indicator 
In the event that the maintenance service 
on your vehicle is not carried out by an au-
thorized Mercedes-Benz Center, you can 
have the maintenance service indicator re-
set. The automotive maintenance facility 
carrying out the maintenance service will 
find the information for resetting the main-
tenance service indicator in the mainte-
nance-relevant information for your 
vehicle. Such information is available from 
either your authorized Mercedes-Benz 
Center or directly from Mercedes-Benz.
iIf the battery is disconnected, the days 
of disconnection will not be included in 
the count shown by the maintenance 
service indicator. To arrive at the true 
maintenance service deadline, you will 
need to subtract these days from the 
days shown in the maintenance service 
indicator message or maintenance ser-
vice indicator display.
Do not confuse the maintenance ser-
vice indicator with the engine oil level 
indicator :.
