224PetrolPetrol types
The recommended fuel 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 Standard”).
Fuel types are differentiated by the octane rating, e.g: 91, 95, 98 RON (RON
= “Regulation Octane Number, unit for determining the knock resistance of
petrol”). You may use petrol with a higher octane number than the one recom-
mended for your engine. However, this has no advantage in terms of fuel
consumption and engine power.
The correct fuel type for your vehicle is given in the technical table for the
engine. Section “Technical Data”
Caution
•Petrol that follows EN 228 may be mixed with small quantities of ethanol.
However, the so-called “bioethanol fuels” available at commercial establish-
ments, e.g. with reference E50 or E85, which contain a high percentage of
ethanol, may not be used, as they will damage the fuel system.•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 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 refuelling ⇒page 222.Biodiesel*The biodiesel fuel must comply with the DIN EN 14.214 (FAME) Standard.•Biodiesel is a methyl ester obtained from rapeseed oil.•DIN is the German abbreviation for “ Deutsches Institut für N ormung e.V.”,
the German standards institute.•EN means European Norm.•FAME is the English abbreviation for “ Fatty Acid Methyl Ester”.

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 is resistant to the cold down to approx. -10°C.•At temperatures below -10°C, we recommend using winter diesel fuel.•Your vehicle is designed to be refuelled with up to a maximum of 7%
blended biodiesel, in accordance with the DIN 51628 standard.Caution
•RME fuel can damage the fuel system in vehicles which are not suitably
adjusted.•If you refuel with biodiesel, please be sure that it conforms to the
DIN E 14.214 standard.•If you use biodiesel that does not meet the required standard, the fuel
filter could become clogged.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 you that, when having run 300 or 400 km after a
fuel change, the fuel filter change must also be done. Also note the instruc-
tions in the Inspection 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.
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 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.

Engine oilGeneral notesWe recommend that the oil change should be performed by an Authorised
Service Centre or a qualified workshop, according to the Maintenance
Program. The correct oil specifications for your engine are listed in the
⇒page 229,
“Oil properties”.
Check that the specifications quoted (VW standards) appear on the container
either singly or in combination with other specifications.
Flexible maintenance intervals (Extended Service Intervals*)
Special lubricating oils have been de ve lop
ed in the framework of the SEAT
Booklet “Extended Se rvice Intervals” Maintenance Programme
⇒ page 229.
This typ
e of oil must be used if you intend to take advantage of the prolonga-
tion of the maintenance intervals in the framework of the “Extended Service
Intervals” program.
•Do not mix the LongLife oil with oil intended for fixed service intervals, as
the requirements for the extended service intervals are then no longer guar-
anteed.•Only in exceptional circumstances, if the engine oil level is too low
⇒ page 230 and LongLife oil is not available, it is permitted to top up (once)
with oil for fixed service intervals ⇒ page 229 (up to a maximum of 0.5
litres).
Fixed service intervals*
If “Extended Service Intervals” are not applied to your vehicle, you can use
oils for fixed service intervals ⇒ page 229. In this case, your vehicle must be
serviced after a fixed interval of 1 year / 15,000 km (10,000 miles) (see the
Maintenance Program).•In exceptional circumstances, if the engine oil level is too low
⇒ page 230 and you cannot obtain the oil specified for your vehicle, you can
put in a small quantity of oil conforming to the specification ACEA A2 or
ACEA A3 (petrol engines) or ACEA B3 or ACEA B4 (diesel engines) (up to 0.5l).
Vehicles with diesel particulate filter*
The Maintenance Program states whether your vehicle is fitted with a diesel
particulate filter.

These oils are only useful in a climate that is constantly very cold or very
warm.
Engine oil additives
No type of additive should be mixed with the engine oil. The deterioration
caused by these additives is not covered by the warranty.
Note
Before a long trip, we recommend finding an engine oil that conforms to the
corresponding VW specifications and keeping it in the vehicle. This way, the
correct engine oil will always be available for a top-up if needed.

238Topping up and changing the brake fluid
It is best to have the brake fluid changed by a professional.Brake fluid absorbs damp. Therefore, in the course of time it will absorb water
from the ambient air. If the water content in the brake fluid is too high, the
brake system could corrode. In addition, the boiling point of the brake fluid
will be considerably reduced. This could adversely affect the braking ability in
certain circumstances.
For this reason the brake fluid must be changed periodically.
Your vehicle's Service Schedule will tell you when the brake fluid has to be
renewed.
We recommend you have the brake fluid changed as part of a regular Inspec-
tion Service at your garage. They are familiar with the procedure and have the
necessary special tools and spare parts as well as the proper facilities for
disposing of the old fluid.
Use only the genuine brake fluid specified by the factory Specialist garages
know that the brake fluid -DOT 4- is factory approved. The brake fluid must be
new.
WARNING
•Therefore, it must always be kept cl osed in its original container. Keep
out of the reach of children. Failure to comply could result in poisoning.•Heavy use of the brakes may cause a vapour lock if the brake fluid is left
in the system for too long. This would seriously affect the efficiency of the
brakes and the safety of the car, leading to the risk of accident.Caution
Please note that brake fluid will attack the paintwork on contact.
For the sake of the environment
If the fluid has to be drained out of the brake system, use an appropriate
container to catch the used brake fluid and dispose of it in the proper
manner.BatteryGeneral notes
All work on batteries requires specialist knowledge.The battery is virtually maintenance-free and is checked in the Inspection
Services.
We recommend that you replace a battery once it is older than 5 years.
Disconnecting the battery
If the battery is disconnected, some of the vehicle's functions will become
inoperative (e.g. electric windows). These functions will require resetting
after the battery is reconnected. For this reason, the battery should only be
disconnected from the vehicle's electrical system when absolutely necessary.
Long periods of non-use
The battery will gradually lose its charge because certain electrical equip-
ment continues to draw current even when the ignition is off. If you park the
vehicle for long periods of time in winter you should take the battery out of
the vehicle and keep it in a frost-proof room. Store the battery in a place
where it cannot “freeze up” and become damaged. At warm outside temper-
atures it is sufficient to disconnect the negative terminal of the battery. Even
when the battery is not connected you should charge it from time to time.
