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.

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.
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 ordinar y
household waste. Observe the disposal information on the package.WARNING (continued)

208Steel 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 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. Directly after washing, avoid sudden and sharp braking. Dry the
brakes by braking several times ⇒page 193, “Braking capacity and
braking distance”.
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.

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 vehicle
is frequently driven on salted roads. To prevent the salt corroding the vehicle,
the entire engine compartment should be thoroughly cleaned before and
after winter.
Yo u r A u t h o r i s e d S e r v i ce Ce n t re has got the necessary equipment to provide
the correct cleaning and preserving products. For this reason, we recommend
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 221.•Before opening the bonnet, switch the engine off, apply the handbrake
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,
engine washing should only be carried out at a specialised workshop or an
adequate petrol station.Vehicle interior maintenancePlastic 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 solvent-free plastic cleaning product.
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 injuries.
Caution
Cleaning products which contain solvents will damage the material.

The LPG tank ⇒fig. 140 in the spare wheel well has a capacity of 39 litres. If
the outside temperatures are very low, it may not be possible to completely
fill the LPG tank.
Pump attachments
There are a variety of types of LPG pump, and the methods of use may vary.
Therefore, let the pump operator fill the tank when refuelling for the first time
or fill from another pump.
Noises when refuelling with LPG
When refuelling with LPG, noises may be heard. These noises are insignifi-
cant.
WARNING
Failure to refuel or handle LPG in the correct way could result in a fire, cause
an explosion or lead to injuries.•LPG is a highly explosive and inflammable substance. It may cause
severe burns and other injury.•Switch off the engine before refuelling.•Always disconnect mobile phones and any other radiophony appli-
ances, as electromagnetic waves may produce sparks and cause a fire.•Do not remain in the vehicle while refuelling. If it is absolutely neces-
sary to enter the vehicle, close the door and touch a metal surface before
touching the attachment again. This will prevent the generation of static
electricity and any possible fires while refuelling.
•Small quantities of LPG may leak out after refuelling. If LPG comes into
contact with skin, there is a risk of freezing.•Do not smoke and always keep bare flames away from the tank during
refuelling. Failure to do so may lead to an explosion.

The safety of the LPG system guarantees operation without risk. The following
safety measures have been adopted:
•The LPG tank has a solenoid valve which closes automatically when the
engine is switched off (ignition off) or when running on petrol.•A solenoid type main valve disconnects the supply of gas to the engine
compartment when the engine is switched off or running on petrol.•A safety valve in the LPG tank with pipes to the outside prevents the gas
from entering the vehicle interior.•All anchorage points and materials have been designed to ensure the
maximum possible levels of safety.
The condition of the LPG system should be checked regularly to guarantee
safe driving conditions ⇒ . These checks are included in the Maintenance
Programme.WARNING
•If there is a smell of gas or a suspected leak, stop the vehicle immedi-
ately and switch off the ignition. Open the doors to ventilate the vehicle. Do
not carry on driving! Take the vehicle to a specialised workshop and have
the fault repaired.•Immediately extinguish any cigarettes and remove from the vehicle any
objects which might produce a spark or cause a fire, and switch off imme-
diately if gas is smelt or a leak is detected.•LGP tanks are subject to pressure and must be checked regularly. The
owner of the vehicle must check that these services are performed
correctly.•When parking the vehicle in a closed area (for example in a garage),
make sure that there is adequate ventilation, either natural or mechanical,
to neutralise the LPG in the event of a leak.
Note
For any fault in the LGP system, please refer to the SEAT web page, which lists
the workshops authorised to repair these faults.PetrolPetrol types
The recommended fuel types are listed on a sticker inside the
fuel tank flap.Only unleaded petrol conforming to standard DIN EN 228 may be used for
vehicles with catalytic converters (EN = “European Standard”).
Fuel types are differentiated by the octane rating, e.g: 91, 95, 98 RON (RON
= “Research Octane Number”, unit for determining the knock resistance of
petrol). You may use petrol with a higher octane number than the one recom-
mended for your engine. However, this has no advantage in terms of fuel
consumption and engine power.
The correct fuel type for your vehicle is given in the technical table for the
engine, in the Technical Data section.
Caution
•Petrol with standard EN 228 may be mixed with small quantities of
ethanol. However, the so-called “bioethanol fuels” available at commercial
establishments with reference E50 or E85, which contain a high percentage
of ethanol, may not be used, as they will damage the fuel system.•Even one tankful of leaded fuel would permanently impair the efficiency
of the catalytic converter.
