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 G 12+ (purple) can be mixed with the additive G 12
(red) or G 11. Never mix G12 (red colour) with G 11.
Checking 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 Ÿ in
“Safety instructions on working in the engine compartment” on
page 209 .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 Ÿ .
Checking coolant level
– Look into the open coolant expansion tank and read off the
coolant level.
– If the level is underneath the “MIN” mark, top up with coolant.
Topping up coolant
–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 Ÿpage 262.
Make sure that the coolant meets the required specifications Ÿpage 216.
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
Ÿpage 216.
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.

Checking and refilling levels 218
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 Ÿpage 209
•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 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 avoids 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.
Washer fluid and windscreen wiper blades
Topping up washer fluid Y
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 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.

Checking fluid levels
From time to time, the levels of the different fluids in the
vehicle must be checked. Never fill with incorrect fluids, to do
so may cause serious damage to the engine.
