Trailer towingInstructions to followYour vehicle may be used to tow a trailer when fitted with the correct equip-
ment.
If the vehicle is supplied with a factory-fitted towing bracket it will already
have the necessary technical modifications and meet the statutory require-
ments for towing a trailer. For the after-market fitting of a trailer towing
bracket see ⇒page 201.
Connectors
Your vehicle is fitted with a 12-pin connector for the electrical connection
between the trailer and the vehicle.
If the trailer has a 7-pin plug you will need to use an adapter cable. This is
available in any SEAT dealer.
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 applicable for altitudes up to
1000m above sea level. With increasing altitude the engine power and there-
fore the vehicle’s climbing ability are impaired because of the reduced air
density. The maximum trailer weight has to be reduced accordingly. The
weight of the vehicle and trailer combination must be reduced by 10% for
every 1000 m of height. The gross combination weight is the actual weight of
the laden vehicle plus the actual weight of the laden trailer. When possible,
operate the trailer with the maximum permitted drawbar load on th e ba ll jo int
of the towing bracket, but do not exceed the specified limit. The figures for
trailer weights and drawbar loads that are given on the data
plate of the towing bracket are for certification purposes only. The correct
figures for your specific model, which may be lower than these figures for the
towing bracket, are given in the vehicle documents or in ⇒Section “Tech-
nical Data”.
Distributing the load
Distribute loads in the trailer so that heavy objects are as near to the axle as
possible. Loads carried in the trailer must be secured to prevent them
moving.
Tyre pressure
Set tyre pressure to the maximum permissible pressure shown on the sticker
on the inside of the fuel tank flap. Set the tyre pressure of the trailer tyres in
accordance with the trailer manufacturer’s recommendations.
Exterior mirrors
Check whether you can see enough of the road behind the trailer with the
standard mirrors. If this is not the case, you should have additional mirrors
fitted. Both exterior mirrors should be mounted on hinged extension
brackets. Adjust the mirrors to give sufficient vision to the rear.
WARNING
Never transport people in a trailer. This could result in fatal accidents.
Note
•Towing a trailer places additional demands on the vehicle. We recom-
mend additional services between the normal inspection intervals if the
vehicle is used frequently for towing a trailer.

Trailer towing
200•Find out whether special regulations apply to towing a trailer in your
country.Ball coupling of towing bracket*Depending on the model version, the spherical head on the trailer hook may
be found in the tool box.
The ball coupling is provided with instructions on fitting and removing the
ball coupling of the towing bracket.
WARNING
The towing bracket ball coupling must be stored securely in the luggage
compartment to prevent them being flung through the vehicle and causing
injury.
Note
•By law, the ball coupling must be re moved if a trailer is not being towed
and it obscures the number plate.Driving tipsDriving with a trailer always requires extra care.Weight distribution
The weight distribution of a loaded trailer with an unladen vehicle is very
unfavourable. However, if this cannot be avoided, drive extra slowly to allow
for the unbalanced weight distribution. Speed
The stability of the vehicle and trailer is reduced with increasing speed. For
this reason, it is advisable not to drive at the maximum permissible speed in
an unfavourable road, weather or wind conditions. This applies especially
when driving downhill.
You should always reduce speed immediately if the trailer shows the slightest
sign of
snaking . Never try to stop the “snaking” by increasing speed.
Always brake in due course. If 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. Select a low gear in due course before
going down a steep downhill. This enables you to use the engine braking to
slow down the vehicle.
Reheating
At very high temperatures and during prolonged slopes, driving in a low gear
and high engine speed, always monitor the coolant temperature gauge
⇒ page 55.
Electronic Stability Programme*
The ESP* system helps to stabilise the trailer in case of skidding or rocking.

Fitting a towing bracket•Driving with a trailer involves an extra effort for the vehicle. Therefore,
before fitting a towing bracket, please contact an Authorised Service Centre
to check whether your cooling system needs modification.•The legal requirements in your country must be observed (e.g. the fitting
of a separate warning lamp).•Certain vehicle components, e.g. the rear bumper, must be removed and
reinstalled. The towing bracket securing bolts must be tightened using a
torque wrench, and a power socket must be connected to the vehicle’s elec-
trical system. This requires specialised knowledge and tools.•Figures in the illustration show the elevation value and the attachment
points which must be considered if you are retrofitting a towing bracket.WARNING
The towing brackets should be fitted at a specialised workshop.
•If the towing bracket is incorrectly installed, there is serious danger of
accident.•For your own safety, please observe the instructions provided by the
manufacturer of the towing bracket.Caution
•If the power socket is incorrectly installed, this could cause damage to the
vehicle’s electrical system.Note
For the sports model (FR, Cupra...), fitting of a trailer bracket is not recom-
mended due to the design of the bumpers.

Vehicle maintenance and cleaningGeneral notesRegular washing and care help maintain the value of your
vehicle.Vehicle maintenance
Regular care and washing help to maintain the value of the vehicle. This may
also be one of the requirements for acknowledging warranty claims in the
event of bodywork corrosion or paint defects.
The best way to protect your vehicle against the harmful effects of the envi-
ronment is through correct maintenance and frequent washing. The longer
substances such as insect remains, bird droppings, resinous tree sap, road
dirt, industrial deposits, tar, soot or road salt and other aggressive materials
remain on the vehicle, the more damage they do to the paintwork. High
temperatures (for instance in strong sunlight) further intensify the corrosive
effect.
After winter, a period when salt is put on the roads, it is impor tant to have the
underside of the vehicle washed thoroughly.
Products for vehicle maintenance
Car care products are available in your Authorised Service Centre. Keep the
product instructions until you have used them up.
WARNING
•Car care products can be toxic. Because of this, they must always be
kept closed in their original container. Keep them out of the reach of chil-
dren. Failure to comply could result in poisoning.•Always read and observe the instructions and warnings on the package
before using vehicle care products. Im proper use could cause health prob- lems or damage the vehicle. The use of certain products may produce
noxious vapours; they should be used in well ventilated areas.
•Never use fuel, turpentine, engine oil, nail varnish remover or other
volatile fluids. These are toxic and highly flammable. Risk of fire and explo-
sion.•Before washing your vehicle, or carrying out any maintenance, switch
the engine off, apply the handbrake firmly and remove the key from the
ignition.Caution
Never attempt to remove dirt, mud or dust if the surface of the vehicle is dry.
Never use a dry cloth or sponge for cleaning purposes. This could damage the
paintwork or the windows of your vehicle. Soak dirt, mud or dust with plenty
of water.

Vehicle maintenance and cleaning
204Care of the vehicle exteriorAutomatic car wash tunnel
The vehicle can normally be washed without problem in an
automatic car wash.The vehicle paintwork is so durable that the vehicle can normally be washed
without problems in an automatic car wash tunnel. However, the paintwork
wear depends to a large extent on the kind of the car wash tunnel, the
brushes used, its water filtering and the type of cleaning and preservative
products.
Before going through a vehicle wash, be sure to take the usual precautions
such as closing the windows and sunroof.
If the vehicle has special accessories such as spoilers or a roof rack or two-
way radio aerial, etc., it is advisable to consult the car wash tunnel operator.
After washing, the brakes could take some time to respond as the brake discs
and pads could be wet, or even frozen in winter. Dry the brakes by braking
several times.
WARNING
Water, ice and salt on the brakes can reduce braking efficiency. Risk of acci-
dent.
Caution
If an automatic car wash tunnel is used, before entering the tunnel, put the
aerial down parallel to the roof and do not tighten to avoid damage.
Washing by handVehicle washing
– First soften the dirt and rinse it off with water.
– Clean your vehicle from top to bottom with a soft sponge, a glove or a brush. Use very light pressure.
– Rinse the sponge or glove often with clean water.
– Special car shampoo should only be used for very stubborn dirt.
– Leave the wheels, sill panels etc. until last, using a different sponge or glove.
– Rinse the vehicle thoroughly with water.
– Dry the vehicle surface gently with a chamois leather.
–In cold temperature , dry the rubber seals and their surfaces to
prevent them from freezing. Apply silicone spray to the rubber
seals.
After washing the vehicle
– After washing, avoid sudden and sharp braking. Dry the brakes by braking several times ⇒page 193, “Braking capacity and
braking distance”.
WARNING
•Wash your vehicle with the ignition switched off.•Protect your hands and arms from cuts on sharp metal edges when
cleaning the underbody, the inside of the wheel housings etc. Risk of
injury.

•Never remove dirt, mud or dust if the vehicle surface is dry. Never use a
dry cloth or sponge for cleaning purposes. This could scratch the paintwork
or glass on your vehicle.•Washing the vehicle in low temperatures: when washing the vehicle with
a hose, do not direct water into the lock cylinders or the gaps around the
doors, tailgate, or sunroof. Risk of freezing.For the sake of the environment
To protect environment, the vehicle should be washed only in specially
provided wash bays. This prevents toxic, oil-laden waste water entering the
sewerage system. In some places, washing vehicles outside wash bays is
prohibited.
Note
Do not wash the vehicle in direct sunlight.Washing the vehicle with a high pressure cleaner
Be particularly careful when using a high pressure cleaner!– Always observe the instructions for the high-pressure cleaner, particularly those concerning the pressure and the spraying
distance. – Increase the spraying distance
for soft materials and painted
bumpers.
– Do not use a high pressure cleaner to remove ice or snow from windows ⇒page 206.
– Never use concentrated jet nozzles (“rotating jets”) ⇒.
– After washing, avoid sudden and sharp braking. Dry the brakes by braking several times ⇒page 193.
WARNING
•Never wash tyres with a concentrated jet (“rotating nozzle”). Even at
large spraying distances and short cleaning times, visible and invisible
damage can occur to the tyres. This may cause an accident.•Water, ice and salt on the brakes can reduce braking efficiency. Risk of
accident.Caution
•Do not use water hotter than 60 °C. This could damage the vehicle.•To avoid damage to the vehicle, keep a sufficient distance from sensitive
materials such as flexible hoses, plastic, soundproofing material, etc. This is
also important for bumpers painted in the colour of the bodywork. The closer
the nozzle is to the surface, the greater the wear on the material.Vehicle paint maintenance
Regular waxing protects the paintwork.You need to apply wax to your vehicle if water does not form small drops and
run off the paintwork when it is clean.
WARNING (continued)

Vehicle maintenance and cleaning
206Good quality hard wax products are available at your Authorised Service
Centre.
Regular wax applications help to protects the paintwork from environmental
contaminants. ⇒page 203. It also protects against minor scratches.
Even if a wax solution is used regularly in the vehicle washing tunnel, it is
advisable to protect the paint with a hard wax coating at least twice a year.Polishing the paintwork
Polishing brings back gloss to the paintwork.Polishing is only necessary if the paint has lost its shine, and the gloss cannot
be brought back by applying wax. Polishing products can be purchased in
your Authorised Service Centre.
The vehicle must be waxed after polishing if the polish used does not contain
wax compounds to seal the paint ⇒page 205, “Vehicle paint maintenance”.
Caution
To prevent damage to the paintwork:•Do not use polishes and hard wax on painted parts with a matte finish or
on plastic parts.•Do not polish your vehicle in a sandy or dusty environment.Caring for plastic parts
Solvents damage plastic parts.If normal washing fails to clean plastic parts, clean them with approved
solvent-free plastic cleaning and care products.
Caution
•The use of liquid air freshener directly over the air vents of the vehicle may
damage the plastic parts if the liquid is accidentally spilled.•Cleaning products which contain solvents will damage the material.Cleaning windows and exterior mirrorsCleaning windows
– Moisten the windows with commercially available, alcohol based glass cleaner.
– Dry the windows with a clean chamois leather or a lint-free cloth.
Removing snow
– Use a small brush to remove sn ow from the windows and mirrors.
Removing ice
–Use a de-icer spray.Use a clean cloth or chamois leather to dry the windows. The chamois
leathers used on painted surfaces are not suitable to clean windows because
they are soiled with wax deposits which could smear the windows.
If possible, use a de-icing spray to remove ice. If you use an ice scraper, push
it in one direction only without swinging it.
Use window cleaner or a silicone remover to clean rubber, oil, grease and sili-
cone deposits off.
Wax deposits can be removed with a special cleaner available in your Author-
ised Service Centre. Wax deposits on the windscreen could cause the wiper
blades to judder. Adding a window clea ner that dissolves wax to the wind-

window. To prevent damage, do not put stickers on the heating elements
inside the window.Cleaning windscreen wiper bladesClean wiper blades improve visibility.
1. Use a soft cloth to remove dust and dirt from the windscreen wiper blades.
2. Use window cleaner to clean the windscreen wiper blades. Use a sponge or a cloth to remove stubborn dirt.Rubber seals maintenance
If rubber seals are well looked after, they will not freeze so
quickly.1. Use a soft cloth to remove dust and dirt from the rubber seals.
2. Apply a specialist care product to the rubber seals.
The rubber strips on the doors, windows, bonnet and tailgate will remain
pliable and last longer if they are treated with a suitable care product (for
example silicone spray).
Caring for rubber seals will also prevent premature ageing and leaks. The
doors will be easier to open. If rubber seals are well looked after, they will not
freeze so quickly in winter.Door lock cylinders
The door lock cylinders can freeze up in winter.To de-ice the lock cylinders you should only use spray with lubricating and
anti-corrosive properties.Cleaning chrome parts1. Clean chrome parts with a damp cloth.
2. Polish chrome parts with a soft, dry cloth.If this does not provide satisfying results, use a specialist chrome cleaning
product . Chrome cleaning products will remove stains from the surface.
Caution
To prevent scratching chrome surfaces:•Never use an abrasive cleaning product on chrome.•Do not clean or polish chrome parts in a sandy or dusty environment.

Alloy wheelsEvery two weeks
– Wash salt and brake dust from alloy wheels.
– Use an acid free detergent to clean the wheel rims.
Every three months
– Apply a hard wax compound to the wheels.Alloy wheels require regular attention to preserve their appearance. If road
salt and brake dust are not often removed, the aluminium finish will be
impaired. Always use an acid-free detergent for alloy wheels.
Car polish or other abrasive agents should not be used. If the protective
coating is damaged, e.g. by flying stones, the damaged area should be
repaired immediately.

Underbody protection
The vehicle underbody is coated to protect it from chemical
and mechanical damage.The protective coating can be damaged when driving. We recommend you to
check the protective coating under the body and on the running gear, and
reinstated if necessary, before and after the winter season.
We recommend you to go to your Authorised Service Centre to carry out repair
work and additional anti-corrosion work.
WARNING
Do not apply underseal or anti-corrosion coatings to the exhaust pipes,
catalytic converter or the heat shields on the exhaust system. The heat of
the exhaust system or the engine could cause them to ignite. Risk of fire.
