Other coolant additives can lead to
considerable reduction in corrosion
protection.
The resulting corrosion damage can
lead to coolant loss and subse-
quently to major engine damage.
Important note
Please observe the following when
topping off:
Never mix G12 with other coolant
additives (including not with G11).
You can recognise the G12 from its
red colour. If the liquid is brown,
G 12 has been mixed with another
coolant!
In this case, the coolant must be
changed immediately!
Otherwise serious malfunctions or
engine damage may occur!
Important
Observe the safety precautions
beginning on page 17 before
