2004 MERCEDES-BENZ CL55AMG technical data

377 Technical data
Fuels, coolants, lubricants, etc.
Coolant system design and coolant used
stipulate the replacement interval. The re-
placement interval published in the Ser-
vice Booklet is only applicable if MB 325.0
anticorrosion / antifreeze solution or other
Mercedes-Benz approved products of
equal specification (see Factory Approved
Service Products pamphlet) are used to re-
new the coolant concentration or bring it
back up to the proper level.
To provide important corrosion protection,
the solution must be at least 45%
anticorrosion / antifreeze [equivalent to
freeze protection to approx. –22°F
(–30°C)]. If you use a solution that is more
than 55% anticorrosion / antifreeze [freeze
protection to approx. –49°F (–45°C)], the
engine temperature will increase due to
the lower heat transfer capability of the so-
lution. 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 the
mixture is in accordance with label instruc-
tions.
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 an authorized Mercedes-Benz Center.Anticorrosion / antifreeze
Your vehicle contains a number of alumi-
num parts. The use of aluminum compo-
nents in motor vehicle engines
necessitates that anticorrosion / anti-
freeze coolant used in such engines be
specifically formulated to protect the alu-
minum
parts. (Failure to use such anticorrosion /
antifreeze coolant will result in a signifi-
cantly shortened service life.)
Therefore, the following product is strongly
recommended for use in your vehicle:
Mercedes-Benz 325.0 Anticorrosion / An-
tifreeze 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 an authorized Mercedes-Benz
Center for service.

Windshield and headlamp washer system
Both the windshield and headlamp washer
systems are supplied from the windshield
washer fluid reservoir.
The windshield and headlamp washer fluid
reservoir has a capacity of approx.
7.1 US qt. (6.7 l).

Refill the reservoir with MB Windshield
Washer Concentrate and water (or con-
centrate and commercially available
premixed windshield washer solvent /
antifreeze, depending on ambient tem-
peratures).Windshield and headlamp washer fluid
mixing ratio
For temperatures above freezing point, use
MB Windshield Washer Concentrate “S”
and water:


1 part “S” to 100 parts water
[40 ml “S” to 1 gallon (4 liters) water].
For temperatures below freezing point, use
MB Windshield Washer Concentrate “S”
and commercially available premixed
windshield washer solvent / antifreeze:


1 part “S” to 100 parts solvent
[40 ml “S” to 1 gallon (4 liters) solvent].
Warning
G
Washer solvent /antifreeze is highly flamma-
ble. Do not spill washer solvent /antifreeze
on hot engine parts, because it may ignite
and burn. You could be seriously burned.

380 Technical dataConsumer information
Consumer informationThe following text is published as required
of all manufacturers of passenger cars un-
der Title 49, Code of U.S. Federal Regula-
tions, 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.Tread wear
The tread wear 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-half (1½) times as well on the gov-
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

Warning
G
The traction grade assigned to this tire is
based on straightedge braking traction
tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics.

381 Technical data
Consumer information
Temperature
The temperature grades are A (the high-
est), B, and C, representing the tire’s resis-
tance to the generation of heat and its
ability to dissipate heat when tested under
controlled conditions on a specified indoor
laboratory test wheel. Sustained high tem-
perature can cause the material of the tire
to degenerate and reduce tire life, and ex-
cessive temperature can lead to sudden
tire failure. Grade C corresponds to a level
of performance which all passenger car
tires must meet under the Federal Motor
Vehicle Safety Standard No. 109. Grades B
and A represent higher levels of perfor-
mance on the laboratory test wheel than
the minimum required by law.
Warning
G
The temperature grade for this tire is estab-
lished for a tire that is properly inflated and
not overloaded. Excessive speed, underin-
flation, or excessive loading, either sepa-
rately or in combination, can cause
excessive heat build-up and possible tire
failure.
