Lo wo utside temperatures
In winter months, diese lfue lw ithani mproved
cold flo wquality is available .InEurope, the
EN 590 standard defines variou sclimate-
dependent temperature categories. Malfunc-
tions can be avoided by refuelling with diesel
fue lthat corresponds to the climati cspecifica-
tions outlined in EN 590. At unusually low out-
sid etemperatures, it is possible that the flow
characteristics of the diese lfue lcould be insuf-
ficient. Accordingly ,diese lfue lfrom warmer
areas may not be suitabl efor operation in colder
climati cconditions.
i Further information on country-specific fuel
properties and fue ltypes with low-tempera-
ture resistance can be obtained from oil com- panies ,e.g. at filling stations. AdBlue
®
Important safety notes AdBlue
®
is aw ater-solubl efluid for the exhaust
ga sa ftertreatment of diese lengines. It is:
R non-toxic
R colourless and odourless
R non-flammable
If yo uopent he AdBlue ®
tank, small amounts of
ammonia vapou rmay be released.
Ammoni avapours have apungent odour and are
particularly irritating to the skin, to mucous
membrane sand to the eyes. You may experi-

freezes at atemperature of approx-
imately -11 †. The vehicle is delivered from the
factory equipped with an AdBlue ®
preheating
system. Winte roperation can thus be guaran-
teed eve nattemperatures below -11 †.
Additives !

in accordance with ISO
22241. Do not us eaddit ivesw ithA dBlue ®
and do not dilute AdBlue ®
with water. This
may destroy the BlueTEC exhaus tgas after-
treatment system.
Purity !
Impurities in AdBlue ®
(e.g .due to othe rser-
vice products, cleaning agents or dust) lead
to:
R increase demission values
R damag etothe catalytic converter
R engine damage
R malfunctions in the BlueTEC ®

the antifreeze .Make sur ethat antifreeze is
not spilled next to the filler neck. Thoroughly clea
nthe antifreeze from components before
starting the engine.
! Only ad

! Always use
asuitabl ecoolant mixture, even
in countries where hig htemperatures prevail.
Otherwise ,the engine cooling system is not
sufficiently protected from corrosion and
overheating.
i Have the coolant regularly replaced at a
qualified specialist workshop and the replace- ment confirmed in the Service Booklet.
Comply with the important safety precautions
for service products whe nhandling coolant
(Y page 371).
The coolant is amixture of water and anti-
freeze/corrosion inhibitor. It is responsible for
the following:
R anti-corrosion protection
R antifreeze protection
R raising the boiling point
If antifreeze/corrosion inhibito rispresent in the
correct concentration, the boiling point of the
coolant during operation will be approximately
130 †.
The antifreeze concentrate/corrosion inhibitor
concentration in the engine cooling system
should:
R be at least 50%. Thi swillp rotect the engine
cooling system against freezing dow nto
approximatel y-37 †.
R not excee d55% (antifreeze protection down
to -45 †). Hea twillo therwise not be dissipa-
ted as effectively.
Mercedes-Benz recommends an antifreeze/
corrosion inhibito rconcentrate in accordance
with MB Specifications for Service Products
310.1.
