accelerate or brake suddenly. You will then
no tb e able to brake, declutch or accelerate
as intended. This could lead to accidents and
injury. G
WARNING
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. This could cause you
to lose control of your vehicle and cause an
accident.
! Warm up the engine quickly. Do not use
the engine's full performance until it has
reached operating temperature.
Only set the automatic transmission to the
respective drive positions when the vehicle
is stationary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery
roads. Otherwise, you could damage the
drive train.
! AMG vehicles: at low engine oil tempera-
tures (below +20 †), the maximum engine
speed is restricted in order to protec tthe
engine. To protect the engine and maintain
smooth engine operation, avoid driving at
full throttle when the engine is cold. Key positions
Key g
To remove the key
1 Power supply for some consumers, such
as the windscreen wipers
2 Ignition (power supply for all consumers)
and drive position
3 To start the engine
If the key is at position 0in the ignition lock
for a longer period, it can no longer be turned
in the ignition lock. The steering is then
locked. To unlock it, remove the key and rein-
sert it into the ignition lock.
The steering wheel is locked when the key is
removed from the ignition lock.
i If the key does not belong to the vehicle
it can still be turned in the ignition lock.
However, the ignition will not be switched
on The engine cannot be started.
KEYLESS-GO General notes
Vehicles with KEYLESS-GO are equipped with
a key featuring an integrated KEYLESS-GO
function and a detachable Start/Stop button.
The Start/Stop button must be inserted into
the ignition lock and the key must be in the
vehicle.
Pressing the Start/Stop button several times
in succession corresponds to the different
key positions in the ignition lock. This is only
the case if you are not depressing the brake
pedal. Driving
153Driving and parking Z

However, using this fuel results in consid-
erably higher petrol consumptio
nand sig-
nificantly reduced engine performance.
Avoid driving at full throttle.
If no fuel othe rthan regular petrol with
91 RON/82.5 MON or a lower grade is per-
manently available, you should have the
vehicle adapted to run on this fuel in a
qualified specialist workshop. Mercedes-
Benz recommends that you use a
Mercedes-Ben zService Centre for this pur-
pose.
C 350 BlueEFFICIENCY and C 350
4MATIC BlueEFFICIENCY !
Only refuel using unleaded, sulphur-free
premium-grade petrol with at least
95 RON/85 MON, which conforms to Euro-
pean standard EN 228 or an equivalent
specification.
You can otherwise impair engine output or
damage the emission control system.
i In some countries, the available petrol
may not be sufficiently low in sulphur. This
fuel can temporarily produce unpleasant
odours, especially on short journeys. As
soon as sulphur-free fuel (sulphur content
<10p pm) is used for refuelling, the odours
are reduced. Diesel (EN 590)
Fuel grade !
When refuelling, only use diesel fuel that
conform stothe European standard EN 590
or is of equivalent quality. You can other-
wise impair engine output or damage the
engine.
! Vehicles with diesel particle filters: in
countries outside the EU, only use low sul-
phur Euro diesel with a sulphurc ontent of
under 50 ppm. Otherwise, the emission
control system could be damaged. !
Vehicles without adiesel particle fil-
ter: in countries where only diesel fuels
with a higher sulphur conten tare available,
the vehicle's oil change intervals are
shorter. More information about intervals
for changing the oil can be obtained from
any Mercedes-Benz Service Centre.
! Only use fuel that complies with the EN
590 European standard .Fuel that does not
comply with EN 590 can lead to increased
wear, engine damage and damag eto 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 380).
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 170
RefuellingDriving and parking

not been adapted to suit the climatic condi-
tions, e.g .diesel fuel fro mwarmer regions.
i Further information about country-spe-
cific fuel properties can be obtained from
oil companies, e.g .atfilling 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 diesel fuel.
Correct dosage and thorough mixing are deci-
sive factors in ensuring improvement in low-
temperature resistance. Avoid excessive dos-
age. Excessive dosage may actually decrease
low-temperature resistance under certain cir-
cumstances. Follow the manufacturer's dos-
ing 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
