Flexible Service System (FSS)




The FSS permits a flexible service schedule that is dire
ctly related to the operating conditions of the vehicle.
The symbol
or appears in the main odometer field prior to the next suggested service. Depending on operating
conditions throughout the year, the nex t service is calculated and displayed in days or distance remaining. The
message is displayed for approx. 10 seconds when turning the electronic key in steering lock to position 2, or it can
be canceled manually by pressing button 0. Once the suggested term has passed, the message plus symbol
or
, preceded by a - (minus symbol) blinks, when turning t he electronic key to position 2. The FSS display can also
be called up for approx.10 seconds with display illuminated by pressing button 0 twice. Following a completed service
the Mercedes-Benz dealer sets the counter to 10 000 miles (Canada: 15 000 km) and 365 days.

The counter can also be set by any individual. To do so:
1 . Turn electronic key in steering lock to position 2.
2 . Within 4 seconds press button 0 twice.
3 . The present status for days or distance is displayed. Within 10 seconds turn electronic key in steering lock to
position 0.
4 . Press and hold button 0, while turning electronic key in steering lock to position 2 again. The present status for
days or distance is displayed once more. Continue to hold button 0 After approx. 10 seconds a signal sounds, and the

5 . Release button 0. If the FSS counter was inadvertently reset, have a Mercedes -Benz dealer correct it.

Notes:
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 de aler. 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 temperat ure, reduce the interval between services.

Model C 230:
The FSS allows for distances between 10 000 miles (Canada: 15 000 km) and 15 000 miles (Canada: 22 500 km),
or from 365 to 730 days between services.

Models C 280 and C 43 AMG:
The FSS allows for distances between 10 000 miles (Canada: 15 000 km) and 20 000 miles (Canada: 30 000 km),
or from 365 to 730 days 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.

connecting, you might get injured. Battery fluid contains sulfuric acid. Do not allow this fluid to come in
contact with eyes, skin or clothing. In case it does, immediately flush affected area with water and seek
medical help if necessary. A battery will also produ ce hydrogen gas, which is flammable and explosive.
Keep flames or sparks away from battery, avoid im proper connection of jumper cables, smoking etc..

Important !
Battery maintenance information:
The battery is located in the trunk under the trunk floor. The fluid level must be checked at every A and B service.
Always insure that the fluid level is at the specified maximum level and that only distilled water is used. Failure to
maintain proper fluid level may result in cell deterioration and possible battery rupture. The service life of the battery is
dependent on its condition of charge. The battery should alwa ys be kept sufficiently charged, in order to last an
optimum length of time.
Therefore, we strongly recommend that you have the battery charge checked frequently, and corrected if
necessary, especially if you use the vehicle less than approximately 200 miles (300 km) per month, mostly for
short distance trips, or if it is not used for long periods of time.
Only charge a battery with a battery charger after the battery has been disconnected from the vehicle electrical circuit.
Always disconnect the battery negative lead first and connect last. When removing and connecting the battery,
always make sure that all electrical consumers are off and the electronic key is in steering lock position 0. The battery
and its vent tube must always be securely installed when the car is in operation. While the engine is running the
battery terminal clamps must not be loosened or detached, otherwise the generator and other electronic components
would be damaged.

Note:
After reconnecting the battery al so resynchronize the Express feature of the power windows
(see Power Windows in Index).
