Care and maintenance
consumables should be changed at a speci-
alised workshop. Technical services are per-
manently informed of any modifications. WARNING
The incorrect use or handling of fluids or con-
sumables may result in accident, serious in-
jury, burns or intoxication.
● Therefore, fluids must always be stored
closed in their original container.
● Never store fluids in empty food containers
or bottles as other people may accidentally
drink the fluid.
● Keep all fluids and consumables out of
reach of children.
● Read and observe the information and
warnings given on the fluid containers.
● Only work in the open air or in well-ventila-
ted zones, when using products which give
off harmful vapours.
● Never use fuel, turpentine, engine oil, ace-
tone or any other volatile liquid in the main-
tenance of the vehicle. These are toxic and
highly flammable. They could lead to fire or
explosions! CAUTION
● Only use appropriate fluids. Do not confuse
fluids as this can cause serious malfunctions
or engine damage.
● Accessories and other components moun-
ted in front of the air inlet reduce the cooling effect of the coolant. If the engine is running
under great strain in high outside tempera-
tures, it could overheat.
For the sake of the environment
Leaking fluids could pollute the environment.
Collect any spilt fluids in suitable containers
and dispose of them in accordance with legis-
lation and with respect for the environment. Repairs and technical changes
When performing repairs and technical mod-
ifications, SEAT's directives must be ob-
served!

›
›› Unauthorised modifications to the electronic
components or software in the vehicle may
cause malfunctions. Due to the way the elec-
tronic components are linked together in net-
works, other indirect systems may be affec-
ted by the faults. This may significantly affect
the vehicle's performance, increase compo-
nent wear and could mean that the vehicle
registration documents are no longer valid.
Your SEAT Official Service cannot be held lia-
ble for any damage caused by technical mod-
ifications or repairs performed incorrectly.
The SEAT Official Service does not accept lia-
bility for damage resulting from technical
modifications or repairs performed incorrect-ly; neither is the SEAT warranty valid in these
cases.
SEAT recommends you have any technical
modifications or repairs performed at a SEAT
Official Service and that you use
genuine
SEAT spare parts ®
.
Vehicles with special accessories and
equipment
The manufacturers of additional equipment
guarantee that the equipment complies with
applicable laws and regulations with respect
to the environment, in particular Directives
2000/53/CE and 2003/11/CE. The first direc-
tive governs the disposal of end-of-life vehi-
cles while the second refers to the restric-
tions on the marketing and use of certain
dangerous substances and preparations.
The vehicle owner should keep the documen-
tation for the additional equipment safely
and hand it over to the scrap yard at the end
of the vehicle's service life. This ensures that
any additional equipment mounted in end-of-
life vehicles is correctly disposed of with re-
spect for the environment. WARNING
Repairs or modifications which are not per-
formed correctly may result in damage or er-
rors in the vehicle operation, affecting the ef-
fectiveness of the driver assist systems. This
could result in serious accident. » 119Technical specifications

Care and maintenance
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 position, 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 exterior 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 vehicle if it has first been correctly con-
nected to an exterior aerial. Information stored by the control
units
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 vehicle 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 vehicle 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-
c or
der.
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 »

. WARNING
The improper use of the lifting platform or
the jack when raising the vehicle may result
in accidents or serious injury.
● Before raising the vehicle, please observe
the manufacturer's instructions for the plat-
form or jack, and the legal requirements,
where applicable.
● There should not be anyone inside the ve-
hicle when it is being raised or once it is in
the air.
● Only use the jacking points indicated in the
figures ››› Fig. 96 and ››› Fig. 97
when raising
the v
ehicle. If the vehicle is not lifted at the
indicated points, it may fall from the platform
while the engine or gearbox is being dis-
mounted, for example.
● The jacking points should be centrally
aligned and firmly positioned on the platform
support plates. ●
Never start the engine when the vehicle is
raised! The vehicle may fall from the platform
due to the engine vibrations.
● If it is necessary to work underneath the ve-
hicle while it is raised, you should check that
the supporting stands have an adequate load
capacity.
● Never climb onto the lifting platform.
● Always make sure that the weight of the ve-
hicle does not exceed the lifting platform
load capacity. CAUTION
● Never raise the vehicle at the engine oil
sump, the gearbox or the rear or front axles.
● Always use an intermediate rubber support
to prevent damage to the vehicle underbody. Check that the arms of the lifting platform are
able to move with obstruction.

Car-care products may be toxic and hazard-
ous. If car 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-
facturer.
● 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.
● Harmful vapours may be produced when us-
ing car care products. Therefore, care prod-
ucts should only be used in well-ventilated
spaces 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
components may effect the vehicle safety
equipment, increasing the risk of severe in-
jury.
● Vehicle components should only be
cleaned and maintained in accordance with
the manufacturer's instructions.
● Only use approved or recommended care
products. CAUTION
Cleaning products which contain solvents will
damage the material. For the sake of the environment

this purpose, to prevent dirty water which
may be contaminated by oil, grease or fuel,
from entering the drains. In some places,
even washing it outside the planned areas is
banned. For the sake of the environment
Where possible, always use products which
respect the environment. For the sake of the environment
The remains of car care products should not
be disposed of with ordinary household waste. Observe information provided by the
manufacturer.
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. The vehicle
undercarriage should
also be thoroughly washed at regular inter-
vals.
Automatic car washes
Always observe the instructions provided at
the automatic car wash. The standard pre-
cautionary measures prior to entering the car
wash should be taken to avoid damage to
the vehicle (close all windows, fold in exterior
mirrors). If the vehicle is fitted with additional
components (spoiler, roof-rack, aerial, etc.),
check with the car wash supervisor whether
these can enter the car wash ››› .
The vehicle paintwork is so durable that the
vehicle can normally be washed without
problems in an automatic car wash tunnel.
However, wear and damage to the paintwork
will depend on the type of car wash used.

Advice
●
Do not clean or polish them in sandy or
dusty environments.
● Do not use abrasive cleaning agents such
as home cream cleaners.
● Do not use insect sponges, scouring pads,
or similar products to clean insect deposits.
● Do not polish dirty surfaces.
● Do not use products containing solvents.
● Do not use hard wax. CAUTION
Chrome hub caps or wheel covers may have
been painted additionally. Do not treat them
with aluminium or chrome wax products, nor
chrome or aluminium polish. Instead, use
commercial paint wax or polish. Cleaning wheels
Cleaning steel wheels
Use an industrial cleaner to remove brake
dust. Therefore, clean wheels regularly with a
separate sponge.
Any damage to the paint on steel wheels
should be touched up before the metal starts
to rust.
Caring for and cleaning alloy wheels
Remove road salt and brake dust by washing
the wheels approximately
once a fortnight.Use an acid free detergent to clean the wheel
rims. SEAT recommends treating the wheel
rims thoroughly with a
hard wax about once
ev er
y three months.
It is important to remove road salt and brake
dust by washing the wheels at regular inter-
vals, otherwise the finish will be impaired.
Always use an acid-free detergent for alloy
wheel rims. Car polish or other abrasive
agents should not be used for maintaining
the rims.
If the protective coating on the paint has
been damaged (for example, hit by a stone),
it should be repaired immediately.
Caring for rubber seals The rubber seals on doors, windows, etc., re-
main flexible, provide a better seal and last
longer if they are regularly treated with a
product specifically designed for use on rub-
ber.
Before applying the product, use a soft cloth
to remove dust and dirt from the rubber
seals.De-icing the door lock cylinder To de-ice the lock cylinders, SEAT recommend
the use of genuine SEAT spray with lubricat-
ing and anti-corrosive properties.
CAUTION
The use of products containing degreasing
agents to de-ice the locks may rust the lock
cylinder. Protection of vehicle undercarriage
The vehicle underbody is coated to protect it
from chemical and mechanical damage. The
protective coat on the undercarriage may
wear from use while driving. Therefore, SEAT
recommends that the protective coating on
the undercarriage and on the running gear
should be regularly checked, and repaired if
necessary.
WARNING
Additional underseal or anti-corrosion prod-
ucts could catch fire due to the high tempera-
tures reached by the exhaust gas system and
other engine components.
● Do not apply additional underseal or anti-
corrosion products to the exhaust pipes, cat-
alytic converters, heat shields or other parts
of the vehicle which reach high temperatures. 130

Care and maintenance
Cleaning the engine compartment The engine compartment of any motor vehi-
cle is a potentially hazardous area
››› page 143.
The en gine c
ompartment should only be
cleaned by qualified personnel. If it is not
correctly cleaned, the anti-corrosion coating
and consequently electrical components may
be damaged. Moreover, water may filter di-
rectly into the vehicle interior through the wa-
ter chamber ››› .
If the engine compartment is very dirty, al-
ways take the vehicle to a specialised work-
shop for professional cleaning. SEAT recom-
mends taking your car in for technical serv-
ice.
Water box
The water box is in the engine compartment,
between the windscreen and the engine, and
beneath a perforated cover. Air is taken in
through the water box from outside to the ve-
hicle interior via the heating and air condi-
tioner.
Leaves and other loose objects should be
regularly cleaned away from the water box ei-
ther by hand or with a vacuum. WARNING
When working on the engine or in the engine
compartment, there is a risk of injury, burns,
accident or fire.
● Before starting work, please ensure you are
familiar with the required procedure and the
safety precautions ››› page 143.
● SEAT recommends getting a specialised
workshop to do these jobs. CAUTION
If water is manually poured into the water box
(e.g. using a high pressure cleaning appli-
ance), this could cause significant damage to
the vehicle. For the sake of the environment
Only wash the engine compartment in areas
allocated for this purpose, to prevent dirty
water which may be contaminated by oil,
grease or fuel, from entering the drains. In
some places, even washing this compartment
outside planned areas for this purpose is
banned. Caring for and cleaning the

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

To treat and maintain your seat upholstery,
keep the following in mind
››› :
● Before entering the vehicle, close any Vel-
cro fasteners 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 decorative 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 perforations, 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 staining the upholstery.
This is especially important if the upholstery
is light in colour. CAUTION
If the instructions for upholstery and trim
care are not followed, they may deteriorate
and discolour. Note
SEAT recommends you take the vehicle to a
Specialised workshop to treat any stains on
the upholstery caused by the discolouration
of clothing. Padding and fabric trim cleaning
Normal cleaning
●
Before applying cleaning products, please
read the instructions for handling and the
warnings shown on the container.
● The upholstery, textile covers, and carpet
should be regularly vacuumed (with vacuum
brush).
● We recommend that you use a soft sponge
or lint-free, micro-fibre cloth for normal clean-
ing ››› .
General superficial dirt on upholstery and
textile covers can be cleaned with a normal
foam cleaning product.
If the upholstery and the material trims are
very dirty, we recommend you have them
cleaned by a specialist cleaning form.
Cleaning stains
It may be necessary to clean the whole sur-
face and not only the stain itself. Especially if
the surface has been dirtied through normal
use. Otherwise, the stained area may be-
come lighter than the rest of the surface after
treatment.

Warnings relating to handling the
City Safety Assist system radar sensor func-
tion Some parts in the engine compartment come
from the factory with certificates of safety, la-
bels or plates containing important informa-
tion regarding the operation of the vehicle,
for example, on the petrol cap, on the pas-
senger's sun visor, on the driver door strut, or
on the floor of the boot.
● Never remove these certificates of safety,
labels or plates, and ensure they are kept in
good condition and are legible.
● If a vehicle part, bearing a certificate of
safety, label or plate, is replaced, the special-
ised workshop should attach the information
back in the same place. Certificate of safety
A certificate of safety on the door strut states
that all the safety standards and regulations
established by the national traffic authorities
responsible for road safety were met at the
time of manufacture. It may also give the
month and year of manufacture, together
with the chassis number.

U s
ing your vehicle in other countries
and continents The vehicle is manufactured at the factory for
use in a particular country in accordance with
the national legislation in force at the time of
manufacture.
If the vehicle is sold in another country or
used in another country for an extended peri-
od of time, the applicable legislation of that
country should be observed.It may be necessary to fit or remove certain
pieces 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.
As there are different types of frequency
bands around the world, you may find that
the radio system or the Portable Navigation
System (supplied by SEAT) supplied at the
factory does not work in another country.
CAUTION
● SEAT does 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 comply in part or in full with the le-
gal requirements of other countries or conti-
nents. Radio reception and the aerial
