WARNING
If the cables are improperly or incorrectly
connected, it may lead to an excessive
amount of current supplied to the trailer,
which can cause abnormalities in the entire
vehicle electronic system, as well as acci-
dents and serious injuries.
Ensure that any repairs that need to be
●
carried out on the electrical system are
carried out by a specialised workshop.
Never connect the trailer's electric sys-
●
tem directly to the electrical connections
of the tail lights or any other power sour-
ces.
WARNING
Contact between the pins of the trailer
power socket can cause short circuits,
overloading of the electrical system or fail-
ure of the lighting system, and consequent-
ly can cause accidents and serious injuries.
Never connect the pins of the trailer pow-
●
er socket to each other.
Make sure any work on bent pins is car-
●
ried out by a specialised workshop.
CAUTION
Do not leave the trailer connected to the
vehicle when parked; place it on its support
wheel or its supports. If the vehicle rises or
falls due, for example, to a variation of the
load or a burst tyre, increased pressure will

be placed on the towing bracket and the
trailer, and both the vehicle and the trailer
can be damaged.
Note
In case of anomalies in the electrical sys-
●
tems of the vehicle or trailer, as well as in
the anti-theft alarm system, have them in-
spected by a specialised workshop.
If the trailer accessories consume energy
●
through the power socket to the trailer and
the engine is turned off, the battery will dis-
charge.
If the vehicle battery is running low, the
●
electrical connection with the trailer will be
automatically cut.
Trailer loading
Technically permissible maximum trailer
weight and vertical load on the coupling
device
The technically permissible maximum trailer
weight is the weight that the vehicle can tow
›››
. The vertical load on the coupling is ex-
erted vertically from above on the hook of the
towing bracket.
The information on the maximum trailer
weight and vertical load on the coupling de-
vice contained in the type plate of the towing
bracket are experimental values only. The
correct figures for your specific model, which
may be lower than these figures, are given in
the vehicle documentation. The information in
the vehicle documentation takes precedence
at all times.
To promote safety while driving, SEAT recom-
mends making the most of the maximum ver-
tical load technically permissible on the
›››
coupling device page 332. An insufficient
vertical load has a negative influence on the
behaviour of both the vehicle and trailer.
The vertical load increases the weight on the
rear axle, reducing the vehicle's carrying ca-
pacity.
Gross combination weight of the towing
vehicle and trailer
The gross combination weight is the actual
weight of the loaded vehicle plus the actual
weight of the loaded trailer.
In some countries trailers are classified into
distinct categories. SEAT recommends ob-
taining information from a specialised work-
shop regarding which type of trailer is most
suitable for your vehicle.
Trailer loading
The weight of the towing vehicle and trailer
must be balanced. In order to do this, the
load must be as close as possible to the max-
imum vertical load technically permissible on
the coupling point, and it must be evenly
