Driving and the environment 254
Unnecessary short journeys should be avoided. Try to combine trips.
The vehicle uses more fuel in winter than in summer, even when other condi-
tions are the same.
“Warming” the engine is not only forbidden in some countries, but in practice
it is technically superfluous as it is a waste of fuel.
Adjusting type pressures.
Having the correct pressure in your tyres helps to reduce rolling resistance
and, as a result reduces fuel consumption. Increasing the tyre pressure
slightly (+ 0.2 bar / + 3 psi) can help to save fuel.
If you are prepared to accept a slight reduction in comfort, the tyres may be
filled to the pressures recommended for a fully-loaded vehicle. This is also
valid when driving alone without luggage.
When you buy new tyres, make sure they are optimised for minimum rolling
resistance.
Use low friction engine oil
The use of low viscosity totally synthetic oils, known as low friction engine oil,
help to reduce fuel consumption. Low friction engine oils reduce the resist-
ance caused by friction in the engine, they flow around the engine more
quickly and efficiently, particularly in cold starts. The effect is particularly
noticeable in vehicles frequently used for short journeys.
Always check the engine oil level and observe service intervals (engine oil
change intervals).
When purchasing engine oil, always observe legal requirements and ensure
that the oil is approved by SEAT.
Avoid carrying unnecessary loads
The lighter the vehicle, the more economical and ecological the driving style.
For example, an additional weight of 100 kg will increase fuel consumption
up to 0.3 l/100 km.
Remove any unnecessary objects or loads from the vehicle.Remove optional equipment and unnecessary accessories
The more aerodynamic the vehicle, the lower the fuel consumption. Optional
equipment and accessories (such as roof racks or bike carriers) reduce the
aerodynamic benefits of the vehicle.
Therefore, we recommend you remove all optional and unnecessary equip-
ment and racks, especially if you intend to drive at high speeds.

Trailer towing 260
Driving with a trailer
Technical requirements
If the car is supplied with a factory-fitted tow hitch it will already have the
necessary technical modifications and meet the statutory requirements for
towing a trailer.
Only use an approved trailer hitch for the gross trailer weight rating. The tow
hitch must be suitable for both the vehicle and trailer and must be securely
fitted to the vehicle chassis. Only use a tow hitch with a removable ball joint.
Always check and take into account the tow hitch manufacturer's instruc-
tions. Never fit a trailer tow hitch “that distributes the load” or “balances the
load”.
Bumper mounted tow hitch
Never fit a tow hitch or its attachments to the bumper. A tow hitch should
never interfere with the bumper performance. Do not modify the exhaust
system and brake system. Regularly check the tow hitch to ensure it is firmly
fitted.
Engine cooling system
Driving with a trailer increases the load on the engine and cooling system.
The cooling system should always have sufficient coolant and to be able to
cope with the vehicle and trailer.
Electric trailer brake
If the trailer has its own braking system, please note the relevant legal
requirements. The trailer braking system should never be connected to the
vehicle braking system.
Trailer cable
Always use a cable between the vehicle and the trailer Ÿpage 262.Trailer rear lights
The rear lights of a trailer must fulfil the corresponding standards
Ÿpage 262.
Never connect the trailer's rear lights directly to the vehicle electric system. In
case of any doubt about the electrical connection of the trailer, ask a
specialist workshop. SEAT recommends visiting a qualified workshop.
Wing mirrors
When the field of vision behind the trailer cannot be seen using the standard
wing mirrors of the towing vehicle, additional wing mirrors are required
according to the legal requirements of each country. The wing mirrors must
be fitted before driving and must provide a sufficient field of vision behind.
Trailer electricity consumption
Never exceed the specifications:
WARNING
If the tow hitch is badly fitted or unsuitable, the trailer may separate from
the vehicle causing an accident with serious consequences.
Caution
xIf the rear lights of the trailer are not correctly connected, the vehicle elec-
tronics may be damaged.

Safety FirstOperating instructionsPractical tipsTe c h n i c a l D a t a Trailer electric socket
The electric connection between vehicle and trailer is a 13-pin socket. If the
trailer plug has seven pins, an adapter cable must be used.
Trailer rear lights
Check the trailer rear lights to ensure they work correctly and remain legal.
Ensure that the trailer does not use more than the maximum power
Ÿpage 260.
Trailer connected to the antitheft alarm:
xWhen a vehicle comes from the factory fitted with an antitheft alarm and
tow hitch.
xWhen the trailer is connected to the vehicle using the socket.
xWhen the vehicle and trailer electrical systems work correctly and are not
damaged.
xWhen the vehicle is locked using the vehicle key and the antitheft alarm
is turned on.
When the vehicle is locked, the alarm is triggered when the electrical connec-
tion between the vehicle and the trailer is removed.
Always turn off the anti-theft alarm system before connecting or discon-
necting a trailer. Otherwise, the tilt sensor may erroneously activate the
alarm.
WARNING
Erroneous or unsuitable connection of electric cables may supply energy to
the trailer causing an anomaly in the vehicle electronics that could result
in an accident with serious consequences.
xAll work on the electrical system must be carried out only by a
specialist workshop.
xNever connect the trailer's electric system to the electrical connections
of the rear lights or any other power sources.
Caution
Do not leave the trailer connected to the vehicle when parked; places on its
support wheel or its supports. For example, when changing the load or a
puncture, the vehicle will be pushed up or down. The force acting on the tow
hitch and the trailer could damage the vehicle or the trailer.
Note
In case of a fault in the vehicle or trailer electrical system or in case of prob-
lems with the antitheft alarm system, have the system checked by a specialist
workshop.
Note
If the trailer accessories use energy from the socket when the engine is
stopped, the battery will be discharged.
Note
For technical reasons, trailers fitted with rear LED lights cannot be connected
to the antitheft alarm system.
Note
If the vehicle battery is running low, the electrical connection with the trailer
is automatically cut.
Note
With the engine running, the electrical equipment on the trailer will consume
power.

Vehicle maintenance and cleaning 278
Caring for and cleaning the vehicle interior
Introduction
The dye from many items of modern clothing (e.g. dark jeans) is not always
solid enough. Seat upholstery (material and leather), especially when light-
coloured, may visibly discolour if the dye comes out of clothing (even when
used correctly). This is not an upholstery defect but indicates that the dye in
the item of clothing is not solid enough.
Additional information and warnings:
xCaring for and cleaning the vehicle exterior Ÿpage 269
xAccessories, parts replacement, repairs and modifications Ÿpage 285
WARNING
Car care products may be toxic and hazardous. If car care products are not
suitable or are used inappropriately, this could result in accident, serious
injury, burns or intoxication.
xCar care products must always be stored in the original container which
should be kept closed.
xObserve information provided by the manufacturer.
xTo prevent confusion, never store car care products in empty food cans,
bottles or other containers.
xKeep all care products out of reach of children.
xHarmful vapours may be produced when using car care products. There-
fore, care products should only be used in well-ventilated spaces or in the
open air.
xNever use fuel, turpentine, engine oil, acetone or any other volatile
liquid to wash, clean or care for the vehicle. These are toxic and highly
flammable.
WARNING
Inappropriate care and cleaning of vehicle components may effect the
vehicle safety equipment, increasing the risk of severe injury.
xVehicle components should only be cleaned and maintained in accord-
ance with the manufacturer's instructions.
xOnly use approved or recommended care products.
Caution
xCleaning products which contain solvents will damage the material.
xTo avoid damage, stubborn stains should be removed by a specialist
cleaning company.
Note
Suitable car care products are available from your Technical Service.
Treating your upholstery
Check list
For information on how to treat and care for the vehicle upholstery, please
bear the following in mind Ÿ:
xBefore entering the vehicle, fasten all Velcro fastenings which could come
into contact with upholstery and coverings. If the Velcro fastenings on uphol-
stery and material covers are not securely fastened, this could damage them.
xTo prevent damage, do not allow the upholstery or covers to come into
contact with sharp or decorative objects. Decorative objects such as zips,
rivets and rhinestones on clothing and belts.
xDust and grit in the pores and seams should be removed regularly to
prevent them scratching and damaging the surface.

Accessories, parts replacement and modifications 288
xNever fit recycled or reused airbag components in your vehicle.
WARNING
Modifications to the vehicle suspension, including the use of unauthorised
wheel and tyre combinations, may affect the performance of the airbags
and increase the risk of serious or fatal injury in the event of accident.
xNever fit suspension components which are not identical to the original
parts mounted in the vehicle.
xNever use wheel and tyre combinations not approved by SEAT.
Retro-fitting of two-way radios
An exterior aerial is required for the use of two-way radios in the vehicle.
The retro-fitting of electrical or electronic appliances in the vehicle is subject
to their approval for use in your vehicle. Under certain circumstances, this
could mean that your vehicle registration documents are no longer valid.
SEAT has approved your vehicle for use with two-way radios providing the
following conditions are observed:
xThe exterior aerial must be mounted professionally.
xThe maximum transmitting power is 10 watts.
An only external aerial is needed to give the equipment its optimal reach.
Check first with a qualified dealer if you wish to use a two-way radio with a
transmitting power of over 10 watts. The qualified workshops are familiar
with the technical options for installation. SEAT recommends visiting a quali-
fied workshop.All legal requirements, together with the instructions for the use of two-way
radios must be observed.
WARNING
If the two-way radio is not securely fastened in position, it could be sent
flying around the vehicle in the event of sharp braking, sudden manoeuvres
or accident, causing injury.
xWhile driving, two-way radios must be securely fastened in position,
outside the radius of action of the airbags, or safely stowed away.
WARNING
When using a two-way radio without a connection to an exterior aerial, the
maximum permitted levels of electromagnetic radiation may be exceeded.
This is also the case if the aerial has not been correctly installed.
xYou should only use a two-way radio inside the vehicle if it has first
been correctly connected to an exterior aerial.
Information stored by the control units
Your vehicle is fitted at the factory with a series of electronic control units
responsible for the engine and gearbox management. In addition, the control
units supervise the performance of the exhaust gas system and the airbag
systems.
Therefore, while the vehicle is being driven, these electronic control units are
continuously analysing the vehicle data. In the event of faults or deviations
from the theoretical values, only this data is stored. Normally, the warning
lamps on the instrument panel light up in the event of faults.
This data can only be read and analysed using special equipment.
WARNING (continued)

Checking and refilling levels 294
Follow the legal requirements for the use, storage and transport of
spare fuel canisters.
Insure that the fuel container complies with manufacturing stand-
ards, for example, ANSI or ASTM F852-86.
Caution
xAlways remove any fuel spilled on the vehicle paintwork immediately to
avoid damage to the wheel housing, the tyre and vehicle paintwork.
xRefuelling a petrol engine with diesel or a diesel engine with petrol can
cause serious engine and fuel system damage; the resulting malfunctions
are not covered 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. You should obtain professional assistance. With the engine running, the
composition of the wrong fuel could significantly damage the fuel system and
the engine itself.
xIn vehicles with a diesel engine, under no circumstances should you
refuel or drive with petrol, kerosene, heating oil or any other type of different
fuel. Other types of fuels could cause serious damage to the engine and to
the fuel supply system and the resulting problems are not covered by the
SEAT warranty.
For the sake of the environment
Fuels can contaminate the environment. Collect any spilt service fluids and
allow a professional to dispose of them.
Note
There is no emergency mechanism for the manual release of the tank flap. If
necessary, request assistance from specialised personnel.
Control lamps and fuel gauge
Several warning and control lamps should light up for a few seconds when
the ignition is switched. This signals that the lamp is working properly. They
will switch off after a few seconds.
The auxiliary heater and the auxiliary heater running off petrol will automati-
cally switch off when the indicator

Checklist
Never work on the engine or in the engine compartment if you are not familiar
with the operations to be carried out, the applicable safety standards and
especially if you do not have the instruments, liquids and tools necessary
Ÿpage 304, “Working in the engine compartment”! Have the work carried
out by a qualified workshop if you are uncertain. Check the following regu-
larly, preferably when you refuel:
xWindscreen washer fluid level Ÿpage 124
xEngine oil level Ÿpage 309
xEngine coolant level Ÿpage 313
xBrake fluid level Ÿpage 210
xTyre pressure Ÿpage 323

– Side lights, dipped headlights and full beam headlights
– Rear lights
–Brake lights
– Rear fog light Ÿpage 116
WARNING
Not following the checklist prepared for your own safety could lead to acci-
dents and severe injuries.
xAlways follow the check list and perform the necessary operations.

Checking and refilling levels 298
If good quality petrol with additives is not available or engine problems arise,
the necessary additives must be added when refuelling.
Not all petrol additives have been shown to be effective. The use of unsuit-
able petrol additives could damage the engine. These additives are available
from qualified workshops, who will inform you of their application.
Caution
xOnly use fuel with an octane rating that is in line with the norm EN 228,
otherwise significant damage could be caused to the engine and fuel system.
Furthermore, it could lead to a loss of performance with the consequent
engine fault.
xThe use of unsuitable petrol additives could damage the engine.
xIf, in exceptional circumstances, petrol with a lower octane rating to that
recommended is used, only use moderate engine speeds and a light throttle.
Avoid using full throttle and overloading the engine. Otherwise you may
damage the engine. Fill up with fuel of a suitable octane rating as soon as
possible.
xDo not refuel if the filler indicates that the fuel contains metal. LRP (lead
replacement petrol) fuels also contain high concentrations of metal addi-
tives. This could damage the engine!
xJust one full tank of leaded fuel would seriously impair the efficiency of
the catalytic converter and could damage it.
Diesel
Diesel fuel
Diesel fuel must correspond to European standard EN 590 (In Germany, EN
590 or DIN 51628).
The use of diesel fuel with a high sulphur percentage requires shorter service
intervals ŸBooklet “Maintenance Programme” Ÿ. Your qualified work-shop will be able to tell you which countries have diesel with a high sulphur
content.
Do not mix fuel additives (thinners, or similar additives) with diesel fuel.
Winter-grade diesel
When using “summer-grade diesel fuel”, difficulties may be experienced at
temperatures below 0 °C (+32 °F) because the fuel thickens due to wax sepa-
ration. For this reason, “winter-grade diesel fuel” is available in Germany, for
example, during the cold months. It can be used at temperatures as low as
-20 °C (-4 °F).
In countries with different climatic conditions, other types of diesel fuel are
available that are suitable to local temperatures. SEAT qualified workshops
and filling stations in the country concerned will inform you on the type of
diesel fuels available.
A cold diesel engine makes more noise during winter temperatures than
summer temperatures. Furthermore, the exhaust fumes may turn slightly
bluish while the engine is heating. The quantity of exhaust gases will depend
on the outside temperature.
Filter pre-heater
Vehicles with a diesel engine are fitted with a fuel filter pre-heater. This
ensures that the fuel system remains operational to approx. -24 °C (-11.2 °F),
provided you use winter-grade diesel which is safe to -15 °C (+5.00 °F).
However, if the fuel has waxed to such an extent that the engine will not start
at temperatures of under -24 °C (-11.2 °F), simply place the vehicle in a warm
garage or workshop for a while to heat up.
Auxiliary heater
Vehicles with a diesel engine may be fitted with an auxiliary heater. The
heater runs off the fuel from the fuel tank. On doing so, smells and steam may
be noticed outside the vehicle for a short period. This is normal and it is not
an indication of a fault in the vehicle.

Checking and refilling levels299
Safety FirstOperating instructionsPractical tipsTe c h n i c a l D a t a Whenever there is little fuel in the tank (reserve), the auxiliary heater auto-
matically switches off.
WARNING
Never use start boosters. An aerosol start booster could explode or cause
a sudden rise in engine speed leading to engine damage and serious injury.
Caution
xThe vehicle is not prepared for the use of biodiesel. Under no circum-
stances should this fuel be used. It could damage the fuel system and subse-
quently lead to engine faults!
xThe addition of biodiesel to diesel by the diesel producer according to
Standard EN 590 or other equivalent (DIN 51628 in Germany, for example) is
authorised and causes no type of damage to the engine or the fuel system.
xThe diesel engine has been designed for to use diesel fuel exclusively.
Therefore, never use petrol, fuel oil or other unsuitable fuels. The composition
of these fuels may significantly damage the fuel system and the engine.
xThe use of diesel fuels with a high sulphur percentage could considerably
reduce the service life of the diesel particulate filter. Your qualified workshop
will be able to tell you which countries have diesel with a high sulphur
content.
Information on fuel consumption
The consumption and emission values indicated do not refer to one specific
vehicle. They are only to be used to compare the values of the different
vehicle versions. The fuel consumption and CO
2 emissions of a vehicle not
only depend on the effective use of fuel. They also depend on your driving
style and other non-technical factors.Calculating fuel consumption
Fuel consumption and emission values are determined according to the
current version of the 715/2007/EC or 80/1268/EEC regulation and are valid
for the vehicle kerb weight. The specifications do not refer to an individual
vehicle. Two measuring cycles are carried out on a rolling road test bed. The
test criteria are as follows:
Note
The kerb weight may vary according to the vehicle equipment. This could
raise consumption and the CO
2 emissions slightly.
Note
In practice, consumption values could be different to the values calculated
based on the 715/2007/EC or 80/1268/EEC regulations.
Urban cycleMeasurement of the urban cycle starts with an engine cold
start. City driving is then simulated at between 0 and 50
km/h.
Road cycleIn the road cycle simulation, the car undergoes frequent
acceleration and braking in all gears, as in normal everyday
driving. The road speed ranges from 0 to 120 km/h.
CombinedThe average combined consumption is calculated with a
weighting of around 37 % for the urban cycle and 63 % for
the road cycle.
CO2 emis-
sions of the
combination The exhaust gases are collected during both driving cycles to
calculate carbon dioxide emissions (urban and road). The
gas composition is then analysed to evaluate the CO
2 con-
tent and other emissions.
