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

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

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

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 119. Electronic stability control*
The ESC* sys
tem helps to stabilise the trailer
in case of skidding or rocking.

●
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.

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-

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

Automatic car washes
B ef
or
e going through a car wash, be sure to
take the usual precautions (closing the win-
dows, roof and rear-view mirrors). If the vehi-
cle has special accessories such as spoilers
or a roof rack or two-way radio aerial, etc., it
is advisable to consult the car wash tunnel
operator.
It is best to use a car wash without revolving
bristles if possible.
Washing the vehicle with a high pressure
cleaner
When washing the vehicle with a high-pres-
sure cleaner, always follow the operating in-
structions for the equipment. This applies
particularly to the operating pressure and the
spraying distance. Do not hold the nozzle too
close to soft materials such as rubber hoses
or seals. The same applies to the parking aid
sensors*, which are located in the rear bump-
er.
Do not use a nozzle that sprays the water out
in a direct stream or one that has a rotating
jet for forcing off dirt.
Factory-fitted adhesive sheets
The following indications should be taken in-
to account to avoid damaging adhesive
sheets:
● Do not use high pressure cleaners. ●
Do not use s crapers to remove ice or snow
from the sheets.
● Do not polish the adhesive sheets.
● Do not use dirty cloths or sponges.
● It is preferable to wash them with a soft
spong
e and gentle neutral soap.
Washing the car by hand
When washing the car by hand, use plenty of
water to soften the dirt first, and rinse off as
well as possible.
Then clean the vehicle with a soft sponge,
glove or brush using only slight pressure.
You should start on the roof and work down.
Special car soap should only be used for very
persistent dirt.
Rinse the sponge or glove thoroughly and of-
ten.
Wheels, sills and similar should be cleaned
last. Use a second sponge for this. WARNING
● The v ehic

le should only be washed with the
ignition switched off. Failure to follow this in-
struction could result in an accident.
● Do not clean the underside of chassis, the
inside of
wheel arches or wheel trims without
protecting your hands and arms. You may cut
yourself on sharp-edged metal parts. Other-
wise, there is a risk of sustaining cuts. ●
When wa shin

g the car during the winter
season: water and ice in the brake system
can reduce braking effectiveness: risk of acci-
dent! CAUTION
● Do not wa

sh the vehicle in direct sunlight –
otherwise the paint can be damaged.
● Do not use sponges, abrasive household
spong
es or similar to clean insect remains.
This could damage the surface.
● Clean off stubborn dirt (insects, etc.) from
the headlight
s at regular intervals, for in-
stance when filling the fuel tank. The head-
lights should only be washed with water, do
not wipe them with a dry cloth or sponge. It
is best to use soapy water.
● Never wash tyres with a jet that sprays the
water out
in a direct stream. This could dam-
age the tyres even if the spray is kept at a
distance and only used for a very short time.
● Before washing the vehicle in an automatic
car wa
sh, please make sure to retract the ex-
terior mirrors to prevent them from being
damaged. Electrically retractable exterior
mirrors must not be folded in or out by hand,
always use the electrical power control. CAUTION
● Bef or

e washing the vehicle in an automatic
car wash, please proceed as follows to lock
the wiper arms so that they are not moved to-
wards the top of the windscreen: 258
