The safety of the LPG system guarantees operation without risk. The following
safety measures have been adopted:
•The LPG tank has a solenoid valve which closes automatically when the
engine is switched off (ignition off) or when running on petrol.•A solenoid type main valve disconnects the supply of gas to the engine
compartment when the engine is switched off or running on petrol.•A safety valve in the LPG tank with pipes to the outside prevents the gas
from entering the vehicle interior.•All anchorage points and materials have been designed to ensure the
maximum possible levels of safety.
The condition of the LPG system should be checked regularly to guarantee
safe driving conditions ⇒ . These checks are included in the Maintenance
Programme.WARNING
•If there is a smell of gas or a suspected leak, stop the vehicle immedi-
ately and switch off the ignition. Open the doors to ventilate the vehicle. Do
not carry on driving! Take the vehicle to a specialised workshop and have
the fault repaired.•Immediately extinguish any cigarettes and remove from the vehicle any
objects which might produce a spark or cause a fire, and switch off imme-
diately if gas is smelt or a leak is detected.•LGP tanks are subject to pressure and must be checked regularly. The
owner of the vehicle must check that these services are performed
correctly.•When parking the vehicle in a closed area (for example in a garage),
make sure that there is adequate ventilation, either natural or mechanical,
to neutralise the LPG in the event of a leak.
Note
For any fault in the LGP system, please refer to the SEAT web page, which lists
the workshops authorised to repair these faults.PetrolPetrol types
The correct petrol types are listed on a sticker inside the fuel
tank flap.Only unleaded petrol conforming to standard DIN EN 228 may be used for
vehicles with catalytic converters (EN = “European Standard”).
Fuel types are differentiated by the octane rating, e.g: 91, 95, 98 RON (RON
= “Research Octane Number”, unit for determining the knock resistance of
petrol). You may use petrol with a higher octane number than the one recom-
mended for your engine. However, this has no advantage in terms of fuel
consumption and engine power.
The correct fuel type for your vehicle is given in the technical table for the
engine, in the Technical Data section.
Caution
•Petrol with standard EN 228 may be mixed with small quantities of
ethanol. However, the so-called “bioethanol fuels” available at commercial
establishments with reference E50 or E85, which contain a high percentage
of ethanol, may not be used, as they will damage the fuel system.•Even one tankful of leaded fuel would permanently impair the efficiency
of the catalytic converter.

232•High engine speed and full throttle can damage the engine when using
petrol with an octane rating lower than the correct grade for the engine.For the sake of the environment
Just one full tank of leaded fuel would seriously impair the efficiency of the
catalytic converter.Petrol additives
Petrol additives improve the quality of the petrol.The quality of the petrol influences the performance, power and life of the
engine. For this reason, you should use good quality petrol containing addi-
tives. These additives will help to prevent corrosion, keep the fuel system
clean and prevent deposits from building up in the engine.
If good quality petrol with additives is not available or engine problems occur,
the required additives must be added during refuelling.DieselDiesel*Diesel fuel must conform to DIN EN 590 (EN = “European Standard”). It must
have a cetane number (CN) of at least 51. The cetane number indicates the
ignition quality of the diesel fuel.
Notes on refuelling ⇒page 226.
Biodiesel*
Caution
•Your vehicle is not designed to use biodiesel fuel. Never, under any
circumstances refuel with biodiesel. The use of biodiesel fuel could damage
the engine and the fuel system. The addition of biodiesel to diesel fuel by the
diesel manufacturer in accordance with standard EN 590 or DIN 51628 is
authorised and will not cause damage to the engine or the fuel system.•The diesel engine has been designed to be used exclusively with diesel
fu el con for m i ng to sta nda rd E N 59 0 . Never refuel or use petrol, kerosene, fuel
oil or any other type of fuel. If you accidentally fill up the vehicle with the
wrong type of fuel, do not start the engine. Seek assistance from specialised
personnel. The composition of these fuels may severely damage the fuel
system and the engine.Winter driving
Diesel can thicken in winter.Winter diesel
When using summer diesel fuel, difficulties may be experienced at tempera-
tures below 0 °C because the fuel thickens due to wax separation. Therefore,
winter diesel fuel is available in some countries during the cold months. It can
be used at temperatures as low as -22 °C.
In countries with different climatic conditions the diesel fuel generally sold
has different temperature characteristics. Check with an Authorised Service
Centre or filling stations in the country concerned regarding the type of diesel
fuels available.

Filter pre-heater
Your vehicle is fitted with a fuel filter glow plug system, making it well
equipped for operation in winter. This ensures that the fuel system remains
operational to approx. -24 °C, provided you use winter diesel which is safe to
-15 °C.
However, if the fuel has waxed to such an extent that the engine will not start
at temperatures of under -24 °C, simply place the vehicle in a warm place for
a while.
Caution
Do not mix fuel additives (thinners or similar products) with diesel fuel.Working in the engine compartmentSafety instructions on workin
g in the engine compartment
Any work carried out in the engine compartment or on the
engine must be carried out cautiously.Before starting any work on the engine or in the engine compart-
ment:
1. Switch off the engine and remove the key from the ignition.
2. Apply the handbrake.
3. Move the gear lever to neutral or the selector lever to position P.
4. Wait for the engine to cool down.
5. Keep children away from the vehicle. 6. Raise the bonnet
⇒page 235.
You should not do any work in the engine compartment unless you know
exactly how to carry out the jobs and have the correct tools! Have the work
carried out by a specialised workshop if you are uncertain.
All service fluids and consumables, e.g. coolant, engine oil, spark plugs and
batteries, are being constantly developed. SEAT provides a constant flow of
information to the Authorised Service Centres concerning modifications. For
this reason, we recommend you to have service fluids and consumables
replaced by an Authorised Service Centre. Please observe the relevant
instructions ⇒page 224. The engine compartment of the vehicle is a
hazardous area ⇒.
WARNING
All work on the engine or in the engine compartment, e.g. checking and
refilling fluids, involves a risk of injury and scalding as well as the risk of
accident or fire.•Never open the bonnet if you see steam, smoke or coolant escaping
from the engine compartment. Otherwise, there is a risk of sustaining
burns. Wait until no more steam or coolant is emitted, then allow the
engine to cool before carefully opening the bonnet.•Switch off the engine and remove the key from the ignition.•Apply the handbrake and move the gear lever to neutral or selector
lever to position P.•Keep children away from the vehicle.•Never touch hot engine parts. There is a risk of burns.•Never spill liquids on a hot engine or on a hot exhaust gas system. This
is a fire hazard.•Avoid causing short-circuits in the electrical system, particularly at the
points where the jump leads are attached ⇒page 283. The battery could
explode.

start automatically, even when the engine has been switched off and the
key removed from the ignition!•Do not unscrew the cap on the coolant reservoir when the engine is hot.
If the coolant is hot, the cooling system will be pressurised!•Protect face, hands and arms by covering the cap with a large, thick
cloth to protect against escaping coolant and steam.•Al wa ys m ake s u re yo u ha ve n o t l e f t a ny o bj e c t s , s u ch as cl e an i n g cl o t h s
and tools, in the engine compartment.•If you have to work underneath the vehicle, you must use suitable
stands additionally to support the vehicle, there is a risk of accident!. A
hydraulic jack is insufficient for securing the vehicle and there is a risk of
injury.•If any work has to be performed when the engine is started or with the
engine running, there is an additional, potentially fatal, safety risk from the
rotating parts, such as the drive belts, alternator, radiator fan, etc., and
from the high-voltage ignition system. You should also observe the
following points:
−Never touch the electrical wiring of the ignition system.
− Ensure that jewellery, loose clothing and long hair do not get
trapped in rotating engine parts. Da nger of death. Before starting any
work remove jewellery, tie back and cover hair, and wear tight-fitting
clothes.
− Never accelerate with a gear engaged without taking the necessary
precautions. The vehicle could move, even if the handbrake is applied.
Danger of death.•If work has to be carried out on the fuel system or on electrical compo-
nents, you must observe the following safety notes in addition to the above
warnings:
−Always disconnect the battery. The vehicle must be unlocked when
this is done, otherwise the alarm will be triggered. −
Do not smoke.
− Never work near naked flames.
− Always have a fire extinguisher on hand.
Caution
When topping up service fluids, make sure not to mistake them. Using the
wrong fluids could cause serious malfunctions and engine damage!
For the sake of the environment
Service fluids leaks are harmful to the environment. For this reason you
should make regular checks on the grou nd underneath your vehicle. If you
find spots of oil or other fluids, have your vehicle inspected at a specialised
workshop.

Engine oilGeneral notesThe engine comes with a special, high quality, multi grade oil that can be
used in all seasons of the year except for those regions affected by extreme
cold.
As the use of good quality oil is necessary for the correct operation and long
service life of the engine, when it becomes necessary to replenish or change
the oil, always use an oil that complies with VW standards.
The specifications (VW standards) set out in the following page should
appear on the container 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 performed by an Authorised Service Centre or a specialised
workshop. The correct oil specifications for your engine are listed in
⇒page 237, “Oil
properties”.
Service intervals
Service intervals can be flexible (LongLife service) or fixed (dependent on
time/distance travelled).
If the PR code that appears on the back of the Maintenance Programme
booklet is QG1, this means that your vehicle has the LongLife service
programmed. If it has the codes QG0 or QG2 the interval service is dependent
on time/distance travelled.
Flexible service intervals (LongLife*)
Special oils and processes have been developed which, depending on the
characteristics and individual driving profiles, allow to extend the oil change
service (LongLife service intervals).
Because this oil is essential for extending the service intervals, it must only
be used observing the following indications:
•Avoid mixing it with oil for fixed service intervals.•Only in exceptional circumstances, if the engine oil level is too low
⇒ page 237 and LongLife oil is not available, it is permitted to top up (once)
with oil for fixed service intervals ⇒ page 237 (up to a maximum of 0.5
litres).
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 237, “Oil properties”. In this case, your vehicle must be
serviced after a fixed interval of 1 year / 15,000 km (whatever comes first)
⇒ Booklet “Maintenance Programme”.•In exceptional circumstances, if the engine oil level is too low
⇒ page 237 and you cannot obtain the oil specified for your vehicle, you can
put in a small quantity of oil conforming to the specification ACEA A2 or
ACEA A3 (petrol engines) or ACEA B3 or ACEA B4 (diesel 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 concentration and reduce the life of the DPF. Therefore:
•Avoid mixing this oil with other engine oils.•Only in exceptional circumstances, if the engine oil level is too low
⇒ page 237 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).Oil properties
Engine oil additives
No type of additive should be mixed with the engine oil. The deterioration
caused by these additives is not covered by the warranty.
Note
Before a long trip, we recommend finding an engine oil that conforms to the
corresponding VW specifications and keeping it in the vehicle. This way, the
correct engine oil will always be available for a top-up if needed.Checking the engine oil level

Depending on how you drive and the conditions in which the vehicle is used,
oil consumption can be up to 0.5 l/1000 km. Oil consumption is likely to be
higher for the first 5000 km. For this reason the engine oil level must be
checked at regular intervals, preferably when filling the tank and before a
journey.
WARNING
Any work carried out in the engine compartment or on the engine must be
carried out cautiously.•When working in the engine compartment, always observe the safety
warnings ⇒page 233.
Caution
If the oil level is above the area do not start the engine. This could result
in damage to the engine and catalytic converter. Contact an Authorised
Service Centre.Topping up engine oil

WARNING
Oil is highly inflammable! Ensure that no oil comes into contact with hot
engine components when topping up.
Caution
If the oil level is above the area do not start the engine. This could result
in damage to the engine and catalytic converter. Contact a specialised work-
shop.
For the sake of the environment
The oil level must never be above area . Otherwise oil can be drawn in
through the crankcase breather and escape into the atmosphere via the
exhaust system.
Changing engine oil
The engine oil must be changed at the intervals given in the
service schedule.We recommend that you have the engine oil changed by an Authorised
Service Centre.
The oil change intervals are shown in the Maintenance Programme ⇒.
WARNING
Only change the oil yourself if you have the specialist knowledge required!•Before opening the bonnet, read and observe the warnings
⇒ page 233, “Safety instructions on working in the engine compartment”.•Wait for the engine to cool down. Hot oil may cause burn injuries.•Wear eye protection to avoid injuries caused by splashes of oil.•When removing the oil drain plug with your fingers, keep your arm hori-
zontal to help prevent 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 children.Caution
No additives should be used with engine oil. This could result in engine
damage. Any damage caused by the use of such additives would not be
covered by the factory warranty.
For the sake of the environment
•Because of the disposal problems, the necessary special tools and
specialist knowledge required, we recommend that you have the engine oil

240•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.CoolantCoolant specifications
Coolant is a mixture of water and at least 40% coolant addi-
tive.The cooling system must be filled with a mixture of water and at least 40 % of
our G 12+ additive or an additive with the TT-VW 774 F specification (it has a
purple colour). This mixture provides the necessary freeze protection down to
-25 °C and protects the alloy parts of the cooling system against corrosion. It
also prevents scaling and raises the boiling point of the coolant.
The concentration of coolant must always be at least 40% - even if freeze
protection is not required.
If greater freeze protection is required in very cold climates, the proportion of
the G 12+ additive can be increased. However, the percentage of coolant
add it iv es s ho uld n ot e xcee d 6 0% , as this wo u ld re d uce t he fr ee ze pro tec ti on.
It would also reduce the cooling effect. A mixture with 60% additive will give
antifreeze protection to approx. -40 °C.
WARNING
•The coolant additive is toxic. There is a toxic risk. Always keep the
coolant additive in the original container which should be stored out of the
reach of children. The same applies to coolant which you have drained off.
•The G 12+ additive must be added in sufficient quantities to provide
anti-freeze protection at the coldest ambient temperatures that can be
expected. At extremely cold outside temperatures, the coolant could
freeze, causing the vehicle to breakdown. As the heater would not work
either, there is a risk of freezing to death.Caution
•Other additives may give considerably inferior corrosion protection. The
resulting corrosion in the cooling system can lead to a loss of coolant,
causing serious damage to the engine.•The G 12+ additive (purple) can be mixed with the G 12 (red) or G 11 addi-
tive. Never mix G12 (red) with G 11.WARNING (continued)
