Important!
The FSS indicator is not an engine oil level indicator. 
See page 89 for engine oil level indicator.
Notes:
When disconnecting vehicle battery for one or more 
days at a time, such days will not be counted. Any such 
days not counted by the FSS can be added by your 
Mercedes-Benz Light Truck Center. 
The interval between services is determined by the type 
of driving for which the vehicle is used. 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.
Following a completed A or B service the Mercedes-
Benz Light Truck Center sets the counter mileage to 
10 000 miles (Canada: 15 000 km) and 365 days.
The counter can also be set by any individual. To do so:
1. Turn the key in steering lock to position 2.
2. Immediately press button (1) twice within one 
second.3. The present status for days or distance is displayed. 
Within 10 seconds turn key in steering lock to 
position 0.
4. Press and hold button (1), while turning key in 
steering lock to position 2 again. The present status 
for days or distance is displayed once more. 
Continue to hold button (1).
After approximately 10 seconds a signal sounds, and 
the display shows 10 000 miles (Canada: 15 000 km) 
for approximately 10 seconds.
5. Release button (1).
If the FSS counter was inadvertently reset, have it 
corrected at a Mercedes-Benz Light Truck Center.
Notes:
The FSS allows for distances between 10 000 miles 
(Canada: 15 000 km) and 20 000 miles (Canada: 
30 000 km), or from 365 to 730 days between services.
However you choose to set your reference numbers, the 
scheduled services as posted in the Service Booklet 
must be followed to properly care for your vehicle.
