2011 MERCEDES-BENZ CLS COUPE fuel

under 50 ppm
.Otherwise, the emission
control syste mcould be damaged.
! Vehicles without adiesel particle fil-
ter: the engine oil should be changed more
frequently in countries in which diesel with
a higher sulphur conten tis available. More
information about intervals for changing
the engine oil can be obtained from any
Mercedes-Benz Service Centre.
! Using fuel that does not conform to Euro-
pean standard EN 590 or German standard
DIN 51628 can lead to increased wear,
engine damage and damage to the exhaust
system.
Do not use the following:
R marine diesel
R heating oil
R bio-diesel
R vegetable oil
R petrol
R paraffin
R kerosene
Do not mix these fuels with diesel fuels and
do not use any special additives. Other-
wise, this can lead to damage to the engine.
This excludes flow improver, see "Low out-
side temperatures".
! Use a filter when adding fuel from a fuel
can. Otherwise, the fuel lines and/or the
diesel injection system could be blocked by
particles from the fuel can.
For further information on "Fuel", see
(Y page 319).
Low outside temperatures Diesel fuel with improved cold flow qualities
is available during the winter months. In
Europe, various climate-dependent low-tem-
perature classes are defined in EN 590. Refu-
elling with diesel fuel which complies with the
climatic specifications of standard EN 590
can help to prevent operating problems. At
exceptionally low temperatures, it is possible that the flow properties of the fuel may be
inadequate. This also applies to fuel that has
not been adapted to suit the climatic condi-
tions, e.g. diesel fuel from warmer regions.
i
Further information about country-spe-
cific fuel properties can be obtained from
oil companies, e.g. at filling stations.
Flow improver Flow improvers can be added to improve the
cold resistance of diesel fuel. The effective-
ness of a flow improver is not guaranteed with
every fuel.
Correct dosage and thorough mixing are deci-
sive factors in ensuring improvement in low-
temperature resistance. Under certain cir-
cumstances, an excessive dosage may
actually decrease low-temperature resist-
ance and should therefore be avoided.F ollow
the manufacturer's dosing instructions.
Mix the additive with the diesel in good time,
before the flow properties of the diesel
become inadequate. Malfunctions can other-
wise only be rectified by heating the entire
fuel system, e.g. by parking the vehicle in a
heated garage.
Observe the information provided by the man-
ufacturer when using a flow improver. Only
use flow improvers that have been tested and
approved by Mercedes-Benz. You can obtain
further information from any Mercedes-Benz
Service Centre. Refuelling

Vehicle level Important safety notes
Your vehicle regulates its height automati-
cally. All-round self-levelling ensures the best
possible suspension and constant ground
clearance, even with a laden vehicle. When
you drive fast, the vehicle is lowered auto-
matically to improve driving safety and to
reduce fuel consumption.
The following vehicle levels are possible:
R
normal
R raised: the vehicle is raised by about 25 mm
when compared with the normal level.
R lowered: the vehicle is lowered by about
10 mm when compared with the normal
level.
The "Normal" and "Raised" vehicle levels can
be set manually.
The "Lowered” vehicle level is set automati-
cally:
R at speeds above 140 km/h
R if you have selected "Comfort tuning"
(Y page 168) and then lock the vehicle
within 60 seconds of the engine being
switched off
R if you have selected "Sports tuning"
(Y page 168) G
Risk of injury
If you have selected "Comfort tuning", the
vehicle will be lowered if you lock it within 60
seconds of the engine being switched off.
