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 ⇒.

WARNING
All work on the engine or in the engine compartment, e.g. checking and
refilling fluids, involves the danger of injury and scalding as well as the risk
of accident or fire.•
Never open the bonnet if you see steam, smoke or coolant escaping
from the engine compartment. Otherwis e, there is a risk of sustaining
burns. Wait until no more steam or coolant is emitted, then allow the
engine to cool before carefully opening the bonnet.
•
Switch off the engine and remove the key from the ignition.
•
Apply the handbrake and move the gear stick to neutral or selector
lever to position P.
•
Keep children away from the vehicle.
•
Never touch hot engine parts. There is a risk of burns.
•
Never spill liquids on a hot engine or on a hot exhaust gas system. This
is a fire hazard.
•
Avoid causing short-circuits in the electrical system, particularly at the
points where the jump leads are attached ⇒page 249. The battery could
explode.
•
Never touch the radiator fan. It is temperature controlled and could
start automatically, even when the engine has been switched off and the
key removed from the ignition!
•
Do not unscrew the cap on the expansion tank when the engine is hot.
If the coolant is hot, the cooling system will be pressurised!
•
Protect face, hands and arms by covering the cap with a large, thick
cloth to protect against escaping coolant and steam.
•
Always make sure you have not left any objects, such as cleaning cloths
and tools, in the engine compartment.
•
If you have to work underneath the vehicle, you must use suitable
stands additionally to support the vehicle, there is a risk of accident!. A
hydraulic jack is insufficient for securing the vehicle and there is a risk of
injury.
•
If any work has to be performed when the engine is started or with the
engine running, there is an additional, potentially fatal, safety risk from the
rotating parts, such as the drive belts, alternator, radiator fan, etc., and
from the high-voltage ignition system. You should also observe the
following points:
−Never touch the electrical wiring of the ignition system.
− Ensure that jewellery, loose cl othing and long hair do not get
trapped in rotating engine parts. Danger of death. Before starting any
work remove jewellery, tie back and cover hair, and wear tight-fitting
clothes.
− Always think carefully about pressing the accelerator if a gear is
engaged in either an automatic or manual gearbox. The vehicle could
move, even if the handbrake is applied. Danger of death.
•
If work has to be carried out on the fuel system or on electrical compo-
nents, you must observe the following sa fety notes in addition to the above
warnings:
−Always disconnect the battery. The vehicle must be unlocked when
this is done, otherwise the alarm will be triggered.
− Do not smoke.
− Never work near naked flames.
− Always have a fire extinguisher on hand.Caution
When changing or topping up service fluids, make absolutely certain that you
fill the fluids into the correct reservoirs. Failure to observe this point will result
in serious malfunctions and engine damage!

214Charging and changing the vehicle battery
The battery is maintenance-free and is checked during the
inspection service. All work on the vehicle battery requires
specialist knowledge.If you often drive short distances or if the vehicle is not driven for long
periods, the battery should be checked by a qualified workshop between the
scheduled services.
If the battery has discharged and you have problems starting the vehicle, the
battery might be damaged. If this happens, we recommend you have the
vehicle battery checked by an Authorised Service Centre where it will be re-
charged or replaced.
Charging the battery
The vehicle battery should be charged by a qualified workshop only, as
batteries using special technology have been installed and they must be
charged in a controlled environment.
Replacing a vehicle battery
The battery has been developed to suit the conditions of its location and has
special safety features.
Genuine SEAT batteries fulfil the maintenance, performance and safety spec-
ifications of your vehicle.
WARNING
•
We recommend you use only maintenance-free or cycle free leak-proof
batteries that comply with the standards T 825 06 and VW 7 50 73. This
standard applies as of 2001.
•
Before starting any work on the batteries, you must read and observe
the warnings ⇒ in “Warnings on handling the battery” on page 212.
For the sake of the environment
Batteries contain toxic substances such as sulphuric acid and lead. They
must be disposed of appropriately and must not be disposed of with ordinary
household waste.WheelsGeneral notesAvoiding damage
– If you have to drive over a kerb or similar obstacle, drive very
slowly and as near as possible at a right angle to the kerb.
– Keep grease, oil and fuel off the tyres.
– Inspect the tyres regularly for damage (cuts, cracks or blisters, etc.). Remove any foreign objects embedded in the treads.
Storing tyres
– Mark tyres when you remove them to indicate the direction of rotation. This ensures you will be able to install them correctly
when you replace them.
– 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 have to be run-in
⇒page 173.
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 chec ked 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 ty re inflation 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.
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.Puncture-proof tyres*
Puncture-proof tyres will usually allow the vehicle to continue
even when one of the tyres has a puncture.Vehicles that are factory-fitted with puncture-proof tyres
20)
indicate
on the instrument panel when there is a loss of tyre pressure. Driving on puncture-proof tyres (emergency use)
– Leave the ESP/TCS (electronic stabilisation programme)
switched on, or switch on.
– Drive carefully and at moderate speed (80 km/h maximum).
– Avoid sharp turns and rapid manouevres.
– Avoid driving over obstacles (for example, kerbs) or potholes.
– If the ESP/TCS is frequently activated, check whether there is smoke coming from the tyres or a smell of rubber, or if the vehicle
vibrates or rattles. If this is the case, stop the vehicle.
Puncture-proof tyres are marked on the tyre wall as follows: “DSST”,
“Eufonia”, “RFT”, “ROF”, “RSC”, “SSR” or “ZP”.
The tyre walls of this type of tyre are reinforced. When the tyres lose air, the
tyre walls keep the tyre up (emergency use).
Loss of air pressure in the tyre is shown on the instrument panel. The vehicle
may still be driven for at least 80 km and, under ideal conditions (for example,
no load) further.
The faulty tyre should be replaced as soon as possible. The tyre rim should be
checked for damage at a specialised workshop and replaced as necessary.
We recommend you contact your Authorised Service Centre. If more than one
tyre is being used under emergency co nditions, this reduces the distance
which can be travelled.
Starting driving in emergency conditions
When the loss in tyre pressure is displayed on the instrument panel, this
implies that at least one tyre is being driven in emergency conditions ⇒.
End of emergency operation
Do not drive on if:

220Winter tyres
Winter tyres will improve the vehicles handling on snow and
ice.In winter conditions winter tyres will considerably improve the vehicles
handling. The design of summer tyres (width, rubber compound, tread
pattern) gives less grip on ice and snow.
Winter tyres must be inflated to a pressure 0.2 bar higher than the pressures
specified for summer tyres (see sticker on tank flap).
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 218, “New tyres and wheels” determines the
following speed limits ⇒ :
Q max. 160 km/h
S max. 180 km/h
T max. 190 km/h
H max. 210 km/h
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 218, “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 to certain tyre
sizes ⇒page 258.
Snow chains must have fine-pitch link s which do not protrude more that 9
mm, including tension device.
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
Observe the fitting instructions provided by the snow chain manufacturer.
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.
