corrosion inhibitors without these
characteristics affects the service life.
The coolant must be used throughout the year
in order to maintain the necessary corrosion
protection and to provide protection from
overheating. In the Service Booklet, you can
find information on the intervals for renewal.
The renewal interval is determined by the
coolant type and the engine cooling system
design. The renewal interval in the Service
Booklet is only valid if the coolant is renewed
or filled up with Mercedes-Benz approved
products. Therefore, only use MB 325.0 or
326.0 anticorrosion/antifreeze or another
Mercedes-Benz approved product of the
same specification.
Information on other products with the same
specifications that are approved by
Mercedes-Benz can be obtained at an
authorized Mercedes-Benz Center or on the
Internet at http://bevo.mercedes-benz.com.
The coolant is checked at every maintenance
interval at an authorized Mercedes-Benz
Center.
The antifreeze/corrosion inhibitor
concentration in the engine cooling system
should:
R be at least 50%. This will protect the engine
cooling system against freezing down to
approximately -35 ‡ (-37 † ).
R not exceed 55% (antifreeze protection to
-49 ‡ [-45 † ]); otherwise, heat will not
dissipate as effectively.
If the coolant level is too low, MB 325.0 or
326.0 anticorrosion/antifreeze should be
added. Have the engine cooling system
checked for possible leaks.

G WARNING
Washer solvent/antifreeze is highly
flammable. Do not spill washer solvent/
antifreeze on hot engine parts, because it may
ignite and burn. You could be seriously
burned.
Use MB SummerFit windshield washer
concentrate at temperatures above freezing:
X Mix 1 part MB SummerFit with 100 parts
water.
Use MB WinterFit windshield washer
concentrate at temperatures below freezing:
X At temperatures down to 14 ‡ (Ò 10 †):
mix 1 part MB WinterFit with 2 parts water.
X At temperatures down to Т 4 ‡ (Т 20 †):
mix 1 part MB WinterFit with 1 part water.
X
At temperatures down to Т 20.2 ‡
(Т 29 †): mix 2 parts MB WinterFit with 1
part water.
! Only SummerFit and WinterFit can be
mixed. Otherwise, the jets could become
blocked.
