at shorter intervals. More information
about the interval for oil change can be
obtained from any qualified specialist
workshop.
Usually you will find information about the
fuel grade on the pump. If you cannot find the
label on the petrol pump, ask the filling sta-
tion staff.
Information on refuelling (
Low outside temperatures
In winter months, diesel fuel with an improved
cold flow quality is available. In Europe, the
EN 590 standard defines various climate-
dependent temperature categories. Malfunc-
tions can be avoided by refuelling with diesel
fuel that corresponds to the climatic specifi-
cations outlined in EN 590. At unusually low
outside temperatures, it is possible that the
flow characteristics of the diesel fuel could be
insufficient. Accordingly, diesel fuel from
warmer areas may not be suitable for opera-
tion in colder climatic conditions.

Further information on country-specific
fuel properties and fuel types with low-tem-
perature resistance can be obtained from
oil companies, e.g. at filling stations.
Fuel consumption information
H Environmental note
CO (carbon dioxide) is the gas which scien-
2
tists believe to be principally responsible for
global warming (the greenhouse effect). Your
vehicle's CO emissions are directly related to
2
fuel consumption and therefore depend on:
efficient use of the fuel by the engine
R
driving style
R
other non-technical factors, such as envi-
R
ronmental influences, road conditions or
traffic flow
You can minimise your vehicle's CO
sions by driving carefully and having it serv-
iced regularly.

Only for certain countries: you can find
the current consumption and emission val-

(EU CERTIFICATE OF CONFORMITY). These
documents are delivered with your vehicle.
The consumption figures were, in each

up to and including the EURO 4 standard,
in accordance with EU Directive

Deviations from these values may occur
under normal operating conditions.

AdBlue
Important safety notes
®
AdBlue is a water-soluble fluid for the
exhaust gas aftertreatment of diesel engines.
It is:
non-toxic
R
colourless and odourless
R
non-flammable
R
If you open the AdBlue
of ammonia vapour may be released.
Ammonia vapours have a pungent odour and
are particularly irritating to the skin, to
mucous membranes and to the eyes. You may
experience a burning sensation in your eyes,
nose and throat. You may also experience
coughing and watery eyes.
