The FSS indicator is not an engine oil level indicator.
See page 96 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).
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.
Note:
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.
