Practical tips
Ethanol fuel
3 V
alid for: vehicles with Totalflex engines
You can recognise vehicles with Totalflex en-
gines
1)
by label on the fuel tank lid with the
marking “Petrol/ethanol”.
Vehicles with Totalflex engine can run with
unleaded petrol (95 octane / 91 AKI) accord-
ing to ANP No. 57 and with fuels with any high
percentage of ethanol. The vehicle is refuel-
led in the same way as petrol refuelling.
Also consider that

Note
SEAT recommends filling the tank exclu-
siv
ely with petrol every 10,000 km to de-
crease impurities that using E100 ethanol
fuel might have left in the engine.
Diesel
3 V
alid for: vehicles with diesel engines
Please note the information on the inside of
the fuel tank flap.
We recommend you use Diesel according to
standard EN 590.
The diesel can thicken at very low tempera-
t
ures, thus affecting the start or operation of
the engine. Ask your service station attendant
if their diesel is suitable for winter use.
Water in the fuel filter
2)
If your vehicle has a diesel engine and is
equipped with a fuel filter with a water sep-
arator, the instrument panel may display the
following warning:
Water in the fuel
filter. If this is the case, take the vehicle to
a specialised workshop so that they can
drain the fuel filter.
CAUTION
●
Ne
ver use of FAME (biodiesel), petrol,
heating oil, other fuels or thinning agents
as they can cause severely damage the
fuel system and the engine.
●
If the wrong fuel has been filled, do not
start the engine under any circumstances.
Risk of damaging the fuel system and the
engine! Obtain technical assistance.
Natural gas
3 V
alid for: vehicles with natural gas engines
Natural gas can be compressed or in liquid
form, addition to others.
Use of compressed natural gas (CNG)
Vehicles with a natural gas engine must only
be working with CNG (Compressed Natural
Gas CNG ), or with a mixture of biomethane
if it complies with Regulation EN 16723-2.
Fuels such as liquefied natural gas (LNG), liq-
uefied petroleum gas (LPG) or hithane (mix-
ture of hydrogen and methane) should not be
used to fill the tank.
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.
The engine management automatically
adapts to the natural gas used according to
its quality. Therefore, different quality gases
can be mixed in the tank, without the need for
