Maintenance
Calling up the service indicator
Switch ignition on.
The standard display of the control sys-

on the mul-
tifunction steering wheel until the FSS
indicator appears in the multifunction
display.
Resetting the service indicator
In the event that the service on your vehi-
cle is not carried out by an authorized
Mercedes-Benz Light Truck Center, you
can reset the service indicator yourself.
Switch ignition on.
The standard display of the control sys-
tem appears (
page 111).

Press button
k
or
j
on the mul-
tifunction steering wheel until the FSS
indicator appears in the multifunction
display.

Press the reset knob (
page 230) for
about four seconds.
This message appears in the tachome-
ter:
DO YOU WANT TO RESET SERVICE INTER-
VAL? CONFIRM BY PRESSING R

To confirm, hold down the reset knob
(page 230) until you hear a signal.
The service indicator now displays the
reset interval.
iIf the vehicle battery is disconnected,
the days of disconnection will not be in-
cluded in the count shown by the ser-
vice indicator. To arrive at the true
service deadline, you will need to sub-
tract these days from the days shown
in the service indicator.
Do not confuse the service indicator
with the engine oil level indicator
:
.
iIf the service indicator was inadvertent-
ly reset, have a Mercedes-Benz Light
Truck Center correct it.
Only reset if the proper service has
been performed. Resetting the system
without performing proper service as
called for by the FSS will cause the FSS
to incorrectly determine the next ser-
vice interval which will result in engine
damage not covered by the Mer-
cedes-Benz Limited Warranty.

Carefully bring the vehicle to a
halt as soon as possible.

Turn off the engine.

Add engine oil and check the
engine oil level (

CHECK LEVEL!
The engine oil level is too low.
See also comments on the following

Check the engine oil level
(page 218) and add oil as re-
quired.

ENGINE OIL LEVEL
REDUCE OIL LEVEL!
You have added too much engine oil.
There is a risk of damaging the en-

255 Practical hints
What to do if …
When the ENGINE OIL LEVEL – CHECK
LEVEL! message appears while the engine
is running and at operating temperature,
the engine oil level has dropped to approx-
imately the minimum mark on the dipstick.
When this occurs, the warning will first
come on intermittently and then stay on if
the oil level drops further.If no oil leaks are noted, continue to drive
to the nearest service station where the
engine oil should be topped to the “full”
mark on the dipstick with an approved oil.:
ENGINE OIL
VISIT WORKSHOP!
The engine oil has dropped to a crit-
ical level.

Check the engine oil level
(page 218) and add oil as re-
quired.

If you must add engine oil fre-
quently, have the engine
checked for possible leaks.

There is water in the oil.

Have the oil checked.

319 Technical data
Fuels, coolants, lubricants etc.
Gasoline additives
A major concern among engine manufac-
turers is carbon build-up caused by gaso-
line. Mercedes-Benz recommends only the
use of quality gasoline containing additives
that prevent the build up of carbon depos-
its.
After an extended period of using fuels
without such additives, carbon deposits
can build up especially on the intake valves
and in the combustion area, leading to en-
gine performance problems such as:

Warm-up hesitation


Unstable idle


Knocking/pinging


Misfire


Power loss
Do not blend other specific fuel additives
with fuel. This only results in unnecessary
cost and may be harmful to the engine op-
eration.Damage or malfunctions resulting from
poor fuel quality or from blending specific
fuel additives are not covered by the
Mercedes-Benz Limited Warranty.
Coolants
The engine coolant is a mixture of water
and anticorrosion / antifreeze, which pro-
vides:

Corrosion protection


Freeze protection


Boiling protection (by increasing the
boiling point)
The cooling system was filled at the factory
with a coolant providing freeze protection
to approximately -35°F (-37°C) and corro-
sion protection.
If the antifreeze mixture is effective to
-22°F (-30°C), the boiling point of the cool-
ant in the pressurized cooling system is
reached at approximately 266°F (130°C).The coolant solution must be used year
round to provide the necessary corrosion
protection and increase in the boil-over
protection. You should have it replaced
every 3 years.
To provide important corrosion protection,
the solution must be at least 45% anticor-
rosion/antifreeze (equivalent to freeze
protection to approx. - 22°F [-30°C]).
If you use a solution that is more than 55%
anticorrosion/antifreeze (freeze protec-
tion to approx. - 49°F [-45°C]), the engine
temperature will increase due to the lower
heat transfer capability of the solution.
Therefore, do not use more than this
amount of anticorrosion/antifreeze.
If the coolant level is low, water and MB
anticorrosion /antifreeze should be used
to bring it up to the proper level (have cool-
ing system checked for signs of leakage).
Please make sure that the mixture is in ac-
cordance with label instructions.
The water in the cooling system must meet
minimum requirements, which are usually
satisfied by normal drinking water. If you
