Accessories, replacement of
parts and modifications Introduction WARNING
The use of spare parts and accessories, or in-
corr ectly

performed modifications or repairs
may result in damage to the vehicle, acci-
dents and serious injury.
● SEAT strongly recommends you to only use
SEAT ap
proved accessories and SEAT ®
origi-
nal spare parts. These parts and accessories
have been specially tested by SEAT for suita-
bility, reliability and safety.
● Have any repairs or modifications carried
out at a s
pecialised workshop. These work-
shops have the necessary tools, diagnostics
equipment, repair information and qualified
personnel.
● Only mount parts with the same specifica-
tions a
s the parts fitted at factory.
● Never mount, fasten or fit objects such as
drink hol
ders or telephone cradles over the
covers of the airbag modules or within their
deployment zones. ●
Only u

se wheels and tyre combinations
which have been approved by SEAT for your
vehicle type. Accessories and spare parts
SEAT recommends you consult an Official
Serv
ic

e before purchasing accessories and
spare parts or consumables. For example,
when fitting accessories at a later date, or
when replacing a component. A SEAT Official
Service will advise you as to the legal require-
ments and manufacturer's recommendations
regarding accessories, spare parts and other
components.
SEAT recommend you use only approved
SEAT accessories and genuine SEAT spare
parts ®
. These parts and accessories have
been specially tested by SEAT for suitability,
reliability and safety. In addition, SEAT tech-
nical services will guarantee that assembly is
performed professionally.
Although we continually monitor the market,
SEAT cannot guarantee that products not ap-
proved by SEAT are reliable, safe or suitable
for the vehicle. Therefore, SEAT cannot accept
liability, even in those cases authorised by
an officially recognised technical inspection
office or other official body.
Any retro-fitted equipment which has a direct
effect on vehicle control must be approved by SEAT for use in your vehicle and bear the
e
mark (the E

uropean Union's authorisation
symbol). This includes cruise control systems
or electronically controlled suspension.
If any additional electrical devices are fitted
which do not serve to control the vehicle it-
self, these must bear the  mark (European
Union manufacturer conformity declaration).
This includes refrigerator boxes, laptops or
ventilator fans. WARNING
Unprofessional repairs or modifications to
the v ehic

le may affect the performance of the
airbags, and may cause operating faults or fa-
tal accidents.
● Never mount, fasten or fit objects such as
drink hol
ders or telephone cradles over or
next to the covers of the airbag modules or
within their deployment zones.
● Objects placed over the airbag covers, or
within their deplo
yment zones, could lead to
serious injury or loss of life if the airbags are
triggered. Service fluids and components

Care and maintenance
The optimal reach of the equipment is only
ac hiev
ed w
ith an external aerial.
Check first with a specialised workshop that
understands the technical possibilities of in-
stallation if you wish to use a two-way radio
with a transmitting power of over 10 watts.
SEAT recommends taking your car in for tech-
nical service.
All legal requirements, together with the in-
structions for the use of two-way radios must
be observed. WARNING
If the two-way radio is not securely fastened
in pos ition, it

could be sent flying around the
vehicle in the event of sharp braking, sudden
manoeuvres or accident, causing injury.
● While driving, two-way radios must be se-
curely
fastened in position, outside the air-
bags deployment zones, or safely stowed
away. WARNING
When using a two-way radio without a con-
nection to an e xt

erior aerial, the maximum
permitted levels of electromagnetic radiation
may be exceeded. This is also the case if the
aerial has not been correctly installed.
● You should only use a two-way radio inside
the vehic
le if it has first been correctly con-
nected to an exterior aerial. Information stored by the control
u
nit
s Your vehicle is fitted at the factory with a ser-
ies
of

electronic control units responsible for
the engine and gearbox management. In ad-
dition, the control units supervise the per-
formance of the exhaust gas system and the
airbag systems.
Therefore, while the vehicle is being driven,
these electronic control units are continuous-
ly analysing the vehicle data. In the event of
faults or deviations from the theoretical val-
ues, only this data is stored. Normally, the
warning lamps on the instrument panel light
up in the event of faults.
This data can only be read and analysed us-
ing special equipment.
The storing of the data allows specialised
workshops to detect and repair faults. Stored
data may include:
● Data relating to the engine or the gearbox
● Speed
● Direction of travel
● Braking force
● Detection of seat belt
The v ehic

le control units never record conver-
sations held by passengers in the vehicle.
In vehicles equipped with an emergency call
function via the mobile phone or other appli- ances connected in the vehicle, it is possible
to send the v

ehicle position. If the control
unit records an accident with airbag activa-
tion, the system may automatically send a
signal. This will depend on the network oper-
ator. Normally, transmission is only possible
in areas with good coverage.
Event Data Recorder
The vehicle is not fitted with an event data re-
corder.
An event data recorder temporarily stores the
vehicle information. Therefore, in the event of
an accident, it is possible to obtain detailed
information about how the accident occur-
red. Vehicles with airbag systems can store
data relating to impact speed, seat belt sta-
tus, seat positions and airbag activation
times may be stored, etc. The volume of data
depends on the manufacturer.
Event data recorders can only be mounted
with authorisation from the vehicle owner
and, in some countries, they are governed by
local legislation.
Reprogramming control units
On the whole, all the data required for the
component management is stored in the con-
trol units. The programming of certain con-
venience functions, such as the turn signals,
individual door opening and instructions on
the display can be modified using special »

Introduction The dye from many items of modern clothing
(e.g. d
ark

jeans) is not always colour-fast.
Seat upholstery (material and leather), espe-
cially when light-coloured, may visibly discol-
our if the dye comes out of clothing (even
when used correctly). This is not an uphols-
tery defect but indicates that the dye in the
item of clothing is not sufficiently colour-fast. WARNING
Car-care products may be toxic and hazard-
ous. If c

ar care products are not suitable or
are used inappropriately, this could result in
accident, serious injury, burns or intoxica-
tion.
● Car care products must always be stored in
the original
container which should be kept
closed.
● Observe information provided by the manu-
factur
er.
● To prevent confusion, never store car care
products
in empty food cans, bottles or other
containers.
● Keep all care products out of reach of chil-
dren.
● Harmfu

l vapours may be produced when us-
ing car c
are products. Therefore, care prod- ucts should only be used in well-ventilated
sp
ac

es or in the open air.
● Never use fuel, turpentine, engine oil, ace-
tone or any
other volatile liquid to wash,
clean or care for the vehicle. These are toxic
and highly flammable. WARNING
Inappropriate care and cleaning of vehicle
c omponent s

may effect the vehicle safety
equipment, increasing the risk of severe in-
jury.
● Vehicle components should only be
cle
aned and maintained in accordance with
the manufacturer's instructions.
● Only use approved or recommended care
products. CAUTION
● Cle

aning products which contain solvents
will damage the material.
● To avoid damage, stubborn stains should
be remov
ed by a specialised workshop. Note
Suitable vehicle care products are available
from y

our technical service. How to care for the upholstery
To treat and maintain your seat upholstery,
keep the f
o

llowing in mind ››› :
● Before entering the vehicle, close any Vel-
cr o f

asteners that might snag on the uphols-
tery or trim fabric. Any open Velcro fasteners
may damage the trim or upholstery fabrics.
● To prevent damage, avoid direct contact
between sharp dec
orative objects and the
upholstery and trim fabrics. Decorative ob-
jects include zips, rivets and rhinestones on
clothing and belts.
● From time to time, clean the dust that gath-
ers in the per

forations, folds and seams so
that the surfaces of the seats are not dam-
aged by its abrasive effect.
● Make sure clothes are colour-fast to avoid
them running and s
taining the upholstery.
This is especially important if the upholstery
is light in colour. CAUTION
If the instructions for upholstery and trim
car e ar

e not followed, they may deteriorate
and discolour. Note
SEAT recommends you take the vehicle to a
Spec i

alised workshop to treat any stains on
the upholstery caused by the discolouration
of clothing. 176

s to become porous. If an airbag is ac-
cidentally triggered, the detachment of plas-
tic parts could cause serious injury.
● Never clean the dash panel and the surfa-
ces
of the airbag modules with cleaners con-
taining solvents. Cleaning seatbelts
If the seat belt is very dirty, the belt retractor
m
a
y

not work correctly thus preventing the
seat belt from operating correctly.
The seat belts should never be removed from
the vehicle for cleaning.
● Use a soft brush to remove the worst dirt
›››
.
● Pull the seat belt right out and leave it out.
● Clean dirty seat belts with a gentle
so
ap
and water solution.
● Wait until they are completely dry.
● Only allow the seat belt to retract when it is
compl
etely dry. WARNING
Check the condition of all the seat belts at
re gu

lar intervals. If the webbing or other
parts of the seat belt are damaged, the vehi- cle should be taken to a Specialised work-
shop immediat
ely

and the belts should be re-
placed. It is extremely dangerous to drive us-
ing damaged seat belts and could result in
serious injury or loss of life.
● Seat belts and their components must nev-
er be cle
aned with chemical products, nor
should they be allowed to come into contact
with corrosive liquids, solvents or sharp ob-
jects. This could affect the strength of the
seat belt webbing.
● Seat belts should be completely dry before
retractin
g. Dampness could damage the belt
retractor so that it does not operate correctly.
● Do not allow liquids or foreign bodies to en-
ter the buc
kle fastenings. This could damage
the buckles and seat belts.
● Never attempt to repair, modify or remove a
seat belt
yourself.
● Always have damaged seatbelts replaced
immediately
by seat belts approved for the
vehicle in question by SEAT. Seat belts which
have been worn in an accident and stretched
must be replaced by a specialised workshop.
Renewal may be necessary even if there is no
apparent damage. The belt anchorage should
also be checked. 178

Advice
It may be necessary to fit or remove certain
piec e
s
of equipment or to deactivate certain
functions. Service work may also be affected.
This is particularly true if the vehicle is used
in a different climate for an extended period
of time. CAUTION
● SEA T doe

s not accept liability for any dam-
age to the vehicle due to the use of a lower
quality fuel, an inadequate service or the
non-availability of genuine spare parts.
● SEAT does not accept liability if the vehicle
does not

Advice
WARNING
The high voltages of the electrical system can
give el ectric
shocks as well as causing burns
and serious injury and possibly even death!
● Never cause short circuits in the electrical
syst
em. The battery could explode.
● To minimise the risk of electric shock and
serious c
onsequences while the engine is
running or starting the engine, note the fol-
lowing:
– Never touch the electrical wiring of the
ignition system. WARNING
In the engine compartment, there are rotat-
ing p ar

ts that could cause serious injury.
● Never place your hands directly on or near
the radi
ator fan. Touching the rotor blades
could seriously harm you. The ventilator
works according to the engine temperature
and could start suddenly even when the igni-
tion is turned off and the key is removed.
● If any work has to be performed when the
engine is
started or with the engine running,
there is an additional, potentially fatal, safety
risk from rotating parts, such as the drive
belts, alternator, radiator fan, etc., as well as
from the high-voltage ignition system. Al-
ways work with the utmost caution.
– Always make sure that no parts of your
body, jewellery, ties, loose clothing and
long hair can be trapped by the rotating
parts of the engine. Before any work, re- move ties and jewellery (necklaces, etc),
tie long h
air b

ack and tie all items of
loose clothing to your body to make sure
that they cannot be trapped by engine
components.
– Take extreme caution when operating the
accelerator and remain attentive. The ve-
hicle could move, even if the handbrake
is applied.
● Always make sure you have not left any ob-
jects, s
uch as cleaning cloths and tools, in
the engine compartment. If any object is left
in the engine compartment, this could cause
malfunctions, engine faults and even a fire. WARNING
Refill liquids and certain materials can catch
fire e a

sily in the engine compartment, caus-
ing a fire and serious injury!
● Never smoke.
● Never work close to places exposed to
flames
or sparks.
● Never pour service fluids over the engine.
These fluid ma
y ignite hot engine parts and
cause injuries.
● If it is necessary to work on the fuel system
or the electrica
l system, please follow the in-
structions below:
–Always disconnect the vehicle battery.
– Never work close to heaters, heat sources
or places exposed to flames or sparks. ●
Alw a

ys keep a recently serviced and per-
fectly working fire extinguisher close by.
● Never cover the engine with additional in-
sul
ating materials such as a blanket. Risk of
fire! WARNING
If the bonnet is not correctly closed, it could
s ud den

ly open while driving leaving the driv-
er without visibility. This could result in a se-
rious accident.
● After closing the bonnet, always check that
it is
properly secured by the locking mecha-
nism in the lock carrier piece. The bonnet
must be flush with the surrounding body pan-
els.
● While driving, if you notice that the bonnet
is not
correctly closed then stop immediately
and close it correctly.
● Make sure the bonnet is opened and closed
safely
(when the engine is off, no smoke is
coming from the engine compartment, there
is enough space around the car, no people
are near, etc.). CAUTION
● When refi l

ling or changing service liquids,
ensure that you put the liquids into the right
tank. Making a mistake when refilling could
cause serious malfunctions and damage the
engine! 188
