238Checking and refilling levels
Opening the coolant expansion tank
–Switch off the engine and allow it to cool.
– To prevent scalding, cover the cap on the expansion tank with a
thick cloth and carefully unscrew the cap ⇒ 
.
Checking coolant level
– Look into the open coolant expansion tank and read off the
coolant level.
– If the level is below the “MIN” mark, top up with coolant.
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 287.
Make sure that the coolant meets the required specifications ⇒ page 237.
Do not use a different type of additive if additive G12+ 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
⇒  page 237.
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 G12+ (dyed purple) may be mixed with G12 (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 230.
● When the engine is warm or hot, the 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 colour of G12 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 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. 

Removing the wiper blade
–Lift the wiper arm away from the glass ⇒ fig. 169
– Slide the blade adapter in the direction of the arrow and remove
the blade ⇒ fig. 169.
Fitting the wiper blade
– With one hand, hold the top end of the wiper arm.
– Place the blade as shown in the ⇒ fig. 170 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 is checked at the intervals given in the serv-
ice schedule.
Fig. 171 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 287. 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 77.

Checking and refilling levels
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 230
⇒ 
in Warnings on handling the battery on page 244.
– 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 287.
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:
● Black: correct charge status.
● Transparent/clear yellow: the battery must be replaced. Contact a spe-
cialist 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 an Authorised Service Centre where it will be
re-charged 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 2001.
● Before starting any work on the batteries, you must read and observe
the warnings ⇒ 
in Warnings on handling the battery on page 244. 

248Wheels and 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.
The sticker with the tyre pressure values can be found on the inside of the
tank flap. The tyre pressure values given are for cold tyres. Do not reduce
the slightly raised pressures of warm tyres ⇒ 
.
WARNING
● Check the tyre pressure at least once per month. Checking the tyre
pressure is very important. If the tyre pressure is too high or too low,
there is an increased danger of accidents - particularly at high speeds.
● 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 pressure monitoring
The tyre pressure monitoring system constantly checks the
pressure of the tyres.
The system uses the speed sensors of the ABS wheels. It operates by analy-
sing the speed and frequency spectrum of each wheel.
For optimum performance, use genuine SEAT tyres. In addition, check and
adjust tyre pressures regularly.
Whenever the tyre pressures are changed or one or more tyres are changed,
the system should be Reset by pressing the SET switch on the centre con-
sole.
The system warns the driver in the event of a loss of pressure by means of
symbols and messages in the instrument panel display. The system uses
ESC (ESP) ⇒ page 196.
Note that tyre pressure also depends on tyre temperature. Tyre pressure in-
creases about 0.1 bar for each 10 °C in tyre temperature increase. The tyre
heats up while the vehicle is being driven and the tyre pressure will rise ac-
cordingly. For this reason, you should only adjust the tyre pressures when
they are cold (i.e. approximately at ambient temperature).
To ensure that the tyre pressure monitoring system works reliably, you
should check and, if necessary, adjust the tyre pressures at regular intervals
and store the correct pressures (reference values) in the system.
A tyre pressure information label is attached to the inside of the fuel tank
flap. 

Wheels and tyres
Run-flat tyres
Run-flat tyres allow you to continue driving even with a
punctured tyre, in the majority of cases.
In vehicles that are factory-fitted with run-flat tyres 1)
the loss of tyre
pressure is indicated on the instrument panel.
Driving with run-flat tyres (emergency running)
– Leave the ESC (ESP)/ASR (TCS) (Electronic Stability Control) acti-
vated, or activate it ⇒ page 195.
– Continue driving carefully and slowly (80 km/h maximum).
– Avoid sudden manoeuvres and sharp turns.
– Avoid driving over obstacles (for example kerbs) or potholes.
– Look out for the ESC (ESP)/ASR (TCS) intervening often, smoke
coming from the tyres or the smell of rubber, the vehicle vibrat-
ing or a clattering noise. If any of these occur, stop the vehicle.
The run-flat tyres have a tag on the side of the tyre, with the description:
“DSST”, “Eufonia”, “RFT”, “ROF”, “RSC”, “SSR” or “ZP”.
The sides of this type of tyre are reinforced. When the tyres lose air they are
supported on the sides (emergency driving).
The loss of pressure in the tyre is shown on the instrument panel. You can
then drive a maximum of 80 km and if the circumstances are favourable (for
example, low load), even more.
The damaged tyre should be changed as soon as possible. The rim should
be checked in a specialist workshop to detect possible damage and replace it if necessary. We recommend you contact Technical Service. If more than
one tyre is being used under emergency conditions, this reduces the dis-
tance which can be travelled.
Starting driving in emergency conditions
When loss in tyre pressure is displayed on the instrument panel, this means
that at least one tyre is being driven in emergency conditions
⇒ 
.
End of emergency operation
Do not drive on if:
● smoke is coming from one of the tyres,
● there is a smell of rubber,
● the vehicle vibrates,
● there is a rattling noise.
When is it no longer possible to continue driving even using run-flat tyres?
● If one of the tyres has been severely damaged in an accident, etc. If a
tyre has been badly damaged there is a risk that parts of the tread can be
thrown off and cause damage to the fuel lines, brake pipes or fuel filler.
● It is also advisable to stop driving if severe vibrations occur, or if the
wheel starts overheating and gives off smoke.
WARNING
When driving in emergency conditions, the driving quality of the vehicle
is considerably impaired.
● The maximum permitted speed of 80 km/h is subject to road and
weather conditions. Please observe legal requirements when doing so.
● Avoid sharp turns and rapid manoeuvres, and brake earlier than usu-
al. 
