Do not use petrol to refuel vehicles with a
diesel engine. Do not use diesel to refuel
vehicles with apetrol engine. Even small
amounts of the wron gfuel result in damage
to the fuel system and the engine.

Notes on fuel consumption The vehicle will use more fuel than usua
lin
the follow ings ituations:
R at very low outside temperatures
R in urban traffic
R on short journeys
R when towing atrailer
R in mountainou sterrain
i Only for certain countries: you can find
the curren tconsumption and emission val-
ues of your vehicle in the COC documents (EU CERTIFICATE OF CONFORMITY). These
documents ar
edelivered with your vehicle.
The consumption figures were in each case
based on the currently applicable version:
R for vehicles up to and including the EURO
4s tandard ,inaccordanc ewithEUD irec-
tive 80/1268/ECC
R for vehicles above the EURO 5standard,
in accordance with Regulatio n(EC) No.
715/2007
Deviations from these value smay occur
under normal operating conditions.
! Do not use any fuel additives, as they can
cause malfunctions and engine damage. H
Environmental note
CO 2(carbon dioxide) is the gas which scien-
tists believe to be principally responsibl efor
global warmin g(the greenhouse effect). Your
vehicle's CO 2emissions are directly related
to fuel consumptio nand therefore depend on:
R efficient use of the fuel by the engine
R driving style
R othe rnon-technical factors, such as envi-
ronmental influences or road conditions
You can minimise your vehicle' sCO
2emis-
sions by driving carefull yand having it serv-
iced regularly. AdBlue

Important safety notes i
For BlueTEC vehicles only.
AdBlue ®
is an on-flammable, non-toxic, col-
ourless, odourless and water-soluble fluid.
! Surfaces which have com einto contact

rinsed immediately with water ,orremove
AdBlue ®
with amoist clot hand cold water.
If AdBlue ®

WARNING
Ammonia vapours may escape if the

skin, to mucous membranes and to the eyes.
You may experienc eaburning sensation in

e.g. during repair work, do not use this fluid to refill the tank
.The purity of the fluid can no

Engine oil
Th
eq uality of engine oils is decisive for the
function and service life of an engine. After
extensive tests, Mercedes-Benz approves
engine oils that correspond to the current
technical standard.
Therefore, only Mercedes-Benz approved
engine oils may be used in Mercedes-Benz
engines.
Further information on tested and approved
engine oils can be obtained from any
Mercedes-Benz Service Centre. Mercedes-
Benz recommends that you have the oil
change carried out at aMercedes-Benz
Ser vice Centre. Mercedes-Ben zapproval is
indicated on the oil container by the inscrip-
tion "MB Approval" and the cor respondi ng
designation, e.g. MB Approval 22 9.51.
Th et able shows which engine oils have been
approved for your vehicle. Petrol engines MB Approval

Additives
!
Do not use additive sinengine oil .This
could damage the engine.
Engine oil viscosity Viscosit
ydescribes the flow characteristi cs
of afluid. If an engin eoil has ahigh viscosity
rating, it flows slowly; the lower the viscosity,
the faster it flows.
Engine oil selection is based on the respective
outside temperatures and in accordance with
the SA Eclassification (viscosity). The table
below shows you which SA Eclassifications are to be used. The low-temperature proper-
ties of engin eoils can be significantly
impaired durin goperation due to, for exam-
ple, ageing or soot and fuel accretion. It is
therefore strongly recommende dtoobserve
regula roil changes using an approved engine
oil with the appropriate SA Eclassification. Brake fluid
G
WAR
NING
Over aperiod of time, the brak efluid absorbs
moisture fro mthe air ;This lower sits boiling
point.
If the boiling point of the brake fluid is too low,
vapour pockets may form in the brake system
when the brakes are applied hard (e.g. when
driving downhill). Thi simpairs brakin geffi-
ciency.
Yo us hould hav ethe brake fluid renewed at
regular intervals. The brake fluid change inter-
vals can be found in the Servic eBooklet.
Only use brak efluid approved by Mercedes-
Benz .Information abou tapproved brak eflu-
ids can be obtained from any Mercedes-Benz

Coolant
Important safety notes The coolan
tisamixture of water and anti-
freeze/corrosio ninhibitor. It performs the
following tasks:
R anti-corrosio nprotection
R antifreeze protection
R raising th eboiling point
i When the vehicle is first delivered, it is fil-
led with acoolant mixtur ethat ensures
adequate antifreeze and corrosion protec-
tion.
! Only add coolant that has been premixed
with the desired antifreeze protection. The
engin ecould otherwise be damaged.
Further information on coolants and on fill-
ing can be found in the Mercedes-Benz
Specifications for Servic eProducts ,MB
Approval 310.1 ,e.g. on the Internet at
http ://bevo.mercedes-benz.com .You can
also consult aMercedes-Benz Service
Centre.
! Alway suseasuitable coolant mixture,
even in countries where high temperatures
prevail.
Otherwise, the engine cooling system is not
sufficiently protected from corrosion and
overheating.
If antifreeze/corrosio ninhibitor is present in
the correc tconcentration, the boilin gpoint of
the coolant during operation will be around
13 0†.
The antifreeze/ corrosion inhibitor con centra-
tion in the engine cooling system should:
R be at leas t50%. This wil lprotect the engine
coolin gsystem agains tfreezin gdown to
around -3 7†.
R not excee d55% (antifreeze protection
down to -45 †);otherwise, heat will not be
dissipated as effectively.
If the vehicle has los tcoolant, top it up with
equal amount sofwater and antifreeze/cor- rosion inhibitor. Mercedes-Benz recom-
mends an antifreeze/corrosion inhibitor
which has been approved for Mercedes-Benz.
! The engin ecoolin gsystem is filled with
coolant that must be renewed after 15
years, or after 250,000 km at the lates t. Vehicl
