Additives for approved service products are neither required nor permitted. Approved fuel additives are the exception. Additives can cause engine damage and must therefore not be added to the service products.

The use of additives is always the responsibility of the vehicle operator. The use of additives may result in the restriction or loss of your implied warranty entitlements.

Fuel

Important safety notes

../../../../global/pictures_mb/symb_achtung.png

WARNING

Fuel is highly flammable. Improper handing of fuel creates a risk of fire and explosion.

Avoid fire, naked flames, smoking and creating sparks under all circumstances. Switch off the engine and, if applicable, the auxiliary heating before refuelling.

../../../../global/pictures_mb/symb_achtung.png

WARNING

Fuels are poisonous and hazardous to health. There is a danger of injury.

Do not swallow fuel or let it come into contact with skin, eyes or clothing. Do not inhale fuel vapours. Keep fuels out of the reach of children.

If you or others come into contact with fuel, observe the following:

  • Wash the fuel off any affected areas of skin with water and soap immediately.

  • If you get fuel in your eyes, rinse them thoroughly with clean water immediately. Seek immediate medical attention.

  • If fuel is swallowed, seek immediate medical attention. Do not induce vomiting.

  • Change any clothing that has come into contact with fuel immediately.

When handling, storing and disposing of fuels, please observe the relevant regulations.

Petrol

Fuel grade
../../../../global/pictures_mb/symb_ruf.png

Do not use diesel to refuel vehicles with a petrol engine. Do not switch on the ignition if you accidentally refuel with the wrong fuel. Otherwise, fuel can enter the fuel system. Even small amounts of the wrong fuel could result in damage to the fuel system and the engine. Notify a qualified specialist workshop and have the fuel tank and fuel lines drained completely.

../../../../global/pictures_mb/symb_ruf.png

Only refuel using unleaded petrol with at least 95 RON/85 MON that conforms to European standard EN 228 or E DIN 51626-1 or an equivalent specification.

Fuel with this specification may contain up to 10 % ethanol.

../../../../global/pictures_mb/symb_ruf.png

Do not use the following:

  • E85 (petrol with 85% ethanol)

  • E100 (100% ethanol)

  • M15 (petrol with 15% methanol)

  • M30 (petrol with 30% methanol)

  • M85 (petrol with 85% methanol)

  • M100 (100% methanol)

  • Petrol with additives containing metal

  • Diesel

Do not mix such fuels with the fuel recommended for your vehicle. Do not use additives. This can otherwise lead to engine damage. This does not include cleaning additives for the removal and prevention of residue build-up. Petrol must only be mixed with additives recommended by Mercedes-Benz; see "Additives". You can obtain further information from any Mercedes-Benz Service Centre.

../../../../global/pictures_mb/symb_ruf.png

If you are using drums or canisters to refuel the vehicle, you should filter the fuel before adding it.

This will prevent malfunctions in the fuel system due to contaminated fuel.

E10 fuel contains an admixture of up to 10% bioethanol. Your vehicle is E10 compatible. You can refuel your vehicle with E10 fuel.

If the recommended fuel is not available, you may, but only as a temporary measure, use unleaded petrol with an octane rating of 91 RON/82.5 MON. This may reduce the engine's performance and increase fuel consumption. Avoid driving at full throttle.

../../../../global/pictures_mb/symb_info.png

You will generally find information about the fuel grade on the filling pump. If there is no identification on the filling pump, consult a filling station attendant.

For more information about refuelling more.

Fuel additives
../../../../global/pictures_mb/symb_ruf.png

Operating the engine with fuel additives added later can lead to engine failure. Do not mix fuel additives with fuel. This does not include additives for the removal and prevention of residue build-up. Petrol must only be mixed with additives recommended by Mercedes-Benz. Observe the instructions for use in the product description. More information about recommended additives can be obtained from any Mercedes-Benz Service Centre.

One of the main issues with a poor fuel grade is that deposits may result from the combustion process. Mercedes-Benz recommends using brand-name fuels with additives.

If you use fuels without these additives for a long period of time, deposits can form. This primarily forms on the inlet valve and in the combustion chamber.

This can cause problems to occur with the engine, e.g.:

  • a longer engine warm-up phase

  • uneven idling

  • engine noises

  • misfiring

  • loss of power

In regions where petrol with the necessary additives is not available, deposits can occur. In this case, Mercedes-Benz recommends using additives approved for Mercedes-Benz vehicles, see http://bevo.mercedes-benz.com.

In some countries, the available fuel grade may be inadequate. This may result in deposits. In such cases, the additive recommended by Mercedes-Benz should be added by a Mercedes-Benz Service Centre (part number A000989254510). You must observe the notes and mixing ratios indicated on the container.

For a list of approved products, consult a Mercedes-Benz Service Centre. Follow the instructions in the product description.

Do not add other fuel additives to the fuel. This results in unnecessary costs and can damage the engine.

Diesel

Fuel grade
../../../../global/pictures_mb/symb_achtung.png

WARNING

If you mix diesel fuel with petrol, the flash point of this fuel mixture is lower than that of pure diesel fuel. When the engine is running, components in the exhaust system may overheat unnoticed. There is a risk of fire.

Never refuel with petrol. Never add petrol to diesel fuel.

../../../../global/pictures_mb/symb_ruf.png

Only refuel using commercially-available automotive diesel fuel that conforms to the European standard EN 590 (or equivalent national fuel standards). Fuels such as alternative fuels (bio-diesel), marine diesel, heating oil etc. are not permitted.

Do not use fuel additives. There is otherwise a risk of impaired engine performance or engine and catalytic converter damage.

../../../../global/pictures_mb/symb_ruf.png

Vehicles with diesel particle filters: in countries outside the EU, only use low sulphur Euro diesel with a sulphur content of under 50 ppm. Otherwise, the emission control system could be damaged.

../../../../global/pictures_mb/symb_ruf.png

Vehicles without a diesel particle filter : in countries where only diesel fuel with a high sulphur content is available, you will need to carry out your vehicle's oil change at shorter intervals. More information about the interval for oil change can be obtained from any qualified specialist workshop.

../../../../global/pictures_mb/symb_ruf.png

If you are using drums or canisters to refuel the vehicle, you should filter the fuel before adding it.

This will prevent malfunctions in the fuel system due to contaminated fuel.

Information about current country-specific fuel sulphur content is available:

../../../../global/pictures_mb/symb_info.png

You will generally find information about the fuel grade on the filling pump. Otherwise, ask the filling station attendant.

../../../../global/pictures_mb/symb_info.png

You can obtain information about modification options for operation with alternative fuels (bio-diesel fuels) from any Mercedes-Benz Service Centre.

Diesel at very low outside temperatures
../../../../global/pictures_mb/symb_achtung.png

WARNING

If you heat fuel system components, e.g. with a hot-air gun or naked flame, these components could be damaged. This can cause fuel to escape and ignite. Depending on the type of damage, fuel may also not escape until the engine is running. There is a risk of fire and explosion.

Never heat fuel system components. Contact a qualified specialist workshop to rectify the malfunction.

At very low outside temperatures, paraffin may separate from the diesel fuel resulting in inadequate flow characteristics.

Malfunctions resulting from paraffin separation can only be rectified by heating the entire fuel system. Park the vehicle in a heated garage, for example.

To prevent operating problems, diesel with better flow qualities is offered during the winter months.

Winter diesel fuels in the Federal Republic of Germany and other Central European countries are reliable up to an outside temperature of mbsymb6_inv_00d2.png22 corposwgl_2020.png . Winter diesel, which can be used without difficulties at the temperatures normally encountered, is available in most countries.

Fuel additives
../../../../global/pictures_mb/symb_ruf.png

Do not use fuel additives. Fuel additives can cause malfunctions and engine damage.

Do not add any petrol or kerosene to the diesel fuel to improve flow characteristics. Such flow improvers reduce the lubricant properties of the diesel fuel. This can result in damage to the fuel injection system, for example.

Information on fuel consumption

../../../../global/pictures_mb/symb_baum.png

Environmental note

CO2 (carbon dioxide) is the gas which scientists believe to be principally responsible for global warming (the greenhouse effect). Your vehicle's CO2 emissions are directly related to fuel consumption and therefore depend on:

  • efficient use of the fuel by the engine

  • driving style

  • other non-technical factors, such as environmental influences, road conditions or traffic flow

You can minimise your vehicle's CO2 emissions by driving carefully and having it serviced regularly.

../../../../global/pictures_mb/symb_info.png

Only for certain countries: the respective current consumption and emission values of your vehicle can be found in the COC papers (EC CERTIFICATE OF CONFORMITY). These documents are supplied when the vehicle is delivered.

Consumption figures were found in the currently valid respective version:

  • for vehicles up to and including the Euro 4 standard according to EU Directive 80/1268/EEC

  • for vehicles from the Euro 5 standard according to regulation (EC) no. 715/2007

Fuel consumption depends on:

  • the type of vehicle

  • the style of driving

  • the operating conditions

  • the type or quality of the fuel used

The vehicle will use more fuel than usual in the following situations:

  • at very low outside temperatures

  • in urban traffic

  • during short journeys

  • in mountainous terrain

  • when towing a trailer

To keep fuel consumption low, observe the advice in the "Protection of the environment" section more.

The following components of the different vehicle versions influence fuel consumption:

  • tyre sizes, tyre tread, tyre pressure, tyre condition

  • transmission ratios for the drive assemblies

  • additional equipment (e.g. air-conditioning system, auxiliary heating system)

For these reasons, the actual consumption figures for your vehicle may deviate from the consumption figures determined according to EU Directive 80/1268/EEC.

Data concerning fuel consumption are recorded in the on-board computer; use the steering wheel buttons to call up the Trip computer menu more.

Engine oil

General notes

When handling engine oil, observe the important safety notes on service products more.

The quality of the engine oil used is of decisive importance for the engine's functionality and operating life. Mercedes-Benz continually approves engine oils based on complex experiments according to the current state of the art.

Therefore, only Mercedes-Benz approved engine oils may be used in Mercedes-Benz engines. Mercedes-Benz recommends having the oil changed at a qualified specialist workshop.

Information about approved engine oils can be obtained:

Mercedes-Benz approval is indicated on the oil container by the inscription "MB Approval" and the corresponding designation, e.g. MB Approval 229.5.

Designations of the approved engine oils for your vehicle

Petrol engines

All models

228.51, 229.31, 229.51

../../../../global/pictures_mb/symb_info.png

In certain countries, different engine oils can be used, provided that the maintenance intervals are reduced. For more information, please contact a qualified specialist workshop.

Mercedes-Benz recommends that you only use approved multi-grade engine oils of the SAE classes SAE 0W-30 and SAE 0W-40 or SAE 5W-30 and SAE 5W-40. These engine oils ensure optimum lubrication even at very low outside temperatures more.

When topping up, we recommend that you only use engine oil of the same grade (MB Approval designation) and SAE class as the oil filled at the last oil change.

../../../../global/pictures_mb/symb_info.png

If the engine oils listed in the table are not available, you may add the following engine oils until the next oil change:

  • petrol engines: MB Approval 229.1 or ACEA A3

  • diesel engines: MB Approval 228.5, 229.3, 229.5 or ACEA C3

This must only be added once and the amount must not be greater than 1.0 l.

Subsequently, have the engine oil changed at the earliest possible opportunity.

../../../../global/pictures_mb/symb_ruf.png

Using engine oils of another grade quality is not permitted.

Capacities

../../../../global/pictures_mb/symb_ruf.png

Do not add too much oil. Topping up with too much engine oil can result in damage to the engine or to the catalytic converter. Have excess engine oil siphoned off.

Additives

../../../../global/pictures_mb/symb_ruf.png

Do not use any additives with the engine oil. This could damage the engine.

Engine oil viscosity

../../../../global/pictures_mb/symb_ruf.png

If the SAE viscosity class of the engine oil used does not cover the outside temperature range in which you are operating the vehicle, it must be changed in good time, in particular before the cold season commences. Using an engine oil that does not have adequate temperature characteristics can lead to engine damage.

The temperature range information of the SAE classification always refers to that of fresh oil. The temperature characteristics of the engine oil may deteriorate significantly as a result of ageing during vehicle operation, especially at low outside temperatures.

For this reason, Mercedes-Benz recommends that the engine oil be changed before the cold season commences. Use an approved engine oil of the specified SAE class.

images/img548ec7777286dbbd351f19150d1af8df_1_--_--_JPG72.jpg Engine oil SAE classification

Viscosity indicates 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.

Depending on the respective outside temperatures, select an engine oil according to SAE classification (viscosity). The table displays the SAE classification to be used. The low temperature characteristics of engine oils can noticeably deteriorate during operation, e.g. from ageing, soot and fuel accretion. For this reason, regular oil changes using an approved engine oil from the suitable SAE classification are urgently recommended.

Oil change

Oil change intervals depend on the vehicle's operating conditions and the quality of the engine oil used. The on-board computer automatically shows the date for the next oil change as an event message in the display.

Only by using engine oil with a particularly high quality grade, e.g. according to Sheet Number 228.51 of the Mercedes-Benz Specifications for Service Products, can the maximum interval for oil change be achieved.

Mercedes-Benz recommends having the oil changed at a qualified specialist workshop.

Information about oil consumption

../../../../global/pictures_mb/symb_ruf.png

If the vehicle is predominantly used for short-distance driving, this could lead to a fault in the automatic cleaning function for the diesel particle filter. As a result, fuel may accumulate in the engine oil and cause engine failure.

Depending on the driving style, the vehicle consumes a maximum of 1.0 l of engine oil every 1,000 km.

Oil consumption may be higher if:

  • the vehicle is new.

  • you mainly operate the vehicle under arduous operating conditions.

  • you frequently drive at high engine speeds.

Regular maintenance is one of the preconditions for moderate rates of consumption.

You can only estimate the oil consumption after you have driven a considerable distance.

Check the engine oil level on a regular basis, e.g. weekly or each time you refuel more.

Brake fluid

../../../../global/pictures_mb/symb_achtung.png

WARNING

The brake fluid continuously absorbs moisture from the air. This results in the boiling point of the brake fluid lowering. If the boiling point of the brake fluid is too low, vapour pockets may form when the brakes are subjected to a heavy load. This would impair braking efficiency. There is a risk of an accident.

Have the brake fluid renewed at the prescribed intervals.

../../../../global/pictures_mb/symb_ruf.png

Brake fluid corrodes paint, plastic and rubber. If brake fluid comes into contact with paint, plastic or rubber, rinse with water immediately.

When handling, storing and disposing of brake fluid, please observe the relevant regulations and the safety notes in the "Service products and capacities" section more.

Over a period of time, the brake fluid absorbs moisture from the air. This reduces its boiling point.

Have the brake fluid renewed every 2 years at a qualified specialist workshop.

../../../../global/pictures_mb/symb_info.png

There is usually a notice in the engine compartment to remind you when the next brake fluid change is due.

Use only approved brake fluids that comply with the Mercedes-Benz Specifications for Service Products. Always check for the identification DOT 4 plus.

Information about approved brake fluids can be obtained:

Coolant

Important safety notes

../../../../global/pictures_mb/symb_achtung.png

WARNING

If antifreeze comes into contact with hot components in the engine compartment, it may ignite. There is a risk of fire and injury.

Let the engine cool down before you top up the antifreeze. Make sure that antifreeze is not spilled next to the filler neck. Thoroughly clean the antifreeze from components before starting the engine.

../../../../global/pictures_mb/symb_ruf.png

Take care not to spill any coolant on painted surfaces. You could otherwise damage the paintwork.

When handling, storing and disposing of coolant and antifreeze, please observe the relevant regulations and the safety notes in the "Service products and capacities" section more.

Coolant additive with corrosion/antifreeze protection

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

  • corrosion protection

  • antifreeze protection

  • raising the boiling point

When the vehicle is first delivered, it is filled with a coolant mixture that ensures adequate antifreeze and corrosion protection. Coolant must remain in the engine cooling system all year round to ensure corrosion protection and a higher boiling point - even in countries with high outside temperatures.

To prevent damage to the engine cooling system, use only approved corrosion inhibitor/antifreeze that complies with the Mercedes-Benz Specifications for Service Products.

Mercedes-Benz recommends corrosion inhibitor/antifreeze that meets the requirements in Mercedes-Benz Specifications for Service Products Sheet Number 310.1.

Information about antifreeze/corrosion inhibitors approved by Mercedes-Benz is available:

Check the corrosion inhibitor/antifreeze concentration in the coolant every six months.

The percentage of corrosion inhibitor/antifreeze additive in the engine cooling system should:

  • be at least 50%. This way, the engine cooling system is protected against freezing down to approximately corposwgl_002d.png37 corposwgl_2020.png .

  • not exceed 55% (antifreeze protection down to corposwgl_002d.png45 corposwgl_2020.png ). Otherwise, heat will not be dissipated as effectively.

If there has been coolant loss, do not refill only with water. If the vehicle has lost coolant, top up with equal parts water and corrosion inhibitor/antifreeze additive. The water used as part of the coolant mixture must fulfil certain requirements; these are usually fulfilled by drinking water. If the water quality is not sufficient, you must treat the water.

Further information may be obtained at any qualified specialist workshop.

Coolant additive without corrosion inhibitor/antifreeze (exceptional case)

../../../../global/pictures_mb/symb_ruf.png

As an exception, if antifreeze protection is not required (e.g. in countries with continuously hot climates), it is permissible to add a coolant additive to the water in accordance with Sheet No. 312.0 of the Mercedes-Benz Specifications for Service Products instead of a corrosion inhibitor/antifreeze agent. Improvers (corrosion-inhibiting oils) are not permitted.

In this case, renew the coolant annually.

Further information about the necessary water quality and approved coolant additives without antifreeze properties can be obtained from all Mercedes-Benz Service Centres.

Maintenance interval

Have the coolant renewed every 15 years .

Important safety notes

../../../../global/pictures_mb/symb_achtung.png

WARNING

Windscreen washer concentrate is highly flammable. If it comes into contact with hot engine components or the exhaust system it could ignite. There is a risk of fire and injury.

Make sure that no windscreen washer concentrate is spilled next to the filler neck.

../../../../global/pictures_mb/symb_ruf.png

Only use washer fluid that is suitable for plastic lamp lenses, e.g. MB SummerFit or MB WinterFit. Unsuitable washer fluid could damage the plastic lenses of the headlamps.

Observe also the safety notes in the "Service products and capacities" section.

Mixing ratio

Add windscreen washer concentrate to the washer fluid all year round. Adapt the mixing ratio to the outside temperatures.

At temperatures above freezing:

Top up the washer fluid reservoir with a mixture of water and windscreen washer concentrate, e.g. Summerwash to prevent smearing.

At temperatures below freezing:

Top up the washer fluid reservoir with a mixture of water and windscreen washer concentrate, e.g. Winterwash if there is a danger of frost.

This prevents washer fluid from freezing on the windscreen.
