•Never pour oil down drains or into the ground.•Use a suitable container when draining the used oil. It must be large
enough to hold all the engine oil.CoolantCoolant specifications
Coolant is a mixture of water and at least 40% coolant addi-
tive.The cooling system must be filled with a mix ture of water and at least 40 % of
our coolant additive G12+ or an additive with the specification TT-VW 774 F (it
is dyed purple). This mixture provides the necessary freeze protection down
to -25 °C and protects the alloy parts of the cooling system against corrosion.
It also prevents scaling and raises the boiling point of the coolant.
The concentration of coolant must always be at least 40% - even if freeze
protection is not required.
If greater freeze protection is required in very cold climates, the proportion of
the antifreeze additive G12+ can be increased. However, the percentage of
coolant additives should not exceed 60%, as this would reduce the freeze
protection. It would also reduce the cooling effect. A mixture with 60% addi-
tive will give antifreeze protection to approx. -40 °C.
WARNING
•The coolant additive is toxic. There is a toxic risk. Always keep the
coolant additive in the original container which should be stored out of the
reach of children. The same applies to coolant which you have drained off.
•The coolant additive G12+ must be added in sufficient quantities to
provide anti-freeze protection at th e coldest ambient temperatures that
can be expected. At extremely cold outside temperatures, the coolant could
freeze, causing the vehicle to breakdown. As the heater would not work
either, there is a risk of freezing to death.Caution
•Other additives may give considerably inferior corrosion protection. The
resulting corrosion in the cooling system can lead to a loss of coolant,
causing serious damage to the engine.•The coolant additive G12+ (purple) can be mixed with the additive G12
(red) or G11. Never mix G12 (red colour) with G11.WARNING (continued)

Checking and refilling levels
240Checking the coolant level and topping up

The correct coolant level is important for fault-free func-
tioning of the engine cooling system.Before opening the bonnet, read and observe the warnings ⇒ in
“Safety instructions on working in the engine compartment” on
page 232.
Opening the coolant expansion tank
– Switch off the engine and allow it to cool.
– To prevent scalding, cover the cap on the expansion tank with a
thick cloth and carefully unscrew the cap ⇒.
Checking coolant level
– Look into the open coolant expansion tank and read off the coolant level. – If the level is below the “MIN” mark, top up with coolant.
Topping up coolant
–Only use new
coolant liquid.
– 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 illustration ⇒page 291.
Make sure that the coolant meets the required specifications ⇒page 239.
Do not use a different type of additive if coolant additive G12+ 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 239.
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 G12+ (dyed purple) may be mixed with G12 (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 232.

•When the engine is warm or hot, the 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 colour of G12 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 fluid has been lost, wait for the engine to cool down
before putting in cold coolant. This avoids damaging the engine. Large
coolant losses are an indication of leaks in the cooling system. See a special-
ised workshop immediately and have the cooling system checked. Other-
wise, there is a risk of engine damage.
Washer fluid and windscreen wiper bladesTopping up washer fluid
Y
The water for cleaning the windscreen should always be
mixed with washer fluid.The windscreen washer and the headlight washers 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 the 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, these may be added all-year-round. Please
follow the dilution instructions on the packaging.
