Coolants
The engine coolant is a mixture of water and anticorrosion/antifreeze, which provides:
• 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 approx. -22°F
(-30°C) and corrosion protection. 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
every 3 years. To provide the important corrosion protection, the solution must be at least 45%
anticorrosion/antifreeze (equals a 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 solution. Therefore, do not
use more than this amount of anticorrosion/antifreeze. If the coolant level is low, water and MB
anticorrosion/antifreeze should be used to bring it up to the proper level (have cooling system
checked for signs of leakage). 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,
consult your authorized Mercedes-Benz dealer.
Anticorrosion/antifreeze
Your vehicle contains a number of aluminum parts. The use of aluminum components in motor
vehicle engines necessitates that anticorrosion/antifreeze coolant used in such engines be specifically
formulated to protect the aluminum parts. (Failure to use such anticorrosion/antifreeze coolant will
result in a significantly shortened service life.)
Therefore the following product is strongly recommended for use in your car: Mercedes-Benz
Anticorrosion/Antifreeze Agent. Before the start of the winter season (or once a year in the 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 dealer for
service.

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
Refer to the tire sidewall for the specific tire grades for t he tires with which this vehicle is equipped. All passenger car
tires must conform to federal safety requirements in addition to these grades.
Treadwear
The treadwear grade is a comparative rating based on t he 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 (11/2)
times as well on the government course as a tire grad ed 100. The relative performance of tires depends upon the
actual conditions of their use, however, and may depart signi ficantly 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 grade represent the tire's ability to stop on
wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and
concrete. A tire marked "C" ma y have poor traction performance.
Warning !
The traction grade assigned to this tire is based on straight-ahead braking traction tests and does not
include cornering, hydroplaning or peak traction characteristics.
Temperature
The temperature grades are A (the highest), B, and C, representing 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, and excessive
temperature can lead to sudden tire failure. The grade C co rresponds 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 performance on the laboratory test wheel than the minimum required by law.
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.
