Vehicle maintenance and cleaning
The longer stains or dirt remain on the vehicle surfaces, especially the fab-
rics covering the padded upholstery, the more difficult it becomes to clean
and maintain them. If stains and dirt are left for a long time, it may be that
they are impossible to remove.
WARNING
Car-care products may be toxic and hazardous. Using unsuitable car-care
products or, using them in the wrong way, may cause accidents, serious
injury, burns or intoxication.
● Keep your car-care products in their original containers.
● Read the instructions.
● Never keep car-care products in empty food containers, bottles or
other similar containers, other people may confuse them.
● Keep all car-care products out of the reach of children.
● Some products may give off harmful vapours during use. Therefore,
they should be used outdoors in well-ventilated places.
● Never use fuel, turpentine, engine oil, nail-varnish remover or any
other volatile product for washing, maintenance or cleaning. These are
toxic and highly flammable.
WARNING
Unsuitable maintenance and cleaning of vehicle components may impair
proper operation of safety equipment and cause serious injury.
● Maintain and clean vehicle components according to the manufactur-
er's instructions.
● Only use approved or recommended cleaning products.
CAUTION
● Cleaning products which contain solvents have a corrosive effect and
may damage the material irreparably.
● Stains and dirt containing aggressive substances or solvents attack the
material and may damage it irreparably, even when they are cleaned quick-
ly.
● Dirt and stains should not be allowed to dry and should be cleaned as
quickly as possible.
● In the case of stubborn stains, take the vehicle to a specialised work-
shop to avoid damage. 
Treating your upholstery
Checklist
To treat and maintain your seat upholstery, keep the following in mind ⇒ 
:
¥ Before entering the vehicle, close any Velcro fasteners that might
snag on the upholstery or trim fabric. Any open Velcro fasteners may
damage the trim or upholstery fabrics.
¥ To prevent damage, avoid direct contact between sharp decorative
objects and the upholstery and trim fabrics. Decorative objects in-
clude zips, rivets and rhinestones on clothing and belts.
¥ From time to time, clean the dust that gathers in the perforations,
folds and seams so that the surfaces of the seats are not damaged
by its abrasive effect.
¥ Make sure clothes are colour-fast to avoid them running and staining
the upholstery. This is especially important if the upholstery is light
in colour.

Refuelling
The tank flap is released manually. The tank holds approxi-
mately 55 litres.
Fig. 156 Tank flap open
Opening the fuel tank cap
– Lift the lid.
– Hold the cap firmly with one hand, then insert the key into the
lock and rotate 180° to the left.
– Unscrew the cap, turning it anticlockwise.
Closing the fuel tank cap
– Screw the tank cap to the right, until the point of feeling a
“click”. –
Turn the key in the lock, without releasing the cap, clockwise
through 180°.
– Remove the key and close the flap until it clicks 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 fuel 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.
The correct fuel grade for your vehicle is given on a sticker on the inside of
the fuel tank flap. Here you will find further information on fuel. 

WARNING
● Fuel is highly flammable and can cause serious burns and other inju-
ries.
–Never smoke or use an open flame when filling the fuel tank of the
vehicle, or a spare fuel canister, with fuel. This is an explosion haz-
ard.
– Follow legal requirements for the use of spare fuel canisters.
– For safety reasons we do not recommend carrying a spare fuel can-
ister in the vehicle. The canister could be damaged in an accident and
leak.
● If, in exceptional circumstances, you have to carry a spare fuel canis-
ter, 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 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 possi-
ble.
– 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
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. 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. 

.
– Close the fuel tank flap.
When the hose is removed from the tank, a small amount of LPG may spill
out ⇒ 
.
The LPG tank ⇒ Fig. 158 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 switch off mobile phones and any other radiophony applian-
ces, 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.
WARNING (Continued)
● Small quantities of LPG may leak out after refuelling. If LPG comes in-
to 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.

Adapter 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. 159 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 1
,
the Dish Coupling 2, the bayonet 3 or the EURO adapter 4.
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. 1
234
Note
The four most common types of adapter in Europe are the ACME adapter 1,
the Dish Coupling adapter 2, the bayonet adapter 3 and the EURO adapt-
er 4. On the whole, we recommend you carry all four adapters in your vehi-
cle, as some countries use more than one type of filling system. The intro-
duction of a single system (Euronozzle) throughout Europe is being studied. 
LPG fuel
LPG 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
emissions. Compared to other fossil fuels, LPG is characterised by its re-
duced emissions.
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 safety
A series of collision tests performed on this vehicle while running with LPG
have confirmed its high level of safety. 

231
Checking and refilling levels
The safety of the LPG system guarantees operation without risk. The follow-
ing 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
immediately if gas is smelt or a leak is detected.
● LPG tanks are subject to pressure and must be checked regularly. The
owner of the vehicle must check that these services are performed cor-
rectly.
● When parking the vehicle in a closed area (for example in a garage),
make sure that there is adequate ventilation, either natural or mechani-
cal, to neutralise the LPG in the event of a leak.
Note
For any fault in the LPG system, please refer to the SEAT web page, which
lists the workshops authorised to repair these faults. Petrol
Petrol 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 rec-
ommended 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 etha-
nol. However, 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.
● 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 oc-
cur, the required additives must be added during refuelling. 
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 number indi-
cates the ignition quality of the diesel fuel.
Notes on refuelling ⇒ page 226. Biodiesel*
CAUTION
● Your vehicle is not designed to use biodiesel fuel. Never, under any cir-
cumstances 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
fuel conforming to standard EN 590. 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 speci-
alised personnel. The composition of these fuels may severely damage the
fuel system and the engine. 
Winter driving
Diesel can thicken in winter.
Winter-grade diesel
When using “summer-grade diesel fuel”, difficulties may be experienced at
temperatures below 0 °C 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 the Technical Services
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 glow plug system, making it well
equipped for operation in winter. This ensures that the fuel system remains 
