Petrol
Petrol types
The correct petrol types are listed on a sticker inside the fuel
tank flap.
Only unleaded petrol, corresponding to the standard DIN EN 228, may be
used for vehicles with catalytic converters (EN = “European Norm”).
Petrol types are categorised according to their octane number, e. g. 91, 95,
98 or 99. You may use petrol with a higher octane number than the one
recommended for your engine. However this has no advantage in terms of
fuel consumption and engine power.
Caution
If you must drive with fuel of a lower octane rating than recommended then
avoid driving at high engine speeds or putting demand on your engine.
Otherwise engine damage may occur. Fill up with petrol with the correct
octane number as soon as possible.
For the sake of the environment
Just one full tank of leaded fuel would seriously impair the efficiency of the
catalytic converter.
Petrol additives
The quality of the petrol influences running behaviour, performance and
service life of the engine. For this reason you should use good quality petrol
containing additives. 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, this may cause engine
problems (e.g. engine does not run smoothly or problems occur when
starting).
Not all petrol additives are effective. We recommend you use only “genuine
SEAT fuel additives for petrol engines”. They are available from SEAT Service
Centres
®. Your dealer will also be able to provide information on how to use
them.
Do not mix other fuel additives with the fuel.
Diesel
Diesel*
Diesel fuel must correspond 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 filling with fuel Ÿpage 206.
RME fuel*
Only vehicles fitted with special equipment may drive with
biodiesel fuel in accordance with standard DIN EN 14214.
The biodiesel fuel must comply with the DIN EN 14.214 (FAME) Standard.
•Biodiesel is a methylester obtained from rapeseed oil.
•DIN is a German abbreviation for “ Deutsches Institut für Normug e.V.”, the
German standards institute.
•EN means European Norm.

Safety FirstOperating instructionsTips and MaintenanceTe c h n i c a l D a t a Filter pre-heater
Your vehicle is fitted with a fuel filter pre-heater, 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 additives) with diesel fuel.
Supplementary heating system
The supplementary heating system raises the calorific capacity of the heating
while the engine is running and outside temperatures are very low. The
supplementary heating system connects and disconnects automatically.
The exhaust fumes produced are eliminated through an exhaust pipe below
the vehicle.
Note
•For short journeys, very low outside temperatures and a percentage of
biodiesel fuel of over 50 % too much smoke may be produced.
•Every time the engine is switched off, the fan continues to operate for a
short time in order to more quickly cool the heater. When refuelling it is not
necessary to wait until the fan stops operating.
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 stick 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 Ÿpage 97.
You should not do any work in the engine compartment unless you know
exactly how to carry out the jobs and have the correct tools! Have the work
carried out by a qualified workshop if you are uncertain.
All service fluids and consumables, e.g. coolant, engine oil, spark plugs and
batteries, are being constantly developed. SEAT provides a constant flow of
information to the Authorised Service Centres concerning modifications. For
this reason we recommend that you have service fluids and consumables
replaced by an Authorised Service Centre. Please observe the relevant
instructions Ÿpage 202. The engine compartment of any motor vehicle is a
hazardous area. Ÿ.
