Technical data

Fuels, coolants, lubricants etc.

Windshield washer system and 
headlamp cleaning system*

Both the windshield washer and headlamp 
cleaning system* are supplied from the 
windshield washer fluid reservoir.

The windshield and headlamp washer fluid 
reservoir has a capacity of approx. 
8.0 US qt (7.6 l).

Refill the reservoir with MB Windshield 
Washer Concentrate “S” and water (or 
concentrate and commercially avail-
able premixed windshield washer 
solvent/antifreeze, depending on am-
bient temperatures).

Windshield and headlamp washer fluid 
mixing ratio

For temperatures above freezing, 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, 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 flam-
mable. Do not spill washer 
solvent/antifreeze on hot engine parts, be-
cause it may ignite and burn. You could be 
seriously burned.

Technical data

Consumer information

Consumer information

This has been prepared as required of all 
manufacturers of passenger cars under 
Title 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.

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.

Warning!

G

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

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. The grade C corresponds to a 
level of performance which all passenger 
car tires must meet under the Federal Mo-
tor Vehicle Safety Standard No. 109. 
Grades B and A represent higher levels of 
performance 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.
