Petrol Petrol types
The correct petrol types are listed on a sticker inside the fuel
tank flap.Only unleaded petrol conforming to standard DIN EN 228 may be used for
vehicles with catalytic converters (EN = “European Standard”).
Fuel types are differentiated by the octane rating, e.g: 91, 95, 98 RON (RON
= “Research Octane Number”, unit for determining the knock resistance of
petrol). You may use petrol with a higher octane number than the one rec-
ommended for your engine. However, this has no advantage in terms of fuel
consumption and engine power.
CAUTION
● Even one tankful of leaded fuel would permanently impair the efficiency
of the catalytic converter.
● 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 oc-
cur, the required additives must be added during refuelling.

Diesel Diesel*
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 indi-
cates the ignition quality of the diesel fuel.
Notes on refuelling ⇒ page 194. 
Biodiesel*
CAUTION
● Your vehicle is not designed to use biodiesel fuel. Never, under any cir-
cumstances 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
fuel conforming to standard EN 590. 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 speci-
alised personnel. The composition of these fuels may severely damage the
fuel system and the engine. 

Winter driving
Diesel can thicken in winter.
Winter-grade diesel
When using “summer-grade diesel fuel”, difficulties may be experienced at
temperatures below 0°C because the fuel thickens due to wax separation.
Therefore, “winter-grade 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 the Technical Services
or filling stations in the country concerned regarding the type of diesel fuels
available.
Filter pre-heater
Your vehicle is fitted with a fuel filter glow plug system, making it well
equipped for operation in winter. This ensures that the fuel system remains
operational to approx. -24°C, provided you use winter-grade diesel which is
safe to -15°C.
However, if the fuel has waxed to such an extent that the engine will not
start at temperatures of under -24°C, simply place the vehicle in a warm
place for a while.
CAUTION
Do not mix fuel additives (thinners or similar products) with diesel fuel. Working in the engine compartment
Safety instructions on working in the engine compartment
Any work carried out in the engine compartment or on the
engine must be carried out cautiously.
Before starting any work on the engine or in the engine compart-
ment:
1. Switch off the engine and remove the key from the ignition.
2. Apply the handbrake.
3. Move the gear lever to neutral or the selector lever to position P.
4. Wait for the engine to cool down.
5. Keep children away from the vehicle.
6. Raise the bonnet ⇒ page 202.
You should not do any work in the engine compartment unless you know ex-
actly how to carry out the jobs and have the correct tools! Have the work car-
ried out by a specialised workshop if you are uncertain.
All service fluids and consumables, e.g. coolant, engine oil, spark plugs
and batteries, are under constant development. SEAT provides a constant
flow of information to the Technical Services concerning modifications. For
this reason, we recommend you to have service fluids and consumables re-
placed by a Technical Service. Please observe the relevant instructions
⇒ page 190. The engine compartment of the vehicle is a hazardous area.
