178Petrol 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 176.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.•Biodiesel 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 standard DIN 51628.Caution
•RME fuel can damage the fuel system in vehicles which 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.Note
•In case of low outside 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 fu el is changed to biodiesel. For
this reason, we recommend that, after driving 300 or 400 km, the fuel filter
should also be changed after a fuel change. Also note the instructions in the
Maintenance Programme.•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.

New tyres
New tyres must be run in ⇒
page 156.
The tread depth of new tyres may vary, according to the type and make of tyre
and the tread pattern.
Concealed damage
Damage to tyres and rims is often not readily visible. If you notice unusual
vibrations or the car pulling to one side, this may indicate that one of the tyres
is damaged. The tyres should be checked immediately by an Authorised
Service Centre.
Tyres with directional tread pattern
An arrow on the tyre sidewall indicates the direction of rotation on tyres with
directional tread. Always observe the direction of rotation indicated when
fitting the wheel. This guarantees optimum grip and helps to avoid aqua-
planing, excessive noise and wear.
WARNING
•New tyres do not have maximum grip in the first 500 km. Drive particu-
larly carefully to avoid risk of accident.•Never drive with damaged tyres. This may cause an accident.•If you notice unusual vibration or if the vehicle pulls to one side when
driving, stop the vehicle immediately and check the tyres for damage.
Checking tyre pressure
The correct tyre pressure can be seen on the sticker on the
inside of the tank flap.1. Read the required tyre inflatio n pressure from the sticker. The
values refer to Summer tyres. 2. The tyre pressures should only be checked when the tyres are
cold. The slightly raised pressures of warm tyres must not be
reduced.
3. Adjust the tyre pressure to the load you are carrying.
Tyre pressure
The correct tyre pressure is especially important at high speeds. The pressure
should therefore be checked at least once a month and before starting a
journey.
WARNING
A tyre can easily burst if the pressure is too low, causing an accident!•At continuously high speeds, a tyre with insufficient pressure flexes
more. In this way it becomes too hot, and this can cause tread separation
and tyre blow-out. Always observe the recommended tyre pressures.•If the tyre pressure is too low or too high, the tyres will wear prema-
turely and the vehicle will not handle well. Risk of accident!For the sake of the environment
Under-inflated tyres will increase fuel consumption.

WARNING
There is a serious danger of accidents if a tyre bursts during driving!•The tyres must be replaced at the latest when the tread is worn down to
the tread wear indicators. Failure to do so could result in an accident. Worn
tyres do not grip well at high speeds on wet roads. There is also a greater
risk of “aquaplaning” •At continuously high speeds, a tyre with insufficient pressure flexes
more. This causes it to overheat. This can cause tread separation and tyre
blow-out. Risk of accident. Always observe the recommended tyre pres-
sures.•If tyres show excessive wear, you should have the running gear checked
by an Authorised Service Centre.•Keep chemicals such as oil, fuel and brake fluid away from tyres.•Damaged wheels and tyres must be replaced immediately!For the sake of the environment
Under-inflated tyres will increase fuel consumption.New tyres and wheels
New tyres and wheels have to be run-in.The tyres and wheel rims are an essential part of the vehicle's design. The
tyres and rims approved by SEAT are specially matched to the characteristics
of the vehicle and make a major contribution to good road holding and safe
handling ⇒.
Tyres should be replaced at least in pairs and not individually (i.e. both front
tyres or both rear tyres together). A knowledge of tyre designations makes it easier to choose the correct tyres. Radial tyres have the tyre designations
marked on the sidewall, for example:
195/65 R15 91T
This contains the following information:
195 Tyre width in mm
65 Height/width ratio in %
RTyre construction: Radial
15 Rim diameter in inches
91 Load rating code
TSpeed rating
The tyres could also have the following information:
•A direction of rotation symbol•“Reinforced” denotes heavy-duty tyres.
The manufacturing date is also indicated on the tyre sidewall (possibly only
on the inner side of the wheel).
“DOT ... 1103 ...” means, for example, that the tyre was produced in the 11th
week of 2003.
We recommend that work on tyres and wheels is carried out by an Authorised
Service Centre. 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 tyres.
Any Authorised Service Centre has full information on the technical require-
ments when installing or changing tyres, wheels or wheel trims.WARNING
•We recommend that you use only wheels and tyres which have been
approved by SEAT for your model. Failure to do so could impair vehicle
handling. Risk of accident.

Winter tyres must be fitted on all four wheels.
Information on permitted
winter tyre sizes can be found in the vehicle's regis-
tration documents. Use only radial winter tyres. All tyre sizes listed in the
vehicle documentation also apply to winter tyres.
Winter tyres lose their effectiveness when the tread is worn down to a depth
of 4 mm.
The speed rating code ⇒page 197, “New tyres and wheels” determines the
following speed limits for winter tyres: ⇒
In some countries, vehicles which can exceed the speed rating of the fitted
tyre must have an appropriate sticker in the driver's field of view. These
stickers are available from your Authorised Service Centre. The legal require-
ments of each country must be followed.
Do not have winter tyres fitted for unnecessarily long periods. Vehicles with
summer tyres handle better when the roads are free of snow and ice.
If you have a flat tyre, please refer to the notes on the spare wheel
⇒ page 197, “New tyres and wheels”.
WARNING
The maximum speed for the winter tyres must not be exceeded. Otherwise,
this could lead to tyre damage and thus, an accident risk.
For the sake of the environment
Fit your summer tyres in good time. They are quieter, do not wear so quickly
and reduce fuel consumption.Snow chainsSnow chains may be fitted only to the front wheels, and only for the following
tyres:
Remove wheel hub covers and trim rings before fitting snow chains. For safety
reasons cover caps, available in any Authorised Service Centre, must then be
fitted over the wheel bolts.
WARNING
Snow chains should be correctly tightened in accordance with the manu-
facturer's instructions. This will prevent the chains coming into contact
with the wheel housing.
Caution
You must remove the snow chains to drive on roads which are free of snow.
Otherwise they will impair handling, damage the tyres and wear out very
quickly.

Data on fuel consumptionFuel consumption
The consumption and emission details shown on the vehicle
data sticker differ from one vehicle to another.The fuel consumption and CO
2 emissions of the vehicle can be found on the
vehicle data sticker.
The fuel consumption and emissions figures given are based on the vehicle
weight category, which is determined according to the engine/gearbox
combination and the equipment fitted.
The consumption and emission figures are calculated in accordance with the
EC test requirements 1999/100/EC. These test requirements specify a real-
istic test method based on normal everyday driving.
The following test conditions are applied:
Note
•Actual consumption may vary from quoted test values, depending on
personal driving style, road and traffic conditions, the weather and the
vehicle condition.WeightsKerb weight refers to the basic model with a fuel tank filled to 90% capacity
and without optional extras. The figure quoted includes 75 kg to allow for the
weight of the driver.
For special versions and optional equipment fittings or for the addition of
accessories, the weight of the vehicle will increase ⇒.
WARNING
•Please note that the centre of gravity may shift when transporting
heavy objects; this may affect the vehicle's handling and lead to an acci-
dent. Always adjust your speed and driving style to suit road conditions
and requirements.•Never exceed the gross axle weight rating or the gross vehicle weight
rating. If the allowed axle load or the allowed total weight is exceeded, the
driving characteristics of the vehicle may change, leading to accidents,
injuries and damage to the vehicle.
Urban cycle
The urban cycle starts with an engine cold start. City driving
is then simulated.
Extra urban
cycle
In the extra urban cycle simulation the vehicle frequently
accelerates and brakes in all gears, as in normal everyday
driving. The road speed ranges from 0 to 120 km/h.
To ta l co n-
sumption
The average total consumption is calculated with a weighting
of around 37% for the urban cycle and 63% for the extra
urban cycle.
CO2 emis-
sions
The exhaust gases are collected during both driving cycles to
calculate carbon dioxide emissions. The gas composition is
then analysed to evaluate the CO
2 content and other emis-
sions.
