Additives
!
Operation of the engine with fuel addi-
tives added later can cause engine damage.
Therefore, do not mix any fuel additives
with the fuel. This does not include addi-
tives for the removal and prevention of
residue build-up. Petrol must only be
mixed with additives recommended by
smart. Observe the instructions for use in
the product description. For further infor-
mation on recommended additives enquire
at any smart centre.
smart recommends that you use fuel brands
that have additives.
The quality of the fuel available in some
countries may not be sufficient. Residue
could build up in the fuel injection system as
a result. In this case, in consultation with a
smart centre, the petrol may be mixed with the
cleaning additive recommended by smart. You
must observe the notes and mixing ratios
specified on the container.
Fuel consumption information
H
Environmental note
CO
2
(carbon dioxide) is the gas which sci-
entists believe to be principally respon-
sible for global warming (the greenhouse
effect). Your vehicle's CO
2
emissions 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
environmental influences, road condi-
tions or traffic flow
You can minimise your vehicle's CO
2
emis-
sions by driving carefully and having it
serviced regularly.
The vehicle will use more fuel than usual in
the following situations:
R
at very low outside temperatures
R
in urban traffic
R
on short journeys
R
in mountainous terrain
i
Only for certain countries: you can find
the current consumption and emission val-
ues of your vehicle in the COC documents
(EU CERTIFICATE OF CONFORMITY). These
documents are delivered with your vehicle.
The consumption figures were in each case
based on the currently applicable version:
R
for vehicles that comply with or exceed
the EURO 5 standard, in accordance with
Regulation (EC) No. 715/2007
Deviations from these values may occur
under normal operating conditions.
Engine oil
General notes
When handling engine oil, observe the impor-
tant safety notes on service products
(
Y
page 217).
The quality of the engine oil is decisive for
the function and service life of an engine.
After extensive tests, Mercedes-Benz appro-
ves engine oils that correspond to the current
technical standard. Therefore, only use
engine oils approved by Mercedes-Benz.
Further information on tested and approved
engine oils can be obtained from any smart
centre. smart recommends that you have the
oil change carried out at a qualified spe-
cialist workshop.
Mercedes-Benz approval is indicated on the
oil container by the inscription "MB
Approval" and the corresponding designa-
tion, e.g. MB Approval 229.51.
You can call up an overview of approved
engine oils on the Internet at
http://bevo.mercedes-benz.com by entering
the designation, e.g. 229.5.
