road users:
Rwho have no lights, e.g. pedestrians
Rwho have poor lighting, e.g. cyclists
Rwhos elighting is blocked ,e.g. by abarrier
On very rare occasions, Adaptive Highbeam
Assist may fail to recognize other road users
that have lights, or may recognize them too

tivated or wil lbeactivated regardless. There is
ar isk of an accident.

to the prevailing light, visibility and traffic con-
ditions.
In particular, the detection of obstacles can be
restricted if there is:
Rpoor visibility, e.g. due to fog, heavy rain or

The antifreeze/corrosion inhibitor concentra-
tion in the engine cooling system should:
Rbe at least 50%. This will protectthe engine
cooling system against freezin gdown to
approximately -35 ‡(-37 †).
Rnot exceed 55% (antifreez eprotection 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 ServiceP roducts
310.1.
iWhen the vehicle is first delivered, it is filled
with acoolant mixture that ensures adequate
antifreeze and anti-corrosion protection.
iThe coolant is checked with every mainte-
nancei nterval at aqualified specialist work-
shop.

GWARNING
Windshield washer concentrate could ignite if it comes into contact with hot engine compo-
nentsort he exhaust system. There is arisk of
fire and injury.
Make sure that no windshield washer con-
centrate is spilled next to the filler neck.

blocked.
Do not use distilled or de-ionised water. Other-
wise, the level sensor may give afalse reading.
When handling washer fluid, observe the impor-
tant safety notes on service products
(
Ypage 284).
At temperatures above freezing:
XFill the washer fluid reservoir with amixture of
water and windshield washer fluid, e.g. MB
SummerFit.
XAdd 1part MB SummerFit to 100 parts water.
At temperatures below freezing:
XFill the washer fluid reservoir with amixture of
water and washer fluid, e.g. MB WinterFit.
For the correctm ixing ratio refer to the infor-
mation on the antifreeze reservoir.
