WARNING
•
Never wash tyres with a cylindrical jet. Even at large spraying distances
and short cleaning times, visible and invisible damage can occur to the
tyres. This may cause an accident.
•
Moisture, ice and salt on the brakes may affect braking efficiency. Risk
of accident. If possible, avoid sudden braking immediately after washing
the vehicle. You must “dry” the brakes by applying the brakes carefully
several times ⇒ page 173, “Braking effect and braking distance”.
Cleaning alloy wheelsEvery two weeks
– Wash salt and brake dust from alloy wheels.
– Use an acid free detergent to clean the wheels.
Every three months
– Apply a hard wax compound to the wheels.Alloy wheels require regular attention to preserve their appearance. It is
important to remove road salt and brake dust by washing the wheels at
regular intervals, otherwise the finish will be impaired.
Always use an acid-free detergent for alloy wheels.
Car polish or other abrasive agents should not be used. If the protective
coating is damaged, e.g. by stone impact, the damaged area should be
repaired immediately.

Underbody sealant
The underside of the vehicle is coated to protect it from corro-
sion and damage.The protective coating could be damage d when driving. We recommend that
the protective coating under the body and on the running gear should be
checked, and reinstated if necessary, before and after the winter season.
We recommend that repair work and addi tional anti-corrosion work is carried
out by your Authorised Service Centre.
WARNING
Do not apply underseal or anti-corros ion coatings to the exhaust pipes,
catalytic converter or the heat shield s on the exhaust system. The heat of
the exhaust system or the engine could cause them to ignite! This is a fire
hazard.

Cleaning and caring for your vehicle
188Cleaning 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 treatment at the factory.
Good corrosion protection is particularl y important in winter when the car is
frequently driven on salted roads. To prevent the salt corroding the vehicle,
the entire engine compartment should be thoroughly cleaned before and
after the salting period.
Your Authorised Service Centre is able to provide the correct cleaning and
preserving products and has the necessary equipment. For this reason, we
recommend having this work performed by them.
The anti-corrosion protection is usually removed if the engine compartment
is cleaned with grease removing solutions, or if you have the engine cleaned.
If this job is carried out, you should ensure that all surfaces, seams, joints and
components in the engine compartmen t are given anti-corrosion treatment
afterwards.
WARNING
•
When working in the engine compartment, always observe the safety
warnings ⇒ page 198.
•
Switch off the engine, apply the parking brake firmly and always
remove the key from the ignitio n before you open the bonnet.
•
Allow the engine to cool before you clean the engine compartment.
• Do not c l ean the underside of vehicle wheel arches without protecting
your hands and arms. You may cut your self on sharp-edged metal parts.
Failure to comply could result in injury.
•
Moisture, ice and salt on the brakes may affect braking efficiency. Risk
of accident. If possible, avoid sudden braking immediately after washing
the vehicle.
•
Never touch the radiator fan. It is temperature-controlled and could
start automatically, even when the key is removed from the ignition!For the sake of the environment
Fuel, grease and oil deposits could be removed when the engine is washed.
The polluted water must be cleaned in an oil separator. For this reason,
engine washing should be carried out only by a qualified workshop or a suit-
able filling station.Care of the vehicle interiorCleaning plastic parts and the dash panel– Use a clean, damp cloth to clean plastic parts and the dash panel.
– If this does not provide satisfactory results, use a special solvent-free plastic cleaning product.
WARNING
Never clean the dash panel and surface of the airbag module with cleaners
containing solvents. Solvents cause the surface to become porous. If the
airbag inflates, disintegrating plastic parts can cause substantial injuries.

Caution
Cleaning products which contain solvents will damage the material.Cleaning wooden trim*– Clean the wooden trim with a clean cloth moistened with water.
– If this does not provide satisfactory results, use a gentle soap
solution.
CautionCleaning products which contain solvents will damage the material.Cleaning cloth seat covers and fabric trimCloth seat covers and fabric trim on the doors, headlining etc. can be cleaned
with a special interior cleanser or with dry foam and a soft brush.Cleaning leather*Normal cleaning
– Moisten a cotton or woollen cloth with water and wipe over the leather surfaces. Cleaning stubborn stains
– More stubborn dirt can be removed using a mild soap solution
(pure liquid soap; two tablespoons diluted in one litre of water)
and a cloth.
– Do not let the water soak through the leather or soak into the seams.
– Then wipe off with a soft, dry cloth.
Leather care
– The leather should be treated regularly (about twice a year) with a special leather-care product, which is available from your
Authorised Service Centre.
– Apply these products very sparingly.
– Then wipe off with a soft, dry cloth.
SEAT does everything possible to preserve the special qualities of leather, as
a natural product. Because of the natural properties of the specially selected
hides employed, the finished leather has a certain sensitivity to grease and
dirt, etc. so a degree of care is required in everyday use and when looking
after the leather.
Dust and grit in the pores and seams can scratch and damage the surface. If
the vehicle is left standing in the sun for long periods, the leather should be
protected against direct su nlight to prevent it from fading. However, slight
colour variations in high-quality natural leather are normal.
Caution
•
Do not use solvents, wax polish, shoe cream, spot removers or similar
products on leather.

Accessories, parts replacement and modificationsAccessories and partsAlways consult an Authorised Service Centre before
purchasing accessories and parts.Your vehicle is designed to offer a high standard of active and passive safety.
Before purchasing accessories and parts, and before making technical
changes to your car, we recommend that you consult your Authorised Service
Centre.
SEAT dealerships will be happy to provide you with the latest information
about the use, legal requirements and recommendations from the manufac-
turer regarding accessories and parts.
We recommend you use only SEAT Approved Accessories
® and SEAT
Approved Spare Parts
®. This way, SEAT can guarantee that the product in
question is suitable, reliable and safe. Authorised Service Centres have the
necessary experience and facilities to ensure that parts are installed correctly
and professionally.
Despite continuous observation of the market, SEAT is not able to assess the
reliability, safety and suitability of parts not approved by SEAT. For this reason
SEAT cannot assume responsibility for any non-genuine parts used, even if
these parts have been approved by an official testing agency or are covered
by an official approval certificate.
Any equipment subsequently installed which has a direct effect on the
vehicle and/or the way it is driven (e.g. cruise control system or electronically-
controlled suspension) must be approved by SEAT for use in your vehicle and
bear the e mark (the European Union's authorisation symbol).
If any additional electrical components are fitted which do not serve to
control the vehicle itself (for instance a refrigerator box, laptop or ventilator fan, etc.), these must bear the
CE mark (European Union manufacturer
conformity declaration).
WARNING
Accessories, for example telephone holders or drink holders, should never
be fitted on the covers of, or within the working range of, the airbags. If
they are, there is a danger of resulting injury if the airbag is triggered in an
accident.ModificationsModifications must always be carried out according to our
specifications.Unauthorised modifications to the electr onic components or software in the
vehicle may cause malfunctions. Due to the way the electronic components
are linked together in networks, other systems may be affected by the faults.
This can seriously impair safety, lead to excessive wear of components, and
also invalidate your vehicle registration documents.
SEAT Authorised Service Centres cannot be held liable for any damage
caused by modifications and/or work performed incorrectly.
For this reason, we recommend that all work should be performed by an
Authorised Service Centre using genuine and SEAT
® approved parts and
accessories .

Fitting a towing bracket•
Driving with a trailer implies additional work for the vehicle. Therefore,
before fitting a towing bracket, please contact an Authorised Service Centre
to check whether your cooling system needs modification.
•
Observe the legal requirements in your country (e.g. the fitting of a sepa-
rate warning lamp).
•
Certain vehicle components, e.g. the rear bumper must be removed and
reinstalled. The towing bracket securin g bolts must be tightened using a
torque wrench, and an electrical sock et must be used to connect to the
vehicle's electrical system. This requ ires specialist knowledge and tools.
•
The figures in the illustration show the dimensions and attachment points
that must be observed if you are retrofitting a towing bracket.
WARNING
Towing brackets should be fitted by specialists.
•
If the towing bracket is incorrectly installed, there is serious danger of
an accident.
•
For your own safety, please observe the instructions provided by the
manufacturer of the towing bracket.Caution
•

− Never fill the spare fuel canister inside the vehicle or on it. An elec-
trostatic charge could build up during filling, causing the fuel fumes to
ignite. This may be fatally explosive. 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 metal, the filling nozzle must be
in contact with the canister during filling. This helps prevent an electro-
static 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. An irregular fuel supply could cause
misfiring. As a result, unburnt fuel could enter the catalytic converter and
cause damage.For the sake of the environment
Do not try to put in more fuel after the automatic filler nozzle has switched off;
this may cause the fuel to overflow if it becomes warm.
PetrolPetrol types
The correct petrol 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 Norm”).
Petrol types are categorised according to their octane number, e. g. 91, 95,
98 RON (RON = “research octane number”). You may use petrol with a higher
octane number than the one recommended for your engine. However, this
has no advantage in terms of fuel consumption and engine power.
Caution
•
Even one full tank 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 filling with fuel ⇒page 195.RME fuel*
Only those vehicles fitted with special equipment (number PR
2G0 for biodiesel use) may use biodiesel corresponding to
the standard DIN EN 14214.The biodiesel fuel must comply wit h the DIN EN 14.214 (FAME) Standard.•
Biodiesel is a methylester obtained from rapeseed oil.
•
DIN is a German abbreviation for “Deutsches Institut für Normung e.V.”,
the German standards institute.
•
EN means European Norm.
•
FAME is the English abbreviation “ Fatty Acid Methyl Ester” If the date sticker of the vehicle in
cludes the number PR 2G0 optional equip-
ment) this means that that vehicle has been prepared for biodiesel use.
Your Authorised Service Centre or automobile association will be able to
advise on where you can obtain RME biodiesel fuel.
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 can be used in winter at temperatures down to approx. -10°C.
•
At outside temperatures below -10°C, we recommend using winter diesel
fuel.Caution
•
RME fuel can damage the fuel system in vehicles that 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 me et the required standard, the fuel
filter could become clogged.Note
•
In case of low exterior temperatures and a biodiesel fuel 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 that, about every 300 or 400 km, following a fuel
change, also change the fuel filter. Also. note the instructions in the inspec-
tion and maintenance plan.

Checking and refilling levels
198•
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!
