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 š appears in the main odometer
display field prior to the next suggested service.
Depending on operating conditions throughout the year,
the next service is calculated and displayed in days
š or distance 9 remaining.The symbols 9 or ´ indicate the type of service
to be performed:
9Service A
´Service B
The message is displayed for approximately 10 seconds
when turning the key in steering lock to position 2, or
while driving when reaching the service warning
threshold. It can be canceled manually by pressing
button (1).
Once the suggested term has passed, the message plus
symbol 9 or š, preceded by a – (minus symbol)
blinks for approx. 30 seconds and a signal sounds every
time when turning the key in steering lock to position 2.
The FSS display can also be called up for approx.
10 seconds with display illuminated by pressing
button (1) twice within 1 second.
Following a completed A or B service the Mercedes-Benz
Center sets the counter to 10 000 miles (Canada: 15 000
km) and 365 days.

3. The present status for days or distance is displayed.
Within 10 seconds turn key in steering lock to

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 approx. 10 seconds a signal sounds, and the
display shows 10 000 miles (Canada: 15 000 km) for
approx. 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. 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.

Engine oils are specifically tested for their suitability in
our engines. Therefore, use only engine oils
recommended by Mercedes-Benz. Information on
recommended brands is available at your authorized
Mercedes-Benz Center.
Please follow Service Booklet recommendations for
scheduled oil changes. Failure to do so could result in
engine damage not covered by the Mercedes-Benz
Limited Warranty.
Engine oil additives
Do not blend oil additives with engine oil. They may be
harmful to the engine operation.
Damage or malfunctions resulting from blending oil
additives are not covered by the Mercedes-Benz Limited
War ra nt y.Air conditioner refrigerant
R-134a (HFC) refrigerant and special PAG lubricating oil
is used in the air conditioner system.
Never use R-12 (CFC) or mineral-based lubricating oil,
otherwise damage to the system will occur.
Brake fluid
During vehicle operation, the boiling point of the brake
fluid is continuously reduced through the absorption of
moisture from the atmosphere. Under extremely hard
operating conditions, this moisture content can lead to
the formation of bubbles in the system thus reducing
the system‘s efficiency.
The brake fluid must therefore be replaced every two
years, preferably in the spring.
It is recommended to use only brake fluid approved by
Mercedes-Benz. Your authorized Mercedes-Benz Center
will provide you with additional information.
