Mercedes-Benz GLC Coupe 2016, Owner'S Manual

Page: 370 / 377

The antifreeze concentrate/anti-corrosion addi-
tive concentration in the engine cooling system
should:
R
be at least 50%. This will protect the engine
cooling system against freezing down to
approximately -37 †.
R
not exceed 55% (antifreeze protection down
to -45 †). Heat will otherwise not be dissipa-
ted as effectively.
Mercedes-Benz recommends an antifreeze/
anti-corrosion additive concentration in accord-
ance with MB Specifications for Service Prod-
ucts 310.1.
i
When the vehicle is first delivered, it is filled
with a coolant mixture that ensures adequate
antifreeze and corrosion protection.
i
The coolant is checked at every mainte-
nance interval at a qualified specialist work-
shop.
Windscreen washer system
Important safety notes
G
WARNING
If windscreen washer concentrate comes into
contact with hot components of the engine or
the exhaust system, it can ignite. There is a
risk of fire and injury.
Make sure the windscreen washer concen-
trate does not come into contact with 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 the washer fluids SummerFit and Win-
terFit can be mixed. Otherwise, the spraying
nozzles could become blocked.
Do not use distilled or de-ionised water, other-
wise the level sensor may give a false reading.
When handling washer fluid, observe the impor-
tant safety notes on service products
(
Y
page 360).
At temperatures above freezing:
X
Fill the washer fluid reservoir with a mixture of
water and washer fluid, e.g. MB SummerFit.
Mix 1 part MB SummerFit to 100 parts water.
At temperatures below freezing:
X
Fill the washer fluid reservoir with a mixture of
water and washer fluid, e.g. MB WinterFit.
