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.

ground, with engine at normal operational temperature.
Check oil level approximately 5 minutes after turning
off the engine, allowing for the oil to return to the oil
pan.
The message “OBSERVE WAITING PERIOD” will be
displayed if the required waiting period has not been
observed after turning off the engine:
• with engine at operational temperature
approximately 5 minutes. •
with engine not at operational temperature up to
approximately 30 minutes.
The engine oil level check can be repeated after a short
time.
Turn the electronic key in starter switch to position 2.

(Canada: 1.0 L)
“ENGINE OIL LEVEL – ADD 1.5 QUART”

See “Adding engine oil level”, on page 318 for
instructions on adding engine oil.
“ENGINE OIL LEVEL – REDUCE OIL LEVEL”
Do not overfill the engine.
Excessive oil must be siphoned or drained off. It could
cause damage to the engine and catalytic converter not
covered by the Mercedes-Benz Limited Warranty. The “MEASURING NOT POSSIBLE” message will be
displayed if a proper oil level check cannot be
performed. The engine oil level check can be repeated
after a short while.
Notes:
See malfunction and warning messages on page 290
and page 299 if an engine oil level indicator appears on
the multifunction display when the engine is running.
The engine oil level cannot be checked while the engine
is running. The “ENGINE OIL LEVEL – NOT WHEN
ENGINE ON” message will appear.
Engine oil consumption
Engine oil consumption checks should only be made
after the break-in period. During the break-in period,
higher oil consumption may be noticed and is normal.
Frequent driving at high engine speeds results in
increased consumption.
