Maintenance
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 Light Truck
Center, you can have the maintenance ser-
vice indicator reset. The automotive main-
tenance facility carrying out the
maintenance service will find the informa-
tion for resetting the maintenance service
indicator in the maintenance-relevant in-
formation for your vehicle. Such informa-
tion is available from either your
authorized Mercedes-Benz Light Truck
Center or directly from Mercedes-Benz.i
If 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.
Do not confuse the maintenance ser-
vice indicator with the engine oil level
indicator :.
i
If the maintenance service indicator
was inadvertently reset, have an autho-
rized Mercedes-Benz Light Truck
Center correct it.
Only reset if the proper maintenance
service has been performed. Resetting
the system without performing the
proper maintenance service as called
for by the maintenance service indica-
tor will result in engine damage and/or
other vehicle damage not covered by
the Mercedes-Benz Limited Warranty.
