Care and maintenance
running gear, and retouch it if necessary,
before and after the winter season.
We recommend that you go to your Technical
Service to carry out repair work and addition-
al anti-corrosion work. WARNING
Do not apply underseal or anti-corrosion
coatings to the exhaust pipes, catalytic con-
verter or the heat shields on the exhaust sys-
tem. The heat of the exhaust system or the
engine could cause them to ignite. Risk of
fire. Cleaning the engine compartment
Take special care when cleaning the engine
compartment.
Anti-corrosion treatment
The engine compartment and the surface of
the power unit are given anti-corrosion treat-
ment at the factory.
Good corrosion protection is particularly im-
portant in winter when the vehicle is fre-
quently driven on salted roads. To prevent
the salt corroding the vehicle, the entire en-
gine compartment should be thoroughly
cleaned before and after winter.
Technical Services
have the proper products
for cleaning and preservation as well as the necessary workshop equipment. For this rea-
son, we recommend having this work per-
formed by them.
The anti-corrosion protection is usually re-
moved if the engine compartment is cleaned
with grease removing solutions, or if you
have the engine cleaned. On commissioning
this work, ensure that all surfaces, seams,
joints and components in the engine com-
partment are given anti-corrosion treatment.
WARNING
● When working in the engine compartment,
always observe the safety warnings
››› page 163.
● Bef
ore opening the bonnet, switch the en-
gine off, apply the handbrake firmly and al-
ways remove the key from the ignition.
● Allow the engine to cool before you clean
the engine compartment.
● Do not clean, for example, the vehicle un-
derbody, wheel arches or wheel trims without
protecting your hands and arms. You may cut
yourself on sharp-edged metal parts. Failure
to comply could result in injury.
● Moisture, ice and salt on the brake system
may affect braking effectiveness. Risk of acci-
dent. Directly after washing, avoid sudden
and sharp braking.
● Never touch the radiator fan. It is tempera-
ture-controlled and could start automatically,
even when the key is removed from the igni-
tion! For the sake of the environment
Fuel, grease and oil deposits can be removed
when the engine is washed. The polluted wa-
ter must be cleaned in an oil separator. For
this reason, engine washing should be car-
ried out only by a specialised workshop or a
petrol station. Caring for the vehicle interior
Introduction The dye used in many modern garments, for
example dark jeans, is not always sufficiently
colour-fast. Seat upholstery (material and
leather), especially when light-coloured, may
visibly discolour if the dye comes out of
clothing (even when used correctly). This is
not an upholstery defect but indicates that
the dye in the item of clothing is not suffi-
ciently colour-fast.
The longer stains or dirt remain on the vehi-
cle surfaces, especially the fabrics covering
the padded upholstery, the more difficult it
becomes to clean and maintain them. If
stains and dirt are left for a long time, it may
be that they are impossible to remove.

using them in the wrong way, may cause acci-
dents, serious injury, burns or intoxication.
●
Keep your car-care products in their origi-
nal containers.
● Read the instructions.
● Never keep car-care products in empty food
containers, bottles or other similar contain-
ers. Other people may confuse them.
● Keep all car-care products out of the reach
of children.
● Some products may give off harmful va-
pours during use. Therefore, they should be
used outdoors in well-ventilated places.
● Never use fuel, turpentine, engine oil, nail-
varnish remover or any other volatile product
for washing, maintenance or cleaning. These
are toxic and highly flammable. WARNING
Unsuitable maintenance and cleaning of vehi-
cle components may impair proper operation
of safety equipment and cause serious injury.
● Maintain and clean vehicle components ac-
cording to the manufacturer's instructions.
● Only use approved or recommended clean-
ing products. CAUTION
● Cleaning products which contain solvents
have a corrosive effect and may damage the
material irreparably. ●
Stains and dirt containing aggressive sub-
stances or solvents attack the material and
may damage it irreparably, even when they
are cleaned quickly.
● Dirt and stains should not be allowed to dry
and should be cleaned as quickly as possible.
● In the case of stubborn stains, take the ve-
hicle to a specialised workshop to avoid dam-
age. Treating your upholstery
To treat and maintain your seat upholstery,
keep the following in mind
››› :
Before entering the vehicle, close any Velcro
fasteners that might snag on the upholstery
or trim fabric. Any open Velcro fasteners may
damage the trim or upholstery fabrics.
To prevent damage, avoid direct contact be-
tween sharp decorative objects and the up-
holstery and trim fabrics. Decorative objects
include zips, rivets and rhinestones on cloth-
ing 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 you ignore this checklist, which is impor-
tant for maintaining your seat upholstery, the
fabric may be damaged or stained.
● Consult the checklist and carry out the op-
erations it describes. Note
SEAT recommends you take the vehicle to a
specialised workshop to treat any stains on
the upholstery caused by the discolouration
of clothing. How to clean the upholstery, trim

rear seats. If these seats and seat backrests
are damaged, or are cleaned and are treated
incorrectly, or if they get wet, the vehicle
electric system may be destroyed and the air-
bag system damaged

Checking and refilling levels
●
When filling the fuel tank after having run it
completely dry on a vehicle with a diesel en-
gine the ignition must be switched on for at
least 30 seconds before starting the engine.
Subsequently, when you start the engine it
may take longer than normal to start firing
(up to one minute). This is due to the fact that
the fuel system has to purge itself of air be-
fore starting. For the sake of the environment
Do not try to put in more fuel after the auto-
matic filler nozzle has switched off; this may
cause the fuel to overflow if it becomes warm. Petrol
Petrol types The recommended fuel types are listed on a
sticker inside the fuel tank flap.
Only
unleaded petrol conforming to standard
DIN EN 228 may be used for vehicles with
c at
alytic converters (EN = “European Stand-
ard”).
Petrol types are categorised according to
their
octane number, e.g. 91, 95, 98 RON
(RON = “research octane number”). You may
use petrol with a higher octane number than
the one recommended for your engine. How- ever, this has no advantage in terms of fuel
consumption and engine power. CAUTION
● Petrol with standard EN 228 may be mixed
with small quantities of ethanol. However,
the so-called “bioethanol fuels” available at
commercial establishments with reference
E50 or E85, which contain a high percentage
of ethanol, may not be used, as they will
damage the fuel system.
● Even one tankful of leaded fuel would per-
manently impair the efficiency of the catalyt-
ic converter.
● High engine speed and full throttle can
damage the engine when using petrol with an
octane rating lower than the correct grade for
the engine. For the sake of the environment
Just one full tank of leaded fuel would seri-
ously impair the efficiency of the catalytic
converter. 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 thefuel 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 Au-
thorised Services, where information on how
to use them can also be obtained.
CAUTION
Do not refuel if the filler indicates that the
fuel contains metal. LRP (lead replacement
petrol) fuels contain high concentrations of
metal additives. Using them may damage the
engine! 159

Diesel Diesel* Diesel fuel
must conform to DIN EN 590 (EN =
“European Standard”). It must have a cetane
number (CN) of at least 51. The cetane num-
ber indicates the ignition quality of the diesel
fuel.
Notes on refuelling ››› page 158.
Biodiesel* CAUTION
● Your vehicle is not designed to use biodie-
sel fuel. Never, under any circumstances re-
fuel with biodiesel. The use of biodiesel fuel
could damage the engine and the fuel sys-
tem. The addition of biodiesel to diesel fuel
by the diesel manufacturer in accordance
with standard EN 590 or DIN 51628 is author-
ised and will not cause damage to the engine
or the fuel system.
● The diesel engine has been designed to be
used exclusively with diesel fuel conforming
to standard EN 590. Never refuel or use pet-
rol, kerosene, fuel oil or any other type of
fuel. If you accidentally fill up the vehicle
with the wrong type of fuel, do not start the
engine. Seek assistance from specialised per-
sonnel. The composition of these fuels may
severely damage the fuel system and the en-
gine. Winter operation
Winter-grade diesel
When using “summer-grade diesel fuel”, dif-
ficulties may be experienced at temperatures
below 0 °C (+32 °F) because the fuel thickens
due to wax separation. For this reason, “win-
ter-grade diesel fuel” is available in some
countries during the cold months. It can be
used at temperatures as low as -22 °C (-8 °F).
In countries with different climatic conditions
the diesel fuel generally sold has different
temperature characteristics. Check with the
Technical Services or filling stations in the
country concerned regarding the type of die-
sel fuels available.
Filter pre-heater
Your vehicle is fitted with a fuel filter glow
plug system, making it well equipped for op-
eration in winter. This ensures that the fuel
system remains operational to approx. -24 °C
(-11 °F), provided you use winter-grade diesel
which is safe to -15 °C (+5 °F).
However, if the fuel has waxed to such an ex-
tent that the engine will not start at tempera-
tures of under -24 °C (-11 °F), simply leave
the vehicle in a heated area for a while.
CAUTION
Do not mix fuel additives, the so-called “thin-
ners”, or similar additives with diesel fuel. LPG system (Liquefied
petroleum gas)*

Read carefully the instructions on how to use
the LPG pump.
Opening the fuel tank cap
The LPG filler neck is behind the fuel cap,
next to the petrol filler neck.
● The tank flap is located on the rear right-
hand side of the vehicle.
● Open the fuel tank flap.
Refuelling
● Remove the plug from the gas filler mouth
››› Fig. 140 1 .
● Screw the required adapter 2 onto the
LPG gas filler neck. ●
Refuel as indicated in the pump instruc-
tions.
● The fuel tank will be full when the pump
c ompr
essor automatically cuts the supply.
● If you wish to finish refuelling sooner, re-
lease the button on the pump to stop the
flow.
Closing the fuel tank cap
● Unscrew the adapter from the gas filler
neck 2 .
● Screw the cap onto the gas filler neck 1 .
● Close the fuel tank flap. The cover should
be flush with the bodywork. WARNING
Incorrect handling of LPG can cause explo-
sions, fire, serious burns and other injuries.
● LPG is a highly explosive and inflammable
substance.
● Small quantities of LPG may leak out after
refuelling. If LPG comes into contact with the
skin there is a risk of freezing. Note
● The vehicle includes one adapter for the
country in question, the most common one.
We generally recommend that you carry all
the adapters in your vehicle, as some coun-
tries use more than one type of filling sys-
tem. ●
If the outside temperature is very high, the
protection against overheating for the LPG
pump may disconnect automatically.
● If the outside temperature is very high, the
pressure of the LPG tank may be equal to or
greater than that of the gas tank of the LPG
pump. In this case, refuelling will be physi-
cally impossible.
● The filling nozzles of LPG pumps can differ
in the way they are operated. If you do not
know, ask a qualified employee at the petrol
station to do the refuelling.
● Noises heard when refuelling are normal
and do not indicate the presence of a fault in
the system. 161

Checking and refilling levels
LPG quality and consumption
Quality requirements for LPG are regulated
for all Europe in DIN EN 589 and permit the
use of LPG throughout Europe.
A difference is drawn between winter gas and
summer gas. Winter gas has a higher propor-
tion of propane gas. As a result, the driving
range of winter gas may be lower (due to in-
creased consumption) than that of summer
gas.
LPG supplier network
The number of LPG pumps is constantly in-
creasing.
Lists of existing LPG pumps may be found on
Internet.
LPG safety A series of collision tests performed on this
vehicle while running with LPG have con-
firmed its high level of safety.
The safety of the LPG system guarantees op-
eration without risk. The following safety
measures have been adopted:
● The LPG tank has a solenoid valve which
closes automatically when the engine is
switched off (ignition off) or when running on
petrol. ●
A solenoid type main valve disconnects the
supply of gas to the engine compartment
when the engine is switched off or running
on petrol.
● A safety valve in the LPG tank with pipes to
the outside prevents the gas from entering
the vehicle interior.
● All anchorage points and materials have
been designed to ensure the maximum pos-
sible levels of safety.
The condition of the LPG system should be
checked regularly to guarantee safe driving
conditions ››› . These checks are included
in the Maintenance Programme. WARNING
● If there is a smell of gas or a suspected
leak, stop the vehicle immediately and switch
off the ignition. Open the doors to ventilate
the vehicle. Do not carry on driving! Take the
vehicle to a specialised workshop and have
the fault repaired.
● Immediately extinguish any cigarettes and
remove from the vehicle any objects which
might produce a spark or cause a fire, and
switch off immediately if gas is smelt or a
leak is detected.
● LPG tanks are subject to pressure and must
be checked regularly. The owner of the vehi-
cle must check that these services are per-
formed correctly. ●
When parking the vehicle in a closed area
(e.g. in a garage), make sure that there is ad-
equate ventilation, either natural or mechani-
cal, to neutralise the LPG in the event of a
leak. Note
For any fault in the LPG system, please refer
to the SEAT web page, which lists the work-
shops authorised to repair these faults. Working in the engine

Advice
You should not do any work in the engine
compartment unless you know exactly how to
carry out the jobs and have the correct tools!
Have the work carried out by a specialised
workshop if you are uncertain.
All service fluids and consumables, e.g. cool-
ant, engine oil, spark plugs and batteries,
are under constant development. SEAT pro-
vides a constant flow of information to Tech-
nical Services concerning modifications. For
this reason, we recommend you have service
fluids and consumables replaced by a Techni-
cal Service. Please observe the relevant in-
structions ››› page 147 . The engine compart-
ment of
the vehicle is a hazardous area.
››› .
WARNING
All work on the engine or in the engine com-
partment, e.g. checking and refilling fluids,
involves the danger of injury and burns, acci-
dents and even fire.
● Never open the bonnet if you see steam,
smoke or coolant escaping from the engine
compartment. Otherwise, there is a risk of
sustaining burns. Wait until no more steam or
coolant is emitted, then allow the engine to
cool before carefully opening the bonnet.
● Switch off the engine and remove the key
from the ignition.
● Apply the handbrake and move the gear
lever to neutral or selector lever to position P.
● Keep children away from the vehicle. ●
Never touch hot engine parts. There is a
risk of burns.
● Never spill liquids on a hot engine or on a
hot exhaust gas system. This is a fire hazard.
● Avoid causing short-circuits in the electri-
cal system, particularly at the points where
the jump leads are attached ››› page 190. The
battery could explode.
● Never touch the radiator fan. It is tempera-
ture controlled and could start automatically,
even when the engine has been switched off
and the key removed from the ignition!
● Never cover the engine with additional in-
sulating materials such as a blanket. Risk of
fire!
● Do not unscrew the cap on the coolant ex-
pansion tank when the engine is hot. If the
coolant is hot, the cooling system will be
pressurised!
● Protect face, hands and arms by covering
the cap with a large, thick cloth to protect
against escaping coolant and steam.
● Always make sure you have not left any ob-
jects, such as cleaning cloths or tools, in the
engine compartment.
● If you have to work underneath the vehicle,
you must use suitable stands additionally to
support the vehicle, there is a risk of acci-
dent!. A hydraulic jack is insufficient for se-
curing the vehicle and there is a risk of injury.
● 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 the rotating parts, such as the drive belts, alternator, radiator fan, etc., and from
the high-voltage ignition system. You should
also observe the following:
– Never touch the electrical wiring of the
ignition system.
– Ensure that jewellery, loose clothing and
long hair do not get trapped in rotating
engine parts. Danger of death. Before
starting any work remove jewellery, tie
back and cover hair, and wear tight-fit-
ting clothes.
– Never accelerate with a gear engaged
without taking the necessary precau-
tions. The vehicle could move, even if the
handbrake is applied. Danger of death.
● If work has to be carried out on the fuel
system or on electrical components, you
must observe the following safety notes in
addition to the above warnings:
– Always disconnect the battery from the
on-board network. The vehicle must be
unlocked when this is done, otherwise
the alarm will be triggered.
– Do not smoke.
– Never work near naked flames.
– Always have a fire extinguisher on hand. CAUTION
When topping up service fluids, make sure
not to mistake them. Using the wrong fluids
could cause serious malfunctions and engine
damage! 164

Checking and refilling levels
For the sake of the environment
Service fluids leaks are harmful to the envi-
ronment. For this reason you should make
regular checks on the ground underneath
your vehicle. If you find spots of oil or other
fluids, have your vehicle inspected in a speci-
alised workshop. Opening the bonnet
