will help to prevent corrosion, keep the fuel system clean and prevent de-
posits from building up in the engine.
If good quality petrol with metal-free additives is not available or engine
problems arise, the necessary additives must be added when refuelling
⇒ .
Not all petrol additives have been shown to be effective. The use of unsuita-
ble petrol additives may cause significant damage to the engine and the
catalytic converter. Metal additives should never be used. Metal additives
may also be contained in petrol additives for improving anti-detonation rat-
ings or octane ratings ⇒ .
SEAT recommends "genuine Volkswagen Group fuel additives for petrol en-
gines". These additives can be bought at SEAT Authorised Services, where
information on how to use them can also be obtained.
CAUTION
● Do not refuel if the filler indicates that the fuel contains metal. LRP (lead
replacement petrol) fuels contain high concentrations of metal additives.
Using them may damage the engine!
● All SEAT vehicles with petrol engines can only run on unleaded petrol.
Refuelling just once with leaded petrol disables the exhaust system!
● Use of petrol with a lower RON to that prescribed could damage the en-
gine components.
● Fuels marked as containing metal on the garage fuel pump cannot be
used. Risk of damage to most engine parts or the exhaust system!
● The use of unsuitable additives in petrol can cause damage to most en-
gine parts or the exhaust system.
Safety First Operating instructions
Diesel fuel
Your vehicle can only run on diesel fuel that complies with the Standard EN
590 (in Germany, also DIN 51628, in Austria also ÖNORM C 1590, in Russia
also GOST R 52368-2005/EN 590:2004).
Winter driving – winter-grade diesel
In winter use diesel fuel that complies with the Standard EN 590 (in Germa-
ny, also DIN 51628, in Austria also ÖNORM C 1590, in Russia also GOST R
52368-2005/EN 590:2004). "Winter-grade diesel" still performs well at
-20 °C (-4 °F).
In countries with other weather conditions, diesel is often available that be-
haves differently with regards to the temperature. The authorised SEAT deal-
ers and petrol stations in each country will inform you on the normal diesel
fuel of the country in question.
Preheating the fuel filter
The vehicle is fitted with a glow plug system for the fuel filter. Therefore, the
reliability of the diesel is ensured at ambient temperatures of down to ap-
prox. -25 °C (-13 °F).
Fuel additives
Fuel additives, known as "thinners" (petrol or similar substances) should
not be mixed with the diesel fuel.
CAUTION
● Even one tankful of diesel fuel that does not comply with the standard
could damage engine parts, the fuel system and the exhaust system!

● If fuel different to the prescribed diesel fuel (e.g. petrol) is used by mis-
take, never start the engine or switch on the ignition! Risk of serious dam-
age to the engine! Contact an authorised SEAT dealer to clean the engine
fuel system.
