Quality requirements for LPG are regulated
for all Europe in DIN EN 589 and permit the
use of LPG throughout Europe without any
problems.
LPG is a mixture of propane and butane.
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.
The vehicle's engine management adapts au-
tomatically to the LPG used. Therefore, both
types of LPG can be mixed in the tank, with-
out the need for comprehensive draining be-
fore applying a different quality LPG. LPG and safety
If you smell gas or suspect that there is a
leak in the LPG system.
››› ●
Stop the vehicle immediately.
● Switch the ignition off.
● Open all the doors to properly ventilate the
vehicle.
● Extinguish cigarettes immediately.
● Move away from the vehicle or switch off
objects that may cause sparks or a fire.
● If you continue to smell gas, do not contin-
ue driving!
● Seek specialist assistance. Have the fault
repaired. WARNING
LPG is a highly explosive and inflammable
substance. It may cause severe burns and
other injury.
● Due care must be taken to avoid any risk of
fire or explosion.
● 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. WARNING
Failure to act when you can smell gas in the
vehicle or when refuelling can cause serious
injuries.
● Carry out the necessary operations.
● Leave the danger zone.
● If necessary, warn the emergency services. Note
● The LPG system must be subject to regular
inspections at a specialised workshop in ac-
cordance with the Maintenance Plan.
● The engine is always started with petrol,
even when LPG was being used when it was
switched off. For this reason the tank should
never be drained of petrol completely.
● If frequent short journeys are made, espe-
cially when the outside temperature is low,
the vehicle will tend to run on petrol more of-
ten than on LPG. Therefore, the petrol tank
may empty before the LPG tank.
● If while driving the system switches auto-
matically to petrol operating mode because
the LPG tank is almost empty, the next few
times the engine starts up, and depending on
the outside temperature and driving style, it
may automatically switch briefly to LPG oper-
ating mode to use up what is left in the tank.
● When the system automatically switches to
petrol operating mode because the LPG tank
is almost empty, you can revert to gas operat-
ing mode by pressing the ››› Fig. 121 GAS »

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

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

LPG f uel LPG is an alternative vehicle fuel and is a
blend of propane and butane.
The success of LPG is due to the strict regula-
tions concerning exhaust gas emissions.
Compared to other fossil fuels, LPG is charac-
terised by its reduced emissions.

Wheels and tyres General notes Avoiding damage
– If you have to drive over a kerb or similar
obstacle, drive very slowly and at a right
angle.
– Keep grease, oil and fuel off the tyres.
– Inspect the tyres regularly for damage
(cuts, cracks or blisters, etc.). Remove any
foreign objects embedded in the treads.
Storing tyres
– When you remove the tyres, mark them in
order to maintain the same direction of ro-
tation when they are installed again.
– When removed, the wheels and/or tyres
should be stored in a cool, dry and prefera-
bly dark location.
– Store tyres in a vertical position if they are
not fitted on wheel rims.
New tyres
New tyres must be run in ›››
page 130.
The tread depth of new tyres may vary, ac-
cording to the type and make of tyre and the
tread pattern. Concealed damage
Damage to tyres and rims is often not readily
visible. If you notice unusual vibrations or the
vehicle pulling to one side, this may indicate
that one of the tyres is damaged. They
should be checked immediately by a Techni-
cal Service.
Tyres with directional tread pattern
An arrow on the tyre sidewall indicates the di-
rection of rotation on tyres with directional
tread. Always observe the direction of rota-
tion indicated when fitting the wheel. This
guarantees optimum grip and helps to avoid
aquaplaning, excessive noise and wear.
WARNING
● New tyres do not have maximum grip dur-
ing the first 500 km (300 miles). Drive partic-
ularly carefully to avoid possible accidents.
● Never drive with damaged tyres. This may
cause an accident.
● If you notice unusual vibrations or if the ve-
hicle pulls to one side when driving, stop the
vehicle immediately and check the tyres for
damage. Checking tyre pressure
The correct tyre pressure can be seen on the
sticker on the inside of the fuel tank flap.1. Read the required tyre inflation pressure
from the sticker. The values refer to Sum-
mer tyres. For winter tyres, you must add
0.2 bar (2.9 psi / 20 kPa) to the values
given for summer tyres.
2. The tyre pressures should only be checked when the tyres are cold. The slightly raised
pressures of warm tyres must not be re-
duced.
3. Adjust the tyre pressure to the load you are carrying.
Tyre pressure
The correct tyre pressure is especially impor-
tant at high speeds. The pressure should
therefore be checked at least once a month
and before starting a journey.
The sticker with the tyre pressure values can
be found on the inside of the fuel tank flap.
The tyre pressure values given are for cold
tyres. Do not reduce the slightly raised pres-
sures of warm tyres ››› .
WARNING
● Check the tyre pressure at least once per
month. Checking the tyre pressure is very im-
portant. If the tyre pressure is too high or too
low, there is an increased danger of accidents
- particularly at high speeds.
● A tyre can easily burst if the pressure is too
low, causing an accident! » 175Technical specifications

Advice
For the sake of the environment
Under-inflated tyres will increase fuel con-
sumption. Run-flat tyres
Run-flat tyres allow you to continue driving
even with a punctured tyre, in the majority of
cases.
In vehicles that are factory-fitted with run-flat
tyres
1)
the loss of tyre pressure is indicated
on the instrument panel.
Driving with run-flat tyres (emergency
running)
– Leave the ESC/ASR on (Electronic Stability
Control), or switch it on ›››
page 137.
– Continue driving carefully and slowly
(80 km/h [50 mph] maximum).
– Avoid sudden manoeuvres and sharp turns.
– Avoid driving over obstacles (e.g. kerbs) or
potholes.
– Pay attention if the ESC/ASR activates of-
ten, if smoke comes from the tyres or there
is a smell of rubber, the vehicle vibrates or
there are clattering noises. If any of these
occur, stop the vehicle. The run-flat tyres have a tag on the side of
the tyre, with the description: “DSST”, “Eufo-
nia”, “RFT”, “ROF”, “RSC”, “SSR” or “ZP”.
The sides of this type of tyre are reinforced.
When the tyres lose air they are supported on
the sides (emergency driving).
The loss of pressure in the tyre is shown on
the instrument panel. You can then drive a
maximum of 80 km (50 miles) and if the cir-
cumstances are favourable (e.g. low load),
even more.
The damaged tyre should be changed as
soon as possible. The rim should be checked
in a specialised workshop to detect possible
damage and replace it if necessary. We rec-
ommend you contact your technical service.
If more than one tyre is being used under
emergency conditions, this reduces the dis-
tance that can be travelled.
Starting driving in emergency conditions
When loss in tyre pressure is displayed on
the instrument panel, this means that at least
one tyre is being driven in emergency condi-
tions
››› .
End of emergency operation
Do not drive on if:
● smoke is coming from one of the tyres, ●
there is a smell of rubber,
● the vehicle vibrates,
● there is a rattling noise.
When is it no longer possible to continue
driving even using run-flat tyres?
● If one of the tyres has been severely dam-
aged in an accident, etc. If a tyre has been
badly damaged there is a risk that parts of
the tread can be thrown off and cause dam-
age to the fuel lines, brake pipes or fuel filler.
● It is also advisable to stop driving if severe
vibrations occur, or if the wheel starts over-
heating and gives off smoke. WARNING
When driving in emergency conditions, the
driving quality of the vehicle is considerably
impaired.
● The maximum permitted speed of 80 km/h
(50 mph) is subject to road and weather con-
ditions. Please observe related legal require-
ments.
● Avoid sharp turns and rapid manoeuvres,
and brake earlier than usual.
● Avoid driving over obstacles (e.g. kerbs) or
potholes.

Advice
For the sake of the environment
Old tyres must be disposed of according to
the laws in the country concerned. Note
● For technical reasons, it is not generally
possible to use the wheels from other vehi-
cles. This can also apply to wheels of the
same model. The use of wheels or tyres
which have not been approved by SEAT for
use with your model may invalidate the vehi-
cle's type approval for use on public roads.
● If the spare tyre is not the same as the
tyres that are mounted on the vehicle (e.g.
winter tyres) you should only use the spare
tyre for a short period of time and drive with
extra care. Refit the normal road wheel as
soon as possible. Wheel bolts
The design of wheel bolts is matched to the
rims. If different wheel rims are fitted, the
correct wheel bolts with the right length and
correctly shaped bolt heads must be used.
This ensures that wheels are fitted securely
and that the brake system functions correctly.
In certain circumstances, you should not use
wheel bolts from a different vehicle, even if it
is the same model
›››
page 147. After the wheels have been changed, the
tightening torque of the wheel bolts should
be checked as soon as possible with a torque
wrench
››› . The tightening torque for steel
and alloy wheels is 120 Nm. WARNING
If the wheel bolts are not tightened correctly,
the wheel could become loose while driving.
Risk of accident.
● The wheel bolts must be clean and turn
easily. Never apply grease or oil to them.
● Use only wheel bolts which belong to the
wheel.
● If the tightening torque of the wheel bolts
is too low, they could loosen whilst the vehi-
cle is in motion. Risk of accident! If the tight-
ening torque is too high, the wheel bolts and
threads can be damaged. CAUTION
The prescribed tightening torque for wheel
bolts for steel and alloy wheels is 120 Nm. Winter service
Winter tyres In winter conditions winter tyres will consid-
erably improve the vehicle's handling. Sum-mer tyres (width, rubber compound, tread
pattern) provide less grip on ice and snow.
Winter tyres must be inflated to a
pressure of
0.2 bar (2.9 psi/20 kPa) higher than the pres-
sures specified for summer tyres (see sticker
on fuel tank flap).
Winter tyres must be fitted on all four wheels.
Information on permitted winter tyre sizes
can be found in the vehicle's registration
documentation. Use only radial winter tyres.
All tyre sizes listed in the vehicle documenta-
tion also apply to winter tyres.
Winter tyres lose their effectiveness when the
tread is worn down to a depth of 4 mm.
The speed rating code ››› page 179, New
tyres and wheels determines the following
speed limits for winter tyres:
›
› › max. 160 km/h
max. 180 km/h
max. 190 km/h
max. 210 km/h
In some countries, vehicles which can exceed
the speed rating of the fitted tyre must have
an appropriate sticker in the driver's field of
view. These stickers are available from your
technical service. The legal requirements of
each country must be followed.
Do not have winter tyres fitted for unnecessa-
rily long periods. Vehicles with summer tyres Q

Advice
●
Never start the engine when the vehicle is
on the jack. Risk of accident.
● If work is to be carried out underneath the
vehicle, this must be secured by suitable
stands. Otherwise, there is a risk of injury. Note
The jack does not generally require any main-
tenance. If required, it should be greased us-
ing universal-type grease. Compact spare wheel* (temporary
spare wheel)
Fig. 154
Luggage compartment. Accessing
the spare wheel. The compact spare wheel (temporary spare
wheel for vehicles without the anti-puncture
kit) should only be used when strictly neces-
sary. The temporary spare wheel is stored under
the floor panel in the luggage compartment
and is attached by a thumbnut.
How to use the temporary spare wheel
Should you ever have a punctured tyre, the
compact temporary spare wheel is only inten-
ded for temporary use until you can reach a
workshop. The standard-size road wheel
should be replaced as soon as possible.
Please note the following restrictions when
using the temporary spare wheel. This tem-
porary spare wheel has been specially de-
signed for your vehicle, thus, it cannot be re-
placed by a temporary spare wheel from an-
other vehicle.
No other type of tyre (normal summer or win-
ter tyre) may be fitted on the compact tempo-
rary spare wheel rim.
Snow chains
For technical reasons, snow chains must
not
be used on the compact temporary spare
wheel.
If you have a puncture on one of the front
wheels when using snow chains, fit the com-
p act
temporary spare wheel in place of one of
the rear wheels. You can then attach the
snow chains to the wheel taken from the rear
and use this wheel to replace the punctured
front wheel. WARNING
● The tyre pressures must be checked and
corrected as soon as possible after fitting the
temporary spare wheel. The pressure of the
spare wheel sized 125/70R16 125/70R18
135/90R16 should be 4.2 bar
(61 psi/420 kPa). For other sizes, check the
label on the fuel cap. Failure to follow this in-
struction could result in an accident.
● Do not drive faster than 80 km/h (50 mph),
since higher speeds can cause an accident.
● Avoid heavy acceleration, hard braking and
fast cornering. Risk of accident.
● Never use more than one temporary spare
wheel at the same time, risk of accident.
● No other type of tyre (normal summer or
winter tyre) may be fitted on the compact
temporary spare wheel rim. Wheel change
Preparation work –
If you have a flat tyre or puncture, park the
vehicle as far away from the flow of traffic
as possible. Choose a location that is as
level as possible.
– All vehicle occupants should leave the ve-
hicle. They should wait in a safe area (for
instance behind the roadside crash barri-
er).
