Comply with the important safety notes for ser-
vice products when handlin g coolant
(
Ypage 378).
The coolant isa mixture of water and ant i-
freeze/corrosion inh ibitor. It is responsible for
the foll owing:
RAnti-corrosion protection
RAntifreeze protection
RRaisin g the boiling point
If the coolant has antifreeze protection downto
-35 ‡ (-37 †), the boilingpoin t of the coolant
during operation is approximately 266 ‡
(130 †).
The antifreeze concentrate /corrosion inh ibitor
concentration inthe engine co oling system
should:
Rbe at least 50 %.This willprotect the engine
co olin g system against freezing downto
approximate ly-35 ‡ (-37 †).
Rnot exceed 55% (antifreeze protection down
to -49 ‡ [-45 †]). Otherwise, heat willnotbe
dissipat ed as effectively.
Mercedes-Benz recommends an antifreeze/
corrosion inh ibitor concentrate inaccordance
wit h MB Specifications for Service Products
310.1.
iWhen the veh icle isfirstdeliv ered, it is fille d
wit h a coolant mixture that ensures adequate
antifreeze and anti-corrosion protection.
iThe coolant ischecked with every mainte-
nance interval at a qualified specialist work-
shop.

Windshield washer system
Important safety notes
GWARNING
Windshield washer concentrate could ignite if
it comes into contact with hot engine compo-
nents or the exhaust system. There isa risk of
fire and injury.
Make sure that no windshield washer con-
centrate is spilled next to the filler neck.
!Only MB SummerFit and MB WinterF it
washer fluid should bemixed together. The
spray nozzles may otherwise become
blocked.
Do not use distilled or de-ionized water. Other-
wise, the level sensor may givea false reading.
When handling washer fluid, observe the impor-
tant safety notes on service products
(
Ypage 378).
At temperatures above freezing:
XFill the washer fluid reservoir with a mixture of
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 mixture of
water 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 all

Climate control system refrigerant
Important safety notes
The clim ate control system of your vehicle is fil-
led with refrigerant R‑ 134a.
The instruction label regarding the refrigerant
type used can be found on the radiator cross
member.
!Only the refrigerant R‑134a and the PAG oil
approved by Mercedes-Benz may be used.
The appr oved PAG oil may not be mixed with
any other PAG oil that is not approved for
