Therefore, do not use more than this amount of anticorrosion/antifreeze. If the coolant level is low, water and MB anticorrosion/ antifreeze should be used to bring it up to the proper level (have cooling system checked for signs of leakage). The water in the cooling system must meet minimum requirements, which are usually satisfied by normal drinking water. If your are not sure about the water quality, consult your authorized Mercedes-Benz Center. Anticorrosion/antifreeze Your vehicle contains a number of aluminium parts. The use of aluminium components in motor vehicle engines necessitates that anticorrosion/antifreeze coolant used in such engines be specifically formulated to protect the aluminium parts.
