Resetting the maintenance service 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
reset. The automotive maintenance facility
carrying out the maintenance service will
find the information for resetting the
maintenance service indicator in the main-
tenance-relevant information for your vehi-
cle. Such information is available either
from an authorized Mercedes-Benz Center
or directly from Mercedes-Benz.
i
If the battery supplying the vehicle’s electri-
cal consumers is disconnected, the days of dis-
connection 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 indicator N.
!
If the maintenance service indicator was in-
advertently reset, have an authorized
Mercedes-Benz Center correct it.
Only reset if the proper maintenance service has
been performed. Resetting the system without
performing 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.
