The tank flap is released manually and is lo-
cated at the rear of the vehicle on the right.
The tank holds approximately 45 litres.
Opening the fuel tank cap
– Lift the lid.
– Hold the cap firmly with one hand, then in-
sert the k

ey into the lock and rotate 180° to
the left.
– Unscrew the cap, turning it anticlockwise.
Clos
ing the fuel tank cap
– Screw the tank cap to the right until it
“click

s”.
– Turn the key in the lock, without releasing
the cap, c

lockwise through 180°.
– Remove the key and close the flap until it
click

s into place. The tank cap is secured
with an anti-loss attachment
If the automatic filler nozzle is operated cor-
rectly, it will switch itself off as soon as the tank is “full”. Never attempt to fill beyond
this point, a

s this will fill the expansion
chamber. Fuel may leak out if ambient condi-
tions are warm.
The correct fuel grade for your vehicle is giv-
en on a sticker on the inside of the fuel tank
flap. WARNING
● Fuel i

s highly flammable and can cause se-
rious burns and other injuries.
–Never smoke or come into contact with
sparks when filling the fuel tank of the
vehicle or a spare fuel canister with fuel.
This is an explosion hazard.
– Follow legal requirements for the use of
spare fuel canisters.
– For safety reasons we do not recommend
carrying a spare fuel canister in the vehi-
cle. The canister could be damaged in an
accident and leak.
● If, in exceptional circumstances, you have
to carr
y a spare fuel canister, please observe
the following:
–Never fill the spare fuel canister inside
the vehicle or on it. An electrostatic
charge could build up during filling, caus-
ing 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 possible. –
If the s p

are fuel canister is made of met-
al, 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 s

pills should be removed from the
paintwork immediately.
● Never run the tank completely dry. Irregular
fuel s
upply can cause misfiring. As a result,
unburnt fuel could enter the catalytic convert-
er and cause damage.
● When filling the fuel tank after having run it
compl
etely 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 fi

ller nozzle has switched off, this may
cause the fuel to overflow if it becomes warm. 199

Petrol P etr
o
l types The correct petrol types are listed on a sticker
ins
ide the f

uel tank flap.
Only unleaded petrol conforming to standard
DIN EN 228 may be used for vehicles with
catalytic converters (EN = “European Stand-
ard”).
Types of petrol differ from each other accord-
ing to the octane rating, for example: 91, 95,
98 RON (RON = “Research Octane Number”,
unit for determining the knock resistance of
petrol). You may use petrol with a higher oc-
tane number than the one recommended for
your engine. However, this has no advantage
in terms of fuel consumption and engine
power. CAUTION
● Ev en one t

ankful of leaded fuel would per-
manently impair the efficiency of the catalyt-
ic converter.
● High engine speed and full throttle can
damag
e 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-
ous ly

impair the efficiency of the catalytic
converter. Additives for petrol
The quality of the fuel influences the behav-
iour, po
w

er 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 the
fuel 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 f
uel

additives for petrol engines”.
These additives can be bought at SEAT deal-
ers, where information on how to use them
can also be obtained. CAUTION
Do not refuel if the filler indicates that the
fuel c

ontains metal. LRP (lead replacement
petrol) fuels contain high concentrations of
metal additives. Using them may damage the
engine! Diesel
Die sel Diesel fuel
mus
t
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.

If your vehicle has a diesel engine and is
equipped with a fuel filter with a water sepa-
rator, the instrument panel may display the

 Water in the fuel filter.
If thi s
is the case, take the vehicle to a speci-
alised workshop so that they can drain the
fuel filter.
Biodiesel* CAUTION
● Your v

ehicle 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 ex
clusively 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 us
in

g “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 place the
vehicle in a warm place for a while. CAUTION
Do not mix fuel additives, the so-called “thin-
ners”, or s imi

lar additives with diesel fuel. Working in the engine compart-

WARNING
All work on the engine or in the engine com-
par tment, 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 coo
lant 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.
● App

ly the handbrake and move the gear
lever t
o 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 exh
aust 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 52.
The battery could explode.
● Never touch the radiator fan. It is tempera-
ture c
ontrolled and could start automatically,
even when the engine has been switched off
and the key removed from the ignition! ●
Never c o

ver the engine with additional in-
sulating materials such as a blanket. Risk of
fire!
● Do not unscrew the cap on the coolant ex-
pans
ion 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 l
arge, thick cloth to protect
against escaping coolant and steam.
● Always make sure you have not left any ob-
jects, s
uch as cleaning cloths or tools, in the
engine compartment.
● If you have to work underneath the vehicle,
you mus
t 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 ac c

elerate 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
syst
em 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. WARNING
If the bonnet is not correctly closed, it could
sud den

ly open while driving leaving the driv-
er without visibility. This could result in a se-
rious accident.
● After closing the bonnet, always check that
it is
properly secured by the locking mecha-
nism in the lock carrier piece. The bonnet
must be flush with the surrounding body pan-
els.
● While driving, if you notice that the bonnet
is not
correctly closed then stop immediately
and close it correctly.
● Only open and close the bonnet when there
is no
body within its range.202

Wheels
Wheel s
and ty
res
General notes Avoiding damage
– If you have to drive over a kerb or similar
ob s

tacle, drive very slowly and at a right
angle.
– Keep grease, oil and fuel off the tyres.
– Inspect the tyres regularly for damage
(cuts, c r

acks or blisters, etc.). Remove any
foreign objects embedded in the treads.
Storing tyres
– When you remove the tyres, mark them in
order to m

aintain the same direction of ro-
tation when they are installed again.
– When removed, the wheels and/or tyres
should be s

tored 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 165.
The tread depth of new tyres may vary, ac-
cording to the type and make of tyre and the
tread pattern. Concealed damage
Damage t

o 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 tyr e

s do not have maximum grip dur-
ing the first 500 km. Drive particularly care-
fully to avoid possible accidents.
● Never drive with damaged tyres. This may
cause an ac
cident.
● If you notice unusual vibrations or if the ve-
hicle p
ulls to one side when driving, stop the
vehicle immediately and check the tyres for
damage. Tyre pressure monitoring system
Fig. 188
Location of the tyre pressure sticker. The correct tyre pressure can be seen on the
s
tic
k

er on the inside of the fuel tank flap
››› Fig. 188.
1. Read the required tyre inflation pressure from the stic
ker. The values refer to Sum-
mer tyres.
2. The tyre pressures should only be checked when the tyre
s are cold. The slightly raised
pressures of warm tyres must not be re-
duced.
3. Adjust the tyre pressure to the load you are carr
ying.
212

Wheels
Tyre pressure
The c orr
ect
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.
Depending on the vehicle, tyre pressure can
be adjusted to medium load to improve driv-
ing comfort (“comfort” tyre pressure). When
driving with comfort tyre pressure fuel con-
sumption may increase slightly. WARNING
A tyre can easily burst if the pressure is too
low , c

ausing an accident!
● At continuously high speeds, a tyre with in-
sufficient
pressure flexes more. In this way it
becomes too hot, and this can cause tread
separation and tyre blow-out. Always observe
the recommended tyre pressures.
● If the tyre pressure is too low or too high,
the tyre
s will wear prematurely and the vehi-
cle will not handle well. Risk of accident! For the sake of the environment
Under-inflated tyres will increase fuel con-
sumption. Tyre useful life
Fig. 189
Tyre tread wear indicators. Fig. 190
Diagram for changing wheels The useful life of tyres is dependent on tyre
pr
e
s

sure, driving style and fitting.
Wear indicators
The original tyres on your vehicle have
1.6 mm high “tread wear indicators”
››› Fig. 189, running across the tread. De- pending on the make, there will be 6 to 8 of
them evenly

spaced around the tyre. Mark-
ings on the tyre sidewall (for instance the let-
ters “TWI” or other symbols) indicate the po-
sitions of the tread wear indicators. The mini-
mum tread depth required by law is 1.6 mm
(measured in the tread grooves next to the
tread wear indicators). Worn tyres must be re-
placed. Different figures may apply in export
countries ››› .
T y
r

e pressure
Incorrect tyre pressure causes premature
wear and could cause tyre blow-out. For this
reason, the tyre pressure should be checked
at least once per month ››› page 212.
Driving style
Fast cornering, heavy acceleration and hard
braking all increase tyre wear.
Changing wheels around
If the front tyres are worn considerably more
than the rear ones it is advisable to change
them around as shown ››› Fig. 190. The use-
ful life of all the tyres will then be about the
same time.
Wheel balance
The wheels on new vehicles are balanced.
However, various factors encountered in nor-
mal driving can cause them to become unbal-
anced, which results in steering vibration. »

Advice
Unbalanced wheels should be rebalanced, as
they other
w
ise cause excessive wear on
steering, suspension and tyres. A wheel must
also be rebalanced when a new tyre is fitted.
Incorrect wheel alignment
Incorrect wheel alignment causes excessive
tyre wear, impairing the safety of the vehicle.
If tyres show excessive wear, you should
have the wheel alignment checked by a Tech-
nical Service. WARNING
There is a serious danger of accidents if a tyre
bur s

ts during driving!
● The tyres must be replaced at the latest
when the trea
d wear indicators are worn
››› page 213. Failure to follow this instruction
could result in an accident. Worn tyres do not
grip well at high speeds on wet roads. There
is also a greater risk of “aquaplaning”.
● At continuously high speeds, a tyre with in-
sufficient
pressure flexes more. This causes it
to overheat. This can cause tread separation
and tyre blow-out. Risk of accident. Always
observe the recommended tyre pressures.
● If tyres show excessive wear, you should
have the ru
nning gear checked by a Technical
Service.
● Keep chemicals such as oil, fuel and brake
fluid awa
y from tyres.
● Damaged wheels and tyres must be re-
plac
ed immediately! For the sake of the environment
Under-inflated tyres will increase fuel con-
sumption. New tyres and wheels
New tyres and wheels have to be run in.
The tyr
e

s and wheel rims are an essential
part of the vehicle's design. Those approved
by SEAT are specially matched to the charac-
teristics of the vehicle and make a major con-
tribution to good road-holding and safe han-
dling ››› .
T y
r

es should be replaced at least in pairs and
not individually (i.e. both front tyres or both
rear tyres together). A knowledge of tyre des-
ignations makes it easier to choose the cor-
rect tyres. Radial tyres have the tyre designa-
tions marked on the sidewall, for example:
195/65 R15 91T
This contains the following information:
Tyre width in mm
Height/width ratio in %
Tyre construction: Radial
Rim diameter in inches

T The tyres could also have the following infor-
mation:
● A direction of

rotation symbol
● “Reinforced” denotes heavy-duty tyres.
The manufact
uring date is also indicated on
the tyre sidewall (possibly only on the inner
side of the wheel).
“DOT ... 1103 ...” means, for example, that
the tyre was produced in the 11th week of
2003.
We recommend that work on tyres and
wheels be carried out by a Technical Service.
They are familiar with the procedure and
have the necessary special tools and spare
parts as well as the proper facilities for dis-
posing of the old tyres.
Any technical service has full information on
the technical requirements when installing or
changing tyres, wheels or wheel trims.
Note for Italy: A SEAT Service Centre should
be consulted whether different sized wheels
or tyres to those originally fitted by SEAT may
be fitted, as well as the combinations al-
lowed between the front axle (axle 1) and
back axle (axle 2). WARNING
● We r ec

ommend that you use only wheels
and tyres which have been approved by SEAT 214

Wheels
for your model. Failure to do so could impair
vehic
l
e handling. Risk of accident.
● Avoid running the vehicle on tyres that are
more than 6
years old. If you have no alterna-
tive, you should drive slowly and with extra
care at all times.
● Never use old tyres or those with an un-
known “his
tory of use”.
● If wheel trims are retrofitted, you must en-
sure th
at the flow of air to the brakes is not
restricted. This could cause the brake system
to overheat.
● All four wheels must be fitted with radial
tyre
s of the same type, size (rolling circumfer-
ence) and the same tread pattern. For the sake of the environment
Old tyres must be disposed of according to
the la w

s in the country concerned. Note
● For t ec

hnical 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
tyre
s 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
po

ssible. Wheel bolts
The design of wheel bolts is matched to the
rims. If diff
er

ent 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 190. WARNING
If the wheel bolts are not tightened correctly,
the wheel c ou

ld become loose while driving.
Risk of accident.
● The wheel bolts must be clean and turn
eas
ily. Never apply grease or oil to them.
● Use only wheel bolts which belong to the
wheel.
● If the pr

escribed torque of the wheel bolts
is t
oo 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
bolt s

for steel and alloy wheels is 120 Nm. Winter service
Wint er ty

res In winter conditions winter tyres will consid-
erab
ly

improve the vehicle's handling. The
design of summer tyres (width, rubber com-
pound, tread pattern) gives 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 214, New
tyres and wheels determines the following
speed limits for winter tyres: ››› max. 160 km/h (99 mph)
