Checking and refilling levels
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 correspond-
ing engine compartment illustration ⇒ page 256.
Ensure the coolant conforms to the required specifications. Do not use a dif-
ferent type of additive if additive G 12++ is not available. 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.
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 additive G 12++ can be mixed with the G 12+ in any proportion.
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 199.
● 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
● If you notice a change in the colour of the liquid because it has been in
use for a long time, it is recommended to change it, as it will have lost some
of its properties and could cause damage to the vehicle.
● 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 cool-
ant 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.

Checking fluid levels
From time to time, the levels of the different fluids in the ve-
hicle must be checked. Never fill with incorrect fluids, other-
wise serious damage to the engine may be caused.
