Flexible service system (FSS)
(service indicator)
The FSS permits a flexible service schedule that is 
directly related to the operating conditions of the 
vehicle.
The symbol 9 or ½ appears together with a 
message in the multifunction indicator prior to the next 
suggested service.
Dep end in g on  oper atin g c ond ition s t hr oughout t he year, 
the next service is calculated and displayed in days or 
distance remaining.The message is displayed for approximately 10 seconds 
when turning the electronic key in steering lock to 
position 2, or while driving when reaching the service 
warning threshold.
The symbols and messages indicate the type of service 
to be performed:
9Service A
½Service B
One of the following messages will appear in the display 
(e.g. Service A):
“SERVICE A – IN xx DAYS”
“SERVICE A – IN xx MILES” (Canada: KM)
“SERVICE A – EXCEEDED BY xx DAYS”
“SERVICE A – EXCEEDED BY xx MILES” (Canada: KM)
“SERVICE A – DUE NOW”
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 steering lock to position 2.

30 seconds or if buttonJon the instrument cluster is 
pressed.
Calling up service indicator manually:
Turn the electronic key in steering lock to position 
1or2.
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 96.
Press button j or k until the FSS indicator 
appears. 
Pressing the è or ÿ button displays the next or 
previous system.
Important!
The FSS indicator is not an engine oil level indicator. 
See page 117 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.

The counter can also be set by any individual. To do so:
Turn the electronic key in steering lock to position 2.
To call up the trip odometer and main odometer, press

sounds. The message “SERVICE INTERVAL HAS BEEN 
RESET” appears in the multifunction display.
The new service indicator is displayed with the reset 
distance of 10 000 miles (Canada 15 000 km).
If the FSS counter was inadvertently reset, have a 
Mercedes-Benz Center correct it.
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.

incorrect reading will be displayed if you do not cancel 
the measurement. Move the vehicle to level ground and 
measure again.

One of the following messages will subsequently appear 
on the indicator:
“ENGINE OIL LEVEL – O.K.”
No oil needs to be added.
“ENGINE OIL LEVEL – ADD 1.0 QUART”
(Canada: 1.0 L)
“ENGINE OIL LEVEL – ADD 1.5 QUART”
(Canada: 1.5 L)
“ENGINE OIL LEVEL – ADD 2.0 QUART”
(Canada: 2.0 L)
See page 262 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 message “MEASURING NOT POSSIBLE” will be 
displayed if a proper oil level check cannot be 
performed. The engine oil level check can be repeated 
after a short time.Perform the engine oil level check with the dipstick, if it 
cannot be completed via the multifunction display.
See page 262.
In this case we recommend that you have the system 
checked at a Mercedes-Benz Center.
Note:
See “Malfunction and warning messages” on page 240 
and page 251 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.
