Quality and capacity of engine oil
%
The containers of
theva rious engine oils are
mar ked with theAC EA (Association of Euro‐
pean Automotive Manufacturers) and/or API
(America Petroleum Institu te) classifications.
Only use appr oved engine oils that cor re‐
spond tothe MB Specifications for operating
fl uids and the prescribed ACEA and/or API
classi fications named bel ow. Engine oils of
ot her grades are not permissible and can
re sult in the loss of the New Vehicle Limited
Wa rrant y.The use of other engine oils not
appr ovedfo r diesel engines can dama gethe
diesel particulate filter (DPF).

Re commended for lo west possible fuel con‐
sum ption (lo westSA E viscosity class in ea ch
case; obser vepossible restrictions of the

To achie vethe lo west possible fuel consum ption,
it is recommended touse the engine oil specifica‐
tions mar ked in theta ble forth e lo west SAE vis‐
cosity class. Obser veany possible restrictions of
th e appr ovedSA E viscosity classes.
If th e engine oils lis ted in theta ble are not availa‐
ble, you may add a maximum 1.1 US qt (1.0 liter)
of thefo llowing engine oils once only:
R Vehicles with a gasoline engine: MB-Frei‐
ga be or MB-Appr oval 229.3 or ACEA A3/B4
R Vehicles with a diesel engine: MB-Freigabe
or MB-Appr oval 228.5, 229.3 or 229.5
Multig rade engine oils of the prescribed SAE clas‐
si fication (viscosity) may be used all year round,
ta king the outside temp erature into account. Vi

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

TEEngine damage due touse of addi‐
tives in the engine oil The use of additional additives in
the engine
oil can damage the engine. #
Do not use any additional additives in
the engine oil. Miscibility of engine oil
The benefits of high-quality engine oils are
re
duced bymixing oil.
We recommend that you on lyuse engine oil of
th e same grade and SAE classi fication as the oil
fi lled at the last oil change. If, in exceptional
cases, engine oil of the type in the engine is not
av ailable, use ano ther appr oved mineral or syn‐
th etic engine oil.
Ve hicles with a diesel engine: ifth e grade is
not available, you may also refill with engine oils
acco rding toMB-F reigabe or MB-Appr oval 228.5,
229.3 or 229.5. The refill qu antity is then limited
to maximum 1.1 US qt (1.0 liter).
Yo u must then ha vean oil change car ried out at
th e earliest possible opportunit y.
Ve hicles with a gasoline engine: ifth e grade is
not available, you may refill with engine oils
acco rding toMB-F reigabe or MB-Appr oval 229.3
or AC EA A3/B4. The refill qu antity is then limited
to maximum 1.1 US qt (1.0 liter).
Yo u must then ha vean oil change car ried out at

Depending on the driving style, theve hicle con‐
sumes a maximum of 1.1 US qt (1.0 liter) of
engine oil per 620 miles (1000 km).
In thefo llowing cases, oil consum ption may also
exc eed this limit:
R The vehicle is ne w.
R You use theve hicle mostly under arduous
conditions.
R You drive frequent lyat a high engine speed.
Re gular maintenance is a prerequisite forfa vo ra‐
ble consum ption figures. You can only assess the
oil consum ption af ter a long journe y.Check the
oil le vel in the engine regularly, e.g. weekly or
eve rytime youre fuel. Note

WARNING Risk of an accident due to
va por poc kets form ing in the brake sys‐
tem
The brake fluid con stant lyabsorbs moisture
from the air. This lo wersthe boiling point of
th e brake fluid. If the boiling point is too lo w,
va por poc kets may form inthe brake sy stem
when the brakes are applied hard.
This causes the braking ef fect to be impaired. #
Have the brake fluid rene we d at the
specified inter vals. *
