vethefo llowing when storing wheels:
R Wheels that ha vebeen remo ved should be
st ored in a cool, dry and, if possible, dark
place.
R Protect the tires from oil, grease and fuel. Overview of
the tire-chan getool kit Necessary tire-changing
tools may include, for

clogging. Deposits may also
form onthe fuel
injec tor.This may reduce the engine output.
Unburned fuel can get into the oil pan. This
causes the engine oil le velto rise. This can
cause engine mechanical damage.
Obser vethefo llowing points to avoid damage
and reducing the engine output: #
Fill up with fuels with bio-diesel content
of 5% (ULSD) or less, whene ver possi‐
ble. #
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
qu oted in the instrument clus ter and
within your Main tenance Bookl et. #
Use only engine oils and filters
appr ovedfo r use in your vehicle. #
Ifyo u do not plan todrive your vehicle
fo r se veralwe eks, comple tely fill the
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
con tent (ULSD or B20) must be clear. If the iden‐
tification is not clear, do not refuel. Do not refuel
with any fuels that ha venot been appr ovedfor
yo ur vehicle.

DEF consum ption and filling capacity
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
necessar y,DEF mu stbe refilled in acco rdance
with the instructions when there fill message is
displa yed in the instrument clus ter.This may also
be necessary between the scheduled mainte‐
nance.

The vehicle must be operated with DEF if the

If yo u operate theve hicle without DEF or with
emissions-rele vant malfunctions, the legal MOT

It may be improper or punishable in some coun‐

Engine management monitors theex haust gas
af te rtre atment components for compliance with
emissions la wsand regulations. If you attem ptto
operate theve hicle without DEF, with diluted DEF
or with a dif fere nt reducing agent, this will be
de tected bythe engine management sy stem.
Other emissions- releva nt malfunctions, e.g.
me tering malfunctions or sensor er rors, are also

TEEngine damage due toincor rect
SA E classi fication (viscosity) of the
engine oil If
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
fuel residue. The characteristics of engine oil
de teriorate significantly at low outside tem‐
peratures. #
Use an engine oil of the appropriate SAE
classi fication at low outside temp era‐
tures. #
Use oil for all-year-round operation. The
temp erature readings of theSA E classi fica‐
tion are al ways based on fresh oil. The temp era‐
ture characteristics of the engine oil, especially at
low outside temp eratures, can de teriorate signifi‐
cantly due toaging when driving.
Therefore, Mercedes-Benz recommends that you
ch ange the engine oil before thest art of the cold
season. Only use an appr oved engine oil in the
prescribed SAE classi fication forth is purpose. The viscosity indicates
theflow characteristics of
a fluid. With rega rd toengine oil, a high viscosity
is synonymous with thick liquid and a low viscos‐
ity with thin liquid. Depending on the outside
te mp eratures, select the engine oil according to
th eSA E classi fication (viscosity). The table sho ws
th eSA E classi fications tobe used. The low tem‐
perature characteristics of engine oils can de teri‐
orate significantly during operation due toaging
and soot and fuel acc retion, forex ample. A regu‐
lar oil change with an appr oved engine oil in the
appropriate SAE classi fication is therefore
stro ngly recommended. Te
