Avoid driving at high speed
We advise you not to drive at the top speed permitted by the vehicle. Fuel
consumption, exhaust emissions and noise levels all increase very rapidly at
higher speeds. Driving at moderate speeds will help to save fuel.
Avoid idling
It is worthwhile switching off the engine when waiting in a traffic jam, at level
crossings or at traffic lights with a long red phase. The fuel saved after only
30 - 40 seconds is greater than the amount of fuel needed to restart the
engine.
The engine takes a very long time to wa
rm up when it is running at idling
speed. Mechanical wear and pollutant emissions are also especially high
during this initial warm-up phase. It is therefore best to drive off immediately
after starting the engine. Avoid running the engine at high speed.
Periodic maintenance
Periodic maintenance work guarantees that, before beginning a journey, you
will not consume more than the required amount of fuel. A well-serviced
engine gives you the benefit of improved fuel efficiency as well as maximum
reliability and an enhanced resale value.
A badly serviced engine can consume up to 10% more fuel than necessary.
Avoid short journeys
To reduce the consumption and emission of polluting gases, the engine and
the exhaust filtration systems should reach the optimum service tempera-
ture .
With the engine cold, fuel consumption is proportionally higher. The engine
does not warm up and fuel consumption does not regularise until having
driven some four kilometres. This is the reason why we recommend avoiding
short trips wherever possible.
Maintain the correct tyre pressures
Bear in mind that keeping the tyres at an adequate pressure saves fuel. If the
tyre pressures are just 1 bar too low, this can put the fuel consumption up by as much as 5 %. Due to the greater rolling resistance, under-inflation also
increases tyre wear
and impairs handling.
The tyre pressures should always be checked when the tyres are cold.
Do not use winter tyres all through the year: they will increase fuel consump-
tion by up to 10 %.
Avoid unnecessary weight
Every kilo of extra weight will put up the fuel consumption, so it is worth
checking the luggage compartment occasionally to make sure that no unnec-
essary loads are being transported.
A roof carrier is often left in place for the sake of convenience, even when it is
no longer needed. At a speed of 100- 120 km/h your car will use about 12%
more fuel as a result of the extra wind resistance caused by the roof carrier
even when it is not in use.
Saving electrical energy
The engine activates the alternator, whic h produces electricity. With the need
for electricity, fuel consumption is also increased. Because of this, always
turn off electrical equipme nt when you do not need them. Examples of equip-
ment that use a lot of electricity are: the fan at high speeds, the rear window
heating or the seat heaters*.

For vehicles fitted with a catalytic converter ensure that unleaded petrol is
available for the journey. See the chapter “Refuelling”. Automobile organisa-
tions will have information about service station networks selling unleaded
fuel.
•
In some countries it is possible that a vehicle model is sold under condi-
tions where some spare parts are not available or that the Authorised Service
Centres may only carry out limited repairs.
SEAT importers and distributors will gladly provide information about the
technical preparation of your vehicle and also about necessary maintenance
and repair possibilities.
Adhesive strips for headlightsIf you have to drive a right-hand drive vehicle in a left-hand drive country, or
vice versa, the asymmetric dipped beam headlights will dazzle oncoming
traffic.
To prevent dazzling, you must apply stickers to certain parts of the headlight
lenses. Further information is available in your Authorised Service Centre.
In vehicles with self-directing headlights, the rotation system must previ-
ously be disconnected. To do this, please go to a specialist workshop.

Trailer towing187
Safety First
Operating instructions
Practical tips
Te c h n i c a l D a t a
Trailer towingInstructions to followYour 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. For the after-market fitting of a trailer towing bracket see
⇒ page 189.
Connectors
Your vehicle is fitted with a 12-pin co nnector 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 / draw bar loading
Never exceed the authorised towing limit. 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
1,000 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 co mbination must be reduced by 10% for
every further 1,000 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 draw bar
weight on the ball joint of the towing bracket, but do not exceed the specified
limit. The figures for
trailer weights and draw bar weights 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 registration documents ⇒Section
“Technical 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 ca se, 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
190If a towing bracket is to be fitted after the vehicle is purchased, this must be
completed according to the instructions of the towing bracket manufacturer.
The attachment points for the towing bracket are on the lower part of the
vehicle.
The distance between the centre of the ball coupling and the ground should
never be lower than the indicated value, even with a fully loaded vehicle and
including the maximum resting weight.
Elevation values for securing the towing bracket:
65 mm (minimum)
350 mm to 420 mm (fully laden vehicle)
357 mm
569 mm
875 mm
1,040 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.
•
Submit to the legal requirements in your country (e.g. the fitting of a sepa-
rate warning lamp).
•
Certain vehicle components, e.g. the rear bumper, must be removed and
reinstalled. The towing bracket securin g bolts must be tightened using a
torque wrench, and an electrical socket must be connected to the vehicle's
electrical system. The above-mentione d require specialized 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
Towing brackets should be fitted by specialists.
•
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 electrical socket is incorrectly installed, this could cause damage to
the vehicle's electrical system.Note
For the sports model (FR, Cupra...), fi tting of a trailer bracket is not recom-
mended due to the design of the bumpers.

Practical tips
Te c h n i c a l D a t a
Cleaning and caring for your vehicleGeneral notesRegular washing and care help maintain the value of your
vehicle.Your 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 corr osion or paint defects.
The best way to protect the car against environmental contaminants is to
wash and wax it frequently. The longer substances such as insects 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. For this, they must always be kept
closed in their original container. Keep them out of the reach of children.
Failure to comply could result in poisoning.
•
Always read and observe the instructions and warnings on the package
before using car care products. Improper use could damage your health or your 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 your 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 clea ning 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 leftovers of the car care products should not be disposed of with ordi-
nary household waste. Observe the disposal information on the package.WARNING (continued)

Cleaning and caring for your vehicle
194A good quality hard wax product is available from your Authorised Service
Centre.
Regular wax applications help to protects the paintwork from environmental
contaminants. ⇒page 191. It also protects against minor scratches.
Even if a wax solution is used regularly in the car washing tunnel, it is advis-
able 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. P olishing products can be purchased in
your Authorised Service Centre.
The car must be waxed after polishing if the polish used does not contain wax
compounds to seal the paint ⇒page 193, “Vehicle paint maintenance
requirements”.
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 snow 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.

Practical tips
Te c h n i c a l D a t a
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. If a window cleanser
, specifically for removing wax, is added
to the windscreen washer fluid prevents wiper blades from juddering. Wax
deposits 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 elements
inside the window.
Cleaning windscreen wiper bladesClean wiper blades are essential to provide clear vision.
1. Use a soft cloth to remove dust and dirt from the windscreen wiper blades.
2. Use window cleanser to clean the windscreen wiper blades. Use a sponge or a cloth to remove stubborn stains.
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 strips on the doors, windows, bonnet and rear lid will remain pliable and
last longer if they are treated with a suitable care product (for example sili-
cone 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.

Underbody sealant
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
ckeck 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! Fire hazard.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 car 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.
Your Authorised Service Centre 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 remo
ving solutions, or if you have the engine cleaned.
On commissioning theis work, ensure that all surfaces, seams, joints and
components in the engine compartment are given anti-corrosion treatment.
WARNING
•
When working in the engine compartm ent, always observe the safety
warnings ⇒page 205.
•
Before opening the bonnet, switch the engine off, apply the parking
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 without protecting
your hands and arms. You may cut your self 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 be carried out on ly by a qualified workshop or a petrol
station.
