Operation
Preparation for daily operation
Engine with initial operation oil from the
factory
The engine is filled at the factory with initial
operation oil that complies with Sheet Num-
ber 225.6 of the Mercedes-Benz Specifica-
tions for Service Products.
These high-quality engine oils are beneficial
to the running-in process. They also allow you
to make the first oil change in accordance
with the applicable oil change intervals. This
eliminates the need for special initial opera-
tion oils and the additional oil change other-
wise required.
The extended maintenance intervals can only
be used if engine oils complying with Sheet
Number 228.5 or 228.51 of the
Mercedes-Benz Specifications for Service
Products are used.
Engine oil level
The engine is equipped with an electronic oil
level detection system. The electronic oil
level measurement system is significantly
more accurate than oil level measurement
using the dipstick.
If the engine is also equipped with a dipstick,
this is subsidiary to the electronic oil level
measurement system and is merely used for
a general check to determine if there is oil in
the engine.
Electronic oil level measurement – sys-
tem description
The engine oil level sensor is installed in the
oil pan for oil level measurement. The electri-
cal signals are detected in the engine control
(MR) control unit and transmitted to the drive
control (FR) control unit via the engine CAN.
Output is in percentage values and can be
displayed on the instrument or on a matrix
display.
Definition of the output values (

page 106).
Checking the oil level electronically
Check the engine oil level on a regular basis,
e.g. every week or each time you refuel.
The current oil level in the engine is only dis-
played once the engine is switched off and
with the ignition switched on. An accurate
display of the engine oil level is therefore only
possible with the engine switched off and the
ignition switched on.
X
Park the vehicle/equipment on a horizontal
surface.
X
Engage the parking brake.
X
Switch off the engine.
X
Wait approximately five to ten minutes. If
you call up the oil level in the engine too
early or while the engine is running, it is not
available.
X
If necessary, use filler neck
:
to top up the
oil.
Only use engine oil which has been approved
for the engine and which meets the specified
SAE classification.
! Do not add too much oil. If you add too
much oil, the engine or the catalytic con-
verter could be damaged. Drain or siphon
off any excess oil.
