Engine oils


Engine oils are specifically tested for their suitability in our engines. Therefore, only use engine oils approved by Mercedes-Benz. Information on approved engine oils is available in the Factory Approved Service Products pamphlet, or at your authorized Mercedes-Benz Center.


Always check the oil filler cap (컄 page 255) for important information pertaining to the engine oil needing to meet a specific Mercedes-Benz specifi- cation (e.g. MB 229.5). If such informa- tion is printed on the oil filler cap, only use an engine oil from the list of ap- proved engine oils in the Factory Ap- proved Service Products pamphlet that meets the specification indicated on the oil filler cap.


352


Using engine oils of other specification may cause the FSS to incorrectly deter- mine the next service interval and will result in engine damage not covered by the Mercedes-Benz Limited Warranty.


Please follow FSS recommendations for scheduled oil changes. Failure to do so could result in engine damage not covered by the Mercedes-Benz Limited Warranty.


Engine oil additives


Do not blend oil additives with engine oil. They may damage the engine. Damage or malfunctions resulting from blending oil additives are not covered by the Mercedes-Benz Limited Warranty.


Air conditioning refrigerant


R-134a (HFC) refrigerant and special PAG lubricating oil is used in the air conditioning system.


Never use R-12 (CFC) or mineral-based lubricating oil. Otherwise damage to the system will occur.


Brake fluid


During vehicle operation, the boiling point of the brake fluid is continuously reduced through the absorption of moisture from the atmosphere. Under extremely strenu- ous operating conditions, this moisture content can lead to the formation of bubbles in the system, thus reducing the system’s efficiency. Therefore, the brake fluid must be replaced every two years, preferably in the spring. Only brake fluid approved by Mercedes-Benz is recommended. Your authorized Mercedes-Benz Center will provide you with additional information.


Premium unleaded gasoline


Fuel requirements


To maintain the engine’s durability and performance, premium unleaded gaso- line must be used. If premium unleaded is not available and low octane fuel is used, follow these precautions: 앫 Have the fuel tank only partially


filled with unleaded regular and fill up with premium unleaded as soon as possible.


앫 Avoid full throttle driving and abrupt


acceleration.


앫 Do not exceed an engine speed of 3000 rpm if the vehicle is loaded with a light load such as two persons and no luggage.


앫 Do not exceed 2/3 of maximum accelerator pedal position if the vehicle is fully loaded or operating in mountainous terrain.


Flexible Fuel Vehicles (identified by a label reading Premium gasoline or E85 only! are designed to operate on premium unleaded gasoline or Ethanol fuel (E85) or any mixture of these two. See notes on Flexible Fuel Vehicles (컄 page 354).


Only use premium unleaded meeting ASTM standard D 439: 앫 The octane number (posted at the


pump) must be 91 min. It is an average of both the Research (R) octane num- ber and the Motor (M) octane number: (R+M)/2. This is also known as the ANTI-KNOCK INDEX.


Technical data Fuels, coolants, lubricants, etc.


Unleaded gasoline containing oxygenates such as Ethanol, IPA, IBA and TBA can be used provided the ratio of any one of these oxygenates to gasoline does not exceed 10%; MTBE must not exceed 15%. The ratio of Methanol to gasoline must not exceed 3% plus additional cosolvents. Using mixtures of Ethanol and Methanol is not allowed. Gasohol, which contains 10% Ethanol and 90% unleaded gasoline, can be used. These blends must also meet all other fuel requirements, such as resistance to spark knock, boiling range, vapor pressure, etc.


353


Damage or malfunctions resulting from poor fuel quality or from blending specific fuel additives are not covered by the Mercedes-Benz Limited Warranty.


Flexible Fuel Vehicles


Flexible Fuel Vehicles are identified by a label reading Premium gasoline or E85 only! on fuel filler flap. These vehicles are designed to operate on premium unleaded gasoline or Ethanol fuel (E85), or on any mixture of these two. Ethanol fuel (E85) is a mixture of approximately 85% Ethanol and 15% unleaded gasoline.


Warning!


Ethanol fuel (E85) and its fumes are highly flammable, poisonous and burn easily. Etha- nol fuel can cause serious injuries if ignited or if you come into contact with it or inhale fumes of it. Avoid inhalation of Ethanol fumes and skin contact with Ethanol. Extin- guish all open flames before fueling. Never smoke or create sparks close to Ethanol.


Switching fuels For best performance and driveability it is recommended to use either one or the other fuel. A refueling pattern that alternates between the two different fuels should be avoided if possible.


Technical data Fuels, coolants, lubricants, etc.


Gasoline additives


A major concern among engine manufacturers is carbon build-up caused by gasoline. Mercedes-Benz recommends only the use of quality gasoline containing additives that prevent the build up of carbon deposits. After an extended period of using fuels without such additives, carbon deposits can build up especially on the intake valves and in the combustion area, leading to engine performance problems such as: 앫 Warm-up hesitation 앫 Unstable idle 앫 Knocking/pinging 앫 Misfire 앫 Power loss Do not blend any specific fuel additives with fuel. This only results in unnecessary cost and may be harmful to engine operation.


354


When switching fuels, make sure: 앫 Fuel level is below half full. 앫 Fuel level is above reserve (fuel reserve


warning lamp is not lit).


앫 Amount of added fuel is more than


5 gallons (20 liters).


앫 Ignition is off during refill. 앫 Immediately after refueling engine is started and operated for at least five minutes.


These precautions and recommendations are supposed to prevent any difficulties when starting and operating the engine which otherwise may be experienced before the engine has fully adapted to the different fuel. If in spite of these recommendations the engine does not perform properly, adding more gasoline [at least 3 gallons (12 liters)] to the fuel may improve the engine behavior.


Cold weather performance It is possible that starting times will signif- icantly increase at temperatures below 32°F (0°C). At low temperatures the use of a block heater (Canada only) is recommended (see your authorized Mercedes-Benz Center for further information). Rough idling may also be experienced at such temperatures before the engine is fully warmed up.


E85 fuel is unsuitable for use when ambient temperatures fall below 14°F (-10°C).


Hot weather performance At ambient temperatures above 95°F (35°C) start times may increase and be accompanied by a rough idle following the start.


Technical data Fuels, coolants, lubricants, etc.


Cruising range E85 fuel contains less energy per gallon than gasoline. To ensure that engine per- formance with Ethanol fuel is similar to that when using gasoline, the engine must burn more Ethanol fuel. As a result, it is to be expected that the fuel consumption will increase when using E85 compared to gasoline operation.


Use of E85 may reduce your driving range.


Maintenance Please inform your Mercedes-Benz Center if you use or have used E85 fuel when your vehicle is delivered for maintenance or repairs.


355


Technical data Fuels, coolants, lubricants, etc.


Coolants


The engine coolant is a mixture of water and anticorrosion/antifreeze, which provides: 앫 Corrosion protection 앫 Freeze protection 앫 Boiling protection (by increasing the


boiling point)


The cooling system was filled at the factory with a coolant providing freeze protection to approximately -22°F (-30°C) and corrosion protection. If the antifreeze mixture is effective to -22°F (-30°C), the boiling point of the coolant in the pressurized cooling system is reached at approx. 266°F (130°C).


356


The coolant solution must be used year-round to provide the necessary corro- sion protection and increase boil-over protection. Refer to Service Booklet for replacement interval. Coolant system design and coolant used stipulate the replacement interval. The replacement interval published in the Service 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 renew 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 solution. 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 instructions. 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 Center.


Technical data Fuels, coolants, lubricants, etc.


Failure to use such anticorrosion/anti- freeze coolant will result in a significantly shortened service life. Therefore, the following product is strongly recommended for use in your vehicle: Mercedes-Benz 325.0 Anticorrosion/Antifreeze 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 your authorized Mercedes-Benz Center for service.


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 specifi- cally formulated to protect the aluminum parts.

왔 Consumer information The following text is published 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 applicable, on the tire sidewall between tread shoulder and maximum section width. For example:


Tread wear 200


Traction AA


Temperature


All passenger car tires must conform to federal safety requirements in addition to these grades.


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 government test course. For example, a tire graded 150 would wear one and one-half (11/2) times as well on the government 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 varia- tions in driving habits, service practices and differences in road characteristics and climate.


Technical data Consumer information


Traction The traction grades, from highest to lowest are AA, A, B, and C. Those grades 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 may have poor traction performance.


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.


359


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.


Technical data Consumer information


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. 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 performance on the laboratory test wheel than the minimum required by law.
