Towing bracket device*
T r
ailer mode
Introduction Take into account country-specific regula-
tions about driving with a tr
ail

er and the use
of a towing bracket.
The vehicle has been developed primarily for
carrying people, although it can also be used
to tow a trailer if fitted with the corresponding
technical equipment. This additional load has
an effect on the useful life, fuel consumption
and vehicle performance and in some cases
can reduce the service intervals.
Driving with a trailer requires more force from
the vehicle, and thus more concentration
from the driver.
In winter, winter tyres should be fitted on both
the vehicle and the trailer.
Maximum vertical load technically permit-
ted on the coupling device
The maximum technical permitted vertical
load of the trailer's towing bracket on the
hook of the tow-bar is 80 kg.
Vehicles with the Start-Stop system
If the vehicle has a factory-fitted towing
bracket or one that is retrofitted by SEAT, the Start-Stop system operates as normal. No
special char
act

eristics need to be taken into
account.
If the system does not recognise the trailer or
the trailer bracket has not been retrofitted by
SEAT, the Start-Stop system must be discon-
nected by pressing the corresponding button
in the lower part of the centre console before
driving with the trailer, and it should remain
off for the rest of the journey ››› .
V ehicl

es with driving profile selection
If you are going to be towing a trailer, the use
of the Eco driving profile is not recommen-
ded. You are advised to select another of the
available driving profiles before beginning to
drive with a trailer.
Trailer weight/drawbar load
Never exceed the authorised trailer weight. 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 1000 m above
sea level. Since higher altitude decreases en-
gine performance and the ability to climb
slopes, the tow load decreases proportional-
ly. The weight of the vehicle and trailer com-
bination must be reduced by 10% for every
1000 m of altitude. When possible, operate
the trailer with the maximum authorised drawbar load on the ball joint of the to

wing
bracket, but do not exceed the specified lim-
it. WARNING
Never use the trailer to transport people,
since it w oul

d put their life in danger and is
also prohibited. WARNING
Undue use of the towing bracket may
cause injury and accidents.

WARNING
Driving with a trailer and transporting
heavy or l ar
ge objects can affect driving
properties and even cause an accident.

Driving
Trailer brakes
If the tr ail
er has its own brake system, please
take the relevant legal requirements into ac-
count. Never connect the trailer's brake sys-
tem to the vehicle's brake system.
Tow cable
Always use a cable between the vehicle and
the trailer ››› page 300
.
Trailer tail lights
The trailer's rear lights should comply with
the statutory safety regulations ››› page 300
.
Never connect the trailer's rear lights directly
to the vehicle's electric system. If you are not
sure that the trailer's electrical connection is
correct, have it checked by a specialised
workshop. SEAT recommends visiting a SEAT
dealership for this.
Exterior mirrors
If you cannot see the area behind the trailer
with the exterior mirrors of the towing vehicle,
additional mirrors will have to be installed in
accordance with the regulations of the coun-
try in question. The exterior mirrors should be
adjusted before you start driving and must
provide a sufficient field of vision at the rear. WARNING
If the towing bracket is wrongly fitted or is
not the right one , the tr

ailer could become detached from the vehicle and cause seri-
ous injury.
CAUTION

Towing bracket device*
This powers, for example, the trailer's interior
lighting. El ectrical de
vices such as a fridge in
a caravan only receive electrical power if the
engine is running (through pin 10).
To avoid overloading the electrical system,
you cannot connect the ground wires of pin
3 , pin 11 or pin 13 to each other.
If the trailer has a 7-contact connector, you
will need to use an adapter cable. In this case
the function corresponding to pin 10 will not
be available.
Tow cable
The tow rope must always be securely fixed
to the towing vehicle and loose enough so
that the vehicle can handle turns smoothly.
However, make sure that the cable does not
rub on the ground while driving.
Trailer tail lights
Always check the trailer's rear lights to ensure
they are working correctly and that they
comply with the relevant safety regulations. If
you connect the trailer to the factory-moun-
ted system, when you turn on the rear fog
lamp, the fog lamp of the towing vehicle will
turn off to turn on the trailer fog lamp.
Include in the anti-theft alarm
The trailer is included in the anti-theft system
if the following conditions are met:

Indications about the technical data
Empty weight, total weight, axle loads
The empt y w
eight of the vehicle with driver
(75 kg) was calculated according to the (EU)
1230/2012 standard. Optional equipment can
increase the empty weight, which means that
the possible useful load decreases propor-
tionally.
Trailer weight
The maximum permitted drawbar load on the
ball head of the towing bracket is 80 kg. WARNING
The values indicated for the maximum per-
mitt ed w

eights must not be exceeded.
There is a risk of accident and damage! 373
