Towing bracket device
Trailer towing Wh at
do
you need to bear in mind
when towing a trailer? Your vehicle may be used to tow a trailer
when fitted w
ith the c

orrect equipment.
If you wish to retrofit a towing bracket, con-
sult ››› page 254.
Connectors
Your vehicle is fitted with a 13-pin connector
for the electrical connection between the
trailer and the vehicle.
If the trailer has a 7-pin plug you will need to
use an adapter cable. It is available at any
Technical Service.
Trailer weight/drawbar load
Never exceed the authorised trailer weight. If
you do not load the trailer up to the maxi-
mum 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. With increasing altitude the engine
power and therefore the vehicle 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 combination must be re- duced by 10% for every further 1000 m (or
par
t

thereof). The gross combination weight
is the actual weight of the laden vehicle plus
the actual weight of the laden trailer. When
possible, operate the trailer with the maxi-
mum permitted drawbar load on the ball joint
of the towing bracket, but do not exceed the
specified limit.
The figures for trailer weights and drawbar
loads that are given on the data plate of the
towing bracket are for certification purposes
only. The correct towing bracket figures for
your specific model, which may be lower than
these figures, are given in the vehicle docu-
mentation or on ››› page 289, Technical
specifications.
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.
Tyre pressure
The maximum permissible tyre pressure val-
ues are shown on the sticker on the back of
the left front door frame. Set the tyre pres-
sure of the trailer tyres in accordance with the
trailer manufacturer's recommendations. Exterior mirrors
Check whether
you can see enough of the
road behind the trailer with the standard rear
vision mirrors. If this is not the case, you
should have additional exterior mirrors fitted.
Both exterior mirrors should be mounted on
hinged extension brackets. Adjust the mirrors
to give sufficient vision to the rear.
Tow rope
Always use a cable between the vehicle and
the trailer ››› page 252.
Trailer rear lights
The trailer's rear lights should comply with
the statutory safety regulations ››› page 252. WARNING
Never transport people in a trailer. This could
re s

ult in fatal accidents. Note
● To w

ing a trailer places additional demands
on the vehicle. We recommend additional
services between the normal inspection inter-
vals if the vehicle is used frequently for tow-
ing a trailer.
● Find out whether special regulations apply
to to
wing a trailer in your country. 251

Safety lug
The safety lug B
› ›
› Fig. 244
is used to hook
up the trailer's retainer cable.
On hooking it up to the safety lug, the retain-
er cable should have slack in all the trailer
positions with respect to the vehicle (sharp
bends, reverse gear, etc.).
Headlights
The front part of the vehicle may be raised
when the trailer is connected and the light
may dazzle the rest of the traffic.
Adapt the height of the headlights using the
headlight range rotary adjuster 1)
. WARNING
● 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 ›››
 page 63.
● 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.
● When connecting and disconnecting the
trail
er, the towing vehicle's handbrake
should be applied.
● When the tow hitch ball has not been fitted,
the socket
should remain concealed in its
housing on the bumper. 1)
This does not apply for vehicles with bi-xenon
hea dlights.

Towing bracket device
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.

FLEON/LEON SCLEON ST
319 mm596 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 leg
al requirements in your country
must be observed (e.g. the fitting of a sepa-
rate control lamp).
● Certain vehicle components, e.g. the rear
bumper, mu
st 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
t

o 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.
Please consult your Technical Service. 255

replacement parts.
Your vehicle is designed to offer a high
standard of active and passive safety. For this
reason, we recommend that you ask a SEAT
Official Service for advice before fitting ac-
cessories or replacement parts. Your SEAT Of-
ficial Service has the latest information from
the manufacturer and can recommend acces-
sories and replacement parts which are suita-
ble for your requirements. They can also an-
swer any questions you might have regarding
official regulations.
We recommend you to use only SEAT acces-
sories and Genuine SEAT parts ®
. SEAT has
tested these parts and accessories for suita-
bility, reliability and safety. SEAT Official
Services have the necessary experience and
facilities to ensure that the parts are installed
correctly and professionally. Any
retro-fitted equipment which has a direct
effect
on the vehicle and/or the way it is driv-
en, such as a cruise control system or elec-
tronically-controlled suspension, must be
approved for use in your vehicle and bear the
e mark (the European Union's authorisation
symbol).
If any additional electrical devices are fitted
which do not serve to control the vehicle it-
self (for instance a refrigerator box, laptop or
ventilator fan, etc.), they must bear the 
sign (manufacturer conformity declaration in
the European Union). WARNING
Accessories, for example telephone holders
or cup ho l

ders, should never be fitted on the
covers, or within the working range of the air-
bags. Otherwise, there is a danger of injury if
the airbag is triggered in an accident. Technical modifications
Modifications must always be carried out ac-
c
or
din

g to our specifications.
Unauthorised modifications to the electronic
components, software, wiring or data transfer
in the vehicle may cause malfunctioning. Due
to the way the electronic components are
linked together in networks, other indirect
systems may be affected by the faults. This
can seriously impair safety, lead to excessive wear of components, and also invalidate your
vehicl

e registration documents.
You will appreciate that your SEAT dealership
cannot be held liable for any damage caused
by modifications and/or work performed in-
correctly.
We therefore recommend that all work should
be performed by a SEAT Official Service using
genuine SEAT parts ®
. WARNING
Incorrectly performed modifications or other
work on

your vehicle can lead to malfunctions
and cause accidents. Radio transmitters and office equip-
ment
Radio transmitters (fixed installation)
An
y
r

etrofit installations of radio transmitters
in the vehicle require prior approval. SEAT
generally authorises in-vehicle installations
of approved types of radio transmitters provi-
ded that:
● The aerial is installed correctly.
● The aerial is installed on the exterior of the
vehicl
e (and shielded cables are used togeth-
er with non-reflective aerial trimming).
● The effective transmitting power does not
exc
eed 10 Watts at the aerial base.

Care and maintenance
A SEAT Official Service and specialised work-
shop w i
l
l be able to inform you about options
for installing and operating radio transmitters
with a higher transmitting power.
Mobile radio transmitters
Commercial mobile telephones or radio
equipment might interfere with the electron-
ics of your vehicle and cause malfunctions.
This may be due to:
● No external aerial.
● External aerial incorrectly installed.
● Transmitting power more than 10 W.
You mus
t, therefore, do not operate portable
mobile telephones or radio equipment inside
the vehicle without a properly installed exter-
nal aerial ››› .
Pl e
a

se note also that the maximum range of
the equipment can only be achieved with an
external aerial.
Business equipment
Retrofit installation of business or private
equipment in the vehicle is permitted, provi-
ded the equipment cannot interfere with the
driver's immediate control of the vehicle and
that any such equipment carries the  mark.
Any retrofit equipment that could influence
the driver's control of the vehicle must have a
type approval for your vehicle and must carry
the e mark. WARNING
Mobile telephones or radio equipment which
is oper

ated inside the vehicle without a prop-
erly installed external aerial can create exces-
sive magnetic fields that could cause a health
hazard. Note
● The pos t

erior fitting of electric and elec-
tronic equipment in this vehicle affects its li-
cence and could lead to the withdrawal of the
vehicle registration document under certain
circumstances.
● Please use the mobile telephone/radio op-
erating in
structions. Care and cleaning
Gener a
l

information Regular and careful care helps to
maint
ain
the
value of the vehicle. This may also be one
of the requirements for upholding any war-
ranty claims in the event of corrosion or paint
defects.
SEAT Official Services and specialist retailers
carry stocks of suitable car care materials.
Please follow the instructions for use on the
packaging. WARNING
● Cle

aning products and other materials used
for car care can be damaging to your health if
misused.
● Always keep care products in a safe place,
out of the r
each of children. Failure to comply
could result in poisoning. For the sake of the environment
● If po s

sible, use environmentally friendly
products.
● The remains of car care products should not
be dispo
sed of with ordinary household
waste. Vehicle exterior care

Care and maintenance
–
the bonnet mu s
t be closed.
– switch the ignition on and off.
– press the windscreen wiper lever forward
briefly (windscreen washer function).
This will lock the wiper arms. For the sake of the environment
The car should only be washed in special
w ash b

ays. These areas are prepared to pre-
vent oily water from getting into the public
drains. In some places, washing vehicles out-
side the areas intended for this purpose is
prohibited. Camera sensors and lenses
●
Use a small brush to remove snow and a
de-ic er s
pr

ay to remove ice.
● Clean the sensors with a solvent-free prod-
uct and a soft, dr
y cloth.
● Moisten the camera lens using a standard
alcohol-b
ased glass cleaning agent and
clean the lens with a dry cloth. In the active
lane assist*, the area in front of the lens is
normally cleaned with the windscreen wash-
er. CAUTION
● When y ou c

lean the vehicle with a pressure
washer: –
Sta y

a suitable distance from the sensors
on the front and rear bumpers.
– Do not clean the camera lenses or sur-
rounding area with the pressure washer.
● Never use warm or hot water to remove
snow and ic
e from the reverse camera lens,
as it could crack the lens.
● Never use abrasive cleaning agents on the
lens. Waxing and polishing
Care
W
ax
in

g protects the paintwork. It is time to
apply a coat of good wax when water no lon-
ger forms droplets and rolls off the clean
paintwork.
Even if a wax solution is used regularly in the
vehicle washing tunnel, it is advisable to pro-
tect the paint with a hard wax coating at least
twice a year.
In the summer, you will find it is much easier
to remove dead insects (which accumulate
on the bumper and the front of the bonnet) if
the car has been treated with care products
recently.
Polishing
Polishing is only necessary if the paint has
lost its shine, and the gloss cannot be
brought back by putting on wax. If the polish does not contain wax, a wax
product shou

ld be applied after polishing. CAUTION
● Do not u se po

lishes and hard wax on pain-
ted parts with a matt finish or on plastic
parts.
● Do not apply paint polishes to the side trim
that ru
ns around the panoramic roof and ends
on the windscreen. However, it can be treated
with hard wax. Trims
In respect for the environment, the silver-
p
l
at

ed trims on the body are made of pure
aluminium (they do not contain chrome).
Dirt or marks on the trim mouldings should
be removed with a cleaning product with a
neutral PH (do not use a chrome cleaner).
Body polish is also unsuitable for use on trim
mouldings. The intensive cleaning fluids of-
ten used before the car goes into a car wash
may contain alkaline substances, which can
cause dull or milky patches when they dry
out.
SEAT Official Services carry stocks of cleaning
products which have been tested for use on
your vehicle and are not harmful to the envi-
ronment.
