h eat transfer ca pa bil ity of th e sol ution. Therefore, d o 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 aluminum parts. The
use of aluminum components in motor vehicle engines
necessitates that anticorrosion/antifreeze coolant used
in such e ng ines b e specif ica lly formul ated to protec t th e
aluminum parts. (Failure to use such anticorrosion/
antifreeze coolant will result in a significantly
shortened service life).
Therefore the following product is strongly
recommended for use in your car: Mercedes-Benz
Anticorrosion/Antifreeze Agent.Before the start of the winter season (or once a year in
the hot southern regions), you should have the
anticorrosion/antifreeze concentration checked. The
coolant is also regularly checked each time you bring
your vehicle to your authorized Mercedes-Benz Center
for service.
