Resetting the ASSYST PLUS service
interval display
!
If the ASSYST PLUS service interval dis-
play has been inadvertently reset, this set-
ting can be corrected at a qualified special-
ist workshop.
Have service work carried out as described
in the Maintenance Booklet. This may oth-
erwise lead to increased wear and damage
to the major assemblies or the vehicle.

after the service work has been carried out.

Special service requirements
The specified maintenance interval takes only
the normal operation of the vehicle into
account. Service work will need to be per-
formed more often if the vehicle is operated
under arduous conditions or increased loads.
This can be the case, for example, when driv-
ing frequently in mountainous areas or on
poor road surfaces.
Under arduous operating conditions, the tires
must be checked more often. Further infor-
mation can be obtained at a qualified special-
ist workshop, e.g. an authorized Mercedes-
Benz Center.
