345 Technical data
Fuels, coolants, lubricants, etc.
Damage or malfunctions resulting from
poor fuel quality or from blending specific
fuel additives are not covered by the
Mercedes-Benz Limited Warranty.Coolants
The engine coolant is a mixture of water
and anticorrosion / antifreeze, which pro-
vides:

corrosion protection


freeze protection


boiling protection (by increasing the
boiling point)
The cooling system was filled at the factory
with a coolant providing freeze protection
to approximately -22°F (-30°C) and corro-
sion protection.
If the antifreeze mixture is effective to
-22°F (-30°C), the boiling point of the cool-
ant in the pressurized cooling system is
reached at approximately 266°F (130°C).The coolant solution must be used year
round to provide the necessary corrosion
protection and increase in the boil-over
protection. You should have it replaced ev-
ery 15 years or 150 000 miles (250 000
km), whichever comes first.
Coolant system design and coolant used
stipulate the replacement interval. The
above replacement interval is only applica-
ble if MB 325.0 anticorrosion/antifreeze
solution or other Mercedes-Benz approved
products of equal specification (see Facto-
ry Approved Service Products pamphlet)
are used to renew the coolant concentra-
tion or bring it back up to the proper level.
To provide important corrosion protection,
the solution must be at least 45% anticor-
rosion/antifreeze (equivalent to freeze
protection to approx. - 22°F [-30°C]). If
you use a solution that is more than 55%
anticorrosion/antifreeze (freeze protec-
tion to approx. - 49°F [-45°C]), the engine
temperature will increase due to the lower heat transfer capability of the solution.
Therefore, do not use more than this
amount of anticorrosion/antifreeze.
If the coolant level is low, water and
MB 325.0 Anticorrosion /Antifreeze
should be used to bring it up to the proper
level (have cooling system checked for
signs of leakage). Please make sure that
the mixture is in accordance with label in-
structions.
The water in the cooling system must meet
minimum requirements, which are usually
satisfied by normal drinking water. If you
are not sure about the water quality, con-
sult your authorized Mercedes-Benz
Center.

346 Technical dataFuels, coolants, lubricants, etc.Anticorrosion/antifreeze
Your vehicle contains a number of alumi-
num parts. The use of aluminum compo-
nents in motor vehicle engines
necessitates that anticorrosion/antifreeze
coolant used in such engines be specifical-
ly formulated to protect the aluminum parts. (Failure to use such anticorro-
sion/antifreeze coolant will result in a sig-
nificantly shortened service life.)
Therefore, the following product is strongly
recommended for use in your vehicle:
Mercedes-Benz 325.0 Anticorrosion/Anti-
freeze Agent.Before the start of the winter season (or
once a year in hot southern regions), you
should have the anticorrosion/antifreeze
concentration checked. The coolant is also
regularly checked each time you bring your
vehicle to your authorized Mercedes-Benz
Center for service.

348 Technical dataConsumer information
Consumer informationThis has been prepared as required of all
manufacturers of passenger cars under Ti-
tle 49, Code of U.S. Federal Regulations,
Part 575 pursuant to the “National Traffic
and Motor Vehicle Safety Act of 1966”.Uniform tire quality grading
Quality grades can be found, where appli-
cable, on the tire sidewall between tread
shoulder and maximum section width. For
example:
All passenger car tires must conform to
federal safety requirements in addition to
these grades.Treadwear
The treadwear grade is a comparative rat-
ing based on the wear rate of the tire when
tested under controlled conditions on a
specified government test course. For ex-
ample, a tire graded 150 would wear one
and one-hal f ( 1½ ) ti m es as wel l on the g ov-
ernment course as a tire graded 100. The
relative performance of tires depends
upon the actual conditions of their use,
however, and may depart significantly
from the norm due to variations in driving
habits, service practices and differences in
road characteristics and climate.Traction
The traction grades, from highest to lowest
are AA, A, B, and C. Those grades repre-
sent the tire’s ability to stop on wet pave-
ment as measured under controlled
conditions on specified government test
surfaces of asphalt and concrete. A tire
marked C may have poor traction perfor-
mance.Tread wear

The traction grade assigned to this tire is
based on straightahead braking traction
tests, and does not include acceleration,

characteristics.
