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 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 the maintenance
service indicator display.
Do not confuse the maintenance ser-
vice indicator with the engine oil level
indicatorù.
iIf the maintenance service indicator
was inadvertently reset, have an autho-
rized Mercedes-Benz Center correct it.
Only reset if the proper maintenance
service has been performed. Resetting
the system without performing the
proper service as called for by the
maintenance service indicator will re-
sult in engine damage and/or other
vehicle damage not covered by the
Mercedes-Benz Limited Warranty.
