Comply with the important safety notes for ser-vice products when handling coolant(Ypage 358).
The coolant is a mixture of water and anti-freeze/corrosion inhibitor. It performs the fol-lowing tasks:
Ranti-corrosion protection
Rantifreeze protection
Rraising the boiling point
If the coolant has antifreeze protection down to-35 ‡ (-37 †), the boiling point of the coolantduring operation is approximately 266 ‡(130 †).
The antifreeze 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 not bedissipated as effectively
Mercedes-Benz recommends an antifreeze/corrosion inhibitor concentrate in accordancewith MB Specifications for Service Products310.1.
iWhen the vehicle is first delivered, it is filledwith a coolant mixture that ensures adequateantifreeze and anti-corrosion protection.
iThe coolant is checked with every mainte-nance interval at a qualified specialist work-shop.

Windshield washer system
Important safety notes
GWARNING
Windshield washer concentrate is highly flam-
mable. 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 use washer fluid which is suitable forlamp lenses, e.g. MB SummerFit or MB Win-terFit. Unsuitable washer fluid may damagethe lamp lenses of the headlamps.
!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 the impor-tant safety notes on service products(Ypage 358).
At temperatures above freezing:
XFill the washer fluid reservoir with a mixture ofwater and windshield washer fluid, e.g. MBSummerFit.
Add 1 part MB SummerFit to 100 parts water.
At temperatures below freezing:
XFill the washer fluid reservoir with a mixture ofwater and washer fluid, e.g. MB WinterFit.
For the correct mixing ratio refer to the infor-mation on the antifreeze reservoir.
iAdd windshield washer fluid, e.g. MB Sum-merFit or MB WinterFit, to the washer fluid allyear round.
