General notes You should regularly check the pressure of the emergency spare wheel, particularly prior to long trips, and correct the pressure as nec- essary (Y page 321). The value on the wheel or as given in the "Technical data" section (Y page 329) is valid. i When you are driving with the emergency spare wheel fitted, the tyre pressure loss warning system cannot function reliably. Only restart the tyre pressure loss warning system when the defective wheel has been replaced with a new wheel.

An emergency spare wheel may also be fitted against the direction of rotation. Observe the time restriction on use as well as the speed limitation specified on the emergency spare wheel. Replace the tyres after six years at the latest, regardless of wear. This also applies to the emergency spare wheel.

Removing the emergency spare wheel

Emergency spare wheel Important safety notes G WARNING The wheel/tyre dimensions and the tyre type of the spare wheel/emergency spare wheel and the wheel to be replaced may differ. Fit- ting a spare wheel/emergency spare wheel may severely impair the driving characteris- tics. There is a risk of accident. To prevent hazardous situations: RAdapt your driving style accordingly and

drive carefully.

RNever fit more than one spare wheel/emer- gency spare wheel if the dimesions are dif- ferent to those of the wheel being replaced. ROnly use a spare wheel/emergency spare wheel briefly if the dimesions are different to those of the wheel being replaced.

RDo not switch off ESP®. RHave the spare wheel/emergency spare wheel in question replaced at the nearest qualified specialist workshop. Make sure that the wheel/tyre dimensions and tyre type are correct.

ist workshops: (Y page 24).

Information on technical data

You can find technical data on the Internet at: http://www.mercedes-benz.com i The technical data was determined in accordance with EC Directives. All data applies to the vehicle's standard equip- ment. It may therefore differ for vehicles with optional equipment. You can obtain further information from a Mercedes-Benz Service Centre.

Vehicle electronics Tampering with the engine electron- ics ! Only have work carried out on the engine electronics and its associated parts, such as control units, sensors and connector leads, at a qualified specialist workshop. Vehicle components may otherwise wear more quickly and the vehicle's operating permit may be invalidated.

Retrofitting two-way radios and mobile phones (RF transmitters) G WARNING If RF transmitters are tampered with or not properly retrofitted, the electromagnetic radi-

ation they emit can interfere with the vehicle electronics. This may jeopardise the opera- tional safety of the vehicle. There is a risk of an accident. You should have all work on electrical and electronic components carried out at a quali- fied specialist workshop. G WARNING If you use the RF transmitter in the vehicle in an improper way, its electromagnetic radia- tion can disrupt vehicle electronics, e.g. if: Rthe RF transmitter is not connected to an

exterior aerial

Rthe exterior aerial is fitted incorrectly or is

not a low-reflection aerial

This can jeopardise the operating safety of the vehicle. There is a risk of an accident. Have the low-reflection exterior aerial fitted at a qualified specialist workshop. When oper- ating in the vehicle, always connect the RF transmitter to the low-reflection exterior aer- ial.

! The operating permit may be invalidated if the instructions for installation and use of RF transmitters are not observed. In particular, the following conditions must be complied with: Ronly approved wavebands may be used. Robserve the maximum permissible out-

put in these wavebands.

Ronly approved aerial positions may be

used.

Observe the notes on operating mobile phones (Y page 279). The following aerial positions may be used for the correct installation of RF transmitters:

Approved aerial positions : Front roof area ; Rear roof area = Rear wing i On vehicles with panorama sliding sun- roof, fitting an aerial to the front roof area is not permitted. On the rear wing, it is recommended that you position the aerial on the side of the vehicle closest to the centre of the road. Use Technical Specification ISO/TS 21609
(Road Vehicles – "EMC guidelines for fitting aftermarket radio frequency transmitting equipment") when retrofitting RF (radio fre- quency) transmitters. Comply with the legal requirements for add-on parts. If your vehicle has fittings for two-way radio equipment, use the power supply or aerial connections intended for use with the basic wiring. Be sure to observe the manufacturer's additional instructions when installing. Deviations with respect to wavebands, maxi- mum transmission outputs or aerial positions must be approved by Mercedes-Benz.

Petrol (EN 228, E DIN 51626-1) Fuel grade (AMG vehicles) ! Only refuel using super unleaded petrol with at least 98 RON/88 MON that con- forms to European standard EN 228 or an equivalent specification. You can otherwise impair engine output or damage the engine.

! Premium-grade unleaded petrol with an octane rating of 95 RON/85 MON may be used as a temporary measure if the recom- mended fuel is not available. This may reduce engine performance and increase fuel consumption. As much as possible, avoid driving at full throttle.

! Regular unleaded petrol with an octane rating of 91 RON/82.5 MON may also be used as a temporary measure if the recom- mended fuel is not available. Doing so results in noticeably higher fuel consumption, and the engine power output is noticeably reduced. Avoid driving at full throttle. If only regular unleaded petrol with an octane rating of 91 RON/82.5 MON or lower is available, you must have the vehi- cle adapted to this fuel at a qualified spe- cialist workshop.

i E10 fuel contains up to 10% bioethanol. Your vehicle is suitable for use with E10
fuel. You can refuel your vehicle using E10
fuel.

Fuel grade (except AMG vehicles) ! 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 sys- tem. 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.

! Only refuel using premium-grade unlea- ded petrol with at least 95 ROZ/85 MOZ, that conforms to European standard EN 228 or E DIN 51626–1 or an equivalent specification. Fuel of this specification can contain up to 10 % ethanol. Fuel that does not conform to EN 228 or E DIN 51626–1 can lead to increased wear and damage the engine and exhaust sys- tem.

! Only use the fuel recommended. Operat- ing the vehicle with other fuels can lead to engine failure.

! Do not use the following:

RE85 (petrol with 85% ethanol) RE100 (100% ethanol) RM15 (petrol with 15% methanol) RM30 (petrol with 30% methanol) RM85 (petrol with 85% methanol) RM100 (100% methanol) RPetrol with additives containing metal RDiesel Do not mix such fuels with the fuel recom- mended for your vehicle. Do not use addi- tives. 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 fur- ther information from any Mercedes-Benz Service Centre.

Usually you will find information about the fuel grade on the pump. If you cannot find the label on the petrol pump, ask the filling sta- tion staff. i E10 fuel contains up to 10% bioethanol. Your vehicle is suitable for use with E10
fuel. You can refuel your vehicle using E10
fuel.

i A 200 BlueEFFICIENCY, A 250 BlueEF- FICIENCY: as a temporary measure, if the

recommended fuel is not available, you may also use unleaded petrol with an octane rating of 93 RON/83 MON. All other models: as a temporary meas- ure, if the recommended fuel is not availa- ble, you may also use unleaded petrol with an octane rating of 91 RON/82 MON. This may reduce engine performance and increase fuel consumption. Avoid driving at full throttle and sudden acceleration. Never refuel using fuel with a lower RON/MON. i In some countries, the available petrol

may not be sufficiently low in sulphur. This fuel can temporarily produce unpleasant odours, especially on short journeys. As soon as sulphur-free fuel (sulphur content < 10 ppm) is used for refuelling, the odours are reduced.

Information on refuelling (Y page 159). Additives ! Operating the engine with fuel additives can cause wear in the fuel high-pressure pump and contaminate the entire fuel sys- tem. The repair costs are high. 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. More information about recommended additives can be obtained from any Mercedes-Benz Service Centre. One of the major problems with low-grade fuel is the creation of carbon deposits during the process of burning fuel. Mercedes-Benz recommends that you use fuel brands that have additives. If you use fuels without these additives for a longer period of time, there may be a build-up of carbon deposits. These will form especially on the inlet valves and in the combustion chamber. This could lead to engine running problems, e.g.: Rlonger engine warm-up phase Runeven idle

Service products and capacities

341

Rengine noise Rmisfiring Rloss of power In areas where petrol with the required addi- tives is not available, carbon deposits can build up. In this case, Mercedes-Benz recom- mends the use of additives that have been approved for Mercedes-Benz vehicles; see http://bevo.mercedes-benz.com. The quality of the fuel available in some coun- tries may not be sufficient. Residue could build up as a result. In such cases, and in consultation with a Mercedes-Benz Service Centre, the petrol may be mixed with the additive recommended by Mercedes-Benz (part no. A000989254512). You must observe the notes and mixing ratios specified on the container. Consult a Mercedes-Benz Service Centre to view a list of approved products. Observe the instructions for use in the product descrip- tion. Do not mix other fuel additives with fuel. This causes unnecessary costs and could damage the engine.

Diesel (EN 590) Fuel grade G 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 over- heat unnoticed. There is a risk of fire. Never refuel with petrol. Never add petrol to diesel fuel.

! When refuelling, only use diesel fuel that conforms to the European standard EN 590
or is of equivalent quality. Fuel that does not conform to EN 590 can lead to increased wear as well as damage to the engine and exhaust system.

342 Service products and capacities

! Do not use the following:

Rmarine diesel Rheating oil Rbio-diesel Rvegetable oil Rpetrol Rparaffin Rkerosene Do not mix such fuels with diesel fuel and do not use any special additives. This can otherwise lead to engine damage.

! Vehicles with a diesel particle filter: in countries outside the EU, only refuel with low-sulphur Euro diesel with a sulphur con- tent under 50 ppm; otherwise the emission control system could be damaged.

! Vehicles without a diesel particle fil- ter: 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.

Usually you will find information about the fuel grade on the pump. If you cannot find the label on the petrol pump, ask the filling sta- tion staff. Information on refuelling (Y page 159). Low outside temperatures In winter months, diesel fuel with an improved cold flow quality is available. In Europe, the EN 590 standard defines various climate- dependent temperature categories. Malfunc- tions can be avoided by refuelling with diesel fuel that corresponds to the climatic specifi- cations outlined in EN 590. At unusually low outside temperatures, it is possible that the flow characteristics of the diesel fuel could be insufficient. Accordingly, diesel fuel from warmer areas may not be suitable for opera- tion in colder climatic conditions.

i Further information on country-specific fuel properties can be obtained from oil companies, e.g. at filling stations.

Fuel consumption information H Environmental note CO2 (carbon dioxide) is the gas which scien- tists 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: Refficient use of the fuel by the engine Rdriving style Rother non-technical factors, such as envi- ronmental influences or road conditions You can minimise your vehicle's CO2 emis- sions by driving carefully and having it serv- iced regularly.

The vehicle will use more fuel than usual in the following situations: Rat very low outside temperatures Rin urban traffic Ron short journeys Rin mountainous terrain Rwhen towing a trailer i Only for certain countries: you can find

the current consumption and emission val- ues of your vehicle in the COC documents (EU CERTIFICATE OF CONFORMITY). These documents are delivered with your vehicle. The consumption figures were in each case based on the currently applicable version: Rfor vehicles that comply with standards up to and including the EURO 4 standard, in accordance with EU Directive 80/1268/EEC

Rfor vehicles that comply with or exceed the EURO 5 standard, in accordance with Regulation (EC) No. 715/2007

Deviations from these values may occur under normal operating conditions.

Engine oil General notes When handling engine oil, observe the impor- tant safety notes on service products (Y page 338). The quality of the engine oil is decisive for the function and service life of an engine. After extensive tests, Mercedes-Benz approves engine oils that correspond to the current technical standard. Therefore, only Mercedes-Benz approved engine oils may be used in Mercedes-Benz engines. Further information on tested and approved engine oils can be obtained from any Mercedes-Benz Service Centre. Mercedes- Benz recommends that you have the oil change carried out at a qualified specialist workshop. Mercedes-Benz approval is indicated on the oil container by the inscription "MB Approval" and the corresponding designation, e.g. MB Approval 229.51. You can call up an overview of approved engine oils on the Internet at http://bevo.mercedes-benz.com by enter- ing the designation, e.g. 229.5.

Engine oil viscosity

Viscosity describes the flow characteristics of a fluid. If an engine oil has a high viscosity rating, it flows slowly; the lower the viscosity, the faster it flows. Engine oil selection is based on the respective outside temperatures and in accordance with the SAE classification (viscosity). The table shows you which SAE classifications are to be used. The low-temperature properties of

engine oils can be significantly impaired dur- ing operation due to, for example, ageing or soot and fuel accretion. It is therefore strongly recommended to observe regular oil changes using an approved engine oil with the appropriate SAE classification.

Brake fluid G WARNING The brake fluid continuously absorbs mois- ture 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 sub- jected to a heavy load. This would impair brak- ing efficiency. There is a risk of an accident. Have the brake fluid renewed at the prescri- bed intervals.

When handling brake fluid, observe the important safety notes on service products (Y page 338). The brake fluid change intervals can be found in the Service Booklet. Only use brake fluid approved by Mercedes- Benz according to MB Approval 331.0. Information about approved brake fluid can be obtained at any qualified specialist work- shop or on the Internet at: http://bevo.mercedes-benz.com. i Have the brake fluid regularly replaced at

a qualified specialist workshop.

Coolant Important safety notes G WARNING If antifreeze comes into contact with hot com- ponents 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.

! Only add coolant that has been premixed with the desired antifreeze protection. You could otherwise damage the engine. Further information on coolants can be found in the Mercedes-Benz Specifications for Service Products, MB Specifications for Service Products 310.1, e.g. on the Inter- net at http://bevo.mercedes-benz.com. Or contact a qualified specialist workshop.

! 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.

! The engine cooling system is filled with

coolant, which must be renewed after 15 years or after 250,000 kilometres at the latest.

When handling coolant, observe the impor- tant safety notes on service products (Y page 338). The coolant is a mixture of water and anti- freeze/corrosion inhibitor. It performs the following tasks: Ranti-corrosion protection Rantifreeze protection Rraising the boiling point If antifreeze/corrosion inhibitor is present in the correct concentration, the boiling point of the coolant during operation will be approx- imately 130 †. The antifreeze/corrosion inhibitor concentra- tion in the engine cooling system should: Rbe at least 50%. This will protect the engine

cooling system against freezing down to approximately -37 †.

Rnot exceed 55% (antifreeze protection

down to -45 †). Heat will otherwise not be dissipated as effectively.

Service products and capacities

345

If the vehicle has lost coolant, top it up with equal amounts of water and antifreeze/cor- rosion inhibitor. Mercedes-Benz recommends an antifreeze/ corrosion inhibitor concentrate in accord- ance with MB Specifications for Service Prod- ucts 310.1. The coolant is checked at every maintenance interval at a qualified specialist workshop. i When the vehicle is first delivered, it is fil-

led with a coolant mixture that ensures adequate antifreeze and corrosion protec- tion.

Windscreen washer system and head- lamp cleaning system Important safety notes G 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 con- centrate is spilled next to the filler neck.

! 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.

! Do not use distilled or de-ionised water in the washer fluid reservoir. Otherwise, the level sensor may be damaged.

! Only the washer fluids SummerFit and WinterFit can be mixed. Otherwise, the spraying nozzles could become blocked.

When handling washer fluid, observe the important safety notes on service products (Y page 338).

24 GHz radar sensor system (country overview)

The 24 GHz radar sensor system requires separate approval for each country. When you are driving in a country in which the radar sensor system is not approved, you must deactivate the system using the on-board computer (Y page 223). The current country overview can be obtained from a Mercedes-Benz Service Centre or on the Internet at: http://www.mercedes-benz.de/betriebsanleitung. Vehicles with a navigation system: the radar sensor system is deactivated automatically near radio telescope facilities. A display message appears in the multifunction display to tell you that the radar sensor system is being switched off (Y page 246). If Blind Spot Assist is active, it will be deactivated automatically (Y page 219). If deactivation does not occur automatically, you must deactivate the radar sensor system using the on-board computer (Y page 223). Vehicles without navigation and vehicles for Australia: you must deactivate the radar sensor system using the on-board computer when you are near a radio telescope facility (Y page 223).
