Comply with the important safety notes forservice products when handling coolant(Ypage 334).
The coolant is a mixture of water and corro-sion inhibitor/antifreeze concentrate. It per-forms the following tasks:
Ranti-corrosion protection
Rantifreeze protection
Rraising the boiling point
If the coolant has antifreeze protection downto -35 ‡ (-37 †), the boiling point of the cool-ant during operation is approximately 266 ‡(130 †).
Theantifreeze concentrate/corrosion inhibitorconcentration in the engine cooling systemshould:
Rbe at least 50%. This will protect the enginecooling system against freezing down toapproximately -35 ‡(-37 †)
Rnot exceed 55% (antifreeze protection downto -49 ‡ [-45 †]). Otherwise, heat will notbe dissipated as effectively
Mercedes-Benz recommends a coolant or cor-rosion inhibitor/antifreeze concentrate inaccordance withMB Specifications for Service Products 310.1.
iWhen the vehicle is first delivered, it is fil-led with a coolant mixture that ensures ade-quate antifreeze and anti-corrosion protec-tion.
iThe coolant is checked with every mainte-nance interval at a qualified specialist work-shop.

Important safety notes
GWARNING
Windshield washer concentrate is highly
flammable. If windshield washer concentrate
gets onto hot components of the engine or
the exhaust system, it can ignite. There is a
risk of fire and injury.
Make sure that windshield washer concen-
trate is not spilled in the vicinity of the filler
neck.
!Only MB SummerFit and MB WinterFitwasher fluid should be mixed together. Thespray nozzles may otherwise becomeblocked.
Do not use distilled or de-ionized water. Other-wise, the level sensor may give a false reading.
When handling washer fluid, observe theimportant safety notes on service products(Ypage 334).
At temperatures above freezing:
XFill the washer fluid reservoir with a mixtureof water and windshield washer fluid, e.g.MB SummerFit.
Add 1 part MB SummerFit to 100 parts water.
At temperatures below freezing:
XFill the washer fluid reservoir with a mixtureof water and washer fluid, e.g. MB WinterFit.
For the correct mixing ratio refer to theinformation on the antifreeze reservoir.
iAdd windshield washer fluid, e.g. MB Sum-merFit or MB WinterFit, to the washer fluidall year round.
