Unleaded petrol
First read and observe the introductory information and safety warn-
ings
on page 204.
Your vehicle can only be operated with unleaded petrol in compliance with the
EN 228 1)
standard.
All petrol engines can be operated using petrol that contains at most 10% bioe-
thanol (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 oc-
tane ratings 91, 92 or 93 RON can also be used, but may result in a slight loss in
performance.
Prescribed fuel - unleaded petrol min. 95 RON Use unleaded fuel with the octane rating 95 RON or higher.
In case of necessity, you can refuel with petrol with the octane ratings 91, 92 or
93 RON, if petrol with the octane rating 95 RON is not available »
.
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 results in a slight loss in performance.
In case of necessity, 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 availa-
ble »

Fuel additives
Unleaded petrol in accordance with the EN 228 standard 1 )
meets all the condi-
tions for a smooth-running engine. We therefore recommend that no fuel addi-
tives are used. This can result in considerable damage to parts of the engine or
the exhaust system.
CAUTION■ Even filling the tank with leaded 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! We recom-
mend that you have the fuel system cleaned by a specialist garage.
CAUTION
■ If, in an emergency, the vehicle has to be refuelled with petrol of a lower octane
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 oc-
tane 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. LRP(lead replacement petrol) fuels with metal-
lic components may not be used. There is a risk of causing considerable damage
to parts of the engine or exhaust system!■
Fuels with metallic content may not be used. There is a risk of causing consider-
able damage to parts of the engine or 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.
205Inspecting and replenishing

Note■Unleaded petrol that has a higher octane number than that required by the en-
gine 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 noticeable
power increase or a lower fuel consumption.
■
On vehicles using prescribed unleaded petrol of min. 95 RON, the use of petrol
with a higher octane number than 95 RON can increase the power and reduce
fuel consumption.

Diesel fuel
First read and observe the introductory information and safety warn-ings
on page 204.
Your vehicle can only be operated with diesel fuel that meets the EN 5901)
stand-
ard.
All diesel engines can be operated using diesel fuel with at most 7% biodiesel
(B7) 2)
.
For the Indian market, your vehicle can run only on diesel fuel compliant 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 fuelsavailable have a different temperature characteristic. ŠKODA Partners and filling
stations in the relevant country will be able to provide you with information re-
garding the diesel fuels available.
Preheating fuel
The vehicle is fitted with a fuel filter preheating system. This secures operation of a vehicle using diesel fuel down to an environmental temperature of -25 °C.
Diesel fuel additives
Additives, so-called “flow improvers ” (petrol and similar agents) should not be mixed with the diesel fuel. This can cause serious damage to engine or exhaust system parts.
CAUTION
■ Just filling the tank once with diesel fuel that does not comply with the stand-
ard, can cause severe damage to parts of the engine, the fuel and exhaust sys-
tem!■
If a different fuel other than diesel fuel, which complies to the above mentioned
standards (e.g. petrol) is used by mistake do not start the engine or switch on the
ignition! Extensive damage to engine parts can occur! We recommend that you
have the fuel system cleaned by a specialist garage.
■
Water which has collected in the fuel filter can cause engine faults.
CAUTION
■ Your vehicle cannot be operated with biofuel RME, therefore this fuel must not
be refuelled and driven. The use of biofuel RME can cause considerable damage
to parts of the engine or fuel system.■
Additives, so-called “flow improvers” (petrol and similar agents) should not be
mixed with the diesel fuel. This can cause serious damage to engine or exhaust system parts.
