234The cooling system is filled at the factory with the correct amount of anti-
freeze for the country concerned.
In most cases, the mixture consists of 60% water and 40% antifreeze . This
mixture gives the required antifreeze protection at temperatures down to
-25 °C and particularly protects the metal parts of the cooling system against
corrosion. It also prevents scaling and significantly raises the boiling point of
the coolant fluid.
Countries with warm climate
The coolant fluid concentration must not be reduced by adding plain water,
even in the summer or in warm climates. The concentration of the antifreeze
must always be at least 40%.
Countries with cold climate
If greater freeze protection is required in very cold climates, the proportion of
G12++ antifreeze can be increased. A concentration of 60% offers antifreeze
protection of temperatures down to approx. -40 °C. However, the concentra-
tion of antifreeze must not exceed 60% , as the antifreeze protection would
then drop and the performance of the coolant system would suffer.
Vehicles for countries with cold climates (e.g. Sweden, Norway and Finland)
have factory-filled antifreeze protection for temperatures down to -35 °C. In
these countries, the concentration of antifreeze should always be at least
50%.
Caution
•It is advisable to have the cooling system checked before the winter
season to make sure that the antifreeze concentration is adequate for the
conditions to be expected. This applies particularly if you intend to take the
vehicle into a colder climate zone. If necessary, have the antifreeze concen-
tration increased to 50 - 60% as required.•Use only G12++ antifreeze, an additive meeting the “TL-VW 774G” spec-
ification. Other antifreezes may give considerably inferior corrosion protec- tion. The damage caused by the use of these antifreezes may lead to a loss of
coolant fluid, causing serious damage to the engine.
•G12++ antifreeze can be mixed only with antifreeze additives G11, G12
and G12+.Checking the coolant level
The coolant level can be checked visually.– Switch the ignition off.
– Check the coolant level on coolant fluid expansion tank ⇒fig. 179 . When the engine is cold, it should be between the
“min” and “max” marks. When the engine is hot, it may be
slightly above the “max” mark.Its location is shown in the corresponding general overview of the engine
compartment.

236Radiator fan
The radiator fan can start running spontaneously.The auxiliary fan can continue to run for as long as 10 minutes after stopping
the engine, even after the ignition is switched off. It may also start running
suddenly ⇒ after some while if•Stored heat raises the coolant temperature, or•The hot engine compartment is additionally heated up by the sun.WARNING
When working in the engine compartment be aware that the radiator fan
may start running suddenly, leading to the risk of injury.
Washer fluid and windscreen wiper bladesWindscreen washer system
Plain water is not sufficient for the windscreen washer
system.The container for the windscreen washer contains the cleaning fluid for the
windscreen and the headlight washer system*. The container is located in the
engine compartment (front left). The fi ller cap is marked with the symbol
W
⇒ fig. 180.
The capacity of the container is listed in ⇒page 301.
Plain water on its own is not enough to clean the glass properly. It is therefore
advisable to add a suitable washer fluid additive (with wax solvent) to the
water. A washer fluid with freeze-resistant additive should be used in winter.

Removing the wiper blade
– Lift the wiper arm away from the glass ⇒page 239, fig. 183
– Slide the blade adapter in the direction of the arrow and remove the blade ⇒page 239, fig. 183 .
Fitting the wiper blade
– With one hand, hold the top end of the wiper arm.
– Place the blade as shown in the ⇒page 239, fig. 184 and slide
the adapter along until it engages.Check the condition of the wiper blade regularly. Change as required.
If the windscreen wiper scrapes , it should be replaced if damaged, or
cleaned if soiled.
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 level can be checked visually.The brake fluid level must be between the “Min” and “Max” ⇒ fig. 185 mark-
ings.
The fluid level may drop slightly after a period of time due to the automatic
compensation for brake pad wear. This is quite normal.
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. If the fluid level in the
reservoir is too low, this will be indicated by the brake warning lamp
⇒ page 70 and ⇒ page 77. If this should happen, take the vehicle to a qual-
ified workshop immediately and have the brake system inspected.

Safety First
Operating Instructions
Practical Tips
Technical Specifications
•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 °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.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.
Charging the battery
A fully-charged battery is important for reliable starting.–Note the warnings ⇒ in “Important safety warnings for
handling a vehicle battery” on page 242 and ⇒.
– Switch off the ignition and all electrical equipment.
– Only if fast-charging: both battery cables must be disconnected (first the negative cable, then the positive cable).
– Connect the charger cables to the battery terminals, noting the colour code (red = positive; black or brown = negative).
– Now connect the battery charger to the power socket and switch on.
– After charging the battery: switch off the battery charger and disconnect the power point cable.
– Finally disconnect the charger cables from the battery.
– If necessary, reconnect both battery cables to the battery (first the positive cable, then the negative cable).When charging with a low current (for instance with a small battery charger)
the battery does not normally have to be disconnected. However, both
battery cables must be disconnected before fast-charging the battery with a
high current. However, always follow the instructions given by the manufac-
turer of the battery charger.
The fast-charging procedure for a battery is dangerous ⇒ in “Important
safety warnings for handling a vehicle battery” on page 242, as it requires a
special charger and the corresponding level of knowledge. We therefore
recommend that this work should only be performed by a qualified workshop.
