WARNING Risk of accident due t
o
improper work on two-way radios
If two-way radios are manipulated or r
etroNt-
ted incorrectly, the electromagnetic radiation
from the two-way radios can interfere with the
vehicle electronics and jeopardise the operat-
ing safety of the vehicle. 
You should have all work on electrical
and electr

onic components carried out
at a qualiNed specialist workshop. &
WARNING Risk of accident due t
o
improper operation of two-way radios
If you use two-way radios in the vehicle
im
properly, their electromagnetic radiation
can disrupt the vehicle's electronics. This is
the case in the following situations, in particu-
lar:
= The two-way radio is not connected to an
exterior aerial.
= The exterior aerial is Ntted incorrectly or is
not a low-reOection aerial.
This could jeopardise the operating safety of
the vehicle. 
Have the lo
w-reOection exterior aerial Nt-
ted at a qualiNed specialist workshop. 
When operating two-way radios in the
v

ehicle, always connect them to the low-
reOection exterior aerial. Technical data

Change immediately out of clothing that
has come int
o contact with fuel. Flexible-fuel vehicles can be refuelled with the fol-
lo

wing fuel types:
= unleaded petrol
= E85 fuel
= a mixture of E85 fuel and unleaded petrol
Flexible-fuel vehicles can be identiNed by the
Ethanol up to E85 sticker on the inside of the fuel
Nller Oap.
Depending on the country, the fuels you can use

NOTE Damag
e caused by the wrong fuel Even small amounts of the wrong fuel could
r

esult in damage to the fuel system, the
engine and the emission control system. 
Only refuel using unleaded, sulphur-free
spar
k-ignition engine fuel that conforms
to European EN 228, or an equivalent
speciNcation.
Fuel of this speciNcation ma
y contain up to
10% ethanol by volume. Your vehicle is suita-
ble for use with E10 fuel. 
See the information label in fuel Nller Oap
f
or other compatible fuels .
Never refuel with one of the following fuels: = Diesel
= R

egular petrol with an octane number
lower than 91 RON
= Petrol with more than 3% methanol by vol-
ume, e.g. M15, M30
= Petrol with additives containing metal Technical data
435

If you have accidentally refuelled with the
wr ong fuel: 
Do not switch on the vehicle. 
Consult a q
ualiNed specialist workshop.Compatibility indications for fuel:
1 For petrol with a maximum of 5% ethanol by
v
olume
2 For petrol with a maximum of 10% ethanol by
v
olume
The compatibility indications for fuel on the vehi-
cle accor
ding to European standard EN 16942
can be found on the information label on the fuel Nller
Oap or on t
he fuel dispenser or pump nozzle

If the available fuel is not suPciently low in sul-
phur, it may produce unpleasant odours.
The recommended octane number can be found
on the information label on the fuel Nller Oap
(  page 197).
If the recommended fuel is not available, you may
also temporarily use regular unleaded petrol with
an octane number of at least 91 RON.
This may reduce engine output and increase fuel
consumption.
Never refuel using petrol with an even lower RON.
Further information on fuel can be obtained at a
Nlling station or a qualiNed specialist workshop.
Information on additives in petrol (vehicles with
petrol engine)
Observe the notes on operating Ouids
( page 434). *
NOTE Damag e from use of unsuitable
