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

Petrol Petrol types
Vehicles with petrol engines must refuel us-
ing 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 num-
ber than the one recommended for your en-
gine. However, this has no advantage in
terms of fuel consumption and engine power.
SEAT recommends refuelling with a low sul-
phur content or sulphur-free petrol to reduce
fuel consumption for petrol engines. Petrol additives
The quality of the fuel influences the behav-
iour, power and service life of the engine.
This is why the petrol you use should carry
suitable additives already included by the
petrol industry, free of metals. These addi-
tives will help to prevent corrosion, keep the
fuel system clean and prevent deposits from
building up in the engine.
If good-quality petrol with metal-free addi-
tives 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 unsuitable petrol ad-
ditives may cause significant damage to the
engine and the catalytic converter. Metal ad-
ditives should never be used. Metal additives
may also be contained in petrol additives for
improving anti-detonation ratings or octane
ratings ››› .
SEAT recommends “genuine Volkswagen
Group Fuel Additives for petrol engines”.
These additives can be bought at SEAT deal-
ers, where information on how to use them
can also be obtained. CAUTION
● Do not refuel if the filler indicates that the
fuel contains metal. LRP (lead replacement
petrol) fuels contain high concentrations of » 137

Filling the tank Introduction The fuel tank flap is on the rear right of the
vehicle.
WARNING
Refuelling or handling fuel carelessly can
cause an explosion or fire resulting in serious
burns and injuries.
● Always make sure that you correctly close
the fuel cap to avoid evaporation and fuel
spillage.
● Fuels are highly explosive and inflammable
substances that can cause serious burns and
injuries.
● Fuel could leak out or be spilt if the engine
is not switched off or if the filler fuel nozzle is
not fully inserted into the tank filler neck
when refuelling. This could lead to a fire, ex-
plosion and severe injuries.
● When refuelling, turn off the engine and
turn off the ignition for safety reasons.
● Always turn off mobile telephones, radio
apparatus and other radio wave emitting
equipment before refuelling. Electromagnetic
waves could cause sparks and lead to a fire.
● Never enter the vehicle while refuelling. If it
is absolutely necessary to enter, close the
door and touch a metal surface before touch- ing the filler nozzle again. This will prevent
the generation of static electricity. Sparks
could cause a fire when refuelling.
●
Never handle fuel close to flames, sparks or
objects with slow combustion (e.g. ciga-
rettes).
● Avoid static electricity and electro-magnet-
ic radiation when refuelling.
● Observe the safety regulations of the serv-
ice station.
● Never spill fuel on the vehicle or in the lug-
gage compartment. WARNING
For safety reasons, SEAT does not recommend
carrying a spare fuel canister in the vehicle.
Fuel could be spilled and catch fire, above all
in case of an accident and this applies to a
full container as well as empty containers.
This could lead to explosions, fires and inju-
ries.
● Observe the following if you exceptionally
have to carry fuel in a canister:
–Never place a fuel container, to fill it, in-
side the vehicle or on the vehicle, for ex-
ample, in the luggage compartment. Fill-
ing in these circumstances could create
an electrostatic charge and spark that
could ignite fuel fumes.
– Always place the canister on the ground
to fill it. –
Insert the fuel nozzle into the neck of the
canister as far as possible.
– If you are using a metal fuel canister, the
nozzle must always touch the canister
while it is being filled to avoid static elec-
tricity.
– Follow the legal requirements for the use,
storage and transport of spare fuel canis- ters.
– Insure that the fuel container complies
with manufacturing standards, for exam-
ple, ANSI or ASTM F852-86. CAUTION
● Always remove any fuel spilled anywhere
on the vehicle to avoid damage to the wheel
housing, the tyre and vehicle paintwork.
● Refuelling a petrol engine with diesel can
cause serious engine and fuel system dam-
age; the resulting malfunctions are not cov-
ered by the SEAT warranty. If you refuel with
the wrong type of fuel, never start the engine.
This applies to even the smallest amount of
the wrong fuel. Seek specialist assistance.
With the engine running, the composition of
the wrong fuel could significantly damage the
fuel system and the engine itself. For the sake of the environment
Fuels can contaminate the environment. Col-
lect any spilt service fluids and allow a pro-
fessional to dispose of them. 139Technical specifications

The warning lamp  switches off when the
natural gas is exhausted. The engine
changes to operate with petrol.
Problem:
if the vehicle is left parked for a
long time just after refuelling, the gas level
indicator does not accurately indicate the
same level shown after refuelling when the
vehicle is started up again. This is not due to
a leak in the system, but to a drop in pres-
sure in the gas tank for technical reasons af- ter a cooling phase immediately after refuel-
ling. WARNING
Driving with insufficient fuel reserve could re-
sult in the vehicle breaking down in traffic
and a serious accident.
● If the fuel level is too low then the fuel sup-
ply to the engine can become irregular espe-
cially on slopes.
● If the engine “is choked” or stalls due to
lack of or irregularity of the fuel supply, the
power steering as well as all of the driver as-
sistance systems including braking assis-
tance will stop working.
● Always refuel when there is only one quar-
ter of the fuel tank left to avoid running out of
fuel. CAUTION
● Always pay attention to any lit control
lamps and to the corresponding descriptions and instructions to avoid damage to the vehi-
cle.
● Never run the fuel tank completely dry. An
irregular fuel supply may lead to ignition
faults and unburnt fuel could enter the ex-
haust system. This could damage the catalyt-
ic converter. Note

● Connect the pump filling nozzle to the gas
filler mouth.
● The fuel tank will be full when the pump
c ompr

essor automatically cuts the supply.
● If you 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-
sary, 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-
mable substance. Incorrect handling of the
natural gas can cause accidents serious
burns and other injuries.
● Before refuelling with natural gas, the fill-
ing mouth must be correctly engaged. If you
can smell gas, stop refuelling immediately. 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
● The filling nozzles of natural gas pumps
can differ in the way they are operated. If you
are unacquainted with the pump, it is advisa-
ble that a member of staff of the service sta-
tion performs the refuelling operation. ●
Noises heard when refuelling are normal
and do not indicate the presence of a fault in
the system.
● The vehicle natural gas system is prepared
both for refuelling with a small compressor
(slow refuel) and a large compressor (fast re-
fuel) in natural gas service stations. Bonnet

Introduction WARNING
Incorrectly handling engine oil can cause in-
jury and serious burns.
● Always protect your eyes when handling
engine oil.
● Oil is toxic and must be kept out of the
reach of children.
● Engine oil should only be kept in its origi-
nal packaging; the same goes for used oil un-
til it is disposed of. 146

Checking and refilling levels
●
Never store engine oil in empty food con-
tainers or bottles as other people may acci-
dentally drink it.
● Regular contact with engine oil can be bad
for the skin. If you come into contact with en-
gine oil, wash your skin with soap and water.
● With the engine running, the engine oil
gets extremely hot and can cause severe skin
burns. Always wait until the engine has fully
cooled. For the sake of the environment
Similar to the other service liquids, spilled
engine oil can be bad for the environment.
Collect these liquids in suitable containers
and dispose of them while respecting the en-
vironment. Warning and control lampsFlashesPossible

● The engine must be hot to be able to check
the engine oil level. Stop the engine and wait a few minutes for the oil to drain back into
the sump.
●
Open the bonnet  ››› page 143.
● The engine oil filler neck can be recognised

Check the engine oil level
● Pull out the dipstick and wipe it on a clean
cloth.
● Replace the dipstick, pushing it in as far as
it will go. If the dipstick to measure engine oil
has a mark, when you reintroduce it this
mark should slot into the corresponding
groove located on the upper end of the tube.
● Remove the dipstick again and check the
engine oil level ››› table on page 148.
● After reading the oil level, replace the dip-
stick in the tube completely.
Engine oil topping up ranges
Fig. 107Operations required depending on
the engine oil level:
Area ADo not top up oil
››› .
Area BYou can add oil, but keep the level in this
zone.
Area COil
must be added. After topping up the oil
level should be in area B. Adding oil after checking the level
Only add engine oil in small quantities and in
steps:
●
Unscrew the cap from engine oil filler neck
on the cylinder head ››› Fig. 108 . If you are
not s

ure where the cap is, request help from
a specialist.
● Only refill using approved SEAT engine oil
in small quantities (no more than 0.5 ltr)
››› page 147.
● To av

oid adding too much oil, each time
you add a quantity, wait until the oil has flow-
ed into the crankcase so that it can be meas-
ured with the dipstick.
● Check the oil level before adding any more
oil. Do not top up with too much engine oil
››› .
● When the oil level is in at least the
››› Fig. 107 B zone, insert the dipstick into
the tube fully to avoid engine oil escaping
when the engine is running.
● After topping up the oil, ensure that the
cap is screwed on to the filler neck correctly. WARNING
Oil could catch fire if it comes into contact
with hot engine components. This could lead
to a fire, explosion and severe injuries.
● Always ensure that after topping of oil, the
engine oil filler cap is correctly tightened. 148

Checking and refilling levels
This will avoid engine oil spilling onto hot
engine parts when the engine is running.
CAUTION
● If the engine oil level is above the area Ado not start the engine. Seek specialist assis-
tance. Otherwise catalytic converter and en-
gine damage may occur.
● When refilling or changing service liquids,
ensure that you put the liquids into the right
tank. Making a mistake when refilling could
cause serious malfunctions and damage the
engine! 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. Engine oil consumption
The consumption of engine oil can be differ-
ent from one engine to another and can vary
during the useful life of the engine.
Depending on how you drive and the condi-
tions in which the vehicle is used, oil con-
sumption can be up to 1 ltr./2000 km. In the
case of new vehicles, the consumption can
exceed this figure over 5,000 kilometres. For
this reason the engine oil level must be checked at regular intervals, preferably when
filling the tank and before a journey.
When the engine is working hard, for in-
stance during sustained high-speed motor-
way cruising in summer or when climbing
mountain passes, the oil level should pref-
erably be kept within area
››› Fig. 107 A .
Changing the engine oil The engine oil must be changed regularly ac-
cording to the specifications of the Mainte-
nance Programme.
Due to the problems linked with disposing of
used oil and the need for suitable tools and
special knowledge, always visit a specialised
workshop to have the engine oil and filter
changed. SEAT recommends taking your car
in for technical service.
Detailed information on the service intervals
is shown in the Maintenance Programme.
Engine oil additives make new oil darker after
the engine has been running for a short peri-
od. This is normal and does not mean more
frequent oil changes are required.
WARNING
If, in exceptional circumstances, you must
change the engine oil yourself, please note
the following: ●
Wear eye protection.
● Always wait until the engine has complete-
ly cooled to avoid being burned.
● Always keep your arms horizontal when un-
screwing the oil drainage bolt so that it does
not run down your arms.
● Use a suitable container large enough to
collect all of the used oil in the engine.
● Never collect engine oil in empty food con-
tainers, cans, bottles or other containers as
not all people are able to identify engine oil.
● Oil is toxic and must be kept out of the
reach of children. For the sake of the environment
Before changing the engine oil, find a suita-
ble location or service for proper disposal. For the sake of the environment
Always dispose of engine oil with the utmost
respect for the environment. Never dispose of
used engine oil in places such as a garden,
woods, drains, roads, paths, rivers and drain-
age systems. 149Technical specifications

Engine coolant Introduction WARNING
Engine coolant is toxic!
● Only keep engine coolant in its original
container, tightly shut and in a safe place.
● Never store engine coolant in empty food
containers or bottles as other people may ac-
cidentally drink it.
● Always keep engine coolant out of reach of
children.
● Ensure that the proportion of engine cool-
ant additive corresponds to the lowest out-
side temperature to which the vehicle will be
exposed.
● If the outside temperature is extremely low,
the engine coolant could freeze causing the
vehicle to stop. As this would also cause the
heating to stop working, vehicle occupants
without warm clothing could freeze. For the sake of the environment
Coolants and additives can contaminate the

The engine cooling system is supplied from
the factory with a specially treated mixture of
water and, at least, 40 % of the additive
G 13
(TLVW 774 J). The engine coolant additive is
recognisable by its purple colour. This mix-
ture of water and additive gives the necessa-
ry frost protection down to -25°C (-13 F) and
protects the light alloy parts of the cooling
system against corrosion. It also prevents
scaling and considerably raises the boiling
point of the coolant.
To protect the engine cooling system, the
percentage of additive must always be at
l e

ast 40 %, even in warm climates where an-
ti-freeze protection is not required.
If greater frost protection is required in very
cold climates, the proportion of additive can
be increased. However, the percentage of ad-
ditive should not exceed 60%, as this would
