The towing bracket must meet certain technical requirements.Your vehicle 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 for 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 at an Authorised Service.
If a towing bracket is to be fitted after the vehicle is purchased, this must be
done according to the instructions of the towing bracket manufacturer
⇒ page 212.
WARNING
If a towing bracket is retrofitted, the installation should be carried out by a
qualified workshop.•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 301.Trailer weight
Never exceed the maximum permitted trailer weight.
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
1000 m 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 must be reduced by about 10% for every
subsequent 1000 m (or part thereof). This figure refers to the combined
weight of the (loaded) vehicle and (loaded) trailer.
The figures for the drawbar load 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 294. Also refer to
⇒ page 301.
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.

Trailer towing
204Where 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.
Tyre pressure
Check the tyre pressures on your vehicle, 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 mirrors 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 120.
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 the vehicle serviced
between services.
Notes on towing
Towing a trailer involves additional 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 slow to allow for
the unbalanced weight distribution.
Speed
The stability of the vehicle and trailer is reduced with increasing speed. There-
fore, it is advisable not to drive at the maximum permissible speed in unfa-
vourable 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 stabilise the trailer by accelerating.
Anticipate hazards and brake in good time. If towing a trailer with an inertia
brake , first brake gently and then harder. 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 weight.
They can be purchased and installed at a Technical Service.
Reheating
When climbing long hills in hot weather with 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 lamp
v in the instrument panel should start
flashing, stop the vehicle and let the engine cool down by running it at idling
speed for a few minutes.

Equipment and accessories
Before mounting equipment and accessories (e.g. bicycle
rack) please observe the following notes.The equipment/accessories mounted must not protrude more than 700 mm
from the ball joint .
The total weight (mounted equipment plus the load) must not exceed 75 kg.
The maximum load depends on where the centre of gravity lies.
The maximum weight decreases as the distance between the centre of gravity
and the ball joint increases.
The following limits apply:
If the distance is 300 mm, the total weight (incl. the equipment mounted)
must not exceed 75 kg.
If the distance is 600 mm, the total weight (incl. the equipment mounted)
must not exceed 35 kg. Only bicycle racks for
a maximum of three bicycles may be used.
Equipment and accessories mounted on the towing bracket
SEAT recommends that you only mount equipment (e.g. bicycle rack) on the
towing bracket which has been officially approved.. If you wish to attach other
equipment please make sure that it has been approved by the manufacturer
for use on the towing bracket. If you mount unsuitable equipment, this can
cause damage to the towing bracket. In an extreme case, damage to the
towing bracket could cause it to break ⇒.
WARNING
•If you wish to mount equipment which has not been approved by SEAT,
please ensure that it is suitable for use on SEAT vehicles.•The use of unsuitable accessories ca n result in severe damage to the
towing bracket, which could break while pulling a trailer. Risk of accident.•Never use tools of any kind when fitting and removing the ball joint.
This would damage the locking device, no longer guaranteeing the correct
working order of the bracket. This could lead to an accident.
