Practical tips
throttle. Refuel with super as soon as possi-
bl
e
.
CAUTION
Fuels high percent
age of ethanol, e.g.
E30 - E100 button must not be used. The
fuel system would be damaged. Exception:
vehicles with Totalflex engine

Ethanol fuel.
A single refuelling with leaded fuel or
other metal additives entails a permanent
deterioration of the effectiveness of the
catalytic converter.
Only use fuel additives that have been
approved by SEAT. The products that con-
tain substances to increase the octane rat-
ing or decrease knocking may contain met-
al additives that damage the engine and
catalytic converter. This type of products
must not be used.
Do not use fuels shown in the pump as
containing metals. LRP (lead replacement
petrol) fuels contain high concentrations of
metal additives. Risk of engine damage!
High engine speed and full throttle can
damage the engine when using petrol with
an octane rating lower than the correct
grade for the engine.
Note
Fuel with an octane rating higher than the
one r
equired by the engine can be used.
In countries in which there is no sulphur-
free fuel, it is also allowed to use low sul-
phur content fuel.
Ethanol fuel

You can r
ecognise vehicles with Totalflex en-
gines

the marking “Petrol/ethanol”.
Vehicles with Totalflex engine can run with
unleaded petrol (95 octane / 91 AKI) accord-

led in the same way as petrol refuelling.

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 vehicles: with diesel engine
Please not
e 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 affecting 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.
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 speci-
alised workshop so that they can drain the
fuel filter.
