WARNING
Refuelling or handling fuel carelessly can cause an explosion or fire re-
sulting in serious burns and injuries.
● Fuel is a highly explosive, easily flammable substance.
● Observe current safety instructions and local regulations concerning
the handling of fuel.
Types of fuel
The type of fuel to use when refilling will depend on the vehicle's engine.
You will find a factory-fitted sticker containing information on the type of
fuel for your vehicle on the inside of the fuel tank flap.
SEAT recommends the use of sulphur-free or low sulphur fuel to reduce con-
sumption and prevent engine damage.

Petrol types
Vehicles with petrol engines must refuel using unleaded petrol according to
European norm EN 228 ⇒
.
Petrol 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 number than the one recommended for your engine. Howev-
er, this has no advantage in terms of fuel consumption and engine power.
SEAT recommends refuelling with a low sulphur content or sulphur-free pet-
rol to reduce fuel consumption for petrol engines.
Petrol additives
The quality of the fuel influences the behaviour, performance and service
life of the engine. This is why the petrol you use should carry suitable addi-
tives already included by the petrol industry, free of metals. These additives
will help to prevent corrosion, keep the fuel system clean and prevent de-
posits from building up in the engine.
If good quality petrol with metal-free additives is not available or engine
problems arise, the necessary additives must be added when refuelling
⇒
.
Not all petrol additives have been shown to be effective. The use of unsuita-
ble petrol additives may cause significant damage to the engine and the
catalytic converter. Metal additives should never be used. Metal additives
may also be contained in petrol additives for improving anti-detonation rat-
ings or octane ratings ⇒
.
SEAT recommends “genuine Volkswagen Group fuel additives for petrol en-
gines”. These additives can be bought at SEAT Authorised Services, where
information on how to use them can also be obtained.

Checking and refilling levels
CAUTION
● Do not refuel 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!
● Only use fuel with an octane rating that is in line with the norm EN 228,
otherwise significant damage could be caused to the engine and fuel sys-
tem. Furthermore, it could lead to a loss of performance with the conse-
quent engine fault.
● The use of unsuitable petrol additives could damage the engine.
● If, in exceptional circumstances, petrol with a lower octane rating to that
recommended is used, only use moderate engine speeds and a light throt-
tle. Avoid using full throttle and overloading the engine. Otherwise you may
damage the engine. Fill up with fuel of a suitable octane rating as soon as
possible.
● Just one full tank of leaded fuel would seriously impair the efficiency of
the catalytic converter and could damage it.
Diesel
Diesel fuel
Diesel fuel must correspond to European standard EN 590 (in Germany,
EN 590 or DIN 51628).
The use of diesel fuel with a high sulphur percentage requires shorter serv-
ice intervals ⇒ Booklet Maintenance Programme ⇒
. Your Technical Serv-
ice will be able to tell you which countries have diesel with a high sulphur
content.
Do not mix fuel additives (thinners, or similar additives) with diesel fuel.
Winter-grade diesel
When using “summer-grade diesel fuel”, difficulties may be experienced at
temperatures below 0 °C (+32 °F) because the fuel thickens due to wax sep- aration. For this reason, “winter-grade diesel fuel” is available in Germany,
for example, during the cold months. It can be used at temperatures as low
as -20 °C (-4 °F).
In countries with different climatic conditions, other types of diesel fuel are
available that are suitable to local temperatures. Technical Services and fill-
ing stations in the country concerned will inform you on the type of diesel
fuels available.
A cold diesel engine makes more noise during winter temperatures than
summer temperatures. Furthermore, the exhaust gases may turn slightly
bluish while the engine is heating. The quantity of exhaust gases will de-
pend on the outside temperature.
Filter pre-heater
Vehicles with a diesel engine are fitted with a fuel filter pre-heating system.
This ensures that the fuel system remains operational to approx. -24 °C
(-11.2 °F), provided you use winter-grade diesel which is safe to -15 °C
(+5,0 °F).
However, if the fuel has waxed to such an extent that the engine will not
start at temperatures of under -24 °C (-11.2 °F), simply place the vehicle in a
warm garage or workshop for a while to heat up.
Auxiliary heater
Vehicles with a diesel engine may be fitted with an auxiliary heater. The
heater runs off the fuel from the fuel tank. On doing so, smells and steam
may be noticed outside the vehicle for a short period. This is normal and it
is not an indication of a fault in the vehicle.
Whenever there is little fuel in the tank (reserve), the auxiliary heater auto-
matically switches off.

WARNING
Never use start boosters. An aerosol start booster could explode or cause
a sudden rise in engine speed leading to engine damage and serious in-
jury.
CAUTION
● The vehicle is not prepared for the use of biodiesel. Never, under any
circumstances refuel with biodiesel. It could damage the fuel system and
subsequently lead to engine faults!
● The addition of biodiesel to diesel by the diesel producer according to
Standard EN 590 or other equivalent (DIN 51628 in Germany, for example)
is authorised and causes no type of damage to the engine or the fuel sys-
tem.
● The diesel engine has been designed for to use diesel fuel exclusively.
Therefore, never use petrol, fuel oil or other unsuitable fuels. The composi-
tion of these fuels may significantly damage the fuel system and the en-
gine.
● The use of diesel fuels with a high sulphur percentage could considera-
bly reduce the service life of the diesel particulate filter. Your Technical Serv-
ice will be able to tell you which countries have diesel with a high sulphur
content.
Information on fuel consumption
The consumption and emission values indicated do not refer to one specific
vehicle. They are only to be used to compare the values of the different ve-
hicle versions. The fuel consumption and CO 2 emissions of a vehicle not on-
ly depend on the effective use of fuel. They also depend on your driving
style and other non-technical factors. Calculation of fuel consumption
Fuel consumption and emission values are determined according to the cur-
rent version of the 715/2007/EC or 80/1268/EEC regulation and are valid
for the vehicle kerb weight. The specifications do
not refer to an individual
vehicle. Two measuring cycles are carried out on a rolling road test bed to
calculate fuel consumption. The test criteria are as follows:
Urban cycleMeasurement of the urban cycle starts with an engine cold
start. City driving is then simulated at between 0 and 50 km/
h (31 mph).
Road cycle
In the road cycle simulation, the car undergoes frequent ac-
celeration and braking in all gears, as in normal everyday
driving. The road speed ranges from 0 to 120 km/h
(75 mph).
CombinedThe average combined consumption is calculated with a
weighting of around 37 % for the urban cycle and 63 % for
the road cycle.
CO 2 emis-
sions of the
combinationThe exhaust gases are collected during both driving cycles
to calculate carbon dioxide emissions (urban and road). The
gas composition is then analysed to evaluate the CO 2 con-
tent and other emissions.
Note
● The kerb weight may vary according to the vehicle equipment. This
could raise consumption and the CO 2 emissions slightly.
● In practice, consumption values could be different to the values calcula-
ted based on the 715/2007/EC or 80/1268/EEC regulations.

Introduction
The AdBlue fill level must be checked when the vehicle is being serviced.
Additional information and warnings:
● Luggage compartment ⇒ page 127
● Fuel ⇒ page 271
● Wheels and tyres ⇒ page 297
● Accessories, parts replacement, repairs and modifications ⇒ page 261
WARNING
If the AdBlue fill level is too low, the vehicle may not restart after switch-
ing the ignition off. The emergency start or jump start will not be possi-
ble either!
● Top up with AdBlue at the latest 1000 km (600 miles) before it runs
out.
● Do not allow the AdBlue to run too low.
WARNING
AdBlue is an irritant, corrosive liquid that can cause injuries if it touches
the skin, eyes or respiratory organs.
● If AdBlue get in contact with eyes and skin, rinse for at least 15 mi-
nutes with plenty of water and seek medical help.
● If the AdBlue is swallowed, wash your mouth with plenty of water for
at least 15 minutes. Do not try to provoke vomiting unless recommended
by a Doctor. Seek medical advice immediately.
CAUTION

Several warning and control lamps should light up for a few seconds when
the ignition is switched on, signalling that the function is being verified.
They will switch off after a few seconds.
WARNING
If the warning lamps and messages are ignored, the vehicle may stall in
traffic, or may cause accidents and severe injuries.
● Never ignore the warning lamps or text messages.
● Stop the vehicle safely as soon as possible.
CAUTION
Failure to heed the control lamps and text messages when they appear may
result in faults in the vehicle.
Information on AdBlue
In vehicles with Selective Catalytic Reduction, a special urea solution (AdBl-
ue) is injected into the exhaust gas system in front of the catalytic converter
to reduce nitrogen oxide emissions. The consumption of AdBlue depends on individual driving style, the tem-
perature at which the system operates and the outside temperature where
the vehicle is driven.
AdBlue is kept in an independent tank in the vehicle and should be refilled
at an official supplier. The AdBlue tank holds about 17 litres.
A message will be displayed on the dash panel around 2400 km
(1500 miles) before the next service to indicate that AdBlue must be refilled
⇒ page 277. If you ignore this message and do not refill, you will be unable
to start the engine afterwards
⇒ page 275.
SEAT recommends contacting a specialised workshop. If you are unable to
visit a qualified specialised workshop, you should temporarily refill with a
minimum of 10.0 litres of AdBlue. Only refill using AdBlue expressly ap-
proved by SEAT.
When the indicators and light simultaneously, there is a fault. SEAT
recommends visiting the closest specialised workshop.

WARNING
If the vehicle moves unexpectedly, this could cause serious injury.
● Never work underneath the vehicle if it is not secured against moving.
If you must work underneath the vehicle with the wheels in contact with
the ground then it should be parked on flat ground, the wheels should be
prevented from moving and the key must be removed from the ignition.
● If you have to work underneath the vehicle, you must use suitable
stands additionally to support the vehicle, there is a risk of accident!.
The jack is not intended for this kind of work and its failure could lead to
severe injuries.
WARNING
The engine compartment is a dangerous area capable of causing serious
injury.
● For all type of work, always take the utmost precautions, work care-
fully and note the general safety standards in force. Never take personal
risks.
● Never work on the engine or in the engine compartment if you are not
familiar with the necessary operations. If you are not sure about proce-
dures then visit a specialised workshop to carry out the necessary work.
Incorrect work can cause serious injuries.
● Never open the bonnet if you see steam or coolant escaping from the
engine compartment. Hot vapours and coolant can cause serious burns.
Always wait until you cannot see or hear the sound of steam or coolant
coming from the engine compartment.
● Always allow the engine to cool down before opening the bonnet.
● Contact with hot elements of the engine and the exhaust system can
cause burns.

280Checking and refilling levels
WARNING (Continued)
● Once the engine has cooled, follow the instructions below before
opening the bonnet:
–Turn on the electronic parking brake and place the gear selector
lever in P or the gearbox lever in neutral.
– Remove the key from the ignition.
– Keep children away from the engine compartment and never leave
them unsupervised.
● When the engine is warm or hot, the cooling system is pressurised.
Do not unscrew the cap on the expansion tank when the engine is hot.
Otherwise, coolant may spray out under pressure causing burns and seri-
ous injury.
–Carefully and slowly unscrew the cap anticlockwise, gently press-
ing down on it.
– Always protect your face, hands and arms from hot coolant and
steam using a large, thick cloth.
● When refilling liquids, avoid spilling them on parts of the engine and
the exhaust system. Spilled liquids could cause a fire.
WARNING
The high voltages of the electrical system can give electric shocks as well
as causing burns and serious injury and possibly even death!
● Never cause short circuits in the electrical system. The battery could
explode.
● To minimise the risk of electric shock and serious consequences
while the engine is running or starting the engine, note the following:
–Never touch the electrical wiring of the ignition system.
– Never touch electric cables or the gas discharge lamps.
WARNING
In the engine compartment, there are rotating parts that could cause se-
rious injury.
● Never place your hands on or near the radiator fan. Touching the rotor
blades could seriously harm you. The ventilator works according to the
engine temperature and could start suddenly even when the ignition is
turned off and the key is removed.
● 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 as well as from the high-voltage ignition system. Always work with
the utmost caution.
–Always make sure that no parts of your body, jewellery, ties, loose
clothing and long hair can be trapped by the rotating parts of the en-
gine. Before any work, remove ties and jewellery ( necklaces, etc), tie
longhair back and tie all items of loose clothing to your body to make
sure that they cannot be trapped by engine components.
– Take extreme caution when operating the accelerator and remain
attentive. The vehicle could move, even with the electronic parking
brake activated.
● Always make sure you have not left any objects, such as cloths or
tools, in the engine compartment. If any object is left in the engine com-
partment, this could cause malfunctions, engine faults and even a fire.
WARNING
Refill liquids and certain materials can catch fire easily in the engine
compartment, causing a fire and serious injury!
● Never smoke.
● Never work close to places exposed to flames or sparks.
