Checking and refilling levels
218However, 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 73.
WARNING
Before opening the bonnet to check the brake fluid level, read and observe
the warnings ⇒page 205.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 205 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.
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 205.
•
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. Th is 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 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.

Wear eye protection

Battery acid is very corrosive and caustic. Wear protective
gloves and eye protection!

Checking and refilling levels
220•
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 205 ⇒ in “Warnings on handling the battery” on
page 219.
– 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 263.
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 which 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 219.
