When the vehicle is locked using the vehicle
●
key and the anti-theft alarm is turned on.
When the vehicle is locked, the alarm is trig-
gered when the electrical connection be-
tween the vehicle and the trailer is removed.
Always turn off the anti-theft alarm system
before connecting or disconnecting a trailer.
Otherwise, the tilt sensor may erroneously
activate the alarm.
Trailer with rear LED lights
For technical reasons, trailers fitted with rear
LED lights cannot be connected to the anti-
theft alarm system.
When the vehicle is locked, the alarm does
not trigger if the electrical connection with
the trailer is cut if it has rear light with light-
emitting diodes.
WARNING
Erroneous or unsuitable connection of
electric cables may supply energy to the
trailer causing an anomaly in the vehicle
electronics that could result in an accident
with serious consequences.
All work on the electrical system must be
●
carried out only by a specialised workshop.
Never connect the trailer's electric sys-
●
tem to the electrical connections of the
rear lights or any other power sources.

Driving
CAUTION
Do not leave the trailer connected to the
vehicle when parked; places on its support
wheel or its supports. For example, when
changing the load or a puncture, the vehi-
cle will be pushed up or down. The force
acting on the tow hitch and the trailer could
damage the vehicle or the trailer.
Note
In the event of a fault in the vehicle or
●
trailer electrical system or in the event of
problems with the anti-theft alarm system,
have the system checked by a specialised
workshop.
If the trailer accessories use energy from
●
the power socket when the engine is stop-
ped, the battery will be discharged.
For technical reasons, trailers fitted with
●
rear LED lights cannot be connected to the
anti-theft alarm system.
If the vehicle battery is running low, the
●
electrical connection with the trailer is au-
tomatically cut.
With the engine running, the electrical
●
equipment on the trailer will be supplied
with power.
Loading the trailer
Trailer weight / drawbar load
The trailer weight is the load that the vehicle
›››
can pull . The drawbar load is the verti-
cal weight of the tow hitch on the tow hitch
›››
ball page 309.
The figures for trailer weights and drawbar
load weights given on the data plate of the
tow hitch are for values of this model only.
The correct figures for your specific vehicle,
which may be lower than these figures for the
tow hitch, are given in the vehicle documen-
tation. The instructions in the official vehicle
documents take precedence.
For the sake of road safety, SEAT recom-
mends using the maximum allowed drawbar
load. The handling of the combined vehicle
and trailer will be poor if the drawbar load is
too low.
The drawbar load increases the weight on
the rear axle, reducing the vehicle carrying
capacity.
Gross combination weight
This figure refers to the combined weight of
the loaded vehicle and loaded trailer.
Loading the trailer
The combined vehicle and trailer must be
balanced. Use the maximum drawbar load
