fere with the vehicle's electronics and thereby
jeopardise the operating safety of the vehicle
and your safety. Therefore, you must only use
this equipment if it is correctly connected to
a separate reflection-free exterior aerial. G
WARNING
Excessive levels of electromagnetic radiation
may cause damage to your health and the
health of others. Using an exterior aerial takes
into account current scientific discussions
relating to the possible health risk posed by
electromagnetic fields.
Mercedes-Benz recommends the use of an
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 a wireless device to the exterior.
R the field strength in the vehicle interior is
lower than in a vehicle that does not have
an exterior aerial.
i There are various mobile phone brackets
that may be fitted in your vehicle; in some
cases, these are country-specific.
i You can connect a Bluetooth ®
-capable
mobile phone with Audio 20 or COMAND
Online via the Bluetooth ®
interface. This
also applies if your vehicle is equipped with
convenience telephony.

Fuel grade
! Do not use diesel to refuel vehicles with a
petrol engine. Even a small quantity of die-
sel will damage the fuel injection system.
! Only refuel using unleaded petrol with at
least 95 RON/85 MON that conforms to
European standard EN 228 or E DIN
51626-1 or an equivalent specification.
Fuel with this specification may contain up
to 10 % ethanol. !
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 Petrol with metallic additives
R Diesel
Do not mix these fuels with petrol, and do
not use any additives. This can otherwise
lead to engine damage. This does not
include cleaning additives for the removal
and prevention of residue build-up. Only
cleaning additives recommended by
Mercedes-Benz should be added to petrol,
see "Additives". You can obtain further
information from any Mercedes-Benz
Service Centre.
Usually you will find information about the
fuel grade on the pump. If you cannot find the
label on the petrol pump, ask the filling sta-
tion staff.
i E10 fuel contains up to 10% bioethanol.
Your vehicle is suitable for use with E10
fuel. You can refuel your vehicle using E10
fuel.
i As a temporary measure, if the recom-
mended fuel is not available, you may also
use unleaded petrol with an octane rating
of 91 RON/82.5 MON. This may reduce
engine performance and increase fuel con-
sumption. Avoid driving at full throttle.
Information on refuelling (Y page 161).
Additives
! Do not refuel with low grade fuel and do
not use fuel additives that have not been
tested and approved for Mercedes-Benz
vehicles. Otherwise the fuel system could
malfunction or be damaged.
One of the major problems with low-grade
fuel is the creation of carbon deposits during
the process of burning fuel. Mercedes-Benz 366
Service products and capacitiesTechnical data

This depends in particular upon the age of the
AdBlue ®
.
Ammonia vapours have a pungent odour and
are particularly irritating to:
R skin
R mucous membranes
R eyes
You may experience a burning sensation in
your eyes, nose and throat, as well as cough-
ing and watering of the eyes.
Do not inhale any ammonia vapours that may
be released. Fill the AdBlue ®
tank only in well-
ventilated areas.
Low outside temperatures AdBlue
®
freezes at a temperature of approx-
imately -11 †. The vehicle is equipped with
an AdBlue ®
preheating system at the factory.
Winter operation can therefore be guaran-
teed even at temperatures below -11 †.
Additives !
Only use AdBlue ®
in accordance with ISO
22241. Do not use additives with AdBlue ®
and do not dilute AdBlue ®
with water. This
may destroy the BlueTEC exhaust gas after-
treatment system.
Purity !
Impurities in AdBlue ®
(e.g. due to other
service products, cleaning agents or dust)
lead to:
R increased emission values
R damage to the catalytic converter
R engine damage
R malfunctions in the BlueTEC ®
exhaust
gas aftertreatment system
Assuring the purity of AdBlue ®
is particularly
important with respect to avoiding malfunc-
tions in the BlueTEC exhaust gas aftertreat-
ment system. If AdBlue
®
is pumped out of the AdBlue ®
tank,
e.g. during repair work, do not use this fluid
to refill the tank. The purity of the fluid can no
longer be guaranteed.
