Checking and refilling levels
●
When filling the fuel tank after having run it
completely dry on a vehicle with a diesel en-
gine the ignition must be switched on for at
least 30 seconds before starting the engine.
Subsequently, when you start the engine it
may take longer than normal to start firing
(up to one minute). This is due to the fact that
the fuel system has to purge itself of air be-
fore starting. For the sake of the environment
Do not try to put in more fuel after the auto-
matic filler nozzle has switched off; this may
cause the fuel to overflow if it becomes warm. 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
c at
alytic converters (EN = “European Stand-
ard”).
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. How- ever, this has no advantage in terms of fuel
consumption and engine power. CAUTION
● Petrol with standard EN 228 may be mixed
with small quantities of ethanol. However,
the so-called “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 per-
manently impair the efficiency of the catalyt-
ic 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 seri-
ously impair the efficiency of the catalytic
converter. Petrol additives
The quality of the fuel influences the behav-
iour, power and service life of the engine.
This is why the petrol you use should carry
suitable additives already included by the
petrol industry, free of metals. These addi-
tives will help to prevent corrosion, keep thefuel system clean and prevent deposits from
building up in the engine.
If good-quality petrol with metal-free addi-
tives 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 unsuitable petrol ad-
ditives may cause significant damage to the
engine and the catalytic converter. Metal ad-
ditives should never be used. Metal additives
may also be contained in petrol additives for
improving anti-detonation ratings or octane
ratings.
SEAT recommends “genuine Volkswagen
Group fuel additives for petrol engines”.
These additives can be bought at SEAT Au-
thorised 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 replacement
petrol) fuels contain high concentrations of
metal additives. Using them may damage the
engine! 159

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 num-
ber indicates the ignition quality of the diesel
fuel.
Notes on refuelling ››› page 158.
Biodiesel* CAUTION
● Your vehicle is not designed to use biodie-
sel fuel. Never, under any circumstances re-
fuel with biodiesel. The use of biodiesel fuel
could damage the engine and the fuel sys-
tem. The addition of biodiesel to diesel fuel
by the diesel manufacturer in accordance
with standard EN 590 or DIN 51628 is author-
ised 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 pet-
rol, 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 specialised per-
sonnel. The composition of these fuels may
severely damage the fuel system and the en-
gine. Winter operation
Winter-grade diesel
When using “summer-grade diesel fuel”, dif-
ficulties may be experienced at temperatures
below 0 °C (+32 °F) because the fuel thickens
due to wax separation. For this reason, “win-
ter-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 die-
sel fuels available.
Filter pre-heater
Your vehicle is fitted with a fuel filter glow
plug system, making it well equipped for op-
eration 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 ex-
tent that the engine will not start at tempera-
tures of under -24 °C (-11 °F), simply leave
the vehicle in a heated area for a while.
CAUTION
Do not mix fuel additives, the so-called “thin-
ners”, or similar additives with diesel fuel. LPG system (Liquefied
petroleum gas)*

››› .
Read carefully the instructions on how to use
the LPG pump.
Opening the fuel tank cap
The LPG filler neck is behind the fuel cap,
next to the petrol filler neck.
● The tank flap is located on the rear right-
hand side of the vehicle.
● Open the fuel tank flap.
Refuelling
● Remove the plug from the gas filler mouth
››› Fig. 140 1 .
● Screw the required adapter 2 onto the
LPG gas filler neck. ●
Refuel as indicated in the pump instruc-
tions.
● The fuel tank will be full when the pump
c ompr
essor automatically cuts the supply.
● If you wish to finish refuelling sooner, re-
lease the button on the pump to stop the
flow.
Closing the fuel tank cap
● Unscrew the adapter from the gas filler
neck 2 .
● Screw the cap onto the gas filler neck 1 .
● Close the fuel tank flap. The cover should
be flush with the bodywork. WARNING
Incorrect handling of LPG can cause explo-
sions, fire, serious burns and other injuries.
● LPG is a highly explosive and inflammable
substance.
● Small quantities of LPG may leak out after
refuelling. If LPG comes into contact with the
skin there is a risk of freezing. Note
● The vehicle includes one adapter for the
country in question, the most common one.
We generally recommend that you carry all
the adapters in your vehicle, as some coun-
tries use more than one type of filling sys-
tem. ●
If the outside temperature is very high, the
protection against overheating for the LPG
pump may disconnect automatically.
● If the outside temperature is very high, the
pressure of the LPG tank may be equal to or
greater than that of the gas tank of the LPG
pump. In this case, refuelling will be physi-
cally impossible.
● The filling nozzles of LPG pumps can differ
in the way they are operated. If you do not
know, ask a qualified employee at the petrol
station to do the refuelling.
● Noises heard when refuelling are normal
and do not indicate the presence of a fault in
the system. 161

Checking and refilling levels
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 propor-
tion of propane gas. As a result, the driving
range of winter gas may be lower (due to in-
creased consumption) than that of summer
gas.
LPG supplier network
The number of LPG pumps is constantly in-
creasing.
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 con-
firmed its high level of safety.
The safety of the LPG system guarantees op-
eration 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 interior.
● All anchorage points and materials have
been designed to ensure the maximum pos-
sible 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 immediately 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 vehi-
cle must check that these services are per-
formed correctly. ●
When parking the vehicle in a closed area
(e.g. in a garage), make sure that there is ad-
equate 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 work-
shops authorised to repair these faults. Working in the engine
compartment

Advice
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 specialised
workshop if you are uncertain.
All service fluids and consumables, e.g. cool-
ant, engine oil, spark plugs and batteries,
are under constant development. SEAT pro-
vides a constant flow of information to Tech-
nical Services concerning modifications. For
this reason, we recommend you have service
fluids and consumables replaced by a Techni-
cal Service. Please observe the relevant in-
structions ››› page 147 . The engine compart-
ment of
the vehicle is a hazardous area.
››› .
WARNING
All work on the engine or in the engine com-
partment, e.g. checking and refilling fluids,
involves the danger of injury and burns, acci-
dents and even 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
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 electri-
cal system, particularly at the points where
the jump leads are attached ››› page 190. The
battery could explode.
● Never touch the radiator fan. It is tempera-
ture controlled and could start automatically,
even when the engine has been switched off
and the key removed from the ignition!
● Never cover the engine with additional in-
sulating materials such as a blanket. Risk of
fire!
● Do not unscrew the cap on the coolant ex-
pansion 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 ob-
jects, such as cleaning cloths or 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 acci-
dent!. A hydraulic jack is insufficient for se-
curing 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:
– 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-fit-
ting clothes.
– Never accelerate with a gear engaged
without taking the necessary precau-
tions. 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 components, you
must observe the following safety notes in
addition to the above warnings:
– Always disconnect the battery from the
on-board network. 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 topping up service fluids, make sure
not to mistake them. Using the wrong fluids
could cause serious malfunctions and engine
damage! 164

Checking and refilling levels
For the sake of the environment
Service fluids leaks are harmful to the envi-
ronment. For this reason you should make
regular checks on the ground underneath
your vehicle. If you find spots of oil or other
fluids, have your vehicle inspected in a speci-
alised workshop. Opening the bonnet

so it locks.
If the bonnet does not close, do not press
downwards. Open it once more and let it fall
as before. WARNING
If the bonnet is not closed properly, it could
open while you are driving and completely
obscure your view of the road. Risk of acci-
dent.
● After closing the bonnet, always check that
it is properly secured. The bonnet must be
flush with the surrounding body panels.
● If you notice that the bonnet latch is not se-
cured when the vehicle is moving, stop the

En gine oi
l
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 essen-
tial for the correct operation of the engine
and its long useful life, when topping up or
changing oil, use only those oils that comply
with VW standards.
The specifications (VW standards) set out on
the following page should appear on the con-
tainer 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 Programme be performed
by a technical service or a specialised work-
shop.
The correct oil specifications for your engine
are listed in the
›››
page 167, Oil properties .Service intervals
Service intervals can be flexible (LongLife
service) or fixed (dependent on time/dis-
tance travelled).
If the PR code that appears on the back of the
Maintenance Programme booklet is PR QI6,
this means that your vehicle is programmed
with the LongLife service. 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 devel-
oped which, depending on characteristics
and individual driving profiles, allow for
greater intervals between oil change services
(LongLife service intervals).
Because this oil is essential for extending the
service intervals, it
must only be used ob-
serving the following indications:
● Avoid mixing it with oil for fixed service in-
tervals.
● Only in exceptional circumstances, if the
engine oil level is too low ››› page 167 and
LongLife oil is not available, it is permitted to
top up (once) with oil for fixed service inter-
vals › ›
›
page 167 (up to a maximum of 0.5 li-
tres).
166

Checking and refilling levels
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 also appear in
›
› › page 167,
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 Pro-
gramme.
● In ex

ceptional circumstances, if the engine
oil level is too low ››› page 167 and you can-
not o

btain the oil specified for your vehicle,
you can put in a small quantity of oil con-
forming 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 a 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 diesel engines
equipped with particulate filter. Using other
types of oil will cause a higher soot concen-
tration and reduce the life of the DPF. There-
fore:
● Avoid mixing this oil with other engine oils.
● Only in exceptional circumstances, if the
engine oil level is too low ››› page 167 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).

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 correspond-
ing VW specifications and recommend keep-
ing it in the vehicle. This way, the correct en-
gine oil will always be available for a top-up if
needed. Checking the engine oil level

Checking oil level
– Park the vehicle in a horizontal position.
– Briefly run the engine at idle speed until
the operating temperature is reached and
then stop.
– Wait for about two minutes.
