How to clean the upholstery, trim fabrics and Alcantara ®
Cleaning the fabric on heated seats and electrically adjustable seats or
seats with airbag components
It is possible that there are important airbag components and electrical con-
nections inside the driver seat, passenger seat and possibly the outer rear
seats. If these seats and backrests are damaged, or are cleaned and are
treated incorrectly, or if they get wet, the vehicle electric system may be de-
stroyed and the airbag system damaged ⇒ 
.
Electric and heated seats contain components and electrical connections
that may be damaged if the seats are cleaned or incorrectly treated ⇒ 
.
Similarly, damage might be caused at other points in the vehicle's electric
system.
For this reason, bear the following indications in mind for cleaning:
● Do not use high-pressure or steam cleaning equipment or cold aerosols.
● Do not use cream detergents or detergent-based solutions for delicate
garments.
● Prevent the fabric from getting wet at all times.
● Only use cleaning products approved by SEAT.
● If in doubt, take the vehicle to a professional cleaning company.
Cleaning the fabric on unheated seats, non-electrically adjustable seats
and seats without airbag components
● Before using any cleaning products, consult and keep in mind the in-
structions of use, indications and warnings on the container.
● Use a vacuum cleaner (with the brush attachment) on the trim and seat
fabrics, the Alcantara ®
upholstery of the seats and the carpet.
● Do not use high-pressure or steam cleaning equipment or cold aerosols.
● For general cleaning, use a soft sponge or an ordinary lint-free microfi-
bre cloth ⇒ 
.
● Clean Alcantara ®
surfaces with a slightly damp cotton or woollen cloth,
or a standard lint-free microfibre cloth ⇒ 
. If the dirt on the trim and upholstery fabrics is only superficial, you can use
a standard foam cleaner.
If the upholstery and trim are very dirty, before cleaning them we recom-
mend you find out about the most suitable cleaning options from a profes-
sional cleaning company. If necessary, the cleaning should be carried out
by a specialised company.
Stain removal
When removing stains, it may be necessary to clean the whole surface and
not just the stain itself. Especially if the surface has been dirtied through
normal use. If you only clean the stained area, that part may then look light-
er than the rest. If in doubt, take the vehicle to a professional cleaning com-
pany.
WARNING
If there is a fault in the airbag system, it is likely that the airbag will not
deploy correctly, not deploy at all, or do so unexpectedly, which could
cause serious or fatal injuries.
● Have the system checked immediately by a specialised workshop.
CAUTION
If the upholstery on electrically operated seats or seats with airbag compo-
nents gets soaked, the vehicle's electric system and certain other compo-
nents may be damaged.
● If the seat gets soaked, take the vehicle immediately to a specialised
workshop to be dried and for the system components to be inspected.
● Do not use steam cleaning equipment as the dirt becomes more encrus-
ted and fixed in the material.
● High-pressure cleaning equipment and cold aerosols may damage the
upholstery. 

225
Vehicle maintenance and cleaning
CAUTION
● Brushes should only be used to clean the carpet and floor mats! Other
fabrics may be damaged if cleaned with a brush.
● If cream detergents or detergents for delicate garments are applied with
a damp cloth or sponge, they may, for example, leave rings when dry be-
cause of the tensioactive components they contain. Generally, such rings
are very difficult or almost impossible to remove.
CAUTION
● Do not let water soak into Alcantara ®
under any circumstances.
● Do not use leather cleaning products, solvents, wax polish, shoe cream,
stain removers or similar products on Alcantara ®
.
● Never use brushes for cleaning damp material as they could damage the
surface. 
Cleaning and maintenance of natural leather upholstery
Consult a professional cleaning workshop if you have any doubts on clean-
ing and maintaining the leather equipment in your car.
Maintenance and treatment
Nappa natural leather is delicate because it has no additional protective
layer.
● After cleaning, regularly apply a conditioner with sun-screen and im-
pregnating action. These products nourish the leather, soften it and make it
more breathable, as well as re-hydrating it. They also provide it with a pro-
tective film.
● Clean the leather every two or three months and remove stains as they
appear.
● Treat the leather regularly (about twice a year) with a suitable mainte-
nance product. ●
Apply as few cleaning and maintenance products as possible, always
using a dry, lint-free cotton or woollen cloth. Do not apply cleaning and
maintenance products directly to the leather.
● Remove recent ball-point pen and ink stains, lipstick, shoe cream and
similar stains as soon as possible.
● Maintain the colour of the leather. To do this, use a special cream espe-
cially coloured for leather to achieve the same overall colour, if necessary.
● Afterwards, go over it with a soft cloth.
Cleaning
SEAT recommends using a slightly damp cotton or woollen cloth for general
cleaning purposes.
Generally, the leather should never be soaked at any point, nor should wa-
ter penetrate the seams.
Before cleaning the leather upholstery, bear in mind the following recom-
mendations ⇒ page 224, Cleaning the fabric on heated seats and electrical-
ly adjustable seats or seats with airbag components.CAUTION
● On no account use solvents, wax polish, shoe cream, stain removers or
similar materials on leather.
● If the stain remains on the leather for long, it will soak in and be impos-
sible to remove.
● In the event of spilt liquids, dry immediately with an absorbent cloth to
prevent the liquid penetrating through the leather or seams.
● If the car is left standing in the sun for long periods, the leather should
be protected against direct sunlight to prevent it from fading.
Note
The leather will usually change colour slightly with use. 

Before opening the bonnet make sure that the windscreen wiper
arms are not lifted away from the glass. Otherwise the paint may
be damaged.
– Lift the bonnet slightly ⇒ 
.
– Press the release catch under the bonnet upwards ⇒ Fig. 179.
This will release the arrester hook under the bonnet.
– Open the bonnet.
The bonnet is held in position by a gas-filled strut.
WARNING
Never open the bonnet if you see steam or drips of coolant being re-
leased from the engine compartment. Failure to comply could result in
burns. Wait until no steam or coolant can be seen before opening the
bonnet.
 Work in the engine compartment
Extra caution is necessary when working on components in
the engine compartment.
Always be aware of the danger of injury and scalding as well as the risk of
accident or even fire when working in the engine compartment (e.g. when
checking and refilling fluids). Always observe the warnings listed below
and follow all general safety precautions. The engine compartment of the
vehicle is a potentially hazardous area ⇒ 
WARNING
● Switch the engine off.
● Remove the ignition key.
● Apply the handbrake firmly.
● If your vehicle is equipped with a manual gearbox, place the gear lev-
er in neutral. If you are driving an automatic vehicle, place the selector
lever in position P.
● Wait for the engine to cool down.
● Children should not be allowed to approach the engine compartment.
● Never spill liquids used for vehicle operation on the engine compart-
ment, as these may catch fire (e.g. coolant).
● Take care not to cause short circuits in the electrical system, especial-
ly when working on the battery.
● Never touch the radiator fan while the engine is hot, as the fan could
start up suddenly.
● Never open the expansion tank when the engine is hot. The cooling
system is under pressure.
● Protect face, hands and arms from any hot steam or hot coolant fluid
released by covering the cap with a large, thick rag when opening the ex-
pansion tank. 

238Checking and refilling levels
Topping up the engine oil 
Fig. 181 In the engine
compartment: Engine oil
filler cap
– Unscrew cap  from oil filler opening ⇒ Fig. 248.
– Carefully put in the specified grade of oil ⇒ page 236, adding
0.5 litres at a time.
– After two minutes, check the oil level once again ⇒ page 237.
– Where necessary, add more engine oil.
– Replace the oil filler cap carefully and push the dipstick all the
way in.
WARNING
● When refilling with oil, make sure no oil falls onto hot engine parts.
Failure to comply could result in fire.
● Wash your skin thoroughly if it comes into contact with engine oil.
CAUTION
● The oil level must never be above area a. This could damage the cata-
lytic converter or the engine. Contact a specialised workshop to drain the
engine oil if necessary.
● No additives should be used with engine oil. Any damage caused by the
use of such additives would not be covered by the factory warranty.
For the sake of the environment
● Oil must not be disposed of in the drain or on the ground.
● Always observe legal requirements when disposing of empty oil canis-
ters. 
Cooling system Engine coolant specifications
The engine cooling system is supplied from the factory with a specially trea-
ted mixture of water and, at least, 40 % of the additive G 13 (TLVW 774 J).
The engine coolant additive is recognisable by its purple colour. This mix-
ture of water and additive gives the necessary frost protection down to
-25°C (-13°F) and protects the light alloy parts of the cooling system against
corrosion. It also prevents scaling and considerably raises the boiling point
of the coolant.
To protect the engine cooling system, the percentage of additive must al-
ways be at least 40 %, even in warm climates where anti-freeze protection is
not required.
If greater frost protection is required in very cold climates, the proportion of
additive can be increased. However, the percentage of additive should not
exceed 60 %, as this would reduce the frost protection and, in turn, de-
crease the cooling capacity. 

239
Checking and refilling levels
When the coolant is topped up, use a mixture of distilled water and, at
least, 40 % of the G 13 or G 12 plus-plus (TL-VW 774 G) additive (both are
purple) to obtain an optimum anticorrosion protection ⇒ 
. The mixture of
G 13 with G 12 plus (TL-VW 774 F), G 12 (red) or G 11 (green-blue) engine
coolants will significantly reduce the anticorrosion protection and should,
therefore be avoided ⇒ 
.
WARNING
If there is not enough anti-freeze in the coolant system, the engine may
fail leading to serious damage.
● Please make sure that the percentage of additive is correct with re-
spect to the lowest expected ambient temperature in the zone in which
the vehicle is to be used.
● When the outside temperature is very low, the coolant could freeze
and the vehicle would be immobilised. In this case, the heating would
not work either and inadequately dressed passengers could die of cold.
CAUTION
The original additives should never be mixed with coolants which are not
approved by SEAT. Otherwise, you run the risk of causing severe damage to
the engine and the engine cooling system.
● If the fluid in the expansion tank is not purple but is, for example,
brown, this indicates that the G 13 additive has been mixed with an inade-
quate coolant. The coolant must be changed as soon as possible if this is
the case! This could result in serious faults and engine damage.
For the sake of the environment
Coolants and additives can contaminate the environment. If any fluids are
spilled, they should be collected and correctly disposed of, with respect to
the environment. Checking the coolant level
The coolant level can be checked visually.
Fig. 182 Engine com-
partment: Coolant fluid
deposit
– Switch the ignition off.
– Check the coolant level on coolant fluid expansion tank
⇒ Fig. 182. When the engine is cold, it should be between the
“min” and “max” marks. When the engine is hot, it may be
slightly above the “max” mark.
Its location is shown in the corresponding general overview of the engine
compartment.
The coolant level should be checked with the engine switched off.
The coolant level is monitored by a warning lamp on the instrument panel
display ⇒ page 81. However, we recommend that it should be checked oc-
casionally. 

Washer fluid and windscreen wiper blades Windscreen washer system
Plain water is not sufficient for the windscreen washer sys-
tem.
Fig. 183 In the engine
compartment: Cap of
windscreen washer fluid
reservoir.
The container for the windscreen washer contains the cleaning fluid for the
windscreen and the headlight washer system*. The container is located in
the engine compartment (front left). The filler cap is marked with the symbol
 ⇒ Fig. 183. The capacity of the container is listed in ⇒ page 304. Plain water on its own is not enough to clean the glass properly. It is there-
fore advisable to add a suitable washer fluid additive (with wax solvent) to
the water. A washer fluid with freeze-resistant additive should be used in
winter.
CAUTION
● Never put radiator antifreeze or other additives into the windscreen
washer fluid.
● Never use washer fluid which contains paint thinners or solvents as it
can damage the paintwork. 

Removing the wiper blade
–Lift the wiper arm away from the glass ⇒ Fig. 186
– Slide the blade adapter in the direction of the arrow and remove
the blade ⇒ Fig. 186.
Fitting the wiper blade
– With one hand, hold the top end of the wiper arm.
– Place the blade as shown in the ⇒ Fig. 187 and slide the adapt-
er along until it engages.
Check the condition of the wiper blade regularly. Change as required.
If the windscreen wiper scrapes, it should be replaced if damaged, or
cleaned if soiled.
If this is not sufficient, refer to a specialised workshop.
WARNING
Do not drive unless you have good visibility through all windows!
● Clean the windscreen wiper blades and all windows regularly.
● The wiper blades should be changed once or twice a year.
CAUTION
● A damaged or dirty window wiper could scratch the rear window.
● Never use fuel, nail varnish remover, paint thinner or similar products to
clean the window.
● Never move the windscreen wiper by hand. This could cause damage. Brake fluid
Checking the brake fluid level
The brake fluid level can be checked visually.
Fig. 188 Engine com-
partment: markings on
brake fluid reservoir
The brake fluid level must be between the “Min” and “Max” ⇒ Fig. 188
markings.
The fluid level may drop slightly after a period of time due to the automatic
compensation for brake pad wear. This is quite normal.
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. If the fluid level in
the reservoir is too low, this will be indicated by the brake warning lamp
⇒  page 73 and
⇒ page 80. If this should happen,
take the vehicle to a spe-
cialised workshop immediately and have the brake system inspected. 

A highly explosive mixture of gases is released when the bat-
tery is under charge.
Keep children away from acid and batteries!
WARNING
Always be aware of the danger of injury and chemical burns as well as
the risk of accident or fire when working on the battery and the electrical
system:
● Wear eye protection. Protect your eyes, skin and clothing from acid
and particles containing lead.
● Battery acid is very corrosive and caustic. Wear protective gloves and
eye protection. Do not tilt the batteries. This could spill acid through the
vents. Rinse battery acid from eyes immediately for several minutes with
clear water. Then seek medical care immediately. Neutralise any acid
splashes on the skin or clothing with a soapy solution, and rinse off with
plenty of water. If acid is swallowed by mistake, consult a doctor immedi-
ately.
● Fires, sparks, open flames and smoking are prohibited. When han-
dling cables and electrical equipment, avoid causing sparks and electro-
static 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 en-
gine, 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.
WARNING (Continued)
● Deactivate the anti-theft alarm by unlocking the vehicle before you
disconnect the battery! The alarm 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 re-
verse 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 which
has frozen. A flat battery can also freeze at temperatures close to 0°C.
● Ensure that the vent hose is always connected to the battery.
● Never use a defective battery. This could cause an explosion. Replace
a damaged battery immediately.
CAUTION
● Never disconnect the battery if the ignition is switched on or if the en-
gine is running. This could damage the electrical system or electronic com-
ponents.
● 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 freezing. If it freezes it will be damaged. 
Charging the battery
