Checking and refilling levels
Changing the front 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.
Fig. 148 Changing the
front wiper blades
Changing wiper blades can be done in both the rest and horizontal
positions. Ensure that the wiper blades are not frozen.
Changing the windscreen wiper blades
– Lift the wiper arm away from the windscreen.
– Press on the side tabs A
and release the blade moving it in the
direction of the arrow 1 ⇒ fig. 148.
Fitting the wiper blade
– Insert the tab 2
into the slot 3 of the blade
⇒ fig. 148. –
Move the blade towards the arm in the opposite direction of the
arrow 1
,until it clicks into position
⇒ fig. 148.
– Push the wiper arms back against the windscreen.
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.
● Do not pull the windscreen wipers forward unless they are in the service
position. Otherwise the bonnet could be damaged.
Note
● The wiper arms can be moved to the service position only when the bon-
net is properly closed. 

Checking and refilling levels
Brake fluid Checking the brake fluid level
The brake fluid is checked at the intervals given in the serv-
ice schedule.
Fig. 151 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 273. 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.
WARNING
Before opening the bonnet to check the brake fluid level, read and ob-
serve the warnings ⇒ page 217.

Changing the brake fluid
The Maintenance Programme indicates the brake fluid
change intervals. 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 217 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.
It is important that you use only brake fluid compliant with 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.
● Before opening the bonnet to check the brake fluid level, read and ob-
serve the warnings ⇒ page 217. 

234Wheels 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 184.
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. 

Switch off the ignition and the component concerned.
– Identify the fuse corresponding to the damaged electric con-
sumer ⇒ page 252.
– Take the plastic clip from inside the fuse cover, fit it onto the
blown fuse and pull the fuse out.
– Replace the blown fuse (which will have a melted metal strip)
with a new fuse of the same ampere rating.
Fuse cover in engine compartment
– Switch off the ignition and its failed electrical component.
– Prise off the fuse cover in the engine compartment by pressing
the tabs towards the centre of the cover ⇒ fig. 161.
– Identify the fuse for the failed component ⇒ page 252.
– Take the plastic clip from inside the fuse cover (at left-hand end
of the dash panel), fit it onto the blown fuse and pull the fuse
out.
– Replace the blown fuse (which will have a melted metal strip)
with a new fuse of the same ampere rating.
– Carefully fit the fuse cover back on to ensure no water can enter
the fuse box.
The individual electrical circuits are protected by fuses. The fuses are loca-
ted behind a cover at the left-hand end of the dash panel and on the left-
hand side of the engine compartment. 
