NOTES
An engine filled with type 30 antifreeze must not be filled later on with conventional coolant as per Specification 325.0 or 325.2. Type 30 antifreeze may not  be mixed with other antifreezes and it must  be replaced every 3 years  !
Engine damage can occur otherwise.
IMPORTANT A special antifreeze (type 30) is available for the "light alloy corrosion in cooling circuit" repair case. Indications of light alloy corrosion in the cooling circuit are: 
  • Sludging or gel formation in cooling system
  • Engine overheating
  • Flow rate deficiency in cooler

In these cases, a warning label (model 30) is to be attached in a well-visible spot on the coolant expansion reservoir.
IMPORTANT Use antifreeze model 30 if warning label (model 30) is present on the coolant expansion reservoir.
IMPORTANT ENGINE 207, 212
Do (2) not  fill the coolant expansion reservoir to the lower edge of the marking bar only, because at extremely low outside temperatures it is possible that the instrument cluster will briefly display a coolant level message.
The coolant expansion reservoir (2) may be filled when warm or cold to the lower edge of the filler neck  .
IMPORTANT Use approved anti-corrosion and antifreeze agents only.
