Petrol additives
Petrol additives improve the quality of the petrol.
The quality of the fuel influences the behaviour, performance and service
life of the engine.
This is why the petrol you use should carry suitable additives already inclu-
ded by the petrol industry, free of metals. These additives will help to pre-
vent corrosion, keep the fuel system clean and prevent deposits from build-
ing up in the engine.
If good-quality petrol with metal-free additives 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 unsuita-
ble petrol additives may cause significant damage to the engine and the
catalytic converter. Metal additives should never be used. Metal additives
may also be contained in petrol additives for improving anti-detonation rat-
ings or octane ratings.
SEAT recommends “genuine Volkswagen Group fuel additives for petrol en-
gines”. These additives can be bought at SEAT Authorised Services, 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 re-
placement petrol) fuels contain high concentrations of metal additives. Us-
ing 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 number indi-
cates the ignition quality of the diesel fuel.
Notes on refuelling ⇒ page 228. 
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 (+32 °F) because the fuel thickens due to wax sep-
aration. 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 (-8 °F).
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 (-11 °F), provided you use winter-grade diesel
which is safe to -15 °C (+5 °F).
However, if the fuel has waxed to such an extent that the engine will not
start at temperatures of under -24 °C (-11 °F), 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 237.
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 226. The engine compartment of the 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. 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 288. 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! 

moving, stop the vehicle immediately and close the bonnet properly.
Risk of accident.
 Engine oil
General notes
The engine comes with a special, multi-grade oil that can be used all year
round.
Because the use of high-quality oil is essential for the correct operation of
the engine and its long useful life, when topping up or changing oil, use on-
ly those oils that comply with VW standards.
The specifications (VW standards) set out in the following page should ap-
pear on the container of the service oil; when the container displays the
specific standards for petrol and diesel engines together, it means that the
oil can be used for both types of engines.
We recommend that the oil change, indicated in the Maintenance Pro-
gramme, be performed by a Technical Service or a specialised workshop.
The correct oil specifications for your engine are listed in the ⇒ page 239,
Oil properties.
Service intervals
Service intervals can be flexible (LongLife service) or fixed (dependent on
time/distance travelled).
If the PR code that appears on the back of the “Maintenance Programme”
booklet is PR QI6, this means that your vehicle has the LongLife service pro-
grammed. If it lists the codes QI1, QI2, QI3, QI4 or QI7, the interval service
is dependent on time/distance travelled.
Flexible service intervals (LongLife service intervals*)
Special oils and processes have been developed which, depending on the
characteristics and individual driving profiles, enable the extension of the
oil change service (LongLife service intervals). 

239
Checking and refilling levels
Because this oil is essential for extending the service intervals, it must only
be used observing the following indications:
● Avoid mixing it with oil for fixed service intervals.
● Only in exceptional circumstances, if the engine oil level is too low
⇒ page 240 and LongLife oil is not available, it is permitted to top up
(once) with oil for fixed service intervals ⇒ page 239 (up to a maximum of
0.5 litres).
Fixed service intervals*
If your vehicle does not have the “LongLife service interval” or it has been
disabled (by request), you may use oils for fixed service intervals, which al-
so appear in ⇒ page 239, Oil properties. In this case, your vehicle must be
serviced after a fixed interval of 1 year/15 000 km (10 000 miles)(whatever
comes first) ⇒ Booklet Maintenance Programme.
● In exceptional circumstances, if the engine oil level is too low
⇒ page 240 and you cannot obtain the oil specified for your vehicle, you
can put in a small quantity of oil conforming to the specification ACEA A2 or
ACEA A3 (petrol engines) or ACEA B3 or ACEA B4 (diesel engines) (up to 0.5
l).
Vehicles with diesel particulate filter*
The “Maintenance Programme” states whether your vehicle is fitted with a
diesel particulate filter.
Only VW 507 00 engine oil, with reduced ash formation, may be used in die-
sel engines equipped with particulate filter. Using other types of oil will
cause a higher soot concentration and reduce the life of the DPF. Therefore:
● Avoid mixing this oil with other engine oils.
● Only in exceptional circumstances, if the engine oil level is too low
⇒ page 240 and you cannot obtain the oil specified for your vehicle, you
can use a small quantity of oil (once) conforming to the VW 506 00,
VW 506 01, VW 505 00, VW 505 01 or ACEA B3/ACEA B4 specification. (up
to 0.5 l). Oil properties

Engine oil additives
No type of additive should be mixed with the engine oil. The deterioration
caused by these additives is not covered by the warranty.
Note
Before a long trip, we recommend finding an engine oil that conforms to the
corresponding VW specifications and recommend keeping it in the vehicle.
This way, the correct engine oil will always be available for a top-up if nee-
ded. 

compartment: Engine oil
filler cap
Before opening the bonnet, read and observe the warnings ⇒ 
in
Safety instructions on working in the engine compartment on
page 235.
– Unscrew cap from engine oil filler opening ⇒ Fig. 167.
– Top-up oil in small amounts, using the correct oil.
– To avoid over-filling with engine oil, you should top-up using
small quantities, wait a while and check the oil level before
adding any more oil.
– As soon as the oil level is in area B
, carefully close the cap.
The position of the oil filler opening is shown in the corresponding engine
compartment illustration ⇒ page 297.
Engine oil specification ⇒ page 238.
WARNING
Oil is highly inflammable! Ensure that no oil comes into contact with hot
engine components when topping up.
CAUTION
If the oil level is above the area A do not start the engine. This could result
in damage to the engine and catalytic converter. Contact a specialised work-
shop.
For the sake of the environment
The oil level must never be above area A. Otherwise oil can be drawn in
through the crankcase breather and escape into the atmosphere via the ex-
haust system. 
Changing engine oil
The engine oil must be changed at the intervals given in the
service schedule. We recommend that you have the engine oil changed by a Technical Serv-
ice.
The oil change intervals are shown in the Maintenance Programme. 

WARNING
Only change the engine oil yourself if you have the specialist knowledge
required!
● Before opening the bonnet, read and observe the warnings
⇒ page 235, Safety instructions on working in the engine compartment.
● Wait for the engine to cool down. Hot oil may cause burn injuries.
● Wear eye protection to avoid injuries, such as acid burns, caused by
splashes of oil.
● When removing the oil drain plug with your fingers, keep your arm
horizontal to help prevent oil from running down your arm.
● Wash your skin thoroughly if it comes into contact with engine oil.
● Engine oil is poisonous! Used oil must be stored in a safe place out of
the reach of children.
CAUTION
No additives should be used with engine oil. This could result in engine
damage. Any damage caused by the use of such additives would not be
covered by the factory warranty.
For the sake of the environment
● Because of the disposal problems, the necessary special tools and spe-
cialist knowledge required, we recommend that you have the engine oil and
filter changed by a Technical Service.
● Never pour oil down drains or into the ground.
● Use a suitable container when draining the used oil. It must be large
enough to hold all the engine oil. Coolant
Engine coolant specifications
The engine cooling system is supplied from the factory with a specially trea-
ted mixture of water and, at least, 40 % of the additive G 13 (TLVW 774 J).
The engine coolant additive is recognisable by its purple colour. This mix-
ture of water and additive gives the necessary frost protection down to
-25°C (-13 F) and protects the light alloy parts of the cooling system against
corrosion. It also prevents scaling and considerably raises the boiling point
of the coolant.
To protect the engine cooling system, the percentage of additive must al-
ways be at least 40 %, even in warm climates where anti-freeze protection is
not required.
If greater frost protection is required in very cold climates, the proportion of
additive can be increased. However, the percentage of additive should not
exceed 60 %, as this would reduce the frost protection and, in turn, de-
crease the cooling capacity.
When the coolant is topped up, use a mixture of distilled water and, at
least, 40 % of the G 13 or G 12 plus-plus (TL-VW 774 G) additive (both are
purple) to obtain an optimum anticorrosion protection ⇒ 
. The mixture of
G 13 with G 12 plus (TL-VW 774 F), G 12 (red) or G 11 (green-blue) engine
coolants will significantly reduce the anticorrosion protection and should,
therefore be avoided ⇒

Checking and refilling levels
The windscreen washer and the headlight washers are supplied with fluid
from the windscreen washer fluid container in the engine compartment.
The reservoir is located on the right-hand side of the engine compartment.
Plain water is not enough to clean the windscreen and headlights. We rec-
ommend that you always add a product to the windscreen washer fluid. Ap-
proved windscreen cleaning products exist on the market with high deter-
gent and anti-freeze properties, these may be added all-year-round. Please
follow the dilution instructions on the packaging.
WARNING
Any work carried out in the engine compartment or on the engine must
be carried out cautiously.
● When working in the engine compartment, always observe the safety
warnings ⇒ page 235.
CAUTION
● Never put radiator anti-freeze or other additives into the windscreen
washer fluid.
● Always use approved windscreen cleansing products diluted as per in-
structions. If you use other washer fluids or soap solutions, the tiny holes in
the fan-shaped nozzles could become blocked. Changing windscreen wiper blades
If the windscreen wiper blades are in perfect condition, you
will benefit from an improved visibility. Damaged wiper
blades should be replaced immediately.

To change the blades it is necessary to change the rest position of
the wipers to the service position.
Service position (For changing wiper blades)
–Ensure that the wiper blades are not frozen.
– Turn ignition on and off and then (before approx. 8 seconds
have elapsed), move the windscreen wiper lever to the intermit-
tent wipe position. The windscreen wipers will move to the serv-
ice position.
Changing the windscreen wiper blades
– Lift the wiper arm away from the windscreen.
– Push the side buttons, free the blade and pull in the direction of
the arrow ⇒ Fig. 171
Fitting the wiper blade
– Insert a blade of identical length and design into the wiper arm.
– Slide the blade until it clicks into position.
– Push the wiper arms back against the windscreen.
The windscreen wiper arms return to their original position when the igni-
tion is turned on and the windscreen wiper lever is operated, or when driv-
ing faster than 6 km/h (4 mph).
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.
● Do not pull the windscreen wipers forward unless they are in the service
position. Otherwise the bonnet could be damaged.
Note
● The windscreen wiper arms can be moved to the service position only
when the bonnet is properly closed. 
