Checking and refilling levels
Topping up coolant
– Only use new coolant liquid.
– 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 correspond-
ing engine compartment illustration ⇒ page 259.
Ensure the coolant conforms to the required specifications. Do not use a dif-
ferent type of additive if additive G 12++ is not available. 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.
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 additive G 12++ can be mixed with the G 12+ in any proportion.
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 200.
● When the engine is warm or hot, the cooling system is pressurised!
Do not unscrew the cap on the coolant expansion tank when the engine
is hot. This is a burn injury risk.
CAUTION
● If you notice a change in the colour of the liquid because it has been in
use for a long time, it is recommended to change it, as it will have lost some
of its properties and could cause damage to the vehicle.
● If a lot of coolant fluid has been lost, wait for the engine to cool down
before putting in cold coolant. This avoids damaging the engine. Large cool-
ant losses are an indication of leaks in the cooling system. See a special-
ised workshop immediately and have the cooling system checked. Other-
wise, there is a risk of engine damage. 

The windscreen washer and the headlight washers are supplied with fluid
from the windscreen washer fluid container in the engine compartment. The
container holds approx. 2 litres; in vehicles with headlight washers* it holds
approx. 4.5 litres.
The tank is in the engine compartment.
Plain water is not enough to clean the windscreen and headlights. We rec-
ommend that you always add a product to the windscreen washer fluid. Ap-
proved windscreen cleaning products exist on the market with high deter-
gent and anti-freeze properties, these may be added all-year-round. Please
follow the dilution instructions on the packaging.
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 200.
CAUTION
● Never put radiator anti-freeze or other additives into the windscreen
washer fluid.
● Always use approved windscreen cleansing products diluted as per in-
structions. If you use other washer fluids or soap solutions, the tiny holes in
the fan-shaped nozzles could become blocked. Changing windscreen wiper blades
If the windscreen wiper blades are in perfect condition, you
will benefit from an improved visibility. Damaged wiper
blades should be replaced immediately.

Checking and refilling levels
To change the blades it is necessary to change the rest position of
the wipers to the service position.
Do not change the windscreen wipers when out of the service posi-
tion, as it could cause paint to flake off the bonnet due to friction
with the windscreen wiper arm.
Service position (For changing wiper blades)
– Ensure that the wiper blades are not frozen.
– Turn ignition on and off and then (before approx. 9 sec.) move
the windscreen wiper lever to the intermittent wipe position.
The windscreen wipers will move to the service position
⇒ Fig. 137.
Removing the wiper blade
– Lift the windscreen wiper arm.
– Press on the securing tab ⇒ Fig. 138.
– Extract the wiper blade from the wiper arm.
Fitting the wiper blade
– Insert the wiper blade onto the windscreen wiper arm until it
clicks into place.
– Place the windscreen wiper arms to their initial position.
If the windscreen wipers smear , they should be replaced if they are dam-
aged, or cleaned if they are soiled.
If this does not produce the desired results, the setting angle of the wind-
screen wiper arms might be incorrect. They should be checked by a special-
ised workshop and corrected if necessary.
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
● Damaged or dirty windscreen wipers could scratch the windscreen.
● Never use fuel, nail varnish remover, paint thinner or similar products to
clean the windows. This could damage the windscreen wiper blades.
● Never move the windscreen wiper or windscreen wiper arm manually.
This could cause damage.
● To avoid damage to the bonnet and the windscreen wiper arms, the lat-
ter should only be lifted off the windscreen when in service position.
Note
● The windscreen wiper arms can be moved to the service position only
when the bonnet is properly closed.
● You can also use the service position, for example, if you want to fix a
cover over the windscreen in the winter to keep it clear of ice. 

Brake fluid Checking the brake fluid level
The brake fluid is checked at the intervals given in the serv-
ice schedule.
Fig. 141 In the engine
compartment: Brake fluid
reservoir cover
– Read off 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 en-
gine compartment illustration ⇒ page 259. 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
instrument panel will warn you if the brake fluid level is too low ⇒ page 65.
WARNING
Before opening the bonnet to check the brake fluid level, read and ob-
serve the warnings ⇒ page 200.

Changing the brake fluid
The Maintenance Programme indicates the brake fluid
change intervals. We recommend that you have the brake fluid changed by a Technical Serv-
ice.
Before opening the bonnet, please read and follow the warnings ⇒ 
in
Safety instructions on working in the engine compartment on page 200 in
section “Safety notes for 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.
Be sure to always use the correct brake fluid. Only use brake fluid that ex-
pressly meets VW 501 14 standards.
You can buy VW 501 14 standard brake fluid in a SEAT dealership or SEAT
Official Service. If none is available, use only high quality brake fluid that
meets DIN ISO 4925 CLASS 4 standards, or USA Standards FMVSS 116 DOT
4.
Using any other kind of brake fluid or one that is not of a high quality may
affect operation of the brake system and reduce its effectiveness. Never use
a brake fluid if the container does not state that it complies with VW 501 14,
DIN ISO 4925 CLASS 4 standards, or USA standards FMVSS 116 DOT 4. 

WARNING
Brake fluid is poisonous. Old brake fluid impairs the braking effect.
● Before opening the bonnet to check the brake fluid level, read and ob-
serve the warnings ⇒ page 200.
● Brake fluid should be stored in the closed original container in a safe
place out of reach of children. There is a toxic risk.
● Complete the brake fluid change according to the Maintenance Pro-
gramme. Heavy use of the brakes may cause a vapour lock if the brake
fluid is left in the brake system for too long. This would seriously affect
the effectiveness of the brakes and the safety of the vehicle. This may
cause an accident.
CAUTION
Brake fluid damages the vehicle paintwork. Wipe off any brake fluid from
the paintwork immediately.
For the sake of the environment
The brake pads and brake fluid must be collected and disposed of accord-
ing the applicable regulations. The SEAT Technical Service network has the
necessary equipment and qualified personnel for collecting and disposing
of this waste material. Vehicle battery

WARNING (Continued)
● 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.
● 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 on-board network,
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 freeze at temperatures around 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.
● For vehicles with the battery in the luggage compartment: Check that
the battery gas ventilation hose is securely attached.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. 
Checking the electrolyte level
The electrolyte level should be checked regularly in high-
mileage vehicles, in hot countries and in older batteries. – Open the engine bonnet and the battery cover ⇒ 
in Safety in-
structions on working in the engine compartment on page 201
⇒ 
in Warnings on handling the battery on page 214.
– 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 shown in the corresponding engine compart-
ment diagram ⇒ page 259.
The “magic eye” indicator, located on the top of the battery changes colour,
depending on the charge state and electrolyte level of the battery.
There are two different colours: 
Safety FirstOperating InstructionsPractical TipsTechnical Specifications

216Checking and refilling levels
● Black: correct charge status.
● Transparent/clear yellow: the battery must be replaced. Contact a speci-
alised workshop. 
Charging and changing the vehicle battery
The battery is maintenance-free and is checked during the
inspection service. All work on the vehicle battery requires
specialist knowledge.
If you often drive short distances or if the vehicle is not driven for long peri-
ods, the battery should be checked by a specialised workshop between the
scheduled services.
If the battery has discharged and you have problems starting the vehicle,
the battery might be damaged. If this happens, we recommend you have
the vehicle battery checked by a Technical Service where it will be re-charg-
ed or replaced.
Charging the battery
The vehicle battery should be charged by a specialised workshop only, as
batteries using special technology have been installed and they must be
charged in a controlled environment.
Replacing a vehicle battery
The battery has been developed to suit the conditions of its location and
has special safety features.
Genuine SEAT batteries fulfil the maintenance, performance and safety
specifications of your vehicle.
WARNING
● We recommend you use only maintenance-free or cycle free leak-proof
batteries which comply with standards T 825 06 and VW 7 50 73. This
standard applies as of August 2001.
● Before starting any work on the batteries, you must read and observe
the warnings ⇒ 
in Warnings on handling the battery on page 214.
For the sake of the environment
Batteries contain toxic substances such as sulphuric acid and lead. They
must be disposed of appropriately and must not be disposed of with ordi-
nary household waste. 
Wheels
General notes
Avoiding damage
– If you have to drive over a kerb or similar obstacle, drive very
slowly and at a right angle.
– Keep grease, oil and fuel off the tyres.
– Inspect the tyres regularly for damage (cuts, cracks or blisters,
etc.). Remove any foreign objects embedded in the treads.
Storing tyres
– When you remove the tyres, mark them in order to maintain the
same direction of rotation when they are installed again. 

217
Checking and refilling levels
– When removed, the wheels and/or tyres should be stored in a
cool, dry and preferably dark location.
– Store tyres in a vertical position if they are not fitted on wheel
rims.
New tyres
New tyres must 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 vehicle pulling to one side, this may indicate that one of
the tyres is damaged. The tyres should be checked immediately by a Techni-
cal Service.
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 during the first 500 km
(300 miles). Drive particularly carefully to avoid possible accidents.
● Never drive with damaged tyres. This may cause an accident.
● If you notice unusual vibrations or if the vehicle pulls to one side
when driving, stop the vehicle immediately and check the tyres for dam-
age.
 Checking tyre pressure
The correct tyre pressure can be seen on the sticker on the
inside of the fuel tank flap.
1. Read the required tyre inflation pressure from the sticker. The values refer to Summer tyres.
2. The tyre pressures should only be checked when the tyres are cold. The slightly raised pressures of warm tyres must not be re-
duced.
3. Adjust the tyre pressure to the load you are carrying.
Tyre pressure
The correct tyre pressure is especially important at high speeds. The pres-
sure 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. 

Tyre useful life
The useful life of tyres is dependent on tyre pressure, driving
style and fitting.
Fig. 142 Tyre tread wear
indicators
Fig. 143 Diagram for
changing wheels Wear indicators
The original tyres on your vehicle have 1.6 mm high “tread wear indicators”
⇒ Fig. 142, running across the tread. Depending on the make, there will be
6 to 8 of them evenly spaced around the tyre. Markings on the tyre sidewall
(for instance the letters “TWI” or other symbols) indicate the positions of
the tread wear indicators. The minimum tread depth required by law is
1.6 mm (measured in the tread grooves next to the tread wear indicators).
Worn tyres must be replaced. Different figures may apply in export countries
⇒ 
.
Tyre pressure
Incorrect tyre pressure causes premature wear and could cause tyre blow-
out. For this reason, the tyre pressure should be checked at least once per
month ⇒ page 217.
Driving style
Fast cornering, heavy acceleration and hard braking all increase tyre wear.
Changing wheels around
If the front tyres are worn considerably more than the rear ones it is advisa-
ble to change them around as shown ⇒ Fig. 143. The useful life of all the
tyres will then be about the same time.
Wheel balance
The wheels on new vehicles are balanced. However, various factors encoun-
tered in normal driving can cause them to become unbalanced, which re-
sults in steering vibration.
Unbalanced wheels should be rebalanced, as they otherwise cause exces-
sive wear on steering, suspension and tyres. A wheel must also be reba-
lanced when a new tyre is fitted.
Incorrect wheel alignment
Incorrect wheel alignment causes excessive tyre wear, impairing the safety
of the vehicle. If tyres show excessive wear, you should have the wheel
alignment checked by a Technical Service. 
