Practical tips
Ethanol fuel
3 Applies to vehicles: with Totalflex engine
You can r
ecognise vehicles with Totalflex en-
gines
1)
by label on the fuel tank lid with 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

rol
Note
SEAT recommends filling the tank exclu-
sively with petrol e
very 10,000 km to de-
crease impurities that using E100 ethanol
fuel might have left in the engine.
Diesel
3 Applies to vehicl
es: with diesel engine
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-
tures, thus aff
ecting the start or operation of
the engine. To ensure that you can continue
to use your vehicle as usual, the diesel sold in
gas stations is provided -depending on the
station- with fluidity when cold. Ask the em-
ployee of the petrol station whether their die-
sel is suitable for use in winter and if it is suited
for current and future temperatures.
CAUTION
●
Never use of F
AME (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 Applies to vehicl
es: with a natural gas engine
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.
Do not use fuels such as liquefied natural gas
(Liquefied Natural Gas), liquified petroleum
gas (LPG = Liquefied Petroleum G) or hy-
thane (hydrogen mixed with methane)

.
Ther
ef
or
e, vehicles with a natural gas engine
must only be refuelled using compressed
natural gas (CNG).
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 propor-
tion of nitrogen and carbon dioxide can fluc-
tuate within the quality groups. Therefore, ve-
hicle consumption can also vary when using
a single type of gas only.
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
comprehensive draining before applying a
different quality gas.
