Fuel Important safety notes G WARNING Gasoline is highly flammable and poisonous. It burns violently and can cause serious personal injury. Never allow sparks, flames or smoking materials near gasoline. Turn off the engine before refueling.

Whenever you are around gasoline, avoid inhaling fumes and any skin or clothing contact. Direct skin contact with fuels and the inhalation of fuel vapors are damaging to your health.

Premium-grade unleaded gasoline ! To ensure the longevity and full

performance of the engine, only premium- grade unleaded gasoline may be used.

21 Mixed with water or premixed washer fluid with antifreeze protection.

274 Service products and capacities

If there is no premium-grade unleaded gasoline available and regular-grade unleaded gasoline may be used; please observe the following precautions: Ronly fill the fuel tank to half full with

regular-grade unleaded gasoline and fill the rest with premium-grade unleaded gasoline as soon as possible.

Rdo not drive at the maximum speed. Ravoid sudden acceleration. Rif the vehicle is carrying a light load, e.g. two passengers without luggage, do not allow the engine to rev above 3,000 rpm.

Rif the vehicle is fully loaded or is being

operated in mountainous terrain, do not depress the accelerator pedal further than Ô of the pedal travel.

Fuel requirements Use only premium-grade unleaded gasoline. The octane number should be at least 91. Details can be found on the gas pump. The octane number is the average value of the Research Octane Number (RON) and the Motor Octane Number (MON): (RON + MON) / 2, also known as knock resistance. Reformulated Gasoline (RFG) and/or unleaded gasoline with additives can be used if the concentration of the additives in the fuel does not exceed 10%, e.g.: REthanol RTAME RETBE RIPA RTBA For MTBE, the concentration should not exceed 15%. The concentration of methanol in gasoline including other additives must not exceed 3%. Using mixtures of methanol and ethanol is not permitted. Gasohol, a mixture of 10% ethanol and 90% unleaded gasoline, can be used.

All of these mix fuels must fulfill the fuel requirements, e.g.: Rknock resistance Rboiling point Rvapor pressure

Additives in gasoline One of the major problems in engine design is the creation of carbon deposits during the process of burning fuel. Mercedes-Benz recommends that you use fuel brands containing additives that prevent the build-up of carbon deposits. If you use fuels without these additives for an extended period of time, there may be a build up of carbon deposits, especially on the inlet valves and in the combustion chamber. This could lead to engine problems, e.g.: Rlonger engine warm-up phase Runeven idle Rengine noise Rmisfiring Rloss of power In areas where carbon deposits can build up, because of the lack of availability of gasoline with the corresponding additives, Mercedes- Benz recommends the use of additives that have been approved for Mercedes-Benz vehicles. Consult an authorized Mercedes-Benz Center or go to the Internet site http://bevo.mercedes-benz.com for a list of approved products. Comply with the instructions for use on the product label. Do not mix other fuel additives with fuel. This causes unnecessary costs and could damage the engine. ! Do not refuel with low-grade fuel and do not use fuel additives that are not tested and approved for Mercedes-Benz vehicles. Damage to or malfunctions of the fuel system may otherwise occur.

Engine oil Please bear the following in mind The engine oils are matched to the performance of Mercedes-Benz engines and service intervals. For this reason, only use engine oils and oil filters that are approved for vehicles with a service system. For a list of approved engine oils and oil filters, consult an authorized Mercedes-Benz Center or go to the Internet site http://bevo.mercedes-benz.com (USA only). ! Never use engine oil or an oil filter of a specification other than is necessary to fulfill the prescribed service intervals. Do not change the engine oil or oil filter in order to achieve longer replacement intervals than those prescribed. You could otherwise cause engine damage or damage to the exhaust gas aftertreatment. Follow the instructions in the service interval display regarding the oil change. Otherwise, you may damage the engine and the exhaust gas aftertreatment.

This could damage the engine.

Engine oil viscosity Viscosity describes the flow characteristics of a fluid. If an engine oil has a high viscosity,

Service products and capacities

275

this means that it is thick; a low viscosity means that it is thin. Select an engine oil with an SAE (viscosity) classification suitable for the prevailing outside temperatures. The following table shows the correct SAE classification to be used. The low-temperature characteristics of engine oils can deteriorate significantly, e.g. as a result of aging, soot and fuel deposits. It is therefore strongly recommended that you carry out regular oil changes using an approved engine oil with the appropriate SAE classification.

Refrigerant of the air-conditioning system The air-conditioning system is filled with R134a (HFC) refrigerant and a special PAG lubricant. ! Never use refrigerant R 12 (CFC) or

mineral lubricants. Otherwise, you could damage the air-conditioning system.

Brake fluid G WARNING The brake fluid constantly absorbs moisture from the air; this lowers its boiling point. If the boiling point of the brake fluid is too low, vapor pockets may form in the brake system when the brakes are applied hard (e.g. when driving downhill). This would impair braking efficiency.

276 Service products and capacities

You should have the brake fluid renewed at regular intervals. The brake fluid change intervals can be found in the Maintenance Booklet.

Only use brake fluid approved by Mercedes- Benz. Information about approved brake fluids can be obtained from any authorized Mercedes-Benz Center.

Coolant Important safety notes The coolant is a mixture of water and antifreeze/corrosion inhibitor. It performs the following tasks: Ranti-corrosion protection Rantifreeze protection Rraising the boiling point The engine cooling system is filled at the factory with coolant which contains an antifreeze/corrosion inhibitor that ensures protection down to approximately -35 ‡ (-37 † ). ! Only add coolant that has been premixed

with the desired antifreeze protection. Otherwise, the engine could be damaged. Further information on coolants and on filling can be found in the Mercedes-Benz Specifications for Service Products, MB Approval 310.1, e.g. on the Internet at http://bevo.mercedes-benz.com. You can also consult an authorized Mercedes-Benz Center.

! Always use a suitable coolant mixture,

even in countries where high temperatures prevail. Otherwise, the engine cooling system is not sufficiently protected from corrosion and the boiling point will be too low.

If the coolant has antifreeze protection down to -35 ‡ (-37 † ), the boiling point of the coolant in the pressurized system is approximately 266 ‡ (130 † ).

Your vehicle has a range of aluminum components. Aluminum components in the engine make it necessary to use anticorrosion/antifreeze coolant which has been specifically formulated to protect the aluminum parts. Using other antifreeze/ corrosion inhibitors without these characteristics affects the service life. The coolant must be used throughout the year in order to maintain the necessary corrosion protection and provide protection from overheating. In the Maintenance Booklet, you can find information on the intervals for renewal. The renewal interval is determined by the coolant type and the engine cooling system design. The renewal interval in the Maintenance Booklet is only valid if the coolant is renewed or replenished with Mercedes-Benz approved products. Therefore, only use MB 326.0 antifreeze/ corrosion inhibitor or another Mercedes-Benz approved product of the same specification. Information on other products with the same specifications that are approved by Mercedes-Benz can be obtained at an authorized Mercedes-Benz Center or on the Internet at http://bevo.mercedes-benz.com. The coolant is checked at every maintenance interval at an authorized Mercedes-Benz Center. The antifreeze/corrosion inhibitor concentration in the engine cooling system should: Rbe at least 50%. This will protect the engine

cooling system against freezing down to approximately -35 ‡ (-37 † ).

Rnot exceed 55% (antifreeze protection to -49 ‡ [-45 † ]); otherwise, heat will not dissipate as effectively.

If the coolant level is too low, MB 325.0
antifreeze/corrosion inhibitor should be added. Have the engine cooling system checked for possible leaks.
