Group Fuel Additives for petrol engines”.
These additives can be bought at SEAT deal-

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
metal additives. Using them may damage the
engine!
● Never refuel with fuels containing a large
proportion of
ethanol (for example, E50, E85).
This could damage the fuel system.
● Just filling one full tank of leaded fuel or
fuel c
ontaining other metal additives would
seriously impair the efficiency of the catalytic
converter. ●
Only u

se fuel additives that have been ap-
proved by SEAT. Octane boosting or anti-
knock additives may contain metal additives
that could seriously damage the engine or
the catalytic converter. These additives must
not be used.
● High engine speed and full throttle can
damag
e the engine when using petrol with an
octane rating lower than the correct grade for
the engine. Note
● You m a

y use petrol with a high octane num-
ber than the one recommended for your en-
gine.
● In those countries where unleaded petrol is
not avai
lable, you may refuel with a fuel with
a low lead content. Diesel fuel
Please note the information on the inside of
the f
uel
t

ank flap.
We recommend the use of diesel fuel which
complies to European standard EN 590. If
diesel fuel which meets European standard
EN 590 is not available, the Cetane number
(CZ) must, at minimum, be 51. If the engine
is equipped with a particulate filter, the sul- phur content of the fuel must be below 50
parts

per million.
Winter-grade diesel
Summer fuel becomes thicker in winter and it
is more difficult to start the engine. For this
reason, petrol stations in some countries al-
so offer winter diesel with improved fluidity
when cold (winter-grade diesel).
Water in the fuel filter 1)
If your vehicle has a diesel engine and is
equipped with a fuel filter with a water sepa-
rator, the instrument panel may display the
following warning:  Water in the
fuel filter. If this is the case, take the
vehicle to a specialised workshop so that
they can drain the fuel filter. CAUTION
● The v ehic

le is not designed for the use of
FAME fuel (biodiesel). The fuel system would
be damaged if you used biodiesel.
● Do not mix fuel additives, the so-called
“thinners”, petro
l or similar additives with
diesel fuel.
● If poor-quality diesel fuel is used, it may be
neces
sary to drain the fuel filter more fre-
quently than is specified in the Maintenance
Programme. We recommend having this done 1)

table on page 2
Natural gas
Natural gas can be compressed or in liquid
form, addition to others.
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 ››› .
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
wil

l 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
a single 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.
Updated information relating to natural gas
quality is displayed on the instrument panel
›››  page 31.
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 v
ehic

le.
● Extinguish cigarettes immediately.
● 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 drivin g! ●
Seek s pec

ialist assistance. Have the fault
repaired. 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
Have the natural gas system checked regular-
ly b y

a specialised workshop, according to
the Maintenance Programme. 245

Checking and refilling levels
could d amage the engine. If there is no
c oo
lant in the expansion tank, do not con-
tinue driving. You should obtain professio-
nal assistance ››› .
– If there is still some coolant in the expan-
sion t
ank, t

op up to the upper mark.
– Top up with coolant until the level becomes
stab

le.
– Screw the cap back on correctly.
Any lo
ss of coolant fluid normally indicates a
leak in the cooling system. Take the vehicle
straight to a specialised workshop to have
the cooling system examined. If there are no
leaks in the engine cooling system, a loss of
coolant can only occur if the coolant boils
and is forced out of the system as a result of
overheating. WARNING
● The coo lin

g system is under pressure. Do
not unscrew the cap on the coolant expan-
sion tank when the engine is hot: risk of
burns!
● The antifreeze and coolant fluid can be a
health h
azard. Therefore, the antifreeze
should be stored in the original container in a
safe place out of reach of children. Failure to
comply could result in poisoning.
● If working inside the engine compartment,
remember that, ev
en when the ignition is
switched off, the radiator fan may start up au- tomatically, and therefore there is a risk of in-
jury
. WARNING
If there is not enough anti-freeze in the cool-
ant sys

tem, the engine may fail leading to se-
rious damage.
● Please make sure that the percentage of
additiv
e is correct with respect to the lowest
expected ambient temperature in the zone in
which the vehicle is to be used.
● When the outside temperature is very low,
the cool
ant could freeze and the vehicle
would be immobilised. In this case, the heat-
ing would not work either and inadequately
dressed passengers could die of cold. CAUTION
Do not top up the expansion tank with cool-
ant fluid if it

is empty! Air could enter the
cooling system. In this case, stop driving.
Seek specialist assistance. Otherwise, there
is a risk of engine damage. CAUTION
The original additives should never be mixed
with c oo

lants which are not approved by
SEAT. Otherwise, you run the risk of causing
severe damage to the engine and the engine
cooling system.
● If the fluid in the expansion tank is not pur-
ple b
ut is, for example, brown, this indicates that the G13 additive has been mixed with an
ina
dequat

e coolant. The coolant must be
changed as soon as possible if this is the
case! This could result in serious faults and
engine damage. For the sake of the environment
Coolants and additives can contaminate the
en vir

onment. If any fluids are spilled, they
should be collected and correctly disposed
of, with respect to the environment. Brake fluid

.
● If the warning lamp  lights up
, stop im-
mediately and check the tyres.
● If the tyres are inflated at different pres-
sure
s or if a tyre pressure is too low, this will
increase tyre wear, negatively affecting vehi-
cle stability and increasing braking distan-
ces.
● If tyres are inflated at different pressures or
a tyre pr
essure is too low, a tyre may be dam-
aged and burst resulting in a loss of control
of the vehicle.
● The driver is responsible for ensuring that
all
of the vehicle tyres are correctly inflated
to the right pressure. The recommended tyre
pressure is indicated on the label
››› page 267.
● The tyre monitoring system can only oper-
ate corr
ectly if all of the tyres are inflated to
the correct pressure when cold.
● Driving with tyres at the wrong pressure
can dam
age them and result in an accident.
Ensure that the tyre pressures of all the tyres
correspond to the vehicle load.
● Before starting a journey, always inflate
tyre
s to the correct pressure.
● Tyres with insufficient pressure are subjec-
ted to mor
e flexing. Due to this, the tyre
could become excessively hot, causing tread
separation and also tyre blow-out.
● With an overloaded vehicle at high speed,
the tyre
s can overheat and burst resulting in
a loss of vehicle control. ●
Ty r

e pressures which are too high or too
low reduce the useful life of the tyre, affect-
ing vehicle performance.
● If a tyre has not been punctured and it does
not hav
e to be changed immediately, drive to
the nearest specialised workshop at a moder-
ate speed and have the tyre checked and in-
flated to the correct pressure. WARNING
