Brake fluid
Checking the brake fluid level
The brake fluid is checked at the intervals given in the serv-
ice schedule.
Fig. 132 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 251. 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 63.
WARNING
Before opening the bonnet to check the brake fluid level, read and ob-
serve the warnings ⇒ page 193.

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 193 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 (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 194
⇒ 
in Warnings on handling the battery on page 207. For vehi-
cles with the battery under the spare wheel, open the rear lid
and lift the floor covering. The battery is located next to the
spare wheel.
– 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 251. The location of the battery in the luggage com-
partment can be seen in ⇒ Fig. 175.
The “magic eye” indicator, located on the top of the battery changes colour,
depending on the charge state and electrolyte level of the battery. 

210Checking 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 167.
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. 

217
If and when
If you have a puncture on one of the front wheels when using snow chains,
fit the compact temporary spare wheel in place of one of the rear wheels.
You can then attach the snow chains to the wheel taken from the rear and
use this wheel to replace the punctured front wheel.
WARNING
● The tyre pressures must be checked and corrected as soon as possi-
ble after fitting the temporary spare wheel.
● Do not drive faster than 80 km/h (50 mph). Higher speeds can cause
an accident.
● Avoid heavy acceleration, hard braking and fast cornering. Risk of ac-
cident.
● Never use more than one temporary spare wheel at the same time,
risk of accident.
● No other type of tyre (normal summer or winter tyre) may be fitted on
the compact temporary spare wheel rim.

Tyre repair kit*
The tyre repair kit (for vehicles not including a temporary
spare wheel) is stored under the floor panel in the luggage
compartment. In the event of a punctured tyre, your vehicle is equipped with the Tyre Mo-
bility System tyre repair kit.
The tyre repair kit consists of a container with sealing product to repair the
puncture and a compressor to generate the required tyre pressure. The kit
will reliably seal punctures up to a size of about 4 mm caused by the pene-
tration of a foreign body into the tyre.
Note
● Seek professional assistance if the repair of a tyre puncture is not possi-
ble with the sealing product. 
Wheel change Preparation work
What you must do before changing a wheel.
– If you have a flat tyre or puncture, park the vehicle as far away
from the flow of traffic as possible. Choose a location that is as
level as possible.
– All vehicle occupants should leave the vehicle. They should
wait in a safe area (for instance behind the roadside crash barri-
er).
– Switch the engine off. Switch the hazard warning lights on and
place the warning triangles in position.
– Apply the handbrake firmly.
– Engage the first gear , or put the selector lever to position P for
those vehicles with an automatic gearbox.
– If you are towing a trailer, unhitch it from your vehicle.
– Take the vehicle tools and the spare wheel out of the luggage
compartment. 

After changing the wheel there are still tasks to complete.
– Put the tools and jack back in the luggage compartment.
– Place the wheel with the defective tyre in the luggage compart-
ment and secure it.
– Check the tyre pressure of the newly fitted tyre as soon as pos-
sible.
– Have the tightening torque of the wheel bolts checked as soon
as possible with a torque wrench. The prescribed torque must
be 120 Nm.
Note
● If you notice that the wheel bolts are corroded and difficult to turn when
changing a wheel, they must be replaced before having the wheel bolt tight-
ening torque checked.
● For safety reasons, drive at moderate speeds until the wheel bolt tight-
ening torque has been checked. 
