ble.
CAUTION
●
Fuels high percentage of ethanol, e.g.
E30 - E100 button must not be used. The
fuel system would be damaged. Exception:
vehicles with Totalflex engine
›››
.
●
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
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
3
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.

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.
. The indica-
tion that in XXX km it will no longer be possible
to restart the engine will appear on the instru-
ment panel display.
If the yellow indicator lamp is ignored, when
remaining range of 0 km
is displayed, it will
no longer be possible to restart the engine.
The red warning lamp will light up
.
AdBlue® is a registered trademark of the Ger-
man Association of the Automotive Industry
(VDA) and is also known as AUS32 or DEF
(Diesel Exhaust Fluid).

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.
Fill with a refill bottle
Only use AdBlue® that complies with the
ISO 22241-1 standard. Only use original
containers.

Introduction
WARNING
●
Due to the high temperatures reached by
the exhaust gas scrubbing system, you
should not park your vehicle near a surface
that can catch fire easily. Fire hazard!
●
Do not apply wax underneath the vehicle
around the area of the exhaust system: Fire
hazard!

Note
While the control lamps
,
,
or
are
on, there might be faults in the engine, fuel
consumption may go up and the engine
might lose power.
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
.
●
Never tow the vehicle to start it, use jump
leads if necessary
.
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
3
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
›››
. 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.

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.

Depending on how you drive and the condi-
tions in which the vehicle is used, oil con-
sumption can be up to 0.5 l/1000 km. Oil
consumption is likely to be higher for the first
5,000 km. For this reason the engine oil level
must be checked at regular intervals, prefera-
bly when filling the tank and before a journey.
WARNING
Any work carried out in the engine com-
partment or on the engine must be carried
out cautiously.
●
When working in the engine compart-
ment, always observe the safety warnings

●
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 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 addi-
tives would not be covered by the factory
warranty.
For the sake of the environment
●
We recommend that you change the en-
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

(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

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.

.
Top up coolant when the level is below the
(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
.
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
.
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.

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.
Windscreen washer reservoir
Checking the level of the window
washer tank and refilling it
Fig. 248
In the engine compartment: blue cap
of the windscreen washer tank.
The window washer tank is in the engine
compartment
.
Check the water level in the windscreen
washer reservoir regularly and top up as re-
quired.
The window washer tank contains liquid de-
tergent for the windscreen and rear window.
●
Open the bonnet
.
●
The window washer tank is marked with the
symbol on the cap.
●
Check there is enough windscreen water in
the reservoir.
Plain water is not enough to clean the wind-
screen and headlights. We recommend that
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.
The capacity of the window washer tank can
be found in

.
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.
12-volt battery
General information
The battery is located in the engine compart-
ment
›››
(PHEV hybrid vehicles)
›››
and is
practically
maintenance free
. It is checked
as part of the Inspection Service. Neverthe-
less, check the terminals are clean and have
the correct tightening torque, especially in
summer and winter.
All work on batteries requires specialist
knowledge. Please refer to a SEAT Official
Service or a workshop specialising in batter-
ies: risk of burns or exploding battery!
The battery must not be opened.
Never try
to change the fluid level of the battery. Oth-
erwise explosive gas is released from the bat-
tery that could cause an explosion.
Battery warning indications
Wear eye protection.
Battery acid is extremely corrosive. Wear pro-
tective gloves and eye protection. Rinse any
splashes of electrolyte with plenty of water.
Fires, sparks, open flames and smoking are
prohibited.
The battery should only be charged in a well-
ventilated zone. Risk of explosion!
Keep children away from acid and batteries!
Always follow the instruction manual.
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. These functions will require resetting
after the battery is reconnected.
When disconnecting the battery from the ve-
hicle on-board network, disconnect first the
negative cable and then the positive cable.
Deactivate the anti-theft alarm before you
disconnect the battery. Otherwise the alarm
will be triggered.
If the vehicle is not used for long periods
The vehicle has a system for monitoring the
current consumption when the engine is left
unused for long periods of time
.
Some functions, such as the interior lights, or
the remote door opening, may be temporarily
disabled to prevent the battery from running
flat. These functions will come back on as
soon as the ignition is switched on and the
engine started.
Winter conditions
During the winter, the starting power may be
reduced, and if necessary, the battery should
be charged
.
WARNING
Any work to be done on the 12-volt vehicle
battery or electrical system can cause in-
juries, burns, accidents and fires:
