● Tow-starting and towing away ⇒ page 276
WARNING
Switching off the engine while driving makes stopping the vehicle diffi-
cult. As a consequence you may lose control of the vehicle and there is a
risk of serious accident.
● The assisted braking and steering systems, the airbag system, safety
belts and certain safety equipment are only active while the engine is
running.
● The engine should only be switched off when the vehicle is at a
standstill.
WARNING
While the engine is running or starting it could help reduce the risk of se-
rious injury.
● Never start or leave the engine running in poorly ventilated or closed
spaces. Exhaust gas contains carbon monoxide, a toxic, colourless and
odourless gas. Carbon monoxide can cause people to lose conscious-
ness. It can also cause death.
● Never leave the vehicle unattended if the engine is running. The vehi-
cle could move off suddenly or something unexpected could happen re-
sulting in damage and serious injury.
● Never use start boosters. Cold start sprays could explode or increase
the engine speed unexpectedly. 

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. 

172At the filling station
WARNING (Continued)
– If you are using a metal fuel canister, the nozzle must always touch
the canister while it is being filled to avoid static electricity.
– Follow the legal requirements for the use, storage and transport of
spare fuel canisters.
– Insure that the fuel container complies with manufacturing stand-
ards, for example, ANSI or ASTM F852-86.
CAUTION
● Always remove any fuel spilled anywhere on the vehicle to avoid dam-
age to the wheel housing, the tyre and vehicle paintwork.
● Refuelling a petrol engine with diesel can cause serious 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 ob-
tain professional assistance. With the engine running, the composition of
the wrong fuel could significantly damage the fuel system and the engine
itself.
For the sake of the environment
Fuels can contaminate the environment. Collect any spilt service fluids and
allow a professional to dispose of them. Control lamps and fuel gauge

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. 

tank flap ⇒ page 177. ●
If the automatic filler nozzle is operated correctly, it will switch itself off
as soon as the fuel tank is full ⇒ 
.
● Do not continue to refuel if it is turned off! Otherwise, this will fill the ex-
pansion chamber and fuel may leak out if the ambient conditions are warm.
Closing the fuel tank flap
● Screw on the fuel tank filler plug in a clockwise direction until it is fully
inserted with a click.
● Insert the vehicle key into the lock cylinder of the fuel tank plug, turn the
key in a clockwise direction and remove the key.
● Press the tank flap until it clicks into place. The fuel tank flap must be
flush with the body contour.
WARNING
Do not continue refuelling once the fuel nozzle has switched itself off.
The fuel tank may be filled too much. As a result, fuel may spurt out and
spill. This could lead to a fire, explosion and severe injuries.
CAUTION
● Always remove any fuel spilled anywhere on the vehicle to avoid dam-
age to the wheel housing, the tyre and vehicle paintwork.

● 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. 

Note
● The filling nozzles of natural gas pumps can differ in the way they are
operated. If you are unacquainted with the pump, it is advisable that a
member of staff of the service station performs the refuelling operation.
● Noises heard when refuelling are normal and do not indicate the pres-
ence of a fault in the system.
● The vehicle natural gas system is prepared both for refuelling with a
small compressor (slow refuel) and a large compressor (fast refuel) in natu-
ral gas service stations. 
