! Refuel using only unleaded, sulphur-free
premium grade petrol with a minimum
octane number of 95 RON/85 MON con-
forming to European standard EN 228.
Otherwise, you could impair engine output
or damage the engine.
i As a temporary measure, only when the
recommended fuel is not available, you
may also use regular unleaded petrol,
91 RON/82.5 MON. This may reduce
engine performance and increase fuel con-
sumption. Avoid driving at full throttle.
In some countries, the fuel grade available
may not be adequate and could cause cok-
ing around the inlet valve. In such cases,
and in consultation with a Mercedes-Benz
Service Centre, the petrol may be mixed
with the additive recommended by
Mercedes-Benz (part no.
A000989254510). You must observe the
notes and mixing ratios specified on the
container.

soon as sulphur-free fuel (sulphur content
< 10 ppm) is used for refuelling, the odours
are reduced.
AMG vehicles !
Refuel using only unleaded super grade
petrol with a minimum octane number of
98 RON/88 MON conforming to European
standard EN 228.
Otherwise, you could impair engine output
or damage the engine.
i If the recommended fuel is not available
and only as a temporary measure, you may
also use premium unleaded petrol,
95 RON/85 MON. This may reduce engine
performance and increase fuel consump-
tion. You must avoid driving at full throttle.
! In emergencies, and only when the rec-
ommended fuel is not available, you may
also use standard unleaded petrol,
91 RON/82.5 MON.
However, using this fuel results in consid-
erably higher petrol consumption and sig-
nificantly reduced engine output. Avoid
driving at full throttle.
If no fuel other than 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 by the
local after-sales service. Diesel (EN 590, DIN 51628)
G
Risk of fire
Do not use petrol to refuel vehicles with a die-
sel engine. Never mix diesel with petrol. This
causes damage to the fuel system and engine
and could result in the vehicle catching fire.
! Refuel using only diesel which conforms
to European standard EN 590 or German
standard DIN 51628. Otherwise, you could
impair engine output or damage the engine. !
When refuelling vehicles with a diesel par-
ticulate filter in countries outside the EU,
only low-sulphur Euro diesel with less than
0.005 percent sulphur content by weight
(50 ppm) should be used.
! In countries in which diesel with a higher
sulphur content is available, the engine oil
should be renewed at more frequent inter-
vals. More information about intervals for
changing the engine oil can be obtained
from any Mercedes-Benz Service Centre.
! Using fuel that does not comply with the
European standard EN 590 or the 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 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 334).
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.

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 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 (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 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. Engine compartment
Bonnet
G
Risk of accident
Do not pull the release lever while the vehicle
is in motion. The bonnet may otherwise open
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 about the active bonnet
(Y
page 302).

Risk of injury
There is a risk of injury if the bonnet is open,
even if the engine is not running.
Some engine components can become very
hot.
To avoid the risk of burns, only touch those
components described in the Operating
Instructions and observe the relevant safety
notes. G
Risk of injury
The radiator fan between the radiator and the
engine can start automatically, even if the key
has been removed from the ignition lock.
Keep away from the area of rotation of the fan
blades. Otherwise you could be injured.
Vehicles with a petrol engine:
The electronic ignition system uses high volt-
age. For this reason, you must never touch the
ignition system components (ignition coil,
ignition cable, spark plug connector or test
socket) while:
R the engine is running
R the engine is being started
R the ignition is switched on and the engine
is being cranked by hand
You could otherwise receive an electric shock
and be severely or fatally injured.
Vehicles with a diesel engine:
the electronic injector control operates at
high voltage. For this reason, you must never
touch injection system components while:
R the engine is running
R the engine is being started
R the ignition is switched on

Risk of injury
Make sure that nobody can become trapped
as you close the bonnet.
X Lower the bonnet and let it fall from a
height of approximately 20 cm.
X Check that the bonnet has engaged prop-
erly.
i If the bonnet can be raised slightly, it is
not properly engaged. Open it again and
close it with a little more force. Engine oil
Depending on driving style, the vehicle con-
sumes up to 0.8 l oil per 1,000 km. The oil
consumption may be higher than 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 should be
met:
R the vehicle should be parked on level
ground.
R the engine should be switched off for at
least five minutes if the engine is at normal
operating temperature.
R the engine should be switched 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 a different location. 220

Tyres and wheels
Points to remember
! For safety reasons, Mercedes-Benz rec-
ommends that you only use tyres, wheels
and accessories which have been approved
by Mercedes-Benz specifically for your
vehicle. These tyres have been specially
adapted for use with the control systems,
such as ABS or ESP ®
, and are marked as
follows:
R MO = Mercedes-Benz Original
R MOE = Mercedes-Benz Original Exten-
ded* (tyres with run-flat characteristics)
R MO1 = Mercedes-Benz Original (only
specific AMG tyres)
Only use Mercedes-Benz Original Extended
tyres* on wheels that have been specifi-
cally approved by Mercedes-Benz.
If you use other tyres, wheels and acces-
sories, Mercedes-Benz cannot accept any
responsibility for damage that may result
from this. Further information about tyres,
wheels and approved combinations can be
obtained from any Mercedes-Benz Service
Centre.
! If you fit tyres other than those tested and
recommended by Mercedes-Benz, charac-
teristics such as handling, noise levels and
fuel consumption, etc. may be adversely
affected. In addition, when driving with a
load, tyre dimensional variations could
cause the tyres to come into contact with
the bodywork and axle components. This
could result in damage to the tyres or the
vehicle.
! Retreaded tyres are neither tested nor
recommended by Mercedes-Benz, since
previous damage cannot always be detec-
ted on retreaded tyres. As a result,
Mercedes-Benz cannot guarantee vehicle
safety if retreaded tyres are fitted. Do not
fit used tyres if you have no information
about their previous usage. G
Risk of accident
Tyres, wheels or accessories which have not
been approved by Mercedes-Benz for your
vehicle or are not used as they should be, can
impair driving safety. As a result, you could
cause an accident. Before purchasing and
using them, enquire about their suitability,
legal stipulations and factory recommenda-
tions at a Mercedes-Benz Service Centre.
Modification work on the brake system and
wheels is not permitted, nor is the use of
spacer plates or brake dust shields. This inva-
lidates the General Operating Permit for the
vehicle.
Notes on selecting, fitting and replac-
ing tyres R
Only fit tyres and wheels of the same type
and make.
R Only fit tyres of the correct size onto the
wheels.
R After fitting new tyres, run them in at mod-
erate speeds for the first 100 km as they
only reach their full performance after this
distance.
R Fit new tyres on the front wheels first if
tyres of the same size are required on the
front and rear wheels.
R Replace the tyres after six years at the lat-
est, regardless of wear. This also applies to
the spare wheel*.
R Do not drive with tyres which have too little
tread depth, as this significantly reduces
the traction on wet roads (aquaplaning).
! Store tyres that are not being used in a
cool, dry and preferably dark place. Protect
the tyres against oil, grease, petrol and die-
sel.
Notes on regularly inspecting wheels
and tyres R
Regularly check the wheels and tyres of
your vehicle for damage (e.g. cuts, punctu- Tyres and

res, tears, bulges on tyres and deformation,
cracks or severe corrosion on wheels), at
least every 14 days, as well as after driving
off-road or on rough roads. Damaged
wheels can cause a loss of tyre pressure.
R Regularly check the tyre tread depth and
the condition of the tread across the whole
width of the tyre (Y page 224). If neces-
sary, turn the front wheels to full lock in
order to inspect the inner side of the tyre
surface.
R All wheels must have a valve cap to protect
the valve against dirt and moisture. Do not
fit anything onto the valve (such as tyre
pressure monitoring systems) other than
the standard valve cap or other valve caps
approved by Mercedes-Benz for your vehi-
cle.
R Regularly check the pressure of all the tyres
including the spare tyre*, particularly prior
to long trips, and correct the pressure as
necessary.
Notes on driving R
While driving, pay attention to vibrations,
noises and unusual handling characteris-
tics, e.g. pulling to one side. This may indi-
cate that the wheels or tyres are damaged.
If you suspect that a tyre is defective,
reduce your speed and stop the vehicle as
soon as possible to check the wheels and
tyres for damage. Hidden tyre damage
could also be causing the unusual handling
characteristics. If you find no signs of dam-
age, have the wheels and tyres examined
at a specialist workshop, for example at a
Mercedes-Benz Service Centre.
R When parking your vehicle, make sure that
the tyres do not get deformed by the kerb
or other obstacles. If it is necessary to drive
over kerbs, speed humps or similar eleva-
tions, try to do so slowly and at an obtuse
angle. Otherwise, the tyres, particularly the
sidewalls, can get damaged. Direction of rotation
Tyres with a specified direction of rotation
have additional benefits, e.g. if there is a risk
of aquaplaning. You will only gain these ben-
efits if the correct direction of rotation is
observed.
An arrow on the sidewall of the tyre indicates
its correct direction of rotation. MOExtended run-flat system*
The MOExtended run-flat system allows you
to continue driving the vehicle even when one
or more tyres lose all air pressure.
The MOExtended run-flat system may only be
used in conjunction with the tyre pressure
loss warning system or with the tyre pressure
monitor* and on wheels specifically tested by
Mercedes-Benz.
i Vehicles with the MOExtended run-flat
system are not equipped with the TIREFIT
kit. 38
It is therefore recommended to additionally
equip your vehicle with the TIREFIT kit when
fitting tyres that do not feature run-flat
properties, e.g. winter tyres.
i A TIREFIT kit is available from any quali-
fied specialist workshop, e.g. a Mercedes-
Benz Service Centre.
You will find notes on driving with a flat tyre
in the "Practical advice" section
(Y page 318). Tyre tread
