Checking and refilling levels
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 ⇒
"Safety instructions on working in the engine compartment" on
page 188.
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 241.
Ensure the coolant conforms to the required specifications. Do not use a
different type of additive if G 12++ additive is not available. In this case use
only water and bring the coolant concentration back up to the correct level as
Fig. 128 In the engine
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
in
out of the cooling system when the engine is hot.
The G 12++ additive can be mixed with the G 12+ in any proportion.
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 188.
•
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.
