Checking and refilling

• Only our G12+ (purple colour) should be used as an antifreeze additive.
Observe the notice on the container. The cooling liquid may be purchased in
Technical Services.
• The antifreeze additive G12+ can be mixed with other additives (G11 and
G12).
• The additive G12 (red colour) should never be mixed with G11.

The level can only be checked properly when the engine is not
running.
The coolant level must be between the m m a a x x and m m i i n n marks on the
expansion tank when engine is cold and can be slightly above the
K
m m a a x x mark when it is warm.
Coolant losses
Coolant loss normally indicates leaks in the system. In this case
the cooling system should be checked by a Technical Service
Center without delay. It is not sufficient merely to add coolant.
In a sealed system losses can only occur if the boiling point of the
coolant is exceeded as a result of overheating, and coolant is
K
forced out of the system.
Topping up coolant
Switch engine off and let it cool down. Then cover expansion tank
cap with a cloth and turn cap carefully anti-clockwise and remove.

No other coolant may be used if G G 1 1 2 2 + + is not available. In this
case only water can be used and the correct mixture concentration
must be restored with the specified coolant additive (see previous
page) as soon as possible.
