Underbody sealant
The vehicle underbody is coated to protect it from chemical
and mechanical damage.The protective coating can be damaged when driving. We recommend you to
check the protective coating under the body and on the running gear, and
reinstated if necessary, before and after the winter season.
We recommend you to go to your Authorised Service Centre to carry out repair
work and additional anti-corrosion work.
WARNING
Do not apply underseal or anti-corrosion coatings to the exhaust pipes,
catalytic converter or the heat shields on the exhaust system. The heat of
the exhaust system or the engine could cause them to ignite! Fire hazard.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 treatment at the factory.
Good corrosion protection is particularly 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 winter.
Yo u r A u t h o r i s e d S e r v i ce Ce n t re has got the necessary equipment to provide
the correct cleaning and preserving products. 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.
On commissioning this work, ensure that all surfaces, seams, joints and
components in the engine compartment are given anti-corrosion treatment.
WARNING
•When working in the engine compartment, always observe the safety
warnings ⇒page 215.•Before opening the bonnet, switch the engine off, apply the parking
brake firmly and always remove the key from the ignition.•Allow the engine to cool before you clean the engine compartment.•Do not clean the vehicle underbody, wheel arches 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 brakes may affect braking efficiency. Risk
of accident. Directly after washing, avoid sudden and sharp braking.•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 petrol
station.

Checking and refilling levels
208Checking and refilling levelsRefuellingThe fuel cap cover opens automatically with the central
locking system. The tank holds approximately 55 litres.Unscrewing the tank cap
– Lift the lid.
– Unscrew the cap, turning it anti-clockwise.
Closing the tank cap
– Screw the tank cap to the right, until the point of feeling a “click”.
– Close the drawer. Make sure you hear it click into place. The tank
cap is secured with an anti-loss attachment
The tank flap is at the rear of the vehicle on the right.
If the automatic filler nozzle is operated correctly, it will switch itself off as
soon as the tank is “full”. Never attempt to fill beyond this point, as this will
fill the expansion chamber. Fuel may leak out if ambient conditions are warm.
T he co rr ec t fu el g rad e fo r you r v eh icle is giv en on a sti cker o n th e i nsid e of the
fuel tank flap. where further notes on fuel can be found.
Releasing the fuel tank flap by hand
If the central locking system fails, the fuel tank flap can be opened manually
as follows:•Open the tailgate•Remove the cover from the right side trim in the luggage compartment.•Insert a hand and pull the locking device back•Open the cap and take out the plug.WARNING
•Fuel is highly inflammable and can cause serious burns and other inju-
ries.
−Never smoke or use any naked flame 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 vehicle. 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 points:

−
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.

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 injury.•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.

212Adapter 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.
The success of LPG is due to the strict regulations concerning exhaust gas

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.

Safety First
Controls and equipment
Practical tips
Technical Data
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 compartment.•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 qualified 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.
PetrolPetrol types
The recommended fuel 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 Standard”).
Fuel types are differentiated by the octane rating, e.g: 91, 95, 98 RON (RON
= “Regulation 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. Section “Technical Data”
Caution
•Petrol that follows EN 228 may be mixed with small quantities of ethanol.
However, the so-called “bioethanol fuels” available at commercial establish-
ments 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.•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.

214Petrol 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 208.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.•RME fuel 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 exterior 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 you that, when having run 300 or 400 km after a
fuel change, the fuel filter change must also be done. Also note the instruc-
tions in the Inspection and Maintenance plan.•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.
Therefore, “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 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.
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 217.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 you to have service fluids and consumables
replaced by an Authorised Service Centre. Please observe the relevant
instructions ⇒page 206. The engine compartment of any motor vehicle is a
hazardous area ⇒.

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. 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 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 264. 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.•Al wa ys m ake s u re yo u ha ve n o t l e f t a ny o bj e c t s , s u ch as cl e an i n g cl o t h s
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 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-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 safety 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!
