Trailer towing
186Trailer towingTrailer towingTechnical requirements
The towing bracket must meet certain technical requirements.Your car is intended mainly for transporting passengers and luggage.
However, if suitably equipped, it can also be used to tow a trailer or caravan.
If your vehicle has been factory-supplied with a towing bracket, all of the
necessary technical and legal aspects fo r trailing towing have been taking
into account during manufacturing.
Your vehicle is fitted with a 13-pole socket for the electrical connection
between the trailer and the vehicle. If the trailer has a 7-pole connector you
can use an adapter cable. This can be purchased from any SEAT Dealer.
If a towing bracket is to be fitted after the car is purchased, this must be done
according to the instructions of the towing bracket manufacturer
⇒ page 195.
WARNING
If a towing bracket is retrofitted, the installation should be carried out by a
specialist garage.•
Particularly in high outdoor temperatures, it is not possible to drive up
long steep gradients without a suitable cooling system. The engine would
heat up.
•
Incorrect installation can result in a safety risk!
Notes on towing
There are a number of points which need to be checked before
towing a trailer or caravan.– Observe the maximum permitted trailer weights ⇒page 282.Trailer weights
Never exceed the maximum permitted trailer weights.
If you do not load the trailer up to the maximum permitted trailer weight, you
can then climb correspondingly steeper gradients.
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 car and trailer must be reduced by about 10% for every subse-
quent 1000 m (or part thereof) . This figure refers to the combined weight of
the (loaded) vehicle and (loaded) trailer.
The figures for the draw bar weight that appear on the identification 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 and on ⇒page 274. Also
refer to ⇒ page 282.
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.

Operating instructions
Practical tips
Te c h n i c a l D a t a
Where 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.
Tyre pressure
Check the tyre pressures on your car, and adjust for “full load” conditions
(refer to the sticker listing the tyre pressures on the door pillar). It may also be
necessary to adjust the tyre pressures on the trailer according to the recom-
mendations of the trailer manufacturer.
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. The two exterior mi rrors should be fitted on folding arms. Adjust the
mirrors to give sufficient rear vision.
Headlights
Before starting a journey, check the headlight beam settings with the trailer
hitched up. If necessary, alter the height of the headlight beams by means of
the headlight range control. See ⇒page 116.
Power supply
When you remove the ignition key, the power supply to the trailer is inter-
rupted.
Removable ball joint coupling
Vehicles with a factory-fitted towing bracket are equipped with a removable
ball joint coupling. This is stored in the spare wheel well in the luggage
compartment together with the necessary fitting instructions.
Note
If you frequently tow, we recommend you also have vehicle serviced between
services.
Notes on towing
Towing a trailer involves additi onal attention by the driver.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 we ight distribution.
Speed
The stability of the car and trailer is reduced with increasing speed. Therefore,
it is advisable not to drive at the maximum permissible speed in an unfavour-
able road, weather or wind conditions. This especially applies when driving
downhill.
You should always reduce speed immediately if the trailer shows the slightest
sign of swaying. Never try to stop the “snaking” by increasing speed.
Anticipate hazards and brake in good time. If towing a trailer with an inertia
brake , first brake gently and then more severely. This will prevent brake
tapping by the trailer wheels when they lock. 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.
Swaying and pitching can be reduced by stabiliser aids. We recommend
having stabiliser aids installed when towing trailers with a high trailer load.
They can be purchased and installed at a Dealer.
Reheating
When climbing long hills in hot weather wi th the engine running fast in low
gear, you should keep an eye on the coolant temperature gauge ⇒page 60.
Reduce speed immediately if the needle moves to the right end of the scale.
If the temperature warning light
 in the instrument cluster should start
flashing, stop the car and let the engine cool down by running it at idling
speed for a few minutes.

210PetrolPetrol 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 high er 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 mixe d with small quantities of ethanol.
However, the so-called “bioethanol fuels” available at commercial establish-
ments, e.g. 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 woul d 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.
Petrol 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 re ason, 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 refuelling ⇒page 208.Biodiesel*The biodiesel fuel must comply wi th the DIN EN 14.214 (FAME) Standard.•
Biodiesel is a methylester obtained from rapeseed oil.
•
DIN is the German abbreviation for “ Deutsches Institut für N ormung e.V.”,
the German standards institute.
•
EN means European Norm.
•
FAME is the English abbreviation for “F atty 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 using biodiesel may be slightly higher.
•
RME fuel is resistant to the cold down to approx. -10°C.
•
At temperatures below -10°C, we re
commend using winter diesel fuel.
•
Your vehicle is designed to be refuelled with up to a maximum of 7%
blended biodiesel.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 meet 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 countr y 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-g rade 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.

Oil propertiesViscosity
The viscosity class of the oil is selected according to the diagram.
When the ambient temperature falls outside the limits of the scale for a short
period, an oil change is not required.
Mono-grade oil
Single grade oils are generally not suitable for all year round use, due to
ranges of viscosity

Caution
•
The oil level must never be above area . This could damage the cata-
lytic converter or the engine. Contact a specialist garage to drain the engine
oil if necessary.
•
No additives should be used with engine oil. Any damage caused by the
use of such additives would not be covered by the factory warranty.For the sake of the environment
•
Oil must not be disposed of into the drains or onto the ground.
•
Always observe legal requirements when disposing of empty oil
canisters.
Cooling systemLiquid coolant
The purpose of the liquid coolant is to carry heat away from
the engine. The correct amount of antifreeze is decisive in
preventing the cooling system from freezing in winter.The your vehicle's engine cooling system is filled for life at the factory, so no
coolant needs to be changed. The liquid coolant consists of a mixture of water
and anti-freeze G12++. This is a glycol-b ased antifreeze with anti-corrosion
additives.
Liquid coolant additive
The amount of antifreeze required depends on the temperatures to be
expected in the winter season. If the antifreeze concentration is too low the
coolant can freeze, resulting in failure of the cooling system and heater. The cooling system is filled at the fact
ory with the correct amount of anti-
freeze for the country concerned.
In most cases, the mixture consists of 60% water and 40% anti-freeze. This
mixture gives the required anti-freeze protection at temperatures down to
-25°C and particularly protects the metal parts of the cooling system against
corrosion. It also prevents scaling and significantly raises the boiling point of
the liquid coolant.
Countries with warm climate
The liquid coolant concentration must not be reduced by adding plain water,
even in the summer or in warm climates. The concentration of the anti-freeze
must always be at least 40%.
Countries with cold climate
If greater frost protection is required in very cold climates, the proportion of
the anti-freeze G12++ can be increased. A concentration of 60% offers anti-
freeze protection of temperatures down to approx. -40°C. However,the
concentration of anti-freeze must not exceed 60%, as the anti-freeze protec-
tion would then drop and the performance of the coolant system would suffer.
Vehicles for countries with cold clima tes (e.g. Sweden, Norway and Finland)
have factory-filled anti-freeze protection for temperatures down to -35°C. In
these countries, the concentration of anti-freeze should always be at least
50%.
Caution
•
It is advisable to have the cooling system checked before the winter
season to make sure that the antifreeze concentration is adequate for the
conditions to be expected. This applies particularly if you intend to take the
car into a colder climate zone. If necessary, have the antifreeze concentration
increased to 50 - 60% as required.
•
Use only anti-freeze G12++ , an additive meeting the “TL-VW 774G” spec-
ification. Other anti-freezes may give considerably inferior corrosion protec-

Checking and refilling levels
218tion. The damage caused by the use of these anti-freezes may lead to a loss
of liquid coolant, causing serious damage to the engine.•
The anti-freeze G12++ can be mixed on ly with anti-freeze additives G11,
G12 and G12+.
Checking the liquid coolant level
The liquid coolant level can be checked at a glance.– Switch the ignition off.
– Check the coolant level on liquid coolant expansion tank ⇒fig. 167. When the engine is cold, it should be between the
“min” and “max” marks. When the engine is hot, it may be
slightly above the “max” mark.Its location is shown in the correspon ding general overview of the engine
compartment. The liquid coolant level should be checked with the engine switched off.
The liquid coolant level is monitored
by a warning lamp in the instrument
panel ⇒ page 77. However, we recommend that it should be checked occa-
sionally.
Liquid coolant losses
Any loss of liquid coolant normally indicates a leak in the cooling system. In
this case the cooling system should be inspected by a specialist garage
without delay. It is not sufficient merely to top up the liquid coolant.
If there are no leaks in the system, a loss of liquid coolant can only occur if
the coolant boils and is forced out of the system as a result of overheating.
Caution
Radiator sealants must not be added to the liquid coolant. Such additives
could seriously impair the function of the cooling system.Topping up the liquid coolant
Be careful when topping up with liquid coolant.– Switch the engine off.
– Wait for the engine to cool down.
– Cover the cap on the expansion tank ⇒fig. 167 with a cloth, an d
carefully unscrew the cap anti-clockwise ⇒ .
– Add liquid coolant.
– Screw on the cap tightly.
