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.
Checking and refilling levels 208
•FAME is the English abbreviation “ Fatty Acid Methyl Ester”
If the date sticker of the vehicle includes the number PR 2G0 optional equip-
ment) this means that that vehicle has been prepared for biodiesel use.
Your Authorised Service Centre or automobile association will be able to
advise on where you can obtain RME biodiesel fuel.
Your Authorised Service Centre can also be consulted to know if the vehicle
has been prepared for biodiesel use.
Things to note about RME fuel (biodiesel)
•The performance of a vehicle using biodiesel maybe somewhat reduced.
•Fuel consumption of a vehicle using biodiesel may be slightly higher.
•RME fuel can be used in winter at temperatures down to approx. -10°C.
•At outside temperatures below -10°C, we recommend using winter diesel
fuel.
For technical reasons, vehicle fitted with diesel particulate filters cannot use
biodiesel under any circumstances.
Your authorized SEAT dealer will confirm whether your vehicle is prepared to
use biodiesel.
Caution
•RME fuel can damage the fuel system in vehicles that are not suitably
adjusted.
•If you decide to use biodiesel in your vehicle, please use only RME fuel
which is DIN E 14,214 compliant.
•If you use biodiesel that does not meet the required standard, the fuel
filter could become clogged.
•Your authorized SEAT dealer will be able to tell you if your vehicle is suit-
able for use with biodiesel, or whether it requires modifications in order to
use it.
•Vehicles fitted with a diesel particle filter should not use biodiesel under
any circumstance, or even start the engine, at the risk of damaging the fuel
system.
Note
•In case of low exterior temperatures and a fuel biodiesel percentage of
higher than 50%, an increase in gas emission may occur during operation of
the independent heating.
•The fuel filter may become clogged when fuel is changed to biodiesel. For
this reason, we recommend that, about every 300 or 400 km, following a fuel
change, also change the fuel filter. Also. note the instructions in the inspec-
tion and maintenance plan.
•If the vehicle is to remain parked for more than about two weeks, we
recommend filling the fuel tank with biodiesel and driving about 50 km in
order to avoid damage to the injection system.
Winter driving
Diesel can thicken in winter.
Winter-grade diesel
When using “summer-grade diesel fuel”, difficulties may be experienced at
sub-zero temperatures because the fuel thickens due to paraffin separation.
For this reason, “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 sold generally
has different temperature characteristics. Check with an Authorised Service
Centre or filling stations in the country concerned regarding the type of diesel
fuels available.

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.
