Under no circum stances should engine settings
be changed. In addition, all specific main tenance

Unburned fuel can get into the oil pan. This
causes the engine oil le velto rise. This can

Fill up with fuels with bio-diesel content
of 5% (ULSD) or less, whene ver possi‐

Regular lych eck your engine oil le vel if
yo u use B20 fuels on a regular basis. #
Strictly follow the oil change inter vals

Ifyo u do not plan todrive your vehicle

fuel tank in ad vance wi thULSD fuel. Fo
r more information, consult thega sst ation
st aff. The identification of fuels with bio-diesel

DEF consum ption
Like fuel consum ption, DEF consum ption is highly
dependent upon driving style and operating con‐
ditions. DEF consum ption is usually within a
ra nge of 0 and 10% of the fuel consum ption. If

If yo u operate theve hicle without DEF or with

th eSA E classi fication (viscosity) of the
engine oil added is not suitable for prolonged
low outside temp eratures, it may cause
engine damage.
The temp erature readings of theSA E classi fi‐
cation are al ways based on fresh oil. Engine
oil ages when driving as a result of soot and

Therefore, Mercedes-Benz recommends that you

prescribed SAE classi fication forth is purpose. The viscosity indicates
theflow characteristics of
