339 Operation
Maintenance
Resetting the maintenance service 
indicator 
In the event that the maintenance service 
on your vehicle is not carried out by an 
authorized Mercedes-Benz Center, you can 
have the maintenance service indicator 
reset. 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 literature for your vehicle. 
Such literature is available from any autho-
rized 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 service indicator dis-
play.
Do not confuse the maintenance service indica-
tor with the engine oil level indicatorN.
iIf the maintenance service indicator was 
inadvertently reset, have an authorized 
Mercedes-Benz Center correct it.
Only reset if the proper maintenance service has 
been performed. Resetting the system without 
performing the proper maintenance service as 
called for by the maintenance service indicator 
will result in engine damage and/or other vehicle 
damage not covered by the Mercedes-Benz 
Limited Warranty.
