Type of petrol
The correct grade of petrol is listed inside the
fuel tank ap.
The vehicle is equipped with a catalytic con-
verter and must only be run on unleaded pet-
rol. The petrol must comply with the stand-
ard EN 228 and be sulphur-free. Fuels with a
10% ethanol ratio can be refuelled (E10)
2)
. The
types of petrol are dierentiated by using the
octane numbers (RON) or via the anti-knock
index (AKI).
Unleaded super plus 98 octane petrol or su-
per 95 octane petrol at least
We recommend refuelling with super plus 98
octane petrol (93 AKI). If not available: super 95
octane petrol (91 AKI) (with a slight power loss).
If super petrol is not available, if necessary, use
normal 91 octane petrol (87 AKI). In this case
only use moderate engine speeds and a light
throttle. Refuel with super as soon as possible.
NOTICE
●
Fuels with a high percentage of ethanol,
e.g. E30 - E100 button must not be used. The
fuel system would be damaged.
●
A single refuelling with leaded fuel or other
metal additives entails a permanent deteri-
oration of the eectiveness of the catalytic
converter.
●
Only use fuel additives that have been ap-
proved by SEAT. The products that contain
substances to increase the octane rating or
decrease knocking may contain metal addi-
tives that damage the engine and catalytic
converter. This type of products must not be
used.
●
Do not use fuels shown in the pump as con-
taining 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 required by the engine can be used.
●
In countries in which there is no sulphur-
free fuel, it is also allowed to use low sulphur
content fuel.

Introduction
WARNING
Due to the high temperatures reached by the
exhaust gas scrubbing system, you should
not park your vehicle near a surface that can
catch re easily. Fire hazard!
WARNING
Do not apply wax underneath the vehicle
around the area of the exhaust system: Fire
hazard!
Catalytic converter
To maintain the useful life of the catalytic
converter
●
Only use unleaded petrol with petrol en-
gines.
●
Never run the fuel tank dry.
