Care and maintenance
Products for vehicle maintenance
Car-care products are available in your Tech-
nical Services. Keep the product instructions
until you have used them up. WARNING
● Car-care products can be toxic. Because of
this, they must always be kept closed in their
original container. Keep them out of the reach
of children. Failure to comply could result in
poisoning.
● Always read and observe the instructions
and warnings on the package before using
car-care products. Improper use could cause
health problems or damage the vehicle. The
use of certain products may produce noxious
vapours; they should be used in well ventila-
ted areas.
● Never use fuel, turpentine, engine oil, nail
varnish remover or other volatile fluids.
These are toxic and highly flammable. Risk of
fire and explosion.
● Before washing your vehicle, or carrying
out any maintenance, switch the engine off,
apply the handbrake firmly and remove the
key from the ignition. CAUTION
Never attempt to remove dirt, mud or dust if
the surface of the vehicle is dry. Never use a
dry cloth or sponge for cleaning purposes.
This could damage the paintwork or the win-
dows of your vehicle. Soak dirt, mud or dust
with plenty of water. For the sake of the environment
● When purchasing products for your vehicle
maintenance, select the ones which are not
harmful to the environment.
● The waste from car-care products should
not be disposed of with ordinary household
waste. Observe the disposal information on
the package. Care of the vehicle exterior
Automatic car washing tunnel The vehicle paintwork is so durable that the
vehicle can normally be washed without
problems in an automatic car wash tunnel.
However, the paintwork wear depends to a
large extent on the kind of the car wash tun-
nel, the brushes used, its water filtering and
the type of cleaning and preservative prod-
ucts.
Before going through a car wash, be sure to
take the usual precautions such as closing
the windows and sunroof. There is nothing to
note apart from that.
If the vehicle has special accessories such as
spoilers or a roof rack or two-way radio aerial,
etc., it is advisable to consult the car wash
tunnel operator first.After washing, the brakes could take some
time to respond as the brake discs and pads
could be wet, or even frozen in winter. “Dry”
the brakes by braking several times. WARNING
Water, ice and salt on the brake system can
reduce braking effectiveness. Risk of acci-
dent. CAUTION
Before putting the vehicle through the car
wash, do not tighten the aerial if it is folded
because it can be damaged. Washing by hand
Vehicle washing
– First soften the dirt and rinse it off with wa-
ter.
– Clean your vehicle from top to bottom with
a soft sponge, a glove or a brush. Use very
light pressure.
– Rinse the sponge or glove often with clean
water.
– Special car shampoo should only be used
for very stubborn dirt.
– Leave the wheels, sill panels etc. until last,
using a different sponge or glove.

Care and maintenance
Alloy wheels require regular attention to pre-
serve their appearance. If road salt and brake
dust are not often removed, the aluminium
finish will be impaired.
Always use an acid-free detergent for alloy
wheel rims.
Car polish or other abrasive agents should
not be used for maintaining the rims. If the
protective coating is damaged, e.g. by flying
stones, the damaged area should be re-
paired immediately. WARNING
Observe the safety warnings ››› in Steel
wheel rims on page 160. Underbody protection
The vehicle underbody is coated to protect it
from chemical and mechanical damage.
The protective coating can be damaged when
driving. We recommend that you check the
protective coating under the body and on the
running gear, and retouch it if necessary, be-
fore and after the winter season.
We recommend that you go to your Technical
Service to carry out repair work and addition-
al anti-corrosion work. WARNING
Do not apply underseal or anti-corrosion
coatings to the exhaust pipes, catalytic con-
verter or the heat shields on the exhaust sys-
tem. The heat of the exhaust system or the
engine could cause them to ignite. Risk of
fire. Cleaning the engine compartment
Take special care when cleaning the engine
compartment.
Anti-corrosion treatment
The engine compartment and the surface of
the power unit are given anti-corrosion treat-
ment at the factory.
Good corrosion protection is particularly im-
portant in winter when the vehicle is fre-
quently driven on salted roads. To prevent
the salt corroding the vehicle, the entire en-
gine compartment should be thoroughly
cleaned before and after winter.
Technical Services
have the proper products
for cleaning and preservation as well as the
necessary workshop equipment. For this rea-
son, we recommend having this work per-
formed by them.
The anti-corrosion protection is usually re-
moved if the engine compartment is cleaned
with grease removing solutions, or if you have the engine cleaned. On commissioning
this work, ensure that all surfaces, seams,
joints and components in the engine com-
partment are given anti-corrosion treatment.
WARNING
● When working in the engine compartment,
always observe the safety warnings
››› page 166.
● Bef
ore opening the bonnet, switch the en-
gine off, apply the handbrake firmly and al-
ways remove the key from the ignition.
● Allow the engine to cool before you clean
the engine compartment.
● Do not clean, for example, the vehicle un-
derbody, wheel arches or wheel trims without
protecting your hands and arms. You may cut
yourself on sharp-edged metal parts. Failure
to comply could result in injury.
● Moisture, ice and salt on the brake system
may affect braking effectiveness. Risk of acci-
dent. Directly after washing, avoid sudden
and sharp braking.
● Never touch the radiator fan. It is tempera-
ture-controlled and could start automatically,
even when the key is removed from the igni-
tion! For the sake of the environment
Fuel, grease and oil deposits can be removed
when the engine is washed. The polluted wa-
ter must be cleaned in an oil separator. For

● To avoid damage, stubborn stains should
be removed by a specialised workshop. Seat belt cleaning
A dirty belt may not work properly. Check all
seat belts regularly and keep them clean.
Seat belts cleaning
– Pull the dirty seat belt right out and unroll
it.
– Clean dirty seat belts with a gentle
soap
so lution.
– A
llow it to dry.
– Do not roll the seat belt up until it is dry.
If large stains form on the belts, the automat-
ic belt retractor will not work correctly. WARNING
● Do not use chemical cleaning agents on the
seat belts, as this can impair the strength of
the webbing. Ensure that seat belts do not
come into contact with corrosive fluids.
● Check the condition of the seat belts at reg-
ular intervals. If you notice that the belt web- bing, fittings, retractor mechanism or buckle
of any of the belts is damaged, the belt must
be replaced by a specialised workshop.
●
Do not attempt to repair a damaged seat
belt yourself. The seat belts must not be re-
moved or modified in any way. CAUTION
After cleaning, allow seat belts to dry com-
pletely before rolling them up. Otherwise, the
belt retractors could become damaged. Checking and refilling levels

tank is “full”. Never attempt to fill beyond
this point, as this will fill the expansion
chamber. Fuel may leak out if ambient condi-
tions are warm.
The correct fuel grade for your vehicle is giv-
en on a sticker on the inside of the fuel tank
flap. WARNING
● Fuel is highly flammable and can cause se-
rious burns and other injuries.
–Never smoke or come into contact with
sparks when filling the fuel tank of the
vehicle or a spare fuel canister with fuel.
This is an explosion hazard.
– Follow legal requirements for the use of
spare fuel canisters.
– For safety reasons we do not recommend
carrying a spare fuel canister in the vehi-
cle. The canister could be damaged in an
accident and leak.
● If, in exceptional circumstances, you have
to carry a spare fuel canister, please observe
the following:
–Never fill the spare fuel canister inside
the vehicle or on it. An electrostatic
charge could build up during filling, caus-
ing the fuel fumes to ignite. This could
cause an explosion. 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 met-
al, the filling nozzle must be in contact
with the canister during filling. This
helps prevent an electrostatic 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. Irregular
fuel supply can cause misfiring. As a result,
unburnt fuel could enter the catalytic convert-
er and cause damage.
● When filling the fuel tank after having run it
completely dry on a vehicle with a diesel en-
gine the ignition must be switched on for at
least 30 seconds before starting the engine.
Subsequently, when you start the engine it
may take longer than normal to start firing
(up to one minute). This is due to the fact that
the fuel system has to purge itself of air be-
fore starting. For the sake of the environment
Do not try to put in more fuel after the auto-
matic filler nozzle has switched off; this may
cause the fuel to overflow if it becomes warm. Petrol
Petrol types The correct petrol 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
c at
alytic converters (EN = “European Stand-
ard”).
Types of petrol differ from each other accord-
ing to the octane rating , for example: 91, 95,
98 RON (RON = “R

esearch Octane Number”,
unit for determining the knock resistance of
petrol). You may use petrol with a higher oc-
tane number than the one recommended for
your engine. However, this has no advantage
in terms of fuel consumption and engine
power. CAUTION
● Even one tankful of leaded fuel would per-
manently impair the efficiency of the catalyt-
ic 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. 164

Checking and refilling levels
For the sake of the environment
Just one full tank of leaded fuel would seri-
ously impair the efficiency of the catalytic
converter. Petrol additives
The quality of the fuel influences the behav-
iour, power and service life of the engine.
This is why the petrol you use should carry
suitable additives already included by the
petrol industry, free of metals. These addi-
tives will help to prevent corrosion, keep the
fuel system clean and prevent deposits from
building up in the engine.
If good-quality petrol with metal-free addi-
tives is not available or engine problems
arise, the necessary additives must be added
when refuelling.
Not all petrol additives have been shown to
be effective. The use of unsuitable petrol ad-
ditives may cause significant damage to the
engine and the catalytic converter. Metal ad-
ditives should never be used. Metal additives
may also be contained in petrol additives for
improving anti-detonation ratings or octane
ratings.
SEAT recommends “genuine Volkswagen
Group fuel additives for petrol engines”.
These additives can be bought at SEAT deal- ers, where information on how to use them
can also be obtained. CAUTION
Do not refuel if the filler indicates that the
fuel contains metal. LRP (lead replacement
petrol) fuels contain high concentrations of
metal additives. Using them may damage the
engine! Diesel
Diesel* Diesel fuel
must conform to DIN EN 590 (EN =
“European Standard”). It must have a cetane
number (CN) of at least 51. The cetane num-
ber indicates the ignition quality of the diesel
fuel.
Notes on refuelling ›››
page 163.
Biodiesel* CAUTION
● Your vehicle is not designed to use biodie-
sel fuel. Never, under any circumstances re-
fuel with biodiesel. The use of biodiesel fuel
could damage the engine and the fuel sys-
tem. The addition of biodiesel to diesel fuel
by the diesel manufacturer in accordance with standard EN 590 or DIN 51628 is author-
ised and will not cause damage to the engine
or the fuel system.
● The diesel engine has been designed to be
used exclusively with diesel fuel conforming
to standard EN 590. Never refuel or use pet-
rol, 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 per-
sonnel. The composition of these fuels may
severely damage the fuel system and the en-
gine. Winter operation
Winter-grade diesel
When using “summer-grade diesel fuel”, dif-
ficulties may be experienced at temperatures
below 0 °C (+32 °F) because the fuel thickens
due to wax separation. For this reason, “win-
ter-grade diesel fuel” is available in some
countries during the cold months. It can be
used at temperatures as low as -22 °C (-8 ºF).
In countries with different climatic conditions
the diesel fuel generally sold has different
temperature characteristics. Check with the
Technical Services or filling stations in the
country concerned regarding the type of die-
sel fuels available.

Filter pre-heater
Your vehicle is fitted with a fuel filter glow
plug system, making it well equipped for op-
eration in winter. This ensures that the fuel
system remains operational to approx. -24 °C
(-11 ºF), provided you use winter-grade die-
sel which is safe to -15 °C (+5 °F).
However, if the fuel has waxed to such an ex-
tent that the engine will not start at tempera-
tures of under -24 °C (-11 °F), simply place
the vehicle in a warm place for a while. CAUTION
Do not mix fuel additives, the so-called “thin-
ners”, or similar additives with diesel fuel. Working in the engine
compartment
Safety instructions on working in the
engine compartment Before starting any work on the engine or in
the engine compartment:
1. Switch off the engine and remove the key
from the ignition.
2. Apply the handbrake.
3. Move the gear lever to neutral or the selec- tor lever to position P. 4. Wait for the engine to cool down.
5. Keep children away from the vehicle.
6. Raise the bonnet
››› page 167.
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 specialised
workshop if you are uncertain.
All service fluids and consumables, e.g. cool-
ant, engine oil, spark plugs and batteries,
are under constant development. SEAT pro-
vides a constant flow of information to Tech-
nical Services concerning modifications. For
this reason, we recommend you have service
fluids and consumables replaced by a Techni-
cal Service. Please observe the relevant in-
structions ››› page 155 . The engine compart-
ment of
the vehicle is a hazardous area ››› .
WARNING
All work on the engine or in the engine com-
partment, e.g. checking and refilling fluids,
involves the danger of injury and burns, acci-
dents and even fire.
● Never open the bonnet if you see steam,
smoke or coolant escaping from the engine
compartment. Otherwise, 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
lever 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 electri-
cal system, particularly at the points where
the jump leads are attached ››› page 188. The
battery could explode.
● Never touch the radiator fan. It is tempera-
ture controlled and could start automatically,
even when the engine has been switched off
and the key removed from the ignition!
● Never cover the engine with additional in-
sulating materials such as a blanket. Risk of
fire!
● Do not unscrew the cap on the coolant ex-
pansion 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 ob-
jects, such as cleaning cloths or tools, in the
engine compartment.
● If you have to work underneath the vehicle,
you must use suitable stands additionally to 166

Checking and refilling levels
support the vehicle, there is a risk of acci-
dent!. A hydraulic jack is insufficient for se-
curing 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:
– Never touch the electrical wiring of the
ignition system.
– Ensure that jewellery, loose clothing 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-fit-
ting clothes.
– Never accelerate with a gear engaged
without taking the necessary precau-
tions. 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 components, you
must observe the following safety notes in
addition to the above warnings:
– Always disconnect the battery from the
on-board network. 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 topping up service fluids, make sure
not to mistake them. Using the wrong fluids
could cause serious malfunctions and engine
damage! For the sake of the environment
Service fluids leaks are harmful to the envi-
ronment. For this reason you should make
regular checks on the ground underneath
your vehicle. If you find spots of oil or other
fluids, have your vehicle inspected in a speci-
alised workshop. Opening the bonnet
Read the additional information carefully

The bonnet is released from inside the vehi-
cle.
Before opening the bonnet ensure that the
windscreen wipers are in rest position. WARNING
Hot coolant can scald!
● Never open the bonnet if you see steam,
smoke or coolant escaping from the engine
compartment. ●
Wait until no more steam, smoke or coolant
is emitted from the bonnet, then carefully
open the bonnet.
● When working in the engine compartment,
always observe the safety warnings
››› page 166. Closing the bonnet
–
Slightly lift the bonnet.
– Release the bonnet stay and replace it in its
support.
– At a height of approximately 30 cm let it fall
so it locks.
If the bonnet does not close, do not press
downwards. Open it again and let it fall as
mentioned above. WARNING
If the bonnet is not closed properly, it could
open while you are driving and completely
obscure your view of the road. Risk of acci-
dent.
● After closing the bonnet, always check that
it is properly secured. The bonnet must be
flush with the surrounding body panels.
● If you notice that the bonnet latch is not se-
cured when the vehicle is moving, stop the
vehicle immediately and close the bonnet
properly. Risk of accident. 167Technical specifications

The essentials

Advice
If you often drive short distances or if the ve-
hicle is not driven for long periods, the bat-
tery should be checked by a specialised
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 rec-
ommend you have the vehicle battery
checked by a Technical Service where it will
be re-charged or replaced.
Charging the battery
The vehicle battery should be charged by a
specialised workshop only, as batteries us-
ing special technology have been installed
and they must be charged in a controlled en-
vironment.
Replacing a vehicle battery
The battery has been developed to suit the
conditions of its location and has special
safety features.
Genuine SEAT batteries meet the mainte-
nance, performance and safety specifications
of your vehicle. WARNING
● We recommend you use only maintenance-
free or cycle free leak-proof batteries which
comply with 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 174. For the sake of the environment
Batteries contain toxic substances such as
sulphuric acid and lead. They must be dis-
posed of appropriately and must not be dis-
posed of with ordinary household waste. Wheels
Wheels and tyres General notes Avoiding 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 damage
(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 ro-
tation when they are installed again.
– When removed, the wheels and/or tyres
should be stored in a cool, dry and prefera-
bly 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 134.
The tread depth of new tyres may vary, ac-
cording to the type and make of tyre and the
tread pattern.

Wheels
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. They
should be checked immediately by a Techni-
cal Service.
Tyres with directional tread pattern
An arrow on the tyre sidewall indicates the di-
rection of rotation on tyres with directional
tread. Always observe the direction of rota-
tion indicated when fitting the wheel. This
guarantees optimum grip and helps to avoid
aquaplaning, excessive noise and wear. WARNING
● New tyres do not have maximum grip dur-
ing the first 500 km. Drive particularly care-
fully to avoid possible accidents.
● Never drive with damaged tyres. This may
cause an accident.
● If you notice unusual vibrations or if the ve-
hicle 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 fuel tank flap. 1. Read the required tyre inflation pressure
from the sticker. The values refer to Sum-
mer tyres.
2. The tyre pressures should only be checked when the tyres are cold. The slightly raised
pressures of warm tyres must not be re-
duced.
3. Adjust the tyre pressure to the load you are carrying.
Tyre pressure
The correct tyre pressure is especially impor-
tant 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 in-
sufficient 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 prematurely and the vehi-
cle will not handle well. Risk of accident! For the sake of the environment
Under-inflated tyres will increase fuel con-
sumption. Tyre useful life

The essentials

Advice
Depending on the make, there will be 6 to 8
of them evenly spaced around the tyre. Mark-
ings on the tyre sidewall (for instance the let-
ters “TWI” or other symbols) indicate the po-
sitions of the tread wear indicators. The mini-
mum tread depth required by law is 1.6 mm
(measured in the tread grooves next to the
tread wear indicators). Worn tyres must be re-
placed. Different figures may apply in export
countries ››› .
Tyre pressure
Incorrect tyre pressure causes premature
wear and could cause tyre blow-out. For this
reason, the tyre pressure should be checked
at least once per month ››› page 177.
Driving style
Fast cornering, heavy acceleration and hard
braking all increase tyre wear.
Changing wheels around
If the front tyres are worn considerably more
than the rear ones it is advisable to change
them around as shown ››› Fig. 155 . The use-
f u
l life of all the tyres will then be about the
same time.
Wheel balance
The wheels on new vehicles are balanced.
However, various factors encountered in nor-
mal driving can cause them to become unbal-
anced, which results in steering vibration. Unbalanced wheels should be rebalanced, as
they otherwise cause excessive wear on
steering, suspension and tyres. A wheel must
also be rebalanced when a new tyre is fitted.
Incorrect wheel alignment
Incorrect wheel alignment causes excessive
tyre wear, impairing the safety of the vehicle.
If tyres show excessive wear, you should
have the wheel alignment checked by a Tech-
nical Service.
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 wear indicators are worn
››› page 177. Failure to follow this instruction
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 in-
sufficient 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 pressures.
● If tyres show excessive wear, you should
have the running gear checked by a Technical
Service.
● Keep chemicals such as oil, fuel and brake
fluid away from tyres.
● Damaged wheels and tyres must be re-
placed immediately! For the sake of the environment
Under-inflated tyres will increase fuel con-
sumption. 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. Those approved
by SEAT are specially matched to the charac-
teristics of the vehicle and make a major con-
tribution to good road-holding and safe han-
dling
››› .
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 des-
ignations makes it easier to choose the cor-
rect tyres. Radial tyres have the tyre designa-
tions marked on the sidewall, for example: 195/65 R15 91T
