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.
Closin
g the fuel tank cap
– Screw the tank cap to the right until it
“clicks”.
– T

urn the key in the lock, without releasing
the cap, cloc
kwise through 180°.
– Remove the key and close the flap until it
clicks

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, as

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 carry
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 sp ar

e 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 pi

lls should be removed from the
paintwork immediately.
● Never run the tank completely dry. Irregular
fuel sup
ply 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
complet
ely 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 l

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

Advice
Fuel Ty
pe s
of petrol The correct grade of petrol is listed inside the
fuel t
ank

flap.
The vehicle is equipped with a catalytic con-
verter and must only be run on unleaded pet-
rol. The petrol must comply with European
Standard EN 228 or German standard DIN
51626-1 and must be unleaded. You can re-
fuel with a maximum ethanol proportion of
10 % (E10). The types of petrol are differenti-
ated by their octane rating (RON).
The following titles appear on the corre-
sponding adhesive on the fuel tank flap:
Super unleaded 95 octane or normal 91 oc-
tane unleaded petrol
We recommend you use super 95 octane pet-
rol. If this is not available: normal 91 octane
petrol, with a slight decrease in power.
Super unleaded petrol with a minimum of 95
octanes
You should use super petrol with a minimum
of 95 octanes.
If super is not available, in an emergency you
may refuel with normal 91 octane petrol. In
this case only use moderate engine speeds
and a light throttle. Refuel with super as soon
as possible. Super unleaded 98 octane or super 95 oc-
tane un
l

eaded petrol
We recommend you use super plus 98 octane
petrol. If this is not available: super 95 oc-
tane petrol, with a slight decrease in power.
If super is not available, in an emergency you
may refuel with normal 91 octane petrol. In
this case only use moderate engine speeds
and a light throttle. Refuel with super as soon
as possible.
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 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 al
l petr

ol 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
Gr
oup F
uel Ad

ditives 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 ref uel

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!
● Never refuel with fuels containing a large
proportion of eth
anol (for example, E50, E85).
This could damage the fuel system.
● Just filling one full tank of leaded fuel or
fuel cont
aining other metal additives would
seriously impair the efficiency of the catalytic
converter.
● Only use fuel additives that have been ap-
proved b
y SEAT. Octane boosting or anti-
knock additives may contain metal additives
that could seriously damage the engine or
the catalytic converter. These additives must
not be used.
● High engine speed and full throttle can
damage the en
gine when using petrol with an
octane rating lower than the correct grade for
the engine. 200

Checking and refilling levels
Note
● You ma y
use petrol with a high octane num-
ber than the one recommended for your
engine.
● In those countries where unleaded petrol is
not avail
able, you may refuel with a fuel with
a low lead content. Diesel fuel
Please note the information on the inside of
the f
uel
tank

flap.
We recommend the use of diesel fuel which
complies to European standard EN 590. If
diesel fuel which meets European standard
EN 590 is not available, the Cetane number
(CZ) must, at minimum, be 51. If the engine
is equipped with a particulate filter, the sul-
phur content of the fuel must be below 50
parts per million.
Winter-grade diesel
Summer fuel becomes thicker in winter and it
is more difficult to start the engine. For this
reason, petrol stations in some countries al-
so offer winter diesel with improved fluidity
when cold (winter-grade diesel). Water in the fuel filter
1)
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
following warning:  Water in the
fuel filter. If this is the case, take the
vehicle to a specialised workshop so that
they can drain the fuel filter. CAUTION
● The vehic l

e is not designed for the use of
FAME fuel (biodiesel). The fuel system would
be damaged if you used biodiesel.
● Do not mix fuel additives, the so-called
“thinners”, petrol
or similar additives with
diesel fuel.
● If poor-quality diesel fuel is used, it may be
necess
ary to drain the fuel filter more fre-
quently than is specified in the Maintenance
Programme. We recommend having this done
by a specialised workshop. If water is allowed
to collect in the filter, this can cause engine
performance problems. Working in the engine compart-

onstant 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 190. 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. c

hecking 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 cool
ant 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 neutr
al or selector lever to position P.
● Keep children away from the vehicle.
● Never touch hot engine parts. There is a
risk of b
urns.
● Never spill liquids on a hot engine or on a
hot exhau
st gas system. This is a fire hazard.
● Avoid causing short-circuits in the electri-
cal sy
stem, particularly at the points where
the jump leads are attached ›››
 page 52.
The battery could explode. ●
Never touc h the r

adiator 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-
sulatin
g materials such as a blanket. Risk of
fire!
● Do not unscrew the cap on the coolant ex-
pansion t
ank 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 lar
ge, thick cloth to protect
against escaping coolant and steam.
● Always make sure you have not left any ob-
jects, suc
h 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 s
tarted 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 c

over 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 el
ectrical 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
sudden 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 pr
operly 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 c
orrectly closed then stop immediately
and close it correctly. 202

Checking and refilling levels
●
Only open and c lo
se the bonnet when there
is nobody within its range. CAUTION
When topping up service fluids, make sure
not to mi s

take them. Using the wrong fluids
could cause serious malfunctions and engine
damage! For the sake of the environment
Service fluids leaks are harmful to the envi-
ronment. F or thi

s 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

The layout of parts may vary depending on
the engine. Engine oil
General not

es The engine comes with a special, multi-grade
oil th
at

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.
204

Checking and refilling levels
The specifications (VW standards) set out in
the f o
llo
wing 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 per-
formed by a technical service or specialised
workshop.
The correct oil specifications for your engine
are listed in the ›››
 page 41.
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 has the LongLife
service program. If it lists the codes QI1, QI2,
QI3, QI4 or QI7, the interval service is de-
pendent on the time/distance travelled.
Flexible service intervals (LongLife service
intervals*)
Special oils and processes have been devel-
oped which, depending on the characteris-
tics and individual driving profiles, enable
the extension of the oil change service (Long-
Life service intervals). Because this oil is essential for extending the
service int
ervals, it must only be used ob-
serving the following indications:
● Avoid mixing it with oil for fixed service in-
terval
s.
● Only in exceptional circumstances, if the
engine oil l
evel is too low ››› page 206 and
LongLife oil is not available, it is permitted to
top up (once) with oil for fixed service inter-
vals ›››
 page 41 (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 also appear in
›››  page 41. 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 exceptional circumstances, if the engine
oil lev
el is too low ››› page 206 and you can-
not obtain the oil specified for your vehicle,
you can add a small quantity of oil conform-
ing to the specification ACEA A2 or ACEA A3
(petrol engines) or ACEA B3 or ACEA B4 (die-
sel engines) (up to 0.5 l). Vehicles with diesel particulate filter*
The Maintenanc

e 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 l
evel is too low ››› page 206 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). Note
Before a long trip, we recommend finding an
engine oil th

at 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. Warning lamp

Checking oil level
– Park the vehicle in a horizontal position.
– Briefly run the engine at idle speed until
the operating temper

ature is reached and
then stop.
– Wait for about two minutes.
– Pull out the dipstick. Wipe the dipstick with
a clean c

loth and insert it again, pushing it
in as far as it will go.
– Then pull it out again and check the oil lev-
el. Top up w

ith engine oil if necessary.
Depending on how you drive and the condi-
tions in which the vehicle is used, oil con-
sumption can be up to 0.5 l/1000 km. Oil consumption is likely to be higher for the first
5,000 km. For this r

eason the engine oil level
must be checked at regular intervals, prefera-
bly when filling the tank and before a jour-
ney. WARNING

age 42
Top up coolant when the level is below the
MIN (minimum) mark. Checking coolant level
– Park the vehicle in a horizontal position.
– Switch the ignition off.
– Read off the coolant level on coolant ex-
pansion t

ank. When the engine is cold, the
coolant level should be between the marks.
When the engine is hot, it may be slightly
above the upper mark.
Topping up coolant – Wait for the engine to cool down.
– Cover the coolant expansion tank cap with
a cloth and caref

ully unscrew it to the left
››› .
– Top up the coolant only if there is still cool-
ant in the e
xpan

sion tank, otherwise you
could damage the engine. If there is no
coolant in the expansion tank, do not con-
tinue driving. You should obtain professio- nal assistance ››› .
– If there is still some coolant in the expan-
sion t
ank, t op up t

o the upper mark.
– Top up with coolant until the level becomes
stabl

e.
– Screw the cap back on correctly.
Any los
s of coolant fluid normally indicates a
leak in the cooling system. Take the vehicle
straight to a specialised workshop to have
the cooling system examined. If there are no leaks in the engine cooling system, a loss of
coolant

can only occur if the coolant boils
and is forced out of the system as a result of
overheating. WARNING
● The coolin g sy

stem is under pressure. Do
not unscrew the cap on the coolant expan-
sion tank when the engine is hot: risk of
burns!
● The antifreeze and coolant fluid can be a
health haz
ard. Therefore, the antifreeze
should be stored in the original container in a
safe place out of reach of children. Failure to
comply could result in poisoning.
● If working inside the engine compartment,
remember that, even when the ignition i
s
switched off, the radiator fan may start up au-
tomatically, and therefore there is a risk of in-
jury. WARNING
If there is not enough anti-freeze in the cool-
ant sys t

em, the engine may fail leading to se-
rious damage.
● Please make sure that the percentage of
additive i
s correct with respect to the lowest
expected ambient temperature in the zone in
which the vehicle is to be used.
● When the outside temperature is very low,
the coolant
could freeze and the vehicle
would be immobilised. In this case, the heat-
ing would not work either and inadequately
dressed passengers could die of cold. 208
