Refuelling or handling fuel carelessly can cause an explosion or fire re-
su ltin
g in serious burns and injuries.
● Always make sure that you correctly close the fuel cap to avoid evap-
oration and fuel
spillage.
● Fuels are highly explosive and inflammable substances that can
cause seriou
s burns and injuries.
● Fuel could leak out or be spilt if the engine is not switched off or if the
fill
er fuel nozzle is not fully inserted into the tank filler neck when refuel-
ling. This could lead to a fire, explosion and severe injuries.
● When refuelling, turn off the engine, the auxiliary heating
(⇒ page 163) and t
urn off the ignition for safety reasons.
● Always turn off mobile telephones, radio apparatus and other radio
wave emittin
g equipment before refuelling. Electromagnetic waves could
cause sparks and lead to a fire. WARNING (Continued)
● Nev er enter the vehicle while refuelling. If it is absolutely necessary
t o ent
er the vehicle, close the door and touch a metal surface before
touching the filler nozzle again. This will prevent the generation of static
electricity. Sparks could cause a fire when refuelling.
● Never handle fuel close to open flames, sparks or objects with slow
combu
stion (e.g. cigarettes).
● Avoid static electricity and electro-magnetic radiation when refuel-
ling.
● Ob
serve the safety regulations of the service station.
● Never spill fuel on the vehicle or in the luggage compartment. WARNING
For safety reasons, SEAT does not recommend carrying a spare fuel canis-
ter in the v
ehicle. Fuel could be spilled and catch fire, above all in case of
an accident and this applies to a full container as well as empty contain-
ers. This could lead to explosions, fires and injuries.
● Observe the following if you exceptionally have to carry fuel in a can-
ist
er:
– Never place a fuel container to fill it inside the vehicle or on the ve-
hicle, f
or example, in the luggage compartment or on the tailgate.
Filling in these circumstances could create an electrostatic charge
and spark that could ignite fuel fumes.
– Always place the canister on the ground to fill it.
– Insert the fuel nozzle into the mouth of the canister as far as possi-
ble.
265
Checking and refilling levels WARNING (Continued)
– If you are using a metal fuel canister, the nozzle must always touch
the c ani
s
ter while it is being filled to avoid static electricity.
– Follow the legal requirements for the use, storage and transport of
spar
e fuel canisters.
– Insure that the fuel container complies with manufacturing stand-
ards, f
or example, ANSI or ASTM F852-86. CAUTION
● Always remove any fuel spilled on the vehicle paintwork immediately to
av oid d
amage to the wheel housing, the tyre and vehicle paintwork.
● Refuelling a petrol engine with diesel or a diesel engine with petrol can
cause seriou
s engine and fuel system damage; the resulting malfunctions
are not covered by the SEAT warranty. If you refuel with the wrong type of
fuel, never start the engine. This applies to even the smallest amount of the
wrong fuel. You should obtain professional assistance. With the engine run-
ning, the composition of the wrong fuel could significantly damage the fuel
system and the engine itself.
● In vehicles with a diesel engine, under no cir
cumstances should you re-
fuel or drive with petrol, kerosene, heating oil or any other type of different
fuel. Other types of fuels could cause serious damage to the engine and to
the fuel supply system and the resulting problems are not covered by the
SEAT warranty. For the sake of the environment
Fuels can contaminate the environment. Collect any spilt service fluids and

Checking and refilling levels WARNING
Driving with insufficient fuel reserve could result in the vehicle breaking
down in tr affic
and a serious accident.
● If the fuel level is too low then the fuel supply to the engine can be-
come irre
gular especially on slopes.
● If the engine “is choked” or stalls due to lack of or irregularity of the
fuel s
upply, the power steering as well as all of the driver assistance sys-
tems including braking assistance will stop working.
● Always refuel when there is only one quarter of the fuel tank left to
avoid runnin
g out of fuel. CAUTION
● Always pay attention to any lit lamps and to the corresponding descrip-
tion s
and instructions to avoid damage to the vehicle.
● Never run the tank completely dry. An irregular fuel supply may lead to
ignition faults
and unburnt fuel could enter the exhaust system. This could
damage the catalytic converter filter or the diesel particulate filter! Note

Vehic
l
es with petrol engines must refuel using unleaded petrol according to
European norm EN 228 ⇒ .
Petr o
l types are categorised according to their octane number (e.g. 91, 95,
98 or 99 RON (RON = “Research Octane Number”). You may use petrol with
a high octane number than the one recommended for your engine. Howev-
er, this has no advantage in terms of fuel consumption and engine power.
SEAT recommends refuelling with a low sulphur content or sulphur-free pet-
rol to reduce petrol consumption for petrol engines.
Petrol additives
The quality of the fuel influences running behaviour, performance and serv-
ice life of the engine. For this reason, you should use good quality petrol
containing a mixture of additives. These additives will help to prevent corro-
sion, keep the fuel system clean and prevent deposits from building up in
the engine.
If good quality petrol with additives 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 unsuita-
ble petrol additives could damage the engine. These additives are available
from qualified workshops, who will inform you of their application. CAUTION
● Only use fuel with an octane rating that is in line with the norm EN 228,
other w
ise significant damage could be caused to the engine and fuel sys-
tem. Furthermore, it could lead to a loss of performance with the conse-
quent engine fault.
● The use of unsuitable petrol additives could damage the engine.
269
Checking and refilling levels
● If, in exceptional circumstances, petrol with a lower octane rating to that
r ec
ommended is used, only use moderate engine speeds and a light throt-
tle. Avoid using full throttle and overloading the engine. Otherwise you may
damage the engine. Fill up with fuel of a suitable octane rating as soon as
possible.
● Do not refuel if the filler indicates that the fuel contains metal. LRP (lead
repl
acement petrol) fuels also contain high concentrations of metal addi-
tives. This could damage the engine!
● Just one full tank of leaded fuel would seriously impair the efficiency of
the catalytic
converter and could damage it.
Diesel Diesel fuel
Diesel
f
uel must correspond to European standard EN 590 (In Germany,
EN 590 or DIN 51628).
The use of diesel fuel with a high sulphur percentage requires shorter serv-
ice intervals ⇒ Booklet Maintenance Programme ⇒ . Your qualified work-
shop wi l
l be able to tell you which countries have diesel with a high sulphur
content.
Do not mix fuel additives (thinners, or similar additives) with diesel fuel.
Winter-grade diesel
When using “summer-grade diesel fuel”, difficulties may be experienced at
temperatures below 0°C (+32°F) because the fuel thickens due to wax sepa-
ration. For this reason, “winter-grade diesel fuel” is available in Germany,
for example, during the cold months. It can be used at temperatures as low
as -20°C (-4°F).
In countries with different climatic conditions, other types of diesel fuel are
available that are suitable to local temperatures. SEAT qualified workshops
and filling stations in the country concerned will inform you on the type of
diesel fuels available. A cold diesel engine makes more noise during winter temperatures than
summer temper
atures. Furthermore, the exhaust fumes may turn slightly
bluish while the engine is heating. The quantity of exhaust gases will de-
pend on the outside temperature.
Filter pre-heater
Vehicles with a diesel engine are fitted with a fuel filter pre-heater. This en-
sures that the fuel system remains operational to approx. -24°C (-11.2°F),
provided you use winter-grade diesel which is safe to -15°C (+5°F).
However, if the fuel has waxed to such an extent that the engine will not
start at temperatures of under -24°C (-11.2°F), simply place the vehicle in a
warm garage or workshop for a while to heat up.
Auxiliary heater
Vehicles with a diesel engine may be fitted with an auxiliary heater. The
heater runs off the fuel from the fuel tank. On doing so, smells and steam
may be noticed outside the vehicle for a short period. This is normal and it
is not an indication of a fault in the vehicle.
Whenever there is little fuel in the tank (reserve), the auxiliary heater auto-
matically switches off. WARNING
Never use start boosters. An aerosol start booster could explode or cause
a sud den ri
se in engine speed leading to engine damage and serious in-
jury. Safety First Operating instructions Practical tips Technical Data

The emergency start or jump start will not be possi-
ble either!
● Top up with AdBlue at the latest 1000 km or 600 miles before it runs
out.
● Do not a
llow the AdBlue to run too low. WARNING
AdBlue is an irritant, corrosive liquid that can cause injuries if it touches
the skin, ey e
s or respiratory organs.
● If AdBlue get in contact with eyes and skin, rinse for at least 15 mi-
nutes
with plenty of water and seek medical help.
● If the AdBlue is swallowed, wash the mouth with plenty of water for at
lea
st 15 minutes. Do not try to provoke vomiting unless recommended by
a Doctor. Seek medical advice immediately. CAUTION
AdBlue damages surfaces such as painted vehicle parts, plastic, items of
clothin g and c
arpets. Spilt AdBlue should be removed as quickly as possi-
ble using a damp cloth and plenty of cold water.
● If the AdBlue has crystallised, remove with warm water and a sponge.

Information on AdBlue In vehicles with Selective Catalytic Reduction, a special urea solution (AdBl-
ue) is
inj
ected into the exhaust gas system in front of the catalytic converter
to reduce nitrogen oxide emissions.
The consumption of AdBlue depends on individual driving style, the tem-
perature at which the system operates and the outside temperature where
the vehicle is driven. AdBlue is kept in an independent tank in the vehicle and should be refilled
at an offici
al supplier. The AdBlue tank holds about 17 litres.
A message will be displayed on the instrument panel around 2400 km be-
fore the next service to indicate that AdBlue must be refilled ⇒ page 273. If
you ignore this message and do not refill, you will be unable to start the en-
gine afterwards ⇒ page 271.
SEAT recommends contacting a specialist workshop. If you are unable to
visit a qualified specialist workshop, you should temporarily refill with a
minimum of 10.0 litres of AdBlue. Only refill using AdBlue expressly ap-
proved by SEAT.
When the indicators and light simultaneously, there is a fault. SEAT
recommends visiting the closest qualified workshop.
