194change down into a lower gear or range (depending on the type of trans-
mission). This makes use of engine braking and relieves the brakes.•Never let the brakes “drag” by applying light pressure. Continuous
braking will cause the brakes to overheat and the braking distance will
increase. Apply and then release the brakes alternately.•Never let the vehicle run with the engine switched off. The braking
distance is increased considerably when the brake servo is not active.•If the brake fluid loses its viscosity and is subjected to heavy use,
vapour bubbles can form in the brake system. This reduces the efficiency of
the brakes.•Non-standard or damaged front spoilers could restrict the airflow to the
brakes and cause them to overheat. Before purchasing accessories please
observe the relevant instructions ⇒page 212, “Technical modifications”.•If a brake circuit fails, the braking distance will be increased consider-
ably. Contact a specialised workshop immediately and avoid unnecessary
journeys.
Exhaust gas purification systemCatalytic converter*To maintain the useful life of the catalytic converter
– Use only unleaded petrol with petrol engines, as lead damages the catalytic converter.
– Do not let the fuel get too low in the tank. – For engine oil changes, do not replenish with too much engine oil
⇒page 226, “Topping up engine oil E”.
– Never tow the vehicle to start it, use jump leads if necessary ⇒page 267.
If you notice misfiring, uneven running or loss of power when the vehicle is
moving, reduce speed immediately and have the vehicle inspected at the
nearest specialised workshop. In general, the exhaust gas warning lamp will
light up when any of the described symptoms occur ⇒page 77. If this
happens, unburnt fuel can enter the exhaust system and escape into the envi-
ronment. The catalytic converter can also be damaged by overheating.
WARNING
The catalytic converter reaches very high temperatures! There is a risk of
fire.•Never park where the catalytic converter could come into contact with
dry grass or flammable materials under the vehicle.•Do not apply additional underseal or anti-corrosion coatings to the
exhaust pipes, catalytic converter or the heat shields on the exhaust
system. These materials could catch fire when the vehicle is being driven.Caution
Never run the fuel tank completely dry because the irregularity of the fuel
supply may cause ignition problems. This allows unburnt fuel to enter the
exhaust system, which could cause overheating and damage the catalytic
converter.
For the sake of the environment
Even when the emission control system is working perfectly, there may be a
smell of sulphur from the exhaust gas under some conditions. This depends

Save electricity
The engine activates the alternator, which produces electricity. With the need
for electricity, fuel consumption is also increased. Because of this, always
turn off electrical components when you do not need them. Examples of
components that use a lot of electricity are: the fan at high speeds, the rear
window heating or the seat heaters*.
Note
•If you vehicle has
Start-Stop, it is not recommended to disconnect this
function.•It is recommended to close the windows when driving at more than 60
km/h•Do not drive with your foot resting on the clutch pedal, as the pressure can
make the plate spin, more fuel will be used and it can burn the clutch plate
lining, causing a serious fault.•Do not hold the vehicle on a hill with the clutch, use the foot brake or hand
brake, using the latter to start. The fuel consumption will be lower and you will
prevent the clutch plate from being damaged.•On descents, use the engine brake, changing to the gear that is more suit-
able for the slope. The fuel consumption will be lower and the brakes will not
suffer.Environmental friendlinessEnvironmental protection is a top priority in the design, choice of materials
and production of your new Seat.

– Screw on the cap of the gas filler neck .
– Close the tank flap.When the hose is removed from the tank, a small amount of LPG may spill out
⇒.
The LPG tank ⇒fig. 140 in the spare wheel well has a capacity of 39 litres. If
the outside temperatures are very low, it may not be possible to completely
fill the LPG tank.
Pump attachments
There are a variety of types of LPG pump, and the methods of use may vary.
Therefore, let the pump operator fill the tank when refuelling for the first time
or fill from another pump.
Noises when refuelling with LPG
When refuelling with LPG, noises may be heard. These noises are insignifi-
cant.
WARNING
Failure to refuel or handle LPG in the correct way could result in a fire, cause
an explosion or lead to injuries.•LPG is a highly explosive and inflammable substance. It may cause
severe burns and other injury.•Switch off the engine before refuelling.•Always disconnect mobile phones and any other radiophony appli-
ances, as electromagnetic waves may produce sparks and cause a fire.•Do not remain in the vehicle while refuelling. If it is absolutely neces-
sary to enter the vehicle, close the door and touch a metal surface before
touching the attachment again. This will prevent the generation of static
electricity and any possible fires while refuelling.
•Small quantities of LPG may leak out after refuelling. If LPG comes into
contact with skin, there is a risk of freezing.•Do not smoke and always keep bare flames away from the tank during
refuelling. Failure to do so may lead to an explosion.

218Adapter for the liquid petroleum gas (LPG) filler neck
An adapter is required due to the existence of a range of
pumps with different nozzles.Fig. 141 General table of LPG filler neck adapters.
ACME adapter (adapter for Europe)
Dish Coupling Adapter (adapter for Italy)
Bayonet adapter
EURO adapter (adapter for Spain)
The supply includes the adapter for the country in question, the ACME , the
Dish Coupling , the bayonet or the EURO adapter .
The filler systems and corresponding adapters vary according to country. As
petrol stations abroad do not always have the necessary adapters for your
LPG system, we recommend you purchase the appropriate adapter before
travelling abroad. Check that the adapters are suited to your filling system.
Note
The four most common types of adapter in Europe are the ACME adapter ,
the Dish Coupling adapter , the bayonet adapter and the EURO adapter . On the whole, we recommend you carry all four adapters in your vehicle,
as some countries use more than one type of filling system. The introduction
of a single system (Euronozzle) throughout Europe is being studied.LPG fuelLPG is an alternative vehicle fuel and is a blend of propane and butane.

LPG quality and consumption
Quality requirements for LPG are regulated for all Europe in DIN EN 589 and
permit the use of LPG throughout Europe.
A difference is drawn between winter gas and summer gas. Winter gas has a
higher proportion of propane gas. As a result, the driving range of winter gas
may be lower (due to increased consumption) than that of summer gas.
LPG supplier network
The number of LPG pumps is constantly increasing.
Lists of existing LPG pumps may be found on Internet.LPG safetyA series of collision tests performed on this vehicle while running with LPG
have confirmed its high level of safety.

Technical Specifications
The safety of the LPG system guarantees operation without risk. The following
safety measures have been adopted:
•The LPG tank has a solenoid valve which closes automatically when the
engine is switched off (ignition off) or when running on petrol.•A solenoid type main valve disconnects the supply of gas to the engine
compartment when the engine is switched off or running on petrol.•A safety valve in the LPG tank with pipes to the outside prevents the gas
from entering the vehicle interior.•All anchorage points and materials have been designed to ensure the
maximum possible levels of safety.
The condition of the LPG system should be checked regularly to guarantee
safe driving conditions ⇒ . These checks are included in the Maintenance
Programme.WARNING
•If there is a smell of gas or a suspected leak, stop the vehicle immedi-
ately and switch off the ignition. Open the doors to ventilate the vehicle. Do
not carry on driving! Take the vehicle to a specialised workshop and have
the fault repaired.•Immediately extinguish any cigarettes and remove from the vehicle any
objects which might produce a spark or cause a fire, and switch off imme-
diately if gas is smelt or a leak is detected.•LGP tanks are subject to pressure and must be checked regularly. The
owner of the vehicle must check that these services are performed
correctly.•When parking the vehicle in a closed area (for example in a garage),
make sure that there is adequate ventilation, either natural or mechanical,
to neutralise the LPG in the event of a leak.
Note
For any fault in the LGP system, please refer to the SEAT web page, which lists
the workshops authorised to repair these faults.PetrolPetrol types
The recommended fuel types are listed on a sticker inside the
fuel tank flap.Only unleaded petrol conforming to 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
= “Research 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, in the Technical Data section.
Caution
•Petrol with standard EN 228 may be mixed with small quantities of
ethanol. However, the so-called “bioethanol fuels” available at commercial
establishments 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.

Checking and refilling levels
220•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 the performance, power and life of the
engine. For this reason, you should use good quality petrol containing addi-
tives. 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 conform 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 214.
Biodiesel*
Caution
•Your vehicle is not designed to use biodiesel fuel. Never, under any
circumstances refuel with biodiesel. The use of biodiesel fuel could damage
the engine and the fuel system. The addition of biodiesel to diesel fuel by the
diesel manufacturer in accordance with standard EN 590 or DIN 51628 is
authorised and will not cause damage to the engine or the fuel system.•The diesel engine has been designed to be used exclusively with diesel
fu el con for m i ng to sta nda rd E N 59 0 . Never refuel or use petrol, kerosene, fuel
oil or any other type of fuel. If you accidentally fill up the vehicle with the
wrong type of fuel, do not start the engine. Seek assistance from specialised
personnel. The composition of these fuels may severely damage the fuel
system and the engine.Winter driving
Diesel can thicken in winter.Winter diesel
When using summer diesel fuel, difficulties may be experienced at tempera-
tures below 0 °C because the fuel thickens due to wax separation. Therefore,
winter 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.

Wheels and tyresWheelsGeneral notesAvoiding damage
– If you have to drive over a kerb or similar obstacle, drive very
slowly and at a right angle.
– Keep grease, oil and fuel off the tyres.
– Inspect the tyres regularly for da mage (cuts, cracks or blisters,
etc.). Remove any foreign objects embedded in the treads.
Storing tyres
– When you remove the tyres, mark them in order to maintain the same direction of rotation when they are installed again.
– When removed, the wheels and/or tyres should be stored in a cool, dry and preferably dark location.
– Store tyres in a vertical position if they are not fitted on wheel
rims.New tyres
New tyres must be run in ⇒ page 193.
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 vehicle 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 during the first 500 km. Drive
particularly carefully to avoid possible accidents.•Never drive with damaged tyres. This may cause an accident.•If you notice unusual vibrations 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. For Winter tyres, you must add 0.2
bar to the values given on the sticker.

Driving with run-flat tyres (emergency running)
– Leave the ESP/TCS (Electronic Stability Programme) switched on,
or switch on ⇒page 186.
– Continue driving carefully and slowly (80 km/h maximum).
– Avoid sudden manoeuvres and sharp turns.
– Avoid driving over obstacles (for example kerbs) or potholes.
– Look out for the ESP/TCS intervening often, smoke coming from the tyres or the smell of rubber, the vehicle vibrating or a clat-
tering noise. If any of these occur, stop the vehicle.The run-flat tyres have a tag on the side of the tyre, with the description:
“DSST”, “Eufonia”, “RFT”, “ROF”, “RSC”, “SSR” or “ZP”.
The sides of this type of tyre are reinforced. When the tyres lose air they are
supported on the sides (emergency driving).
The loss of pressure in the tyre is shown on the instrument panel. You can
then drive a maximum of 80 km and if the circumstances are favourable (for
example, low load), even more.
The damaged tyre should be changed as soon as possible. The rim should be
checked in a specialised workshop to detect possible damage and replace it
if necessary. We recommend you contact Technical Service. If more than one
tyre is being used under emergency conditions, this reduces the distance
which can be travelled.
Starting driving in emergency conditions
When loss in tyre pressure is displayed on the instrument panel, this means
that at least one tyre is being driven in emergency conditions ⇒.
End of emergency operation
Do not drive on if:
•smoke is coming from one of the tyres,•there is a smell of rubber,•the vehicle vibrates,•there is a rattling noise.
When is it no longer possible to continue driving even using run-flat tyres?•If one of the tyres has been severely damaged in an accident, etc. If a tyre
has been badly damaged there is a risk that parts of the tread can be thrown
off and cause damage to the fuel lines, brake pipes or fuel filler.•It is also advisable to stop driving if severe vibrations occur, or if the wheel
starts overheating and gives off smoke.WARNING
When driving in emergency conditions, the driving quality of the vehicle is
considerably impaired.•The maximum permitted speed of 80 km/h is subject to road and
weather conditions. Please observe legal requirements when doing so.•Avoid sharp turns and rapid manoeuvres, and brake earlier than usual.•Avoid driving over obstacles (for example kerbs) or potholes.•If one or more tyres are being driven in emergency conditions, the
driving quality of the vehicle is impaired and there is a risk of accident.Note
•The run-flat tyres do not “deflate” on losing pressure because they are
supported on the reinforced sides. Therefore defects in the tyre cannot be
detected with a visual inspection.•Snow chains must not be used on front tyres used in emergency
conditions.
