Ethanol fuel

●

A single refuelling with leaded fuel or

other metal additives entails a permanent
deterioration of the effectiveness of the
catalytic converter.

●

Only use fuel additives that have been

approved by SEAT. The products that con-
tain substances to increase the octane rat-
ing or decrease knocking may contain met-
al additives that damage the engine and
catalytic converter. This type of products
must not be used.

●

Do not use fuels shown in the pump as

containing metals. LRP (

lead replacement

petrol

) fuels contain high concentrations of

metal additives. Risk of engine damage!

●

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.

Note

●

Fuel with an octane rating higher than the

one required by the engine can be used.

●

In countries in which there is no sulphur-

free fuel, it is also allowed to use low sul-
phur content fuel.

Ethanol fuel

Valid for: vehicles with Totalflex engines

You can recognise vehicles with Totalflex en-
gines

by label on the fuel tank lid with the

marking “Petrol/ethanol”.

Vehicles with Totalflex engine can run with
unleaded petrol (95 octane / 91 AKI) accord-
ing to ANP No. 57 and with fuels with any high
percentage of ethanol. The vehicle is refuel-
led in the same way as petrol refuelling.

Also consider that

rol

Note

SEAT recommends filling the tank exclu-
sively with petrol every 10,000 km to de-
crease impurities that using E100 ethanol
fuel might have left in the engine.

Diesel

Valid for: vehicles with diesel engines

Please note the information on the inside of
the fuel tank flap.

The diesel can thicken at very low tempera-
tures, thus affecting the start or operation of
the engine. Ask your service station attendant
if their diesel is suitable for winter use.

Water in the fuel filter

If your vehicle has a diesel engine and is
equipped with a

fuel filter with a water sep-

arator

, the instrument panel may display the

following warning:



Water in the fuel

filter.

If this is the case, take the vehicle to

a specialised workshop so that they can
drain the fuel filter.

CAUTION

●

Never use of FAME (biodiesel that does

not meet the EN590 standard), petrol,
heating oil, other fuels or thinning agents
as they can cause severely damage the
fuel system and the engine.

●

If the wrong fuel has been filled, do not

start the engine under any circumstances.

This motor is only available in some markets.

AdBlue®

Information about AdBlue®

AdBlue® consumption depends on your per-
sonal driving style, the temperature of the
system and the outdoor temperature when
the vehicle is used.

AdBlue® freezes at temperatures of -11 °C
(+13°F). The system has heating elements
that guarantee its operation even at low tem-
peratures.

The AdBlue® tank has a capacity of approx.
18 litres.

When the

range is less than 2400 km

the

instrument cluster screen displays a message
requesting an AdBlue® refill.

If this message is ignored, the yellow warning
lamp will come on when the

remaining

range is less than 1000 km.

Operations prior to refilling

Park the vehicle on a flat surface and turn off
the ignition. If the vehicle is on a slope or on a
curb, the level indicator may not detect the
refill properly.

If an AdBlue® warning message is shown on
the instrument cluster display,

fill with at

least the minimum required amount (ap-
prox. 5 litres)

. Only after adding this amount

will the system detect that AdBlue® has been
added and you will be able to start the en-
gine again. The maximum amount that can
be refilled is 11 litres.

Catalytic converter

To maintain the useful life of the catalytic
converter

●

Only use unleaded petrol with petrol en-

gines.

●

Never run the fuel tank dry.

●

When changing or adding engine oil, do not

exceed the necessary amount

›››

page 342,

Topping up the engine oil

●

Never tow the vehicle to start it, use jump

leads if necessary

›››

page 52

If you should notice misfiring, uneven running
or loss of power when the car is moving, have
the vehicle inspected by a specialised work-
shop. In general, the emissions warning lamp



will light up when any of these symptoms

occur. If this happens, any unburnt fuel can
enter the exhaust system and escape into the

335

Practical tips

atmosphere. The catalytic converter can also
be damaged by overheating.

CAUTION

Never run the fuel tank completely dry be-
cause an irregular fuel supply can cause
ignition faults. This allows unburnt fuel to
enter the exhaust system, which could
cause overheating and damage the cata-
lytic converter.

For the sake of the environment

Even when the emission control system is
working perfectly, there may be a smell of
sulphur from the gases on occasions. This
depends on the sulphur content of the fuel
used. This can quite often be avoided by
changing to another brand of fuel.

Particulate filter

Valid for: vehicles with petrol or diesel particu-

late filters

The particulate filter eliminates most of the
soot from the exhaust gas system. Under nor-
mal driving conditions the filter cleans itself. If
the filter does not clean itself (e.g. if short
journeys are made continuously), it becomes
blocked with soot and the following indica-
tion is displayed to the driver:



Particu-

late filter: cleaned while the vehi-

cle is moving. See Manual.

The partic-

ulate filter needs cleaning (regeneration).

Regeneration of the petrol particulate fil-
ter (only for 2.0l TSI engines)

Requirements for the regeneration journey:

the engine is at operating temperature.

●

Drive at a speed of at least 80 km/h

›››

●

Completely remove your foot from the ac-

celerator pedal for a few seconds to let the
vehicle roll with the gear engaged.

●

Consider the legal speed limits as well as

the recommended gears.

●

Repeat this procedure (accelerate and let

roll) until the control lamp turns off.

This procedure involves an autonomous par-
ticulate filter cleaning process and may take
some time.

If the warning lamp

does not turn off

, go im-

mediately to a specialised workshop to repair
the fault.

Regeneration of the petrol (except the TSI
2.0l engine) and diesel particulate filter

Requirements for the regeneration journey:

the engine is at operating temperature.

●

Drive at a speed of between 50-120 km/h

(31-75 mph). This increases the temperature
and burns the soot in the filter

›››

●

Consider the legal speed limits as well as

the recommended gears.

●

End the regeneration journey once the con-

trol warning lamp has gone out.

If the warning lamp stays on after 30 minutes
of running in regeneration mode, have a spe-
cialised workshop repair the fault

WARNING

Always adjust your speed to suit the weath-
er conditions, roads, braking distance and
traffic if the particulate filter is in its regen-
eration phase. Route recommendations
should never make you disregard each
country's specific traffic regulations.

CAUTION

●

When the exhaust system detects that

the particulate filter is close to saturation,
the self-cleaning function of this system
recommends optimal driving for this func-
tion.

●

Due to the high temperatures caused by

the regeneration of the particulate filter, it
is possible that the radiator fan will acti-
vate after stopping the engine, even it its
operating temperature has not been
reached.

●

Noise, smells and high idle speeds can

occur during regeneration.

●

Always use the correct engine oil and the

correct fuel to make sure the useful life of

336

Checking and refilling levels

the particulate filter is not affected. Also
avoid making short trips all the time.

Engine compartment

Working in the engine compart-
ment

Always be aware of the danger of injury and
scalding as well as the risk of accident or fire
when working in the engine compartment
(e.g. when checking and refilling fluids).

Always observe the warnings listed below
and follow all general safety precautions.

The vehicle's engine compartment is a po-
tentially hazardous area

›››

WARNING

When work is done in the engine compart-
ment, injuries, burns, accidents and even
fires can occur.

●

Turn off the engine, disconnect the igni-

tion e and apply the electronic parking
brake. If the vehicle has a manual gearbox,
place the lever in neutral; if it has an auto-
matic gearbox, place the selector lever in
position P. Wait for the engine to cool down.

●

Never open the bonnet if you see steam

or drips of coolant being released from the
engine compartment. Wait until no steam

or coolant can be seen before opening the
bonnet.

●

Keep children away from the engine

compartment.

●

Never spill liquids used for vehicle opera-

tion on the engine compartment, as these
may catch fire (e.g. the antifreeze in cool-
ant).

●

Avoid causing short-circuits in the elec-

trical system, particularly at the points
where the jump leads are attached

›››

page 52

. The battery could explode.

●

If working inside the engine compart-

ment, remember that, even when the igni-
tion is switched off, the radiator fan may
start up automatically, and therefore there
is a risk of injury.

●

Never cover the engine with additional in-

sulating materials such as a blanket. Risk of
fire!

●

Do not unscrew the cap on the coolant

expansion tank when the engine is hot. The
cooling system is under pressure.

●

Protect face, hands and arms by cover-

ing the cap with a large, thick rag to protect
against escaping coolant and steam.

●

Always make sure you have not left any

objects, such as cleaning cloths or tools, in
the engine compartment.

●

If you have to work underneath the vehi-

cle, you must use suitable stands addition-
ally 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:

–

Never touch the electrical wiring of the
ignition system.

–

Ensure that jewellery, loose clothing
and long hair do not get trapped in ro-
tating engine parts. Danger of death.
Before starting any work remove jewel-
lery, tie back and cover hair, and wear
tight-fitting clothes.

–

Never accelerate with a gear engaged
without taking the necessary precau-
tions. The vehicle could move, even if
the handbrake is applied. Danger of
death.

●

Observe the following additional warn-

ings if work on the fuel system or the elec-
trical system is necessary:

–

Always disconnect the 12-volt vehicle
battery from the on-board network.

–

Do not smoke.

–

Never work near naked flames.

–

Always keep an approved fire extin-
guisher immediately available.

Practical tips

For the sake of the environment

●

Inspect the ground underneath your vehi-

cle regularly so that any leaks are detec-
ted at an early stage. If you find spots of oil
or other fluids in the area where it was
parked, have your vehicle inspected at the
workshop.

●

Service fluids leaks are harmful to the en-

vironment. For this reason you should make
regular checks on the ground underneath
your vehicle. If you find spots of oil or other
fluids, have your vehicle inspected in a
specialised workshop.

SEAT recommends changing the oil at a spe-
cialised workshop. SEAT recommends an Of-
ficial SEAT Service.

SEAT recommends the use of engine oils ap-
proved according to the appropriate VW
standard. Use of engine oils that do not meet
these quality requirements can cause engine
damage.

SEAT recommends the use of Original SEAT
Spare Part engine oils.

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.

CAUTION

Take the following into account if you have
refilled with an engine oil different to those
specified in the aforementioned standards,
or by your SEAT technical service centre:

●

There is no way of completely avoiding

the danger of causing damage to the en-
gine and particulate filter.

●

You can continue driving with the vehicle

if the refill was no more than 0.5 l of engine
oil. Go to a specialised workshop as soon
as possible and request an oil change. Oth-
erwise, there is a danger of engine dam-
age.

gine oil and the filter at a technical service
centre.

●

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.

Cooling system

Coolant specifications

The engine cooling system is supplied from
the factory with a specially treated mixture of
water and at least 40 % of the additive

G12evo

(TL-VW 774 J), purple. This mixture

gives the necessary frost protection down to
-25°C (-13°F) and protects the light alloy
parts of the engine cooling system against
corrosion. It also prevents scaling and con-
siderably raises the boiling point of the cool-
ant.

To protect the cooling system, the percent-
age of additive must always be at least 40 %,
even in warm climates where anti-freeze pro-
tection is not required.

If for weather reasons further protection is
necessary, the proportion of additive may be

increased, but only up to 60 %; otherwise an-
tifreeze protection will diminish and this will
worsen cooling.

When the coolant is topped up, use a mixture
of

distilled water

and at least 40 % of the

additive

G12evo

for optimal protection

against corrosion. Mixing

G12evo

with G13

(TL-VW 774 J), G12 plus-plus (TL-VW 774 G),
G12 plus (TL-VW 774 F), G12 (red) or G11
(green blue) engine coolants decreases pro-
tection again corrosion and should be avoi-
ded.

WARNING

If there is not enough anti-freeze in the
coolant system, the engine may fail lead-
ing to serious damage.

●

Ensure that the percentage of additive is

correct for the lowest expected ambient
temperature in the zone in which the vehi-
cle is to be used.

●

When the outside temperature is very

low, the coolant could freeze and the vehi-
cle would be immobilised.

CAUTION

The original additives should never be
mixed with coolants which are not ap-
proved by SEAT.

●

If the fluid in the expansion tank is not

purple but is, for example, brown, this indi-
cates that the G12evo additive has been

Practical tips

mixed with an inadequate coolant. The
coolant must be changed as soon as possi-
ble if this is the case!

For the sake of the environment

Coolants and additives can contaminate
the environment. If any fluids are spilled,
they should be collected and correctly dis-
posed of, with respect to the environment.

(minimum) mark.

Checking coolant level

–

Park the vehicle in a horizontal position.

–

Switch the ignition off.

–

Read off the coolant level on coolant ex-
pansion tank. When the engine is cold, the
coolant level should be between the marks

›››

. When the engine is hot, it may

be slightly above the upper mark.

Topping up coolant

–

Wait for the engine to cool down.

344

Checking and refilling levels

–

Cover the coolant expansion tank cap with
a cloth and carefully unscrew it to the left

›››

–

Top up the coolant only if there is still cool-
ant in the expansion tank, otherwise you
could

damage the engine

. If there is no

coolant in the expansion tank, do not con-
tinue driving. You should obtain professional
assistance

›››

–

If there is still some coolant in the expansion
tank, top up to the upper mark.

–

Top up with coolant until the level becomes
stable.

–

Screw the cap back on correctly.

If there is a coolant leak, take the vehicle spe-
cialised workshop to have the cooling system
examined.

WARNING

●

The cooling system is under pressure. Do

not unscrew the cap on the coolant expan-
sion tank when the engine is hot: risk of
burns!

●

Store the antifreeze in its original con-

tainer and keep it out of reach of children.

●

If working inside the engine compart-

ment, remember that, even when the igni-
tion is switched off, the radiator fan may
start up automatically, and therefore there
is a risk of injury.

CAUTION

If you run out of coolant in the expansion
tank, park the car in a safe place and do
not continue driving. Obtain technical as-
sistance.

Brake fluid

Check and refill the brake fluid

Fig. 247

Engine compartment: brake fluid res-

ervoir cap.

The brake fluid reservoir is located in the en-
gine compartment

›››

page 339

Checking the brake fluid level

The brake fluid level must be between the



and



markings.

However, if the brake fluid level goes down
noticeably in a short time, or drops below the



mark, there may be a leak in the brake

system. Seek specialist assistance. A warning
light on the instrument panel display monitors
the brake fluid level

›››

page 85

In right-hand drive vehicles the brake fluid
reservoir is on the other side of the engine
compartment.

Changing brake fluid

We recommend that you have the brake fluid
changed by a Technical Service.

WARNING

If the brake fluid level is low or unsuita-
ble/old brake fluid is used, the brake sys-
tem may fail or braking power may be re-
duced.

●

Check the brake system and the brake

fluid level regularly!

●

When the brake fluid is used and brakes

are subjected to extreme braking forces,
bubbles of vapour form in the brake sys-
tem. These bubbles can significantly re-
duce braking power, notably increasing
braking distance, and could result in the to-
tal failure of the brake system.

●

Be sure to always use the correct brake

fluid. Only use brake fluid that expressly
meets the VW 501 14 standard.

345

Practical tips

●

You can buy VW 501 14 standard brake

fluid in a SEAT dealership or a SEAT Official
Service. If none is available, use only high-
quality brake fluid that meets DIN ISO 4925
CLASS 4 standards, or USA Standards
FMVSS 116 DOT 4.

●

The replacement brake fluid must be

new.

●

Brake fluid should be stored in the closed

original container in a safe place out of
reach of children. Risk of poisoning!

CAUTION

Brake fluid should not come into contact
with the vehicle paintwork, as it is abrasive.

For the sake of the environment

Brake fluid is an environmental pollutant.
Collect any spilt service fluids and allow a
professional to dispose of them.

you always add a product to the windscreen
washer fluid.

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 concentrate per 2
parts water); otherwise, a 1:4 proportion of
mixture in the washer fluid tank.

CAUTION

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 wiper system unless you have
warmed the windscreen with the ventila-
tion system. The antifreeze could freeze on
the windscreen and reduce visibility.

346

Checking and refilling levels

CAUTION

Never mix an unsuitable antifreeze or other
similar additives with the windscreen wash-
er water. A greasy layer may be formed on
the windscreen which will impair visibility.

●

Use clean water with a window cleaner

recommended 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 windscreen washer jets.

●

When topping up service fluids, make ab-

solutely certain that you fill the fluids into
the correct reservoirs. Using the wrong flu-
ids could cause serious malfunctions and
engine damage!

●

Lack of window washer fluid causes the

view through the windscreen to be ob-
scured.
