i
If the service indicator was inadvertent-
ly reset, have a Mercedes-Benz Light
Truck Center correct it.
Only reset if the proper service has
been performed. Resetting the system
without performing the proper service
as called for by the FSS will cause the
FSS to incorrectly determine the next
service interval which will result in en-
gine 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
