Introduction

Take into account country-specific regulations
about driving with a trailer and the use of a
towing bracket.
The vehicle has been developed primarily for
carrying people, although it can also be used
to tow a trailer if fitted with the corresponding
technical equipment. This additional load has
an effect on the useful life, fuel consumption
and vehicle performance and in some cases
can reduce the service intervals.
Driving with a trailer requires more force from
the vehicle, and thus more concentration from
the driver.
In winter, winter tyres should be fitted on both
the vehicle 

and

 the trailer.

Maximum vertical load technically permit-
ted on the coupling device

The 

maximum

 vertical load technically permit-

ted from the trailer draw bar on the towing
bracket's tow ball is 

100 kg

.

Vehicles with the Start-Stop system

If the vehicle has a factory-fitted towing
bracket or one that is retrofitted by SEAT, the
Start-Stop system operates as normal. No spe-
cial characteristics need to be taken into ac-
count.

If the system does not recognise the trailer or
the trailer bracket has not been retrofitted by
SEAT, the Start-Stop system must be discon-
nected by pressing the corresponding button
in the lower part of the centre console before
driving with the trailer, and it should remain off
for the rest of the journey 

››› 

.

Vehicles with driving profile selection

If you are going to be towing a trailer, the use of
the 

Eco

 driving profile is not recommended. You

are advised to select another of the available
driving profiles before beginning to drive with a
trailer.

Trailer weight/drawbar load

Never exceed the authorised trailer weight. If
you do not load the trailer up to the maximum
permitted trailer weight, you can then climb
correspondingly steeper slopes.
The maximum trailer weights listed are only ap-
plicable for 

altitudes

 up to 1000 m above sea

level. Since higher altitude decreases engine
performance and the ability to climb slopes, the
tow load decreases proportionally. The weight
of the vehicle and trailer combination must be
reduced by 10% for every 1000 m of altitude.
When possible, operate the trailer with the max-
imum 

authorised drawbar load

 on the ball

joint of the towing bracket, but 

do not exceed

the specified limit.

WARNING

Never use the trailer to transport people,
since it would put their life in danger and is
also prohibited.

WARNING

Undue use of the towing bracket may cause
injury and accidents.

Only use the towing bracket if it is in a per-

fect state of repair and is properly secured.

Never modify or repair the towing bracket

in any way.

In order to reduce the danger of injury in

the event of rear-end collisions and to avoid
injury to pedestrians and cyclists when park-
ing the vehicle, cover or remove the tow hook
when you are not using a trailer.

According to EU regulation 2021_535 it is

not permitted to install a towing device that
completely or partially covers the rear num-
ber plate.

Never fit a towing bracket “with weight dis-

tribution” or “load compensation”. The vehi-
cle has not been designed for this type of
towing bracket. The towing bracket could fail
and the trailer could be released from the
vehicle.

WARNING

Driving with a trailer and transporting heavy
or large objects can affect driving properties
and even cause an accident.

Always secure the load properly using

belts or straps that are suitable and in good
condition.

Adapt your speed and driving style at all

times to suit visibility, weather, road and
traffic conditions.

Trailers with a high centre of gravity are

more likely to overturn than those with a low
one.

Avoid sudden braking and manoeuvres.

Take great care when overtaking.

Reduce speed immediately if you notice

that the trailer is swaying, however slightly.

Never drive at more than 80 km/h (50 mph)

when towing a trailer (or at more than
100 km/h (60 mph) in exceptional circum-
stances). This also applies in countries where
driving at higher speeds is permitted. Take
into account the speed limit for vehicles with
trailers in the corresponding country, as it
could be less than the speed limit for vehi-
cles without a trailer.

Never attempt to “straighten” the towing

vehicle and trailer while accelerating.

WARNING

If the towing bracket has been retrofitted by
a non-SEAT workshop, the Start-Stop system
must be disconnected manually whenever
driving with a trailer. Otherwise the brake
system could be damaged and could conse-
quently cause a serious accident or injury.

 Always disconnect the Start-Stop system

manually when using a towing bracket that
has not been fitted by a SEAT workshop.

Note

 Before hitching or unhitching a trailer,

always deactivate the anti-theft alarm 

››› 

page 91

. Otherwise, the tilt sensor could

cause the alarm to go off.

Do not drive with a trailer for the engine's

first 1000 km 

››› 

page 151

.

Some retrofitted towing brackets cover the

rear towing eye. In these cases, the towing
eye should not be used for tow-starting or
for towing other vehicles. For this reason, if
the vehicle has been retrofitted with a towing
bracket, always keep the tow hook in the ve-
hicle when you remove it.

Technical requirements

Vehicles that are

 factory

-equipped with a tow-

ing bracket fulfil all the technical and legal re-
quirements for driving with a trailer.

If the 

vehicle is retrofitted with a tow bracket

,

only a bracket that is authorised for the max-
imum authorised load of the trailer that is to
be towed may be fitted. The towing bracket
must be suitable for the vehicle and the trailer
and must be properly secured to the vehicle's
chassis. Only use a towing bracket that has
been authorised by SEAT for this vehicle. Al-
ways check and take into account the towing
bracket manufacturer's instructions.

Towing bracket fitted on the bumper

Never fit a towing bracket to the bumper or to
the area where the bumper is mounted. The
towing bracket should not impair the bumper's
function. Do not make modifications or repairs
to the exhaust system or the brake system.
Make regular checks to ensure that the towing
bracket is secure.

Engine cooling system

Driving with a trailer increases the load on the
engine and cooling system. The cooling system
should have sufficient coolant and be prepared
for the additional effort involved in driving with
a trailer.

Trailer brakes

If the trailer has its own brake system, please
take the relevant legal requirements into ac-
count. Never connect the trailer's brake system
to the vehicle's brake system.

Never connect the trailer's rear lights directly
to the vehicle's electric system. If you are not
sure that the trailer's electrical connection is
correct, have it checked by a specialised work-
shop. SEAT recommends visiting a SEAT dealer-
ship for this.

Exterior mirrors

If you cannot see the area behind the trailer
with the exterior mirrors of the towing vehicle,
additional mirrors will have to be installed in
accordance with the regulations of the country
in question. The exterior mirrors should be ad-
justed before you start driving and must provide
a sufficient field of vision at the rear.

NOTICE

 If the rear lights of the trailer are not

correctly connected, the vehicle's electronic
system may be damaged.

If the trailer absorbs excessive electric cur-

rent, the vehicle's electronic system may be
damaged.

Never connect the trailer's electric system

directly to the electrical connections of the
tail lights or any other power sources. Only
use the connections intended for providing
electric current to the trailer.

Power socket for trailer

The vehicle is fitted with a 13-pole power socket
for the connection between the trailer and the
vehicle. With the engine running, electrical devi-
ces on the trailer receive power from the elec-
trical connection (pin 9 and pin 10 of the trailer
power socket).
If the system detects that a trailer has been
connected, the consumers on the trailer will re-
ceive electricity through this connection (pins 9
and 10). Pin 9 has a permanent live. This pow-
ers, for example, the trailer's interior lighting.
Electrical devices such as a fridge in a caravan

only

 receive electrical power if the engine is

running (through pin 10).
To avoid overloading the electrical system, you
cannot connect the ground wires of pin 3, pin 11
or pin 13.
If the trailer has a 

7-contact connector

, you

will need to use an adapter cable. In this case
the function corresponding to pin 10 will not be
available.

Tow cable

The tow rope must always be securely fixed to
the towing vehicle and loose enough so that the
vehicle can handle turns smoothly. However,
make sure that the cable does not rub on the
ground while driving.

Trailer tail lights

Always check the trailer's rear lights to ensure
they are working correctly and that they com-
ply with the relevant safety regulations. Make
sure that the maximum permissible power that
can be absorbed by the trailer is not exceeded 

››› 

page 300

.

Include in the anti-theft alarm

The trailer is included in the anti-theft system if
the following conditions are met:

 If the vehicle is factory-equipped with an

anti-theft alarm.

If the vehicle is factory-equipped with a tow

bracket.

If the trailer is electrically connected to the

towing vehicle through the trailer power socket.

If the electrical systems of the vehicle and

trailer are in perfect condition and have no
faults or damage.

If the vehicle is locked with the key and the

anti-theft alarm is activated.

When the vehicle is locked, the alarm is trig-
gered if the electrical connection with the
trailer is cut off.
Before hitching or unhitching a trailer, always
turn off the anti-theft alarm. Otherwise, the tilt
sensor could cause the alarm to go off.

Trailers with LED tail lights

For technical reasons, trailers fitted with LED
rear lights cannot be connected to the anti-
theft alarm system.
When the vehicle is locked, the alarm does not
go off when the electrical connection with the
trailer is cut if it has rear lights with light-emit-
ting diodes.

If the 

Eco

 driving profile was selected when

hitching the trailer, this will automatically switch
to the

Normal

 profile. If the system cannot de-

tect the attached trailer or if the towing bracket
has been retrofitted by an auto repair shop
other than SEAT, you must manually select the

Normal

 profile before you start driving with a

trailer attached. To reconnect the 

Eco

 profile

once the trailer has been unhitched, switch the
ignition off and back on once.

WARNING

If the cables are improperly or incorrectly
connected, it may lead to an excessive
amount of current supplied to the trailer,
which can cause abnormalities in the entire
vehicle electronic system, as well as acci-
dents and serious injuries.

 Ensure that any repairs that need to be

carried out on the electrical system are car-
ried out by a specialised workshop.

Never connect the trailer's electric system

directly to the electrical connections of the
tail lights or any other power sources.

WARNING

Contact between the pins of the trailer
power socket can cause short circuits, over-
loading of the electrical system or failure of
the lighting system, and consequently can
cause accidents and serious injuries.

 Never connect the pins of the trailer power

socket to each other.

Make sure any work on bent pins is carried

out by a specialised workshop.

NOTICE

Do not leave the trailer connected to the ve-
hicle when parked; place it on its support
wheel or its supports. If the vehicle rises or
falls due, for example, to a variation of the
load or a burst tyre, increased pressure will
be placed on the towing bracket and the
trailer, and both the vehicle and the trailer
can be damaged.

Note

In case of anomalies in the electrical sys-

tems of the vehicle or trailer, as well as in the
anti-theft alarm system, have them inspec-
ted by a specialised workshop.

If the trailer accessories consume energy

through the power socket to the trailer and
the engine is turned off, the battery will dis-
charge.

If the vehicle battery is running low, the

electrical connection with the trailer will be
automatically cut.

Trailer loading

Technically permissible maximum trailer
weight and vertical load on the coupling de-
vice

The technically permissible maximum trailer
weight is the weight that the vehicle can tow 

››› 

. The vertical load on the coupling is ex-

erted vertically from above on the hook of the
towing bracket.
The information on the maximum trailer weight
and vertical load on the coupling device con-
tained in the type plate of the towing bracket
are experimental values only. The correct fig-
ures for your specific model, which may be
lower than these figures, are given in the vehicle
documentation. The information in the vehicle
documentation takes precedence at all times.
To promote safety while driving, SEAT recom-
mends making the most of the maximum ver-
tical load technically permissible on the cou-
pling device 

››› 

page 299

. An insufficient ver-

tical load has a negative influence on the be-
haviour of both the vehicle and trailer.
The vertical load increases the weight on the
rear axle, reducing the vehicle's carrying ca-
pacity.

CarManuals2.com

304

Storing objects

Gross combination weight of the towing ve-
hicle and trailer

The gross combination weight is the actual
weight of the loaded vehicle plus the actual
weight of the loaded trailer.
In some countries trailers are classified into
distinct categories. SEAT recommends obtain-
ing information from a specialised workshop re-
garding which type of trailer is most suitable for
your vehicle.

Trailer loading

The weight of the towing vehicle and trailer
must be balanced. In order to do this, the load
must be as close as possible to the maximum
vertical load technically permissible on the
coupling point, and it must be evenly distributed
between the back and front of the trailer:

 Distribute loads in the trailer so that heavy

objects are as near to the axle as possible or
above it.

Secure the trailer load properly.

Tyre pressure

Set the tyre pressure of the trailer tyres in ac-
cordance with the trailer manufacturer's rec-
ommendations.
When towing a trailer, inflate the tyres of the
towing vehicle with the maximum allowable
pressure 

››› 

page 352

.

WARNING

If the maximum permissible axle weight, the
maximum load technically permissible on the
coupling point, the maximum authorised ve-
hicle weight or the gross combination weight
of the towing vehicle and trailer are excee-
ded, accidents and serious injuries may oc-
cur.

Never exceed the indicated values.

The actual weight on the front and rear

axles must never exceed the maximum per-
missible axle weight. The weight on the front
and rear axles must never exceed the maxi-
mum permissible weight.

WARNING

A shift in weight could jeopardize the stability
and security of the towing vehicle and trailer,
which could lead to accidents and serious
injuries.

Always load the trailer correctly.

Always secure the load properly using

belts or straps that are suitable and in good
condition.

Driving with a trailer

Adjusting the headlights

The front part of the vehicle may be raised
when the trailer is connected and the light may
dazzle the rest of the traffic.

Specific features of driving with a trailer

 If your trailer has an 

overrun brake

, brake

gently at first

 and then rapidly. This will prevent

the jerking that can be caused by the locking of
trailer wheels.

Due to the gross combination weight of the

towing vehicle and trailer, the braking distance
increases.

When going down a slope, engage a lower

gear (with a manual gearbox, or use the auto-
matic gearbox's tiptronic mode) to use engine
braking. Otherwise, the brake system could
overheat and even fail.

The trailer weight, as well as the gross combi-

nation weight of the towing vehicle and trailer,
change the centre of gravity and the properties
of the vehicle.

If the towing vehicle is empty and the trailer

is loaded, then the load distribution is incorrect.
Under these conditions, drive slowly and with
extra caution.

Hill starts with a trailer

Depending on the slope of the hill and the
combination weight of the towing vehicle and
trailer, the vehicle might start rolling backwards
slightly when you first start up.
For hill starts with a trailer hitched:

 Press and hold the brake pedal.

WARNING

If a trailer is pulled incorrectly, this may lead
to loss of control of the vehicle and serious
injury.

Driving with a trailer and transporting

heavy or large objects will change the vehi-
cle handling and braking distances.

Always drive cautiously and carefully.

Brake earlier than usual.

Adapt your speed and driving style at all

times to suit visibility, weather, road and
traffic conditions. Slow down, especially
when driving down hills or slopes.

Accelerate with particular care and cau-

tion. Avoid sudden braking and manoeuvres.

Take great care when overtaking. Reduce

speed immediately if you notice that the
trailer is swaying, however slightly.

Never attempt to “straighten” the towing

vehicle and trailer while accelerating.

Take into account the speed limit for vehi-

cles with a trailer, as it could be lower than
for vehicles without a trailer.

Stabilisation of the towing vehicle
and trailer combination

The stabilisation of the vehicle and trailer com-
bination is an additional function of the elec-
tronic stability control (ESC).
If the system detects that the trailer is weaving,
it intervenes to reduce the swaying of the trailer.

Vehicle and trailer combination stabilisation
requirements

 The vehicle is factory-equipped with a tow-

ing bracket or has been retro-fitted with a com-
patible towing bracket.

The ESC and TCS are active. The control

lamp   or   is not lit up on the instrument clus-
ter.

The trailer is connected to the towing vehicle

through the trailer power socket.

The vehicle is travelling at over 60 km/h (ap-

prox. 37 mph).

The maximum vertical load technically per-

missible is not being exceeded on the coupling
device.

The trailer has a rigid draw bar.

If the trailer has brakes, it must be equipped

with a mechanical overrun brake.

WARNING

The enhanced safety provided by the elec-
tric stability control of the vehicle and trailer
should not lead you to take any risks that
could compromise your safety.

Adapt your speed and driving style at all

times to suit visibility, weather, road and
traffic conditions.

Accelerate with caution when the road is

slippery.

When adjusting any settings, stop acceler-

ating.

WARNING

The electric stability control for the vehicle
and trailer may not correctly detect all driv-
ing conditions.

 When the ESC is switched off, the stabili-

sation of the towing vehicle and trailer is also
switched off.

The stability system does not always de-

tect light trailers, so it may not stabilise
these correctly.

CarManuals2.com

306

Storing objects

When driving on surfaces with poor grip,

the trailer can even interfere with the stabil-
ity system.

Trailers with a high centre of gravity can tip

over without having previously weaved.

If a trailer is not attached, but a connector

is plugged into the power socket (e.g. instal-
lation of a bicycle rack with lights), repea-
ted automatic braking may occur in extreme
driving conditions.

If the tow hook is not attached properly, do

not use it. Instead, go to a specialised work-
shop and have the towing bracket checked.

If you detect any fault in the electrical sys-

tem or in the towing bracket, contact a speci-
alised workshop and ask them to check it.

If the ball has a diameter of less than

49 mm at any one point, do not use the tow-
ing bracket under any circumstances.

NOTICE

If you clean the vehicle with high-pressure
or steam devices, do not point the jet di-
rectly towards the retractable tow hook or
the trailer power socket, as this may damage
the joints or remove the grease necessary for
lubrication.

Note

At extremely low temperatures, the tow hook
may be impossible to operate. In this case,
place the vehicle in a warmer location (for
example, a garage).

Installing a rear carrier system or a
bicycle rack on the trailer hitch

Fig. 211 

Recommended weight distribution on

the rear support system.

Examples of rear carrier systems are bicycle
racks or multi-purpose boxes that are installed
on the trailer hitch.
Only use rear carrier systems that have been
specified by the respective manufacturer for
the vehicle model, model year and version of
the vehicle in question 

››› 

.

SEAT recommends the use of genuine SEAT
spare parts and accessories, which can be pur-
chased from the brand’s dealers. Install the rear
carrier system according to the manufacturer’s
installation instructions.
The load capacity results from the weight of the
rear carrier system and the weight of the load
carried on it.

The recommended maximum load capacity of
the rear carrier system installed on the trailer
hitch may be different from the maximum verti-
cal load on the specific vehicle coupling.
However, it is not permitted to exceed the max-
imum permitted vertical load on the tow hitch
(which depends on the model).
The load capacity is reduced due to the lever
effect that occurs the further the carrier system
is from the ball head.
Place heavy objects as close as possible to the
trailer hitch

WARNING

The incorrect use of a rear carrier system in-
stalled on the tow hook can cause accidents
and injury.

Make sure that the carrier system is suita-

ble for your vehicle.

Read and observe the installation instruc-

tions of the rear carrier system manufacturer.

Never attach a rear carrier system below

the ball head of the trailer hitch. The system
could slip due to the shape of the hitch.

Note

Before setting off, SEAT recommends remov-
ing, to the extent possible, all accessories
from the load attached to the carrier system.
Examples of these accessories are baskets
and panniers, child seats or batteries. This
improves the aerodynamics and centre of
gravity of the rear carrier system.

technically permissible maximum vertical load
on the coupling device.

WARNING

If the cables are improperly or incorrectly
connected, this may lead to malfunctions in
the entire vehicle electronic system, as well
as to accidents and serious injuries.

Never connect the trailer's electric sys-

tem to the electrical connections of the tail
lights or any other unsuitable power sources.
Only use suitable connectors to connect the
trailer.

The towing bracket should be retrofitted

only at a specialised workshop.

WARNING

If the towing bracket is badly fitted or unsuit-
able, the trailer may separate from the ve-
hicle while driving. This could cause serious
accidents and fatal injuries.

Note

According to regulation EU2021_535 it is

not permitted to install a towing device that
cannot be removed or retracted.

Only use towing brackets that have been

approved by SEAT for the model in question.

In some versions, the fitting of a conven-

tional towing hook solution is not recommen-
ded. Please consult your Technical Service.

Refuelling

Safety warnings regarding fuel han-
dling

WARNING

Fuel is highly flammable and can cause seri-
ous burns and other injuries.

When refuelling, turn off the engine and

turn off the ignition for safety reasons.

The fuel system of PHEV models is pressur-

ized to prevent petrol vapours from escaping
into the atmosphere.

Do not smoke when filling the fuel tank or

a canister. Naked flames are forbidden in the
vicinity due to the risk of explosion.

Observe legislation governing the use,

storage and carrying of a spare fuel canister
in the vehicle.

For safety reasons we do not recommend

carrying a spare fuel canister in the vehicle.
In an accident the canister could be dam-
aged and could leak.

If, in exceptional circumstances, you have

to carry a spare fuel canister, please observe
the following points:

Never fill fuel into the spare fuel canister

if it is inside or on top of the vehicle. This
could cause an explosion. Always place
the canister on the ground to fill it.

Insert the filling nozzle as far as possible

into the spare fuel canister.

If the spare fuel canister is made of

metal, the filling nozzle must be in contact
with the canister during filling. This helps
prevent an electrostatic charge building
up.

Never spill fuel in the vehicle or in the

luggage compartment. Fuel vapour is ex-
plosive. Risk of fatal accident!

NOTICE

If any fuel is spilt onto the vehicle, it should

be removed immediately. It could otherwise
damage the paintwork.

 Never run the tank completely dry. The

catalytic converter can be damaged.

When filling the fuel tank after having run

it completely dry on a vehicle with a diesel
engine, the ignition must be switched on for
at least 30 seconds before starting the en-
gine. When you then start the engine it may
take longer than normal (up to one minute) to
start firing.

For the sake of the environment

Do not overfill the fuel tank, it may cause the
fuel to overflow if it becomes warm.

Note

There is no emergency mechanism for the
manual release of the fuel tank flap. If nec-
essary, request assistance from specialised
personnel.

Note

Diesel vehicles are fitted with a protective
device that prevents the insertion of the
wrong fuel hose

1)

. It is only possible to refuel

with Diesel nozzles.

If the pump nozzle is worn, damaged, or if

it is very small, it is possible that it will not
be able to open the protective device. Before
trying to insert the pump nozzle by turning
it, try a different pump or request specialist
help.

If you fill the tank from a reserve fuel canis-

ter, the protective device will not open. One
way to resolve this is to pour the fuel in very
slowly.

Identification of fuels

1)

Fig. 216 

Identification of fuels according to

European Union (EU) Directive 2014/94/

Fuels are identified by different symbols on
the pump and on your vehicle's tank flap. The
identification serves to prevent confusion when
choosing the fuel.

Petrol

 with ethanol (“E” stands for 

E

thanol).

The number indicates the percentage of
ethanol in the petrol. “E5” means, for exam-
ple, an ethanol ratio of 5% max.

Diesel

 according to EN590 standard. The

number indicates the maximum percent-
age of Biodiesel in the fuel. “B7” means a
maximum of 7% Biodiesel.

Type of petrol

The correct grade of petrol is listed inside the
fuel tank flap.
The vehicle is equipped with a catalytic con-
verter and must only be run on 

unleaded pet-

rol

. The petrol must comply with the standard

EN 228 and be 

sulphur-free

. Fuels with a 10%

ethanol ratio can be refuelled (E10)

2)

. The types

of petrol are differentiated by using the 

octane

numbers (RON)

 or via the 

anti-knock index

(AKI)

.

Super unleaded petrol 95 octane petrol or
normal 91 octane petrol at least

We recommend refuelling with super 95 octane
petrol (91 AKI). If not available, normal 91 oc-
tane petrol (87 AKI) (with a slight power loss)
may be used.

Super unleaded petrol, 95 octanes at least

You should use super 95 octane petrol (91 AKI)
at least.
If super petrol is not available, if necessary, use
normal 91 octane petrol (87 AKI). In this case
only use moderate engine speeds and a light
throttle. Refuel with super as soon as possible.

Unleaded super plus 98 octane petrol or su-
per 95 octane petrol at least

We recommend refuelling with super plus 98
octane petrol (93 AKI). If not available: super 95
octane petrol (91 AKI) (with a slight power loss).
If super petrol is not available, if necessary, use
normal 91 octane petrol (87 AKI). In this case
only use moderate engine speeds and a light
throttle. Refuel with super as soon as possible.

NOTICE

 Fuels with a high percentage of ethanol,

e.g. E30 - E100 button must not be used. The
fuel system would be damaged.

A single refuelling with leaded fuel or other

metal additives entails a permanent deterio-
ration of the effectiveness of the catalytic
converter.

Only use fuel additives that have been ap-

proved by SEAT. The products that contain
substances to increase the octane rating or

decrease knocking may contain metal addi-
tives 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 sulphur
content fuel.

Ethanol fuel

 Valid for: vehicles with Totalflex engines

You can recognise vehicles with Totalflex en-
gines

1)

 by label on the fuel tank lid with the

marking “Petrol/ethanol”.

Vehicles with Totalflex engine can run with un-
leaded petrol (95 octane / 91 AKI) according
to ANP No. 57 and with fuels with any high per-
centage of ethanol. The vehicle is refuelled in
the same way as petrol refuelling.

Also consider that 

››› 

page 312, 

Type of petrol

.

Note

SEAT recommends filling the tank exclusively
with petrol every 10,000 km to decrease im-
purities 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

2)

If your vehicle has a diesel engine and is equip-
ped with a 

fuel filter with a water separator

,

the instrument panel may display the following
warning:

 Water in the fuel filter.

If this is the case, take the vehicle to a special-
ised workshop so that they can drain the fuel
filter.

NOTICE

 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.
Risk of damaging the fuel system and the en-
gine! Seek professional assistance.

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 

››› 

page 320

.

If you should notice misfiring, uneven running or
loss of power when the car is moving, have the
vehicle inspected by a specialised workshop.
In general, the emissions warning lamp  will
light up when any of these symptoms occur. If
this happens, any unburnt fuel can enter the ex-
haust system and escape into the atmosphere.
The catalytic converter can also be damaged
by overheating.

NOTICE

Never run the fuel tank completely dry be-
cause an irregular fuel supply can cause ig-
nition faults. This allows unburnt fuel to enter
the exhaust system, which could cause over-
heating and damage the catalytic 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 indication is
displayed to the driver:

 Particulate filter: cleaned

while the vehicle is moving. See
Manual.

The particulate filter needs cleaning (regenera-
tion).

Regeneration of the petrol and diesel partic-
ulate filter

1)

Requirements for the regeneration journey:

 the

engine is at operating temperature.

Drive at a speed of between 50120 km/h

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

››› 

page 317

.

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 speci-
alised workshop repair the fault.

Regeneration of the particulate filter (only
for 2.0l and 2.5l TSI engines)

Engine management and emissions control system

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 imme-

diately to a specialised workshop to repair the
fault.

WARNING

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

Note

If during the particulate filter regeneration
process you also get a fuel reserve warning

, the process may be interrupted. Refuel

and continue with the particulate filter re-
generation process.

NOTICE

 When the exhaust system detects that the

particulate filter is close to saturation, the
self-cleaning function of this system recom-
mends optimal driving for this function.

Due to the high temperatures caused by

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

Noise, smells and high idle speeds can oc-

cur during regeneration.

Always use the correct engine oil and the

correct fuel to make sure the useful life of the
particulate filter is not affected. Also avoid
making short trips all the time.

engine is running.

Removing the jump leads

Before you remove the jump leads, switch
off the dipped beam headlights if they are
switched on.
Turn on the heater blower and heated rear
window in the vehicle with the flat battery.
This helps minimise voltage peaks which
are generated when the leads are discon-
nected.
When the engine is running, disconnect the
leads in reverse order to the details given
above.

If the engine fails to start after about 10 sec-
onds, switch off the starter and try again after
about 1 minute.

WARNING

Please note the safety warnings refer-

ring to working in the engine compartment 

››› 

page 331

.

The battery providing assistance must

have the same voltage as the flat battery
(12V) and approximately the same capacity
(see imprint on battery). Failure to comply
could result in an explosion.

Never use jump leads when one of the bat-

teries is frozen. Danger of explosion! Even
after the battery has thawed, battery acid
could leak and cause chemical burns. If a
battery freezes, it should be replaced.

Keep sparks, flames and lighted cigarettes

away from batteries, danger of explosion.
Failure to comply could result in an explo-
sion.

Observe the instructions provided by the

manufacturer of the jump leads.

Do not connect the negative cable from

the other vehicle directly to the negative ter-
minal of the flat battery. The gas emitted
from the battery could be ignited by sparks.
Danger of explosion.

Never attach the negative cable to fuel

system components or the brake lines in the
other vehicle.

The non-insulated parts of the battery

clamps must not be allowed to touch. The
jump lead attached to the positive battery
terminal must not touch metal parts of the
vehicle, this can cause a short circuit.

CarManuals2.com

322

Miscellaneous situations

Position the leads in such a way that they

cannot come into contact with any moving
parts in the engine compartment.

Do not lean on the batteries. This could re-

sult in chemical burns.

Take into account the instruction manual of

the jump lead manufacturer and the instruc-
tion manual of the other vehicle.

NOTICE

Immediately go to a specialist workshop and
have the 12 volt battery checked.

Towing the vehicle

Introduction

It takes practice to tow a vehicle, especially
when using a tow cable. Both drivers should be
well informed of the special features of towing.
Inexperienced drivers should refrain from tow-
ing.
During towing, make sure at all times that no
inadmissible traction forces or jolts are gener-
ated. On roads without a firm surface there is
always the danger of overloading the attach-
ment parts.
Take into account the legal provisions regarding
tow starting and towing.

Tow start

Tow starting means starting a vehicle's engine
while another puts it in motion by pulling it.
The vehicle can be towed with a tow bar or
cable

Towing

Towing means a vehicle pulling another vehicle
that is not in a condition to run.
The vehicle can be towed with a tow bar or
cable.

The maximum permitted speed is 50 km/h

(30 mph).

The maximum permitted distance is 50 km

(30 miles).

Tow cable and tow bar

It is safer for the vehicle to be towed using a tow
bar, avoiding damage to the vehicle. The tow
cable should only be used if a tow bar is not
available.
A tow rope should be slightly elastic to avoid
damage to both vehicles. It is advisable to use
a tow rope made of synthetic fibre or similarly
elastic material.

Tow with a tow truck

If a breakdown lorry is used, vehicles with au-
tomatic transmission are only allowed to be
towed with the front wheels suspended.

Towing vehicles with four-wheel drive
(4Drive)

Four-wheel drive vehicles (4Drive) can be
towed using a tow bar or tow rope. If the vehicle
is towed with the front or rear axle suspended,
the engine must be switched off, otherwise the
transmission may be damaged.

WARNING

During the towing of a vehicle, the driving
behaviour and braking capacity change con-
siderably.

WARNING

Never allow the vehicle to be towed if it has
no power.

When towing, never remove the key from

the ignition or disconnect the ignition with
the ignition and start button. Otherwise, the
electronic lock of the steering column could
suddenly get blocked and it would be impos-
sible to steer the vehicle. This could cause an
accident, serious injury and loss of control of
the vehicle.

If the vehicle runs out of power during tow-

ing, stop the process immediately and seek
the assistance of specialised personnel.

CarManuals2.com

Miscellaneous situations

323

Towing the vehicle

NOTICE

Towing the vehicle with a tow cable or a tow
bar can cause damage to the vehicle.

If the vehicle is towed with a tow cable or

tow bar, special care must be taken.

If possible, have the vehicle transported on

a tow truck.

NOTICE

If the vehicle is pushed by hand, the tail light
units, the side spoilers of the rear window
and large sheet metal surfaces may be dam-
aged. In addition, the rear spoiler could be
detached.

If the vehicle is pushed by hand, the tail

light units, the side spoilers of the rear win-
dow, large sheet metal surfaces or the rear
spoiler.

NOTICE

Removing and attaching the cover and the
towing eye may cause damage to the vehi-
cle, for example, on the paintwork.

To avoid damaging the vehicle, remove and

replace the cover and the towing eye care-
fully.

NOTICE

Using a towing eye that is not suitable for the
vehicle can damage it.

When towing, always use the vehicle’s tow-

ing eye, which forms part of the on-board
tools, or an appropriate eye for towing.

Instructions for tow-starting and
towing

During towing, the change of direction can be
signalled on the towed vehicle even when the
hazard warning lights are on. To do so, at the
same time, the turn signal lever must be oper-
ated with ignition switched on. During this time
the hazard warning lights remain disconnected.
When the turn signal lever is returned to the
rest position, the hazard warning lights will be
automatically reactivated.

Cases where tow starting and towing the ve-
hicle are not permitted

Do not allow the vehicle to be towed in the
following situations:

The vehicle’s gearbox is damaged or has no

lubricant.

The 12-volt battery is discharged. In vehicles

with the “Keyless Access” locking and ignition
system the steering remains locked and the
parking brake cannot be deactivated and the
steering column lock cannot be released if they
are connected.

If a distance above 50 km needs to be travel-

led.

There is no guarantee that the wheels will

turn smoothly or that the steering will work after
an accident.
If the vehicle cannot be towed on its wheels for
any of the reasons mentioned above, request
assistance from specialised personnel and, if
necessary, have the vehicle transported with-
out the wheels touching the ground.

Tow start

Steps to be taken prior to tow starting

Vehicles with an automatic gearbox:

 Due to

technical reasons, tow starting the vehicle is not
allowed. Attempt to start the engine using the
starting aid 

››› 

page 320

.

Vehicles with a manual gearbox:

 In general, it

is not recommended to tow start the vehicle. If
the engine does not start, try the starting aid
first 

››› 

page 320

. Please note that, in the case

of petrol engines, the maximum permitted dis-
tance for tow starting is 50 m.

 Secure the tow cable or tow bar using only

the attachment points provided for this pur-
pose.

Switch on the ignition and the hazard warning

lights.

Engage 2nd or 3rd gear while the vehicle is

stopped.

Press the clutch and hold it down.

CarManuals2.com

324

Miscellaneous situations

When both vehicles are in motion, release the

clutch pedal.

As soon as the engine starts, depress the

clutch and disengage the gear to avoid collid-
ing with the towing vehicle.

NOTICE

When tow-starting, unburnt fuel could enter
the catalytic converter and damage it.

Towing

Previous steps

Secure the tow cable or tow bar using only

the attachment points provided for this purpose 

››› 

. Depending on the equipment, these

points may be a towing device or a towing eye.

Make sure the tow cable is not twisted. Other-

wise the towing eye could unscrew during tow-
ing.

Switch on the ignition and the hazard warning

lights of both vehicles. If necessary, take into
account other different provisions that may ex-
ist in this regard.

Take into account the instructions on towing

provided in the instruction manual of the other
vehicle.

Towing vehicle (front)

Do not actually start driving until the cable is

tight.

Accelerate with particular care.

Avoid sudden braking and manoeuvres.

Vehicles with a manual gearbox:

When starting to drive, use the clutch very

gently.

Towed vehicle (behind)

Make sure the ignition is switched on so that

the steering wheel does not lock and so that, if
necessary, you can use the turn signals and the
windscreen wiper.

The brake servo and power steering only

work when the engine is running. Otherwise,
you will have to depress the brake pedal con-
siderably harder and more force will be needed
to turn the steering wheel.

Release the electronic parking brake.

Make sure the tow cable is always taut.

Disengage the gear or place the gear selec-

tor in the 

N

position.

WARNING

Never attach the tow rope or tow bar to axle
or running gear components. They could be
damaged, resulting in an accident and seri-
ous injury.

Seek specialist assistance and, if applica-

ble, have the vehicle transported on a tow
truck.

NOTICE

The vehicle can only be towed if the state of
charge of the 12-volt battery is sufficient to
disengage the electronic parking brake and
the steering column lock. If the vehicle has
no power supply or there is an electric sys-
tem fault, the engine must be jump-started
to release the electronic parking brake and
deactivate the electronic lock of the steering
column.

towing bracket, it is only allowed to tow with
a tow bar if this has been specially designed
to be installed with a tow hitch. If an unsuita-
ble tow bar is used, both the tow hitch and
the vehicle may be damaged. Instead, a tow
rope should be used.

Fuses

Introduction

In general, a fuse can be assigned to various
electrical components. Likewise, an electrical
component can be protected by several fuses.
Only replace fuses when the cause of the
problem has been solved. If a newly inserted
fuse blows after a short time, you must have
the electrical system checked by a specialised
workshop as soon as possible.

WARNING

The high voltages in the electrical system
can give serious electrical shocks, causing
burns and even death!

Never touch the electrical wiring of the ig-

nition system.

Take care not to cause short circuits in the

electrical system.

WARNING

Using unsuitable fuses, repairing fuses or
bridging a current circuit without fuses can
cause a fire and serious injury.

Never use a fuse with a higher value. Only

replace fuses with a fuse of the same amper-
age (same colour and markings) and size.

Never replace a fuse by a metal strip, sta-

ple or similar.

NOTICE

To prevent damage to the vehicle’s electri-

cal system, before replacing a fuse always
turn off the ignition, the lights and all electri-
cal elements.

Protect the fuse boxes when open to pre-

vent the entry of dust or humidity as they can
damage the electrical system.

LED technology lights

Full-LED headlights handle all light functions
(daylight, side light, turn signal, dipped beam
and route light) with light emitting diodes (LEDs)
as a light source.
Full-LED headlights are designed to last the
lifetime of the car and light bulbs cannot be
replaced. In case of headlight failure, go to an
authorised workshop to have it replaced.

The fog lights, tail lights, number plate light, side
turn signals and additional brake light are all
LED bulbs. With this in mind, they should be re-
placed by a technical service.
