play on the Easy Connect screen
shows a slight time delay.
● To ensure that the parking aid works prop-
erly, the sensors must be kept clean and free
of ice and snow. Rear parking aid*
The rear parking aid is an audible assistant. Description
There are sensors integrated in the rear
bumper. When the sensors detect an obsta-
cle, you are alerted by audible warnings.
Make sure that the sensors are not covered
by adhesives, residues and the like, given
that this could affect the system operation.
Cleaning instructions
››› page 185.
The approximate measurement range of the
sensors is:
rearside0.90 m
centre1.60 m As you approach the obstacle, the time inter-
val between the audible warnings will be re-
duced. When you reach around 0.30 m the
warning will be constant: Do not continue to
move forward (or backward)

Trailer towing What do you need to bear in mind
when towing a trailer? Your vehicle may be used to tow a trailer
when fitted with the correct equipment.
If you wish to
retrofit a towing bracket, con-
s u
lt ››› page 180.
Connect
ors
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
u se an a

dapter 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
part 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 t
owing 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
to
wing bracket are for certification purposes
only. The correct figures for your specific
model, which may be lower than these fig-
ures for the towing bracket, are given in the
vehicle documentation or in ››› chapter Tech-
nical Data .
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
Set tyre pressure to the maximum permissi-
ble pressure shown on the sticker on the in-
side of the fuel tank flap. 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 178.
Tr
ailer rear lights
The trailer's rear lights should comply with
the statutory safety regulations ››› page 178. WARNING
Never transport people in a trailer. This could
result in fatal accidents. Note
● Towing 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 towing a trailer in your country. Hitching and connecting the trailer

Operation
You should always reduce speed immediately
if the trailer shows the slightest sign of snak-
ing . Never try to stop the “snaking” by in-
c r
easing speed.
Always brake in due course. If the trailer has
an overrun brake, apply the brakes gen
tly 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 71.
Electronic stability control*
The ESC* system helps to stabilise the trailer
in case of skidding or rocking. Retrofitting a towing bracket*

●
Driving with a trailer involves an extra effort
for the vehicle. 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).
● Certain 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 attachment points which
must be considered if you are retrofitting a
towing bracket. WARNING
The towing brackets should be fitted at a spe-
cialised workshop.
● If the towing bracket is incorrectly instal-
led, there is a serious danger of accident.
● For your own safety, please observe the tow
bracket manufacturer's instructions. CAUTION
● If the power socket is incorrectly installed,
this could cause damage to the vehicle elec-
trical system. Note
● SEAT recommends 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 conventional towing hook is
not recommended for some sportier versions.

for advice before purchasing accessories and
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-

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 holders, 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-
cording 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 excessivewear of components, and also invalidate your
vehicle 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. Two-way radios and office equipment
Radio transmitters (fixed installation)
Any retrofit 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
vehicle (and shielded cables are used togeth-
er with non-reflective aerial trimming).
● The effective transmitting power does not
exceed 10 Watts at the aerial base.

Care and maintenance
A SEAT Official Service and specialised work-
shop will be able to inform you about options
for installing and operating radio transmitters
with a higher
transmitting power.
Mo
bile 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 must, therefore, do not operate portable
mobile telephones or radio equipment inside
the vehicle without a properly installed exter-
nal aerial ››› .
Please note also that the maximum range of
the equipment can only be achieved with an
external aerial.
B u

siness 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 operated inside the vehicle without a prop-
erly installed external aerial can create exces-
sive magnetic fields that could cause a health
hazard. Note
● The posterior 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 instructions. Care and cleaning
General information Regular and careful care helps to
maintain
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
● Cleaning 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 reach of children. Failure to comply
could result in poisoning. For the sake of the environment
● If possible, use environmentally friendly
products.
● The remains of car care products should not
be disposed of with ordinary household
waste. Vehicle exterior care
Washing the vehicle The longer substances such as insects, bird
droppings, resinous tree sap, road dirt, in-
dustrial deposits, tar, soot or road salt and
other aggressive materials remain on the ve-
hicle, the more damage they do to the paint-
work. High temperatures (for instance due to
strong sunlight) further intensify the corro-
sive effect.
After the period when salt is put on the roads
it is important to have the underside of the
vehicle washed thoroughly.

Care and maintenance
Camera sensors and lenses ●
Use a small brush to remove snow and a
de-icer spray to remove ice.
● Clean the sensors with a solvent-free prod-
uct and a soft, dry cloth.
● Moisten the camera lens using a standard
alcohol-based glass cleaning agent and
clean the lens with a dry cloth. In the active
lane assist*, the area in front of the lens is
norm al
ly cleaned with the windscreen wash-
er. CAUTION
● When you clean the vehicle with a pressure
washer:
–Stay 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 ice from the reverse camera lens,
as it could crack the lens.
● Never use abrasive cleaning agents on the
lens. Care and polishing
Care
Waxing 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 .
P o

lishing
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 should be applied after polishing. CAUTION
● Do not use polishes 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 runs 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-
plated 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
neutr
a

l 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.
Plastic parts Plastic parts are cleaned with a power wash-
er. If this is not sufficient, plastic parts
should only be treated with a special solvent-
free
plastic cleaning agent
. Do not
u
se paint-
work cleaners, polishes or wax on plastic
parts.
