Checking and refilling levels
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
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 72 .
Nat ur
al 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.
● Extinguish cigarettes immediately.
● 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
Have the natural gas system checked regular-
ly by a specialised workshop, according to
the Maintenance Programme. 197

Engine oil General notes The engine comes with a special, multi-grade
oil that can be used all year round.
Because the use of high-quality oil is essen-
tial for the correct operation of the engine
and its long useful life, when topping up or
changing oil, use only those oils that comply
with VW standards.
The specifications (VW standards) set out in
the following page should appear on the con-
tainer of the service oil; when the container
displays the specific standards for petrol and
diesel engines together, it means that the oil
can be used for both types of engines.
We recommend that the oil change indicated
in the Maintenance Programme, be per-
formed by a technical service or specialised
workshop.
The correct oil specifications for your engine
are listed in the
›››
page 201, Oil properties .
Service intervals
Service intervals can be flexible (LongLife
service) or fixed (dependent on time/dis-
tance travelled).
If the PR code that appears on the back of the
Maintenance Programme booklet is PR QI6,
this means that your vehicle has the LongLife service programmed. If it lists the codes QI1,
QI2, QI3, QI4 or QI7, the interval service is
dependent on time/distance travelled.
Flexible service intervals (LongLife service
intervals*)
Special oils and processes have been devel-
oped which, depending on the characteris-
tics and individual driving profiles, enable
the extension of the oil change service (Long-
Life service intervals).
Because this oil is essential for extending the
service intervals, it
must only be used ob-
serving the following indications:
● Avoid mixing it with oil for fixed service in-
tervals.
● Only in exceptional circumstances, if the
engine oil level is too low ››› page 201 and
LongLife oil is not available, it is permitted to
top up (once) with oil for fixed service inter-
vals › ››
page 201 (up to a maximum of 0.5 li-
tres).
Fixed service intervals*
If your vehicle does not have the “LongLife
service interval” or it has been disabled (by
request), you may use oils for fixed service
intervals
, which also appear in ››› page 201,
Oil properties . In this case, your vehicle must
be serviced after a fixed interval of 1
year/15,000 km (10,000 miles)(whatever comes first)
››› Booklet Maintenance Pro-
gramme.
● In ex

ceptional circumstances, if the engine
oil level is too low ››› page 201 and you can-
not o

btain the oil specified for your vehicle,
you can add a small quantity of oil conform-
ing to the specification ACEA A2 or ACEA A3
(petrol engines) or ACEA B3 or ACEA B4 (die-
sel engines) (up to 0.5 l).
Vehicles with diesel particulate filter*
The Maintenance Programme states whether
your vehicle is fitted with a diesel particulate
filter.
Only VW 507 00 engine oil, with reduced ash
formation, may be used in diesel engines
equipped with particulate filter. Using other
types of oil will cause a higher soot concen-
tration and reduce the life of the DPF. There-
fore:
● Avoid mixing this oil with other engine oils.
● Only in exceptional circumstances, if the
engine oil level is too low ››› page 201 and
you cannot obtain the oil specified for your
vehicle, you can use a small quantity of oil
(once) conforming to the VW 506 00,
VW 506 01, VW 505 00, VW 505 01 or
ACEA B3/ACEA B4 specification. (up to 0.5 l).

Advice
Topping up engine oil Fig. 176
In the engine compartment: Engine
oil filler cap Read the additional information carefully
›››  page 31
Before opening the bonnet, read and observe
the warnings ››› in Work in the engine
compartment on page 198 .
The po s
ition of the oil filler opening is shown
in the corresponding engine compartment il-
lustration ››› page 198
.
Engine oil specification ››› page 200. WARNING
Oil is highly inflammable! Ensure that no oil
comes into contact with hot engine compo-
nents when topping up. CAUTION
If the oil level is above the area A do not
start the engine. This could result in damage
to the engine and catalytic converter. Contact
a specialised workshop. For the sake of the environment
The oil level must never be above area A .
Otherwise oil can be drawn in through the
crankcase breather and escape into the at-
mosphere via the exhaust system. Changing engine oil
The engine oil must be changed at the inter-
vals given in the service schedule.
We recommend that you have the engine oil
changed by a Technical Service.
The oil change intervals are shown in the
Maintenance Programme.
WARNING
Only change the engine oil yourself if you
have the specialist knowledge required!
● Before opening the bonnet, read and ob-
serve the warnings ››› page 198.
● Wait

for the engine to cool down. Hot oil
may cause burn injuries.
● Wear eye protection to avoid injuries, such
as acid burns, caused by splashes of oil. ●
When removing the oil drain plug with your
fingers, keep your arm horizontal to help pre-
vent oil from running down your arm.
● Wash your skin thoroughly if it comes into
contact with engine oil.
● Engine oil is poisonous! Used oil must be
stored in a safe place out of the reach of chil-
dren. CAUTION
No additives should be used with engine oil.
This could result in engine damage. Any dam-
age caused by the use of such additives
would not be covered by the factory warranty. For the sake of the environment
● Because of disposal problems and the spe-
cial tools and specialist knowledge required,
we recommend that you have the engine oil
and filter changed by a Technical Service.
● Never pour oil down drains or into the
ground.
● Use a suitable container when draining the
used oil. It must be large enough to hold all
the engine oil. 202

Checking and refilling levels
Check the water level in the windscreen
washer reservoir regularly and top up as re-
quired.
The container for the windscreen washer con-
tains the cleaning fluid for the windscreen,
the rear window and the headlight washer
system*.
● Open the bonnet  ››› page 198.
● The windscreen washer reservoir is marked
with the symbol  on the cap.
● Chec k
there is enough windscreen water in
the reservoir.
Recommended windscreen wipers
● For the hottest seasons we recommend
summer G 052 184 A1 for clear glass. Propor-
tions of the mixture in the washer fluid tank:
1:100 (1 part concentrate per 100 parts wa-
ter).
● All year round, G 052 164 A2 for clear
glass. Approximate proportion of the winter
mixture, up to -18°C (0°F): 1:2 (1 part con-
centrate per 2 parts water); otherwise, a 1:4
proportion of mixture in the washer fluid
tank.
Top-up quantities
The reservoir holds approximately 3 litres in
versions without headlight washer and 5 li-
tres in versions with headlight washer. WARNING
If the water from the windscreen washer does
not contain enough anti-freeze, it may freeze
on the windscreen and rear window, reducing
forward and rear visibility.
● In winter, ensure the windscreen washer
contains enough anti-freeze.
● In cold conditions, you should not use the
windscreen washer system unless you have
warmed the windscreen with the ventilation
system. The antifreeze could freeze on the
windscreen and reduce visibility. WARNING
Never mix an unsuitable antifreeze or other
similar additives with the windscreen washer
water. A greasy layer may be formed on the
windscreen which will impair visibility.
● Use clean water with a window cleaner rec-
ommended by SEAT.
● If necessary, add a suitable antifreeze to
the water in the reservoir. CAUTION
● Do not mix cleaning products recommen-
ded by SEAT with other products. This could
lead to flocculation and may block the wind-
screen washer jets.
● When topping up service fluids, make abso-
lutely certain that you fill the fluids into the
correct reservoirs. Using the wrong fluids could cause serious malfunctions and engine
damage!
● Not having windscreen wiper fluid reduces
visibility through the windscreen, and leads
to loss of visibility in headlights in models
with headlight washer. Battery
General information The battery is located in the engine compart-
ment and is almost
maintenance-free. It is
checked as part of the Inspection Service.
Nevertheless, check the terminals are clean
and have the correct tightening torque, espe-
cially in summer and winter.
Disconnecting the battery
The battery should only be disconnected in
exceptional cases. When the battery is dis-
connected, some of the vehicle's functions
are “lost” ( ››› table on page 206). These
functions will require resetting after the bat-
tery is reconnected.
Deactivate the anti-theft alarm* before you
disconnect the battery Otherwise the alarm
will be triggered. »
