– If the level is underneath the “MIN” mark, top up with coolant.
To p p i n g u p c o o l a n t
–Only use new coolant.
– 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 corresponding
engine compartment diagram ⇒page 270.
Make sure that the coolant meets the required specifications ⇒page 215.
Do not use a different type of additive if coolant additive G 12+ is not avail-
able. 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 215.
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 G 12+ (dyed purple) may be mixed with G 12 (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 208.
•
When the engine is warm or hot, th e 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 col our of G 12 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 has been lost, wait for the engine to cool down before
putting in cold coolant. This avoid s damaging the engine. Large coolant
losses are an indication of leaks in the cooling system. See a specialised
workshop immediately and have the cooling system checked. Otherwise,
there is a risk of engine damage.WARNING (continued)

The water for cleaning the windscreen should always be
mixed with washer fluid.The windscreen washer and the headlight washing system are supplied with
fluid from the windscreen washer fluid container in the engine compartment.
The reservoir is located on the right-hand side of the engine compartment.
Plain water is not enough to clean th e windscreen and headlights. We recom-
mend that you always add a product to the windscreen washer fluid.
Approved windscreen cleaning products exist on the market with high deter-
gent and anti-freeze properties, thes e 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 208.Caution

If this is not sufficient, refer to a qualified 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 fluidChecking the brake fluid level
The brake fluid is checked at the intervals given in the service
schedule.– Read 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 engine
compartment diagram ⇒page 270. 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.

Checking and refilling levels
222However, 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 instru-
ment panel will warn you if the brake fluid level is too low ⇒page 72.
WARNING
Before opening the bonnet to check the brake fluid level, read and observe
the warnings ⇒page 208.Changing the brake fluid
The brake fluid must be renewed every two years.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 208 in
“Working in the engine compartment”.
Brake fluid absorbs moisture. In the cour se 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.
For this reason the brake fluid must be renewed every two years.
It is important that you use only use brake fluid compliant with the 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
observe the warnings ⇒page 208.
•
Brake fluid should be stored in the closed original container in a safe
place out of reach of children. There is a toxic risk.
•
Have the brake fluid changed every two years at the latest. Heavy use
of the brakes may cause a vapour lock if the brake fluid is left in the system
for too long. This would seriously affect the efficiency of the brakes and the
safety of the vehicle. This may cause an accident.Caution
Brake fluid could damage the paintwork. Wipe off any brake fluid from the
paintwork immediately.
For the sake of the environment
Brake fluid must be drained and disposed of in the proper manner observing
environmental regulations.

BatteryWarnings on handling the battery
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. Neutralize 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, naked lights and smoking are prohibited. When handling
cables and electrical equipment, avoid causing sparks and electrostatic 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
engine, 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 alar m will otherwise be triggered.
•
When disconnecting the battery from the vehicle electrical system,
disconnect first the negative ca ble 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
reverse 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 that 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 may be fatally explosive. Replace a
damaged battery immediately.Caution
•
Never disconnect the battery if the ignition is switched on or if the engine
is running. This could damage the electrical system or electronic compo-
nents.
•

Checking and refilling levels
224•
If the vehicle is left standing in cold conditions for a long period, protect
the battery from frost. 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 bonnet and open the battery cover at the front ⇒ in
“Safety instructions on working in the engine compartment” on
page 208 ⇒ in “Warnings on handling the battery” on
page 223.
– 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 270.
The round window (“magic eye”) on the top of the battery changes colour,
depending on the charge level and electrolyte level of the battery.
If the colour in the window is colourless or bright yellow, the electrolyte level
of the battery is too low. Have the battery checked by a qualified workshop.
The colours green and black are used by the workshops for diagnostic
purposes.
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
periods, the battery should be checked by a qualified 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 qualified 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 spec-
ifications of your vehicle.
WARNING
•
We recommend you use only maintenance-free or cycle free leak-proof
batteries that comply with the 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 223.

– 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 pr otected by fuses. The fuses are located
behind a cover at the left-hand end of the dash panel and on the left-hand
side of the engine compartment.
The electric windows are protected by circuit breakers. These reset automat-
ically after a few seconds when the overload (caused for example by frozen
windows) has been corrected.
Colour coding of fuses
WARNING
Never “repair” damaged fuses and never replace them with fuses with a
higher rating. Failure to comply could re sult in fire. This could also cause
damage to other parts of the electrical system.
Note
•
If a newly replaced fuse blows again after a short time, the electrical
system must be checked by a qualified workshop as soon as possible.
•
If you replace a fuse with a stronger fuse, you could cause damage to
another location in the electrical system.
•
Always keep some spare fuses in the vehicle. These are available from
SEAT dealers.
