If ice has formed on the road, tire traction will

You should pay special attention to road
conditions when temperatures are around
the freezing point.
All passenger car tires must conform to the
statutory safety requirements in addition to
these grades.
Mercedes-Benz recommends a minimum tire
tread depth of 1/6 in (4 mm) for all four winter
tires (Y page 154) to maintain normal driving
characteristics in winter. Winter tires can
reduce the braking distance on snow covered
surfaces in comparison to summer tires. The
braking distance is still much further than on
surfaces that are not icy or covered with
snow. Take appropriate care when driving.
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified
U.S. government test track. For example, a
tire graded 150 would wear one and one-half
times as well on the government test track as
a tire graded 100.
! Avoid wheelspin. This can lead to damage
to the drive train.
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 conditions.
Temperature
G Warning
The temperature grade for this tire is
established for a tire that is properly inflated
and not overloaded. Excessive speed,
underinflation, or excessive loading, either
separately or in combination, can cause
excessive heat build-up and possible tire
failure.
Traction
G Warning
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics.
The temperature grades are A (the highest),
B, and C. These represent the tire's
resistance 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
temperature can cause the material of the tire
to degenerate and reduce tire life.
Furthermore, excessive temperature can lead
to sudden tire failure. Grade C corresponds
to a level of performance that all passenger
The traction grades, from highest to lowest,
are AA, A, B, and C. These grades represent
the tire's ability to stop on a wet surface as
measured under controlled conditions on
specified government test surfaces of asphalt
and concrete. A tire marked C may have poor
traction performance.

Automotive readers have rated 2011 Mercedes-Benz C250 C300 C350 4MATIC C63 AMG W204 Owners Manual 4.8 out of 5.0 based on 6 product reviews. Excellent site, useful for persons needing more understanding of c-class models
Very good, if I will downaload it, thanks! But why your website first ask write good review, and then you let download?
Engine temperature need to check with owner manual
it's a very useful documents, when u lost your user manual!it's a very useful documents, when u lost your user manual!
userful documents, when you get lost your manual
