• 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.
K
Checking coolant level
The level can only be checked properly when the engine is not
running.
The coolant level must be between the
m ma
ax
xand m
mi
in
nmarks on the
expansion tank when engine is cold and can be slightly above the
m ma
ax
xmark when it is warm.K
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
forced out of the system.
K
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

+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.
