d the instructions on how to use the natu-
ral gas pump carefully.
The vehicle is not prepared for refuelling with
liquefied natural gas (LNG) ››› . Before refu-
el lin
g w
ith natural gas, make sure you add
the appropriate type of fuel ››› page 258.
Opening the fuel tank cap
The natural gas filler mouth is behind the fuel
tank cap, next to the petrol filler mouth.
● Unlock the vehicle with the key or with the
central
locking button situated on the driv-
er door ››

page 116.
● Press on the rear area of the flap and open
it.
Ref
uelling
Special feature: if the ambient temperature is
very high, the natural gas pump protection
against overheating disconnects this auto-
matically.
● Remove the plug from the gas filler mouth
›››
Fig. 239 1 .
● Connect the pump filling nozzle to the gas
fi l
l
er mouth.
● The fuel tank will be full when the p
ump
compressor automatically cuts the supply. ●
If y
ou wish to finish refuelling in advance,
press the button on the pump to stop the
flow.
Closing the fuel tank cap
● Check that the gas filler mouth retainer 2 is not trapped with the filler nozzle. If neces-
s
ar
y
, place it in the filler mouth again.
● Insert the plug in the filler mouth.
● Close the tank flap. Make sure you hear it
click
into place. WARNING
Natural gas is a highly explosive, easily flam-
mab l
e substance. Incorrect handling of the
natural gas can cause accidents serious
burns and other injuries.
● Before refuelling with natural gas, engage
the fillin
g mouth correctly. If you can smell
gas, stop refuelling immediately. 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 fil lin
g nozzles of natural gas pumps
can differ in the way they are operated. If you do not know, ask a qualified employee at the
petro
l
station to do the refuelling.
● Noises heard when refuelling are normal
and do not indicat
e the presence of a fault in
the system.
● The vehicle natural gas system is prepared
both for ref
uelling with a small compressor
(slow refuel) and a large compressor (fast re-
fuel) in natural gas service stations. Fuel
Ty
pe
s of petrol The correct grade of petrol is listed inside the
f
uel
t
ank flap.
The vehicle is equipped with a catalytic con-
verter and must only be run on unleaded pet-
rol. The petrol must comply with European
Standard EN 228 or German standard DIN
51626-1 and must be unleaded. You can re-
fuel with a maximum ethanol proportion of
10 % (E10). The types of petrol are differenti-
ated by their octane rating (RON).
The following titles appear on the corre-
sponding adhesive on the fuel tank flap:

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

Checking the brake fluid level
The brake fluid level must be between the
MIN and MAX markings.
However, if the brake fluid level goes down
noticeably in a short time, or drops below the
MIN mark, there may be a leak in the brake
system. Seek specialist assistance. A warn-
ing light on the instrument panel display
monitors the brake fluid level ››› page 109. »
