thi s
w
ork, ensure that all surfaces, seams,
joints and components in the engine com-
partment are given anti-corrosion treatment. WARNING
● When work in

g in the engine compartment,
always observe the safety warnings
››› page 273.
● Before opening the bonnet, switch the en-
gine off, app
ly the handbrake firmly and al-
ways remove the key from the ignition.
● Allow the engine to cool before you clean
the engine comp
artment.
● Do not clean, for example, the vehicle un-
derbody, wheel ar
ches or wheel trims without
protecting your hands and arms. You may cut
yourself on sharp-edged metal parts. Failure
to comply could result in injury.
● Moisture, ice and salt on the brake system
may
affect braking effectiveness. Risk of acci-
dent. Directly after washing, avoid sudden
and sharp braking.
● Never touch the radiator fan. It is tempera-
ture-c
ontrolled and could start automatically,
even when the key is removed from the igni-
tion! For the sake of the environment
Fuel, grease and oil deposits can be removed
when the engine i s

washed. The polluted wa-
ter must be cleaned in an oil separator. For
this reason, engine washing should be car- ried out only by a specialised workshop or a
petro
l

station. Caring for the vehicle interior
Scr een f

or the radio/Easy Connect*
and control panel* The display can be cleaned with a soft cloth
and a prof
e

ssionally available “LCD cleaner”.
Moisten the cloth with a small amount of the
cleaning fluid.
The Easy Connect control panel* should first
be cleaned with a brush so that no dirt goes
into the device or between the keys and
housing. Next, we recommend cleaning the
Easy Connect control panel* using a cloth
dampened with water and washing-up liquid. CAUTION
● To av oid s

cratching the screen, do not wipe
the display with a dry cloth.
● To avoid damage, ensure that no liquid
goes
into the Easy Connect control panel*. Cleaning plastic parts and the dash

anel –
Use a clean, damp cloth to clean plastic
par ts

and the dash panel. –
If this
does not provide satisfactory results,
use a special solvent-free plastic cleaning
product. WARNING
Never clean the dash panel and the airbag
modul e s

urface with cleaners containing sol-
vents. Solvents cause the surface to become
porous. If the airbag triggered, plastic parts
could become detached and cause injuries. CAUTION
Cleaning products which contain solvents will

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 e x

ceptional 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 spare 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
sy

stem 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-
m atic fi

ller nozzle has switched off, this may
cause the fuel to overflow if it becomes warm. Note
There is no emergency mechanism for the
manua l

release of the fuel tank flap. If neces-
sary, request assistance from specialised per-
sonnel. Fuel
Ty
pe

s of petrol The correct grade of petrol is listed inside the
f
uel
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). »

Advice
The following titles appear on the corre-
s pondin
g a
dhesive 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 unleaded 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 f
uel 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

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 ››› .
S EA
T r

ecommends “genuine Volkswagen
Group Fuel 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 r ef

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!
● Nev er r

efuel with fuels containing a large
proportion of
ethanol (for example, E50, E85).
This could damage the fuel system.
● Just filling one full tank of leaded fuel or
fuel c
ontaining other metal additives would
seriously impair the efficiency of the catalytic
converter.
● Only use fuel additives that have been ap-
prov
ed by 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
damag
e the engine when using petrol with an
octane rating lower than the correct grade for
the engine. Note
● You m a

y use petrol with a high octane num-
ber than the one recommended for your en-
gine.
● In those countries where unleaded petrol is
not avai
lable, you may refuel with a fuel with
a low lead content. Diesel fuel
Please note the information on the inside of
the f
uel
t

ank flap.

Checking and refilling levels
We recommend the use of diesel
f uel 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). CAUTION
● The v ehic

le 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”, petro
l or similar additives with
diesel fuel.
● If poor-quality diesel fuel is used, it may be
neces
sary 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. AdBlue
®
Inf orm
ation on AdBlue ® The consumption of AdBlue
®
depends on
y
our personal driving style, the temperature
of the system and on the outdoor tempera-
ture when the vehicle is used.
AdBlue ®
freezes at temperatures of -11°C
(+13°F). The system has heating elements
that guarantee its operation even at low tem-
peratures.
The AdBlue ®
tank level capacity is approxi-
mately 10.4 litres.
The AdBlue ®
tank should never be empty.
When the distance to empty drops below
2400 km, a warning to refill the AdBlue ®
tank
will appear on the dash panel display
››› page 271. If this information is ignored,
later on it will not be possible to re-start the
engine. If this warning does not appear, it is
not necessary to refill the AdBlue ®
tank.
AdBlue ®
is a registered brand of the German
Association of the Automotive Industry (VDA)
and is also known as AUS32 or DEF (Diesel
Exhaust Fluid). CAUTION
Filling the AdBlue ®
tank e
xcessively can
cause damage to the tank. Refilling AdBlue

vehicle on a flat surface. If the vehi-
cle is not parked on a flat surface, but, for ex-
ample, on a slope or on the side of a curb,
the level indicator may not detect the load
properly.
If a warning message about AdBlue ®
levels
appears on the dash panel display, fill at
least the minimum amount required (approx.
5 litres). Only after adding this amount will
the system detect that AdBlue ®
has been
added and you will be able to start the en-
gine again. The maximum amount that can
be refilled is 11 litres.
Switch the ignition off. If the ignition is not
switched off during refilling, the warning to

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 259. The engine compart-
ment of the vehicle is a hazardous area ››› .
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
