Important!
The FSS indicator is not an engine oil level indicator.
See page 89 for engine oil level indicator.
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 Light Truck Center.
The interval between services is determined by the type
of driving for which the vehicle is used. 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.
Following a completed A or B service the Mercedes-
Benz Light Truck Center sets the counter mileage 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 the key in steering lock to position 2.
2. Immediately press button (1) twice within one
second.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 it
corrected at a Mercedes-Benz Light Truck Center.
Notes:
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.

The more cautiously you treat your vehicle during the
break-in period, the more satisfied you will be with its
performance later on. Therefore, drive your vehicle
during the first 1 000 miles (1 500 km) at moderate
vehicle and engine speeds.
During this period, avoid heavy loads (full throttle
driving) and excessive engine speeds.
Avoid accelerating by kickdown. It is not recommended
to brake the vehicle by manually shifting to a lower gear.
We recommend that you select positions “3”, “2” or “1”
only at moderate speeds (for hill driving).
After 1 000 miles (1 500 km) speeds may be gradually
increased to the permissible maximum.Maintenance
Approximately 30 days or 2 000 miles
(Canada: 2000 km) prior to the next recommended
service, the remaining distance or days are displayed in
the multifunction indicator. See Flexible Service System
(FSS) on page 87.
We strongly recommend that you have your vehicle
serviced by your authorized Mercedes-Benz Light Truck
Center, in accordance with the Service Booklet at the
times called for by the FSS.
Failure to have the vehicle maintained in accordance
with the Service Booklet at the designated times /
mileage may result in vehicle damage not covered by
the Mercedes-Benz Limited Warranty.
Check regularly and before a long trip, see page 215.

Clearing the service indicator
The service indicator is automatically
cleared after ten seconds when you switch
on the ignition or when reaching the ser-
vice threshold while driving. You can also
clear it yourself.

on your driving habits. A gentle driving
style, moderate engine speeds and the
avoidance of short-distance trips will
lengthen the interval between services.

Left rear rpm sensor (L6/3) (model 168)

Right front rpm sensor (L6/2) (model 208, 210)
Left front rpm sensor (L6/1) and right front rpm sensor (L6/2) (models 203, 209)
The evaluation of the wheel speed signals reveals the mileage covered.
The wheel speed signals of the not driven wheels are evaluated, since their slip between the roadway and tire
is lower, which results in a more accurate result when calculating the mileage.
Calculation of the vehicle orientation
The navigation computer calculates the direction in which the vehicle is traveling (compass direction) from the
data from the gyrosensor and the sequence of locations calculated with the aid of the global positioning system
(GPS). The difference in the calculated mileage and the mileage actually covered between 2 turn-off points is
used to automatically recalibrate the tire circumference (necessary due to tire wear).
Calculation of the direction of motion
The navigation processor recognizes the direction of motion (forward or reverse) from the reverse signal.
Calibration of tire circumference
As a matter of principle, the navigation system recalibrates itself while driving as described. However, this may
require driving a longer distance. After changing tires, manual recalibration should therefore be accomplished.
To do this, it is necessary to enter the tire size (e.g.:195/050/015)and possibly the following information:
new tires (tread depth > approx. 5 mm)
used tires (tread depth < approx. 5 mm)
The entry can be done two different ways:
With aid of STAR DIAGNOSIS.
By calling the "Navigation --> TIRE" menu at the radio (A2)
Errors due to vehicle movement with switched off ignition lead to an inaccurate basic location finding.
Rolling backwards without the reverse gear engaged is evaluated as forwards motion, and may lead to an error
in the location finding. Rolling with the ignition switched off or vehicle transportation also falsify map
matching.
The errors are, however, corrected automatically after a short time by the navigation processor after
receiving GPS data.
A special calibration drive by driving around a defined test path is not ever required.

If there are malfunctions (e.g. brake linings worn, coolant level too

low, exterior lamp failure etc.) or system faults (anti-lock brake

system faulty, supplemental restraint system faulty) the warning

display with warning information is inserted in place of outside

The warning information is displayed in yellow or red depending on

the fault and a warning tone also sounds.
