The next service due date is displayed either in days or
in miles, depending on your driving style.
Once the suggested service term has passed, the symbol
and message appear for approximately 30 seconds and
a signal sounds every time when turning the electronic
key in starter switch to position 2.
The service indicator disappears automatically after
30 seconds or if the knob for instrument cluster
illumination, see page 96, in the instrument cluster is
pressed.
Calling up service indicator manually:
Turn the electronic key in starter switch to position 1
or 2.
Call up the trip odometer and main odometer by
pressing button
è or ÿ on the multifunction
steering wheel until the display appears. See page 106.
Press button j or k until the FSS indicator
appears.
The next or previous system is displayed by pressing
button è or ÿ . Important!
The FSS indicator is not an engine oil level indicator.
See page 141 for engine oil level indicator.
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 the FSS can be added by your
Mercedes-Benz 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 operating normal temperature, reduce the interval
between services.
