Caution
Cleaning products which contain solvents will damage the material.Cleaning wooden trim*– Clean the wooden trim with a clean cloth moistened with water.
– If this does not provide satisfactory results, use a gentle soap
solution.
CautionCleaning products which contain solvents will damage the material.Cleaning cloth seat covers and fabric trimCloth seat covers and fabric trim on the doors, headlining etc. can be cleaned
with a special interior cleanser or with dry foam and a soft brush.Cleaning leather*Normal cleaning
– Moisten a cotton or woollen cloth with water and wipe over the leather surfaces. Cleaning stubborn stains
– More stubborn dirt can be removed using a mild soap solution
(pure liquid soap; two tablespoons diluted in one litre of water)
and a cloth.
– Do not let the water soak through the leather or soak into the seams.
– Then wipe off with a soft, dry cloth.
Leather care
– The leather should be treated regularly (about twice a year) with a special leather-care product, which is available from your
Authorised Service Centre.
– Apply these products very sparingly.
– Then wipe off with a soft, dry cloth.
SEAT does everything possible to preserve the special qualities of leather, as
a natural product. Because of the natural properties of the specially selected
hides employed, the finished leather has a certain sensitivity to grease and
dirt, etc. so a degree of care is required in everyday use and when looking
after the leather.
Dust and grit in the pores and seams can scratch and damage the surface. If
the vehicle is left standing in the sun for long periods, the leather should be
protected against direct su nlight to prevent it from fading. However, slight
colour variations in high-quality natural leather are normal.
Caution
•
Do not use solvents, wax polish, shoe cream, spot removers or similar
products on leather.

Tips and Maintenance
Te c h n i c a l D a t a
Accessories, parts replacement and modificationsAccessories and partsAlways consult an Authorised Service Centre before
purchasing accessories and parts.Your vehicle is designed to offer a high standard of active and passive safety.
Before purchasing accessories and parts, and before making technical
changes to your car, we recommend that you consult your Authorised Service
Centre.
SEAT dealerships will be happy to provide you with the latest information
about the use, legal requirements and recommendations from the manufac-
turer regarding accessories and parts.
We recommend you use only SEAT Approved Accessories
® and SEAT
Approved Spare Parts
®. This way, SEAT can guarantee that the product in
question is suitable, reliable and safe. Authorised Service Centres have the
necessary experience and facilities to ensure that parts are installed correctly
and professionally.
Despite continuous observation of the market, SEAT is not able to assess the
reliability, safety and suitability of parts not approved by SEAT. For this reason
SEAT cannot assume responsibility for any non-genuine parts used, even if
these parts have been approved by an official testing agency or are covered
by an official approval certificate.
Any equipment subsequently installed which has a direct effect on the
vehicle and/or the way it is driven (e.g. cruise control system or electronically-
controlled suspension) must be approved by SEAT for use in your vehicle and
bear the e mark (the European Union's authorisation symbol).
If any additional electrical components are fitted which do not serve to
control the vehicle itself (for instance a refrigerator box, laptop or ventilator fan, etc.), these must bear the
CE mark (European Union manufacturer
conformity declaration).
WARNING
Accessories, for example telephone holders or drink holders, should never
be fitted on the covers of, or within the working range of, the airbags. If
they are, there is a danger of resulting injury if the airbag is triggered in an
accident.ModificationsModifications must always be carried out according to our
specifications.Unauthorised modifications to the electr onic components or software in the
vehicle may cause malfunctions. Due to the way the electronic components
are linked together in networks, other systems may be affected by the faults.
This can seriously impair safety, lead to excessive wear of components, and
also invalidate your vehicle registration documents.
SEAT Authorised Service Centres cannot be held liable for any damage
caused by modifications and/or work performed incorrectly.
For this reason, we recommend that all work should be performed by an
Authorised Service Centre using genuine and SEAT
® approved parts and
accessories .

Checking and refilling levels
196
− Never fill the spare fuel canister inside the vehicle or on it. An elec-
trostatic charge could build up during filling, causing the fuel fumes to
ignite. This may be fatally explosive. Always place the canister on the
ground to fill it.
− Insert the fuel nozzle into the mouth of the canister as far as
possible.
− If the spare fuel canister is made of metal, the filling nozzle must be
in contact with the canister during filling. This helps prevent an electro-
static charge building up.
− Never spill fuel in the vehicle or in the luggage compartment. Fuel
vapours are explosive. Danger of death.Caution
•
Fuel spills should be removed from the paintwork immediately.
•
Never run the tank completely dry. An irregular fuel supply could cause
misfiring. As a result, unburnt fuel could enter the catalytic converter and
cause damage.For the sake of the environment
Do not try to put in more fuel after the automatic filler nozzle has switched off;
this may cause the fuel to overflow if it becomes warm.
PetrolPetrol types
The correct petrol types are listed on a sticker inside the fuel
tank flap.Only unleaded petrol, corresponding to the standard DIN EN 228, may be
used for vehicles with catalytic converters (EN = “European Norm”).
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. However, this
has no advantage in terms of fuel consumption and engine power.
Caution
•
Even one full tank of leaded fuel would permanently impair the efficiency
of the catalytic 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 seriously impair the efficiency of the
catalytic converter.Petrol additives
Petrol additives improve the quality of the petrol.The quality of the petrol influences running behaviour, performance and
service life of the engine. For this reason you should use good quality petrol

containing additives. These additives will help to prevent corrosion, keep the
fuel system clean and prevent deposits from building up in the engine.
If good quality petrol with additives is
not available or engine problems occur,
the required additives must be added during refuelling.
DieselDiesel*Diesel fuel must correspond to DIN EN 590 (EN = “European standard”). It
must have a cetane number (CN) of at least 51. The cetane number indicates
the ignition quality of the diesel fuel.
Notes on filling with fuel ⇒page 195.RME fuel*
Only those vehicles fitted with special equipment (number PR
2G0 for biodiesel use) may use biodiesel corresponding to
the standard DIN EN 14214.The biodiesel fuel must comply wit h the DIN EN 14.214 (FAME) Standard.•
Biodiesel is a methylester obtained from rapeseed oil.
•
DIN is a German abbreviation for “Deutsches Institut für Normung e.V.”,
the German standards institute.
•
EN means European Norm.
•
FAME is the English abbreviation “ Fatty Acid Methyl Ester” If the date sticker of the vehicle in
cludes the number PR 2G0 optional equip-
ment) this means that that vehicle has been prepared for biodiesel use.
Your Authorised Service Centre or automobile association will be able to
advise on where you can obtain RME biodiesel fuel.
Your Authorised Service Centre can also be consulted to know if the vehicle
has been prepared for biodiesel use.
Things to note about RME fuel (biodiesel)
•
The performance of a vehicle using biodiesel maybe somewhat reduced.
•
Fuel consumption of a vehicle using biodiesel may be slightly higher.
•
RME fuel can be used in winter at temperatures down to approx. -10°C.
•
At outside temperatures below -10°C, we recommend using winter diesel
fuel.Caution
•
RME fuel can damage the fuel system in vehicles that are not suitably
adjusted.
•
If you decide to use biodiesel in your vehicle, please use only RME fuel
which is DIN E 14,214 compliant.
•
If you use biodiesel that does not me et the required standard, the fuel
filter could become clogged.Note
•
In case of low exterior temperatures and a biodiesel fuel percentage of
higher than 50%, an increase in gas emission may occur during operation of
the independent heating.
•
The fuel filter may become clogged when fuel is changed to biodiesel. For
this reason, we recommend that, about every 300 or 400 km, following a fuel
change, also change the fuel filter. Also. note the instructions in the inspec-
tion and maintenance plan.

Note
Before a long trip, we recommend finding an engine oil that conforms to the
corresponding VW specifications and keeping it in the vehicle. This way, the
correct engine oil will always be available for a top-up if needed.Checking the engine oil level
The engine oil dipstick indicates the level of the oil.Before opening the bonnet, read and observe the warnings ⇒ in
“Safety instructions on working in the engine compartment” on
page 198.
– Park the vehicle on an even surface.
– After stopping the engine, wait a few minutes for the oil to drain back into the sump. – Raise the bonnet
⇒page 200.
– Pull out the dipstick.
– Wipe the dipstick with a cloth and insert it again, pushing it in as far as it will go.
– Pull the dipstick out again and check the oil level ⇒fig. 144.
– Replace the dipstick, pushing it in as far as it will go.
The position of the dipstick is shown in the corresponding engine compart-
ment diagram ⇒page 260.
If the oil level is in area ⇒fig. 144 , do not top up with oil.
If the oil level is in area , you may top up with oil (approx. 0.5 l).
If the oil level is in area , you must top up with oil (approx. 1.0 l).
It is normal for the engine to consum e a certain amount of oil. Consumption
can be up to 1.0 litres per 1,000 km. For this reason the engine oil level must
be checked at regular intervals, preferably when filling the tank and before a
journey.
When the engine is working hard, for instance during sustained high-speed
motorway cruising in summer, when towing a trailer or climbing on mountain
passes, the oil level should preferably be kept within area and not above
this.
WARNING
Any work carried out in the engine compartment or on the engine must be
carried out cautiously.•
When working in the engine compartm ent, always observe the safety
warnings ⇒page 198.

CautionIf the oil level is above the area do not start the engine. This could result
in damage to the engine and catalytic converter. Contact an Authorised
Service Centre.Topping up engine oil

Top up gradually with small quantities of oil.Before opening the bonnet, read and observe the warnings ⇒ in
“Safety instructions on working in the engine compartment” on
page 198.
– Unscrew cap from oil filler opening ⇒ fig. 145.
– Top-up oil in small amounts, using the correct oil. – To avoid over-filling with engine oil, you should top-up using
small quantities, wait a while and check the oil level before
adding any more oil.
– As soon as the oil level is in area , carefully close the cap.
The position of the oil filler opening is shown in the corresponding engine
compartment diagram ⇒ page 260.
Engine oil specification ⇒page 201.
WARNING
Oil is highly inflammable! Ensure that no oil comes into contact with hot
engine components when topping up.
Caution
If the oil level is above the area do not start the engine. This could result
in damage to the engine and catalytic converter. Contact a qualified work-
shop.
For the sake of the environment
The oil level must never be above area . Otherwise oil can be drawn in
through the crankcase breather and escape into the atmosphere via the
exhaust system.

– If the level is underneath the “MIN” mark, top up with coolant.
To p p i n g u p c o o l a n t
–Only use new coolant.
– Do not fill above the “MAX” mark.
Closing the coolant expansion tank
–Screw the cap on again tightly .The position of the coolant expansion reservoir is shown in the corresponding
engine compartment diagram ⇒page 260.
Make sure that the coolant meets the required specifications ⇒page 205.
Do not use a different type of additive if coolant additive G 12+ is not avail-
able. In this case use only water and bring the coolant concentration back up
to the correct level as soon as possible by putting in the specified additive
⇒ page 205.
Always top up with new coolant.
Do not fill above the “MAX” mark. Otherwise the excess coolant will be forced
out of the cooling system when the engine is hot.
The coolant additive G 12+ (dyed purple) may be mixed with G 12 (dyed red)
and also with G 11.
WARNING
Any work carried out in the engine compartment or on the engine must be
carried out cautiously.•
When working in the engine compartment, always observe the safety
warnings ⇒ page 198.
•
When the engine is warm or hot, th e cooling system is pressurised! Do
not unscrew the cap on the expansion tank when the engine is hot. This is
a burn injury risk.Caution
•
When mixed with other additives the col our of G 12 will change to brown.
If this occurs you should have the coolant changed immediately. Failure to do
so will result in engine damage!
•
If a lot of coolant has been lost, wait for the engine to cool down before
putting in cold coolant. This avoid s damaging the engine. Large coolant
losses are an indication of leaks in the cooling system. See a specialised
workshop immediately and have the cooling system checked. Otherwise,
there is a risk of engine damage.WARNING (continued)

Brake fluidChecking the brake fluid level
The brake fluid is checked at the intervals given in the service
schedule.– Read the fluid level at the transparent brake fluid reservoir. It
should always be between the “MIN” and “MAX” marks.The position of the brake fluid reservoir is shown in the corresponding engine
compartment diagram ⇒page 260. The brake fluid reservoir has a black and
yellow cap.
The brake fluid level drops slightly when the vehicle is being used as the
brake pads are automatically adjusted as they wear. However, if the level goes down noticeably in a short time, or drops below the
“MIN” mark, there may be a leak in the brake system. A display on the instru-
ment panel will warn you if the brake fluid level is too low
⇒page 72.
WARNING
Before opening the bonnet to check the brake fluid level, read and observe
the warnings ⇒ page 198.Changing the brake fluid
The brake fluid must be renewed every two years.We recommend that you have the brake fluid changed by an Authorised
Service Centre.
Before opening the bonnet, please read and follow the warnings ⇒ in
“Safety instructions on working in the engine compartment” on page 198 in
“Working in the engine compartment”.
Brake fluid absorbs moisture. In the course of time, it will absorb water from
the ambient air. If the water content in the brake fluid is too high, the brake
system could corrode. This also considerably reduces the boiling point of the
brake fluid. Heavy use of the brakes may then cause a vapour lock which
could impair the braking effect.
For this reason the brake fluid must be renewed every two years.
It is important that you use only use brake fluid compliant with the US
standard FMVSS 116 DOT 4. We recommend the use of Genuine SEAT brake
fluid.
WARNING
Brake fluid is poisonous. Old brake fluid impairs the braking effect.

charge. Never short the battery terminals. High-energy sparks can cause
injury.
•
A highly explosive mixture of gases is released when the battery is
under charge. The batteries should be charged in a well-ventilated room
only.
•
Keep children away from acid and batteries.
•
Before working on the electrical system, you must switch off the
engine, the ignition and all consumers. The negative cable on the battery
must be disconnected. When a light bulb is changed, you need only switch
off the light.
•
Deactivate the anti-theft alarm by unlocking the vehicle before you
disconnect the battery! The alar m will otherwise be triggered.
•
When disconnecting the battery from the vehicle electrical system,
disconnect first the negative cable and then the positive cable.
•
Switch off all electrical consumers before reconnecting the battery.
Reconnect first the positive cable and then the negative cable. Never
reverse the polarity of the connections. This could cause an electrical fire.
•
Never charge a frozen battery, or one which has thawed. This could
result in explosions and chemical burns. Always replace a battery that has
frozen. A flat battery can freeze at temperatures around 0°C.
•
Ensure that the vent hose is always connected to the battery.
•
Never use a defective battery. This may be fatally explosive. Replace a
damaged battery immediately.Caution
•
Never disconnect the battery if the ignition is switched on or if the engine
is running. This could damage the electrical system or electronic compo-
nents.
•
Do not expose the battery to direct sunlight over a long period of time, as
the intense ultraviolet radiation can damage the battery housing.
•
If the vehicle is left standing in cold conditions for a long period, protect
the battery from frost. If it “freezes” it will be damaged.
Checking the electrolyte level
The electrolyte level should be checked regularly in high-
mileage vehicles, in hot countries and in older batteries.– Open the bonnet and open the battery cover at the front ⇒ in
“Safety instructions on working in the engine compartment” on
page 198 ⇒ in “Warnings on handling the battery” on
page 212.
– Check the colour display in the "magic eye" on the top of the battery.
– If there are air bubbles in the window, tap the window gently until they disperse.The position of the battery is show n in the corresponding engine compart-
ment diagram ⇒page 260.
The round window (“magic eye”) on the top of the battery changes colour,
depending on the charge level and electrolyte level of the battery.
If the colour in the window is colourless or bright yellow, the electrolyte level
of the battery is too low. Have the battery checked by a qualified workshop.
The colours green and black are used by the workshops for diagnostic
purposes.

New tyres
New tyres have to be run-in
⇒page 173.
The tread depth of new tyres may vary, according to the type and make of tyre
and the tread pattern.
Concealed damage
Damage to tyres and rims is often not readily visible. If you notice unusual
vibrations or the car pulling to one side, this may indicate that one of the tyres
is damaged. The tyres should be chec ked immediately by an Authorised
Service Centre.
Tyres with directional tread pattern
An arrow on the tyre sidewall indicates the direction of rotation on tyres with
directional tread. Always observe the direction of rotation indicated when
fitting the wheel. This guarantees optimum grip and helps to avoid aqua-
planing, excessive noise and wear.
WARNING
•
New tyres do not have maximum grip in the first 500 km. Drive particu-
larly carefully to avoid risk of accident.
•
Never drive with damaged tyres. This may cause an accident.
•
If you notice unusual vibration or if the vehicle pulls to one side when
driving, stop the vehicle immediately and check the tyres for damage.
Checking tyre pressure
The correct tyre pressure can be seen on the sticker on the
inside of the tank flap.1. Read the required ty re inflation pressure from the sticker. The
values refer to Summer tyres. For Winter tyres, you must add 0.2
bar to the values given on the sticker.
2. The tyre pressures should only be checked when the tyres are cold. The slightly raised pressures of warm tyres must not be
reduced.
3. Adjust the tyre pressure to the load you are carrying.Tyre pressure
The correct tyre pressure is especially important at high speeds. The pressure
should therefore be checked at least once a month and before starting a
journey.
WARNING
A tyre can easily burst if the pressure is too low, causing an accident!•
At continuously high speeds, a tyre with insufficient pressure flexes
more. In this way it becomes too hot, and this can cause tread separation
and tyre blow-out. Always observe the recommended tyre pressures.
•
If the tyre pressure is too low or too high, the tyres will wear prema-
turely and the vehicle will not handle well. Risk of accident!For the sake of the environment
Under-inflated tyres will increase fuel consumption.
