2013 Seat Leon SC fuel pump

250Checking and refilling levels
For the sake of the environment
Do not overfill the fuel tank – it may cause the fuel to overflow if it becomes
warm.
Note
Diesel vehicles are fitted with a protective device that prevents the insertion
of the wrong fuel hose 1)
. It is only possible to refuel with Diesel nozzles.
● If the pump nozzle is worn, damaged, or if it is very small, it is possible
that it will not be able to open the protective device. Before trying to insert
the pump nozzle by turning it, try a different pump or request specialist
help.
● If you fill the tank from a reserve fuel canister, the protective device will
not open. One way to resolve this is to pour the fuel in very slowly. 
Refuelling natural gas
Fig. 152 Tank flap open:
gas filler mouth 1, filler
mouth retainer 2
Before refuelling, the engine and the ignition, mobile telephone and heat-
ing must be switched off separately
⇒ .
Read the instructions on how to use the natural gas pump carefully.
The vehicle is not prepared for refuelling with liquefied natural gas (LNG)
⇒ 
. Before refuelling with natural gas, make sure to add the appropriate
type of fuel ⇒ page 246.
Opening the fuel tank cap
The natural gas filler mouth is behind the fuel tank cap, next to the petrol
filler mouth.
● Unlock the vehicle with the key or with the central locking button 
situ-
ated on the driver door ⇒ page 87.
● Press on the rear area of the flap and open it.
Refuelling
Thing to note: if the ambient temperature is very high, the natural gas pump
protection against overheating may disconnect this automatically.
● Remove the plug from the gas filler mouth ⇒ Fig. 152 1
.
● 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 cap
● 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. 

Checking and refilling levels
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, engage the filler neck correctly. If
you 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 all natural gas pumps might not be operated in the
same way. If you do not know, ask a qualified employee at the petrol station
to do the refuelling.
● Noises heard when refuelling are normal and do not indicate the pres-
ence of damage to 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. Bonnet
Working on components in the engine compartment
Extra caution is necessary when working on components in
the engine compartment. Always be aware of the danger of injury and scalding as well as the risk of
accident or even fire when working in the engine compartment (e.g. when
checking and refilling fluids). Always observe the warnings listed below
and follow all general safety precautions. The engine compartment of the
vehicle is a potentially hazardous area ⇒ 
.
WARNING
● Switch the ignition off.
● Remove the ignition key.
● Apply the handbrake.
● If the vehicle has a manual gearbox, place the lever in neutral; if it
has an automatic gearbox, place the selector lever in position P.
● Wait for the engine to cool down.
● Keep children away from the engine compartment.
● Never spill liquids used for vehicle operation on the engine compart-
ment, as these may catch fire (e.g. the antifreeze in coolant).
● Take care not to cause short circuits in the electrical system, especial-
ly when working on the battery.
● If working inside the engine compartment, remember that, even when
the ignition is switched off, the radiator fan may start up automatically,
and therefore there is a risk of injury.
● Do not unscrew the cap on the coolant expansion tank when the en-
gine is hot. The cooling system is under pressure. 

Emergencies
Tow-starting
As a general rule, tow-starting is not recommended.
– Engage 2nd or 3rd gear before moving off.
– Press the clutch and hold the pedal down.
– Switch the ignition on.
– Once both vehicles are moving, release the clutch.
– As soon as the engine starts: press the clutch and put the gear
lever in neutral.
If the engine will not start, it is best to try starting it using the battery of an-
other vehicle ⇒ page 283 before attempting to tow start. You should only try
to tow-start the engine if jump starting is not successful. Tow-starting is an
attempt to start the engine via the movement of the wheels.
When tow-starting a vehicle with a petrol engine, do not tow it more than a
short distance, otherwise unburned fuel can enter the catalytic converter
and cause damage.
WARNING
The risk of accidents is high when tow-starting, as the towed vehicle can
easily be driven into the towing vehicle.
CAUTION
Do not tow vehicles for more than 50 m. Risk of damage to the catalytic con-
verter. Towing vehicles with a manual gearbox
Towing is relatively straightforward.
Please observe the relevant instructions ⇒ page 286.
The vehicle can be towed using a tow bar or tow rope in the normal way,
with all four wheels on the road; it can also be towed with either the front or
rear wheels lifted off the road. The maximum towing speed is 50 km/h (30
mph). 
Towing a vehicle equipped with automatic gearbox
Certain restrictions must be observed when towing your ve-
hicle. Please observe the relevant instructions ⇒ page 286.
The vehicle can be towed with a tow bar or tow rope in the normal way, with
all four wheels on the ground. When doing so, please note the following
points:
● Make sure the selector lever is in the N position.
● The vehicle must not be towed faster than 50 km/h (30 mph).
● The vehicle must not be towed further than 50 km (30 miles). Reason:
when the engine is not running, the gearbox oil pump does not work and
the gearbox is not adequately lubricated for higher speeds or longer distan-
ces.
If the vehicle has to be towed with a breakdown truck, it must only be sus-
pended at the front wheels. Reason: the drive shafts are located on the front
wheels. If the car is towed with the rear wheels lifted off the road (I.e. travel-
ling backwards), the drive shafts also turn backwards. The planetary gears
in the automatic gearbox then turn at such high speeds that the gearbox
will be severely damaged in a short time. 
