been performed. Resetting the system 
without performing proper service as 
called for by the FSS will cause the FSS 
to incorrectly determine the next ser-
vice interval which will result in engine 
damage not covered by the Mer-
cedes-Benz Limited Warranty. 
If the battery is disconnected, the days 
of disconnection will not be included in 
the count shown by the service indica-
tor. To arrive at the true service dead-
line, you will need to subtract these 
days from the days shown in the ser-
vice indicator.
Do not confuse the service indicator 
with the engine oil level indicator
