(service indicator)
The FSS permits a flexible service schedule that is
directly related to the operating conditions of the
vehicle.
The symbol 9 or ´ appea rs in t he m ain 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 ´ preceded by a – (minus symbol)
blinks for approximately 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 approximately
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.

2.Within 4 seconds press button (1) twice.
3.The present status for days or distance is displayed.
Within 10 seconds turn key in steering lock to

for days or distance is displayed once more.
Continue to hold button (1).
After approximately 10 seconds a signal sounds, and
the display shows 10 000 miles (Canada: 15 000 km)
for approximately 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. 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.

accident, system settings should be entered with
the vehicle at standstill and systems should be
operated by the driver only when traffic conditions
permit. Always pay full attention to traffic
conditions first before operating system controls
while driving. Bear in mind that at a speed of just 30 mph
(approximately 50 km / h), your car is covering a
distance of approximately 50 feet (approximately
14 m ) e v e r y s e c o n d .
