If the FSS counter was inadvertently reset, have a 
Mercedes-Benz Center correct it.Note:
When disconnecting vehicle battery for one or more 
days at a time, such days will not be counted. Any such 
days not counted by FSS can be added by your 
Mercedes-Benz Center.
The interval between services is determined by the kind 
of vehicle operation. For example driving at extreme 
speeds, and cold starts combined with short distance 
driving in which the engine does not reach normal 
operating temperature, reduce the interval between 
services.
