13Earth, pin 9 Electrical socket for trailer
The v
ehic

le is fitted with a 13-pole power
socket for the electrical connection between
the trailer and the vehicle. If the system de-
tects that a trailer has been connected elec-
trically, the electrical equipment on the trailer
will receive voltage through this connection.
Pin 9 has a permanent live. This powers, for
example, the trailer's interior lighting. Pin 10
is only powered when the engine is running.
The charge wire (pin 10) charges, for exam-
ple, a caravan battery.
Pin 9 and 10 should not be connected to
each other to avoid discharging or damaging
the vehicle's battery.
The earth wires, pin 3, pin 11 and pin 13,
should never be connected to each other to
avoid overloading the electrical system.
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. Trailer maximum electricity consumption

Note
● If the r e

ar lights of the trailer are not cor-
rectly connected, the vehicle electronics may
be damaged.
● If the trailer absorbs excessive electric cur-
rent, the v
ehicle electronics may be dam-
aged.
● Never connect the trailer's electric system

● Never u se the s

afety lug to tow!
● Adjust your speed to suit the road and traf-
fic condition
s.
● All work on the electrical system must be
carried out on
ly by specialised workshops.
● Never connect the trailer's electric system
to the electric
al connections of the rear lights
or any other power sources.
● After hooking up the trailer and connecting
the socket, c
heck that all the trailer's rear
lights are working properly. Note
● If ther e i

s any fault in the trailer's lighting,
check the fuses in the instrument panel fuse
box ›››

● The contact between the retainer cable and
the safety
lug may give rise to mechanical
wear in the lug's surface protection. This
wear will not prevent the safety lug from op-
erating properly or cause any fault and is ex-
cluded from the warranty.

tween vehicle and trailer is interrupted.
Always turn off the anti-theft alarm system
before connecting or disconnecting a trailer
››› page 132.
Conditions for the integration of a trailer in
the anti-theft alarm system.
● The vehicle is factory-equipped with an an-
ti-theft al

arm system and a towing bracket
device.
● The trailer is connected electrically to the
tow
ing vehicle by the trailer connector.
● The electrical system of the vehicle and the
trail
er are prepared for operation.
● The vehicle is locked with the ignition key
and the anti-theft al
arm system is activated.CAUTION
For technical reasons, trailers fitted with rear
LED lights ar

e not integrated in the anti-theft
alarm system. Driving tips
Driving with a trailer always requires extra
c
ar e. W

eight distribution
The weight di
stribution of a loaded trailer
with an unladen vehicle is very unfavourable.
However, if this cannot be avoided, drive ex-
tra slowly to allow for the unbalanced weight
distribution.
Speed
The stability of the vehicle and trailer is re-
duced with increasing speed. For this reason,
it is advisable not to drive at the maximum
permissible speed in an unfavourable road,
weather or wind conditions. This applies es-
pecially when driving downhill.
You should always reduce speed immediately
if the trailer shows the slightest sign of snak-
ing. Never try to stop the “snaking” by in-
creasing speed.
Always brake in due course. If the trailer has
an overrun brake, apply the brakes gently at
first and then, firmly. This will prevent the
jerking that can be caused by locking of trail-
er wheels. Select a low gear in due course
before going down a steep downhill. This en-
ables you to use the engine braking to slow
down the vehicle.
Reheating
At very high temperatures and during pro-
longed slopes, driving in a low gear and high
engine speed, always monitor the coolant
temperature gauge ››› page 116. Electronic stability control*
The ESC* sys
tem helps to stabilise the trailer
in case of skidding or rocking.

Operation
If a towing bracket is to be fitted after the ve-
hic l
e i
s purchased, this must be completed
according to the instructions of the towing
bracket manufacturer.
The attachment points for the towing bracket A are on the lower part of the vehicle.
The di s
t

ance between the centre of the ball
coupling and the ground should never be
lower than the indicated value, even with a
fully loaded vehicle and including the maxi-
mum drawbar load.

F338 mm Fitting a towing bracket
●
Driving with a trailer involves an extra effort
f or the
v

ehicle. Therefore, before fitting a
towing bracket, please contact a Technical
Service to check whether your cooling system
needs modification.
● The legal requirements in your country
must
be observed (e.g. the fitting of a sepa-
rate control lamp). ●
Cert
ain vehicle components, e.g. the rear
bumper, must be removed and reinstalled.
The towing bracket securing bolts must be
tightened using a torque wrench, and a pow-
er socket must be connected to the vehicle
electrical system. This requires specialised
knowledge and tools.
● Figures in the illustration show the eleva-
tion value and the att
achment points which
must be considered if you are retrofitting a
towing bracket. WARNING
The towing brackets should be fitted at a spe-
ci a

lised workshop.
● If the towing bracket is incorrectly instal-
led, there i
s a serious danger of accident.
● For your own safety, please observe the tow
brack
et manufacturer's instructions. CAUTION
● If the po w

er socket is incorrectly installed,
this could cause damage to the vehicle elec-
trical system. Note
● SEA T r

ecommends that the towing hooks
be fitted at a specialised workshop. Consult
your SEAT dealer in case additional modifica-
tions to your vehicle are necessary.
● Due to the specific design of the exhaust,
the fitting of a c
onventional towing hook is not recommended for some sportier versions.

Advice
extra care. Refit the normal road wheel as
soon as
po
ssible. Wheel bolts
The design of wheel bolts is matched to the
rims. If diff
er

ent wheel rims are fitted, the
correct wheel bolts with the right length and
correctly shaped bolt heads must be used.
This ensures that wheels are fitted securely
and that the brake system functions correctly.
In certain circumstances, you should not use
wheel bolts from a different vehicle, even if it
is the same model ››› page 255. WARNING
If the wheel bolts are not tightened correctly,
the wheel c ou

ld become loose while driving.
Risk of accident.
● The wheel bolts must be clean and turn
eas
ily. Never apply grease or oil to them.
● Use only wheel bolts which belong to the
wheel.
● If the pr

escribed torque of the wheel bolts
is t
oo low, they could loosen whilst the vehi-
cle is in motion. Risk of accident! If the tight-
ening torque is too high, the wheel bolts and
threads can be damaged. CAUTION
The prescribed tightening torque for wheel
bolt s

for steel and alloy wheels is 120 Nm. Tyre monitoring indicator*

on. The tyre monitoring system compares wheel
r
ev
o

lutions alongside the wheel diameter of
each wheel, with help from the ESC. If the di-
ameter of a wheel changes, the tyre monitor-
ing indicator lights up . The wheel diame-
ter changes when:
● Tyre pressure is insufficient.
● The tyre structure is damaged.
● The vehicle is unbalanced because of a
load. ●
The wheel
s of

one axle are under more
pressure (for example, driving with a trailer or
on steep slopes).
● The vehicle is fitted with snow chains.
● The temporary spare wheel is fitted.
● The wheel on one axle is changed.
Tyr
e pressure adjustment
After modifying tyre pressure or changing any
wheels, the new tyre pressure must be stored
in the Easy Connect system with the  but-
t on and the S
ET

TINGS function button

 page 33.
You can also press and hold down the
››› Fig. 241 button with the ignition on, until
an acoustic signal is heard.
If the wheels are under excessive load (for ex-
ample, driving with a trailer or heavy load),
the tyre pressure must be increased to the
recommended value for a full load (see the
sticker on the back of the left front door
frame). If the tyre monitor system button is
pressed down, the new tyre pressures are
confirmed.
The tyre pressure control lamp  lights up
If the tyre pressure of a wheel is much lower
than the value set by the driver, then the tyre
pressure control lamp ››› will light up.

gi

slation in force at the time (for more infor-
mation, see the Publications Office of the Eu-
ropean Union on the EUR-Lex website: © Eu-
ropean Union, http://eur-lex.europa.eu/) and
apply to the specified vehicle characteristics.
The values relating to fuel consumption and
CO 2 emissions can be found in the documen-
tation provided to the purchaser of the vehi-
cle at the time of purchase.
Fuel consumption and CO 2 emissions depend
on the equipment/features of each individual
vehicle, as well as on the driving style, road
conditions, traffic conditions, environmental
conditions, load or number of passengers. Note
In practice, and considering all the factors
mentioned here, c on

sumption values can dif-
fer from those calculated in the current Euro-
pean regulations. Weights
Kerb weight refers to the basic model with a
f
uel
t

ank filled to 90% capacity and without
optional extras. The figure quoted includes
75 kg to allow for the weight of the driver.
Special versions, optional equipment fittings
or retro-fitting accessories will increase the
weight of the vehicle ››› . WARNING
● Ple a

se note that the centre of gravity may
shift when transporting heavy objects; this
may affect vehicle handling and lead to an ac-
cident. Always adjust your speed and driving
style to suit road conditions and require-
ments.
● Never exceed the gross axle weight rating
or the gros
s vehicle weight rating. If the per-
missible axle load or the permissible total
weight is exceeded, the driving characteris-
tics of the vehicle may change, leading to ac-
cidents, injuries and damage to the vehicle. Trailer mode
Tr
ai

ler weights The trailer weights and drawbar loads ap-
pr
o
v

ed are selected in intensive trials accord-
ing to precisely defined criteria. The ap-
proved trailer weights are valid for vehicles in
the EU for maximum speeds of 80 km/h (50
mph) (in certain circumstances up to 100
km/h (62 mph)). The figures may be different
in other countries. All data in the official vehi-
cle documentation takes precedence over
these data at all times ››› .

Technical specifications
Drawbar loads
The maximum permitt ed dr
a
wbar load on the
ball joint of the towing bracket must not ex-
ceed 75 kg.
In the interest of road safety, we recommend
that you always tow approaching the maxi-
mum drawbar load. The response of the trail-
er on the road will be poor, if the drawbar
load is too small.
If the maximum permissible drawbar load
cannot be met (e.g. with small, empty and
light-weight single axle trailers or tandem
axle trailers with a wheelbase of less than 1
metre), a minimum of 4% of the actual trailer
weight is legally required for the drawbar
load. WARNING
● For s af

ety reasons, you should not drive at
speeds above 80 km/h (50 mph) when towing
a trailer. This also applies in countries where
higher speeds are permitted.
● Never exceed the maximum trailer weights
or the drawb
ar load. If the permissible axle
load or the permissible total weight is excee-
ded, the driving characteristics of the vehicle
may change, leading to accidents, injuries
and damage to the vehicle. Wheels
Ty
r

e pressure and wheel bolts Tyre pressures
The stic
k

er with the tyre pressure values can
be found on the back of the left front door
frame. The tyre pressure values given there
are for cold tyres. Do not reduce the slightly
raised pressures of warm tyres ››› .
The pre s

sure for winter tyres is 0.2 bar higher
than that of summer tyres (2.9 psi / 20 kPa).
Wheel bolts
After the wheels have been changed, the
tightening torque of the wheel bolts should
be checked as soon as possible with a torque
wrench ››› . The tightening torque for steel
and al lo
y

wheels is 120 Nm. WARNING
● Check the ty

re pressure at least once per
month. Checking the tyre pressure is very im-
portant. If the tyre pressure is too high or too
low, there is an increased danger of accidents
- particularly at high speeds.
● If the tightening torque of the wheel bolts
is t
oo low, they could loosen while the vehi-
cle is in motion. Risk of accident! If the tight-
ening torque is too high, the wheel bolts and
threads can be damaged. Note
We recommend that you ask your Technical
Serv ic

e for information about appropriate
wheel, tyre and snow chain size. 287
