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.

Products suitable for the care of your vehicle
are available at any technical service. WARNING
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
Only wash the vehicle 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 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

Fuel Introduction You will find a factory-fitted sticker containing
information on the type of fuel for your vehi-
cle on the inside of the fuel tank flap.
WARNING
Refuelling or handling fuel carelessly can
cause an explosion or fire resulting in serious
burns and injuries.
● Fuel is a highly explosive, easily flammable
substance.
● Observe current safety instructions and lo-
cal regulations concerning the handling of
fuel. Types of fuel
The type of fuel to use when refilling will de-
pend on the vehicle's engine. You will find a
factory-fitted sticker containing information
on the type of fuel for your vehicle on the in-

Petrol Petrol types
Vehicles with petrol engines must refuel us-
ing unleaded petrol according to European
norm EN 228
››› .
Petrol types are categorised according to
their octane number (e.g. 91, 95, 98 or 99
RON (RON = “Research Octane Number”).
You may use petrol with a high octane num-
ber than the one recommended for your en-
gine. However, this has no advantage in
terms of fuel consumption and engine power.
SEAT recommends refuelling with a low sul-
phur content or sulphur-free petrol to reduce
fuel consumption for petrol engines. Petrol additives
The quality of the fuel influences the behav-
iour, power and service life of the engine.
This is why the petrol you use should carry
suitable additives already included by the
petrol industry, free of metals. These addi-
tives will help to prevent corrosion, keep the
fuel system clean and prevent deposits from
building up in the engine.
If good-quality petrol with metal-free addi-
tives is not available or engine problems
arise, the necessary additives must be added
when refuelling
››› .
Not all petrol additives have been shown to
be effective. The use of unsuitable petrol ad-
ditives may cause significant damage to the
engine and the catalytic converter. Metal ad-
ditives should never be used. Metal additives
may also be contained in petrol additives for
improving anti-detonation ratings or octane
ratings ››› .
SEAT recommends “genuine Volkswagen
Group Fuel Additives for petrol engines”.
These additives can be bought at SEAT deal-
ers, where information on how to use them
can also be obtained. CAUTION

Filling the tank Introduction The fuel tank flap is on the rear right of the
vehicle.
WARNING
Refuelling or handling fuel carelessly can
cause an explosion or fire resulting in serious
burns and injuries.
● Always make sure that you correctly close
the fuel cap to avoid evaporation and fuel
spillage.
● Fuels are highly explosive and inflammable
substances that can cause serious burns and
injuries.
● Fuel could leak out or be spilt if the engine
is not switched off or if the filler fuel nozzle is
not fully inserted into the tank filler neck
when refuelling. This could lead to a fire, ex-
plosion and severe injuries.
● When refuelling, turn off the engine and
turn off the ignition for safety reasons.
● Always turn off mobile telephones, radio
apparatus and other radio wave emitting
equipment before refuelling. Electromagnetic
waves could cause sparks and lead to a fire.
● Never enter the vehicle while refuelling. If it
is absolutely necessary to enter, close the
door and touch a metal surface before touch- ing the filler nozzle again. This will prevent
the generation of static electricity. Sparks
could cause a fire when refuelling.
●
Never handle fuel close to flames, sparks or
objects with slow combustion (e.g. ciga-
rettes).
● Avoid static electricity and electro-magnet-
ic radiation when refuelling.
● Observe the safety regulations of the serv-
ice station.
● Never spill fuel on the vehicle or in the lug-
gage compartment. WARNING
For safety reasons, SEAT does not recommend
carrying a spare fuel canister in the vehicle.
Fuel could be spilled and catch fire, above all
in case of an accident and this applies to a
full container as well as empty containers.
This could lead to explosions, fires and inju-
ries.
● Observe the following if you exceptionally
have to carry fuel in a canister:
–Never place a fuel container, to fill it, in-
side the vehicle or on the vehicle, for ex-
ample, in the luggage compartment. Fill-
ing in these circumstances could create
an electrostatic charge and spark that
could ignite fuel fumes.
– Always place the canister on the ground
to fill it. –
Insert the fuel nozzle into the neck of the
canister as far as possible.
– If you are using a metal fuel canister, the
nozzle must always touch the canister
while it is being filled to avoid static elec-
tricity.
– Follow the legal requirements for the use,
storage and transport of spare fuel canis- ters.
– Insure that the fuel container complies
with manufacturing standards, for exam-
ple, ANSI or ASTM F852-86. CAUTION
● Always remove any fuel spilled anywhere
on the vehicle to avoid damage to the wheel
housing, the tyre and vehicle paintwork.
● Refuelling a petrol engine with diesel can
cause serious engine and fuel system dam-
age; the resulting malfunctions are not cov-
ered by the SEAT warranty. If you refuel with
the wrong type of fuel, never start the engine.
This applies to even the smallest amount of
the wrong fuel. Seek specialist assistance.
With the engine running, the composition of
the wrong fuel could significantly damage the
fuel system and the engine itself. For the sake of the environment
Fuels can contaminate the environment. Col-
lect any spilt service fluids and allow a pro-
fessional to dispose of them. 139Technical specifications

Problem:
if the vehicle is left parked for a
long time just after refuelling, the gas level
indicator does not accurately indicate the
same level shown after refuelling when the
vehicle is started up again. This is not due to
a leak in the system, but to a drop in pres-
sure in the gas tank for technical reasons af- ter a cooling phase immediately after refuel-
ling. WARNING
Driving with insufficient fuel reserve could re-
sult in the vehicle breaking down in traffic
and a serious accident.
● If the fuel level is too low then the fuel sup-
ply to the engine can become irregular espe-
cially on slopes.
● If the engine “is choked” or stalls due to
lack of or irregularity of the fuel supply, the
power steering as well as all of the driver as-
sistance systems including braking assis-
tance will stop working.
● Always refuel when there is only one quar-
ter of the fuel tank left to avoid running out of
fuel. CAUTION
● Always pay attention to any lit control
lamps and to the corresponding descriptions and instructions to avoid damage to the vehi-
cle.
● Never run the fuel tank completely dry. An
irregular fuel supply may lead to ignition
faults and unburnt fuel could enter the ex-
haust system. This could damage the catalyt-
ic converter. Note

Check that the gas filler mouth retainer 2 is not trapped with the filler nozzle. If neces-
sary, place it in the filler mouth again.
●
Insert the plug in the filler mouth.
● Close the tank flap. Make sure you hear it
click into place. WARNING
Natural gas is a highly explosive, easily flam-
mable substance. Incorrect handling of the
natural gas can cause accidents serious
burns and other injuries.
● Before refuelling with natural gas, the fill-
ing mouth must be correctly engaged. If you
can smell gas, stop refuelling immediately. WARNING
The vehicle is not prepared to use liquefied
natural gas (LNG) and this fuel must not be
added under any circumstances. Liquefied
natural gas can cause the natural gas tank to
explode, resulting in serious injury. Note
● The filling nozzles of natural gas pumps
can differ in the way they are operated. If you
are unacquainted with the pump, it is advisa-
ble that a member of staff of the service sta-
tion performs the refuelling operation. ●
Noises heard when refuelling are normal
and do not indicate the presence of a fault in
the system.
● The vehicle natural gas system is prepared
both for refuelling with a small compressor
(slow refuel) and a large compressor (fast re-
fuel) in natural gas service stations. Bonnet
