Lead-free petrol

Read and observe on page 170 first.
The vehicle can only be operated with unleaded petrol in compliance with the
EN 228 standard.
1)
All petrol engines can be operated using petrol that contains at most 10% bio-
ethanol (E10).
Required fuel - unleaded petrol 95/91 or 92 or 93 RON
Use unleaded fuel with the octane rating 95 RON. Unleaded petrol with the
octane ratings 91, 92 or 93 RON can also be used, but may result in a slight
loss in performance and slightly increased fuel consumption
Prescribed fuel - unleaded petrol min. 95 RON
Use unleaded fuel with the octane rating 95 RON or higher.
If unleaded gasoline is not available with the octane number 95 RON, in an
emergency petrol with the octane rating of 91, 92 and 93 RON can be used to
fill the tank, but this leads to a slight loss of performance and a slightly in-
creased fuel consumption » .
Prescribed fuel - unleaded fuel 98/95 RON
Use unleaded fuel with the octane rating 98 RON or higher. Unleaded petrol
95 RON can also be used but this results in a slight loss in performance and
slightly increased fuel consumption.
In case of an emergency, you can refuel with petrol with the octane ratings 91,
92 or 93 RON, if unleaded fuel with octane rating 98 RON or 95 RON is not
available » .
Fuel additives
Unleaded petrol in accordance with the EN 228 standard
tions for a smooth-running engine. We therefore recommend that no fuel ad-
ditives are used. This can result in considerable damage to parts of the engine
or the exhaust system.
1) In Germany also DIN 51626-1 or E10 for unleaded petrol with octane number 91 or 95 or DIN 51626-2 or E5
for unleaded petrol with octane number 95 and 98.

General Maintenance
CAUTION
Even filling the tank with petrol that does not meet the standards once can
■
lead to serious damage to parts of the exhaust system!
If a fuel other than unleaded fuel which complies to the above mentioned
■
standards (e.g. leaded petrol) is put in the tank by mistake, do not start the en-
gine or switch on the ignition! Extensive damage to engine parts can occur!
CAUTION
If, in an emergency, the vehicle has to be refuelled with petrol of a lower oc-
■
tane number than the one prescribed, the journey must only be continued at
medium engine speeds and a low engine load. Driving at high engine revs or a
high engine load can severely damage the engine! Refuel using petrol of the
prescribed octane number as soon as possible.
Engine parts can be damaged if petrol with a lower octane number than the
■
one prescribed is used.
Even in the event of an emergency, petrol of a lower octane number than 91
■
» .
RON must not be used, otherwise the engine can be severely damaged!
CAUTION
In no case may fuel additives with metal components be used, especially not
with manganese and iron content. There is a risk of causing considerable dam-
age to parts of the engine or exhaust system!
CAUTION
Do not use fuels with metal components, such as LRP (lead replacement
petrol) may be used. There is a risk of causing considerable damage to parts of
the engine or exhaust system!
Note
Unleaded petrol that has a higher octane number than that required by the
■
engine can be used without limitations.
On vehicles with prescribed unleaded petrol 95/91, 92 or 93 RON, the use of
■
petrol with a higher octane number than 95 RON does not result in a noticea-
ble power increase or a lower fuel consumption.

On vehicles using prescribed unleaded petrol of min. 95 RON, the use of pet-

rol with a higher octane number than 95 RON can increase the power and re-
duce fuel consumption.
