Do not use petrol to refuel vehicles with a
diesel engine. Do not use diesel to refuel
vehicles with a petrol engine. Even small
amounts of the wrong fuel result in damage
to the fuel system and the engine.
Further information on refuelling and on fuels
(Y page 142).
Notes on fuel consumption The vehicle will use more fuel than usual in
the following situations:
R at very low temperatures
R in urban traffic
R on short trips
R in mountainous terrain
i Only for certain countries: the respective
current consumption and emission values
of your vehicle can be found in the COC
papers (EC CERTIFICATE OF CONFORM-
ITY). These documents are supplied when
the vehicle is delivered.
The consumption figures for vehicles up to
the EURO 4standard have been deter-
mined in accordance with EU Directive
80/1268/EEC while figures for vehicles
complying with the EURO 5standard or
higher have been determined in accord-
ance with Regulation (EC) No. 715/2007,
in each case based on the currently appli- cable version. Deviations fro
mthese values
may occur under normal operating condi-
tions.
! 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 responsible for
global warming (the greenhouse effect). Your
vehicle's CO 2emissions are directly related to
fuel consumption and therefore depend on:
R efficient use of the fuel by the engine
R driving style
R other non-technical factors, such as envi-
ronmental influences or road conditions
You can minimise your vehicle's CO 2emis-
sions by driving carefully and having it serv-
iced regularly. Engine oil
Please bear the following in mind The quality of engine oils is decisive for the
function and service life of an engine. After
extensive tests, Mercedes-Ben zapproves
engine oils which 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-
Ben zrecommends that you have the oil
change carried out at a Mercedes-Benz
Service Centre. Mercedes-Benza pproval is
indicated on the oil container by the inscrip-
tion "MB Approval" and the corresponding
designation, e.g. MB Approval 229.51.
The table shows which engines oil have been
approved for your vehicle.

Additives
!
Do not use additives in engine oil. This
could damage the engine.
Engine oil viscosity Viscosity describes the flow characteristics
of a fluid. If an engine oil has a high viscosity,
this means that it is thick; a low viscosity
means that it is thin.
Engine oil selection is based on the respective
outside temperatures and in accordance with
the SAE classification (viscosity). The table
below shows you which SAE classifications
are to be used. The low-temperature proper-
ties of engine oils can be significantly
impaired during operation due to, for exam-
ple, ageing or soot and fuel accretion. It is
therefore strongly recommended to observe
regular oil changes using an approved engine
oil with the appropriate SAE classification.
