Trailer towing
Trailer towing Instructions to follow
Your vehicle may be used to tow a trailer when fitted with the correct equip-
ment.
If the car is supplied with a factory-fitted towing bracket it will already have
the necessary technical modifications and meet the statutory requirements
for towing a trailer. If you wish to retrofit a towing bracket, consult
⇒ page 196.
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 correspond-
ingly steeper slopes.
The maximum trailer weights listed are only applicable for altitudes up to
1000 m above sea level. With increasing altitude the engine power and
therefore 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 further 1000 m (or part thereof). 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 the ball joint 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 ⇒ chapter 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 mov-
ing.
Tyre pressure
Set tyre pressure to the maximum permissible pressure shown on the stick-
er 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 brack-
ets. 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 ve-
hicle is used frequently for towing a trailer.
● Find out whether special regulations apply to towing a trailer in your
country. 

569 mm
875 mm
1040 mm
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. 

Vehicle maintenance and cleaning
Vehicle maintenance and cleaning General notes
Regular 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 materi-
als 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 important 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 pack-
age before using vehicle care products. Improper use could cause health
problems or damage the vehicle. The use of certain products may pro-
duce 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 ex-
plosion.
● 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.
For the sake of the environment
● When purchasing products for your vehicle maintenance, select the
ones which are not harmful to the environment.
● The waste from car care products should not be disposed of with ordina-
ry household waste. Observe the disposal information on the package. 

202Vehicle maintenance and cleaning
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.
Good quality hard wax products are available at your Authorised Service
Centre.
Regular wax applications help to protects the paintwork from environmental
contaminants. ⇒ page 199. 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 can-
not 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 con-
tain wax compounds to seal the paint ⇒ page 202, Vehicle paint mainte-
nance.
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
sol-
vent-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 mirrors
Cleaning 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 snow from the windows and mir-
rors.
Removing ice
– Use a de-icer spray.
Use a clean cloth or chamois leather to dry the windows. The chamois leath-
ers used on painted surfaces are not suitable to clean windows because
they are soiled with wax deposits which could smear the windows. 

203
Vehicle maintenance and cleaning
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
silicone deposits off.
Wax deposits can be removed with a special cleaner available in your Au-
thorised Service Centre. Wax deposits on the windscreen could cause the
wiper blades to judder. Adding a window cleaner that dissolves wax to the
windscreen washer fluid prevents wiper blades from juddering, but wax de-
posits are not removed.
CAUTION
● Never use warm or hot water to remove snow and ice from windows and
mirrors. This could cause the glass to crack!
● The heating element for the rear window is located on the inner side of
the window. To prevent damage, do not put stickers on the heating ele-
ments inside the window. 
Cleaning windscreen wiper blades
Clean 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 parts
1. 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. 
Safety FirstOperating InstructionsPractical TipsTechnical Specifications

204Vehicle maintenance and cleaning
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. 
Steel wheel rims
– Clean steel wheel rims regularly using a separate sponge.
Use an industrial cleaner to remove brake dust. Any damage to the paint on
steel wheel rims should be repaired before starting to rust.
WARNING
● Never wash tyres with a cylindrical jet. Even at large spraying distan-
ces 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. Directly after washing, avoid sudden and sharp braking.
“Dry” the brakes by braking several times ⇒ page 189, Braking capacity
and braking distance.

Alloy wheel rims
Every 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 im-
paired.
Always use an acid-free detergent for alloy wheel rims.
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 re-
paired immediately.
WARNING
● Never wash tyres with a cylindrical jet. Even at large spraying distan-
ces 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. Directly after washing, avoid sudden and sharp braking.
“Dry” the brakes by braking several times ⇒ page 189, Braking capacity
and braking distance.

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 re-
pair work and additional anti-corrosion work. 

205
Vehicle maintenance and cleaning
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.

Cleaning the engine compartment
Take special care when cleaning the engine compartment.
Anti-corrosion treatment
The engine compartment and the surface of the power unit are given anti-
corrosion treatment at the factory.
Good corrosion protection is particularly important in winter when the vehi-
cle is frequently driven on salted roads. To prevent the salt corroding the ve-
hicle, the entire engine compartment should be thoroughly cleaned before
and after winter.
Your Authorised Service Centre has got the necessary equipment to provide
the correct cleaning and preserving products. For this reason, we recom-
mend having this work performed by them.
The anti-corrosion protection is usually removed if the engine compartment
is cleaned with grease removing solutions, or if you have the engine
cleaned. On commissioning this work, ensure that all surfaces, seams,
joints and components in the engine compartment are given anti-corrosion
treatment.
WARNING
● When working in the engine compartment, always observe the safety
warnings ⇒ page 217.
● Before opening the bonnet, switch the engine off, apply the hand-
brake firmly and always remove the key from the ignition.
● Allow the engine to cool before you clean the engine compartment.
● Do not clean the vehicle underbody, wheel arches or wheel trims
without protecting your hands and arms. You may cut yourself on sharp-
edged metal parts. Failure to comply could result in injury.
● Moisture, ice and salt on the brakes may affect braking efficiency.
Risk of accident. Directly after washing, avoid sudden and sharp braking.
● Never touch the radiator fan. It is temperature-controlled and could
start automatically, even when the key is removed from the ignition!
For the sake of the environment
Fuel, grease and oil deposits could be removed when the engine is washed.
The polluted water must be cleaned in an oil separator. For this reason, en-
gine washing should be carried out only by a specialised workshop or a pet-
rol station. 
Vehicle interior maintenance Plastic parts and dash panel cleaning
– Use a clean, damp cloth to clean plastic parts and the dash
panel.
– If this does not provide satisfactory results, use a special sol-
vent-free plastic cleaning product. 
Safety FirstOperating InstructionsPractical TipsTechnical Specifications

206Vehicle maintenance and cleaning
WARNING
Never clean the dash panel and the airbag module surface with cleaners
containing solvents. Solvents cause the surface to become porous. If the
airbag triggered, plastic parts could become detached and cause inju-
ries.
CAUTION
Cleaning products which contain solvents will damage the material. 
Wooden trim cleaning*
– Clean the wooden trim with a water-moistened clean cloth.
– If this does not provide satisfactory results, use a gentle soap
solution.
CAUTION
Cleaning products which contain solvents will damage the material. 
Cleaning the radio and climate controls
To clean the radio and/or climate controls, use a soft damp cloth. For more
resistant dirt, a neutral soap solution may be used. Cloth seat covers and fabric trim cleaning
Cloth seat covers and fabric trim on the doors, headlining etc. can be
cleaned with a special interior cleaner or with dry foam and a soft brush.

Leather cleaning*
Normal cleaning
– Moisten a cotton or woollen cloth with water and wipe over the
leather surfaces.
Cleaning stubborn stains
– More stubborn dirt can be removed using a mild soap solution
(pure liquid soap; two tablespoons diluted in one litre of water)
and a cloth.
– Do not let the water soak through the leather or soak into the
seams.
– Then wipe off with a soft, dry cloth.
Leather maintenance
– The leather should be treated twice a year with a special leath-
er-care product, available in your Authorised Service Centre.
– Apply these products very sparingly.
– Then wipe off with a soft, dry cloth.
SEAT does everything possible to preserve the genuine qualities of this nat-
ural product. Due to the natural properties of the specially selected hides
employed, the finished leather has a certain sensitivity to grease and dirt, 
