WARNING
If the warning lamps are ignored, the vehicle may stall in traffic, or may
cause accidents and severe injuries.
● Never ignore the warning lamps.
● Stop the vehicle safely as soon as possible.
● Park the vehicle away from the traffic, ensuring that there are no easi-
ly inflammable materials under the vehicle which could come into contact
with the exhaust system (e.g. dry grass, fuel).
● A faulty vehicle represents a risk of accident for the driver and for oth-
er road users. If necessary, switch on the hazard warning lamps and put
out the warning triangle to advise other drivers.
● Before opening the bonnet, switch off the engine and allow it to cool.
● In any vehicle, the engine compartment is a hazardous area and could
cause severe injuries ⇒ page 180.
CAUTION
Failure to heed the warning lamps when they appear may result in faults in
the vehicle. 

Refuelling with natural gas
Fig. 111 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
⇒ .
It is also essential to carefully read the instructions for the natural gas
pump.
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.
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 34.
● Press on the rear area of the flap and open it. Refuelling
Problem: If the ambient temperature is very high, the natural gas pump pro-
tection against overheating disconnects this automatically.
●
Remove the plug from the gas filler mouth ⇒ Fig. 111 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.
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. 

178At the filling station
Not all petrol additives have been shown to be effective. The use of unsuita-
ble petrol additives may cause significant damage to the engine and the
catalytic converter. Metal additives should never be used. Metal additives
may also be contained in petrol additives for improving anti-detonation rat-
ings or octane ratings ⇒ 
.
SEAT recommends “genuine Volkswagen Group fuel additives for petrol en-
gines”. These additives can be bought at SEAT Authorised Services, where
information on how to use them can also be obtained.
CAUTION
● Do not refuel 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!
● Only use fuel with an octane rating that is in line with the norm EN 228,
otherwise 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 seriously damage the en-
gine and the catalytic converter.
● If, in exceptional circumstances, petrol with a lower octane rating to that
recommended is used, only use moderate engine speeds and a light throt-
tle. Avoid using full throttle and overloading the engine. Otherwise engine
damage may occur. Fill up with fuel of a suitable octane rating as soon as
possible.
● Just filling one full tank of leaded fuel or with other metal additives
would seriously impair the efficiency of the catalytic converter and could
damage it. 
Natural gas
Natural gas, in addition to others, can be in liquid form. Liquefied natural gas (LNG) is the result of heavy cooling of natural gas.
Therefore its volume is considerably reduced compared with compressed
natural gas (CNG). In vehicles with a natural gas engine, liquefied natural
gas cannot be directly refilled, given that the gas would expand excessively
in the vehicle gas tank.
Therefore, vehicles with a natural gas engine must only be refuelled using
compressed natural gas
⇒ 
.
Natural gas quality and consumption
Natural gas is divided into the groups H and L depending on its quality.
Gas type H has a superior heating power and inferior nitrogen and carbon
dioxide content than type L. The higher the heating power of the natural
gas, the lower the consumption will be.
However, the heating power and the proportion of nitrogen and carbon di-
oxide can fluctuate within the quality groups. Therefore, vehicle consump-
tion can also vary when using one type of gas only.
The engine management automatically adapts to the natural gas used ac-
cording to its quality. Therefore, different quality gases can be mixed in the
tank, without the need for comprehensive draining before applying a differ-
ent quality gas.
Natural gas and safety
If you can smell gas or suspect that there is a leak ⇒ 
:
● Stop the vehicle immediately.
● Switch the ignition off.
● Open the doors to appropriately ventilate the vehicle.
● Immediately extinguish cigarettes.
● Move away from the vehicle or switch off objects that may cause sparks
or a fire.
● If you continue to smell gas, do not continue driving!
● Seek specialist assistance. Have the fault repaired. 
