2010 Seat Leon 5D refuelling

Checking and refilling levels
220•High engine speed and full throttle can damage the engine when using
petrol with an octane rating lower than the correct grade for the engine.For the sake of the environment
Just one full tank of leaded fuel would seriously impair the efficiency of the
catalytic converter.Petrol additives
Petrol additives improve the quality of the petrol.The quality of the petrol influences the performance, power and life of the
engine. For this reason, you should use good quality petrol containing addi-
tives. These additives will help to prevent corrosion, keep the fuel system
clean and prevent deposits from building up in the engine.
If good quality petrol with additives is not available or engine problems occur,
the required additives must be added during refuelling.DieselDiesel*Diesel fuel must conform to DIN EN 590 (EN = “European Standard”). It must
have a cetane number (CN) of at least 51. The cetane number indicates the
ignition quality of the diesel fuel.
Notes on refuelling ⇒page 214.
Biodiesel*
Caution
•Your vehicle is not designed to use biodiesel fuel. Never, under any
circumstances refuel with biodiesel. The use of biodiesel fuel could damage
the engine and the fuel system. The addition of biodiesel to diesel fuel by the
diesel manufacturer in accordance with standard EN 590 or DIN 51628 is
authorised and will not cause damage to the engine or the fuel system.•The diesel engine has been designed to be used exclusively with diesel
fu el con for m i ng to sta nda rd E N 59 0 . Never refuel or use petrol, kerosene, fuel
oil or any other type of fuel. If you accidentally fill up the vehicle with the
wrong type of fuel, do not start the engine. Seek assistance from specialised
personnel. The composition of these fuels may severely damage the fuel
system and the engine.Winter driving
Diesel can thicken in winter.Winter diesel
When using summer diesel fuel, difficulties may be experienced at tempera-
tures below 0 °C because the fuel thickens due to wax separation. Therefore,
winter diesel fuel is available in some countries during the cold months. It can
be used at temperatures as low as -22 °C.
In countries with different climatic conditions the diesel fuel generally sold
has different temperature characteristics. Check with an Authorised Service
Centre or filling stations in the country concerned regarding the type of diesel
fuels available.
