indicator 
In the event that the maintenance service 
on your vehicle is not carried out by an 
authorized Mercedes-Benz Light Truck 
Center, you can have the maintenance 
service indicator reset. The automotive 
maintenance facility carrying out the 
maintenance service will find the informa-
tion for resetting the maintenance service 
indicator in the maintenance-relevant 
literature for your vehicle. Such literature 
is available either from either an 
authorized Mercedes-Benz Light Truck 
Center or directly from Mercedes-Benz.
iThe menu overview can be found on 
(
page 160).
iIf 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 
message or maintenance service indicator 
display.
!If the maintenance service indicator was 
inadvertently reset, have an authorized 
Mercedes-Benz Light Truck Center correct it.
Only reset if the proper maintenance service has 
been performed. Resetting the system without 
performing the proper 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.
