Several warning and control lamps light up
for a few seconds when the ignition is switch-
ed on, signalling that the function is being
verified. They will switch off after a few sec-
onds.
CAUTION
Always pay attention to any lit control lamps
and to the corresponding descriptions and in-
structions to avoid damage to the vehicle. Note
While the control lamps  or
 maintain lit
up, the engine will present faults, a higher consumption of fuel and a loss of engine
power.
Catalytic converter
The catalytic converter permits the subse-
quent treatment of the exhaust gases thus
reducing contaminating gas emissions. To
ensure a longer working life for the exhaust
system and catalytic converter in a petrol en-
gine:
● Always use unleaded petrol.
● Never run the fuel tank completely dry.
● Do not top up with too much engine oil
››› page 146 .
● Do not t

ow-start the vehicle; use the starter
cables ››› page 181.
If

you should notice misfiring, uneven run-
ning or loss of power when the car is moving,
reduce speed immediately. Have the car in-
spected by a specialised workshop. If this
happens, unburnt fuel can enter the exhaust
system and escape into the atmosphere. The
catalytic converter can also be damaged by
overheating. For the sake of the environment
Even when the emission control system is
working perfectly, there may be a smell of
sulphur under certain conditions. This de- pends on the sulphur content of the fuel
used.
Driving abroad
In some countries, certain safety regulations
and requirements are in force relating to ex-
haust gas emissions, which differ from the
technical characteristics of the vehicle. Be-
fore travelling abroad, SEAT recommends you
consult a technical service about the legal re-
quirements and the following points:
●
Does the vehicle need technical modifica-
tions for driving abroad, for example, adjust-
ment of the headlamps?
● Does the vehicle have all the tools, diag-
nostics equipment and spare parts required
for inspections and repairs?
● Are there any SEAT dealers in the destina-
tion country?
● For petrol vehicles: Is unleaded petrol avail-
able at the right octane rating?
● For diesel engines: is diesel fuel available
with a low sulphur content?
● Are a suitable engine oil ( ››› page 146) and
other engine fluids complying with SEAT
specifications available in the destination
country?

Fuel Introduction You will find a factory-fitted sticker containing
information on the type of fuel for your vehi-
cle on the inside of the fuel tank flap.
WARNING
Refuelling or handling fuel carelessly can
cause an explosion or fire resulting in serious
burns and injuries.
● Fuel is a highly explosive, easily flammable
substance.
● Observe current safety instructions and lo-
cal regulations concerning the handling of
fuel. Types of fuel
The type of fuel to use when refilling will de-
pend on the vehicle's engine. You will find a
factory-fitted sticker containing information
on the type of fuel for your vehicle on the in-
side of the fuel tank flap.
SEAT recommends the use of sulphur-free or
low sulphur fuel to reduce consumption and
prevent engine damage.Possible

Petrol Petrol types
Vehicles with petrol engines must refuel us-
ing unleaded petrol according to European
norm EN 228
››› .
Petrol types are categorised according to
their octane number (e.g. 91, 95, 98 or 99
RON (RON = “Research Octane Number”).
You may use petrol with a high octane num-
ber than the one recommended for your en-
gine. However, this has no advantage in
terms of fuel consumption and engine power.
SEAT recommends refuelling with a low sul-
phur content or sulphur-free petrol to reduce
fuel consumption for petrol engines. Petrol additives
The quality of the fuel influences the behav-
iour, power and service life of the engine.
This is why the petrol you use should carry
suitable additives already included by the
petrol industry, free of metals. These addi-
tives will help to prevent corrosion, keep the
fuel system clean and prevent deposits from
building up in the engine.
If good-quality petrol with metal-free addi-
tives is not available or engine problems
arise, the necessary additives must be added
when refuelling
››› .
Not all petrol additives have been shown to
be effective. The use of unsuitable petrol ad-
ditives may cause significant damage to the
engine and the catalytic converter. Metal ad-
ditives should never be used. Metal additives
may also be contained in petrol additives for
improving anti-detonation ratings or octane
ratings ››› .
SEAT recommends “genuine Volkswagen
Group Fuel Additives for petrol engines”.
These additives can be bought at SEAT deal-
ers, where information on how to use them
can also be obtained. CAUTION
● Do not refuel if the filler indicates that the
fuel contains metal. LRP (lead replacement
petrol) fuels contain high concentrations of » 137

metal additives. Using them may damage the
engine!
● Only use fuel with an octane rating that is
in line with the norm EN 228, otherwise sig-
nificant damage could be caused to the en-
gine and fuel system. Furthermore, it could
lead to a loss of performance with the conse-
quent engine fault.
● The use of unsuitable petrol additives could
seriously damage the engine and the catalyt-
ic converter.
● If, in exceptional circumstances, petrol with
a lower octane rating to that recommended is
used, only use moderate engine speeds and a
light throttle. Avoid using full throttle and
overloading the engine. Otherwise engine
damage may occur. Fill up with fuel of a suita-
ble octane rating as soon as possible.
● Just filling one full tank of leaded fuel or
with other metal additives would seriously
impair the efficiency of the catalytic convert-
er and could damage it. Natural gas
Natural gas, in addition to others, can be in
liquid form.
Liquefied natural gas (LNG) is the result of
heavy cooling of natural gas. Therefore its
volume is considerably reduced compared
with compressed natural gas (CNG). In vehi-
cles with a natural gas engine, liquefied nat-
ural gas cannot be directly refilled, as the gas would expand excessively in the vehicle gas
tank.
Therefore, vehicles with a natural gas engine
must only be refuelled using compressed
natural gas
››› .
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
one 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.
Natural gas and safety
If you can smell gas or suspect that there is a
leak ››› :
● Stop the vehicle immediately. ●
Switch the ignition off.
● Open the doors to appropriately ventilate
the vehicle.
● Immediately extinguish cigarettes.
● Move away from the vehicle or switch off
objects that may cause sparks or a fire.
● If you continue to smell gas, do not contin-
ue driving!
● Seek specialist assistance. Have the fault
repaired. WARNING
Failure to act when you can smell gas in the
vehicle or when refuelling can cause serious
injuries.
● Carry out the necessary operations.
● Leave the danger zone.
● If necessary, warn the emergency services. WARNING
The vehicle is not prepared to use liquefied
natural gas (LNG) and this fuel must not be
added under any circumstances. Liquefied
natural gas can cause the natural gas tank to
explode, resulting in serious injury. Note
The natural gas system must be subject to
regular inspections at a specialised work-
shop in accordance with the Maintenance
Programme. 138
