Introduction
The fuel tank plug is on the rear right of the vehicle.
Additional information and warnings:
● Exterior detail ⇒ page 6
● Fuel ⇒ page 177
● Working in the engine compartment ⇒ page 180
WARNING
Refuelling or handling fuel carelessly can cause an explosion or fire re-
sulting in serious burns and injuries.
● Always make sure that you correctly close the fuel tank flap to avoid
evaporation and fuel spillage.
● Fuels are highly explosive and inflammable substances that can
cause serious burns and injuries.
● Fuel could leak out or be spilt if the engine is not switched off or if the
filler fuel nozzle is not fully inserted into the tank filler mouth when refu-
elling. This could lead to a fire, explosion and severe injuries.
● When refuelling, turn off the engine and turn off the ignition for safe-
ty reasons.
● Always turn off mobile telephones, radio system apparatus and other
radio wave emitting equipment before refuelling. Electromagnetic waves
could cause sparks and lead to a fire.
WARNING (Continued)
● Never enter the vehicle while refuelling. If it is absolutely necessary
to enter 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
combustion (e.g. cigarettes).
● Avoid static electricity and electro-magnetic radiation when refuel-
ling.
● Observe 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 vehicle. 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-
ister:
–Never place a fuel container, to fill it, inside the vehicle or on the
vehicle, for example, in the luggage compartment. Filling in these cir-
cumstances 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.

Several warning and control lamps light up for a few seconds when the igni-
tion is switched on while a test of the function is being carried out. They will
switch off after a few seconds.
In natural gas engines
The warning lamp lights up when both fuel types (petrol and natural gas)
have reached reserve level.
The warning lamp lights up when the vehicle is running in natural gas op-
erating mode. The warning lamp
switches off when the natural gas is exhausted. The
engine changes to operate with petrol.
Problem: If the vehicle is left parked for a long time immediately after refuel-
ling, the gas level indicator does not accurately indicate the same level
shown after refuelling when the vehicle is started up again. This is not due
to a leak in the system, but to a drop in pressure in the gas tank for techni-
cal reasons after a cooling phase immediately after refuelling.
WARNING
Driving with insufficient fuel reserve could result in the vehicle breaking
down in traffic and a serious accident.
● If the fuel level is too low then the fuel supply to the engine can be-
come irregular especially on slopes.
● If the engine “is choked” or stalls due to lack of or irregularity of the
fuel supply, 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 running out of fuel.
CAUTION
● Always pay attention to any lit lamps and to the corresponding descrip-
tions and instructions to avoid damage to the vehicle.
● Never run the fuel 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.
Note
The arrow next to the fuel pump symbol on the instrument panel ⇒ Fig. 105
indicates the side of the vehicle on which the fuel tank plug is located.

.
● Connect the pump filling nozzle to the gas filler mouth.
● The fuel tank will be full when the pump compressor automatically cuts
the supply.
● If you wish to finish refuelling in advance, press the button on the pump
to stop the flow.
Closing the fuel tank flap
● Check that the gas filler mouth retainer 2
is not trapped with the filler
nozzle. If necessary, place it in the filler mouth again.
● Insert the plug in the filler mouth.
● Close the tank flap. Make sure you hear it click into place.
WARNING
Natural gas is a highly explosive, easily flammable substance. Incorrect
handling of the natural gas can cause accidents serious burns and other
injuries.
● Before refuelling with natural gas, the filling mouth must be correctly
engaged. If you can smell gas, stop refuelling immediately.
WARNING
The vehicle is not prepared to use liquefied natural gas (LNG) and this
fuel must not be added under any circumstances. Liquefied natural gas
can cause the natural gas tank to explode resulting in serious injury.

Fuel
Introduction
You will find a factory-fitted sticker containing information on the type of
fuel for your vehicle on the inside of the fuel tank flap.
Additional information and warnings:
● ⇒ Booklet Maintenance Programme
● Refuelling ⇒ page 171
● Electronic power control and exhaust gases purification system

WARNING
Refuelling or handling fuel carelessly can cause an explosion or fire re-
sulting in serious burns and injuries.
● Fuel is a highly explosive, easily flammable substance.
● Observe current safety instructions and local regulations concerning
the handling of fuel.
Types of fuel
The type of fuel to use when refilling will depend on the vehicle's engine.
You will find a factory-fitted sticker containing information on the type of
fuel for your vehicle on the inside of the fuel tank flap.
SEAT recommends the use of sulphur-free or low sulphur fuel to reduce con-
sumption and prevent engine damage.

Petrol types
Vehicles with petrol engines must refuel using unleaded petrol according to
European norm EN 228 ⇒
.
Petrol 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 fuel
to reduce fuel consumption for petrol engines.
Petrol additives
The quality of the fuel influences running behaviour, performance and serv-
ice life of the engine. Therefore, it is recommended to refuel with good qual-
ity petrol containing the corresponding petrol additives. These additives will
help to prevent corrosion, keep the fuel system clean and prevent deposits
from building up in the engine.
If good quality petrol with additives are not available or engine problems
arise, the necessary additives must be added when refuelling ⇒

In the engine compartment
WARNING (Continued)
● Never open the bonnet if you see steam or coolant escaping from the
engine compartment. Hot vapours and coolant can cause serious burns.
Always wait until you cannot see or hear the sound of steam or coolant
coming from the engine compartment.
● Always allow the engine to cool down before opening the bonnet.
● Contact with hot elements of the engine and the exhaust system can
cause burns.
● Once the engine has cooled, follow the instructions below before
opening the bonnet:
–Engage the handbrake and place the gear selector lever in P or the
gear stick in neutral.
– Remove the key from the ignition.
– Keep children away from the engine compartment and never leave
them unsupervised.
● When the engine is warm or hot, the cooling system is pressurised.
Do not unscrew the cap on the coolant expansion tank when the engine
is hot. Otherwise, coolant may spray out under pressure causing burns
and serious injury.
–After cooling, carefully and slowly unscrew the cap anticlockwise,
gently pressing down on it.
– Always protect your face, hands and arms from hot coolant and
steam using a large, thick cloth.
● When refilling liquids, avoid spilling them on parts of the engine and
the exhaust system. Spilled liquids could cause a fire.WARNING
The high voltages of the electrical system can give electric shocks as well
as causing burns and serious injury and possibly even death!
● Never cause short circuits in the electrical system. The battery could
explode.
● To minimise the risk of electric shock and serious consequences
while the engine is running or starting the engine, note the following:
–Never touch the electrical wiring of the ignition system.
WARNING
In the engine compartment, there are rotating parts that could cause se-
rious injury.
● Never place your hands directly on or near the radiator fan. Touching
the rotor blades could seriously harm you. The ventilator works accord-
ing to the engine temperature and could start suddenly even when the ig-
nition is turned off and the key is removed.
● 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 as well as from the high-voltage ignition system. Always work with
the utmost caution.
–Always make sure that no parts of your body, jewellery, ties, loose
clothing and long hair can be trapped by the rotating parts of the en-
gine. Before any work, remove ties and jewellery ( necklaces, etc), tie
longhair back and tie all items of loose clothing to your body to make
sure that they cannot be trapped by engine components.
– Take extreme caution when operating the accelerator and remain
attentive. The vehicle could move, even if the handbrake is applied.
● Always make sure you have not left any objects, such as cloths or
tools, in the engine compartment. If any object is left in the engine com-
partment, this could cause malfunctions, engine faults and even a fire.
