MaintenanceMaintenance and care

The antifreeze/corrosion inhibitor
concentration in the engine cooling system
should:
R
be at least 50 %. This will protec tthe engine
cooling system against freezing down to
approximately -35 ‡ (-37 †).
R not exceed 55 % (antifreeze protection
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 inhibito rconcentrate in
accordance with MB Specifications for
Service Products 310.1.
The coolant is checked with every
maintenance interval at a qualified specialist
workshop.
i When the vehicle is first delivered, it is
filled with a coolant mixture that ensures
adequate antifreeze and corrosion
protection.
