WARNING
Do not use petrol to refue lvehicles with adie-
sel engine. Do not mix diesel with petrol. This
would result in damage to the fuel system and
engine, which coul dleadtoav ehiclefire.
! Do not use petrol to refue lvehicles with a
diesel engine. Do not use diesel to refuel
vehicles with apetrol engine. Even small
amounts of the wrong fuel result in damage
to the fuel system and the engine.
! Do not switch on the ignitio nifyou acci-
dentally refue lwith the wrong fuel .Other-
wise ,the fuel will ente rthe fuel lines. Notify
aq ualified specialist workshop and have
the fuel tank and fuel lines drained com-
pletely. Petrol (EN 228, DIN 51626)
Fuel grade !
Only refuel using unleaded premium-
grade petrol with at least
95 RON/85 MON, which conforms to Euro-
pean standard EN 228 or an equivalent
specification.
! Do not use the following:
R E85 (petrol with 85% ethanol)
R E100 (100% ethanol)
R M15 (petrol with 15% methanol)
R M85 (petrol with 85% methanol)
R M100 (100% methanol)
R Diesel
Do not mix these fuels with petrol, and do
not use any additives. Otherwise, this can
lead to damage to the engine. This does not
include additives for the removal and pre-
vention of residue build-up. Only additives
recommended by Mercedes-Ben zmay be
added to petrol. Mor einformatio nabout
recommended additives can be obtained
from any Mercedes-Benz Service Centre. !
Use afilter when adding fuel from afuel
can. The fuel lines and/or the diesel injec-
tion system could otherwise be blocked by
particles from the fuel can.
i If the recommended fuel is not available,
but only as atemporary measure, you may
also use regular unleaded petrol,
91 RON/82.5 MON. This may reduce
engin eperformanc eand increase fuel con-
sumption .Avoid driving at full throttle.
In some countries, the fuel grad eavailable
may not be adequate and coul dcause
deposits to build up. In such cases, and in
consultation with aMercedes-Benz Service
Centre, the petrol may be mixed with the
additive recommende dbyMercedes-Benz
(part number A000989254510). You must
observe the notes and mixing ratios speci-
fied on the container.

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. Refuelling

approved exterior aerial. This ensures:
R optimal mobile phone reception quality in
the vehicle
R mutual influences between the vehicle
electronics and mobile phones are mini-
mised
An exterior aerial has the following advan-
tages:
R it conducts the electromagnetic fields gen-
erated by awireless device to the exterior.
R the field strengt hinthe vehicle interior is
lower than in avehicle that does not have
an exterior aerial.

Inserting the mobile phone X
Open the telephone compartment
(Y page 265).
X Place the mobile phone bracket into the
pre-installed bracket (see the separate
mobile phone bracket installation instruc-
tions).
X Insert the mobile phone into the mobile
phone bracket (see the separate mobile
phone bracket installation instructions). If the mobile phone is inserted in the mobile
phone bracket
,you can speak to the person
you are calling using the hands-free system.
i On some mobile phone brackets, you first
have to connect the mobile phone via Blue-
tooth ®
to am obile phone bracket (see the
separate operating instructions for the
mobile phone bracket).
On these mobile phone brackets, the
mobile phone does not have to be inserted
into the bracket for you to be able to use
the telephone functions. In this case, the
charging function and aerial function are
not available.
Operating the mobile phone You can operate the telephone using the
6

steerin gwheel. You can operate other mobile
phone functions via the on-board computer
(Y page 221).
If you take the key out of the ignition lock, the
mobile phone stays on but you can no longer
use the hands-free system.
If you are making acall and you would like to
take the key out of the ignition lock, first
remove the mobile phone from the bracket.
Otherwise, the call will be ended.

You can fold the pre-installed bracket up to
improve access to the stowage space
beneath it. Dependin gonthe vehicle's equip-
ment,aU SB connection and an AUX-IN con-
nection/Media Interface are fitted in the
stowage compartment (Y page 265).274

nc haracteristics, e.g. handling, vehicle
noise emissions or fuel consumption ,may
otherwise be adversely affected. In addi-
tion, when driving with aload, tyre dimen-
sion variations could cause the tyres to
come into contact with the bodywork and
axle components.T his could result in dam-
age to the tyres or the vehicle.
Mercedes-Ben zaccepts no liability for

Further information about tyres, wheels
and approved combinations can be
obtained from any Mercedes-Ben zService
Centre.
! Retreaded tyres are neither tested nor
recommended by Mercedes-Benz, since
previous damage cannot always be detec-
ted on retreaded tyres. As aresult,
Mercedes-Ben zcannot guarante evehicle
safety if retreade dtyres are fitted. Do not
fit used tyres if you have no information
about their previous usage.
! Large wheels :the lower the section width
for acertain wheel size, the lower the ride
comfort is on poor road surfaces. Roll com-
fort and suspension comfort are reduced
and the risk of damage to the wheels and
tyres as aresult of driving over obstacles
increases.
i You will find atable of tyre pressures on
the inside of your vehicle's fuel filler flap.
For further information on tyre pressure,
see (Y page 321).

Vehicles with MOExtende dtyre sare not
equipped with aTIREFIT kit at the factory.
It is therefore recommende dthat you addi-
tionally equip your vehicle with aTIREFIT kit
if you fit tyre sthat do not feature run-flat
properties ,e.g. winter tyres. ATIREFIT kit
can be obtained fro maMercedes-Benz

You can minimise your vehicle's CO 2emis-

Please bear the following in mind The quality of engine oils is decisive for the
function and service life of an engine. After
extensive tests, Mercedes-Benz approves
engine oils which correspon dtothe current
technical standard.
Therefore, only Mercedes-Benz approved
engine oils may be used in Mercedes-Benz
engines.
Further information on tested and approved
engine oils can be obtained from any
Mercedes-Benz Service Centre. Mercedes-
Benz recommends that you have the oil
change carried out at aMercedes-Benz
Service Centre. Mercedes-Benz approval is
indicated on the oil container by the inscrip-
tion "MB Approval" and the corresponding
designation, e.g. MB Approval 229.51.
