Mercedes-Benz 2011 R-Class Automobile User Manual


 
Antifreeze separately from each other,
could cause engine damage not covered by
the Mercedes-Benz Limited Warranty.
!
Always use a suitable coolant mixture,
even in countries where high temperatures
prevail.
Otherwise, the cooling system will not be
sufficiently protected from corrosion, and
the boiling point will be too low.
If the coolant has antifreeze protection down
to -35 ‡ (-37 †), the boiling point of the
coolant in the pressurized system is
approximately 266 ‡ (130 †).
The coolant must be used throughout the year
in order to maintain the necessary corrosion
protection and 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 cooling system design.
The renewal interval in the Service Booklet is
only valid if the coolant is added or renewed
with Mercedes-Benz approved products.
Therefore, only use MB 325.0 Anticorrosion/
Antifreeze or another Mercedes-Benz
approved product of the same specification.
Information on other Mercedes-Benz
approved products of the same specification
can be obtained at any authorized Mercedes-
Benz Center or on the Internet at
http://www.mbusa.com (USA only).
The anticorrosion/antifreeze concentration
in the cooling system should:
R
be at least 50%. This will protect the cooling
system against freezing down to around
-35 ‡ (-37 †).
R
not exceed 55% (antifreeze protection
down to -49 ‡ [-45 †]); otherwise, heat will
not be dissipated as effectively.
If the coolant level is too low, a mixture of
water and MB 325.0 Anticorrosion/
Antifreeze should be added. Have the cooling
system checked for leaks. Please make sure
the mixture is in accordance with label
instructions.
The water in the cooling system must meet
minimum requirements, which are usually
satisfied by normal drinking water.
If you are unsure about the water quality,
contact an authorized Mercedes-Benz
Center.
