The counter can also be set by any individual. To do so:
1. Turn key in steering lock to position 2.
2. Within 1 second press button (1) twice.
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 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. 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.
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.
