the following points:

–

Never ﬁll fuel into the spare fuel canister

The correct fuel grade for your vehicle is given

on a sticker on the inside of the fuel tank

ﬂap. Further notes on fuel can be found at

››› page 246.

Petrol with ethanol (“E” stands for Ethanol).

The number indicates the percentage of

ethanol in the petrol:

“E5” means an ethanol ratio of 5% max.

“E10” means an ethanol ratio of 10% max.

“E20” means an ethanol ratio of 20% max.

Super unleaded petrol 95 octane petrol or

normal 91 octane petrol at least

We recommend refuelling with super 95 octane

petrol (91 AKI). If not available, normal 91 oc-

tane petrol (87 AKI) (with a slight power loss)

may be used.

The capacity of your vehicle's fuel tank is given

in ››› page 319.

number indicates the maximum percent-

You should use super 95 octane petrol (91 AKI)

If super petrol is not available, if necessary, use

only use moderate engine speeds and a light

throttle. Refuel with super as soon as possible.

The vehicle is equipped with a catalytic con-

verter and must only be run on unleaded pet-

rol. The petrol must comply with the standard

EN 228 and be sulphur-free. Follow the regula-

tions of the country you are driving in. The types

of petrol are dierentiated by using the octane

numbers (RON) or via the anti-knock index

(AKI).

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.

Introduction

●

A single refuelling with leaded fuel or other

metal additives entails a permanent deterio-

ration of the eꢀectiveness of the catalytic

converter.

WARNING

Vehicles with Totalﬂex engine can run with un-

leaded petrol (95 octane / 91 AKI) according

to ANP No. 57 and with fuels with any high per-

centage of ethanol. The vehicle is refuelled in

the same way as petrol refuelling.

Due to the high temperatures reached by the

exhaust gas scrubbing system, you should

not park your vehicle near a surface that can

catch ﬁre easily. Fire hazard!

●

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.

Also consider that ››› page 246, Type of pet-

rol.

Do not apply wax underneath the vehicle

around the area of the exhaust system: Fire

metal additives. Risk of engine damage!

●

Only use unleaded petrol with petrol en-

gines.

Note

●

Never run the fuel tank dry.

●

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.

level.

Always adjust your speed to suit the weather

conditions, roads, braking distance and traf-

ﬁc if the particulate ﬁlter is in its regeneration

phase. Route recommendations should never

make you disregard each country's speciﬁc

trac regulations.

The particulate ﬁlter eliminates most of the

soot from the exhaust gas system. Under nor-

mal driving conditions the ﬁlter cleans itself.

If the ﬁlter does not clean itself (e.g. if short

journeys are made continuously), it becomes

blocked with soot and the following indication is

displayed to the driver:

●

Never tow the vehicle to start it, use jump

leads if necessary ››› page 252.

If you should notice misﬁring, uneven running or

loss of power when the car is moving, have the

vehicle inspected by a specialised workshop.

In general, the emissions warning lamp will

light up when any of these symptoms occur. If

this happens, any unburnt fuel can enter the ex-

haust system and escape into the atmosphere.

The catalytic converter can also be damaged

by overheating.

NOTICE

Particulate filter: cleaned

while the vehicle is moving. See

Manual.

●

When the exhaust system detects that the

particulate ﬁlter is close to saturation, the

self-cleaning function of this system recom-

mends optimal driving for this function.

The particulate ﬁlter needs cleaning (regenera-

tion).

●

Due to the high temperatures caused by

the regeneration of the particulate ﬁlter, it is

possible that the radiator fan will activate af-

ter stopping the engine, even it its operating

temperature has not been reached.

Regeneration of the petrol particulate ﬁlter

NOTICE

Requirements for the regeneration journey: the

engine is at operating temperature.

Never run the fuel tank completely dry be-

cause an irregular fuel supply can cause ig-

nition faults. This allows unburnt fuel to enter

the exhaust system, which could cause over-

heating and damage the catalytic converter.

For the sake of the environment

●

End the regeneration journey once the con-

trol warning lamp has gone out.

Even when the emission control system is

working perfectly, there may be a smell of

sulphur from the gases on occasions. This

depends on the sulphur content of the fuel

used. This can quite often be avoided by

changing to another brand of fuel.

If the warning lamp stays on after 30 minutes

of running in regeneration mode, have a speci-

alised workshop repair the fault.
