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.
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 used by mistake, do not start the engine 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!

General Maintenance
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-
meets all the condi-
1)
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.
Diesel fuel

Read and observe
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 at most 7% biodiesel
(B7) .
3)
On the Indian market, your vehicle will only be able to run on diesel fuel com-
pliant with standard IS 1460/Bharat IV. If diesel fuel which complies with this
standard is not available, you can refuel with diesel fuel according to standard
IS 1460/Bharat III in case of emergency.
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. The ŠKODA Part-
ners and filling stations in the relevant country will be able to provide you with
information regarding the diesel fuels available.
Preheating fuel
The vehicle is fitted with a fuel filter preheating system. This secures opera-
tion of a vehicle using diesel fuel down to an environmental temperature of
-24 °C.
