may
otherwise lead to increased wear and
damage to the major assemblies or the
vehicle.
A qualified specialist workshop, e.g. an
authorized Mercedes-Benz Center, will reset
the ASSYST PLUS service interval display

Special service requirements
Arduous operating conditions or increased
loads on the vehicle will require some service
work to be performed more often than for a
vehicle in normal use. Such arduous
conditions include regular city driving with
frequent intermediate stops and use in
mountainous terrain or on poor road
surfaces.
For example, if the vehicle is used under
arduous operating conditions, have air filters, engine oil and oil filters changed frequently
and check the wheels often. Further
information can be obtained at a qualified
specialist workshop, e.g. an authorized
Mercedes-Benz Center.
Driving abroad
An
extensive Mercedes-Benz Service network
is also available in other countries. You can
obtain further information from any
authorized Mercedes-Benz Center. Care
