thrown around the vehicle interior. This could cause serious injuries to
passengers and cause the driver to lose control of the vehicle.
xDo not transport animals or place hard, heavy or sharp objects inside
the vehicle in: open storage compartments, instrument panel, storage tray,
items of clothing or bags.
xWhile driving, always keep object compartments closed.
WARNING
Objects falling into the driver's footwell could prevent use of the pedals.
This could lead the driver to lose control of the vehicle, increasing the risk
of a serious accident.
xMake sure the pedals can be used at all times, with no objects rolling
underneath them.
xThe floor mat should always be secured to the floor.
xNever place other mats or rugs on top of the original mat supplied by
the factory.
xMake sure that no objects can fall into the driver's footwell while the
vehicle is in motion.
Caution
xObjects on the shelf could chafe against the wires of the heating element
in the rear window and cause damage.
xDo not keep heat-sensitive objects, food or medicines inside the vehicle.
Heat and cold could damage them or render them useless.
xLight-transparent objects placed inside the vehicle, such as lenses,
magnifying glasses or transparent suction caps on the windows, could
concentrate the sun's rays and cause damage to the vehicle.

Pedals
Do not allow floor mats or other objects to obstruct the free passage of the
pedals.Floor mats should leave the pedal area free and unobstructed and be
correctly secured in the footwell zone.
In the event of failure of a brake circuit, the brake pedal must be pressed
harder than normal to brake the vehicle.
WARNING
Objects falling into the driver's footwell could prevent use of the pedals.
This could lead the driver to lose control of the vehicle, increasing the risk
of a serious accident.
xMake sure the pedals can be used at all times, with no objects rolling
underneath them.
xAlways secure the mat in the foot well.
xNever place other mats or rugs on top of the original mat supplied by
the factory.
xEnsure that no objects can fall into the driver's footwell while the
vehicle is in motion.
Caution
The pedals must always have free and unobstructed passage to the floor. For
example, in case of a fault in the brake circuit, the brake pedal will need to be
pressed further to stop the vehicle. To press the brake pedal down further will
require more force than usual.

xWhen the brake pedal is released or when the brake force is reduced, ABS
is turned off.
ABS control can be observed by vibration of the brake pedal and noise. You
should never expect the ABS to reduce the braking distance under any
circumstances. Braking distances will increase when driving on gravel, recent
snow or on icy and slippery ground.
When driving on loose ground, the all-terrain configuration of the ABS is auto-
matically turned on. When ABS is activated, the front wheels may lock briefly.
This shortens the braking distance in off-road situations as the wheels are
prevented from digging into loose surfaces. All-terrain ABS only intervenes
when driving in a straight line. When the front wheels are turned, the normal
ABS is activated.
Braking assist system (BAS)
The brake assist system may reduce the required braking distance. The brake
assist system boosts the braking force if you press the brake pedal quickly in
an emergency. As a result, the braking pressure increases rapidly, the braking
force is multiplied and the braking distance is reduced. This enables the ABS
to be activated more quickly and efficiently.
¡Do not lift your foot off the brake pedal! When the brake pedal is released or
when the brake force is reduced, braking assist automatically turns off the
brake servo.
Traction control when accelerating (TCS)
In the event of wheelspin, the traction control system reduces the engine
torque to match the amount of grip available. The TCS makes some situations
easier, for example, when starting, accelerating or going uphill, even in unfa-
vourable road conditions.
The TCS can be switched on or off manually Ÿpage 218.
Electronic differential lock system (EDS)
EDS is available when driving in straight lines under normal conditions. When
the EDL detects wheelspin, it brakes the spinning wheel and directs the power to the other driven wheels. To prevent the disc brake of the braked
wheel from overheating, the EDL cuts out automatically if subjected to exces-
sive loads. The EDL will switch on again automatically when the brake has
cooled down.
WARNING
Driving at high speed on icy, slippery wet ground can result in loss of
vehicle control and serious injury to the driver and passengers.
xAdjust your speed and driving style to visibility, road, traffic and
weather conditions. Even though the braking assist systems, ABS, BAS,
EDS, TCS and ESP, provide more security, do not take unnecessary risks
while driving.
xBraking assist systems can not overcome the laws of physics. Even with
ESP and other systems, slippery and wet roads will always be dangerous.
xDriving to quickly on wet ground can result in the wheels losing contact
with the ground in an effect known as aquaplaning. Without adherence, it
is impossible to brake, steer or control the vehicle.
xBraking assist systems cannot avoid accidents if, for example, the
driver does not respect safety distances or drives to quickly in difficult
conditions.
xEven though braking assist systems are extremely effective and help
control the vehicle in difficult situations, remember that the vehicle
stability depends on tyre grip.
xWhen accelerating on a slippery surface, for example on ice and snow,
press the accelerator carefully. The wheels can still slip even with braking
assist systems resulting in loss of vehicle control.
WARNING
The effectiveness of the ESP can be considerably reduced if other compo-
nents and systems affecting driving dynamics are not maintained or are not

Trailer towing 258
Trailer towing
Introduction
Always be aware of the legal requirements for each country to drive with a
trailer and to use a trailer bracket.
Your car is intended mainly for transporting passengers however, it can also
be used to tow a trailer provided that it is fitted with the necessary equip-
ment. The additional load has an effect on the useful life, fuel consumption
and the vehicle performance and, in some cases, reduce the service intervals.
Driving with a trailer requires more force from the vehicle and, thus, more
concentration from the driver.
For wintertime temperatures, fit winter tyres to the vehicle and the trailer.
Drawbar load
The maximum permitted Drawbar load exerted by the trailer drawbar on the
ball joint of the tow hitch must not exceed 100 kg (approximately 220 lbs).
Vehicles with the Start-Stop function
With a SEAT factory fitted or retrofitted trailer bracket, the Start-Stop function
is automatically deactivated when a trailer is connected. For trailer brackets
not installed by SEAT, the Start-Stop function must be deactivated manually
using a button located on the dashboard before driving with a trailer and it
must remain off for the entire journey Ÿ.

WARNING
Never transport people in a trailer: this will endanger in their life and is
against the law.
WARNING
The incorrect use of the tow hitch can cause accidents and injury.
xOnly use a tow hitch in good condition and correctly installed.
xNever change or repair a tow hitch.
xTo reduce the risk of injury in case of a reversing collision, injury to
pedestrians and cyclists when parking, always keep the ball joint in when
a trailer is not being used.
xNever fit a trailer tow hitch “that distributes the load” or “balances the
load”. Your vehicle has not been designed for this type of tow hitch. The
tow hitch may fail and the trailer will separate from the vehicle.
WARNING
Driving with a trailer and transporting heavy or large objects can affect
vehicle handling and even cause an accident.
xAlways secure loads correctly with suitable and undamaged attach-
ment rope or straps.
xAdjust your speed and driving style to visibility, road, traffic and
weather conditions.
xTrailers with a high centre of gravity can overturn more easily than
trailers with a low centre of gravity.

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.

The warning lamp
xWhen the indicator flashes, the tow ball is not in its final position, has not
engaged or is damaged Ÿ.
xWhen the indicator remains lit and the tailgate is open, the tow ball has
inserted correctly into the folded or deployed position.
xWhen the tailgate is closed, the indicator is turned off.
WARNING
The incorrect use of the tow hitch can cause accidents and injury.
xEnsure that no person, animal or object gets in the way of the tow ball.
xNever push the button when there is a trailer hitched or when any kind
of carrier or accessory is fitted to the tow hitch ball.
xWhile the ball is moving, do not interfere with any tool.
xDo not drive with a trailer if the indicator does not light.
xIf there is a fault in the electric system or the trailer tow hitch, visit a
specialist workshop to have it checked.
xIf the diameter of the tow hitch is less than 49 mm, never use this for a
trailer.
Caution
xIf anything is attached to the tow hitch ball, do not, under any circum-
stances press the button.
xNever direct a high-pressure or steam cleaning system directly at the tow
hitch ball or trailer power socket. This could cause damage to seals or remove
lubricating grease.
Note
In extremely low temperatures, it is possible that the tow hitch is not
released. In this case, place the vehicle in a warmer location (for example, a
garage).
Installing a bicycle carrier to the tow hitch
The maximum load permitted for a bicycle carrier on the tow hitch ball is 75
kg, with a maximum distance of 300 mm from the support. The distance
between supports is the distance between the bicycle carrier centre of gravity
(with the bicycles) and the centre of point of the tow hitch ball.
WARNING
The incorrect use of the tow hitch with a bicycle carrier installed can cause
accidents and injury.
xNever exceed the load and distances between supports indicated.
xNever fit the bicycle carrier to the tow hitch ball neck, underneath the
tow hitch given that the bicycle carrier may be incorrectly fitted due to the
shape of the tow hitch and the model of bicycle carrier.
xAlways read and take the manufacturer assembly instructions into
account.
Caution
Exceeding the maximum load and distance between supports indicated can
cause considerable damage to the vehicle.
xNever exceed the specifications.
Hitching and connecting the trailer
Trailer cable
Always secure the trailer cable to the towing vehicle correctly. Leave a little bit
of slack in the cable for turning. However, ensure that the cable does not rub
off the ground while driving.

Trailer towing 264
Loading the trailer
Trailer weight / drawbar load
The trailer weight is the load that the vehicle can pull Ÿ. The drawbar load
is the vertical weight of the trailer hitch on the tow hitch ball Ÿpage 267.
The figures for trailer weights and draw bar weights given on the data plate of
the towing bracket are for values of this model only. The correct figures for
your specific vehicle, which may be lower than these figures for the tow hitch,
are given in the registration documents. The instructions in the official
vehicle documents take precedence.
For the sake of road safety, SEAT recommends using the maximum allowed
drawbar load. The handling of the combined vehicle and trailer will be poor if
the drawbar load is too low.
The drawbar load increases the weight on the rear axle, reducing the vehicle
carrying capacity.
Gross combination weight
This figure refers to the combined weight of the loaded vehicle and loaded
trailer.
Loading the trailer
The combined vehicle and trailer must be balanced. Use the maximum
drawbar load authorised and do not overload the front or the rear of the
trailer:
xDistribute loads in the trailer so that heavy objects are as near to the axle
as possible or even above it.
xCorrectly secure the trailer load.
Tyre pressure
Inflate the trailer tyres according to the manufacturer's instructions.
Inflate the towing vehicles tyres to the maximum Ÿpage 323.
WARNING
Exceeding the maximum authorised axle load, drawbar load or the gross
combination weight of the towing vehicle and trailer could cause a serious
accident with severe consequences.
xNever exceed the specifications.
xWith the actual load on the front and rear axles, the maximum axle load
should never be exceeded. The weight on the front and rear should never
exceed the gross vehicle weight.
WARNING
If the load moves, the stability and safety of the vehicle and trailer combi-
nation will be seriously affected and this could result in a serious accident.
xAlways correctly load the trailer.
xAlways secure loads correctly with suitable and undamaged attach-
ment rope or straps.
Driving with a trailer
Adjusting the headlights
When towing a trailer, the front of the vehicle may rise and so the dipped
beam headlights may blind other drivers. Use the headlight range control to
lower the cone of light. If you do not have headlight range control, have the
headlights adjusted by a qualified dealership. Vehicles with high-intensity
discharge lamps adapt automatically and do not require adjustment.
Details of driving with a trailer
xIf the trailer has an overrun brake, apply the brakes gently at first and
then, firmly. This will prevent the jerking that can be caused by the trailer
wheels locking.

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)
