To confirm, hold down the reset knob

The service indicator now displays the
reset interval.
iIf the vehicle battery is disconnected,
the days of disconnection will not be in-
cluded in the count shown by the ser-
vice indicator. To arrive at the true
service deadline, you will need to sub-
tract these days from the days shown
in the service indicator.
Do not confuse the service indicator

iIf 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 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.
