Fuel

Important safety notes

WARNING
Gasoline and diesel fuels are highly flammable and poisonous. They burn violently and can cause serious injury.

Never allow sparks, flames or smoking materials near gasoline or diesel fuel!

Turn off the engine before refueling.

Whenever you are around gasoline or diesel fuel, avoid inhaling fumes and any skin or clothing contact. Extinguish all smoking materials.

Direct skin contact with fuels and the inhalation of fuel vapors are damaging your health.

Premium-grade unleaded gasoline

To ensure the longevity and full performance of the engine, only premiumgrade unleaded gasoline may be used.

If there is no premium-grade unleaded gasoline available and regular-grade unleaded gasoline may be used; please observe the following precautions:

 - only 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.

 - do not drive at the maximum speed.

 - avoid sudden acceleration.

 - if the vehicle is carrying a light load, e.g.

two passengers without luggage, do not allow the engine to rev above 3,000 rpm.

 - if the vehicle is fully loaded or is being operated in mountainous terrain, do not depress the accelerator pedal further than 2/3 of the pedal travel.

Fuel requirements

Gasoline engines

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.:

 - Ethanol
 - TAME
 - ETBE
 - IPA
 - TBA

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.:

 - knock resistance
 - boiling point
 - vapor pressure

Diesel engines – important safety notes

Only use commercially available ULTRALOW SULFUR DIESEL FUEL (ULSD, 15 ppm MAXIMUM SULFUR) that meets the ASTM D975 standard. Failure to use ULTRA-LOW SULFUR DIESEL FUEL (ULSD) can severely damage the vehicle's exhaust gas aftertreatment system.

Do not fill the tank with gasoline. Do not blend diesel fuel with gasoline or kerosene.

Otherwise, the fuel system and the engine could be damaged.

To prevent malfunctions, diesel fuel with improved flow characteristics is available in the winter months. Check with your gas station.

Information on the fuel grade can usually be found on the gas pump. If the information cannot be found on the gas pump, ask the gas station personnel. For further information, consult an authorized Mercedes-Benz Center or go to the Internet site http://www.mbusa.com (USA only).

Diesel engines – fuels containing biodiesel (FAME [fatty acid methyl ester]) Mercedes-Benz USA approves the use of B5 (ULSD with a maximum of up to five percent by volume biodiesel) for all diesel engines with common rail direct injection (CDI) and BlueTEC.

Pure biodiesel and diesel fuels that have a higher percentage of biodiesel, e.g. B20, can damage the fuel system and the engine and are therefore not approved.

For further information, please ask the gas station personnel. The label on the gas pump must indicate clearly that the B5 biodiesel blend fulfills the ULSD standard. If the label is not clear, do not refuel the vehicle.

Do not refuel your vehicle with fuels unless they have been approved by Mercedes-Benz.

Additives in gasoline

One of the main problems of poor fuel quality is the forming of deposits that are caused during the gasoline combustion process.

Mercedes-Benz recommends that you use fuel brands that have the additives.

If you use fuels without these additives for an extended period of time, there may be a buildup of carbon deposits, especially on the inlet valves and in the combustion chamber.

This could lead to engine problems, e.g.:

 - longer engine warm-up phase
 - uneven idle
 - engine noise
 - misfiring
 - loss of power

Carbon deposits may form if the availability of gasoline with relevant additives is insufficient (in certain regions). In this case, 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://www.mbusa.com (USA only) for a list of approved products. Observe 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.

DEF

Important safety notes

For BlueTEC vehicles only.

DEF is a non-flammable, non-toxic, colorless, odorless and water-soluble fluid.

Rinse surfaces that have come into contact with DEF immediately with water or remove DEF using a damp cloth and cold water. If the DEF has already crystallized, use a sponge and cold water to clean it. DEF residues crystallize after time and contaminate the affected surfaces.

High outside temperatures

If DEF heats up to over 122 °F (50 °C) for extended periods, e.g. as a result of direct sunlight on the DEF reservoir, DEF can decompose. Ammonia vapors develop as a result.

WARNING
When opening the filler cap of the DEF tank ammonia gas vapors may escape. Refill DEF in a well ventilated area only. Ammonia gas vapors have a pungent odor and are particularly irritating for your skin, mucous membranes, and eyes. Inhaling ammonia gas vapors will cause burning eyes, nose, and throat, as well as coughing and watering eyes.

Low outside temperatures

DEF freezes at a temperature of approximately 12 °F (–11 °C). The vehicle is equipped with a DEF preheating system when it leaves the factory. Winter operation is therefore also guaranteed at temperatures below 12 °F (–11 °C).

Additives

Only use DEF in accordance with ISO 22241. Do not use additives with DEF and do not dilute DEF with water. This may destroy the BlueTEC exhaust gas aftertreatment system.

Purity

Assuring the purity of DEF is particularly important with respect to avoiding malfunctions in the exhaust gas aftertreatment system.

If DEF is pumped out of the DEF tank, e.g.

during repair work, it must not be returned to the tank. The purity of the fluid can no longer be guaranteed.

Impurities in DEF (e.g. due to other service products, cleaning agents or dust) lead to:

 - increased emission values
 - damage to the catalytic converter
 - engine damage
 - malfunctions in the BlueTEC exhaust gas aftertreatment system

Engine oil

Please bear the following in mind

The engine oils are matched to the performance of Mercedes-Benz engines and service intervals. You should therefore only use engine oils and oil filters that are approved for vehicles with maintenance systems.

For a list of approved engine oils and oil filters, consult an authorized Mercedes-Benz Center or go to the Internet site http://www.mbusa.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.

The table shows which engine oils have been approved for your vehicle.

MB approval is indicated on the oil

MB approval is indicated on the oil containers.

Additives

Do not use any additives in the engine oil.

This could damage the engine.

Engine oil viscosity

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

Refrigerant of the air-conditioning system

The air-conditioning system is filled with R134a 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

WARNING
Over a period of time, the brake fluid 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.

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

Only use brake fluid approved by Mercedes- Benz. Information about approved brake fluids can be obtained from any authorized Mercedes-Benz Center or on the Internet at http://bevo.mercedes-benz.com.

Coolant

Important safety notes

The coolant is a mixture of water and antifreeze/corrosion inhibitor. It performs the following tasks:

 - corrosion protection
 - antifreeze protection
 - raising the boiling point

The engine cooling system is filled at the factory with coolant that contains an antifreeze/corrosion inhibitor that ensures protection down to approximately -35 °F (-37 °C).

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 overheating.

If the coolant has antifreeze protection down to -35 °F (-37 °C), the boiling point of the coolant under operating conditions is approximately 266 °F (130 °C).

Your vehicle has a range of aluminum components. Aluminum components in the engine make it necessary to use antifreeze/ corrosion inhibitor coolant that 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 to provide protection from overheating. In the Service 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 Service Booklet is only valid if the coolant is renewed or filled up with Mercedes-Benz approved products. Therefore, only use MB 325.0 or 326.0 anticorrosion/antifreeze 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:

 - be at least 50%. This will protect the engine cooling system against freezing down to approximately -35 °F (-37 °C ).

 - not exceed 55% (antifreeze protection to -49 °F [-45 °C ]); otherwise, heat will not dissipate as effectively.

If the coolant level is too low, MB 325.0 or 326.0 anticorrosion/antifreeze should be added. Have the engine cooling system checked for possible leaks.

Windshield/headlamp cleaning system

WARNING
Washer solvent/antifreeze is highly flammable. Do not spill washer solvent/ antifreeze on hot engine parts, because it may ignite and burn. You could be seriously burned.

Use MB SummerFit windshield washer concentrate at temperatures above freezing:

•► Mix 1 part MB SummerFit with 100 parts water.

Use MB WinterFit windshield washer concentrate at temperatures below freezing:

•► At temperatures down to 14 °F(- 10 °C): mix 1 part MB WinterFit with 2 parts water.

•► At temperatures down to -4 °F(- 20 °C): mix 1 part MB WinterFit with 1 part water.

•► At temperatures down to - 20.2 °F(- 29 °C): mix 2 parts MB WinterFit with 1 part water.

Only SummerFit and WinterFit can be mixed. Otherwise, the jets could become blocked.
