Wa r n i n g !
USE SEAT BELTS PROPERLY.• Seat belts can only work when used properly.
Never wear seat belts in any other way than as
described in this section, as that could result
in serious injuries in case of an accident.• Each occupant should wear their seat belt at all
times, because seat belts help reduce the
likelihood of and potential severity of injuries
in accidents, including rollovers. The
integrated restraint system includes “SRS”
(driver airbag, passenger airbag, door mounted
side impact airbags), “ETR” (seat belt
emergency tensioning retractors), and driver
knee bolster. The system is designed to
enhance the protection offered to properly
belted occupants in certain frontal (front
airbags) and side (side impact airbags) impacts
which exceed preset deployment thresholds.

(service indicator)
The FSS permits a flexible service schedule that is
directly related to the operating conditions of the
vehicle.
The symbol 9 or ´ 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 ´ 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).

The counter can also be set by any individual. To do so:
1. Turn key in steering lock to position 2.
2. Within 1 second press button (1) twice.
3. The present status for days or distance is displayed.
Within 10 seconds turn key in steering lock to
position 0.
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 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.
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.
