Description of Indicator Based Service [A - H]

Flexible service system (FSS) (service indicator)

Service Symbols:

The FSS permits a flexible service schedule that is directly related to the operating conditions of the vehicle.

The service symbol 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 or distance remaining.

The symbols or indicate the type of service to be performed.

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 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: 15,000km) and 365 days.

The counter can also be set by any individual. To do so:
1. Turn key in steering lock to position 2.
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 position 0.
4. Press and bold 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: 15,000km) 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.
