To change the blades it is necessary to change the rest position of 
the wipers to the service position.
Service position (For changing wiper blades)
– Ensure that the wiper blades are not frozen.
– Turn ignition on and off and then (before approx. 8 seconds have elapsed), move the windscreen wiper lever to the intermittent 
wipe position. The windscreen wi pers will move to the service 
position.
Changing the windscreen wiper blades
– Lift the wiper arm away from the windscreen.
– Push the side buttons, free the blade and pull in the direction of  the arrow  ⇒fig. 164.
Fitting the wiper blade
– Insert a blade of identical length and design into the wiper arm.
– Slide the blade until it clicks into position.
– Push the wiper arms back against the windscreen.The windscreen wiper arms return to their original position when the ignition 
is turned on and the windscreen wiper  lever is operated, or when driving 
faster than 6 km/h.
If the  windscreen wipers smear , they should be replaced if they are damaged, 
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 qualified 
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 
bonnet is properly closed.

Checking and refilling levels
226Brake fluidChecking the brake fluid level
The brake fluid is checked at the intervals given in the service 
schedule.– 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 engine 
compartment diagram ⇒ 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 noticeab
ly 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 73.
WARNING
Before opening the bonnet to check the brake fluid level, read and observe 
the warnings  ⇒page 213.Changing the brake fluid
The Maintenance Program 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 213 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 consider ably 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 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 213.
•
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 
Program. 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 batter ies. 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 smoki ng are prohibited. When handling 
cables and electrical equipment, avoid causing sparks and electrostatic 
WARNING (continued)
Wear eye protection
Battery acid is very corrosive and caustic. Wear protective 
gloves and eye protection!
Fires, sparks, naked lights and smoking are prohibited!
A highly explosive mixture of gases is released when the 
battery is under charge.
Keep children away from acid and batteries!

228charge. 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 alarm will otherwise be triggered.
•
When disconnecting the battery from the vehicle electrical system, 
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 
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 which 
has frozen. A flat battery can freeze at temperatures around 0°
•
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.
•
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 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 213  ⇒ in “Warnings on handling the battery” on 
page 227.
– 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 show n in the corresponding engine compart-
ment diagram  ⇒page 273.
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.
