Operation
Preparation for operation
At the factory, the engine is filled with 5W30
initial operation oil that complies with Sheet
225.6 of the Mercedes-Benz Specifications
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 for
normal operation. This eliminates the need
for special initial operation oils and the addi-
tional oil change otherwise required.
The extended maintenance intervals can only
be observed if engine oils complying with
Sheet 228.5 of the Mercedes-Benz Specifi-
cations for Service Products are used.

are clean and do not allow water to enter
the tank and thus contaminate the fuel.
Refuelling with AdBlue
®
/DEF
Only use AdBlue
®
/DEF that complies with
DIN 70070/ISO 22241. Do not use any addi-
tives. If AdBlue
®
/DEF comes into contact
with painted or aluminium surfaces when fill-
ing the tank, rinse the affected surfaces
immediately with plenty of water.
Bleeding the fuel system
The bleeding of a fuel system that has been
run dry takes place when the engine is next
started after refuelling. Automatic continuous
bleeding takes place in the filter.
i The battery must be sufficiently charged
when the engine is started in order for the
fuel system to be bled.
