The antifreeze and corrosion inhibitor con-
centration in the cooling system should:
! be at least 50%. This will pro tect the
cool ing sy stem against freezing down
to approximately –37 °C.
! not exceed 55% (antifreeze protection
down to –45 °C), since the heat is then
not dissipated as effectively.
If the vehicle has lost coolant, top it up with
equal parts of water and an antifreeze and
corrosion inhibitor. Mercedes-Benz recom-
mends that you use an antifreeze and cor-
rosion inhibitor which has been approved
for Mercedes-Benz.
! The co oling system has a permanent supply
which must be renewed after 15 years or
250,000 km at the most.
Merc edes-Be nzrecommends that you use an an-
tifreeze and cor rosion inhibitor which has been
appr oved for Mercedes-Benz. Over a period of time, the brake fluid ab-
sorbs moisture from the air; this reduces
its boiling point.
