Corrosion protection/antifreeze agents are hazardous for the environment.
When handling these materials, always make sure that the corrosion protec-
tion/antifreeze agents do not enter the environment, but are disposed of in a manner
compatible to the environment.
Always make sure of sufficient antifreeze and only use corrosion protection/antifreeze
agents expressly permitted according to Mercedes-Benz factory standards 325.5 or
326.5. (See Page 516)
