P etr
o

l 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 f

uel 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 al
l

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 ››› .
S EA
T r

ecommends “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 r ef

uel if the filler indicates that the
fuel contains metal. LRP (lead replacement
petrol) fuels contain high concentrations of 178

Checking and refilling levels
metal additives. Using them may damage the
engine!
● On ly
use fuel with an octane rating that is
in line with the norm EN 228, otherw
ise 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 oct
ane 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 meta
l 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
li
quid f
orm.
Li

quefied 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.
Theref

ore, vehicles with a natural gas engine
must only be refuelled using compressed
natural gas ››› .
Nat ur
a

l 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. ●
Sw it
c

h the ignition off.
● Open the doors to appropriately ventilate
the vehic
le.
● Immediately extinguish cigarettes.
● Move away from the vehicle or switch off
obj
ects that may cause sparks or a fire.
● If you continue to smell gas, do not contin-
ue driving!
● Seek

specialist assistance. Have the fault
repair
ed. WARNING
Failure to act when you can smell gas in the
vehic l

e 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
nat ur

al 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
re gu

lar inspections at a specialised work-
shop in accordance with the Maintenance
Programme. 179

xplosion or fire resulting in serious
burns and injuries.
● Always make sure that you correctly close
the fuel c
ap to avoid evaporation and fuel
spillage.
● Fuels are highly explosive and inflammable
subs
tances that can cause serious burns and
injuries.
● Fuel could leak out or be spilt if the engine
is not
switched off or if the filler fuel nozzle is
not fully inserted into the tank filler neck
when refuelling. This could lead to a fire, ex-
plosion and severe injuries.
● When refuelling, turn off the engine and
turn off the ignition f
or safety reasons.
● Always turn off mobile telephones, radio
appar
atus and other radio wave emitting
equipment before refuelling. Electromagnetic
waves could cause sparks and lead to a fire.
● Never enter the vehicle while refuelling. If it
is ab
solutely necessary to enter, close the
door and touch a metal surface before touch- ing the filler nozzle again. This will prevent
the gener
ation of

static electricity. Sparks
could cause a fire when refuelling.
● Never handle fuel close to flames, sparks or
obj
ects with slow combustion (e.g. ciga-
rettes).
● Avoid static electricity and electro-magnet-
ic ra
diation when refuelling.
● Observe the safety regulations of the serv-
ice st
ation.
● Never spill fuel on the vehicle or in the lug-
gage c
ompartment. WARNING
For safety reasons, SEAT does not recommend
carr y

ing a spare fuel canister in the vehicle.
Fuel could be spilled and catch fire, above all
in case of an accident and this applies to a
full container as well as empty containers.
This could lead to explosions, fires and inju-
ries.
● Observe the following if you exceptionally
have t
o carry fuel in a canister:
– Never place a fuel container, to fill it, in-
side the vehicle or on the vehicle, for ex-
ample, in the luggage compartment. Fill-
ing in these circumstances could create
an electrostatic charge and spark that
could ignite fuel fumes.
– Always place the canister on the ground
to fill it. –
Inser t

the fuel nozzle into the neck of the
canister as far as possible.
– If you are using a metal fuel canister, the
nozzle must always touch the canister
while it is being filled to avoid static elec-
tricity.
– Follow the legal requirements for the use,
storage and transport of spare fuel canis- ters.
– Insure that the fuel container complies
with manufacturing standards, for exam-
ple, ANSI or ASTM F852-86. CAUTION
● Alw a

ys remove any fuel spilled anywhere
on the vehicle to avoid damage to the wheel
housing, the tyre and vehicle paintwork.
● Refuelling a petrol engine with diesel can
cause seriou
s engine and fuel system dam-
age; the resulting malfunctions are not cov-
ered by the SEAT warranty. If you refuel with
the wrong type of fuel, never start the engine.
This applies to even the smallest amount of
the wrong fuel. Seek specialist assistance.
With the engine running, the composition of
the wrong fuel could significantly damage the
