180Checking and refilling levels
–Press the tank flap with your hand to close it.
– Check that the fuel flap is correctly closed.
CAUTION
● Switch off the auxiliary heater (heater and independent heater) before
filling the tank.
● The fuel tank is full as soon as the automatic filler nozzle cuts out. Do
not continue filling, as this will fill the expansion chamber.
Note
The fuel tank capacity is around 55 litres, of which 7 litres are the reserve.
Unleaded petrol
Your vehicle must only be run on unleaded petrol that complies with the
Standard EN 228 (in Germany, also DIN 51626 – 1, or E10 for unleaded pet-
rol with 95 and 91 octane rating (RON) or DIN 51626 – 2, or E5 for unleaded
petrol with 95 and 98 RON).
Prescribed fuel – unleaded petrol (95/91 RON)
Use unleaded petrol with 95 RON. Unleaded petrol with 91 RON can also be
used, although this will result in a slight loss of power.
If, as an emergency measure, you have to fill the tank with petrol with a low-
er RON to that prescribed, use only moderate engine speeds and light throt-
tle. High engine speed and full throttle can seriously damage the engine!
Fill up with petrol with the correct RON as soon as possible.
Prescribed fuel – unleaded petrol (min. 95 RON)
Use unleaded petrol with 95 RON. If unleaded petrol with
95 RON is not available, you can fill up with petrol
with 91 RON as an emergency measure. In this case, use only moderate en-
gine speeds and a light throttle. High engine speed and full throttle can se-
riously damage the engine! Fill up with petrol with the correct RON as soon
as possible.
Petrol with a RON below 91 cannot be used, even as an emergency meas-
ure. Risk of seriously damaging the engine!
Unleaded petrol with higher RON
Unleaded petrol with a higher RON to that prescribed can be used without
limits.
In vehicles running on prescribed unleaded petrol with 95/91 RON, there is
no notable increase in power or lower fuel consumption when petrol with a
RON higher than 95 is used.
In vehicles running on prescribed unleaded petrol with min. 95 RON, there
is an increase in power and a lower fuel consumption when petrol with a
RON higher than 95 is used.
Prescribed fuel – unleaded petrol (98/(95) RON)
Use unleaded petrol with 98 RON. Unleaded petrol with 95 RON can also be
used, although this will result in a slight loss of power.
If unleaded petrol with 98 or 95 RON is not available, you can fill up with
petrol with 91 RON as an emergency measure. In this case, use only moder-
ate engine speeds and a light throttle. High engine speed and full throttle
can seriously damage the engine! Fill up with petrol with the correct RON as
soon as possible.
Petrol with a RON below 91 cannot be used, even as an emergency meas-
ure. Risk of seriously damaging the engine!
Petrol additives
The quality of the fuel influences the behaviour, performance and service
life of the engine. This is why the petrol you use should carry suitable addi-
tives already included by the petrol industry, free of metals. These additives
181
Checking and refilling levels
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. 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.
