must be used in the system all year round to
ensure anti-corrosion protection and a raised
boiling point – even in countries with high
outside temperatures.
To prevent damage to the engine cooling sys- tem, use only approved corrosion inhibitor/
antifreeze that comply with the Mercedes-
Benz Specifications for Service Products.
We recommend corrosion inhibitor/anti-
freeze that meets the requirements in MB
Specifications for Service Products Sheet
Number 325.
Check the antifreeze/corrosion inhibitor con- centration in the coolant every six months.
The percentage of corrosion inhibitor/anti-
freeze additive in the engine cooling system
should:
R be at least 50%. This way, the engine cool-
ing system is protected against freezing
down to approximately -35 ‡ (-37 †).
R not exceed 55% (antifreeze protection
down to -49 ‡ [-45 †]). Otherwise, heat
will not be dissipated as effectively.
If there has been coolant loss, do not refill
only with water. If the vehicle has lost coolant,
add equal parts water and corrosion inhibi-
tor/antifreeze additive. The water used as
part of the coolant mixture must fulfill certain requirements; these are usually fulfilled by
drinking water. If the water quality is not suf-ficient, you must treat the water.

Important safety notes G
WARNING
Windshield washer concentrate could ignite if it comes into contact with hot engine compo-
nents or the exhaust system. There is a risk 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 damage the plastic lenses of the
headlamps. 326
