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).

왘

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:

앫

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:

앫

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.

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.

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.
