Driving abroadObservationsTo drive abroad, the following must be taken into consideration:•
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.

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)

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.

Checking and refilling levels
202Checking and refilling levelsRefuellingThe fuel cap cover opens automatically with the central
locking system. The tank hold s approximately 55 litres.Unscrewing the tank cap
–Lift the lid.
– Unscrew the cap, turning it anti-clockwise.
Closing the tank cap
– Screw the tank cap to the right, until the point of feeling a “click”.
– Close the drawer. Make sure you hear it click into place. The tank
cap is secured with an anti-loss attachment
The tank flap is at the rear of the vehicle on the right.
If the automatic filler nozzle is operated correctly, it will switch itself off as
soon as the tank is “full”. Never attempt to fill beyond this point, as this will
fill the expansion chamber. Fuel may leak out if ambient conditions are warm.
The correct fuel grade for your vehicle is given on a sticker on the inside of the
fuel tank flap. where further notes on fuel can be found.
Releasing the fuel tank flap by hand
If the central locking system fails, the fuel tank flap can be opened manually
as follows:•
Open the tailgate
•
Remove the cover from the right side trim in the luggage compartment.
•
Insert a hand and pull the locking device back
•
Open the cap and take out the plug.
WARNING
•
Fuel is highly inflammable and can cause serious burns and other inju-
ries.
−Never smoke or use any naked flame when filling the fuel tank of the
vehicle, or a spare fuel canister, with fuel. This is an explosion hazard.
− Follow legal requirements for the use of spare fuel canisters.
− For safety reasons we do not recommend carrying a spare fuel
canister in the vehicle. The canister could be damaged in an accident
and leak.
•
If, in exceptional circumstances, you have to carry a spare fuel canister,
please observe the following points:

Te c h n i c a l D a t a
−
Never fill the spare fuel canister inside the vehicle or on it. An elec-
trostatic charge could build up during filling, causing the fuel fumes to
ignite. This may be fatally explosive. Always place the canister on the
ground to fill it.
− Insert the fuel nozzle into the mouth of the canister as far as
possible.
− If the spare fuel canister is made of metal, the filling nozzle must be
in contact with the canister during filling. This helps prevent an electro-
static charge building up.
− Never spill fuel in the vehicle or in the luggage compartment. Fuel
vapours are explosive. Danger of death.
Caution
•
Fuel spills should be removed from the paintwork immediately.
•
Never run the tank completely dry. An irregular fuel supply could cause
misfiring. As a result, unburnt fuel co uld enter the catalytic converter and
cause damage.For the sake of the environment
Do not try to put in more fuel after the automatic filler nozzle has switched off;
this may cause the fuel to overflow if it becomes warm.
PetrolPetrol types
The recommended fuel types are listed on a sticker inside the
fuel tank flap.Only unleaded petrol, corresponding to the 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
= “Regulation 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. Section “Technical Data”
Caution
•
Petrol that follows EN 228 may be mixed with small quantities of ethanol.
However, the so-called “bioethanol fuels” available at commercial establish-
ments with reference E50 or E85, which co ntain 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.
•
High engine speed and full throttle can damage the engine when using
petrol with an octane rating lower than the correct grade for the engine.For the sake of the environment
Just one full tank of leaded fuel would seriously impair the efficiency of the
catalytic converter.

204Petrol additives
Petrol additives improve the quality of the petrol.The quality of the petrol influences running behaviour, performance and
service life of the engine. For this reason, you should use good quality petrol
containing additives. These additives will help to prevent corrosion, keep the
fuel system clean and prevent deposits from building up in the engine.
If good quality petrol with additives is not available or engine problems occur,
the required additives must be added during refuelling.DieselDiesel*Diesel fuel must correspond to DIN EN 590 (EN = “European standard”). It
must have a cetane number (CN) of at least 51. The cetane number indicates
the ignition quality of the diesel fuel.
Notes on filling with fuel ⇒page 202.Biodiesel*The biodiesel fuel must comply with the DIN EN 14.214 (FAME) Standard.•
Biodiesel is a methylester obtained from rapeseed oil.
•
DIN is the German abbreviation for “Deutsches Institut für Normung e.V.”,
the German standards institute.
•
EN means E uropean Norm.
•
FAME is the English abbreviation for “ Fatty Acid Methyl Ester” Your Authorised Service Centre can also be consulted to know if the vehicle
has been prepared for biodiesel use.
Things to note about RME fuel (biodiesel)
•
The performance of a vehicle using biodiesel maybe somewhat reduced.
•
Fuel consumption of a vehicle usin
g biodiesel may be slightly higher.
•
RME fuel is resistant to the cold down to approx. -10°C.
•
At temperatures below -10°C, we recommend using winter diesel fuel.
•
Your vehicle is designed to be refuelled with up to a maximum of 7%
blended biodiesel in accordance with standard DIN 51628.Caution
•
RME fuel can damage the fuel system in vehicles which are not suitably
adjusted.
•
If you decide to use biodiesel in your vehicle, please use only RME fuel
which is DIN E 14,214 compliant.
•
If you use biodiesel that does not me et the required standard, the fuel
filter could become clogged.Note
•
In case of low exterior temperatures and a fuel biodiesel percentage of
higher than 50%, an increase in gas emission may occur during operation of
the independent heating.
•
The fuel filter may become clogged when fuel is changed to biodiesel. For
this reason, we recommend you that, when having run 300 or 400 km after a
fuel change, the fuel filter change must also be done. Also note the instruc-
tions in the Inspection and Maintenance plan.
•
If the vehicle is to remain parked for more than about two weeks, we
recommend filling the fuel tank with biodiesel and driving about 50 km in
order to avoid damage to the injection system.

Winter driving
Diesel can thicken in winter.Winter-grade diesel
When using “summer-grade diesel fuel”, difficulties may be experienced at
sub-zero temperatures because the fuel thickens due to wax separation.
Therefore, “winter-grade diesel fuel” is available in some countries during
the cold months. It can be used at temperatures as low as -22°C.
In countries with different climatic conditions the diesel fuel generally sold
has different temperature characteristics. Check with an Authorised Service
Centre or filling stations in the country concerned regarding the type of diesel
fuels available.
Filter pre-heater
Your vehicle is fitted with a fuel filter pre-heater, making it well equipped for
operation in winter. This ensures that the fuel system remains operational to
approx. -24°C, provided you use winter-grade diesel which is safe to -15°C.
However, if the fuel has waxed to such an extent that the engine will not start
at temperatures of under -24°C, simply place the vehicle in a warm place for
a while.
Caution
Do not mix fuel additives (“thinners”, or similar additives) with diesel fuel.
Working in the engine compartmentSafety instructions on working in the engine compartment
Any work carried out in the engine compartment or on the
engine must be carried out cautiously.Before starting any work on the engine or in the engine compart-
ment:
1. Switch off the engine and remove the key from the ignition.
2. Apply the handbrake.
3. Move the gear stick to neutral or the selector lever to position P.
4. Wait for the engine to cool down.
5. Keep children away from the vehicle.
6. Raise the bonnet ⇒page 207.You should not do any work in the engine compartment unless you know
exactly how to carry out the jobs and have the correct tools! Have the work
carried out by a qualified workshop if you are uncertain.
All service fluids and consumables, e.g. coolant, engine oil, spark plugs and
batteries, are being constantly developed. SEAT provides a constant flow of
information to the Authorised Service Centres concerning modifications. For
this reason, we recommend you to have service fluids and consumables
replaced by an Authorised Service Centre. Please observe the relevant
instructions ⇒page 200. The engine compartment of any motor vehicle is a
hazardous area ⇒ .
