2009 MERCEDES-BENZ E-CLASS COUPE engine

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 add such fuels to diesel fuel and do
not use any special additives (exception:
flow improvers –see "Low outside temper-
atures").
Damage caused by the use of unapproved
fuels or additives is not covered by the
implied warranty.
Further information on "Fuel" (Y page 287).
Low outside temperatures The flow properties of diesel may be inade-
quate at low ambient temperatures.
Diesel fuel with improved cold flow qualities
is available during the winter months. In
Europe, the different climate-dependant cold
categories are defined in standard EN 590.
Refuelling with diesel fuel which complies
with the climatic specifications of standard
EN 590 can help to prevent operating prob-
lems. If the ambient temperature is unusually
low or if you use fuel that has not been adap-
ted to the climatic specifications (e.g. diesel
fuel from the Mediterranean area), the flow
properties of the fuel may be inadequate.
Flow improver
Flow improvers can be added to improve the
cold resistance of diesel fuel. The effective-
ness of aflow 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 (follow
the manufacturer's dosing instructions).
Mix the additive with the diesel in good time,
before the flow properties of the diesel
become inadequate. Otherwise, malfunctions
can only be rectified by heating the entire fuel
system, e.g. by parking the vehicle in
aheated
garage.
Observe the information provided by the man-
ufacturer when using aflow improver. Only
use flow improvers that have been tested and
approved by Mercedes-Benz.Y ou can obtain
further information from any Mercedes-Benz
Service Centre. Enginec

G
Risk of accident
Do not pull the release lever while the vehicle
is in motion. If you do so, the bonnet may open
up and block your view.
Active bonnet( pedestrian protection) The active bonnet can reduce the risk of injury
to pedestrians in certain accident situations.
Raising the bonnet increases the clearance to
hard components, such as the engine. Fur-
ther information aboutt

Risk of injury
There is arisk of injury if the bonnet is open,
even if the engine is not running.
Some engine componentsc an become very
hot.
To avoid the risk of burns, only touch those
componentsd escribed in the Owner's Manual
and observe the relevant safety notes. 180

Depending on driving style, the vehicle con-
sumes up to 0.8 loil per 1,000 km. The oil
consumption may be highert han this when
the vehicle is new or if you frequently drive at
high engine speeds.
Checking the engine oil level Before checking the engine oil level the fol-
lowing conditions for the vehicle shouldbe
met:
R
the vehicle shouldbep arked on level
ground.
R the engine shouldbes witched off for at
least five minutes if the engine is at normal
operating temperature.
R the engine shouldbes witched off for at
least 30 minutes if the engine is not at
operating temperature (i.e. if you only start
the engine briefly).
Depending on the engine, the oil dipstick may
be installed at adifferent location. E3

Pullo il dipstick 0046out of the oil dipstick
tube.
X Wipe off oil dipstick 0046.
X Insert oil dipstick 0046into the oil dipstick
tube to the stop, and take it out again.
The oil level is correct if the level is between
the minimum mark 008Aand maximum
mark 0047.
X Top up the oil if necessary.
Topping up the engine oil H
Environmental note
When topping up the oil, take care not to spill
any. Oil must not be allowed to escape into
the soil or waterways. You would otherwis ebe
damaging the environment. Cap (example)
X Turn cap 0046anti-clockwise and remove.
X Top up with the amount of oil required

approximately 2litres.
i On vehicle switha4-cylinder petrol
engine and vehicle swith an 8-cylinder pet-
rol engine, the difference betwee nthe MIN
mark and the MAX mark is approximately
1.5 litres.

Once you have fitted the winter tyres:
X
Check the tyre pressures (Y page 186).
X Restart the tyre pressure loss warning sys-
tem (Y page 187). G
Risk of accident
If you fit the spare wheel* when driving with
winter tyres, bear in mind that driving stability
will be impaired owing to unstable cornering
characteristics caused by the different tyres.
You should therefore adapty our driving style
and drive carefully.
Have the spare wheel* replaced at the near-
est qualified specialist workshop which has
the necessary specialist knowledge and tools
to carry out the work required. Mercedes-
Benz recommends that you use aMercedes-
Benz Service Centre for this purpose. In par-
ticular, work relevant to safety or on safety-
related systems must be carried out at aquali-
fied specialist workshop. Snow chains
For safety reasons, Mercedes-Benz recom-
mends that you only use snow chains which
have been speciallya pproved for your vehicle
by Mercedes-Benz,ora re ofacorresponding
standard of quality.
If you intend to fit snow chains, pleaseb ear
the following points in mind:
R you may not attach snow chains to all
wheel-tyre combinations; see the "Tyres
and wheels" section in the "Technical data"
chapter.
R snow chains must not be fitted to emer-
gency spare wheels, e.g. a"Minispare"
emergency spare wheel.
R Fit snow chains only in pairs and only to the
rear wheels. Comply with the manufactur-
er's installation instructions.
Do not exceed the maximum permissible
speed of 50 km/h.
i You may wish to deactivate ESP ®
when
pulling awayw ith snow chains fitted (Y
page 54). This way,y ou can allowthe
wheels to spin in acontrolled manner, ach-
ieving an increased driving force (cutting
action). Winter driving
G
Risk of accident
Do not shift down for additional engine brak-
ing on aslippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid.
You should drive particularly carefully on slip-
pery road surfaces. Avoid sudden accelera-
tion, steering and braking manoeuvres.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
X Vehicles with manual transmission: engage
neutral.
X Vehicles with automatic transmission*:
shift the selector lever to N.
X Try to bring the vehicle under control by
using corrective steering. Driving tips
Rolling with the engines
witchedoff G
Risk of accident
Never switch the engine off while the vehicle
is in motion.
There is no power assistance for the steering
and the service brake when the engine is not
running.
You will require considerably more effort to
steer and brake and you could therefore lose
control of the vehicle and cause an accident. 190
