CAUTION
Even one filling of the tank with petrol that does not meet the standards 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 used by mistake, do not start the engine or
switch on the ignition! Engine parts could be significantly damaged!
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
damage to parts of the engine or exhaust system!
CAUTION
Fuels with metal components, such as LRP (lead replacement petrol) must
not 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.
The use of petrol with an octane rating higher than 95 RON in does not re-
■
sult in either a noticeable increase in power nor lower fuel consumption in ve-
hicles for which unleaded petrol 95/91, 92 or 93 RON is specified.
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.

Diesel fuel

Read and observe and
The vehicle can only be operated with diesel fuel that meets the EN 590
standard.
All diesel engines can be operated using diesel fuel with a maximum of 7% bi-
odiesel (B7) .
2)
Operation in winter - Winter-grade diesel fuel
In the cold season, only use "winter-grade diesel fuel" which will still operate
properly even at a temperature of -20 °C.
It is often the case in countries with different climatic conditions that diesel
fuels available have a different temperature characteristic. ŠKODA Partners
and filling stations in the relevant country will be able to provide you with in-
formation regarding the diesel fuels available.
Diesel fuel additives
The diesel fuel in accordance with the prescribed standards meets all the con-
ditions 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.
CAUTION
Just filling the tank once with diesel fuel that does not comply with the
■
standard, can cause severe damage to parts of the engine, the fuel and ex-
haust system!
If a different fuel other than diesel fuel, which complies to the above men-
■
tioned standards (e.g. petrol) is used, do not start the engine or switch on the
ignition! Engine parts could be significantly damaged!
Water which has collected in the fuel filter can cause engine faults.
