Maintenance menu window
! If you confirm maintenance work, without
having it performed according to schedule,
you can damage the vehicle and the assem-
blies. Wear can increase.
If you inadvertently confirm maintenance
work or confirm it too early, the mainte-
nance system calculates the new mainte-
nance due date. To prevent damage to the
vehicle or assemblies, have the correspond-
ing maintenance work performed immedi-
ately.
Only confirm the maintenance work when
the maintenance work has been performed.
The maintenance system calculates mainte-
nance due dates for the vehicle and its assem-
blies based on the vehicle's operating condi-
tions. The event window automatically displays
maintenance due dates 14 days in advance.
When the maintenance due date has been
reached or exceeded, the on-board computer
shows additional event windows
(
Y
page 84).
If the maintenance work is carried out at a
Mercedes-Benz Service Centre, the fact that
the work has been carried out professionally
will be confirmed in the on-board computer
and the service report.
