Technical data
The antifreeze/corrosion inhibitor concentra-
tion in the engine cooling system should: R
be at least 50%. This will protec tt he engine
cooling system against freezin gd own to
approximately -35 ‡( -37 †).R
not exceed 55% (antifreez ep rotection 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 inhibitor concentrate in accordance
with MB Specifications for Servic eP roducts
310.1.
i When the vehicle is first delivered, it is filled
with ac oolant mixture that ensures adequate
antifreeze and anti-corrosion protection.
i The coolant is checked with every mainte-
nanc ei nterval at aq ualified specialist work-
shop.

Important safety notes
G WARNING
Windshield washer concentrate could ignite if
it comes into contact with hot engine compo-
nent sort he exhaust system. There is ar isk of
fire and injury.
Make sure that no windshield washer con-
centrate is spilled next to the filler neck.
! Only use washer fluid that is suitable for
plastic lamp lenses, e.g. MB SummerFit or MB
WinterFit. Unsuitable washer fluid could dam-
age the plastic lenses of the headlamps. ! Only MB SummerFit and MB WinterFit
washer fluid should be mixed together. The
spray nozzles may otherwise become
blocked.
Do not use distilled or de-ionised water. Other-
wise, the level sensor may give af alse reading.
When handling washer fluid, observe the impor-
tant safety notes on service products
( Y
page 290).
At temperatures above freezing: X
Fill the washer fluid reservoir with am ixture of
water and windshield washer fluid, e.g. MB
SummerFit. X
Add 1p art MB SummerFit to 100 parts water.
At temperatures below freezing: X
Fill the washer fluid reservoir with am ixture of
water and washer fluid, e.g. MB WinterFit.
For the correc tm ixing ratio refer to the infor-
mation on the antifreeze reservoir.
i Add windshield washer fluid, e.g. MB Sum-
merFit or MB WinterFit, to the washer fluid all
year round.
Climate control system refrigerant
Important safety notes The climate 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 approved PAG oil may not be mixed with
any other PAG oil that is not approved for
R-134a refrigerant .O therwise, the climate
control system may be damaged.
Servic ew ork, such as refilling with refrigerant or
replacing component parts, may only be carried
out by aq ualified specialist workshop. All appli-
cable regulations, as well as SAE standard J639,
must be adhered to.
Always have work on the climate control system
carried out at aq ualified specialist workshop.294
