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. 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 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 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.
CAUTION
● 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 194. 
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
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 products) with diesel fuel. Working in the engine compartment
Safety 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 lever 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 202.
You should not do any work in the engine compartment unless you know ex-
actly how to carry out the jobs and have the correct tools! Have the work car-
ried out by a specialised workshop if you are uncertain.
All service fluids and consumables, e.g. coolant, engine oil, spark plugs
and batteries, are under constant development. SEAT provides a constant
flow of information to the Technical Services concerning modifications. For
this reason, we recommend you to have service fluids and consumables re-
placed by a Technical Service. Please observe the relevant instructions
⇒ page 190. The engine compartment of the vehicle is a hazardous area.

Checking and refilling levels
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. Otherwise, there is a risk of sustaining
burns. Wait until no more steam or coolant is emitted, then allow the en-
gine 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 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 coolant expansion tank when the en-
gine 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.WARNING (Continued)
● 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 trap-
ped in rotating engine parts. Danger of death. Before starting any
work remove jewellery, tie back and cover hair, and wear tight-fitting
clothes.
– Never accelerate with a gear engaged without taking the necessary
precautions. The vehicle could move, even if the handbrake is ap-
plied. Danger of death.
● If work has to be carried out on the fuel system or on electrical com-
ponents, you must observe the following safety notes in addition to the
above warnings:
–Always disconnect the battery from the on-board network. The ve-
hicle 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! 

If the windscreen wipers smear , they should be replaced if they are dam-
aged, or cleaned if they are soiled.
If this does not produce the desired results, the setting angle of the wind-
screen wiper arms might be incorrect. They should be checked by a special-
ised workshop and corrected if necessary.
WARNING
Do not drive unless you have good visibility through all windows!
● Clean the windscreen wiper blades and all windows regularly.
● The wiper blades should be changed once or twice a year.
CAUTION
● Damaged or dirty windscreen wipers could scratch the windscreen.
● Never use fuel, nail varnish remover, paint thinner or similar products to
clean the windows. This could damage the windscreen wiper blades.
● Never move the windscreen wiper or windscreen wiper arm manually.
This could cause damage.
● To avoid damage to the bonnet and the windscreen wiper arms, the lat-
ter should only be lifted off the windscreen when in service position.
Note
● The windscreen wiper arms can be moved to the service position only
when the bonnet is properly closed.
● You can also use the service position, for example, if you want to fix a
cover over the windscreen in the winter to keep it clear of ice. 

WARNING (Continued)
● Fires, sparks, open flames and smoking are prohibited. When han-
dling cables and electrical equipment, avoid causing sparks and electro-
static charge. Never short the battery terminals. High-energy sparks can
cause injury.
● A highly explosive mixture of gases is released when the battery is
under charge. The batteries should be charged in a well-ventilated room
only.
● Keep children away from acid and batteries.
● Before working on the electrical system, you must switch off the en-
gine, the ignition and all consumers. The negative cable on the battery
must be disconnected. When a light bulb is changed, you need only
switch off the light.
● Deactivate the anti-theft alarm by unlocking the vehicle before you
disconnect the battery! The alarm will otherwise be triggered.
● When disconnecting the battery from the vehicle on-board network,
disconnect first the negative cable and then the positive cable.
● Switch off all electrical consumers before reconnecting the battery.
Reconnect first the positive cable and then the negative cable. Never re-
verse the polarity of the connections. This could cause an electrical fire.
● Never charge a frozen battery, or one which has thawed. This could
result in explosions and chemical burns. Always replace a battery which
has frozen. A flat battery can freeze at temperatures around 0°C.
● Ensure that the vent hose is always connected to the battery.
● Never use a defective battery. This could cause an explosion. Replace
a damaged battery immediately.
● For vehicles with the battery in the luggage compartment: Check that
the battery gas ventilation hose is securely attached.CAUTION
● Never disconnect the battery if the ignition is switched on or if the en-
gine is running. This could damage the electrical system or electronic com-
ponents.
● Do not expose the battery to direct sunlight over a long period of time,
as the intense ultraviolet radiation can damage the battery housing.
● If the vehicle is left standing in cold conditions for a long period, protect
the battery from freezing. If it freezes it will be damaged. 
Checking the electrolyte level
The electrolyte level should be checked regularly in high-
mileage vehicles, in hot countries and in older batteries. – Open the engine bonnet and the battery cover ⇒ 
in Safety in-
structions on working in the engine compartment on page 201
⇒ 
in Warnings on handling the battery on page 214.
– Check the colour display in the "magic eye" on the top of the
battery.
– If there are air bubbles in the window, tap the window gently
until they disperse.
The position of the battery is shown in the corresponding engine compart-
ment diagram ⇒ page 259.
The “magic eye” indicator, located on the top of the battery changes colour,
depending on the charge state and electrolyte level of the battery.
There are two different colours: 

For the sake of the environment
Please ask your specialist retailer how to dispose of used bulbs in the prop-
er manner.
Note
● Depending on weather conditions (cold or wet), the front lights, the fog
lights, the tail lights and the turn signals may be temporarily misted. This
has no influence on the useful life of the lighting system. By switching on
the lights, the area through which the beam of light is projected will quickly
be demisted. However, the edges may continue to be misted.
● Please check at regular intervals that all lighting (especially the exterior
lighting) on your vehicle is functioning properly. This is not only in the inter-
est of your own safety, but also that of all other road users.
● Before changing a bulb, make sure you have the correct new bulb.
● Do not touch the glass part of the bulb with your bare hands, use a cloth
or paper towel instead. Otherwise, the fingerprints left on the glass will va-
porise as a result of the heat generated by the bulb, they will be deposited
on the reflector and will impair its surface. 
1)
With this type of headlight, the user can replace the turn signal bulb. Replacement of the
dipped/main beam bulb must be done by a Technical Service, given that complex elements
must be removed from the vehicle and the automatic control system that incorporates it
must be reset.
2) The Xenon bulbs discharge 2.5 times the light flux and have an average lifespan of 5 times
more than that of halogen bulbs, this means that, except due to unusual circumstances,
there is no need to change the bulbs for the whole life of the vehicle.
3) In the event that there is a fault in the LEDs, the complete headlight must be replaced.
