− Never fill the spare fuel canister inside the vehicle or on it. An elec-
trostatic charge could build up during filling, causing the fuel fumes to
ignite. This may be fatally explosive. Always place the canister on the
ground to fill it.
− Insert the fuel nozzle into the mouth of the canister as far as
possible.
− If the spare fuel canister is made of metal, the filling nozzle must be
in contact with the canister during filling. This helps prevent an electro-
static charge building up.
− Never spill fuel in the vehicle or in the luggage compartment. Fuel
vapours are explosive. Danger of death.Caution
•
Fuel spills should be removed from the paintwork immediately.
•
Never run the tank completely dry. An irregular fuel supply could cause
misfiring. As a result, unburnt fuel could enter the catalytic converter and
cause damage.For the sake of the environment
Do not try to put in more fuel after the automatic filler nozzle has switched off;
this may cause the fuel to overflow if it becomes warm.
PetrolPetrol 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 RON (RON = “research octane number”). 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
•
Even one full tank 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 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 or engine problems occur,
the required additives must be added during refuelling.
DieselDiesel*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 ⇒page 195.RME fuel*
Only those vehicles fitted with special equipment (number PR
2G0 for biodiesel use) may use biodiesel corresponding to
the standard DIN EN 14214.The biodiesel fuel must comply wit h the DIN EN 14.214 (FAME) Standard.•
Biodiesel is a methylester obtained from rapeseed oil.
•
DIN is a German abbreviation for “Deutsches Institut für Normung e.V.”,
the German standards institute.
•
EN means European Norm.
•
FAME is the English abbreviation “ Fatty Acid Methyl Ester” If the date sticker of the vehicle in
cludes 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.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 me et the required standard, the fuel
filter could become clogged.Note
•
In case of low exterior temperatures and a biodiesel fuel 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 wax 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.
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.
Working in the engine compartmentSafety 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 ⇒page 200.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 ⇒page 191. The engine compartmen t of any motor vehicle is a
hazardous area ⇒.
