cooling system against freezin gd own to
approximately -35 ‡( -37 †).R
not exceed 55% (antifreez ep rotection down
to -49 ‡[ -45 †]). Otherwise, heat will not be
dissipated as effectively
If the vehicle has lost coolant, add equal
amounts of water and antifreeze/corrosion
inhibitor.
Mercedes-Benz recommends an antifreeze/
corrosion inhibitor concentrate in accordance
with MB Specifications for Servic eP roducts
310.1.
