MTU 4R 1000 SERIES, Operating Instructions Manual

Preparation for operation
Engine with initial operation oil from
the factory
The engine is filled at the factory with an initial
operation oil.
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 break-in oils
and the additional oil change otherwise
required.
Checking the engine oil level
The engine is equipped with an electronic oil
level detection system.
If the engine is also equipped with a dipstick,
this is subsidiary to the electronic oil level
measurement system. It 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 man-
agement control module (MCM) and trans-
mitted to the drive control system control unit
(ADM) via the engine CAN.
Output can be displayed on a matrix display
when the engine is not running.
Checking the oil level electronically
Check the engine oil level on a regular basis,
e.g. before each journey or each time you
refuel.
Make sure that you also observe the notes in
the vehicle/device manufacturer's operating
instructions.
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

Wait approximately five to ten minutes. If

for the engine and which meets the specified
SAE classification (
Y
page 53).
Checking the oil level with the dipstick
!
Do not add too much oil. If you add too
much oil, the engine or the exhaust after-
treatment unit could be damaged. Drain or
siphon off any excess oil.
Check the engine oil level on a regular basis,
e.g. before each journey or each time you
refuel.
