the coolant during operation will be approx-

imately 130 †.

The antifreeze/corrosion inhibitor concentra-

tion in the engine cooling system should:

R

be at least 50%. This will protect the engine

cooling system against freezing down to

approximately -37 †.

R

not exceed 55% (antifreeze protection

down to -45 †). Heat will otherwise not be

dissipated as effectively.

If the vehicle has lost coolant, top it up with

equal amounts of water and antifreeze/cor-

rosion inhibitor.

Mercedes-Benz recommends an antifreeze/

corrosion inhibitor concentrate in accord-

ance with MB Specifications for Service Prod-

ucts 310.1.

i

When the vehicle is first delivered, it is fil-

led with a coolant mixture that ensures

adequate antifreeze and corrosion protec-

tion.

i

The coolant is checked at every mainte-

nance interval at a qualified specialist

workshop.

WARNING

Windscreen washer concentrate is highly

flammable. If it comes into contact with hot

engine components or the exhaust system it
